The study was designed to examine the influence of significant others (mothers, fathers, and male and female peers) on continuing involvement in sport by adolescent females. Survey data were collected from 376 girls using a forced-choice, self-administered questionnaire. Maintenance of involvement was measured by the proportion of possible years in which the respondents were involved in physical activity within each of three participation contexts (intramural, interschool, and community sport). Several indicators of significant other influence were used. The degree to which involvement in physical activity is maintained is positively related to the source, amount and type of influence received from significant others, and varied by the participation context. Overall, the socializing influence of significant others was able to account for 11% of the variance in intramural activity, 20% of the variance in interschool sport, and 10% of the variance in community-based activity.This study was funded by a grant from Fitness Canada.  相似文献

Dependency, self-criticism, and depressive attributional style   总被引:1,自引:0,他引:1  
Dependency and self-criticism have been proposed as independent factors in depression. Investigated whether depressive individuals characterized by dependency and self-criticism, respectively, differ with regard to internality of causal attributions for negative events. Sixty psychiatric outpatients completed the Depressive Experiences Questionnaire, the Beck Depression Inventory, the semantic differential, and the Attributional Style Questionnaire. Dependency and self-criticism correlated positively with internality and with each other (p less than .0001). Findings did not support the specificity of dependency and self-criticism as subtypes of depression.  相似文献

The revised Beck Depression Inventory (BDI) was administered to 174 male and 276 female psychiatric outpatients diagnosed with affective disorders. The mean BDI scores, mean number of symptoms claimed, and corrected item-total correlations were comparable for both sexes, and the coefficient alpha for each sex was .88. Principal components analyses found four dimensions of depression underlying both sexes' BDI item-intercorrelation matrices. Although men and women had comparable dimensions with respect to weight loss, self-blame, and somatic-performance symptoms, men had affective and performance symptoms loading on the same factor, whereas women had affective and cognitive symptoms loading on the same dimension.  相似文献

Probability of relapse after recovery from an episode of depression   总被引:2,自引:0,他引:2  
Examined relapse rates in those individuals who have experienced an episode of unipolar depression as a function of the number of previous episodes, gender, age at onset of the episode (less than 40 vs. greater than 40), time since a previous episode, and depression level at time of interview. From of 6,742 participants, 2,046 were interviewed; of these, 1,130 had at least one, 513 reported a second and 173 reported a third episode. The probability for relapse was positively related to number of previous episodes, being female, depression level at time of interview, but not to age at onset (less than 40 vs. greater than 40). Women were also more likely to have more severe episodes. Participants with elevated depression symptoms reported a greater number of previous episodes. Following the first episode, there was a decline in hazard rate for men but not women; following the second episode, there was no change in vulnerability for men; for women, the results were ambiguous.  相似文献

This paper demonstrates a method of transferring research data from a remote clinic to a large university mainframe for data manipulation and statistical analysis. Data collected by an Apple //e computer were transferred to an IBM 3031 mainframe by sending data files to an IBM PC by telephone modem or by direct hardwire connection to the PC. The IMB PC performed data-formatting routines and then uploaded the files to the mainframe for storage. Advantages and disadvantages of sending data over telephone lines via a modem are discussed.  相似文献
