On the Psychometric Study of Human Life History Strategies.

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.

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.
