Health values buffer social-environmental risks for adolescent alcohol misuse.

Data from a representative sample of 17- to 20-year-old adolescents were analyzed to investigate whether a health-valuing attitude could buffer the effects of social-environmental risk on adolescent alcohol misuse. A risk index was constructed for adolescents, based on variables such as friends' drinking, parental alcohol abuse, and poor parental monitoring and communication. The expected buffering interaction called for high environmental risk to lead to greater alcohol misuse for adolescents who placed low value on health, but not for those who placed high value on health. The expected interactions were obtained for 2 alcohol-related variables (total consumption and consuming 5 or more drinks at a time).

Social and coping reasons for drinking: predicting alcohol misuse in adolescents.

OBJECTIVE: Motivational models of alcohol consumption suggest a positive relationship between reasons for drinking and the amount of alcohol consumed. The present study examined race, gender, and age as moderators of the relationship between social and coping motives and alcohol misuse in black and white adolescents. METHOD: A representative population sample (N = 699) of male and female (54%) adolescents between the ages of 13 and 16 was recruited using a random-digit-dial telephone procedure. Six face-to-face interviews with subjects and their families were carried out at approximately yearly intervals. Information gathered assessed alcohol use, social and coping motives for drinking, and psychological distress. RESULTS: Multiple analyses, including both cross-sectional and longitudinal logistic regression analyses and survival analysis were used to examine the relationship of drinking motives to adolescent alcohol misuse. Contrary to our predictions, social motive was a somewhat better predictor of alcohol misuse than was coping motive, particularly during mid- to late adolescence. However, there was some limited evidence of a significant relationship between coping motives and alcohol misuse in the mid-adolescent age group. Some support was found for racial differences such that social motives are better predictors of alcohol misuse among whites than among blacks and coping motives are better predictors among blacks. Few gender differences were found in the relationship of drinking motives and alcohol misuse. CONCLUSIONS: These findings suggest a stronger tendency for social and coping motives to influence alcohol misuse during mid to late than in early adolescence. Research examining the development of motives and the mechanisms by which they influence drinking behavior is needed.

Parental and peer influences on the onset of heavier drinking among adolescents.

OBJECTIVE: Less is known about heavier drinking in adolescents than about alcohol initiation. The present study examined the emergence of regular (weekly) and heavy episodic (five or more drinks at a time) adolescent drinking as a function of social influence (modeling and social control) from parents and peers. METHOD: A three-wave study was conducted using a representative household sample of families in metropolitan Buffalo, New York (N = 612). Over half (54%) of the adolescent respondents were female. Black families made up 30% of the sample. Interviews were conducted at 1-year intervals. Adolescent drinking was dichotomized at each wave into abstinence/light drinking versus regular drinking. Logistic regression including only adolescents who were abstainers/light drinkers at Wave 1 was performed to assess which Wave- variables could predict regular-drinking onset by Wave 2; a similar analysis examined the onset of heavy episodic drinking by Wave 2. Parallel analyses using Wave-2 variables to predict the onset of the drinking outcomes by Wave 3 were also conducted. RESULTS: Across the different analyses, the strongest psychosocial predictors of advancement to heavier drinking were friend's drinking and low parental monitoring. Also, white adolescents were at greater risk than their black counterparts. CONCLUSIONS: A multidimensional approach to prevention that addresses different processes of influence (e.g., modeling and social control) involving both parental and peer domains is likely to be most successful in deterring the onset of heavier drinking in adolescents.

Effects of Brazelton demonstrations on later parenting: a meta-analysis.

Meta-analysis of parenting interventions based on the Neonatal Behavioral Assessment Scale (NBAS) was conducted. Only published studies (n = 13) were included in this analysis, with one effect size entered for each study. The studies contained a total of 668 families, an average of about 51 per study. Effect sizes are reported in terms of the correlation coefficient (r) as well as the difference between experimental and control group means divided by the pooled standard deviation (Cohen's d). Analyses were conducted by weighting each study equally (unit weighting) and also by sample size. Similar average effect size were obtained for both weighting procedures (r's of about.2, d's of about.4), indicating that Brazelton-based interventions during the neonatal period have a small-moderate beneficial effect on the quality of later parenting. The probability of obtaining these findings by chance approached zero. The potential factors influencing these results are discussed, as well as directions for future research.

Vietnam combat exposure and recent drug use: a national study.

Traumatic life experiences may have long-term adverse psychological consequences, including illicit drug use. We analyzed data from the 1985-1986 Centers for Disease Control Vietnam Experience Study to investigate this issue. Over 2,400 Vietnam veterans indicated the amount of combat to which they had been exposed, and reported on their drug use while in the Army and during the year interval prior to the interview. Combat exposure was significantly related to recent drug use, even when Army drug use and demographic factors were controlled statistically.

Individual differences in perceived riskiness of drinking in pregnancy: antecedents and consequences.

OBJECTIVE: This study examined whether differences in perceived riskiness of alcohol consumption during pregnancy were related to self-reported alcohol consumption among a community sample of pregnant women. Further, this study examined the impact of prior experiences on risk perceptions, focusing on previous pregnancy experiences and on previous alcohol-related problems. METHOD: The hypothesized relationships among variables were tested simultaneously in a structural equation model. Subjects included 159 pregnant women, all of whom drank regularly before pregnancy recognition, who were recruited from prenatal clinics and through newspaper advertisements. RESULTS: Perceived riskiness of drinking during pregnancy was lower among women who had previously given birth to a healthy child and among women with greater numbers of previous alcohol problems. Prior adverse pregnancy experience did not predict perceived risk. Perceived risk negatively predicted actual alcohol consumption during pregnancy, suggesting that previous healthy pregnancy experiences and alcohol problems increase drinking in pregnancy indirectly, through perceived risk. A direct positive effect from previous alcohol problems to drinking in pregnancy also was observed. CONCLUSIONS: Findings suggest that risk perceptions play a role in drinking behavior among pregnant women and help to illuminate the relationship between parity and alcohol consumption. Interventions designed to reduce drinking among pregnant women, which have generally relied on providing information, may be improved by considering the impact of previous experiences and addressing erroneous beliefs.

Adolescent suicidal behaviors as a function of depression, hopelessness, alcohol use, and social support: a longitudinal investigation.

Surveyed two high school cohorts (ns = 698 and 283) to study independent, prospective predictors of adolescent suicidal behaviors (thoughts, communication to others, attempts). Within each cohort, there were two measurements conducted 6 months apart. Structural equation models were tested, with depressive symptoms, hopelessness, alcohol consumption, social support, and gender serving as predictors. In the larger cohort, depression predicted later levels of all three suicidal behaviors controlling for baseline suicidal behaviors. Also, suicidal thoughts predicted later communications, and suicide attempts predicted future thoughts. In the smaller cohort, alcohol consumption predicted all three suicidal behaviors at the later measurement, whereas depression was predictive only of later thoughts. Major issues regarding prevention, theories of suicide and negative affect, and methodological/analytical approaches were discussed.

Social relationships, recovery from illness, and survival: a literature review.

Do medical patients with a high quantity or quality of social relationships have greater chances of recovery and survival than more isolated individuals? This article reviews longitudinal studies of social relationships and recovery published since the last major reviews of this field. Reports of 26 such projects were located, primarily in the areas of heart disease (13 studies) and breast cancer (7 studies). Being married (or socially supported in other ways) was generally associated with survival or freedom from recurrence in multiyear follow-up studies of myocardial infarction (MI) and coronary artery disease patients, although social support produced negative or mixed results in studies of short-term physical adaptation after Ml or bypass surgery. Studies relating marital status and other support variables to recurrence and survival in breast cancer patients also had mixed results. The small number of studies, and other limitations associated with them, suggest caution in drawing strong conclusions.

Stress, structural social support, and well-being in university students.

This paper reports an investigation of the relationship between college students' social support and social interaction and their health and well-being. The authors analyzed data from a telephone survey of 161 students at a large state university to test for stress-buffering and main effects on well-being of four types of structural social support. Frequency of participating in activities with other students was negatively associated with depression symptoms and positively associated with feelings of health and physical fitness. The other support measures (number of friends on campus and whether respondents belonged to groups on campus or had a romantic relationship) yielded less consistent main effects and Stress x Support interactions that were inconsistent with a buffering model. Interpretations that focus on the role of affectively positive social activities in the well-being of college students are discussed.

Self-monitoring and age.

Two adult samples were surveyed to investigate the relation between individuals' levels of self-monitoring and age. A negative relation was predicted as older individuals were seen as most likely to exhibit the low self-monitoring tendency of behaving in accordance with one's own attitudes and feelings, whereas younger individuals appeared most likely to exhibit the high self-monitoring tendency of behaving according to social cues. A significant negative correlation between age and self-monitoring was found in both samples. The self-monitoring construct is discussed in relation to other social-cognitive life-span differences and to the idea of critical periods throughout the life span.

DNA methylation pattern is determined by the intracellular level of the methylase.

Extrachromosomal plasmid DNA is transiently undermethylated in Escherichia coli during amplification in the presence of chloramphenicol. In addition, undermethylation of phage lambda DNA was observed after thermal induction of a lambda c1857 lysogen while the integrated lambda phage DNA was found to be fully methylated. These methylation pattern changes occur under conditions (extensive replication) in which the intracellular methylase level becomes limiting. In an E. coli strain that harbors a plasmid that carries the dam methylase gene and therefore overproduces dam methylase, there is no undermethylation of dam sites in either of the extrachromosomal DNAs. The sites that are methylated by the mec methylase in both plasmid and lambda phage DNAs were undermethylated in the dam overproducer as well. These results indicate that the intracellular level of the E. coli methylase determines the DNA methylation pattern.

Lithium: a brake in the rising cost of mental illness.

Lithium has been extraordinarily successful in the treatment of manic-depression. To compute the economic impact of that success on the United States, an estimate of the cost of care for manic-depression before lithium was introduced was compared with cost estimates after lithium. Economic gains in production were also calculated. Assumptions and exclusions err on the conservative side so that estimates, if inaccurate, are low. The use of lithium as a treatment for manic-depression has saved +2.88 billion in ten years and resulted in a +1.28 billion gain in production, or a conservative total of over +4 billion.
