目的:本研究旨在考察舞动团体对大学生心理健康的影响作用。方法:将随机选取的46名大学本科生分为实验组(23人)和对照组(23人,有3人后测数据流失)。实验组被试接受连续10周,每周2小时的舞动团体辅导,对照组被试不接受任何处理。使用《一般生活满意度量表》、《抑郁量表》、《积极建构问卷》对两组被试进行前后测。结果:实验组和对照组被试在前测的各指标上差异不显著,在后测的各指标差异显著。组内差异检验结果显示,实验组被试的一般生活满意度后测显著高于前测(t=3.347,P0.005),抑郁水平后测显著低于前测(t=-4.217,P0.001),积极建构分数后测显著高于前测(t=4.954,P0.001);而对照组被试在各指标上的前后测差异不显著。结论:舞动团体能显著增强大学生对事物的积极建构,降低大学生的抑郁水平,提高大学生的总体生活满意度。  相似文献

Objective:

translate and validate to Portuguese the Scale of Student Satisfaction and Self-Confidence in Learning.

Material and Methods:

methodological translation and validation study of a research tool. After following all steps of the translation process, for the validation process, the event III Workshop Brazil - Portugal: Care Delivery to Critical Patients was created, promoted by one Brazilian and another Portuguese teaching institution.

Results:

103 nurses participated. As to the validity and reliability of the scale, the correlation pattern between the variables, the sampling adequacy test (Kaiser-Meyer-Olkin) and the sphericity test (Bartlett) showed good results. In the exploratory factorial analysis (Varimax), item 9 behaved better in factor 1 (Satisfaction) than in factor 2 (Self-confidence in learning). The internal consistency (Cronbach''s alpha) showed coefficients of 0.86 in factor 1 with six items and 0.77 for factor 2 with 07 items.

Conclusion:

in Portuguese this tool was called: Escala de Satisfação de Estudantes e Autoconfiança na Aprendizagem. The results found good psychometric properties and a good potential use. The sampling size and specificity are limitations of this study, but future studies will contribute to consolidate the validity of the scale and strengthen its potential use.  相似文献

Objective

To describe the relationship between caregiver-specific support and conflict, and psychosocial outcomes among individuals experiencing their first dysvascular lower extremity amputation (LEA).

Design

Cross-sectional cohort study using self-report surveys.

Setting

Department of Veterans Affairs, academic medical center, and level I trauma center.

Participants

Individuals undergoing their first major LEA because of complications of peripheral arterial disease (PAD) or diabetes who have a caregiver and completed measures of caregiver support and conflict (N=137; 94.9% men).

Interventions

Not applicable.

Main Outcome Measures

The Patient Health Questionnaire-9 to assess depression and the Satisfaction With Life Scale to assess life satisfaction.

Results

In multiple regression analyses, controlling for global levels of perceived support, self-rated health, age, and mobility, caregiver-specific support was found to be associated with higher levels of life satisfaction and caregiver-specific conflict was found to be associated with lower levels of life satisfaction and higher levels of depressive symptoms.

Conclusions

The specific relationship between individuals with limb loss and their caregivers may be an important determinant of well-being. Conflict with caregivers, which has received little attention thus far in the limb loss literature, appears to play a particularly important role. Individuals with limb loss may benefit from interventions with their caregivers that both enhance support and reduce conflict.  相似文献

Objectives

To investigate the relation of gait training (GT) during inpatient rehabilitation (IPR) to outcomes of people with traumatic spinal cord injury (SCI).

Design

Prospective observational study using the SCIRehab database.

Setting

Six IPR facilities.

Participants

Patients with new SCI (N=1376) receiving initial rehabilitation.

Interventions

Patients were divided into groups consisting of those who did and did not receive GT. Patients were further subdivided based on their primary mode of mobility as measured by the FIM.

Main Outcome Measures

Pain rating scales, Patient Health Questionnaire Mood Subscale, Satisfaction With Life Scale, and Craig Handicap Assessment and Reporting Technique (CHART).

Results

Nearly 58% of all patients received GT, including 33.3% of patients who were primarily using a wheelchair 1 year after discharge from IPR. Those who used a wheelchair and received GT, received significantly less transfer and wheeled mobility training (P<.001). CHART physical independence (P=.002), mobility (P=.024), and occupation (P=.003) scores were significantly worse in patients who used a wheelchair at 1 year and received GT, compared with those who used a wheelchair and did not receive GT in IPR. Older age was also a significant predictor of worse participation as measured by the CHART.

Conclusions

A significant percentage of individuals who are not likely to become functional ambulators are spending portions of their IPR stays performing GT, which is associated with less time allotted for other functional interventions. GT in IPR was also associated with participation deficits at 1 year for those who used a wheelchair, implying the potential consequences of opportunity costs, pain, and psychological difficulties of receiving unsuccessful GT. Clinicians should consider these data when deciding to implement GT during initial IPR.  相似文献

Objective

To identify important sources of distress among burn survivors at discharge and 6, 12, and 24 months postinjury, and to examine if the distress related to these sources changed over time.

Design

Exploratory.

Setting

Outpatient burn clinics in 4 sites across the country.

Participants

Participants who met preestablished criteria for having a major burn injury (N=1009) were enrolled in this multisite study.

Interventions

Participants were given a previously developed list of 12 sources of distress among burn survivors and asked to rate on a 10-point Likert-type scale (0=no distress to 10=high distress) how much distress each of the 12 issues was causing them at the time of each follow-up.

Main Outcomes Measures

The Medical Outcomes Study 12-Item Short-Form Health Survey was administered at each time point as a measure of health-related quality of life. The Satisfaction With Appearance Scale was used to understand the relation between sources of distress and body image. Finally, whether a person returned to work was used to determine the effect of sources of distress on returning to employment.

Results

It was encouraging that no symptoms were worsening at 2 years. However, financial concerns and long recovery time are 2 of the highest means at all time points. Pain and sleep disturbance had the biggest effect on ability to return to work.

Conclusions

These findings can be used to inform burn-specific interventions and to give survivors an understanding of the temporal trajectory for various causes of distress. In particular, it appears that interventions targeted at sleep disturbance and high pain levels can potentially effect distress over financial concerns by allowing a person to return to work more quickly.  相似文献
