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.

Coprophagia as a manifestation of obsessive-compulsive disorder: a case report.

Coprophagia is seen, though uncommonly, in psychiatric hospitals among adult patients with diffuse brain disease and in individuals with subaverage intelligence. We describe here a case of coprophagia in an adult with normal cognitive functioning. Thorough assessment revealed that this coprophagia was a manifestation of obsessive-compulsive disorder. The problem behavior responded to a behavioral treatment program comprising exposure and response prevention.

Thought suppression: an experimental investigation of spider phobics.

Researchers have observed that attempts to suppress a thought cause either an immediate increase in the occurrence of the thought (i.e. immediate enhancement effect) or a delayed increase in the occurrence of the thought (i.e. rebound effect). In this study, we examined whether suppression of a personally-relevant, emotional thought item (i.e. a spider to spider phobics) results in an immediate enhancement or a rebound effect. Forty-eight spider phobics were randomly assigned to either a suppression group or a control group. Subjects spent three 5-min periods alone monitoring their thoughts. During the first period, subjects in both groups were instructed to 'think about anything'. During the second period, subjects in the suppression group were instructed 'not to think of a spider', whereas subjects in the control group were instructed to 'think about anything'. During the third period, subjects in both groups were instructed to 'think about anything'. The number of spider-related thoughts was recorded for each period. Results from the second period failed to support an immediate enhancement effect. Evidence for a rebound effect, however, was obtained in the third period. The theoretical and clinical implications of these findings are discussed.

Food restriction and binge eating: a study of former prisoners of war.

Food restriction is correlated with binge eating, but evidence that restriction leads to binge eating is scanty. In this study we investigated postwar binge eating in 67 World War II combat veterans and 198 former prisoners of war. As predicted, binge eating was relatively rare in combat veterans but was significantly more prevalent in veterans who, as prisoners in German prisoner of war camps, lost significant amounts of weight during their captivity. Our data thus support the contention that starvation or dieting seems to precede binge eating.

Alexithymia and anxiety sensitivity in panic disorder and obsessive-compulsive disorder.

The authors compared scores on the Toronto Alexithymia Scale and the Anxiety Sensitivity Index of 27 patients with panic disorder and 31 patients with obsessive-compulsive disorder. Results suggest that patients with panic disorder constrict emotional experience, thereby reducing the likelihood of their experiencing physiological symptoms that accompany affect.

Alexithymia in victims of sexual assault: an effect of repeated traumatization?

The authors compared scores on the Toronto Alexithymia Scale of 12 rape victims with PTSD, 12 rape victims without PTSD, and 12 nontraumatized comparison subjects. Rape victims were more alexithymic than were nontraumatized comparison subjects, and subjects with a history of more than one episode of rape were more alexithymic than were subjects with a single episode.

Implicit and explicit memory bias for threat in post-traumatic stress disorder.

We investigated explicit (cued recall) and implicit (word completion) memory in Vietnam combat veterans with (n = 24) and without (n = 24) post-traumatic stress disorder (PTSD). Half of the subjects in each group encoded combat, social threat, positive, and neutral words elaboratively, whereas the others encoded these words nonelaboratively. On the cued recall test, under both encoding conditions, both groups recalled more combat words than other words. However, difference scores obtained by subtracting the mean recall for neutral words from the mean recall scores for the other words revealed that PTSD patients exhibited a relative explicit memory bias for combat words. That is, PTSD patients tended to exhibit poor memory for everything but combat words. On the word completion test, only PTSD subjects exhibited an implicit memory bias for combat words. This bias was greater for primed than for unprimed words, thereby ruling out a response bias. Such memory bias may underlie the 'reexperiencing' symptoms characteristic of PTSD (e.g. intrusive thoughts, nightmares).

Selective processing of threat cues in posttraumatic stress disorder.

Vietnam combat veterans with (n = 15) and without (n = 15) posttraumatic stress disorder (PTSD) performed a modified Stroop task in which they named the colors of neutral words (e.g., INPUT), positive words (e.g., LOVE), obsessive-compulsive disorder (OCD) words (e.g., GERMS), and PTSD words (e.g., BODYBAGS). In contrast to normal controls, PTSD patients took significantly longer to color-name PTSD words than to color-name neutral, OCD, and positive words. Because Stroop interference reflects involuntary semantic activation, it may provide a quantitative measure of intrusive cognitive activity--the hallmark symptom of PTSD.

The Levels of Emotional Awareness Scale: a cognitive-developmental measure of emotion.

The Levels of Emotional Awareness Scale (LEAS) is based on a new cognitive-developmental model of emotional experience. The scale poses evocative interpersonal situations and elicits descriptions of the emotional responses of self and others which are scored using specific structural criteria. Forty undergraduates (20 of each sex) were tested. Interrater reliability and intratest homogeneity of the LEAS were strong. The LEAS was significantly correlated with two measures of maturity: the Washington University Sentence Completion Test (SCT) of Ego Development, and the Parental Descriptions Scale-a cognitive-developmental measure of object representation. In addition, the LEAS correlated positively with openness to experience and emotional range but not with measures of specific emotions, repression or the number of words used in the LEAS responses. These findings suggest that it is the level of emotion, not the specific quality of emotion, that is tapped by the LEAS.

Interhemispheric transfer deficit and alexithymia.

The hypothesis that alexithymia reflects a functional disconnection between the two cerebral hemispheres was examined in 25 male combat veterans with posttraumatic stress disorder (PTSD). Multiple regression analysis revealed that the efficiency of interhemispheric communication, evaluated with a tactile finger localization task, was a significant predictor of the degree of alexithymia, as measured by the Toronto Alexithymia Scale, independent of PTSD severity and IQ. The PTSD subjects without alexithymia did not differ on the finger localization task from 10 male control subjects without alexithymia. These data suggest that at least some forms of alexithymia may be mediated by an interhemispheric communication deficit.

Differential effects of right unilateral and bilateral ECT on heart rate.

In a series of 11 melancholic patients who received both right unilateral and bilateral ECT during a single course of treatment, mean and minimum postictal heart rates were greater after bilateral ECT. Greater catecholamine release during bilateral ECT is the most likely explanation for these effects. These differences complement other evidence that bilateral ECT has a more pronounced physiological impact than unilateral ECT.
