Sex-role orientation,behavioral adaptability and personal adjustment

Bem's Sex-Role Inventory was used to classify 111 college men and women into masculine, feminine, androgynous, and undifferentiated sex-role categories. Subjects were tested for emotional expressivity (feminine task), assertiveness (masculine task), and personal integration. Sex typed and cross-sex typed subjects performed well only on those tasks which were congruent with their measured sex role. Androgynous subjects exhibited the greatest behavioral adaptability, performing well on both masculine and feminine tasks; undifferentiated subjects performed poorly on both tasks, but particularly so on sex-reversed tasks. Thus, behavioral flexibility was shown to derive from strong identifications with both masculine and feminine roles (androgyny) rather than from a simple lack of identification with either role. In addition, contrary to previous findings that masculine-typed women are better adjusted than feminine-typed women, androgynous and sex typed subjects both scored high in personal integration, with cross-sex typed subjects of both sexes scoring as low as undifferentiated subjects.     

Reciprocal relations between adolescent substance use and delinquency: a longitudinal latent variable analysis

Reciprocal relations between self-reported substance use and delinquency were examined through the analysis of 4-wave panel data collected from 1,218 high school students. A longitudinal, latent-variable framework was used to investigate interrelationships between changing patterns of generalized involvement in these 2 problem behaviors, while simultaneously accounting for specificity in drug use (e.g., marijuana use) and delinquency (e.g., theft). Analyses revealed that a model of bidirectional effects between polysubstance use and general delinquency was plausible for boys but not for girls. For boys, the effect of delinquency on substance use was small but consistent over time, whereas the effect of substance use on delinquency was larger but restricted to the earlier waves of the study. Implications for the question of whether or not substance use and delinquency have causal connections are discussed.     

Factor structure and psychometric properties of the Brief Symptom Inventory-18 in women: a MACS approach to testing for invariance across racial/ethnic groups

This study used data from 3 sites to examine the invariance and psychometric characteristics of the Brief Symptom Inventory-18 across Black, Hispanic, and White mothers of 5th graders (N = 4,711; M = 38.07 years of age, SD = 7.16). Internal consistencies were satisfactory for all subscale scores of the instrument regardless of ethnic group membership. Mean and covariance structures analysis indicated that the hypothesized 3-factor structure of the instrument was not robust across ethnic groups. It provided a reasonable approximation to the data for Black and White women but not for Hispanic women. Tests for differential item functioning (DIF) were therefore conducted for only Black and White women. Analyses revealed no more than trivial instances of nonuniform DIF but more substantial evidence of uniform DIF for 3 of the 18 items. After having established partial strong factorial invariance of the instrument, latent factor means were found to be significantly higher for Black than for White women on all 3 subscales (somatization, depression, anxiety). In conclusion, the instrument may be used for mean comparisons between Black and White women.     

Living with Ill-Health in Older Age: The Role of a Resilient Personality

This paper tests the hypothesis that a resilient personality moderates the impact of ill-health on subjective well-being. A cross-sectional survey drew a random sample of 1,847 people from England, Wales and Scotland aged between 50 and 90. Participants were interviewed face-to-face in their own homes. This paper examines demographic data, life satisfaction, psychological resources and ill-health. The direct and moderating effects were analysed using the method of multiple regression. Significant main effects of resilience and ill-health on life satisfaction were found in all of the age-groups. In three of these (60–69, 70–79 and 80–90) the addition of the interaction term was associated with a significant increase in the size of the effect, indicating a resilient self moderated the negative effect of ill-health on subjective well-being. Resilient resources can be a valuable mechanism for maintaining well-being and understanding differential resistance to, and recovery from ill-health in later life.     

Does a Booster Intervention Augment the Preventive Effects of an Abbreviated Version of the Coping Power Program for Aggressive Children?

Booster interventions have been presumed to be important methods for maintaining the effects of evidence-based programs for children with behavioral problems, but there has been remarkably little empirical attention to this assumption. The present study examines the effect of a child-oriented booster preventive intervention with children who had previously received an abbreviated version (24 child sessions, 10 parent sessions) of the Coping Power targeted prevention program. Two hundred and forty-one children (152 boys, 89 girls) were screened as having moderate to high levels of aggressive behavior in 4th grade, then half were randomly assigned to receive the abbreviated Coping Power program in 5th grade, and half of the preventive intervention children were then randomly assigned to a Booster condition in 6th grade. The Booster sessions consisted of brief monthly individual contacts, and were primarily with the children. Five assessments across 4 years were collected from teachers, providing a three-year follow-up for all children who participated in the project. Results indicated that the abbreviated Coping Power program (one-third shorter than the full intervention) had long-term effects in reducing children’s externalizing problem behaviors, proactive and reactive aggression, impulsivity traits and callous-unemotional traits. The Booster intervention did not augment these prevention effects. These findings indicate that a briefer and more readily disseminated form of an evidence-based targeted preventive intervention was effective. The findings have potential implications for policy and guidelines about possible intervention length and booster interventions.     

The Abbreviated Dimensions of Temperament Survey: Factor Structure and Construct Validity Across Three Racial/Ethnic Groups

The factor structure, reliability, and construct validity of an abbreviated version of the Revised Dimensions of Temperament Survey (DOTS–R) were evaluated across Black, Hispanic, and White early adolescents. Primary caregivers reported on 5 dimensions of temperament for 4,701 children. Five temperament dimensions were identified via maximum likelihood exploratory factor analysis and were labeled flexibility, general activity level, positive mood, task orientation, and sleep rhythmicity. Multigroup mean and covariance structures analysis provided partial support for strong factorial invariance across these racial/ethnic groups. Mean level comparisons indicated that relative to Hispanics and Blacks, Whites had higher flexibility, greater sleep regularity, and lower activity. They also reported higher positive mood than Blacks. Blacks, relative to Hispanics, had higher flexibility and lower sleep regularity. Construct validity was supported as the 5 temperament dimensions were significantly correlated with externalizing problems and socioemotional competence. This abbreviated version of the DOTS–R could be used across racial/ethnic groups of early adolescents to assess significant dimensions of temperament risk that are associated with mental health and competent (healthy) functioning.     

Mediators of Neighborhood Influences on Externalizing Behavior in Preadolescent Children

This study tested a mediation model of neighborhood influences on children’s externalizing behavior. In the proposed model, neighborhood disadvantage, ethnic heterogeneity, and low residential stability affect children’s behavior indirectly through their impact on neighborhood social processes, which in turn influence parenting and deviant peer affiliations. A community sample of 704 preadolescents (76% African American, 22% Caucasian) and their parents and teachers provided information for the study. Neighborhood concentrated poverty, derived from the 2000 U.S. Census, was positively associated with children’s externalizing behavior. This effect was fully mediated by neighborhood social processes and parenting quality, while deviant peer affiliations made independent contributions to problem behavior. The final mediation model explained children’s externalizing behavior equally well across gender and ethnicity, suggesting the presence of universal processes.     

Predictive Value of Informant Discrepancies in Reports of Parenting: Relations to Early Adolescents’ Adjustment

Research has demonstrated a lack of agreement between parent and child reports across a range of parent and child variables. These discrepancies hinder the interpretation of research findings as well as diagnostic and treatment decisions in clinical practice. The current study examined the hypothesis that discrepancies between parent and child reports of parenting can be useful as predictors of future child outcomes. The participants included 559 early adolescents and their primary caregivers (79% African American, 21% Caucasian). Both respondents provided information on parental nurturance, harsh discipline and inconsistent discipline. A year later, information of adolescents’ internalizing problems, externalizing problems, and social competence was collected. Structural equation modeling revealed that parent-child discrepancies in parenting reports could be explained by a latent factor which was a significant predictor of child internalizing problems and social competence, but not of externalizing problems, after adjusting for initial internalizing and externalizing problems. The three models applied across gender and ethnicity.     

Fluoxetine inhibits corticotropin-releasing factor (CRF)-induced behavioural responses in rats

Corticotropin-releasing factor (CRF) is a potent neuromodulator of stress-related behaviour but the neural mechanisms underlying these effects are not clear. Studies were designed to test the hypothesis that CRF-induced behavioural arousal involves interactions with brainstem serotonergic systems. To examine interactions between CRF and serotonergic systems in the regulation of behaviour, CRF (1 microg, intracerebroventricular (i.c.v.)) or vehicle was infused in the presence or absence of the selective serotonin re-uptake inhibitor fluoxetine (0, 0.1, 1 or 10 mg/kg, intravenous (i.v.)). Fluoxetine was used at these doses because it is known to decrease serotonin cell firing rates while increasing extracellular serotonin concentrations in select forebrain regions. We then measured behavioural, neurochemical and endocrine responses. CRF increased locomotion and spontaneous non-ambulatory motor activity (SNAMA) in the home cages. Fluoxetine decreased tissue 5-hydroxyindoleacetic acid concentrations, a measure of serotonin metabolism, in specific limbic brain regions of CRF-treated rats (nucleus accumbens shell region, entorhinal cortex, central nucleus of the amygdala). Furthermore, fluoxetine inhibited CRF-induced SNAMA. CRF and fluoxetine independently increased plasma corticosterone concentrations, but the responses had distinct temporal profiles. Overall, these data are consistent with the hypothesis that CRF-induced facilitation of behavioural activity is dependent on brainstem serotonergic systems. Therefore, fluoxetine may attenuate or alleviate some behavioural responses to stress by interfering with CRF-induced responses.
