A total of 499 patients hospitalized for suicide attempts (attempters) between 1970 and 1975 were followed until 1982; of this group, 28 (5.6%) eventually committed suicide. Six (14.6%) of the 41 patients who had been interrupted during their initial attempts eventually committed suicide, whereas only 22 (4.8%) of the 458 patients who had not been interrupted eventually committed suicide. The interrupted attempters were approximately three times more likely to commit suicide than the uninterrupted attempters. 相似文献

The purpose of this paper is to determine the nature of the drug‐crime relationship by exploring the influence of friend behaviors on both adolescent delinquent and substance using behavior. The sample consists of 1381 adolescents evenly divided by gender into three age groups (12, 15 and 18 years old). In general, there is an increase in intensity of substance use from the youngest to the oldest age level with male and female levels being similar within each age group. There are both age and gender differences when examining delinquent behavior. There is a relationship between adolescent drug use and crime (especially among males), however this relationship is relatively modest. In addition, while friends’ behavior is a very strong predictor of the same type of behavior in subjects, there are no strong crossover relationships. Thus, the hypothesis that both types of behavior are part of a specific deviant peer subculture is not confirmed. 相似文献

This study extends previous research addressing sex differences in perceived occupational barriers and evaluates the mediating role of causal attributions in the relationship between perceived occupational barriers and career maturity. Participants (85 women and 30 men) listed their perceived barriers to occupational goals, completed a measure of attributions for career decision making, and completed 2 different measures of career maturity. Findings revealed that a larger proportion of women than men perceived past barriers associated with family-related issues. Results also revealed a significant, negative relationship between the number of perceived occupational barriers and career maturity for participants who believe that career decision making is an externally caused, uncontrollable process. The implications of these findings and suggestions for career counselors to integrate perceived barriers into the counseling process are discussed. 相似文献
