Temptation, restriction, and the regulation of alcohol intake: validity and utility of the temptation and restraint inventory.

OBJECTIVE: The Temptation and Restraint Inventory (TRI) is a measure of drinking restraint, the preoccupation with controlling alcohol intake. It contains two higher order factors pertaining to the temptation to drink and the restriction of alcohol intake. We tested the convergent and discriminant validity of the TRI in comparison to the Preoccupation with Alcohol Scale (PAS), the Reasons for Limiting Drinking Scale (RLD) and the Drinking-Related Locus of Control Scale (DRIE), each of which measures constructs analogous to the components of the TRI. We also tested the utility of the TRI, as compared to these related measures, for predicting typical drinking and alcohol problems. METHOD: A sample of 296 (50% male) moderate to heavy drinking adults completed the TRI, the PAS, the RLD, the DRIE and measures of typical (weekly) drinking and alcohol problems (SMAST). RESULTS: Correlations indicated that the TRI had excellent convergent and discriminant validity. The TRI's temptation factor (Cognitive and Emotional Preoccupation) was strongly and positively correlated with the PAS and the DRIE, and was weakly and positively correlated with the RLD. The TRI's restriction factor (Cognitive and Behavioral Control) was positively and moderately correlated with the DRIE and moderately to weakly correlated with the PAS and the RLD. In regressions predicting weekly drinking and SMAST scores, the TRI was particularly effective in accounting for the variance in SMAST scores. CONCLUSIONS: In comparison to measures of conceptually related constructs, the components of the TRI showed excellent convergent and discriminant validity. The TRI accounted for large portions of the variance in alcohol-related outcomes, using fewer items than measures of similar constructs.

A longitudinal assessment of teacher perceptions of parent involvement in children's education and school performance.

This study examines the ways in which parental involvement in children's education changes over time and how it relates to children's social and academic functioning in school. Teachers provided information on parent involvement and school performance for 1,205 urban, kindergarten through third-grade children for 3 consecutive years. They rated the following four dimensions of parent involvement: frequency of parent-teacher contact, quality of the parent-teacher interactions, participation in educational activities at home, and participation in school activities. As predicted, the frequency of parent-teacher contacts, quality of parent-teacher interactions, and parent participation at school declined from Years 1 to 3. Every parent involvement variable correlated moderately with school performance and parent involvement in Years 1 and 2, and accounted for a small, but significant amount of variance in Year 3 performance after controlling for initial performance level. Participation in educational activities at home predicted the widest range of performance variables. Results suggest that enhancing parental involvement in children's schooling relates to improvements in school functioning.

Drinking restraint and alcohol-related outcomes: exploring the contributions of beverage instructions, beverage content and self-monitoring.

OBJECTIVE: We examined the role of drinking restraint (temptation and restriction), beverage instructions and content and self- monitoring in alcohol-related outcomes (consumption, subjective intoxication and blood alcohol concentration [BAC]) in a sample of moderate-to heavy-drinking young men. METHOD: Male social drinkers (N = 132) participated in an individualized taste-rating task (TRT), an unobtrusive method for determining ad libitum alcohol consumption. Beverages were presented using the format of the balanced placebo design (BPD), in which subjects' expectation of an alcoholic versus a non- alcoholic beer was crossed with their receipt of an alcoholic versus a nonalcoholic beer. During a single 30-minute drinking occasion, each subject sampled two beers and rated their taste characteristics on a computer. RESULTS: Consumption during the TRT, ratings of subjective intoxication and postdrinking BAC, served as criterion variables in regressions in which BPD beverage condition, the two aspects of drinking restraint, self-monitoring, and their interactions, served as the predictors. The results indicated that TRT consumption was mainly a function of the temptation to drink (an aspect of restraint). As expected, assignment to the conditions of the BPD predicted subjective intoxication and BAC. Self-monitoring did not have an impact on any of the alcohol- related outcomes. CONCLUSIONS: The results for TRT consumption suggest that drinking restraint, particularly the temptation to drink (i.e., view the regulation of intake as difficult and/or drink to repair negative affective states), enhances the consumption of social drinkers during a single drinking occasion. Consistent with previous research, the conditions of the BPD predicted some alcohol-related outcomes.

Affective and behavioral reactions to the violation of limits on alcohol consumption.

The limit violation effect (LVE) was studied by inducing male social drinkers to consume either more or less beer than their prestated limit on alcohol intake. Affective and behavioral reactions to the violation of drinking limits were mediated by attributional style and aspects of drinking restraint. Subjects who reported greater than average levels of self-blaming attributions, restrictions on alcohol intake and cognitive preoccupation with alcohol became depressed and angry after the violation of drinking limits. In contrast to the hypothesized excessive-drinking component of the LVE, subjects who experienced negative affective reactions to the violation ordered fewer shots in a subsequent whiskey-tasting task. Possible conceptual and methodological reasons for observing only the affective component of the LVE are discussed.

On the enhancement of creativity by alcohol: pharmacology or expectation?

Creative individuals may use psychoactive drugs to enhance their ability to produce creative works, but it is difficult to differentiate the pharmacological effects from other influences. Part of the problem is that creativity defies any simple definition, making it hard to determine when or how much creativity is evident. The other major obstacle is that life circumstances are confounded with the propensity to use drugs (including alcohol), so the causal relation of drugs to creativity is uncertain. We examined this question by an experiment in which subjects were asked to creatively combine pictures of wildflowers that were implicitly organized around a set of three dimensions: color, shape, and number. Pharmacological and expected effects of alcohol were dissociated in the experiment by using the balanced placebo design (BPD). The results showed no pharmacological effect of alcohol on the creative combinations that subjects produced. However, the novelty and structural recombination of the wildflower arrangements were enhanced when subjects thought they had consumed alcohol, whether or not they had actually done so. Implications for measuring creativity and the possible motivation to use drugs for creative effect are discussed.

Psychopharmacological effects of alcohol on time perception: the extended balanced placebo design.

Time perception is affected by the pharmacological action of many drugs, but the contribution of expected effects of drugs has not been considered. A new design, the extended balanced placebo design (EBPD), is presented to study both the pharmacological and expected effects of alcohol on time perception. The EBPD makes it possible to examine the effects of alcohol across a broad range of expected and pharmacological doses. By contrast, the domain of inquiry was limited to low doses of alcohol in the original balanced placebo design. The design was later modified to study higher doses, but the control and the pure drug and expectancy conditions were sacrificed in the transformation. In the EBPD, however, any realistic combination of the expected and actual dose of alcohol can be studied, while retaining pure drug and expectancy conditions. The EBPD was tested in the present study with respect to its psychopharmacological effectiveness and the effects of alcohol on time perception. The design was effective in terms of three manipulation checks: blood alcohol concentration, subjective intoxication and postexperimental beliefs about the alcohol content of the beverage consumed. In addition, the expected and actual doses of alcohol interacted over time to evidence active compensation for the pharmacological effects of alcohol on time perception. Finally, a covariance structure model was confirmed in which the expected and actual doses of alcohol increased the perceived rate of time passage, which in turn lengthened objective estimation of a one-second interval.
