Personality characteristics of restrained/binge eaters versus unrestrained/nonbinge eaters.

The present study used the Restraint Scale (Herman & Polivy, 1975) and the Binge Scale (Hawkins & Clement, 1980) to identify two distinct groups of college students: those who scored high on both scales ("restrained/binge eaters") and those who scored low on both scales ("unrestrained/nonbinge eaters"). Following subject identification, 26 restrained/binge females, 25 unrestrained/nonbinge females, 14 restrained/binge males, and 13 unrestrained/nonbinge males were administered the Beck Depression Inventory (BDI; Beck, Ward, Mendelson, Mock & Erbaugh, 1961), the California Psychological Inventory (CPI; Gough, 1975), and a questionnaire on bulimic symptoms (based on the Diagnostic and Statistical Manual of Mental Disorders, American Psychiatric Association, 1980) that allowed each subject to be classified as bulimic, binge eater, or normal eater. All of the students identified as bulimic were from the restrained/binge group and that group contained twice as many binge eaters as the unrestrained/nonbinge group. Students in the restrained/binge group were found to be more depressed than students in the unrestrained/nonbinge group and less well adjusted in areas of socialization, maturity, responsibility, and intrapersonal structuring of values. Results may be suggestive of personality factors tht predispose one to develop eating disturbances and/or useful in directing therapeutic intervention.

The assessment of bulimia in high school students.

This study attempted to: estimate the prevalence of bulimia among a sample of high school students; identify demographic variables associated with the disorder; and identify possible personality variables associated with bulimia. Based on the DSM-III criteria for bulimia, each of 257 students who participated in the study was assigned to one of three groups; 12 students (4.7%) were identified as bulimic, 88 (34.2%) as binge eaters, and 157 (61.1%) as normal eaters. Gender was the only demographic variable significantly associated with group, and all 12 of the bulimic students were female (7.1% of the female students). Personality differences were assessed with the California Psychological Inventory (CPI). On two of the scales, female students identified as bulimic and binge eaters scored significantly lower than students identified as normal eaters, indicating poorer adjustment. In males, none of the scales discriminated between the binge eater and normal eater groups. Results are discussed in the context of mental health needs among adolescents and high school students.

The assessment of bulimic symptoms and personality correlates in female college students.

A screening questionnaire for bulimic symptoms was completed by 244 college women. Approximately 79% reported binge eating (uncontrolled, excessive eating) occurrences. Twenty women (8.2% of the sample) reported self-induced vomiting after binge eating or "normal" meals. A subsample of 31 students were interviewed and administered the Restraint Scale, Compulsive Eating Scale, Beck Depression Inventory, Sixteen Personality Factor Questionnaire, and The Tennessee Self Concept Scale. Results showed a number of significant differences among students who binged only (" bingers "), self-induced vomiting (" purgers "), or did not binge or purge ("controls"). Bingers and purgers showed greater restrained eating tendencies and compulsive eating behaviors. On the 16PF, purgers scored lower on Factor Q3, which suggests lowered will control and less regard for social demands. Purgers also showed lower self-esteem, particularly in the areas of identity and family self-concept.

Cycloheximide produces adult-like retention deficits of prior learning in infant mice.

Utilizing a dosage of cycloheximide which was found to inhibit cerebral protein synthesis by almost 90% after injection, separate groups of 13-day-old mice received either cycloheximide or saline followed by 0 (control), 15, or 25 training trials in a discriminated shock-escape T-maze. Twenty-four hr later, each mouse was treated with cycloheximide or saline and tested for retention by an additional 25 trails in the T-maze. As reflected by correct choice-point turns, the results suggest that whereas salinetreated mice demonstrated reliable retention of prior learning, cycloheximide treated mice exhibited memory impairment; cycloheximide per se had no effect on performance during either original training or retest. A final experiment indicated that this memory impairment was not due to cycloheximide's general debilitating side effects at the time of retention testing. Taken together, these data suggest that protein synthesis inhibition during training impaired consolidation and/or retrieval processes involved in memory. The biochemical and behavioral effects following cycloheximide injection in 13-14-day-old mice in the present study parallel those reported with adult animals and lend indirect support to the hypothesis that the 24-hr memory capacity exhibited by these young mice reflects the early functioning of those processes involved in adult long-term memory.
