Religious Activity and Risk Behavior Among African American Adolescents: Concurrent and Developmental Effects

This study examines how religious activity is associated with risk behaviors, concurrently and developmentally among urban African American adolescents. Seven hundred and five African American youths were interviewed annually during high school. Retention rates for the study exceeded 90%. Frequency of religious activity, sexual intercourse, and alcohol, cigarette, and marijuana use were assessed at each wave. Growth curve analyses found negative concurrent associations between religious activity and each of the four risk behaviors. The developmental effects of religious activity varied by gender. Higher levels of religious activity in 9th grade predicted smaller increases in marijuana use among males and cigarette use among females. In addition, larger decreases in religious activity during high school were associated with greater increases in alcohol use among males and sexual intercourse among females. During high school, religious activity limits the development of certain types of risk behavior among African American youth, even after controlling for reciprocal effects.     

Onset of frailty in older adults and the protective role of positive affect

The aim of this study was to examine the longitudinal association between positive affect and onset of frailty for 1,558 initially nonfrail older Mexican Americans from the Hispanic Established Populations for Epidemiological Studies of the Elderly database. The incidence of frailty increased 7.9% during the 7-year follow-up period. High positive affect was found to significantly lower the risk of frailty. Each unit increase in baseline positive affect score was associated with a 3% decreased risk of frailty after adjusting for relevant risk factors. Findings add to a growing positive psychology literature by showing that positive affect is protective against the functional and physical decline associated with frailty.     

Neuropsychological executive functioning in children at elevated risk for alcoholism: findings in early adolescence

One component of individual risk for alcoholism may involve cognitive vulnerabilities prodromal to alcoholism onset. This prospective study of 198 boys followed between 3 and 14 years of age evaluated neurocognitive functioning across three groups who varied in familial risk for future alcoholism. Measures of intelligence, reward-response, and a battery of neuropsychological executive and cognitive inhibitory measures were used. Executive functioning weaknesses were greater in families with alcoholism but no antisocial comorbidity. IQ and reward-response weaknesses were associated with familial antisocial alcoholism. Executive function effects were clearest for response inhibition, response speed, and symbol-digit modalities. Results suggest that executive deficits are not part of the highest risk, antisocial pathway to alcoholism but that some executive function weaknesses may contribute to a secondary risk pathway.     

Do college students drink more than their non-college-attending peers? Evidence from a population-based longitudinal female twin study

The association of college attendance with alcohol use and alcohol use disorders was examined in a population-based young adult female twin sample identified from a systematic search of birth records. College-attending women consumed a larger overall volume of alcohol than did their non-college-attending peers, but they were not more likely to be diagnosed with an alcohol use disorder. Significant associations between college attendance and alcohol involvement were probed using 3 different complementary research designs: multivariate cross-sectional analyses, longitudinal analyses of the precollege and college years, and cotwin-control analyses of twin pairs discordant for attending college. Although demographic and lifestyle characteristics accounted for most or all of the association between college attendance and alcohol involvement, there was 1 aspect of drinking behavior, occasionally consuming large quantities of alcohol, that remained significantly associated with college attendance even after controlling for these characteristics or for genetic and family background factors. These results are consistent with the conclusion that some aspect of the college experience may be an important environmental risk factor for this pattern of drinking among young adults.     

NEO-PI-R neuroticism scores in substance-dependent outpatients: internal consistency and self-partner agreement

We evaluated internal consistency reliabilities and self-partner agreement on Revised NEO Personality Inventory (Costa & McCrae, 1992) Neuroticism (N) domain and facet scores (anxiety, angry hostility, depression, self-consciousness, impulsiveness, vulnerability) in a sample of 48 substance-dependent outpatients. Low internal consistency was seen for self-rated impulsiveness (alpha =.36). Agreement between self and partner reports was low for impulsiveness (.22) and vulnerability (.24) and was modest for the remaining facets of N (.31 to.34) and the N domain score (.31).     

Comparing learning environments in U.S. military officer education: a brief replication

A 2003 comparative study on learning environments at two military officer training sites was replicated using different methodology. Satisfaction with learning environment and with administrative inprocessing was higher at Fort Leavenworth than at Fort Dix. Most students expressed a preference for Fort Leavenworth. Satisfaction with institutional support and educational facilities appears to influence perceived satisfaction with a learning environment and with preference for training sites among senior military officers.     

Combining probability values from independent permutation tests: a discrete analog of Fisher's classical method

Permutation tests are based on all possible arrangements of observed data sets. Consequently, such tests yield exact probability values obtained from discrete probability distributions. An exact nondirectional method to combine independent probability values that obey discrete probability distributions is introduced. The exact method is the discrete analog to Fisher's classical method for combining probability values from independent continuous probability distributions. If the combination of probability values includes even one probability value that obeys a sparse discrete probability distribution, then Fisher's classical method may be grossly inadequate.     

Minority adolescents and substance use risk/protective factors: a focus on inhalant use

Despite the fact that inhalant use is a growing problem among youth in the United States, relatively little attention has been paid to the demographic and social factors related to its use. This study used data from a household survey of adolescents in Washington state, and found that race/ethnicity was a strong predictor of lifetime prevalence of inhalant use, with Native-American youth being particularly likely to use inhalants. Comparing the age at initiation of inhalant use to other legal and illegal substances, we found that cigarettes and inhalants showed the lowest age at initiation. We conducted logistic regressions on lifetime prevalence of inhalant use, and compared these models to other substances. In general, we found that attachment to parents. parents' drug use, and school attachment were strong predictors of lifetime use of marijuana, alcohol, and inhalants. However, while peer drug use was a strong predictor of marijuana and alcohol use, it was not a significant predictor of adolescents' use of inhalants. Our final set of analyses included inhalant use in regression models predicting other problem behaviors: these analyses demonstrated that inhalant use was a strong predictor of involvement in problem behavior.     

What is the right thing at the right time? Interactions between stages and processes of change among smokers who make a quit attempt.

C. A. Perz, C. C. DiClemente, and J. P. Carbonari (1996) claim support for the transtheoretical model notion that success in smoking cessation involves doing the right thing at the right time: emphasising experiential change processes during the contemplation and preparation stages and shifting to behavioral process activities during action. A key methodological limitation of Perz et al. was their failure to control for stage of change, a measure that has been shown to be predictive of cessation. This study replicates the prospective findings of Perz et al. in a different data set, then controls for stage of change when it is predictive of cessation, and finds that the measures of "appropriate" change process use developed by Perz et al. no longer predict cessation. The authors conclude that stage of change, in particular the distinction between smoking and not smoking, is more important than change process use in predicting cessation outcomes.
