One hundred ninety-four hospitalized adolescents were administered the Adolescent Depressive Experiences Questionnaire (DEQ-A). The DEQ-A factors (dependency, self-criticism) correlated well with independent measures of depression, hopelessness, self-esteem, and suicide risk. After controlling for depression, self-criticism and dependency showed differential associations with hopelessness, violence potential, and impulsivity. A subgroup of 84 inpatients identified as either highly self-critical or highly dependent based on the DEQ-A was also compared for differences in personality and symptomatic behavior. Self-critical and dependent patients exhibited equally high levels of depression, hopelessness, suicidality, and low self-esteem. Few differences were observed in personality or symptomatic behavior between the two groups. These findings, while extending previous research that relied on community samples of young adults, provide only mixed support for a distinction between these two categories of depression.  相似文献

Most research on self-handicapping has focused on adults. Only a few studies have examined self-handicapping in adolescents or the particular characteristics of the family environment that are associated with self-handicapping. Adolescents (N = 141) and their mothers completed a series of questionnaires assessing adolescent self-handicapping, adolescent dysphoria, and parenting variables in mothers, including parenting styles (care and overprotection) and parenting stress due to situational variables, parent–child dysfunctional interactions, and behavioral characteristics of the child. Results showed (a) that self-handicapping was positively related to age in girls, but not in boys, (b) that there was a strong relation between self-handicapping and dysphoria in both boys and girls, (c) that mother-rated care negatively predicted self-handicapping in girls beyond the effects due to girls' dysphoria, and (d) that maternal care moderated the relationship between self-handicapping and dysphoria in boys. Maternal care and depressive affect in young persons are independently related to self-handicapping behaviors in adolescents. Results are discussed in terms of implications for the hypothesized etiology of self-handicapping.  相似文献

This paper examined the development role of community banks in rural Nigeria by using the deposit mobilization capability and funding capacity in key sectors of the rural economy as yardsticks. By using a cluster sampling technique, it looks at the achievements of the community banking scheme initiative in terms of economic development. The scheme, established in 1991, has sustained itself and promoted rural development in the country. It is noted that communities have, for the first time, realized that they can advance their own economic fortunes. However, the scheme's performance as supporter of the agricultural sector has not been as well as expected, despite the fact that agriculture dominates Nigeria's rural economy. In view of this, non-banking activities are a welcome development since some of their approaches are proven to be knowledge enhancing and empowering for the rural population. Overall, community banks should attempt to strengthen non-banking approaches by collaborating more with self-help groups or nongovernmental organizations to be more empowering, results-oriented, and sustainable. Moreover, regulatory authorities should ensure that guidelines relate to credit application in terms of volume and sector allocation.  相似文献

After surgical treatment of an inguinal hernia, a 26-year-old male was discharged from hospital with a well healing surgical wound. Four weeks later he was admitted again with a major localized painful swelling of the soft tissues, whereas the clinical examination revealed no further local or systemic signs of inflammation. The immediate operation disclosed no abscess formation, but a large colliquation necrosis of the subcutaneous tissue with an outstanding petroleum-like odour. On toxicological examination of the necrotic tissue, a respective petroleum distillate was found. The patient was confronted with the suspicion of having injected the petroleum preparation himself to prolong the wound healing and finally admitted the self-mutilating behaviour. The pathophysiology, clinical history and morphological findings are discussed in comparison with case reports of chemically induced self-mutilation.  相似文献
