This pilot study assessed possible changes in Life Satisfaction across three generations of women after a 6-mo. physical activity intervention. The primary purpose of the study was to test the study design and discover critical issues that should be controlled for or changed in a follow-up study. A quasi-experimental design was used to assign randomly a convenience sample of participant triads into two groups: a home-based group (n=27) and a control group (n=9). Daughters were pre-menarcheal (n=13, M=10.1 yr., SD=1.5), mothers were premenopausal (n=13, M=37.2 yr., SD=4.2), and grandmothers were postmenopausal (n=11, M=61.5 yr., SD=4.4). Life Satisfaction was measured using the Satisfaction with Life Scale. Participation in physical activity was measured using the Physical Best Physical Activity Questionnaire and a pedometer to count the number of steps taken per day. Compared with the control group, participants in the home-based group generally increased physical activity but their scores for Life Satisfaction did not increase. Recommendations concerning the study design, reducing limitations, and hypotheses for further study are given.
这项试点研究评估了经过6个月体育活动干预后三代女性生活满意度可能发生的变化。该研究的主要目的是测试研究设计，并发现后续研究中应加以控制或改变的关键问题。采用准实验设计，将一个方便样本的参与者三元组随机分为两组：居家组（n = 27）和对照组（n = 9）。女儿们处于月经初潮前（n = 13，M = 10.1岁，标准差 = 1.5），母亲们处于绝经前（n = 13，M = 37.2岁，标准差 = 4.2），祖母们处于绝经后（n = 11，M = 61.5岁，标准差 = 4.4）。使用生活满意度量表来测量生活满意度。使用“体育最佳”体育活动问卷和计步器来测量体育活动参与情况，以计算每天的步数。与对照组相比，居家组的参与者总体上增加了体育活动，但他们的生活满意度得分并未提高。文中给出了有关研究设计、减少局限性以及进一步研究假设的建议。
