The relationship between self-perception of physical attractiveness and sexual bullying in early adolescence.

The relationship between self-perception of physical attractiveness and four measures of sexual bullying behavior (victimization, perpetration, having friends who sexually bully, and observation of sexual bullying among peers at school) was examined in a sample of 396 middle school age students. Students who perceived themselves to be more physically attractive than their peers reported sexually bullying others more, being sexually bullied by others more, observing more sexual bullying, and having more friends who sexually bully others than did students who perceived themselves as average looking. In addition, males who perceived themselves to be less physically attractive than their peers reported being victimized more and reported observing more sexual bullying in the school environment. These findings highlight the importance of physical attractiveness in the early initiation of sexual harassment. Implications for future research and interventions with early adolescents are discussed.

On the Psychometric Study of Human Life History Strategies: State of the Science and Evidence of Two Independent Dimensions

This article attends to recent discussions of validity in psychometric research on human life history strategy (LHS), provides a constructive critique of the extant literature, and describes strategies for improving construct validity. To place the psychometric study of human LHS on more solid ground, our review indicates that researchers should (a) use approaches to psychometric modeling that are consistent with their philosophies of measurement, (b) confirm the dimensionality of life history indicators, and (c) establish measurement invariance for at least a subset of indicators. Because we see confirming the dimensionality of life history indicators as the next step toward placing the psychometrics of human LHS on more solid ground, we use nationally representative data and structural equation modeling to test the structure of middle adult life history indicators. We found statistically independent mating competition and Super-K dimensions and the effects of parental harshness and childhood unpredictability on Super-K were consistent with past research. However, childhood socioeconomic status had a moderate positive effect on mating competition and no effect on Super-K, while unpredictability did not predict mating competition. We conclude that human LHS is more complex than previously suggested—there does not seem to be a single dimension of human LHS among Western adults and the effects of environmental components seem to vary between mating competition and Super-K.

Immediate Survival Focus: Synthesizing Life History Theory and Dual Process Models to Explain Substance Use

Researchers have recently applied evolutionary life history theory to the understanding of behaviors often conceived of as prosocial or antisocial. In addition, researchers have applied cognitive science to the understanding of substance use and used dual process models, where explicit cognitive processes are modeled as relatively distinct from implicit cognitive processes, to explain and predict substance use behaviors. In this paper we synthesized these two theoretical perspectives to produce an adaptive and cognitive framework for explaining substance use. We contend that this framework provides new insights into the nature of substance use that may be valuable for both clinicians and researchers.

Differentiating Characteristics and Needs of Minority Grandparent Caregivers

Abstract Data collected over a three-year period compared two groups of African American grandparent caregivers with a group of European American grandparents who were raising their grandchildren. Gender, marital status, and household income differentiated minority from nonminority participants. Statistically significant differences among certain of the demographic variables between the two groups of African American grandparents were also found. Practical implications of the results for research and practice are discussed through illustrating differences in advocacy needs and agenda-making between two grandparent caregiver support groups.

SUMMER AND SCHOOL-TERM YOUTH EMPLOYMENT: ECOLOGICAL AND LONGITUDINAL ANALYSES

The effects of summer versus school-year employment on self-esteem, peer relationships, and family social climate were investigated in a sample of 135 adolescents. Students were assessed the summer before entrance into high school and during the second semester of high school, using a longitudinal design. Cross-sectional findings indicated that, during the summer, 52 workers possessed higher self-esteem than 79 nonworkers. Longitudinal analysis indicated that 10 girls who worked only during the school term reported increases in both stress and activity with peers. At our final assessment, the families of 49 students who did not work at either time had become more conflicted and less cohesive than families of all other students. The developmental implications of these results are discussed.

Life History Strategy and Young Adult Substance Use

This study tested whether life history strategy (LHS) and its intergenerational transmission could explain young adult use of common psychoactive substances. We tested a sequential structural equation model using data from the National Longitudinal Survey of Youth. During young adulthood, fast LHS explained 61% of the variance in overall liability for substance use. Faster parent LHS predicted poorer health and lesser alcohol use, greater neuroticism and cigarette smoking, but did not predict fast LHS or overall liability for substance use among young adults. Young adult neuroticism was independent of substance use controlling for fast LHS. The surprising finding of independence between parent and child LHS casts some uncertainty upon the identity of the parent and child LHS variables. Fast LHS may be the primary driver of young adult use of common psychoactive substances. However, it is possible that the young adult fast LHS variable is better defined as young adult mating competition. We discuss our findings in depth, chart out some intriguing new directions for life history research that may clarify the dimensionality of LHS and its mediation of the intergenerational transmission of substance use, and discuss implications for substance abuse prevention and treatment.

Analysis of activities of school counselors.

369 school counselors in Kentucky completed a survey of time allocated to 17 different activities. The allocation of time per activity differed across level of school. Developmental implications of the findings are discussed.

The Structure and Validity of the Multidimensional Social Support Questionnaire.

The factor structure and concurrent validity of the Multidimensional Social Support Questionnaire, a brief measure of perceived social support for use with adolescents, was examined. Findings suggest that four dimensions of perceived social support may yield more information than assessments of the unitary construct of support.
