Evidence-to-Conclusions Models: the Goal of Science

Knowing reliability and validity numbers, along with information about previously examined groups, cannot themselves tell a decision-maker whether a test is addressing the precise conceptual world in which there is interest.  What is required is the entire chain of reasoning that links evidence to conclusions.  This paper, which describes parts of an ongoing 7-year project, offers an evidence-to-conclusions chain for the Bricklin Perceptual Scales (BPS) and the Perception-of-Relationships Test (PORT) (Bricklin, 1984; 1989).

The PORT and BPS form the research-derived, data-based part of a comprehensive system: A Comprehensive Custody Evaluation Standard System, ACCESS (Bricklin & Elliot, 1995).  The tests measure the comfort and efficiency with which a child and his or her caretakers exchange a wide variety of interpersonal and emotional information within multiple family contexts.  They are not meant to assign parents to legal categories.  Such assignments are made by the court and depend upon information not obtainable from scientific models.

The following model will be used to organize the evidence-to-conclusions chain for the PORT and BPS.  It consists of four tiers.  The first tier consists of concepts, the second of principles.  Principles state the relations among concepts.  Empirical Equivalents, abbreviated EEs, define what one looks for in the world of sensory experience that exemplifies a concept.  What one chooses as the EEs to represent any concept cannot be determined by a scientific process.  All that can be claimed is that other choices may have created better or worse (i.e., different) results.  As Einstein put it, the ways we draw boundaries around our sensory worlds, the physical as well as the mental, are “free creations of the human mind” (Einstein, 1936; 1954; 1984).  Validation refers to the degree to which the relations among the EEs of the concepts correspond to the relations among the concepts as stated in the principles.

The predictor concepts of the tests aim to yield information on how effectively and comfortably a caretaker and child can exchange all manners of information (concerning the caretaker’s offering and modeling of competency skills, emotional support, consistency, etc.) given the child’s age, developmental status and idiosyncratic needs.  At a test level, the concept’s EEs are represented by the test items, a respondent’s responses to the items and the test’s scoring system.

Perhaps the most important tier for a decision-maker involves the EEs chosen to prove what a test claims to measure.  Here we refer to the precise way the independent validating-criteria are selected and measured.  It is with these data that the decision-maker can question whether the test is measuring the decision-area of concern.

Concepts and Empirical Equivalents (EEs) of the Tests

            The conceptual worlds of both the PORT and BPS aim to illuminate the degree to which a child can comfortably and efficiently exchange all manners of information with a parent (or any other assessed individual).  Such interchanges may involve the child’s seeking of psychological closeness and support, help with various tasks, or when a parent is teaching or modeling essential childcare behaviors (competency skills, trustworthiness, etc.).

One conceptual goal was to allow a child to respond nonverbally.  Nonverbal responses reduce loyalty conflicts.  The child is never asked to speak for or against a parent.  Nonverbal responses also help overcome limitations in a child’s expressive vocabulary.  Most (nonprogrammed) children apparently have, and use, a very limited number or words to describe their parents.  (Validity and clinical data given later further prove that our conceptual belief in the superiority of nonverbal over verbal data is well-placed.  They achieve much higher correlations with independently derived confirmatory evidence than do verbal data.)

The conceptual world seeks information from children so that it is possible to compare responses in which the child is consciously aware of what is being revealed to responses in which the child is not aware of what is being revealed, the aim being to help an evaluator detect which responses are driven not by a child’s actual interactions with a parent but rather by various parental pressures (e.g., bribery, intimidation, alienation, or by a child’s desire to save a parent seen as impaired).

            Test data were generated so that an evaluator could differentiate between responses likely to change situationally or rapidly from those of a more stable nature.  New test-retest data offered later, address this challenge.

            Conceptual EEs were selected that could assess the child’s interactions within various family subsystems (e.g., alone with a parent, with both parents simultaneously, within a total family grouping, etc.).  Some evaluators assert such information is not necessary because once the parents are divorced the child will not encounter these configurations.  Not only is this untrue, but ignores the fact that for years to come, perhaps forever, the child will deal with these configurations mentally.

The EEs selected allow a child a wide response range within assessed categories.  The child can express far more than “Mom is better than Dad.”  The child can say that in such-and-such an area e.g., helping with homework, Mom’s range of styles works to “this” degree, and Dad’s to “that” degree.

            The test EEs reflect a child’s developmental and idiosyncratic need-structure, so that an evaluator can ascertain what, for a given child, would be a useful trade-off.  For one child, a parent who has great organizational skills but is a bit cold emotionally may be a good trade-off, while this may not be true for another child, who may profit more from emotional support than parental organization skills.

The seven PORT tasks were chosen from more than 100 that were considered for inclusion in two pilot studies (described in the PORT Manual).  The ones retained were those able to pinpoint which parent engendered a specific test response in a child, and also achieved the highest (nonoverlapping) correlations with the validating criteria.  We also developed and tested a Family Systems Observation format in these pilot studies which will be described later.

            The BPS tasks were also selected because a child’s responses to them were clearly attributable to a specific parent.  The actual childcare areas were chosen in a way that represented the degree to which each conceptual target area appeared among legal statutes, case law and the writings of mental health experts i.e., the teaching, modeling, and offering of competency skills, admirable traits, and emotional support.

 

Validation Issues (Principles)

            In the custody field, everyone might agree on the criterion concept, something we call an arrangement in the “best interests of the child.”  If we now all agreed on exactly how we should measure this, that is, if we all agreed on what the EEs that represent the “best interests of a child” should be, all that would then matter is how accurately (and at what cost) our predictor EEs predicted them.  However, there is no such agreement (Krauss & Sales, 2000, pp. 845-862).  From the decision-maker’s perspective, no matter how accurate a prediction might be, if it does not represent the conceptual world in which there is concern, the predictive data are of no value.  The central question to a decision-maker is the degree to which he or she believes the EEs selected to represent criterion concepts faithfully represent the area of decision concern.

In the following paragraphs we will outline the major features we sought in our choice of criterion EEs as well as the sources of our criterion data.  We will later consider the degree of precision required of validating data in a child custody context.  First, and foremost, the focus was to be on selecting criterion EEs that reflect the comfort and effectiveness with which all manners of information are exchanged between a child and his or her caretakers.  This “goodness of fit” model reflects our conceptual premise that aside from exceedingly polarized extremes there is no meaningful way to formulate a list of  “admirable parental traits.”  Nor can such a list, if one existed, deal with the adequacy of cost-benefit ratios for a given child.

The second major factor was that the criterion EEs  be formulated from data gathered over lengthy periods of time (in our samples, 4 months to 7 years) and arise from multiple and independent sources of information (i.e., represent ecologic validity).

            The main sources of obtaining criterion data were as follows.  The original PORT study used a one-way mirror setup where trained psychologists observed children and their parents interacting in spontaneous, semi-structured and highly structured tasks. 

            We have always considered the richest source of validity data to arise from family therapy notes plus consultation with family therapists who had worked with children and their families over spans of not less than four months and up to seven years.  In these settings, the psychotherapists had opportunities to observe the children interacting with the parents in multiple subsystems (e.g., alone with a parent, with both parents together, with the entire family together etc.) and additionally heard significant numbers of facts obtained from other independent sources such as homes, schools, and communities.  Several psychologists have made the point that there are some criterion data that can only be obtained from psychotherapists, since they would be the only people who would be privy to the information (Miller, 1998).  Here are some examples of parent information that were shared with involved psychotherapists.

            “Whenever she asks me a question, I freeze up, retreat and get angry.”

            “I really don’t like it when he touches me.”

            “He reminds me of my husband, and that upsets me.”

            “I actually go to bed early so she won’t ask me to help her with her homework.”

It is unlikely that anyone except psychotherapists could assemble an array of data that could include such items.

            Another excellent source of criterion data would be custody evaluators.  Custody evaluators typically work with children and their families over many months, and obtain data from multiple and independent sources.  They typically have interview data, observation data, test data, and data obtained from multiple documents.  They also get to interview and observe many collateral informants.

Next would be mental health professionals who have had opportunities to collect data-rich information over significant spans of time.

            Last in quality would be courtroom judges.  However, please note that this is the criterion we are frequently trying to predict.  On the other hand, many of the courtroom judges who make designations have done so with exposure to the test data on which we sought validation.  Hence, agreement rates with courtroom judges are reported as “information.”

The EEs of the original PORT validity criterion concepts (Bricklin, 1989; Bricklin & Bricklin, 1999, p. 340) were a large number of (mostly non-verbal) behavioral interchanges between parents and children observed from behind one-way mirrors by trained psychologists.  This conceptual world was first articulated in the writings of Karen Horney.  Her system, though seemingly simplistic, posited that all interpersonal behaviors (inter- and ultimately intra-personal) can be characterized along three motor or movement dimensions.  These are: toward people (positive); against people (aggressive); away from people (fearful) (Horney, 1945).  Evaluator attention was to focus mainly on the child, since research interest was primarily on what impact parental behavior had on the child and not primarily on what parents knew or did.  Paul Ekman’s body of work, polygraph studies and the like, further point to the advantages of nonverbal over verbal data in assessing “gut-level” responses (Ekman, 1985; Ekman & O’Sullivan, 1991).

The Horney theory was operationalized in the following way.  The following positive categories apply to situations in which the child is either speaking (initiating or responding), just listening, or listening and acting:  smooth, regular breathing patterns; body movements fluid and non-hurried; relaxed and/or smiling facial muscles (no grimaces, etc.); leans toward other person; maintains reasonable eye contact (the evaluators were taught the difference between fearful eye-contact and relaxed eye-contact—the former is motivated by the child’s fear of saying or doing something the parent would object to); moves closer to or initiates physical contact; willing to be hugged; few signs of restlessness (even if a child is ADD-like, it may be that one parent has a far more calming influence than the other parent).

The following (positive) categories apply to situations in which the child is speaking, either initiating or responding: willingness to express annoyance, doubts or confusion (i.e., not trying to be the perfect little child); pauses without fear of losing caretaker’s attention; willing to ask questions; noting from whom the child most frequently and spontaneously seeks help.

The following (positive) categories apply to situations where the child is listening or listening and acting: accepts limits in mainly comfortable manner; muscularly comfortable with failures (no agitated moves); focused attention; facial expression animated and interested; no evidence of leaping-to-action before waiting for the entire “sent message” to be received; open and ready to receive information; willing to explore and take chances; willing to try novel approaches.  (In some of the original pilot-study research, separate accounts were kept of positive interchanges and negative interchanges.  It soon became clear that counting the number of positive interactions only yielded the same conclusionary information required as did counting both.)

The three observing raters watched as the parents and child interacted in spontaneous, semi-structured and structured situations.  Children were given easy and difficult tasks in the simultaneous presence of both parents, and recordings were made of how the parents were approached.  The tasks were selected so that they ranged, for a given child, from “easy-to-solve” to “impossible-to-solve.”  This allowed the observers to note not only how a parent exchanged information with a child when help was needed, but also when help was not needed. The observations were categorized as described below.  Interrater agreement was very high—in the 90 percent range—partly because the categories in which the data were summarized were formulated to match the requirements of the legal system (discussed later):  A > B (or B > A); A @ B; neither A nor B is adequate (Interrater agreement in the number of positive interactions noted were also good, in the 70 to 80 percent range.)  Differences were discussed and reconciled.  The observational rating scheme used in the PORT studies has remained largely intact until now, and has been the prototype of all future observational schemes.  These original criterion EEs achieved a 90 percent agreement rate with the PORT-selected parents-of-choice (POC), and the PORT has gone on to achieve similar rates of agreement with other criteria in about 1,508 cases.

For EEs used as validating criteria in subsequent research, parent-child interactions in a wide variety of sources were utilized.  The most important source was ongoing family therapy sessions, which lasted over time spans of two to seven years.  Since we wanted honest and spontaneous interactions, initial phases of data-gathering focused on non-adversarial families.  Other data were subsequently obtained from custody litigants.  Family therapy interactions obtained from non-warring families gathered over lengthy time periods yield information as close to real-life data as a mental health professional is likely to ever get, short of moving in with a family for several years.  Further, the samples represented a given child functioning within many different subsystems and under differing circumstances.

In the new data to be presented, each mental health professional who made a validity criterion designation had to have continuing contact either with the family of a tested child, or with one who had such contact.  Since we wanted ecologic validity, each validity designator was instructed to use all of the test, documentary, observation and other clinical/life-history information available (except for PORT or BPS scores).  This included numerous consultations with the mental health professionals who had continuing contact with each child and his or her family over the time-spans involved.  The exact questions asked of those who made criterion designations were as follows.  “Which parent (or other caretaker) overall offers and models competency skills, emotional support, discipline and structure in ways that are best suited to a child’s ability to use these responses effectively and comfortably?”  This was followed by a question asking whether any difference between the parents was narrow or substantial.  (“Narrow” was interpreted to mean the parents were approximately equal.)  We further asked whether both parents did not meet even minimal standards of “good-enough” parenting.

            This yields the following choices:  A is substantially better than B; B is substantially better than A; A and B are approximately equal; neither A nor B is even minimally adequate.  At no point did we, in this study, use the term “parent of choice” as was done in some of our earlier research, since the term was confused with that for a parent serving in some legally defined role.  Out tests measure the comfort and effectiveness with which a parent and child can exchange all manners of information.  Other criteria enter the picture when a decision-maker assigns a parent to a legal category.

Summarizing, the EEs of the conceptual targets of the independent validating criteria represent samples drawn from a wide variety of sources (i.e., pointing to convergent validity), are as representative of “real-life” as one is likely to get, were obtained over lengthy time periods and focused on parent-child relations within many family subsystems.

 

What Degree of Precision is Required of Validating Data?

            All mental health professionals who offer validity designations are directed to use judgmental categories that reflect the rather narrow range of choices utilized by our legal system.  Legal decision makers render decisions in two main categories: legal custody and a time-share plan (or physical custody).  In the former category, three choices are typically used: sole custody; shared custody; and very rarely, neither parent should have custody.

            As far as time-share plans are concerned, few judges venture beyond two choices: sole custody or joint custody.  If the former is chosen, the non-custodial parent is usually given a boilerplate arrangement in which he or she has the child every other weekend, plus an overnight in the middle of those weeks when he or she does not have the child for the weekend.  When complex time-share plans are awarded, they are almost always worked out by the parents and/or their attorneys, not by the data or the judge.  Judges rarely, on their own, venture beyond simplistic dispositional categories.  This constricted choice range has some advantages when transferred to a research setting, since it spares the participating professionals the need to make designations beyond those that are required e.g., it avoids hair-spitting arguments about how much better one parent is than the other.  In real life, mental health professionals can, and do, offer more complex and sophisticated suggestions.  Occasionally, judges heed them.

1.     Following, are data on previously tested groups, concurrent and future validity percentages and test-retest stability figures.  Brand new data address the challenge of identifying the conditions under which test data are likely to change over time (i.e., data that pinpoint unstable family systems) and when such changes should be viewed as true changes in the measured variables rather than errors of measurement.  Other new data address the degree to which the PORT is able to effectively assess how the child reacts to various family subsystems.

4-1.         If the Task-Difference-Score (TDS) (over a 6-month interval) was 0 or 1, there was a 10 percent chance the PORT Parent-of-Choice (POC) would shift.  If the TDS was 2 or more, the chance of POC shift was 2 percent.

5.      BPS Test-Retest Stability Data (1964-1997), n=20; n=33

5-1.         If the Item-Difference-Score (IDS) (over a 1-week interval, n=20 and a 6-month interval, n=33) was 0, 1 or 2, there was a 10 percent chance of POC shift.  If the IDS was 3 or more, there was a 2 percent chance of shift.

Please note again that the validity designations, presented next, were matched to the degree of refinement generally required in the legal system: parent A>B; parent B>A; Parent A @ Parent B; Neither A nor B is a good choice.  PORT and BPS data are summarized to yield a designation matching the first 3 of these requirements.  The system of which they are a part—ACCESS—addresses the last choice.  Those who made independent designations never did so on the bases of PORT or BPS data.

Please note, then, that the criterion designation categories yielded by the PORT and BPS do not yield a normal or symmetrical distribution.  Hence, percent-of-agreement is a reasonable way to express our results, and are inherently more user-friendly to many of those who would make decisions on their bases.  Further, it is a lot easier for non-statisticians to comprehend percent-of-agreement rates than product-moment correlations, where fairly large numbers frequently signify modest predictive accuracy.  A test-suggested Parent-of-Choice, abbreviated POC, is never, by itself or as part of our comprehensive system, used either to address legal ultimate issues or to assign a caretaker to a legal category.

Tables 3, 4, 5 and 6 have to do with factors that may influence a change in either a PORT or BPS test-retest POC.  Two central issues are involved.  One is the issue of whether such changes, when they occur, should be considered errors of measurement or, on the other hand, to represent true changes in the measured variables.  The second is a practical issue: to alert evaluators to situations in which a change in POC might be expected.  Our contention is that many of the situations that cause such changes represent true changes in the measured variables.

 

 

Prior attempts to discern situations likely to red-flag a test-retest POC-change, suggested the following as worthy hypotheses: newly emergent developmental and/or idiosyncratic needs; a new person in the child’s life who fills the needs previously served by the prior POC; a POC who has become so absorbed in a high conflict relation that he or she can no longer function in a POC role; a child vulnerable to alienation, intimidation, bribery, or a desire to save a parent seen as impaired. 

There were insufficient follow-up data to address all of these situations.  However, there were enough criterion data to address the following situations.

Table 3 looks at whether a POC is likely to change over time if the child more frequently responds to his or her parents as though they are exactly equal in “value” in multiple family contexts, rather than if the child is able to notice large and/or subtle differences between them and hence values them differently in multiple contexts.  PORT data were selected to address this issue.  On the PORT, either parent can earn up to seven points, depending upon the number of times a given parent is the POC on one of the seven PORT tasks.  Score distributions can be expressed in the following way.  The first number would be the Task points earned by Parent A, the second those earned by Parent B and the last would represent the number of ties.  For example, the designation, 5-2-0 would refer to a situation in which Parent A, being the parent-of-choice (POC) on five PORT tasks, earned five points while Parent B earned two points with zero ties.  The score pattern being tested under this hypothesis is called, for shorthand, the 0-0-7 pattern.  It refers to a situation where the total number of tie scores outnumbered the combined individual scores for the mother and father.  Our past data had suggested two (psychological) conditions under which this could occur.  One would point to a super-resilient child who can make use of whoever happens to be around.  The other would represent a situation in which the child finds each parent to have no special value in a majority of situations.  The clinical data suggest the latter to be more true than the former.  For example, an overall tie score between Mother and Father that is accrued by virtue of a 3-3-1 pattern is not unstable over time while the 0-0-7 pattern is highly unstable.  We considered the 0-0-7 pattern to be unstable because it points to a condition in which the least little shift could make a difference.  That is, if either of the parents becomes more helpful to the child, the POC could change.  This hypothesis seems confirmed by the data.

14.  Table 3 shows the probability of a POC-shift when the A+B Tie scores are greater or lesser than the A+B Total scores.  (See section 21 for further information about what these figures mean.)

Table 4 asks whether test POCs are likely to change over time if a child shows symptoms of ADHD.  Here we wanted to look at whether some children’s experiences of their parental relations are inherently unstable because of psychobiological factors intrinsic to the child.  Hence the criterion question asked of the mental health professionals was: “Based on all the data available to you, do you believe the subject-child meets the requisite diagnostic criteria of ADHD in a clear and convincing manner?”  This hypothesis was not confirmed.

15.  Table 4 reflects the probability of a POC-shift in children diagnosed with AD(H)D.

Table 5 addresses whether a test-POC is likely to change over time if the following two conditions are simultaneously true.  One condition concerns whether one parent is vastly superior to the other in multiple-perspective-taking skills (MPTS).  The other concerns whether the child has consciously complained about an external stressor (explained below).  Hence, mental health professionals who made criterion designations were asked to respond to a question about parental MPTSs.  It was defined to them in the following ways.  “While at a technical level we are looking to find out whether one parent is vastly superior to the other in MPTSs or multivariate thinking, you can operationalize this in the following way.  Is one parent vastly superior to the other in being able to harbor multiple points of view on some subject, and in the ability to think about childcare as well as other life situations from many different perspectives?”  The hypothesis follows from our observation that the behaviors needed to parent younger children require mostly sequential information processing skills.  If one were to verbalize what is required to take care of young children one could say something like this.  “The parent has to be able to say (and enforce): It’s time to get up; it’s time to brush your teeth and wash your face; it’s time to have breakfast; it’s time to go to school; it’s time to do your homework; it’s time to go to bed.”  As children grow older, even slightly (from about 8 years of age on), they must balance many more demands.  Sports activities, expanded circles of friends, burgeoning sexuality, more academic pressures, and so forth, are just a few of the forces that come to bear on children as they age.  It has been our observation that as children grow older they will more and more need a parent who is able to process information in multivariate or simultaneous manners.  Hence it was hypothesized that if the two parents differed greatly in the manner described, it could raise the probability of a shift in POC (toward the parent superior in MPTSs).

The other hypothesis was investigated by asking the MHPs: “Is there some external stressor in the child’s life that he or she has continuously complained about? This could include a new stepparent, new stepsiblings, a new school, a change in homes, or any of such things?”  It has long been our contention that there is no a priori way from merely having knowledge of such stressors to predict whether there will be a POC change.  Some children are quite resilient while others are not.  However, it was our belief that if both of these factors were true, that one parent was vastly superior to the other in MPTSs and there was some external situational stressor, the likelihood of a change in POC would rise.  This hypothesis was confirmed.

16.  Table 5 reflects the probability of a POC-shift when the eventual POC-parent has significantly better multiple-perspective-taking skills than the other, AND the child continually complains about the post-divorce situation.

PORT Adverse Signs and Changes in (POC)

Table 6 looks at whether a POC is likely to change more readily as a child grows older.  It has been our observation that as children grow older (11 years and up), they become far more self-centerdly interested in “shopping around for the best deal” in terms of which household to live in.  Their own circles of friends are increasing and solidifying, and they know which house will offer them the greater range of the freedoms they seek.  This is often the household in which the rules are more relaxed, where they can stay up later, watch more television, go out more frequently, etc.  This hypothesis was not confirmed.

17.  Table 6 reflects the probability of a POC-shift related to a child’s increasing age.

The following items, 18, 19 and 20, deal with hypotheses formulated to confirm prior data gathered on the PORT’s ability to reveal information on how the child functions within several family subsystems.  We sought criterion designations about the 72 subjects who were in some ongoing form of psychotherapy, since the mental health professionals who would make criterion designations would have available to them the greatest amount of information.  (We formulated hypotheses for each of the seven PORT tasks, but there were insufficient data to address those for PORT tasks III, IV, VI and VII.)

Prior research indicated that PORT Task I can reveal which parent, the mother or the father, has been the greater overall source of assets for the child.  The criterion question was: “Based on all of the data available to you, which parent (or caretaker) has been the greater source of assets for the child?”  The agreement rate was 76 percent.

Prior research has indicated that PORT Task II is sensitive to revealing which parent the child is most comfortable with when in a situation in which he or she is alone with that parent.  Therefore, it was hypothesized that those parents who are most frequently the POCs on PORT Task II will be those most frequently designated as the parents with whom the child is most comfortable when in an “alone-with-that-parent” situation.  The criterion question was: “Based on all the data available, which parent is the child more comfortable with when he or she is alone with that parent?”  The agreement rate is 63 percent.

PORT Task V, which asks a child to “Draw your family doing something,” has been shown to reflect the degree to which a child believes that the family is still able to function as a cooperative unit.  Children who draw their family members all doing something together, that is, all working at the same task, for example, cooking a dinner, or rowing a boat, still believe their family can function cooperatively.  Children who draw each member of the family isolated from all the rest, for example, dad out in the yard, mom in the kitchen, etc., have lost faith that their family is able to do this.  The clinical hypothesis was that the parent who is POC on this task is the parent whom the child views as trying the harder to make sure the family continues to function in some kind of cooperative manner.  The criterion question was: “Based on all the data you have, which parent more strives to maintain cooperation, calmness and stability among all the family members?”  The agreement rate was a robust 91 percent (as we had expected).

It was hypothesized that, overall, the data collectively will support our view that nonverbal data yield more accurate and useful information in child custody evaluations than do verbal data.  Technically, the hypothesis claims that responses derived from nonverbal tasks will show higher correlations with independent criterion designations (see item 21).

18.   PORT Task I POC reflects the caretaker in relation to whom the child is acquiring the most overall assets.

18-1.       Agreement rate (n=72) 76 percent

19.  PORT Task II POC reflects the caretaker with whom the child is most comfortable in a situation where he or she is alone with that person.

19-1.      Agreement rate (n=72) 63 percent

20.  PORT Task V POC reflects which caretaker the child believes contributes the most to continuing family unity and cooperation.

20-1.      Agreement rate (n=72) 91 percent

21.  What Clinical Hypotheses are Suggested by Empirical Data From 3,880 Custody Cases?

21-1.      The generally high rates of agreement between test-based selections for POC and those arrived at by a variety of independent sources suggest one can reasonably measure the ongoing nature of the comfort and efficiency with which a child and caretaker exchange information.  The validation data were collected not only from multiple and independent sources, but were the product of data gathered over substantially long intervals, ranging from four months to seven years.

21-2.      Given how closely our concurrent validity numbers matched those obtained from a future-validity paradigm, we can hypothesize that the more concurrent validity methods are ecologic in nature, the more it is reasonable to assume they will yield data comparable to future validation data. 

21-3.      These particular data remained stable over at least an 8-month period (Tables 1 and 2).

21-4.      One can detect score patterns that suggest when family (primarily dyadic) subsystems are likely to be unstable over time.  One of these is when a child is not able to recognize any useful parenting differences between his or her parents (Table 3).

21-5.      The presence of an ADHD pattern in a child does not seem to create instability over time in how the child assigns value to his or her caretakers (Table 4).

21-6.      When one parent is better than the other in multiple-perspective-taking-skills and a child has continually complained about his or her post-divorce situation, we have a red flag that the dyadic family subsystems of which that child is part will be unstable (Table 5).

21-7.      At least in so far as our sample was concerned, a child’s increasing age does not seem to red flag instability.  This was counter to what we believed would be true (Table 6).

21-8.      PORT Task I seems to reasonably reflect the parent who is the greater source of overall assets to the child.

21-9.      Although the evidence is weaker here, a child’s response to PORT Task II seems to indicate the parent with whom the child is most comfortable in a situation where the child is alone with that parent.

21-10.   PORT Task V is strongly predictive of the parent whom the child perceives as contributing the most toward family unity.

21-11.   Nonverbal data both for adults as well as children were more accurate in predicting the validating criteria than were interview and other consciously-sourced data.  Although some of these data were not generated in the current study, it is worth repeating that children’s consciously sourced opinions on POC-choices had only about a fifty percent agreement rate with those of experts.  This was true even with older children, 14 through 16 years of age.  Children’s nonverbal responses had agreement rates with the experts in the ninety- to one-hundred percent range.  In our data, the interview-based opinions of high conflict custody parents are relatively useless.  One parent-questionnaire had 86 questions about which parent the child turns to in times of need.  In adversarial parent cases, the typical scores were 86 to zero.  These scores had no relationship whatsoever to data generated by experts.  On the other hand, nonadversarial parents (from intact families) achieved agreement rates with experts that were quite reasonable (70 to 80 percent range).

21-12.   All of our data collectively suggest that the meaning of a communication is best understood by the response it engenders.  The point is that the latter is often unrelated to what the communicator thinks is the sent-message.  For example, one of our tests categorizes some of a child’s responses into “perception of caretaker competency” and “perception of caretaker emotional supportiveness.”  It was quite interesting to note the hugely divergent subjective experiences that children perceive as “emotional supportiveness.”  For example, disorganized children who have difficulty with planning prioritized sequences often perceive as the more “emotionally supportive” caretaker the one who is most organized.  In a group referenced (normative) paradigm, this caretaker may or may not be seen as “emotionally warm.”  Such children obviously feel more emotionally supported by a parent who reduces chaos in their lives rather than by one who exudes what others might call “warmth.”
