Daily covariation of sleep quantity and quality with affective, stressful, academic, and social experiences were observed in a sample of Canadian 17-19-year-olds in their first year of university. Participants (N 5 191) completed web-based checklists for 14 consecutive days during their first semester. Multilevel models predicting sleep quantity and quality from daily experiences indicated that more time on schoolwork, expecting a test, and alcohol use predicted less sleep whereas socializing predicted more sleep. More positive affect and no alcohol use predicted better sleep quality. Models predicting daily experiences from sleep the night before indicated that less sleep preceded increases in negative affect, decreases in schoolwork time, and a higher likelihood of socializing. Better sleep quality preceded increased positive affect, decreased negative affect and stress, and less time on schoolwork. These data are informative for understanding relations between sleep and daily experiences as they occur naturally in first-year university students.

The relationship between sexual recidivism and posttreatment denial and minimization was examined among 436 sex offenders followed up for an average period of more than 5 years. Treatment completion status and psychopathic traits, both established predictors of sexual recidivism also associated with denial and minimization, were included in survival analyses to remove their confounding influence on the focal relationships. The potential role of actuarial risk as a moderating variable was also investigated. A dichotomous variable reflecting denial and minimization failed to predict sexual recidivism. However, among a subset of 102 sex offenders who received no additional treatment after completing an initial program, the interaction between actuarial risk and scores on a continuous measure of minimization predicted sexual recidivism. Implications for assessment, particularly the need to move beyond dichotomous operationalizations of denial and minimization, and treatment were discussed.

This research applied a lifespan developmental framework to the study of sexual behavior among late adolescents by examining monthly covariations of penetrative and oral sex with positive and negative affect across the first year of university. Participants were 177 Canadian students who completed baseline questionnaires, followed by six monthly, web-based questionnaires assessing sexual behaviors and affect. Multilevel analyses revealed an average positive relation between oral sex and positive affect. Of six variables, five predicted individual differences in covariation between sex and affect: psychosocial maturity (immature and semi-mature status), attitudes toward sex, prior sexual experience, and living situation. During months when participants reported sexual behavior, psychosocially mature students reported more positive affect than did less mature students; students with more permissive attitudes reported more positive affect than did students with less permissive attitudes; students with no penetrative sexual experience reported more positive affect than students who had penetrative sexual experience; and living away from parents was associated with less negative affect. Implications for further study of sexual behavior from a developmental perspective are discussed.
