The relationship between academic performance and severity of depressed mood during medical school.

We employ a structural equation model to examine the relationship between academic performance and depressed mood over 4 years for a single medical school class. Academic performance measures included undergraduate gradepoint average, first- and second-year medical school gradepoint average, full Medical College Admissions Test (MCAT) and total National Boards Part I (NB) scores. Severity of depressed mood was assessed by administering the Beck Depression Inventory two times per year during the first 2 years, and once per year during the last 2 years. Overall there is little reason to think that depressive mood states compromise academic performance during the first 2 years of medical school for the class as a whole. Medical school grades had no direct impact on depressed mood, and mood had no direct impact on grades. There was a non-significant tendency for mood in the months preceding National Boards Part I to influence Board scores, which in turn influenced mood. Students with higher college gradepoint averages consistently reported fewer depressive symptoms throughout medical school. The latter result directs attention to a subgroup of medical students less susceptible to depression, or less prone to admit distress or symptoms. The non-susceptible and/or minimizing qualities of this subgroup merit further investigation.

Patterns of use of smokeless tobacco and the unidimensional model of drug involvement.

The present study tested whether smokeless tobacco (ST) fits a unidimensional model of drug involvement and tried to locate ST along the dimension that underlies drug use. The latent trait analysis was employed to quantify drug involvement in a sample of high school students. Analyses showed that although ST use fits the unidimensional model of drug involvement, the place of ST use along the continuum of drug involvement is not stable and differs by gender and ethnicity. Particularly for males, ST use is likely to be preceded by soft drug use and followed by hard drug use; for females, however, ST use is closely associated with hard drug use. The analyses also revealed that the fit of the unidimensional model and the location of ST use along the dimension vary with different ethnic groups.

A longitudinal comparison of the AIDS-related attitudes and knowledge of parents and their children.

As part of an evaluation of an experimental school-based AIDS risk-reduction program, data from 2,392 middle-school students in 15 high-risk school districts and from 1,627 of their parents were compared to examine how young adolescents and their parents differ with respect to AIDs-related knowledge and attitudes. At the time of the seventh-grade pretest, parents knew significantly more about AIDS than their children did. At the eighth-grade posttest, students who participated in the program knew either more than or at least as much as their parents in several subject areas, while among those not exposed to the program, parents still knew more than their children in most areas. The intervention had a positive impact on students' attitudes toward people with AIDS and on their degree of comfort about discussing with their parents such issues as drug use and sexuality.

The patterns and predictors of smokeless tobacco onset among urban public school teenagers.

This study describes the patterns and predictors of smokeless tobacco (ST) use in a large sample of urban public school students in Los Angeles and San Diego. The use of ST is more common among men than women and among Caucasians than African Americans, Hispanics, and others. Approximately 20% of the male respondents and 5% of the female respondents reported use of ST at least once, and 10.1% of male students and 3.1% of female students who had never tried ST by seventh grade started to use it by eighth grade. Among Caucasians, about 30% of boys reported trying ST at least once and 13.7% of those who had never used ST by seventh grade initiated experimentation by eighth grade. These data are used to examine the family, peer, and intrapersonal predictors of ST onset. The family risk factors for ST onset include living with a single parent, parent-child conflicts, and parental alcohol use. The peer risk factors for ST use include peer drug use and activities with friends, such as parties and participation in sports. The intrapersonal risk factors include poor grades in school, risk taking, and stress. The study also shows that those who use cigarettes, alcohol, or marijuana are at higher risk of using ST and vice versa. This study supports a problem-prone behavior perspective of ST use and cigarette smoking. We suggest that both products be targeted because the same programs are likely to apply to both products to counteract problem-prone type variables. Medical Subject Headings (MeSH): tobacco, smokeless chewing tobacco, adolescent behavior.
