Toward a predictive model of suicidal ideation and behavior: some preliminary data in college students 总被引:4,自引:0,他引:4
Within a multivariate statistical design, the relationship of various interpersonal, emotional, and cognitive variables to suicidal ideation and behavior in college students was examined. A total of 158 subjects (58 males, 100 females) completed self-report measures of life stress, faulty cognitions, loneliness, depression, hopelessness, family cohesiveness, adaptive reasons for living, and suicidal ideation and behavior. The results of a multiple-regression analysis, forward-inclusion algorithm, indicated that a predictive equation consisting of loneliness, irrational beliefs, and low adaptive reasons for living best accounted for suicidal behavior scores. To determine the basic structures and power of the predictor variables under study, a factor analysis and composite regression were employed, resulting in a predictive equation consisting of three factors: Social/Emotional Alienation, Cognitive Distortions, and Deficient Adaptive Resources. Results are discussed in terms of an interactional model of suicidal behavior. 相似文献

The authors describe a cognitive-behavioral model for coping with stress that counselors can use as the basis for family assessment and personalized intervention. The model, assessment procedures, and appropriate counseling strategies are discussed. Translation of the model into clinical practice is examined with families of handicapped young children. A brief case study is provided to illustrate the model's usefulness for counselors. 相似文献

"A random sample of Mexican American women and a sample of family planning health care professionals, both from two major southwestern cities in the United States, were compared in terms of their reports of birth control methods used, problems in obtaining family planning services, and values involved in making fertility-related decisions, within the Mexican American population.... While there were points of agreement between the two samples, discrepancies were found in reports of problems in obtaining family planning services, fertility-related values, and in the acceptability of female sterilization as a birth control method. It was concluded that family planning professionals in these service areas tend to stereotype Mexican American women, and may not yet realize that the family planning attitudes and behavior of these women are probably changing in significant ways."

The theoretical basis for the repetition of themes in related groups is addressed by describing similar processes in four systems: inpatient psychiatric ward, inpatient psychotherapy group, supervisory group, and group psychotherapy division. The principles of general system theory help explain process parallels in allied groups and illuminate group process. 相似文献

Daily life events were grouped according to their life content area and according to the desirability of the event as rated by the subject. Associations among event groupings and concurrently measured daily mood were examined. As in studies of major life events, some event classifications were more strongly associated with mood than were others: Specifically, desirable family-leisure events and undesirable work events were strongly related to mood. The results suggests that particular life areas deserve special attention in understanding environmental stress. 相似文献

The results of an evaluation of the perfusion scintigraphy findings of 350 hospitalised neurological patients and 55 more strictly selected neurosurgical patients with cerebrovascular complaints, revealed an accuraty of 83%, a sensitivity of 89%, and a specificity of 83%. The selection of the patients had no influence on the results as a whole. Compared with contrast-medium angiography, incorrect diagnosis must be expected in 17% of the cases. This includes erroneous negative findings in 10% of the cases. Grounds for misinterpretations are suggested, and the biological and methodological limitations of the method are set forth. 相似文献
