Assessment of Psychopathic Traits in Singaporean Adolescents: Validation of the Antisocial Process Screening Device (APSD)

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.     

Resistance to Cultural Intervention: Formation of Inhibitory Collective and children’s Self-Defensive Regulation in a Chinese School

A sequel to the previous article “Roots of Excellence: The Releasing Effect of Individual Potentials through Educational Cultural Intervention in a Chinese School” (in press), the present study is on the unexpected reversal phenomena in the process of cultural intervention. The goal of the intervention is to construct the dynamics of Jiti (well-organized collective in Chinese) through creative activities to promote students’ development. In the intervention, the releasing effect (Wu et al. 2016) emerged as well, but the teacher’s concern about worsening discipline and academic performance evoked and reinforced his habitual notions and practices of education, turning the joint activities into a way of strengthening discipline. The energy that had been discharging at the beginning of the intervention was inhibited, so that many more problematic behaviors took shape. The whole class formed an inhibitory atmosphere, within which pupils formed self-defensive regulation strategies. By comparing with the productive collective in which intervention was effective and analyzing this unexpected reversal process, we can not only see pupils’ self-construction status in the inhibitory culture but illuminate the formation of the teacher’s resistance to educational and cultural transformation as well. Resistance is originated from teachers not being able to interpret pupils’ inner developmental needs but instead anxious about the ongoing problems.     

Validation of a single-item measure of usual physical activity

The purpose of this study was to assess the reliability and validity of a single-item measure of Usual Physical Activity and to assess its usefulness as a physical activity tool for perimenopausal women. 188 perimenopausal women participated (age: M = 47 yr., SD = 3; range = 40-55). Data were collected using the Women's Health Assessment Scale, the Physical Activity Questionnaire, the Perimenopause-related Quality of Life Scale, a health history and demographic questionnaire, and the rater. Scores were stable over a 2-wk. interval. Convergent validity was supported by a correlation of .66 between ratings on Usual Physical Activity and the Physical Activity Questionnaire. Concurrent validity was supported by the association of the rating of Usual Physical Activity with three parameters of Body Mass Index, psychosomatic symptoms, and perimenopause related quality of life, known to be associated with physical activity. Highly active women had a lower Body Mass Index than less active and inactive women. Active women tended to report fewer and less distressing psychosomatic symptoms and better quality of life. These findings support the use of rating of Usual Physical Activity to classify perimenopausal women into categories of physical activity.     

The effect of familial sinistrality on the relation between schizophrenialike thinking and pseudoneglect

We have recently reported a correlation between schizophrenialike symptoms and the degree of pseudoneglect in healthy right-handers. We aimed to investigate the effect of familial sinistrality (FS) on this relation. Seventy-six healthy right-handers were divided into four groups on the basis of gender and FS. A computerized version of Corsi's task was used as the visuospatial task. Subjects filled in the Magical Ideation Scale (MI), which asked for delusionlike beliefs, and performed the Corsi's task using each hand. Performance of both hemispaces was separately evaluated. In all groups, performance of the left hemispace was better than that of the right hemispace and FS+ subjects performed better than FS- subjects. When the right hand was used, performance was correlated to MI scores only for FS- groups. Findings suggest that the correlation between right-sided neglect and proneness to schizotypy in normal right-handers is affected by FS.     

The role of inhibition in the regulation of sequential action

We investigated the regulation of sequential action using a new paradigm. Participants learned a sequence of seven stimulus categories and then monitored for them during successive displays. All displays were instances of these categories, presented in pseudorandom order. On each trial, participants monitored for an instance of Category 1, pressed a key on a computer keyboard, then monitored for an instance of Category 2, pressed a key on the keyboard, and so on for all seven categories. Thus, a perfect trial contained exactly seven responses. Intrusion errors were classified as a function of ordinal distance from the current serial position ( n ). Fewer intrusion errors were made at near serial positions than at far ones, suggesting a gradient of lateral inhibition. In addition, more intrusions were made on n + 1 categories than n − 1 categories, suggesting greater availability of intended than completed goals. In accord with current models of sequential action, the results indicate lateral and self-inhibition as important mechanisms in regulation of sequential action.     

Evaluating Gender Biases on Actual Job Performance of Real People: A Meta‐Analysis1

This study examined gender bias on job performance in work settings where confounding variables (e. g., organizational level, experience, education) were cautiously taken into consideration to ensure fair comparisons. Although previous meta‐analyses examined gender biases on evaluations, findings in tightly controlled laboratory environments may differ from those in highly complicated field studies. We found little evidence of overall gender bias in performance appraisals in nonconfounded field studies. However, there were significant pro‐male biases when only men served as raters. Measure‐specific gender stereotypicality, instead of genera! stereotypicality about the job, produced gender bias in performance appraisal. Masculine measures produced pro‐male bias, and feminine measures produced pro‐female bias.     

Breadth and intensity: Salient,separable, and developmentally significant dimensions of structured youth activity involvement

In recent years, an impressive volume of evidence has accumulated demonstrating that youth involvement in structured, organized activities (e.g. school sports, community clubs) may facilitate positive youth development. We present a theory‐based framework for studying structured activity involvement (SAI) as a context for positive youth development based on two key dimensions: breadth and intensity of involvement. Our main goal is to demonstrate the separability, salience, and developmental significance of these two dimensions. We review three developmental theoretical approaches (identity development, life‐span selection–optimization–compensation theory, and affordances) that support our conceptualization of breadth and intensity as salient and significant dimensions of SAI. We also summarize our recent program of research on SAI demonstrating the separability of breadth and intensity dimensions, which shows links between these dimensions and indicators of positive development. Finally, we discuss how the proposed breadth‐intensity approach could be used to extend research on the linkage between youth SAI and successful development.
