MMPI validity measures: a comparative study of original with alternative indices.

A comparison was made of the original MMPI validity scales (L,F,K,F - K) with validity scales devised subsequently (TR, Ca, Ds, Mp, Ws - Wo) to determine which scales, the older or newer, were better, either alone or combined, in detecting fake-good, fake-bad, and careless responding. This was accomplished by having groups of subjects answer the MMPI first under standard conditions and then, 1 week later, under one of the falsifying conditions. A group of 40 psychiatric patients responded under standard and then fake-good conditions; a group of 40 university students responded under standard and then fake-bad conditions; and a group of 20 students responded under standard and then fake-careless conditions. Results indicate that both the traditional and newer validity indices were equally good at detecting fake-good responding. None of the indices was adequate in detecting careless responses. We conclude, as a consequence of this study, that the newer scales perform a clinically useful function when faking good is suspected on the MMPI.     

The content validity of juvenile psychopathy: an empirical examination

This study examined the content validity of a juvenile psychopathy measure, the Childhood Psychopathy Scale (CPS; D. R. Lynam, 1997), based on a downward translation of an adult instrument, the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). The CPS was compared with two other indices of juvenile psychopathy: (a) an index derived from expert ratings and (b) an empirical index based on correlations with adult psychopathy. The 100 items of the Common Language Q-Sort (CLQ; A. Caspi et al., 1992) provided a common metric for the comparison. Psychopathy and personality were assessed at age 13 years with the mother-reported CPS and the CLQ. Psychopathy was assessed at age 24 years with the interviewer-rated Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Data from over 250 participants of the middle sample of the Pittsburgh Youth Study were used to examine these relations. Item content analyses demonstrated considerable overlap among the three indices, indicating that the downward translation utilizes criteria similar to those of experts and the empirically-derived measure. In addition, these indices, even after removing overlapping items, demonstrated considerable convergence, also supporting the content validity of the downward translation. These results suggest that the downward translation method is adequate for understanding the juvenile psychopathy construct.     

The principles of conventionality and contrast in word learning: an empirical examination

In Study 1, 4-year-olds avoided 2 names for an object when exposed to a common or a proper noun in a puppet's presence or to a common noun in a puppet's absence, but not when exposed to a proper noun in a puppet's absence. In Study 2, 3-year-olds avoided 2 names for an object when the requester for the referent of a second label in a different language was bilingual and present during naming, but not when the speaker was bilingual but absent or monolingual. Study 3 followed up on the results of the first 2 studies. When children could assume that the puppet knew the name the experimenter used, they inferred that the puppet's use of a different name implied a different referential intent.     

Children's embedded figures test: an examination of item difficulty in grades K-4

Indices of item difficulty for both the Tent and the House series of the Children's Embedded Figures Test are reported from a sample of 240 children in grades K-4. Results indicate that the failure rule should be re-considered and the test shortened.     

Beyond alpha: an empirical examination of the effects of different sources of measurement error on reliability estimates for measures of individual differences constructs

On the basis of an empirical study of measures of constructs from the cognitive domain, the personality domain, and the domain of affective traits, the authors of this study examine the implications of transient measurement error for the measurement of frequently studied individual differences variables. The authors clarify relevant reliability concepts as they relate to transient error and present a procedure for estimating the coefficient of equivalence and stability (L. J. Cronbach, 1947), the only classical reliability coefficient that assesses all 3 major sources of measurement error (random response, transient, and specific factor errors). The authors conclude that transient error exists in all 3 trait domains and is especially large in the domain of affective traits. Their findings indicate that the nearly universal use of the coefficient of equivalence (Cronbach's alpha; L. J. Cronbach, 1951), which fails to assess transient error, leads to overestimates of reliability and undercorrections for biases due to measurement error.     

Children's living arrangements following separation and divorce: insights from empirical and clinical research

When parents separate, children typically enter into new living arrangements with each parent in a pattern determined most often by one or both parents or, failing private agreement, as a result of recommendations and decisions by lawyers, therapists, custody evaluators, or family courts. Most of these decisions have been based on cultural traditions and beliefs regarding postseparation parenting plans, visitation guidelines adopted within jurisdictions, unsubstantiated theory, and strongly held personal values and professional opinions, and have resulted since the 1960s in children spending most of their time with one residential parent and limited time with nonresident, or "visiting," parents. A large body of social science and child development research generated over the past three decades has identified factors associated with risk and resiliency of children after divorce. Such research remains largely unknown and untapped by parents and professionals making these crucial decisions about children's living arrangements. This article highlights empirical and clinical research that is relevant to the shape of children's living arrangements after separation, focusing first on what is known about living arrangements following divorce, what factors influence living arrangements for separated and divorced children, children's views about their living arrangements, and living arrangements associated with children's adjustment following divorce. Based on this research, it is argued that traditional visiting patterns and guidelines are, for the majority of children, outdated, unnecessarily rigid, and restrictive, and fail in both the short and long term to address their best interests. Research-based parenting plan models offering multiple options for living arrangements following separation and divorce more appropriately serve children's diverse developmental and psychological needs.     

Children's sense of belonging and parental social capital derived from school

Parents' chance to seek help from other parents of schoolchildren attending the same school is an aspect of parental social capital. This social capital is supposed to contribute to schoolchildren's present sense of belonging to their school, society, and country. The relationship between social capital and a child's sense of belonging may vary as a function of the child's prior sense of belonging. Social capital may give a deeper encouragement or positive effect to children with higher prior sense of belonging (the strength building perspective) or to children with lower prior sense of belonging (the need fulfillment perspective). The author surveyed 289 parents and their schoolchildren in Grades 4-9 in Hong Kong, China, to ascertain which of the two perspectives holds. The results indicated that parental social capital was more highly associated with a child's present belongingness if his or her prior belongingness was high rather than low. This interaction effect is supportive of the strength building perspective.     

The stability of structural measures derived from repertory grids

Although the use of repertory grids in psychological research has proliferated, studies of their psychometric properties are relatively rare. For this reason, we studied the reliability and convergence of several measures of cognitive structure derived from grids, including intensity, percentage of variance accounted for by the first component, cognitive complexity, ordination, extremity of ratings, self-ideal discrepancy, and self-other discrepancy, as well two measures of rating stability, construct consistency and factor loading consistency. Eighty-two Spanish (Catalan) and American participants completed small and large grids on each of four occasions, which enabled exploratory analyses of the impact of grid size and subject characteristics on the structural scores obtained. Results indicated that the majority of scores showed impressive test-relest reliability (modal r = .85 for periods up to 1 month), but also suggested a gradual tightening effect across subsequent administrations. In general, scores intercorrelated in theoretically anticipated ways, converging on the assessment of cognitive differentiation and discrimination of elements within construct dimensions. The results have implications for the reactivity of structural scores to variations in grid format, as well as for use of grids in the study of sex differences and cross-cultural comparisons.     

Children's peer selection: experimental examination of the role of self-perceptions

Although previous studies have examined characteristics of children selected as friends, little research has examined the role played by characteristics of the selecting child. In 2 experimental studies that examined the role of self-perceptions in peer selection, participants (91 seventh graders in Study 1 and 83 third graders in Study 2) viewed various evaluations of themselves. Participants either believed evaluations were written by unfamiliar peers (Study 1) or were asked to imagine that the views of puppets were views of unfamiliar peers (Study 2). Participants were asked to select the peers they wished to meet and interact with. When evaluations were related to specific competence domains, 7th graders preferred positive peers to negative peers, whereas 3rd graders selected peers who viewed them as they viewed themselves. When evaluations were related to global self-worth, children's selections were unrelated to views of their own global worth. Selection of a globally negative peer was associated with attachment-insecurity/maternal-rejection and depressive symptoms.     

Children's competence for assent and consent: a review of empirical findings

This narrative review summarizes the empirical literature on children's competence for consent and assent in research and treatment settings. Studies varied widely regarding methodology, particularly in the areas of participant sampling, situational context studied (e.g., psychological versus medical settings), procedures used (e.g., lab-based vs. real-world approaches), and measurement of competence. This review also identifies several fundamental dilemmas underlying approaches to children's informed consent. These dilemmas, including autonomy versus best interest approaches, legal versus psychological or ethical approaches, child- versus family-based approaches, and approaches that emphasize consent versus those that emphasize assent, have implications for the measurement of children's competence and interpretation of findings. Recommendations for future research in the area of children's informed consent include the use of diverse samples and control groups, development of multidimensional and standardized measures of competence, utilization of multidimensional and standardized measures of competence, utilization of observational methods and longitudinal designs, examination of noncognitive aspects of children's competence and comparison of children's competence for treatment and research decisions.     

The belief in a just world: an examination of reliability estimates across three measures

In this study, we utilized reliability generalization procedures to examine internal consistency estimates across 3 scales measuring the belief in a just world. The distribution of reliability estimates for the measures suggest low to moderate ranges of internal consistency reliability coefficients. The Global Belief in a Just World Scale (Lipkus, 1991) produced the highest average reliability score (alpha = .81) compared to the Just World Scale (Rubin & Peplau, 1973; alpha = .64) and the Just World Scale Revised (Rubin & Peplau, 1975; alpha = .68).     

Children's alcohol cognitions prior to drinking onset: discrepant patterns from implicit and explicit measures

Prior to drinking onset, children report stronger negative versus positive beliefs on self-report alcohol expectancy questionnaires, with some attenuation of this negativity as they transition into adolescence. Traditional alcohol expectancy assessments, however, capture endorsement of deliberative propositions about drinking outcomes. Measurement of implicit alcohol associations may elucidate automatic evaluations, clarifying the role of nondeliberative cognition in the initiation of alcohol use among youth. Few studies have assessed implicit alcohol cognition among children and younger adolescents, with inconsistent findings regarding the nature of these automatic associations within and between age groups. Eighty-nine 3rd and 4th graders and 91 7th and 8th graders completed an alcohol expectancy measure and two unipolar alcohol Implicit Association Tests (IAT) measuring positive and negative alcohol associations independently. On the explicit measure older compared with younger participants rated positive drinking outcomes as more likely and negative outcomes as less likely. Older compared with younger students were also more neutral/moderate in their evaluations of positive drinking outcomes. On the IATs, scores for the full sample indicated negative alcohol associations, and Negative IAT scores were higher for older compared with younger participants. However, the valence of implicit alcohol associations was qualified by the order of explicit versus implicit assessment; for those who completed the IATs prior to the explicit expectancy measure, alcohol associations were positive. Findings replicate and extend prior research conducted with preonset youth. Implications regarding the role of automatic and controlled processes in drinking onset and directions for future work on children's alcohol cognition are discussed.     

Social cues for creativity: The impact of behavioral mimicry on convergent and divergent thinking

We present behavioral mimicry as a social cue for creative thinking. Specifically, we argue that being mimicked by an interaction partner cues convergent thinking by signalling a social opportunity for collaboration, while not being mimicked cues divergent thinking by signalling a social demand for improvisation and innovation. To test this theory, we experimentally manipulated whether individuals were subtly mimicked or not by an experimenter during a 5 min social interaction, and subsequently measured participants’ capacity for convergent thinking (Experiment 1) and divergent thinking (Experiment 2). The results point to the importance of understanding how social relationships influence the creative processes and contributes to the growing understanding of the social function of behavioral mimicry.     

Tracking the dynamics of divergent thinking via semantic distance: Analytic methods and theoretical implications

Divergent thinking has often been used as a proxy measure of creative thinking, but this practice lacks a foundation in modern cognitive psychological theory. This article addresses several issues with the classic divergent-thinking methodology and presents a new theoretical and methodological framework for cognitive divergent-thinking studies. A secondary analysis of a large dataset of divergent-thinking responses is presented. Latent semantic analysis was used to examine the potential changes in semantic distance between responses and the concept represented by the divergent-thinking prompt across successive response iterations. The results of linear growth modeling showed that although there is some linear increase in semantic distance across response iterations, participants high in fluid intelligence tended to give more distant initial responses than those with lower fluid intelligence. Additional analyses showed that the semantic distance of responses significantly predicted the average creativity rating given to the response, with significant variation in average levels of creativity across participants. Finally, semantic distance does not seem to be related to participants’ choices of their own most creative responses. Implications for cognitive theories of creativity are discussed, along with the limitations of the methodology and directions for future research.     

The development of creative cognition across adolescence: distinct trajectories for insight and divergent thinking

We examined developmental trajectories of creative cognition across adolescence. Participants (N = 98), divided into four age groups (12/13 yrs, 15/16 yrs, 18/19 yrs, and 25–30 yrs), were subjected to a battery of tasks gauging creative insight (visual; verbal) and divergent thinking (verbal; visuo‐spatial). The two older age groups outperformed the two younger age groups on insight tasks. The 25–30‐year‐olds outperformed the two youngest age groups on the originality measure of verbal divergent thinking. No age‐group differences were observed for verbal divergent thinking fluency and flexibility. On divergent thinking in the visuo‐spatial domain, however, only 15/16‐year‐olds outperformed 12/13‐year‐olds; a model with peak performance for 15/16‐years‐old showed the best fit. The results for the different creativity processes are discussed in relation to cognitive and related neurobiological models. We conclude that mid‐adolescence is a period of not only immaturities but also of creative potentials in the visuo‐spatial domain, possibly related to developing control functions and explorative behavior.
