The goal of this study was to examine the use of specific coping strategies among self-mutilating college students. The self-mutilating group (n = 44) reported utilizing avoidance strategies more often than did a control group (n = 44) matched for general psychological distress but with no history of self-mutilation. In addition, female, but not male, self-mutilators endorsed using problem-solving and social support seeking strategies less often than nonmutilators. These findings suggest that coping strategies in general and avoidance-based strategies in particular may be important targets for the treatment of self-mutilative behaviors.  相似文献

Personality psychology has a focus on understanding the functioning of the person as a whole, and is thus located at the hub of the other sub-disciplines of psychology and related sciences devoted to the study of human nature. As such, personality is well situated to integrate work emerging from different levels of analysis related to the distinctive organization and operation of psychological processes that characterize individuals. Personality psychology can have an exciting future to the extent that it can cross arbitrary lines of sub-disciplines, and connect with relevant interdisciplinary work devoted to understanding psychological phenomena, regardless of traditional boundaries. Several important areas of connection are highlighted, including links to social psychology, biology, and psychopathology, but trying to set priorities in terms of substantive areas for the field seems a futile exercise. Also discussed is the pressing need to find the most fruitful levels of abstraction at which to conceptualize our constructs to maximize their yield.  相似文献

Older adults are often stereotyped as dependent on others. This study explored how seeing an older adult receiving help triggers the dependency stereotype, by examining perceptions of older and younger adults helping and being helped by others. Participants (183 younger and older adults) read vignettes of young and old people helping others and rated the helpers and helpees on 2 variables: one a composite of dependency and capability; and the other composed of thoughtfulness, generosity, and unselfishness (i.e., considerateness). Participants rated older helpees as dependent, no matter who helped them. Younger helpers and those who helped the elderly rated high on considerateness. Females rated helpers more positively than did males. Implications of these findings for older adults are discussed.  相似文献

Two independent samples of pregnant smokers were interviewed about their cigarette smoking and were tested with biochemical markers at the beginning and end of their pregnancies. Participants were mainly unmarried, racial minorities (chiefly Hispanic), and residents of the inner city. Phi coefficients between self‐reported and chemical indicators ranged from .42 to .74. Contrary to expectations, the self‐report/biochemical‐measure correlations were higher at the end than at the beginning of the pregnancy term. The higher end‐of‐term correspondence between self‐report and chemical indicators likely reflected better reliability of the measures, when taken at term. The results are in accord with earlier research with other populations, indicating adequate validity for self‐reported smoking.  相似文献

Socially housed mice with cytotoxic lesions of the hippocampus do not exhibit social recognition memory 30 min following exposure to a juvenile mouse, however the social recognition memory of singly housed rats is unimpaired. The present study tests the hypothesis that social housing of rats could render social recognition memory hippocampally dependent as seen for mice. Rats were housed with juveniles or with adults. Two social recognition one-animal tests paralleling those used with mice were carried out. Seven social discrimination two-animal tests were also given. Sham operated and hippocampally lesioned rats had normal social memory at 30 min whether socially housed for 24, 48 h, 7 or 8 days prior to testing. These findings support other results indicating the hippocampus proper is not required for normal social memory in rats. In a final experiment, rats socially housed in groups of three since weaning, were tested for 30 min and 24 h social memory. Unlike mice, rats socially housed throughout life exhibited social memory only at 30 min, but not at 24 h. Manipulations that extend social memory in rats may be required to render social memory hippocampally dependent or rats and mice may differ in the neural mediation of social memory.  相似文献

Contingency management (CM) for drug abstinence has been applied to individuals independently even when delivered in groups. We developed a group CM intervention in which the behavior of a single, randomly selected, anonymous individual determined reinforcement delivery for the entire group. We also compared contingencies placed only on cocaine abstinence (CA) versus one of four behaviors (CA, treatment attendance, group CM attendance, and methadone compliance) selected randomly at each drawing. Two groups were formed with 22 cocaine-dependent community-based methadone patients and exposed to both CA and multiple behavior (MB) conditions in a reversal design counterbalanced across groups for exposure order. The group CM intervention proved feasible and safe. The MB condition improved group CM meeting attendance relative to the CA condition.  相似文献

This study examines whether availability of mental health resources in the county of residence is associated with subsequent suicidal behavior after a previous suicide attempt. Among 10,922 individuals who attempted suicide in Colorado between 1998 and 2002, residence in a county that offered a minimum safety-net of mental health services significantly reduced the risk of suicidal behavior for at least 1 year after the index attempt. Safety-net services included mental health treatment, crisis treatment, and case management. These results suggest one strategy for prevention of suicidal behavior that could inform state-level health policy development and resource allocation.  相似文献

Immigrants' sense of self can be derived both from being members of their ethnic in‐group and their country of residence. We examined how the ways in which immigrant adolescents integrate these self‐views in relation to academic success in German schools. Students describe themselves at school and when with family. Using a standardized literacy performance test, analyses revealed that immigrants whose school‐related self‐view did not include Germany were less successful: Students who described their self as including both aspects of their ethnic group and Germany, and students who saw themselves predominantly as German, outperformed students with purely ethnic school‐related selves. As expected, though, an ethnic family‐related self‐view did not have a negative impact on scholastic achievements.  相似文献
