Cognitive Mediators (cognitive + mediator)
Selected AbstractsAlcohol Expectancies and Drinking Refusal Self-Efficacy Mediate the Association of Impulsivity With Alcohol MisuseALCOHOLISM, Issue 8 2010Matthew J. Gullo Background:, Recent work suggests that 2 biologically based traits convey risk for alcohol misuse: reward sensitivity/drive and (rash) impulsiveness. However, the cognitive mechanisms through which these traits convey risk are unclear. This study tested a model predicting that the risk conveyed by reward sensitivity is mediated by a learning bias for the reinforcing outcomes of alcohol consumption (i.e., positive alcohol expectancy). The model also proposed that the risk conveyed by rash impulsiveness (RI) is mediated by drinkers' perceived ability to resist alcohol (i.e., drinking refusal self-efficacy). Methods:, Study 1 tested the model in a sample of young adults (n = 342). Study 2 tested the model in a sample of treatment-seeking substance abusers (n = 121). All participants completed a battery of personality, cognitive, and alcohol use questionnaires and models were tested using structural equation modeling. Results:, In both studies, the hypothesized model was found to provide a good fit to the data, and a better fit than alternative models. In both young adults and treatment-seeking individuals, positive alcohol expectancy fully mediated the association between reward sensitivity and hazardous alcohol use. For treatment seekers, drinking refusal self-efficacy fully mediated the association between RI and hazardous drinking. However, there was partial mediation in the young adult sample. Furthermore, neither trait was directly associated with the other cognitive mediator. Conclusions:, The hypothesized model was confirmed on a large sample of young adults and replicated on a sample of treatment-seeking substance abusers. Taken together, these findings shed further light on the mechanisms through which an impulsive temperament may convey risk for alcohol misuse. [source] A preliminary examination of emotional and cognitive mediators in the relations between violence exposure and violent behaviors in youthJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 8 2008Maureen A. Allwood This study examined the possible mediational roles of posttraumatic stress disorder (PTSD) symptoms and acceptance of violence cognitions in the association between violence exposure and youth violent behaviors. This study also examined whether the strength of the relations between exposure and behavior varied across context of exposure and across sex. Participants were 123 early adolescents from the Midwest. Findings indicate a strong positive association between violence exposure at home and in the community. Regardless of context, violence exposure was significantly related to PTSD symptoms, acceptance of violence cognitions, and violent behaviors in youth. PTSD symptoms and acceptance of violence cognitions were both significant mediators in the exposure,behavior relationship but the associations differed for girls and boys and varied across context of exposure. © 2008 Wiley Periodicals, Inc. [source] The Hispanic Americans Baseline Alcohol Survey (HABLAS): Predictors of Alcohol Attitudes and Expectancies in Hispanic National GroupsALCOHOLISM, Issue 5 2010Britain A. Mills Background:, Multiple theoretical frameworks identify attitudes and expectancies as important predictors of alcohol behavior. Few studies have examined demographic predictors of these evaluative and belief-based cognitive mediators in the general population, and none have examined them in large-scale studies of Hispanics, a group at higher risk for drinking behavior and problems. This study probes the extent to which dimensions of attitudes and expectancies share common demographic predictors in a large sample of Puerto Ricans, Cuban-Americans, Mexican-Americans, and South/Central Americans. Methods:, The 2006 Hispanic Americans Baseline Alcohol Survey (HABLAS) used a multistage cluster sample design to interview 5,224 individuals randomly selected from households in Miami, New York, Philadelphia, Houston, and Los Angeles. This study focused on 2,773 respondents self-identified as current drinkers. Multiple linear regression was used to identify predictors of positive and negative dimensions of attitudes and expectancies, controlling for various background variables. Results:, Religious affiliation selectively predicted alcohol attitudes, with Catholics having more positive and fewer negative attitudes than other religious groups. Hispanic group selectively predicted alcohol expectancies, with Cuban-Americans having less positive and less negative expectancies than other groups. Being U.S.-born or male predicted more positive attitudes and expectancies, but birthplace and gender did not predict negative dimensions of attitudes or expectancies. Higher acculturation and more education were linked to a decreased tendency to agree with any item. Age was positively and negatively associated with negative expectancies and positive attitudes, respectively, and having never been married, higher income, and unemployment were each linked to fewer negative attitudes. Conclusions:, Although there is some overlap, attitudes and expectancies are influenced by different sociodemographic variables. Positive and negative dimensions of those constructs also show distinct patterns of relations. Prevention and treatment programs targeting cognitive mediators of behavior should be mindful of these differential determinants and future modeling endeavors should incorporate them. [source] WHAT DO PROACTIVE PEOPLE DO?PERSONNEL PSYCHOLOGY, Issue 4 2001A LONGITUDINAL MODEL LINKING PROACTIVE PERSONALITY AND CAREER SUCCESS We developed and tested a model linking proactive personality and career success through a set of four behavioral and cognitive mediators. A 2-year longitudinal design with data from a sample of 180 full-time employees and their supervisors was used. Results from structural equation modeling showed that proactive personality measured at Time 1 was positively related to innovation, political knowledge, and career initiative, but not voice; all measured at Time 2. Innovation, political knowledge, and career initiative in turn had positive relationships with career progression (salary growth and the number of promotions during the previous 2 years) and career satisfaction. Interestingly, voice had a negative relationship with career progression. We discuss practical implications and future research directions for proactive personality, extra-role behavior, and careers.
