The purpose of this study was to develop and validate a questionnaire for assessing parents' perception of their involvement in their children's tennis activity (Q‐PPICTA). The validation required four successive studies. In study 1, a preliminary version of the questionnaire was formulated after selecting and adapting items taken from existing questionnaires and interviews conducted with the parents of 36 young tennis players. Three factors for measuring parental involvement in sport were identified and retained: emotional, logistic, and informational supports. In study 2, exploratory factor analyses were performed on data collected from 214 parents of tennis players. Results attested the questionnaire's three‐factor structure and ascertained its internal consistency. In study 3, a confirmatory factor analysis as well as tests on convergent and discriminant validity were carried out on data gathered from a different sample of 220 parents of tennis players. Statistics confirmed the questionnaire's three‐factor structure and reliability. In study 4, the questionnaire's external construct validity was compared with another sample consisting of 192 parents and their children. Overall, results underlined satisfactory psychometric properties for the Q‐PPICTA. Nevertheless, further studies are required to confirm the questionnaire's accuracy, reliability, and temporal validity.  相似文献

目的 通过DWI及ADC值评价头穴针刺治疗家兔脑出血模型的疗效。方法 将60只家兔随机分为空白组(10只)、模型组(10只)、针刺组(40只);针刺组再随机分为留针组(10只)、手法组(30只),手法组根据针刺方法不同再随机分为透刺补法亚组、透刺泻法亚组和透刺平补平泻法亚组(各10只)。对模型组和针刺组于造模后2 h、3天、7天行DWI,测量血肿周围区域及对侧镜像区ADC值,并进行统计学分析;对部分家兔取脑组织进行病理检查。结果 脑出血后,血肿周围区域ADC值高于对侧镜像区,2 h、3天、7天ADC值差异有统计学意义。造模后2 h模型组和针刺组血肿周围区域ADC值较空白组升高;3天时模型组增长幅度大于针刺组;7天时模型组和针刺组ADC值有所回落,针刺组较模型组回降更为显著,手法组ADC值较留针组低,手法组各亚组间差异无统计学意义。对侧镜像区3天、7天的ADC值模型组与针刺组差异有统计学意义,而手法组各亚组间差异无统计学意义。结论 DWI可动态活体监测脑出血后脑组织水肿变化情况;头穴针刺治疗有助于缓解兔脑出血后脑水肿。  相似文献

Classification models for community-based rehabilitation (CBR) create conceptual order in the many types of rehabilitation programmes that exist in developing countries. Several models have been developed but none of the models appears to be widely accepted or being used in the evaluation process.

Purpose. To review classification models and assess its usability.

Methods. Literature review.

Results. Sixteen documents were found describing 11 different models. These models vary from simply listing different types of CBR to multidimensional configurations encircling principles, methods and outcomes of CBR. The models are only incidentally used in the evaluation of CBR programmes. The more recent models have been used to develop, select and group indicators.

Conclusions. Classification models can indeed structure the evaluation and comparison of CBR programs that are, by nature, very different from each other. Indicators can be developed within a theoretical framework provided by the classification model. In order to be widely accepted the models should be made less complex and focus on outcomes that are meaningful for the people involved in the evaluation as well as for policymakers and researchers.  相似文献

Purpose. To assess the relationship between participation and problems with participation in life situations, and life satisfaction in persons with late effects of polio.

Methods. One hundred fifty-eight persons with late effects of polio responded to a postal questionnaire including the Swedish versions of the Impact on Participation and Autonomy Questionnaire (IPA-S) and Life Satisfaction Questionnaire (LiSat-11).

Results. The persons' perceived participation in the five domains of participation in the IPA-S was significantly correlated with their satisfaction with life as a whole and with most of the 10 domains of life satisfaction. Significant differences in satisfaction with life as a whole and with eight of the 10 domains in LiSat-11 were found between groups of increasing severe problems with participation. Greater number of reports of severe problems with participation corresponded with gradually decreased satisfaction with life as a whole and with satisfaction in the eight domains in LiSat-11.

Conclusions. Perceived participation and problems with participation in life situations are determinants of life satisfaction in persons with late effects of polio. This implies that addressing participation and problems with participation in the rehabilitation of persons with late effects of polio may lead to an enhanced life satisfaction.  相似文献
