Life cycle and loss--the spiritual vacuum of heroin addiction   总被引:1,自引:0,他引:1  
This research studied the function of heroin addiction as a family-learned method of coping with death, separation, and loss across the life cycle. Heroin addicts, psychiatric outpatients, and normal students were given an extensive interview and test battery to determine the incidence of loss of family members and significant others. Because the impact of death is often overcome through religious rituals, this study also investigated the subjects' perception of their families' religious values and orientation to life's meaning and purpose. Results indicate that the incidence of death differs significantly across groups and that addicts have a distinct orientation to death, are more suicidal, and have more premature and bizarre death experiences. During childhood they have more family separations, and they tend to develop a distinct pattern of continuously separating from and returning to their families. They are also less likely to have a clearly defined purpose in life. A subset of parents from each group were also interviewed and tested, and these results support the theory of the intergenerational transmission of behavior.  相似文献

Whether the empty-nest experience has positive or negative consequences for women's well-being at midlife may depend on their historical cohort membership and employment status. In this study, it was posited that the empty nest was likely to be a negative experience among the particular cohort of women (Cohort II) who reached adulthood during the period of strong societal emphasis on women's maternal role known as the feminine mystique, would be experienced positively among the earlier cohort (Cohort I) who as young adults were encouraged to enter the labor force during World War II. Analyses of covariance tested the relationships among empty-nest status, cohort membership, and employment status, and three measures of psychological well-being, adjusted for age, education, and marital status. The results of this study show that cohort and employment each have important independent associations with women's well-being at midlife, but that the experience of the empty nest depends on these two factors, especially cohort experiences.The authors wish to thank Joseph Veroff, Elizabeth Douvan, and Richard Kulka for the use of the data from The Study of Modern Living, and Joseph Veroff for comments on an earlier version of this paper.  相似文献

Individuals in intimate relationships engage in higher levels of HIV risk behavior than do individuals engaging in casual sex (e.g., Bowen & Michal-Johnson, 1989; Misovich, Fisher, & Fisher, 1996). While there are many possible reasons for this consistent pattern of effects, few studies have focused on identifying the underlying causes. Therefore, same-gender focus groups were conducted with college-age men and women in intimate relationships as participants in order to examine, qualitatively, factors particular to relationships which are associated with HIV risk. Focus-group members indicated that concerns about questioning interpersonal trust and commitment in their relationship through the introduction of condoms or HIV testing were often strong impediments to these practices. Recommendations for future HIV-prevention interventions specific to individuals in relationships are discussed.  相似文献

The relationship between depression and somatic symptoms such as headache has never been explained. Both depression and headache appear to become more prevalent among women than among men only for cohorts that reach adolescence during periods of great change in opportunities for a female's academic achievement. In Studies 1a and 1b, the same pattern was found to apply to the correlation between depression and headache. In Studies 2a and 2b, self-report measures of depression and headache were found to share significant variance only among female adolescents who reported concerns regarding the limited achievements of their mothers. These females may view the roles of adult women as being limited and may experience stress and low self-esteem associated with depressive and somatic symptomatology.  相似文献

Knowledge of basic arithmetic facts aids in the acquisition and speed of performance of arithmetic operations. A peer mediated instructional procedure, Classwide Peer Tutoring (CWPT), has been shown to increase the rates and accuracy of students responses to academic tasks and to improve student performance on a variety of academic tasks. The present investigation evaluated the retention of 100 subtraction items by primary grade-age children with mild disabilities using CWPT for 10 weeks. Short- and long-term retention of items, and rate of correct responding were assessed. Results indicated that the students' average pretest score was 58.0% correct, and their average weekly posttest score was 87.12 correct, a 27% improvement in accuracy. Short- and longer-term retention measured on posttests was 88.7 % and 85.0% correct, respectively. Improvement in students rate of accurate responding to subtraction items practiced during CWPT was obtained. Student failure to learn particular items was not attributable to fewer opportunities to practice these items, less accurate practice, or item difficulty. Students reported positive evaluation of CWPT and perceived positive social and self esteem outcomes. Directions for future research focusing on retention and analysis of treatment failure are suggested.  相似文献

The implications of exposure to acute and chronic stressors, and seeking mental health care, for increased psychological distress are examined. Research on economic stress, psychological distress, and rural agrarian values each point to increasing variability within rural areas. Using data from a panel study of 1,487 adults, a model predicting changes in depressive symptoms was specified and tested. Results show effects by size of place for men but not for women. Men living in rural villages of under 2,500 or in small towns of 2,500 to 9,999 people had significantly greater increases in depressive symptoms than men living in the country or in larger towns or cities. Size of place was also related to level of stigma toward mental health care. Persons living in the most rural environments were more likely to hold stigmatized attitudes toward mental health care and these views were strongly predictive of willingness to seek care. The combination of increased risk and less willingness to seek assistance places men living in small towns and villages in particular jeopardy for continuing problems involving depressed mood.  相似文献

The Structure of Personal Commitments   总被引:2,自引:0,他引:2  
ABSTRACT This article examines the structure of personal commitments across several dimensions ot commitment experience and across multiple samples In Sample 1, one hundred ninety-seven subjects rated 41 commitment items along the dimensions of importance, expectancy to achieve, effort, and distress, in Sample 2, two hundred five subjects rated the same items along the dimensions of importance, current commitment, and visibility Principal components analyses produced six component solutions within each of the rating dimensions Using a multitrait-multimethod format, comparisons of the component solutions suggested that the six components ( a ) represented independent groupings within each solution and ( b ) remained consistent across the different dimensions of commitment experience The six components of commitment were identified as Affiliation, Power/Achievement, Personal Growth, Altruism, Stress Avoidance, and Sensation-Seeking  相似文献
