In a study of the relationship between health habits and depression, 80 high school students, selected on an availability basis, were administered a Health Behaviors Questionnaire (HBQ) and the Beck Depression Inventory (BDI). The HBQ and the BDI significantly correlated (r=0.43p<0.01). Those who smoked were more frequently depressed than those who did not (X
2=10.5p<0.05), and those who used drugs other than marijuana were depressed more frequently than those who did not (X
2=9.2p<0.01). Mildly overweight boys (overweight by more than 5% of their ideal weight) and mildly under-weight boys (underweight by more than 5% of their ideal weight) were moreThis research was supported in part by a grant from the American Diabetes Association and by National institute of Health Grant MH 15529.Received his M.D. at George Washington School of Medicine.

The more pounds underweight the girls were, the more depressed they were (r=0.482, p<0.05). The closer the weight of a girl who perceived herself as overweight was to her ideal weight, the more depressed she was (r=–0.428,p<0.05). 相似文献

Self-esteem as measured by the Coopersmith Self-Esteem Inventory [Coopersmith, S. (1967),The Antecedents of Self-Esteem, Freeman, San Francisco] and ego development as measured by the Washington University Sentence Completion Test [Loevinger, J., and Wessler, R. (1970),Measuring Ego Development, Vol. I, Jossey-Bass, San Francisco] were evaluated in three groups of early adolescents: diabetic patients, nonpsychotic psychiatric patients, and a nonpatient group of high-school students. We found that low levels of ego development were associated with low levels of global and domain-specific self-esteem in all three subject groups. Levels of self-esteem among diabetic patients were not significantly different from those of nonpatients. While psychiatric patients had significantly lower self-esteem levels than the other groups, this difference was accounted for by preconformists, i.e., those at the lowest stages of ego development. Psychiatric patients reaching higher ego levels showed self-esteem levels indistinguishable from those of the diabetics and nonpatients.This study was supported by the youth development project of the Joslin DRTC (NIH AM20530-01), a grant from the Joslin Diabetes Center (NIH-BRSG), and NIH Grant AM27845.

Policy researchers have become increasingly familiar with a number of improved techniques for analyzing data obtained from interrupted time-series designs for evaluating public programs and policies. In this paper we contribute to this trend by presenting two groups of data analysis techniques which are not currently widely used by policy researchers, but are likely to be valuable adjuncts to traditional regression techniques for analyzing data obtained from interrupted time-series designs. First, aids for model specification are presented that enable the analyst to define an appropriate linear trend model—often one which will reduce the degree of multicollinearity and, therefore, produce more precise estimates of the impacts of a public program or policy. Next we consider approaches for point estimation and joint (simultaneous) interval estimation of a policy intervention's total effect at various points in time. 相似文献

Sex differences in verbal family interactions were investigated in a group of 79 adolescents and parents from normal and psychiatric settings. The analyses were designed to study these differences in both generations, parent and adolescent. Parent and adolescent interactions with one another were observed in a semistructured, revealed-differences family discussion. All of the individual speeches were then scored with our Constraining and Enabling Coding System (CECS). Initial predictions involved both adolescent and parent differences. These hypotheses were only partially confirmed. The strongest findings pertained to parent sex differences, as we found strikingly higher levels of cognitive enabling speeches expressed by fathers and significantly more speeches addressed to fathers. We discuss several alternative interpretations of these findings. Perspectives included in our considerations are direction of effect and influences of task/context upon the expression of family sex differences.This study was supported through a grant from the National Institute of Child and Human Development (NICHD Grant No. R01 HD18684-02) and a Research Scientist Development Award No. 5 K-02-MH-70178 (Dr. Hauser) from the NIMH.Received M.D. from Yale University and Ph.D. from Harvard University (psychology).

The end of apartheid in South Africa is typically characterised as ‘peaceful’. However, between 1985 and 1995, South Africa experienced a civil war in which more than 20,000 people died. In this war, the African National Congress (ANC) implemented a strategy of ‘people’s war’ based on Vietnam’s experience while the government pursued a counterinsurgency strategy based on models employed by the United States. In the war’s second phase, the ANC and Inkatha employed unconventional tactics in a campaign to gain political and military control of disputed territory. Owing to its success in the war, the ANC was able to prevent its rivals from significantly limiting its power in the central government after 1994 as well as exclude Inkatha from operating in key areas even in its home province. 相似文献
