ABSTRACT

The purpose of this systematic review was to examine if the motives of satisfaction with outcomes, enjoyment of behavior, self-determination, and identity are related to physical activity (PA) maintenance in older adults. We also explored whether the strength of these associations varies as a function of sample characteristics (i.e., age, gender, physical health status) and maintenance context. Five electronic databases (PubMed, PsycINFO, SportDiscus, CINAHL, and ProQuest Dissertations and Theses) were searched, and sixteen studies (k) with a sample mean age ≥ 55 years were included. When the number of studies was ≥ 5 for a given motive, a pooled correlation coefficient was calculated using the inverse-variance method under the random-effects model assumption. Self-determination was positively associated with PA maintenance [r (95% CI) = 0.189 (0.127, 0.249); k = 11]. This association was stronger and more homogeneous for samples described as having a physical health condition (r = 0.212; k = 6) and studies judged to be at risk of bias due to missing data (r = 0.223; k = 8). Few studies (< 5) investigated satisfaction with outcomes, enjoyment of behavior, and identity, which precludes any summary judgment for these three motives.

摘要

该系统评价的目的是检查对结局满意，行为享受，自决和认同的动机是否与老年人的体育锻炼（PA）维持有关。我们还探讨了这些关联的强度是否随样本特征（即年龄，性别，身体健康状况）和维持环境的变化而变化。搜索了五个电子数据库（PubMed，PsycINFO，SportDiscus，CINAHL和ProQuest学位论文），并进行了十六项研究（k）的样本平均年龄≥55岁。对于给定的动机，当研究数量≥5时，在随机效应模型假设下，使用逆方差方法计算合并的相关系数。自我决定与PA维持呈正相关[ r（95％CI）= 0.189（0.127，0.249）；k  = 11]。对于描述为患有身体健康状况的样本，该关联更强且更均匀（r  = 0.212；k  = 6），并且由于缺少数据，研究被认为存在偏见风险（r  = 0.223; k = 8）。很少有研究（<5）对结果的满意度，行为的愉悦性和认同感进行调查，这排除了对这三个动机的任何简要判断。PROSPERO注册号：CRD42018088161。
