Vested interest theory (VIT), first investigated on environmental risk, suggests that the hedonic relevance of an attitude object moderates relations between attitudes, intentions, and responses to danger. Emphasizing vested interest may maximize impacts of risk communications. Study 1 (N = 215) assessed differences between inhabitants of two flood-risk areas in Italy on past experience, risk perceptions, concerns, attitudes, and behavioral intentions.Objectively, higher risk areas' residents reported more experience, and greater perceived risk and concern, while no preparedness differences were found (both at "between cities" and "within city" levels). Study 2 (N = 444) looked at the moderating role of VIT-based risk communication messages on the relationship between vested interest and behavioral intentions. Components of vested interest moderate attitude-intention consistency, suggesting a new method of developing effective risk announcements. Vested interest and attitude-behavior consistencyThat attitudes are functionally related to attitude-relevant behavior is an essential tenet of the field (Crano & Prislin, 2006;McGuire, 1985). A long history of research on attitudebehavior consistency has established the strong link between attitudes and consequent behavior (Crano & Prislin, 2006). This relation is widely recognized in social psychology, as is the possibility that other sources of variation (social, contextual, and intrapsychic) affect the strength of the relationship. Over the years, research has identified a number of factors that affect attitude strength and, consequently, attitudebehavior consistency (many variables implicated in attitude-behavior consistency is self-interest, which has been shown to moderate the attitude-action bond across a host of behaviors (Krosnick, bs_bs_banner

Depression is a mental illness affecting 121 million people. The Substance Abuse and Mental Health Services Administration recently launched a national, bilingual (English and Spanish) campaign to motivate young adults to support friends with mental illness. This article highlights and assesses the usefulness of two theoretically derived variables for increasing the social support received by all depressed individuals: (a) affect and (b) social support outcome expectations. In accord with the Substance Abuse and Mental Health Services Administration's bilingual campaign, the authors conducted two studies using intercepts at 2 swap meets in the U.S. Southwest. One study sample consisted of Spanish-dominant Hispanics, the other non-Hispanics. For both samples, results indicate that affect, social support outcome expectations, and their interaction accounted for more than 50% of the variance of social support intentions (67% in the Hispanic sample when familism was considered). Affect is commonplace in the helping behavior literature; results indicate social support outcome expectations deserve equal consideration. Moreover, an unexpected finding emerged: Perceiving a lack of willpower, need for attention, and lack of moral character to be the cause of depression resulted in increased sympathy among the Hispanic sample but increased anger among non-Hispanics.

This paper describes and contrasts three contemporary social psychological theories that focus on why people join and identify with groups: the sociometer model, terror management theory, and uncertainty–identity theory. The sociometer model argues that people have a need to be socially included, and that self‐esteem is a meter of successful inclusion and group belonging. Terror management theory argues that people are motivated to reduce fear of the inevitability of their own death, and that the consensual belief–confirmation provided by groups drives people to belong. Uncertainty–identity theory argues that people have a basic need to reduce uncertainty about themselves, their attributes, and their place in the world, and that cognitive processes associated with group identification reduce such uncertainty. We critically contrast these three accounts to conclude that all three motivational processes may play a role, but that self‐uncertainty may have the benefit of wide generality to all groups and group contexts and of detailed specification of cognitive processes.

This study assessed the moderating effects of attitudinal ambivalence on adolescent marijuana use in the context of the theory of planned behavior (TPB). With data from the National Survey of Parents and Youth (N=1,604), two hierarchical multiple regression models were developed to examine the association of ambivalent attitudes, intentions, and later marijuana use. The first model explored the moderating effect of ambivalence on intentions to use marijuana; the second tested the moderation of ambivalence on actual marijuana use 1 year later. Results across both analyses suggest that ambivalence moderated the association of friend norms and subsequent adolescent marijuana use: friend norms were better predictors of marijuana intentions (β=0.151, t=2.29, p=0.02) and subsequent use when adolescents were attitudinally ambivalent about marijuana use (β=0.071, t=2.76, p= 0.006). These results suggest that preventive programs that affect the certainty with which adolescents holds pro- or antimarijuana attitudes may influence the likelihood of their resistance to, initiation, or continuance of marijuana use.
