Mindfulness buffers the effects of cue-induced craving on alcohol demand in college drinkers

Alcohol consumption among young adult college students represents a significant public health problem. The presence of alcohol-related cues in drinkers’ environments can trigger powerful alcohol cravings, which may influence drinking outcomes. Less is known about how this cue-induced craving influences behavioral economic demand for alcohol. In addition, research has suggested that trait mindfulness may be an important buffer of the effects of internal states of craving on drinking decisions. Based on this literature, we hypothesized that cue-induced cravings would be associated with increased alcohol demand, an effect that would be attenuated among drinkers who have higher levels of mindfulness. Young adult college student drinkers (n = 69) completed a laboratory-based cue-induced craving assessment, a self-report assessment of trait mindfulness, and an alcohol purchase task. Findings revealed that cue-induced craving was related to higher alcohol demand. Consistent with the study hypothesis, acceptance, a component of mindfulness, buffered the effects of cue-induced craving on alcohol demand. Results raise the possibility that mindfulness-based interventions may be useful in helping disrupt the link between internal states of craving and drinking decisions in young adult college student drinkers

Development and validation of a breast cancer genetic counseling knowledge questionnaire

Women who undergo genetic counseling concerning their increased risk of developing breast cancer confront large quantities of complex information in a short period of time. Clinical reports have suggested that many women may not retain what they learned during counseling. A validated questionnaire to measure their knowledge, however, is lacking. In this study, we describe the development and validation of a questionnaire to assess knowledge of information typically included in genetic counseling for breast cancer. Items were empirically derived from detailed content analyses of actual genetic counseling sessions. The instrument’s content validity was high, as evidenced by high levels of independent interrater agreement (0.93) on items. Subsequent data reduction and confirmatory factor analytic techniques yielded a highly reliable (alpha = 0.92) 27-item Breast Cancer Genetic Counseling Knowledge Questionnaire (BGKQ). Direct comparison of this questionnaire to a scale previously developed in the literature (BCHK; [Breast Cancer Res. Treat. 53 (1999) 69]) supported the utility of the new questionnaire for evaluation of knowledge after counseling. Compared to non-counseled groups ( n=45), women who had undergone genetic counseling ( n=28) scored significantly higher ( P<0.0001) on the BGKQ, but not on the other questionnaire, establishing the BGKQ’s criterion validity. The BGKQ may, thus, provide a useful clinical and research tool for assessing knowledge of information provided during genetic counseling and exploring the potential impact of distress on knowledge, as well as the impact of knowledge on screening behaviors

Favorable associations with alcohol and impaired self-regulation: A behavioral economic analysis

Background: Recent research has demonstrated that both poor self-regulation and favorable implicit associations toward alcohol can play important roles in predicting drinking. Less well studied, however, is how the interplay between implicit associations and self-regulation may impact decisions about alcohol consumption. Behavioral economics is one important tool that may provide insight into the cognitive processes that impact demand for alcohol and drinking decisions. Methods: Healthy young adult participants completed an Implicit Association Task (IAT) that measured the strength of associations between approach/avoid attributes and target alcohol/neutral images. Impaired self-regulation was assessed by a classic delay discounting task. Participants also completed an Alcohol Purchase Task (APT), which yields multiple behavioral economic indices, chief among which are intensity (the number of drinks a participant would consume if the drinks were free) and elasticity (the degree to which an increased per-drink price impacts the number of drinks consumed in a hypothetical drinking situation). Finally, participants completed a timeline follow-back assessment of past-90-day drinking. Results: Findings indicated that implicit approach associations toward alcohol predicted increased demand for alcohol on the APT. Although delay discounting did not have a direct effect on demand for alcohol, there was a significant interaction between IAT and delay discounting, such that higher implicit alcohol approach associations predicted particularly high demand for alcohol among participants with poorer self-regulation. APT and IAT, in turn, predicted self-reported drinking behavior. Conclusions: These results suggest that favorable attitudes toward alcohol, together with poor self-regulation, can significantly impact drinking decisions in healthy young adults
