This study investigated the relationship between acquisition of psychoeducational principles and symptomatic improvement in depressed in-patients. One hundred and twenty-three inpatients hospitalized on a Cognitive Therapy Unit were administered the Test of Cognitive Behavioral Principles (TCBP) and the Beck Depression Inventory at admission and discharge. It was predicted that the TCBP scores would be higher at discharge than at pre-testing at admission. Further, it was hypothesized that the higher TCBP scores at post-test would be significantly correlated with lower Beck Depression Inventory scores at post-test. The results revealed that inpatients' TCBP scores improved over the course of treatment supporting the first hypothesis. However, the data did not support the second hypothesis as there was not a significant relationship between the TCBP scores and the BDI scores at discharge. The results are discussed in terms of clinical, theoretical, and methodological implications. 相似文献

Conlon and Garland (1993) demonstrated that information about the degree of project completion, as compared with information about sunk costs, seemed to be the driving force behind continued investment in an R&D project. In the present paper, we replicate and extend this work. In studies with experienced bank managers, Chinese graduate students, and advanced-level MBA students, we find overwhelming support for the importance of project completion on investment intentions, with no indication of typical sunk cost effects. We argue that our results support a goal substitution explanation for many escalation phenomena where, as progress moves forward on a project, completion of the project itself takes increasing precedence over other goals (e. g., economic profit) that may have been more salient at the time the project was initiated. 相似文献

As researchers become more interested instudying the influences of the male gender role onpeople's physical and psychological well-being, measuresof several male role domains have been created,including psychological agency, traditional attitudestowards men, and masculine gender role stress (MGRS).These measures of the male gender role, however,typically have been constructed and validated using only samples of men. This restriction introducesquestions about the reliability and validity of theseinstruments in samples of women, leading to problemswhen generalizing findings to this group. The present study addressed these issues by examining thefactor structure, factor correlations, and latent meansof these three male role measures for a sample of mostlyCaucasian men and women, using multiple group confirmatory factor analytic techniques.Results showed only the dimensionality of the agenticpersonality traits differed significantly for men andwomen. The interrelationships among and latent means of agency, attitudes, and MGRS differed by sex.These findings demonstrate the utility of the currentconceptualization of sex and gender; in other words,that gender is not totally determined by sexand that men and women internalize many of the samegender cues, but differentially endorse them to varyingdegrees. 相似文献

Subjects were 288 adolescents and adults with end-stage renal disease who were candidates for kidney transplantation, a group identified at risk for noncompliance. The purpose was to examine racial and ethnic variations in coping—variables that may underlie noncompliance and impact upon health outcome. Secondarily, the relationship between depression and particular styles of coping was investigated. Race/Ethnicity was divided into three categories: Black/Non-Hispanic, White/Non-Hispanic, and Hispanic. Coping and depression were assessed using the COPE and Beck Depression Inventory, respectively. Results indicated that Hispanic and Black subjects were more likely to use maladaptive styles of coping and less likely to use adaptive coping than were White subjects and that Black subjects reported more physical symptoms of depression. These findings point to possible mechanisms underlying the occurrence of noncompliance and resulting poorer health outcome for individuals of different racial and ethnic groups. 相似文献

A comprehensive four-factor interactive model on physical, psychological, and environmental processes related to the sense of control is presented for adult development with an emphasis on later life. The four experienced components are (1) control from within oneself, (2) control over oneself, (3) control over the environment, and (4) control from the environment. Control over oneself and over the environment measure self-directed control, while control from within oneself and from the environment measure nonself-directed control. Coping (a bidimensional control scale) measures control from powerlessness and suicide to overcontrolling. Findings confirm a significant loss of coping in an older cohort group from a white, rural sample composed primarily of single subjects with low coping representing a significant drop in self-directed behavior. A discussion of the relationship between self-direction and health in the older cohort group follows. 相似文献

The effects of changes in context on recognition memory were investigated in two experiments. In Experiment 1 target items were embedded in congruous or incongruous sentence frames and then tested in the original, new congruous, or new incongruous contexts. Experiment 2 included a third encoding condition; targets were also embedded in abstract definitional sentences. Both experiments revealed a reliable crossover interaction between the initial encoding condition and the mode of the changed context. Congruous items were recognized better in new congruous contexts, whereas incongruous items were recognized better in new incongruous contexts. Recognition of definitional items was equally impaired by both context changes. The results suggest the importance of the symmetry between acquisition and test encoding dimensions. These experiments also point out the need to distinguish between different ways in which the concept “integration” is used in current research. 相似文献

Because previously-attempted methods of increasing automobile seat belt usage have proven to be either ineffective or unworkable, a series of field experiments was carried out to test a technique of behavior influence utilizing a modest, positive incentive. In three separate studies, seat belt use of 4,745 drivers was observed as they drove out of a parking lot, after receiving one of several safety reminder leaflets. Some versions of the leaflet offered a gift certificate to a certain proportion of drivers who wore seat belts; other versions offered no incentive. The results showed that an incentive, regardless of the probability of payoff, raised belt use from about 15% to nearly 40%. Implications for future research and applications are discussed. 相似文献
