The present study was conducted to examine the hypothesis that compliant chronically ill patients, typically described as adjusted, reinforce more positive social environments using behavioral controls than noncompliant patients, typically described as maladjusted. Specifically, it is hypothesized that diet-compliant chronic hemodialysis patients emit significnatly more active involvement-in-treatment behaviors and more social behaviors than diet-noncompliant chronic hemodialysis patients. Subjects, who ranged in age from 30 to 77 years, were outpatients at a kidney center. Behavioral observations were conducted to assess the occurrence or frequency of (1) four involvement-in-treatment behaviors that are routinely taught to all patients and (2) two social behaviors, which were patient verbalizations and smiles. The results showed that compliant patients emitted significantly more involvement-in-treatment behaviors and smiles than noncompliant patients. Results support the proposed control framework that compliant, in contrast to non-compliant, chronically ill patients have recourse through positive behavioral controls when adjusting to the stresses of illness. It was proposed that through these controls, compliant patients reinforce positive environments rather than simply respond to life circumstances as given.  相似文献

Several theories have been presented that predict differences between women and men in attitudes toward the environment due to differences in sex roles. Research on which these theories can be tested has tended to examine general environmental concern, and the results have generally been weak and inconclusive. Using an approach suggested in the literature, this study examines sex differences in concern and knowledge, using multi-item scales for each, about one environmental issue — acid rain. The results contradict the theories being tested, however: if there is a sex difference, men are found to be more concerned and knowledgeable about the environmental problem.  相似文献

We developed the Sheltered Care Environment Scale (SCES) to provide researchers and practitioners with a practical means of assessing the social climate in congregate residential settings for the elderly. The SCES, a 63-item yes/no questionnaire that can be completed by residents and staff members of a facility, taps their perceptions of seven dimensions of the social environment. These dimensions concern the quality of relationships, the personal growth orientation present in the facility, and maintenance and change of the social system. The SCES discriminates among settings, has moderate to high internal consistency and split-half reliability, and is sensitive to environmental change against a backdrop of relative stability over time. The SCES reflects actual, agreed-on qualities of a setting and is relatively unaffected by characteristics of the respondent. Normative data are available from a national sample of 244 facilities representing the variety of residential settings available to the elderly.  相似文献

A total of 45 subjects in three age groups (younger, middle-age, older) were trained to word process on microcomputers using a commercial training program and an experimenter-designed test and evaluation protocol. Although all of the subjects mastered the essentials of word processing, the older group took significantly longer to complete the training and evaluation procedures and performed more poorly on a review examination that tested their knowledge of the word-processing commands and techniques. The results are discussed in relation to requirements for trainer assistance, motivational factors, and the need to design training protocols that meet the needs of older adults.  相似文献

I hypothesized that feelings of strain experienced by an adult daughter are likely to interfere with the nature of her relationship with her aging mother and to have a potentially deleterious effect on the mother. To test this proposition, I devised a study that examined the impact of two brief interventions on 37 middle-aged women and 24 of their elderly mothers: (a) a cognitive-behavioral presentation designed to reduce the daughter's unrealistic feelings of responsibility and (b) a supportive-educational presentation designed to increase the daughter's awareness of her mother's needs. I found that the first procedure was more effective than the second in reducing the daughter's burden, improving the mother-daughter relationship, and decreasing the loneliness experienced by the elderly mother.  相似文献

We compared the effect of two approaches, family counseling and support groups, for relieving the stress and burden experienced by care givers of dementia patients. Both treatments are designed to implement features of a stress-management model that have been identified in prior research with this population: providing information about the patient's disease and its effects on behavior, teaching behavioral problem solving for managing difficult behavior, and identifying potential support for care givers. Subjects were primary care givers of dementia patients living in the community; they included husbands, wives, daughters, and other relatives. Although subjects in the treatment groups made significant gains over time, they did not differ from wait-list subjects who showed similar improvements. One-year follow-up interviews indicated that gains made during the treatment period were maintained.  相似文献

We examined potential differences between two matched subgroups of elderly men: young-old (65-74 years of age; n = 53) and old-old (75 years of age and older; n = 56). Subjects were fairly healthy men from community agencies, who were interviewed and tested on a number of characteristics involving personality, mood, attitudes, and behaviors. Although t tests and correlations indicated some differences between the groups, the overall findings underlined their similarity on the vast majority of variables scrutinized. The crucial base for enhancing understanding in gerontology should not only focus on the age-advancing senescent person but on the whole individual.  相似文献

The authors describe a career counseling strategy based on specific psychosocial characteristics of battered women. The approach is developmental in nature, focusing on the client's self-concept. A group format based on a pilot intervention is proposed to assist battered women in developing appropriate life and career decision-making skills.  相似文献
