A longitudinal study of children of alcoholics : Predicting young adult substance use disorders, anxiety, and depression

This study tested the specificity of parent alcoholism effects on young adult alcohol and drug abuse/dependence, anxiety, and depression, and tested whether adolescent symptomatology and substance use mediated parent alcoholism effects. Participants were from a longitudinal study in which a target child was assessed in adolescence and young adulthood with structured interview measures (N = 454 families at Time 1). Results showed unique effects of parent alcoholism on young adult substance abuse/dependence diagnoses over and above the effects of other parental psychopathology. There was some evidence of parent alcoholism effects on young adult depression and of maternal alcoholism effects on young adult anxiety, although these were not found consistently across subsamples. Mediational models suggested that parent alcoholism effects could be partially (but not totally) explained by adolescent externalizing symptoms.

Moving Beyond the Keg Party: A Daily Process Study of College Student Drinking Motivations.

Theoretical models of alcohol consumption assert that young adults endorse multiple drinking motives, including drinking to cope with negative experiences and to enhance positive experiences. Social contacts may be important to both pathways. This study applied daily process methodology to determine the relationship between college student drinking in different contexts and daily social contacts and moods. Each afternoon for 3 weeks, 122 undergraduates (43% men, 57% women) logged onto a secure Web site during specified hours to report daily activities, moods, and contacts. Hierarchical linear modeling analyses provided support for motivational models and the context-specific nature of motivated drinking. Individual differences were revealed for each motivation. These findings highlight the importance of studying within-person processes using daily process designs.

Do we know how we cope? Relating daily coping reports to global and time-limited retrospective assessments.

The current study examined the concordance among daily, trait (global retrospective), and time-limited retrospective reports of coping. A sample of 93 adults completed the COPE (C. S. Carver, M. F. Scheier, & J. K. Weintraub, 1989) prior to recording coping with the days most negative event for 30 consecutive days. At the end of daily data collection, participants recalled to what extent they used each of 16 coping strategies over the past 30 days. Whereas findings indicate generally good concordance between daily and time-limited retrospective reports, concordance between global and daily reports was weak. Only limited evidence was found for systematic individual differences in concordance. Time-limited reports appear to be an adequate, though not ideal, method of determining usual patterns of coping with stress.

Daily processes in stress and smoking: effects of negative events, nicotine dependence, and gender.

The author used a multilevel daily process design to examine relations among daily negative events, perceived stress, smoking, and smoking urges. The moderating effects of gender and nicotine dependence were also explored. Fifty-one adult community-residing smokers recorded negative events, perceived stress, cigarette smoking, and urges to smoke 4 times daily for 14 days. Analyses of within-person relations showed that participants smoked more cigarettes and experienced more urges to smoke on occasions with higher numbers of negative events and higher levels of perceived stress. These relations were stronger for men than for women. Nicotine dependence did not interact with events or stress in predicting smoking or urges. These findings build on laboratory studies and cross-sectional surveys by showing that in naturalistic settings, occasions with negative events and perceived stress are associated with smoking and urges to smoke.

Violence in Police Families: Work-Family Spillover

This article uses a path model to examine the relationship between violence exposure and domestic violence among police officers with the expectation that the relationships would be both direct and mediated. The mediation factors included burnout, authoritarian spillover, alcohol use, and department withdrawal. The model was tested through an analysis of data collected from 413 officers. Four mediation chains were identified; the most powerful of these was burnout and authoritarian spillover. Suggestions for future research include understanding violence in the context of unique workplace cultures, classifying violence types, and clarifying how this population defines violence and control.

A Daily Process Examination of the Stress-Response Dampening Effects of Alcohol Consumption

The authors used a daily process design to assess alcohols stress-response dampening (SRD) effects. Moderate to heavy social drinkers (N=100) reported on palmtop computers their alcohol consumption and social context in vivo for 30 days. Participants also reported on their mood states in the late morning and early evening and completed a paper-and-pencil daily diary in which they recorded their negative events. The association between negative events and mood was weaker on days when individuals consumed alcohol prior to the final mood assessment. However, the moderating effect of alcohol on the negative event-mood association was limited to drinking in social situations. Alcohols SRD effects varied as a function of several between-person risk factors.

Probing the effects of individual components in multiple component prevention programs.

Assessing the contributions of individual components in multi-component interventions poses complex challenges for prevention researchers. We review the strengths and weaknesses of designs and analyses that may be useful in answering three questions: (1) Is each of the individual components contributing to the outcome? (2) Is the program optimal? and (3), Through what processes are the components of the program achieving their effects? Factorial and fractional factorial designs in which a systematically selected portion of all possible treatment combinations is implemented are used to address question 1. Response surface designs in which each component is quantitatively scaled are explored in relation to question 2. Mediational analysis, a hybrid of experimental and correlational approaches, is considered in relation to question 3. Design enhancements are offered that may further strengthen some of these techniques. These techniques offer promise of enhancing both the basic science and applied science contributions of prevention research.

A national evaluation of the nighttime and passenger restriction components of graduated driver licensing.

INTRODUCTION The high crash rate of youthful novice drivers has been recognized for half a century. Over the last decade, graduated driver licensing (GDL) systems, which extend the period of supervised driving and limit the novices exposure to higher-risk conditions (such as nighttime driving), have effectively reduced crash involvements of novice drivers. METHOD This study used data from the Fatality Analysis Reporting System (FARS) and the implementation dates of GDL laws in a state-by-year panel study to evaluate the effectiveness of two key elements of GDL laws: nighttime restrictions and passenger limitations. RESULTS Nighttime restrictions were found to reduce 16- and 17-year-old driver involvements in nighttime fatal crashes by an estimated 10% and 16- and 17-year-old drinking drivers in nighttime fatal crashes by 13%. Passenger restrictions were found to reduce 16- and 17-year-old driver involvements in fatal crashes with teen passengers by an estimated 9%. CONCLUSIONS These results confirm the effectiveness of these provisions in GDL systems. Impact on Public Health. States without the nighttime or passenger restrictions in their GDL law should strongly consider adopting them. IMPACT ON INDUSTRY The results of this study indicate that nighttime restrictions and passenger limitations are very important components of any GDL law.

Problem Drinking, Unemployment, and Intimate Partner Violence among a Sample of Construction Industry Workers and their Partners

The purpose of this study is to determine the contribution of male unemployment and each partner’s problem drinking to risk for male-to-female partner violence (MFPV) and female-to-male partner violence (FMPV) among a sample of construction industry workers and their spouses/partners. Participants in the sample (n = 848 couples) completed cross-sectional health behavior surveys. Multivariate logistic regression models of MFPV and FMPV, with adjustment for demographic and psychosocial variables, were developed. Approximately 20% of couples reported MFPV, and 24% reported FMPV. Results indicated that couples in which the male was a problem drinker, and in which the male worker reported being currently unemployed, were at risk for MFPV. Number of months unemployed by the male worker was significantly associated with FMPV, but problem drinking was not associated with this outcome. Male and female impulsivity were significantly associated with risk for MFPV and FMPV, and the male’s report of adverse childhood events was associated with increased likelihood of MFPV. There was no evidence for the effects of unemployment being moderated (exacerbated) by problem drinking. Workplace-based prevention efforts may be a feasible and important strategy to reduce problem drinking and partner violence among high-risk occupational groups.

A daily diary validity test of drinking to cope measures.

Data from 2 daily diary studies of stress, negative affect, and drinking were used to examine the correspondence between global self-reports of drinking to cope (DTC) and within-person stress/negative affect-drinking associations. In Study 1, 83 community-residing drinkers recorded data in nightly booklets on negative events, perceived stress, negative affect, and drinking for 60 consecutive days. In Study 2, 88 community-residing drinkers recorded data on negative events and negative interpersonal exchanges nightly and negative affect and drinking in near-real time on palmtop computers for 30 consecutive days. Both studies showed only modest correspondence between self-reported DTC and between-person differences in within-day, daily, and weekly associations between stress/negative affect and drinking. The findings indicate that individuals who report higher DTC simply may drink across a wider variety of conditions than those who report relatively lower DTC.
