The Influence of Parental Communication and Perception of Peers on Adolescent Sexual Behavior.

The authors used the theory of planned behavior to examine the influence of parents and peers on early adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse. Adolescents (N = 212) provided self-reports of their perception of parent and peer attitudes regarding sexual behavior. The authors used bivariate and regression analyses to examine the relation between parent and peer attitudes with adolescent sexual attitudes, self-efficacy to limit sexual behavior, and behavioral intentions to have vaginal intercourse.

Smoking on school property as a risk factor for substance use among adolescent smokers.

Illness Beliefs Regarding the Causes of Diabetes among Latino College Students.

This study examined the validity of the Klonoff and Landrine (1994) illness-belief scale when applied to Latino college students (n=156; 34% male, 66% female) at high-risk for future diabetes onset. Principal factor analysis yielded four significant factors - emotional, folk-beliefs, punitive, gene/hereditary - which accounted for 64.5% of variance and provided a culturally-relevant Latino perspective of the causes of diabetes.

Sexual risk behavior among early initiators of sexual intercourse.

The aim of this study was to examine sexual risk behavior among adolescents in the United States classified as early initiators of sexual intercourse. Secondary analyses were carried out with data from the 2007 Youth Risk Behavior Survey (n=14,041). Only adolescents 16-18 years old who reported being sexually experienced were selected for analyses (n=5315, 48% female).

Evaluation of a school-based intervention for HIV/AIDS prevention among Belizean adolescents.

The purpose of this study was to evaluate the impact of a cognitive-behavioral peer-facilitated school-based HIV/AIDS education program on knowledge, attitudes and behavior among primary and secondary students in Belize. Students (N = 150) were recruited from six schools in Belize City. A quasi-experimental research design was used to assess the impact of a 3-month intervention.

Indices of lifetime polydrug use among adolescents.

The functional equivalency for three indices of lifetime polydrug use was examined in a sample of adolescents (N = 794). The following indices were included in analyses: (a) a count of lifetime self-report of substances used; (b) an index weighted by the severity of the substances used; and (c) a hierarchical index of substance use. Analyses for each index was conducted twice with abstinent youth (no report of substances over their lifetime) included and excluded from analyses.

Validating the effects of social desirability on self-reported condom use behavior among commercial sex workers.

Most studies on the transmission of HIV depend upon self-reports of risky behaviors. This study examines if there is social desirability bias with respect to self-reported condom use behavior, assesses the reliability of a self-reported condom use scale, and validates the self-reported findings with clinical sexually transmitted infection (STI) diagnosis for commercial sex workers (N = 1,383) in the Philippines. The reliability of the condom use scale is .

Correlates and implications for agreeableness in children.

This study is an examination of the relationship between agreeableness and other constructs related to children's social relationships. Third through 6th graders (N = 76; 46 boys, 30 girls) completed self-reports on agreeableness (based on the adult version of the NEO Personality Inventory Manual; Costa & McCrae, 1985), social skills (Social Skills Rating System for Children; Gresham & Elliot, 1991), empathy (Feshbach, 1990) and trust (Children's Trust Scale; Imber, 1973). Using multiple regression, agreeableness was predicted by social skills, empathy, and trust for girls.

Correlates of HIV risk among Ecuadorian adolescents.

The purpose of this study was to examine the relationship of HIV knowledge, demographics, and psychosocial factors with HIV risk behavior among high school students (N = 805) in urban and rural regions of Ecuador. Forty-three percent of the participants reported being sexually experienced. Of the sexually experienced participants, 50% reported never using condoms for intercourse, and 70% did not use condoms at last intercourse.
