Self-esteem, self-serving cognitions, and health risk behavior.

The current article reviews prospective and experimental research on the relation between self-esteem and perceptions of vulnerability. These studies demonstrate that individuals with high self-esteem who engage in risk behavior often utilize a variety of self-serving cognitive strategies that protect them from fully acknowledging their vulnerability to the potential negative consequences of their behavior; e.g., they minimize their estimates of personal risk and overestimate the prevalence of the risk behavior among their peers. The article also provides data on an additional self-serving cognitive strategy employed by adolescents with high self-esteem--alteration of perceptions of others' reactions to their own risk behavior. Finally, the article reviews the emerging literature on the relation between these cognitive strategies and maladaptive health behavior, and proposes that whether these strategies are maladaptive depends on the nature of the threat and the availability of opportunities to engage in compensatory self-enhancement.

The effect of peers' alcohol consumption on parental influence: a cognitive mediational model.

OBJECTIVE: The current study was designed to elucidate familial and social influences on adolescent alcohol consumption by testing three hypotheses derived from the prototype/willingness model of adolescent risk behavior: (1) parents' prototypes of adolescent drinkers affect adolescent consumption through their impact on adolescents' prototypes, (2) strong parent-child relationships are associated with acceptance of parental influence regarding drinking and thus with less adolescent drinking and (3) association with peers who drink dilutes parental influence over adolescents' alcohol consumption. METHOD: Two hundred sixty-six rural adolescents, ages 15 through 17 at Time 1, and their parents and siblings completed questionnaires about drinking behavior and drinking-related cognitions at 1-year intervals for 3 years. RESULTS: Structural equation models provided evidence of transmission of prototypes of adolescent drinkers from parents to adolescents and evidence that these prototypes mediate adolescent alcohol consumption. They also provide evidence that although parents' prototypes and parent-adolescent relationships are important in shaping the adolescents' drinking, association with peers who drink significantly attenuates this influence. CONCLUSIONS: These data suggest that parents can influence their children's drinking, but that this influence has more of an impact if the adolescent is not involved in a drinking-conducive peer environment. The current analyses also suggest that the process of becoming an adolescent drinker involves an active rejection of parents' influence rather than a passive movement away from parents' attitudes and beliefs-a process that is accelerated by association with peers who drink.

The effect of risk communication on risk perceptions: the significance of individual differences.

The purpose of this paper is to address the literature on the relation between risk communication and the initiation of health behavior change. More specifically, we examine the evidence that providing risk information is an effective way to change risk perceptions, as well as the more limited evidence that altering risk perceptions influences risk behavior. The paper discusses significant developments in the research on these issues, describes specific studies that represent trends in this research, and discusses methodologic issues important to the development of the field. Although there are relatively few studies that demonstrate causal links between risk communication and behavior change, recent developments in the field point to the importance of tailoring risk communications to the individual characteristics of targets. Such tailoring has taken a variety of forms, including providing individualized feedback concerning risk status or genetic vulnerability and assessing readiness for behavior change. Future intervention efforts should combine individualized risk status feedback with assessment of individual differences in previous behavior and acceptance of personal vulnerability.
