The purpose of this study was to describe process evaluation data including intervention fidelity, dosage, quality, participant responsiveness, and program reach for the Mothers And dauGhters daNcing togEther Trial (MAGNET) in Springfield, MA, in Spring 2013 and 2014. Seventy-six mother-daughter dyads were randomized to the mother-daughter group (CH-M, n = 28), the child-only group (CH, n = 25), or the health education group (CON, n = 23). CH-M consisted of 60 min of moderate-to-vigorous culturally-tailored dance classes for dyads. CH consisted of dance classes for the child. All groups received homework tutoring and weekly health newsletters. Process evaluation data were assessed at each intervention session (three days/week, 6-months) with semi-structured questionnaires by researchers. CH dance classes were slightly longer (58.2 ± 3.5 min) than CH-M (54.4 ± 5.5 min). In both groups, participants spent the majority of the dance intervention in light intensity physical activity (PA). Participants in the CH-M group enjoyed participating in MAGNET > 90% of the time. Mothers (92%) indicated that they wanted to continue dance as a form of PA. Mothers expressed that transportation, time commitment, and assessments were barriers to participation. Participants suggested future interventions should include longer intervention length and more communications between research staff and mothers. The MAGNET intervention matched the originally intended program in most aspects. A lower intervention dose was delivered to the CH-M group potentially due to barriers described by mothers. Because mother-daughter interventions have shown minimal effects on increasing PA, it is imperative that researchers utilize process evaluation data to shape future studies.
本研究旨在描述2013年春季和2014年春季在马萨诸塞州斯普林菲尔德开展的母女共舞试验（MAGNET）的过程评估数据，包括干预保真度、剂量、质量、参与者反应以及项目覆盖范围。76对母女二元组被随机分为母女组（CH-M，n = 28）、仅儿童组（CH，n = 25）或健康教育组（CON，n = 23）。CH-M组包括为二元组提供的60分钟中度至剧烈的文化定制舞蹈课程。CH组包括为儿童开设的舞蹈课程。所有组都接受家庭作业辅导和每周的健康通讯。研究人员通过半结构化问卷在每次干预课程（每周三天，为期6个月）时评估过程评估数据。CH组的舞蹈课程（58.2±3.5分钟）比CH-M组（54.4±5.5分钟）略长。在两组中，参与者在舞蹈干预中大部分时间进行的是轻度身体活动（PA）。CH-M组的参与者在超过90%的时间里享受参与MAGNET项目。母亲们（92%）表示她们希望继续将舞蹈作为一种身体活动形式。母亲们表示交通、时间投入和评估是参与的障碍。参与者建议未来的干预应包括更长的干预时长以及研究人员与母亲之间更多的沟通。MAGNET干预在大多数方面与最初计划的项目相符。由于母亲们描述的障碍，CH-M组的干预剂量较低。由于母女干预对增加身体活动的效果甚微，研究人员必须利用过程评估数据来指导未来的研究。
