Reports an error in the original article by G. E. Good et al (Journal of Counseling Psychology, 1995 [Jan], Vol 42 [1], 3-10). On page 6, the numbers on line 2 for the Tucker-Lewis fit index should be .827 (Sample 2) and .830 (Sample 3). (The following abstract of this article originally appeared in record 1995-15746-001.) Two distinct deficits in research on male gender role conflict are addressed: (a) lack of psychometric information and (b) lack of research involving clinical samples. First, using 1,043 men across 3 samples, the psychometric properties of the Gender Role Conflict Scale (GRCS) were examined through confirmatory analyses, internal consistency estimation, and construct validation. Next, using 130 male university counseling center clients across 2 samples, the relation between gender role conflict and psychological distress was examined. The GRCS demonstrated good internal consistency and was best modeled as 4 intercorrelated factors, as originally proposed by J. M. O'Neil, B. Helms, R. Gable, L. David, and L. Wrightsman (1986). Construct validity was supported through correlations with attitudes about masculinity, fear of intimacy, and social desirability in expected directions. However, male gender role conflict was significantly related to psychological… (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Using a sample of hospital nurses, the author tested the hypothesis that both self-efficacy and perceived control over decision making contribute to individuals' willingness to engage in reformist dissent when faced with injustice and to their intentions to exit. Reformist dissent is defined as dissent that occurs within the confines of an organization's rules and norms. Perceived control over decision making was expected to be positively related to willingness to engage in reformist dissent and to be inversely related to exit. Because it was expected that both dissent and exit require confidence, self-efficacy was predicted to be positively related to both dissent and exit. Control was positively related to willingness to dissent and inversely related to exit. Self-efficacy, however, predicted only dissent. Implications for worker well-being and retention are discussed, and directions for future research and theory development are offered.

Presents 3 different studies of in-session changes in emotionally focused couples therapy (EFT). Studies of in-session conflict events demonstrate both that couples' conflict interaction at the end of treatment is more affiliative and interdependent than at the beginning of treatment, and that peak session conflict interaction is deeper in level of experience and more affiliative than the interaction in poor session conflict episodes. In addition, events beginning with intimate, affective self-disclosure by one partner were found to involve greater affiliation in spouses' responses to the self-disclosure than in a control event not involving self-disclosure. The possible change processes in EFT are discussed in light of these results. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

Recently parasitoids were hypothesized to encounter a reliability-detectability problem relating to chemical stimuli from the first and second trophic level, when searching for hosts. The relative role of infochemicals originating from the host,Pieris brassicae (second trophic level), and its food plant, cabbage (first trophic level), have been investigated with respect to long-range host location by the larval parasitoidCotesia glomerata. Flight-chamber dual choice tests showed that uninfested cabbage plants are least attractive to female wasps. Host larvae and their feces were more attractive than clean plants but far less attractive than artificially damaged and herbivore-damaged plants. The plant-host complex, with host larvae actively feeding on the plant, was the most attractive odor source for the parasitoids. The data indicate that one of the solutionsC. glomerata uses to solve the reliability-detectability problem is to respond to infochemicals that are emitted from herbivore-damaged plants. Whether these infochemicals are herbivore-induced synomones that are produced by the plant remains to be demonstrated. Infochemicals emitted by the herbivore or its by-products are of little importance in the foraging behavior ofC. glomerata.  相似文献

In a longitudinal study of 253 bereaved adults, people with poorer social support, more concurrent stressors, and higher levels of postloss depression reported more rumination than people with better social support, fewer stressors, and lower initial depression levels. Women reported more rumination than men. People with a ruminative style at 1 month were more likely to have a pessimistic outlook at 1 month, which was associated with higher depression levels at 6 months. People with a more ruminative style were more depressed at 6 months, even after controlling for initial depression levels, social support, concurrent stressors, gender, and pessimism. Additional stressors and high depression scores at 1 month were also associated with higher levels of depression at 6 months. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献
