Cannabis is one of the most commonly drugs used by teenagers. Expectancies about its effects play a crucial role in cannabis consumption. Various tools have been used to assess expectancies, mainly self-report questionnaires measuring explicit expectancies, but implicit measures based on experimental tasks have also been developed, measuring implicit expectancies. The aim of this study was to s...

We examine the moderating role of friendship and school network characteristics in relationships between 1) youths' friends smoking behavior and youths' own generalized expectancies regarding risk and future orientation and 2) generalized expectancies of youths' friends and youths' own generalized expectancies. We then relate these constructs to smoking. Using a longitudinal sample from the Nat...

The relationship between perceived loss of control and passivity in social activities in a non-handicapped institutionalized elderly population was assessed. Perceived loss of control was assessed from three different types of expectancies: low action-outcome expectancies, high situation-outcome expectancies, and low efficacy expectancies. Passivity scores were reported by the staff. The effect...

Negative alcohol expectancies have recently come to occupy a more important position in the expectancy literature, but recent claims that positive expectancies are unimportant in the consumption of alcohol when compared with negative expectancies are based on potentially flawed methodology. This study investigated the relative contribution of positive and negative expectancies to the consumptio...

BACKGROUND Simultaneous use of alcohol and cannabis predicts increased negative consequences for users beyond individual or even concurrent use of the two drugs. Given the widespread use of the drugs and common simultaneous consumption, problems unique to simultaneous use may bear important implications for many substance users. Cognitive expectancies offer a template for future drug use behavi...

• Examined how expectancies affect the relationship between mood and self-control. • Found association between positive mood and expectancies of mental restoration. • Found idiosyncratic expectancies mediate the effect of mood on perceived depletion. • Manipulated expectancies moderated mood’s conventional influence on self-control. • Expectancies of mental energy change are central in mood’s s...

Participants' expectancies and hypnotic performance throughout the course of a standardized, individually administered hypnotic protocol were analyzed with a structural equation model that integrated underlying ability, expectancy, and hypnotic response. The model examined expectancies and ability as simultaneous predictors of hypnotic responses as well as hypnotic responses as an influence on ...

The current study examined whether drinking and/or presence in the college social environment led to augmented positive alcohol expectancies among college students (N=225). Participants were approached during popular drinking nights as they exited events at which alcohol was consumed or in front of their residence as they returned home. Participants completed a brief questionnaire that included...

Children who expect they can bring about good outcomes and avoid bad outcomes tend to experience more personal successes. Little is known about factors that contribute to these ‘control expectancies’. The purpose of the present study was to determine whether children’s internal control expectancies occur in the context of parents’ internal control expectancies, low family strain, and high famil...
