The purpose of this study was to evaluate the effects of a 9-week supervised multicomponent exercise program on functional fitness and body composition in independent older adults. Forty-two adults age 60-86 years were randomly assigned to an exercise or a control group and were evaluated before and after training. The training program consisted of 3 sessions of walking, strengthening, and flexibility exercises per week. The multicomponent training program resulted in significant (p < .005) improvements on the chair stand, arm curl, 6-min walk, and up-and-go tests. The findings of this study indicate that a 9-week training program increased upper and lower body strength, aerobic endurance, and agility/dynamic balance in older adults. The most affected components of functional fitness were lower body strength and aerobic endurance. There was no effect of the 9-week training on body composition.  相似文献

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.  相似文献

The use of addictive substances is undergoing moralization in American society-behaviors once viewed as personal preferences now carry moral significance. Research has shown that sociomoral emotions like guilt, thought to be reflective of one's internalized standards and societal mores, can be an important influence on behavior. The present study explored the relationship between college students' self-reports of adolescent substance use (cigarettes, alcohol, and marijuana) and scores on indices tapping different aspects of guilt (Standards, Situational, and Chronic Guilt). Participants were 230 undergraduate students (mean age = 19; 55 percent female; 69 percent White). Substance users had lower scores on Standards and Situational Guilt than non-users, but no difference was observed in Chronic Guilt. The present results suggest that a stronger internalization of societal standards, as reflected by higher scores on Standards and Situational Guilt, may prove a useful tool in the prevention of substance use.  相似文献

This study examined the association between the therapeutic alliance in family therapy and changes in symptom distress, interpersonal relationships, and family coping. The participants (N = 81) were members of low socioeconomic status families referred to a university clinic for in-home family therapy. Participants completed the Outcome Questionnaire, Family Crisis Oriented Personal Evaluation, and the Family Therapy Alliance questionnaires. Regression analyses revealed that the therapeutic alliance explained 19% of the variance in symptom distress changes for mother, 55% for fathers, and 39% for adolescents. The implications of these findings for practicing and researching family therapy are presented.  相似文献

Partial privatization of Social Security is being considered as an integral part of the future Social Security program for American retirees. Because privatization creates uncertainty about the amount of retirement income that future retirees may expect to receive, the issue of a safety net is critical. This article presents the findings from an empirical study that investigated the degree to which the current Social Security and Supplemental Security Income (SSI) programs provide a safety net, separately and in combination, to the elderly poor. The major findings were that the Social Security program not only increases the income statuses of both posttransfer and pretransfer poor elderly people considerably, but that the program also significantly equalizes the distribution of income among them. In addition, the SSI program supplements the Social Security program in establishing an even greater safety net, especially for posttransfer poor elderly people. On the other hand, Social Security benefits make the income disparity among races greater between both posttransfer and pretransfer poor elderly people. Implications for policy are discussed.  相似文献

An increasing number of aging community providers and consumers support consumer-direction (CD) in long-term care services. In regard to devolution, consumer-direction goes beyond the usual approach of shifting responsibilities from the federal government to state governments to bring programs "closer to the people." Consumer-direction goes even further by placing resources directly in the hands of consumers. Yet, many questions remain unanswered regarding how to implement CD personal assistance services in general, and especially for older persons. This article describes the importance of examining views from multiple key stakeholders involved in implementing CD programs. We report on three background studies that have informed the Cash and Counseling Demonstration and Evaluation (CCDE) design and implementation-policy expert interviews as well as surveys and focus groups with consumers and representatives. As a fourth data source, we drew upon experiences in designing the CCDE and initial results from the first year of implementation. Each of the three studies on its own provided essential information for planning the CCDE. However, when we examined the studies together, and added CCDE design and implementation experiences, views expressed by the different stakeholders formed a type of multi-perspective "dialogue" that expanded our knowledge about implementing CD services. We hope this increased knowledge will help expand the availability of such services for consumers of any age who want to direct their own care.  相似文献
