Daily physical activity and alcohol use among young adults.

Evidence suggests that physical activity and alcohol use are positively related among young adults. Two studies have examined daily relations, and results have shown conflicting findings. We examined relations between physical activity and alcohol use at both within- and between-individual levels and investigated moderators of the relation at both levels. 269 college students wore accelerometers to collect physical activity data over a 2-week period. At the end of each day, they indicated whether or not they drank alcohol. Multilevel logistic regression indicated neither within- nor between-subject relations were statistically significant. Positive affect, negative affect, and drinking motives moderated these relations at the between-subject level. Contrary to previous research, we did not observe a relation between physical activity and alcohol use at the daily level. Unique features of the current study suggest next steps for future research examining the perplexing PA-alcohol relation in this population.

Construct validity of the Comprehensive Assessment of Psychopathic Personality (CAPP) Lexical Rating Scale.

The current study investigated the internal structure and validity of a self-rating form for the Comprehensive Assessment of Psychopathic Personality (CAPP) model in a large sample consisting of American (n = 463) and Australian (n = 94) undergraduates along with a U.S. community sample (n = 182). More specifically, we explored the factor structure of the CAPP Lexical Rating Scale and examined its associations with measures of psychopathy, antisocial behavior, and broad pathological personality traits. Neither exploratory factor analysis nor bass-ackward analyses supported the six proposed domains. Exploratory factor analysis supported a three-factor structure, generally representing the behavioral, interpersonal, and affective domains of psychopathy. Correlations with conceptually relevant external criteria demonstrated the identified three-factor structure was not superior to the six proposed rational domains with respect to construct validity. Symptom-level analyses supported the use of CAPP symptom as measures of individual symptoms with good convergent validity. Overall, the current study supports the construct validity of the CAPP model, and the Lexical Rating Scale in particular, but more research is needed to further explore the optimal structure of the model.
