Psychometric evaluation of the short form inventory of drinking situations (IDS-42) in a community-recruited sample of substance-abusing women.

PURPOSE: We investigated the psychometric properties (factor structure, internal consistency reliability, concurrent validity) of the Short Form Inventory of Drinking Situations (IDS-42) in women substance abusers. METHODS: A sample of 297 substance-abusing women was recruited from the community. The women completed the IDS-42 and the three-factor Drinking Motives Questionnaire (DMQ). RESULTS: Confirmatory factor analyses of IDS-42 items suggested a hierarchical structure for the scale. Eight factors (corresponding to Marlatt and Gordon's eight heavy drinking situations) provided the best model fit at the lower-order level, and three factors (i.e., Negatively Reinforcing vs. Positively Reinforcing vs. Temptation Situations) provided the best model fit at the higher-order level. Lower- and higher-order IDS-42 subscales were shown to possess adequate-to-high levels of internal consistency. The eight lower-order IDS-42 factors demonstrated excellent concurrent validity with conceptually similar DMQ subscale scores. Across the entire sample of female substance abusers, a higher frequency of heavy drinking was reported in Positively Reinforcing Situations and Unpleasant Emotions Situations, as compared to other heavy drinking situations. IMPLICATIONS: Results support the IDS-42's good psychometric properties and demonstrate its utility as a tool in identifying situation-specific antecedents to heavy drinking among women substance abusers.

Effects of short-term food deprivation and chronic dietary restraint on the selective processing of appetitive-related cues.

OBJECTIVE: Selective processing of appetitive cues was investigated among food-deprived subjects and restrained eaters using the modified Stroop. METHOD: Thirty-two university students (25 females, 7 males) were randomly assigned to a 6-hr food deprivation (FD) or a no food deprivation (NFD) condition. Subjects were also divided into three restrained eating groups-high (HR), moderate (MR), and low (LR)-according to Restraint Scale scores. Subjects color named sets of food, alcohol, and leisure control words. Stroop color-naming latencies were submitted to 2 x 3 (Food Deprivation Condition x Word Type) and 3 x 3 (Restrained Eating Group x Word Type) repeated measures analyses of variance (ANOVAs). RESULTS: Food deprivation failed to produce longer latencies for food or alcohol words relative to control words. However, HR status was associated with significantly longer latencies for both food and alcohol, relative to control, words. DISCUSSION: Chronic dietary restraint but not short-term food deprivation was associated with selective processing of appetitive cues. The results have implications for understanding food preoccupation and risk for alcohol abuse in restrained eaters.

Examination of a three-dimensional drinking motives questionnaire in a young adult university student sample.

The literature on drinking motives suggests that individuals drink for three distinct reasons: coping motives (CM: to reduce and/or avoid negative emotional states); social motives (SM: to affiliate with others); and enhancement motives (EM: to facilitate positive emotions). Cooper, Russell, Skinner and Windle (1992) [Psychological Assessment, 4, 123-132] developed a 3-dimensional self-report instrument, the Drinking Motives Questionnaire (DMQ), with subscales designed to assess relative frequency of drinking for each of these three motives. This study was designed to examine the psychometric properties of the DMQ in a large sample of young adult university students. Three hundred and fourteen students voluntarily served as subjects; 266 students (85% of the total sample; 196F and 70M) reported drinking on the DMQ. These students were divided into two age groups [20 yr and under (n = 117); 21 yr and older (n = 149)]. Analyses of variance indicated: (a) main effects of gender, with men scoring significantly higher on the DMQ-EM subscale and tending to score higher on the DMQ-SM subscale when compared to women; (b) a main effect of age group on the DMQ-EM subscale, with younger students scoring significantly higher than older students; and (c) a significant main effect of drinking motive, with the most relatively frequent drinking reported for SM and the least for CM overall. Although mild-to-moderate shared variance between subscales was noted, the three subscales of the DMQ were found to possess adequate-to-high levels of internal consistency. A confirmatory factor analysis (CFA) showed that the hypothesized 3-factor model provided a better fit than either a unidimensional or 2-factor model in explaining the underlying structure of the DMQ. Some suggestions for improvements in DMQ item content are made. The present results replicate and extend previous findings by Cooper and colleagues to a sample of university students, and support the utility of using the DMQ in future investigations of the drinking motives of young adults.

Examination of the short form of the Inventory of Drinking Situations (IDS-42) in a young adult university student sample.

The 42-item version of the Inventory of Drinking Situations (IDS-42) assesses relative frequency of drinking behavior across eight categories of drinking situations and was originally developed as a method for identifying high-risk situations in alcoholic samples. This study was designed to examine the psychometric properties of the IDS-42 in a sample of university students in order to assess its suitability as an assessment tool in the non-clinical population. Three hundred and ninety-six students (111 M, 283 F, 2 with missing gender data) completed the IDS-42 and a well established measure of drinking motives, the Drinking Motives Questionnaire (DMQ). Confirmatory factor analysis of the IDS-42 established a hierarchical factor structure with eight lower-order factors and three higher-order factors of negatively-reinforcing situations, positively-reinforcing situations, and temptation situations. The eight lower-order IDS-42 factors demonstrated moderate to high internal consistency and excellent concurrent validity with conceptually-similar DMQ subscale scores. Non-parametric analyses revealed that male students reported a higher drinking frequency overall as compared to female students, particularly in IDS-42 situations involving Social Pressure to Drink, Pleasant Times with Others, Testing Personal Control, and Urges and Temptations. Across the entire sample of university student drinkers, a higher drinking frequency was reported in positively-reinforcing situations as compared to negatively-reinforcing situations and temptation situations, as predicted. Results suggest the IDS-42 possesses good psychometric properties and support its utility as a tool in identifying situation-specific antecedents to drinking among university students.

Anxiety sensitivity and situation-specific drinking.

To assess the typical drinking situations of high anxiety sensitive individuals, relative to low anxiety sensitive individuals, a large sample of university student drinkers (N = 396) completed the 42-item version of the Inventory of Drinking Situations (IDS-42) and the Anxiety Sensitivity Index (ASI). As hypothesized, ASI scores were significantly positively correlated with drinking frequency on the higher order IDS-42 factor of negatively reinforcing drinking situations and not significantly correlated with drinking frequency on the higher order factor of positively reinforcing drinking situations. Also, ASI scores were significantly positively correlated with drinking frequency on the lower order drinking situations factors of Conflict with Others, Unpleasant Emotions, and Physical Discomfort. ASI scores were also unexpectedly significantly correlated with more frequent drinking on the higher order factor of temptation drinking situations and with more frequent drinking on the lower order drinking situations factor of Testing Personal Control. These results have important implications for designing early prevention and intervention programs for high anxiety sensitive university student drinkers by helping them to develop alternatives to drinking in those situations (e.g., negatively reinforcing drinking situations) which place them at greatest risk for alcohol misuse.
