Effectiveness of school-based prevention and intervention programs for children and adolescents with emotional disturbance: A meta-analysis

The present study evaluated the effectiveness of school-based prevention and intervention programs for children and adolescents at-risk for and with emotional disturbance. Published outcome studies (k = 29) from December, 1988, to March, 2006, including 1405 children and adolescents were reviewed. Each investigation was coded on several variables describing the child, parent, and teacher samples, as well as reported outcome results. The overall mean weighted effect size was 1.00 at post-test and 1.35 at follow-up. Mean weighted ESs were 0.42 for between-subjects design studies, 0.87 for within-subjects design studies, and 1.87 for single-subject design studies. Prevention programs yielded a mean weighted ES of 0.54 and intervention programs produced a mean weighted ES of 1.35. Findings for specific outcome foci are presented and implications are discussed.     

Mapping Gray’s BIS and BAS constructs onto Factor 1 and Factor 2 of Hare’s Psychopathy Checklist – Revised

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.     

Response perseveration in psychopathic women.

Recent attempts to validate the Psychopathy Checklist-Revised (PCL-R) as a measure of psychopathy in female offenders have been limited by a failure to examine laboratory correlates of the syndrome. We assessed 112 incarcerated women by using the PCL-R and examined their performance on a card perseveration task that has been used to demonstrate response perseveration in psychopathic men. Contrary to prediction, psychopathic women did not perseverate responding when the PCL-R was used either dimensionally or categorically. The authors discuss the implications of the results for the PCL-R and for female psychopathy more generally.     

The relative importance of gender role attitudes to male and female attitudes toward lesbians

Previous studies suggest that gender role attitudes, parental attitudes, authoritarianism, religiosity, contact with homosexuals, and exposure to educational influences are associated with attitudes toward homosexuals. Few studies have been conducted on attitudes toward lesbians specifically. This study investigated the pattern of predictors for male and female attitudes toward lesbians. The regression analysis on males revealed that gender role attitudes were the only significant predictor, while gender role attitudes, parental attitudes, authoritarianism, and educational and media influences made a contribution to female attitudes toward lesbians. Despite more liberal gender role attitudes expressed by female respondents, there was no difference between male and female attitudes toward lesbians. This finding and the additional contribution to female attitudes toward lesbians made by the other predictors besides gender role attitudes suggests that the female respondents' development of attitudes toward lesbians is a product of a wider array of variables, with gender role attitudes playing a more central role in the development of male attitudes toward lesbians. Nevertheless, the importance of gender role attitudes to both male and female attitudes toward lesbians suggests that stratification by sex might be an underlying variable for both gender role attitudes and attitudes toward lesbians.The author wishes to thank Esther Sales, Gary Koeske, Barbara Shore, and Randi Koeske for their guidance with the research study.

The relationship between daily events and mood: The mood measure may matter

Measures of daily mood have been used as immediate indicators of the effects of the psychosocial environment, the latter concept often measured by daily events. We examined the prediction of two measures of daily mood, the Positive and Negative Affect Schedule (PANAS) and Nowlis Mood Adjective Checklist (MACL), by daily desirable and undesirable events and by day of the week. Unlike prior studies, the event assessment and type of subjects studied (community residents) were the same in both studies, allowing an attribution of differential associations between the two mood scales and either daily events or day of the week to the different mood measures. The mood measures had similar and expected associations with daily events, although the MACL scale generally had stronger associations with events. Surprisingly, the pattern of day of the week effects for positive, yet not negative, mood were different for the two mood measures. Consistent with the weekend's increase in desirable daily events, MACL positive affectincreased on weekends, relative to weekdays, whereas PANAS positive mooddecreased on weekends. Also, for both positive and negative affect scales, the MACL scales had stronger associations with day of week than the PANAS scales. These results suggest caution in the choice of mood measure to use in studies of daily events and pose questions about the meaning of these mood measures.This work was supported, in part, by grant MH39234 from NIMH.

Hostile attributional biases in severely aggressive adolescents

Adolescent boys (N = 128) from a maximum security prison for juvenile offenders were administered a task to assess hostile attributional biases. As hypothesized, these biases were positively correlated with undersocialized aggressive conduct disorder (as indicated by high scores on standardized scales and by psychiatric diagnoses), with reactive-aggressive behavior, and with the number of interpersonally violent crimes committed. Hostile attributional biases were found not to relate to nonviolent crimes or to socialized aggressive behavior disorder. These findings held even when race and estimates of intelligence and socioeconomic status were controlled. These findings suggest that within a population of juvenile offenders, attributional biases are implicated specifically in interpersonal reactive aggression that involves anger and not in socialized delinquency.     

Evaluating the construct validity of psychopathy in black and white male inmates: three preliminary studies

Although Black inmates represent almost half the population of United States prisons and have been included in several studies of psychopathy, there appear to be no published studies to date addressing the validity of the psychopathy construct in Black inmates. Three studies were conducted to assess the validity of the construct in Black male inmates using Hare's Psychopathy Checklist (PCL). In Study 1, we examined the internal structure of the PCL and the relation of checklist scores to several constructs relevant to psychopathy. We observed differences between Blacks and Whites in the distribution of psychopathy scores, in the relation of psychopathy to measures of impulsivity, and in the congruence of the underlying factor structure of the PCL. In Study 2, Black psychopaths were found to manifest a pattern of passive avoidance deficits similar but not identical to that reported for White psychopaths in Newman and Kosson's study. Study 3 demonstrated that psychopaths of both races receive more criminal charges in a wider variety of offense categories than do nonpsychopaths. The psychopathy construct appears tentatively applicable to Blacks, although its components may be somewhat different than for Whites.     

The effects of nodality on the formation of equivalence classes

A four-member equivalence class (A → B → C → D) can be formed by training AB, BC, and CD. The nodal stimuli, B and C, mediate all of the derivative (transitive and equivalence) relations in the class. The derivative relations AC, CA, BD, and DB are separated by one node, whereas AD and DA are separated by two nodes. How do the number of nodes that separate the stimuli in a derivative relation influence the induction of stimulus control exerted by that relation? Seven college students learned two four-member classes made up of nonsense syllables. After training, all derivative relations were presented repeatedly without informative feedback. Stimulus control exerted by each derivative relation was assessed concurrently. For the 7 subjects, control exerted by the derivative relations increased gradually with repeated presentations. With 6 of the 7 subjects, the one-node relations exerted more control than the two-node relations during the process. However, the disparity between the one- and two-node relations decreased with repeated presentations. Eventually, all derivative relations exerted complete control. The control exerted by derivative relations during induction was inversely related to the number of nodes separating the terms in the derivative relations. These results demonstrate that nodal distance is a determinant of the relatedness of stimuli in equivalence classes. The findings are discussed in terms of remote association, semantic memory networks, and the study of transitive inference.
