Analysis of variance frameworks in clinical child and adolescent psychology: Advanced issues and recommendations.

Explores more advanced issues that researchers need to consider when using analysis of variance frameworks, building on basic issues for analysis of variance discussed in Jaccard and Guilamo-Ramos (2002). These include (a) using confidence intervals, (b) asserting group equivalence after a nonsignificant result, (c) use of magnitude estimation approaches, (d) sample size and power considerations, (e) outlier analysis, (f) violations of assumptions, and (g) missing data. Suggestions are offered for analytic practices in each of these domains.

Acculturation-Related Variables, Sexual Initiation, and Subsequent Sexual Behavior Among Puerto Rican, Mexican, and Cuban Youth

The relationship among acculturation-related variables, past sexual activity, and subsequent sexual behavior was examined for a sample of Latino youth in the United States over a 12-month period. A subsample from the National Longitudinal Study of Adolescent Health database was analyzed by means of a prospective design. History of sexual intercourse predicted subsequent sexual behavior over the ensuing 12 months. The acculturation-related variables were related to whether an adolescent reported being sexually active at Wave 1 but in a complex fashion. Among recent immigrants, youth from English-speaking homes were less likely to be sexually active than those from Spanish-speaking homes. The opposite was observed for youth who were born in the United States or who had resided in the United States most of their lives.

Adolescent expectancies, parent-adolescent communication and intentions to have sexual intercourse among inner-city, middle school youth.

Background: The incidence and prevalence of pregnancy and sexually transmitted infections among American adolescents remain unacceptably high.Purpose: This research examines adolescent intentions to have sexual intercourse, their expectancies about having sexual intercourse, and maternal communication about the expectancies of engaging in sexual intercourse.Methods: Six hundred sixty-eight randomly selected inner-city middle school students and their mothers completed self-administered questionnaires. Adolescents reported their intentions to have sexual intercourse and the perceived positive and negative expectancies of doing so. Both mothers and adolescents reported on the frequency of communication about these expectancies.Results: Boys reported higher intentions, more positive expectancies, and lower levels of maternal communication than did girls. Expectancies statistically significantly associated with intentions focused on the positive physical, social, and emotional advantages of having sex rather than on concerns about pregnancy and HIV/AIDS. With some exceptions, maternal communication was associated with adolescents-expectancies about engaging in sexual intercourse. However, only modest correlations between maternal and adolescent reports of communication were observed.Conclusions: Results indicate that intervention programs should address the positive expectancies youth have about having sex, not just the threat of pregnancy and HIV/AIDS, and should address potential gender differences in expectancies between boys and girls.

Parental and School Correlates of Binge Drinking Among Middle School Students

OBJECTIVES We examined the prevalence and dynamics of binge drinking among middle school students. METHODS We analyzed data from the National Longitudinal Study of Adolescent Health. The sample was composed of approximately 5300 seventh-and eighth-grade students who were interviewed at 2 points in time. RESULTS Approximately 8% of seventh graders and 17% of eighth graders reported engaging in binge drinking during the past 12 months. These rates varied as a function of school characteristics. Low scores on the parenting variables-communication quality, use of reasoning, and control and supervision-and binge drinking during middle school also were predictive of binge drinking during high school. CONCLUSIONS Binge drinking among middle school students is an important phenomenon that for many students forecasts future binge drinking during high school.

Multiple Regression Analyses in Clinical Child and Adolescent Psychology.

A major form of data analysis in clinical child and adolescent psychology is multiple regression. This article reviews issues in the application of such methods in light of the research designs typical of this field. Issues addressed include controlling covariates, evaluation of predictor relevance, comparing predictors, analysis of moderation, analysis of mediation, assumption violations, outliers, limited dependent variables, and directed regression and its relation to structural equation modeling. Analytic guidelines are provided within each domain.

Binge Drinking Among Latino Youth: Role of Acculturation-Related Variables.

This research examined the relationship between acculturation-related variables and binge drinking behavior among nationally representative samples of Mexican American, Cuban American, and Puerto Rican youth. It explored the relationship between length of residence in the United States, type of language spoken in the home (Spanish vs. English) and binge drinking in each of these subgroups. Results suggest that Latino youths with no prior history of alcohol consumption remain largely unaffected by these acculturation-related variables. Youth with a previous history of alcohol consumption experience greater likelihood of binge drinking as a function of the acculturation-related variables, but the relationships are complex.

Recalling Sexual Partners: The Accuracy of Self-Reports

Accuracy of recall of the number of sexual partners individuals had over a period of one month, three months, six months and one year was studied in a group of 285 young, single, heterosexual adults. Self-reports of the number of partners were obtained on a weekly basis and then compared with recall of behavior over longer time periods that overlapped the weekly measures. For individuals who claimed abstinence or who claimed to be monogamous, accuracy of recall was relatively high, especially at the shorter time frames. Level of education was related to accuracy for claimed abstainers, such that lower levels of education were associated with lower accuracy of recall. Accuracy rates for individuals who reported having multiple sexual partners tended to be lower and were found to be related to one’s propensity to engage in casual sex.

Paternal Influences on Adolescent Sexual Risk Behaviors: A Structured Literature Review

BACKGROUND AND OBJECTIVE: To date, most parent-based research has neglected the role of fathers in shaping adolescent sexual behavior and has focused on mothers. The objective of this study was to conduct a structured review to assess the role of paternal influence on adolescent sexual behavior and to assess the methodological quality of the paternal influence literature related to adolescent sexual behavior. METHODS: We searched electronic databases: PubMed, PsychINFO, Social Services Abstracts, Family Studies Abstracts, Sociological Abstracts, and the Cumulative Index to Nursing and Allied Health Literature. Studies published between 1980 and 2011 that targeted adolescents 11 to 18 years and focused on paternal parenting processes were included. Methodological quality was assessed by using an 11-item scoring system. RESULTS: Thirteen articles were identified and reviewed. Findings suggest paternal factors are independently associated with adolescent sexual behavior relative to maternal factors. The most commonly studied paternal influence was emotional qualities of the father-adolescent relationship. Paternal communication about sex was most consistently associated with adolescent sexual behavior, whereas paternal attitudes about sex was least associated. Methodological limitations include a tendency to rely on cross-sectional design, nonprobability sampling methods, and focus on sexual debut versus broader sexual behavior. CONCLUSIONS: Existing research preliminarily suggests fathers influence the sexual behavior of their adolescent children; however, more rigorous research examining diverse facets of paternal influence on adolescent sexual behavior is needed. We provide recommendations for primary care providers and public health practitioners to better incorporate fathers into interventions designed to reduce adolescent sexual risk behavior.

HIV/AIDS and Tourism in the Caribbean: An Ecological Systems Perspective

The Caribbean has the highest HIV rates outside of sub-Saharan Africa. In recent decades, tourism has become the most important Caribbean industry. Studies suggest that tourism areas are epicenters of demographic and social changes linked to HIV risk, such as transactional sex, elevated alcohol and substance use, and internal migration. Despite this, no formative HIV-prevention studies have examined tourism areas as ecologies that heighten HIV vulnerability. HIV/AIDS research needs to place emphasis on the ecological context of sexual vulnerability in tourism areas and develop multilevel interventions that are sensitive to this context. From our review and integration of a broad literature across the social and health sciences, we argue for an ecological approach to sexual health in Caribbean tourism areas, point to gaps in knowledge, and provide direction for future research.

Dual ethnicity and depressive symptoms: Implications of being black and Latino in the United States

This study investigated the expression of depressive symptoms in adolescents who are of Afro-Latino descent. Levels of expression of depressive symptoms were compared for four groups of adolescents in Grades 7 through 12 residing in the United States: European Americans, African Americans, Latinos, and Afro-Latinos. One hypothesis is that Afro-Latinos should exhibit higher levels of depressive symptoms than either African Americans or Latinos by virtue of being double minorities. An alternative hypothesis is that Afro-Latino youth will show lower levels of depressive symptomology because of their access to a broader repertoire of cultural resources when faced with stress and depression-inducing events. Results indicated that Afro-Latino females tended to exhibit higher levels of depressive symptoms than those of the other ethnic groups. Across all ethnic groups, adolescent females tended to show higher levels of depressive symptoms than adolescent males and older adolescents tended to show higher levels of depression than younger adolescents.
