Although organizational contexts have an influence on leadership, and some of their characteristics may facilitate (through weak structures) or inhibit (through strong structures) the leaders' behaviors, the extent of their influence has rarely been studied. Indeed, research of the influence of some types of contexts (entrepreneurial vs. non-entrepreneurial) on the emergence of certain variable...

This study quantitatively examined reasons for substance use among individuals with psychotic disorders and explored the relationship of these reasons to substance use problems and dependence. Sixty-nine people with psychotic disorders were interviewed using a battery of questionnaires called the Substance Use Scale for Psychosis (SUSP). Symptoms and medication side effects were also measured. ...

Prior research has shown that anxiety sensitivity (AS) is associated with smoking to reduce negative affect (e.g., [Comeau, N., Stewart, S.H., & Loba, P., (2001). The relations of trait anxiety, anxiety sensitivity and sensation seeking to adolescents' motivations for alcohol, cigarette, and marijuana use. Addictive Behaviors, 26, 803-825.]). However, given limitations in the measurement of smo...

INTRODUCTION A UK student survey examined the motivations for consuming energy drinks alone and mixed with alcohol, and aimed to determine whether the type of motive had a differential effect on overall alcohol consumption. METHODS The online survey (N = 1873) assessed alcohol consumption and motivations for consumption when mixed with energy drinks (AMED) and mixed with other non-alcoholic b...

Organizational citizenship behaviors (OCB) are workplace activities that exceed an employee's formal job requirements and contribute to the effective functioning of the organization. We explored the roles of the dispositional traits of individualism and collectivism in the prediction of OCB. The relationship was examined in the context of other constructs known to influence OCB, specifically, m...

Self-protection motives have been documented to influence a range of intergroup processes, including biased categorization of racially ambiguous targets as out-group members and a heightened ability to discriminate in-group from out-group members. In this work, the influence of self-protective states is extended to interpersonal processes. Specifically, in two experiments we demonstrate that ac...

This study aims to test the cross-cultural suitability of Modified Drinking Motives Questionnaire-Revised (M DMQ-R) (Grant, Stewart, O'Connor, Blackwell, & Conrod, 2007). The sample included 571 Spanish and 571 Canadian undergraduates between the ages of 18 and 22 (65.8% women). The confirmatory factor analysis demonstrated factorial invariance between samples. The regression analysis showe...

We conducted a study to investigate the motivational dynamics of protest participation. Previous research suggests that instrumental and identity motives together with group-based anger predict people’s intentions to participate in protest. The present research combines these motives with ideology into a single model. So far, no study has tested such a model or attempted to assess the motives’ ...

Goal-directed human behaviors are driven by motives. Motives are, however, purely mental constructs that are not directly observable. Here, we show that the brain's functional network architecture captures information that predicts different motives behind the same altruistic act with high accuracy. In contrast, mere activity in these regions contains no information about motives. Empathy-based...

As a complement to the literature on the discriminant validity of implicit and self-attributed motives, this study explored two issues that point to convergences: moderation of concordance between implicit and self-attributed achievement motives, and the role of the two types of motive as antecedents of achievement goals. Significant positive correlations were found between implicit and self-at...
