这项研究比较了两种低成本干预措施对体力活动采用的效率。通过报纸广告招募的久坐不动的成年人（N = 194）被随机分配接受动机匹配的，个性化的干预（IT）或标准的自助干预（ST）。评估和干预措施在基线、1个月、2个月、3个月和6个月时通过重复邮寄进行。对参与者进行了评估，包括当前的身体活动行为，采取定期身体活动的动机准备，以及与身体活动参与相关的心理结构（例如自我效能，决策平衡）。重复测量方差分析（ANOVA）显示，两组在基线和六个月之间的体力活动参与显着增加，其中IT参与者的增加幅度更大。IT组在所有主要结局指标上均优于ST组：（a）每周身体活动分钟数，（B）达到疾病控制中心和美国运动医学学院（CDC/ACSM）推荐的最低身体活动标准，（c）达到身体活动的动机准备行动阶段。两组在基线和6个月之间，与体力活动采用相关的心理结构（例如自我效能）都有显著改善，治疗组之间没有观察到显著差异。利用计算机专家系统和自助手册，提供个性化的，动机匹配的干预措施似乎是一种有效的，低成本的方法，提高身体活动的参与在社区。
This study compared the efficiency of two low-cost interventions for physical activity adoption. Sedentary (N = 194) adults recruited through newspaper advertisements were randomised to receive either a motivationally-matched, individually-tailored intervention (IT) or a standard self-help intervention (ST). Assessments and interventions were delivered by repeated mailings at baseline, one, two, three, and six months. Participants were assessed regarding current physical activity behavior, motivational readiness to adopt regular physical activity, and psychological constructs associated with physical activity participation (e.g. self-efficacy, decisional balance). Repeated measures analyses of variance (ANOVAs) revealed significant increases in physical activity participation between baseline and six months for both groups with a significantly greater increase among IT participants. The IT group outperformed the ST group on all primary outcome measures: (a) minutes of physical activity per week, (b) reaching Centers for Disease Control and American College of Sports Medicine (CDC/ACSM) recommended minimum physical activity criteria, and (c) achieving the Action stage of motivational readiness for physical activity adoption. Both groups showed significant improvement between baseline and six months on the psychological constructs associated with physical activity adoption (e.g. self-efficacy), with no significant differences observed between the treatment groups. Utilizing computer expert systems and self-help manuals to provide individually-tailored, motivationally-matched interventions appears to be an effective, low-cost approach for enhancing physical activity participation in the community.
