Development and validation of the Eating Behavior Inventory

The Eating Behavior Inventory (EBI) is a self-report instrument for assessing behaviors that have been theoretically implicated in weight loss, e.g., self-monitoring of food intake and of weight, refusing offers of food, eating at only one place, shopping from a list, eating in response to emotions. Thirty items were constructed in the form of first-person statements, e.g., I eat in the middle of the night. Each item was to be rated with a 5-point scale according to how often it was true for the respondent. Items were scored such that higher scores always reflected more appropriate (theoretically facilitative of weight control) eating patterns. Validity of individual items and total score was assessed in four studies. Twenty-six of the original items appeared valid and were retained. The resulting total score demonstrated validity in these studies and in two cross-validational comparisons. Internal consistency as measured by split-half reliability and correlations of item scores with total score was acceptable. One month test-retest reliability of item and total scores was satisfactory. Clinical and research applications of the EBI are discussed.An early version of this article was presented at the Taos International Conference on Treatment of Addictive Behaviors, Taos, New Mexico, February 1979.     

Selection for central excitation in Drosophila melanogaster

In two populations of Drosophila melanogaster, bidirectional selection and single-pair matings for high and low expression of central excitatory state (CES) succeeded in producing from one a high, but not a low, CES line, and from the other a low, but not a high, CES line. Compared with results from the selection studies of the blow fly, Phormia regina, in which one major gene correlate of CES has been found, the results from this study suggest that in D. melanogaster there are several gene correlates of CES, opposite alleles of some of which have become fixed in the divergent lines.     

Youth Functioning and Experiences in Inner-City After-School Programs Among Age, Gender, and Race Groups

Many dangers and challenges face inner-city minority children during their after-school hours. Youth development programs provide an alternative to spending this time unsupervised. We examined the relationship between children's experiences in selected urban Boys and Girls Clubs and child functioning. Because the sample (N = 296) consisted of African American and Hispanic boys and girls, aged 10–18, we were able to compare these relationships across race, gender, and age groups. There was no relationship between simple participation levels and child functioning, but significant linkages were identified between specific elements of the club experience and functioning. Relationships with club staff members and participation in club activities were associated with better functioning for older boys, a subgroup that is at considerable risk for delinquency. In addition, enjoyment of the club and not feeling badly treated there were associated with better functioning for all groups of children.
