DESCRIPTION (provided by applicant): Obesity runs in families - spouses enter marriage with similar weight statuses, gain weight together over time and model obesogenic behaviors for their children. Many energy balance decisions are made in the home and this important social/interpersonal environment can either help or hinder weight management. Ecological models of obesity recognize the impact of the home and larger environment contexts on weight, however, existing treatment models remain individual-focused. Weight loss outcomes might be improved by expanding the focus of treatment from the individual to the marital dyad, targeting joint behavior change and the creation of an interpersonal milieu that supports long-term behavior change. According to Self Determination Theory, greater autonomous self-regulation of behaviors and subsequently better treatment outcomes are observed when individuals have important others in their lives who provide an environment in which personally meaningful choice is supported and criticism and control are minimized. Previous research including our own ongoing work suggests that increases in autonomy support from important others are associated with increases in autonomous self-regulation for weight loss and that these changes in autonomous self-regulation are indeed associated with weight loss outcomes. Additional research is needed to establish causal links and to develop and test interventions designed to facilitate the autonomy supportive behavior of significant others in the home environment. This theoretically based approach has tremendous potential to add to the modest effects found in the published literature on the involvement of spouses in weight loss treatment. The proposed study is a randomized controlled trial testing a couple's intervention based on Self Determination Theory that is designed to change the social context of weight loss by training spouses to provide autonomy support for each other's eating and physical activity behavior change. Sixty-four couples will be randomized to either 6 months of treatment based on SDT (SDT-WL) or to 6 months of treatment based on behavioral theory (BWL). Couples will attend weekly sessions for 6 months and will be assessed at 0, 6, and 12 months. We predict that by bolstering autonomy support, SDT-WL will increase autonomous self-regulation and perceived competence and will produce greater weight loss and maintenance than standard behavioral treatment. The study focuses on couples rather than individuals, is theoretically based, focusing on autonomy support and distinguishing this from other types of support, and directly trains partners in such supportive behaviors. If successful, we will seek funding to test the SDT approach in a larger trial with a longer follow-up period.

描述（由申请人提供）：肥胖症在家庭中运行 - 配偶以相似的体重状态进入婚姻，随着时间的流逝，体重增加并为子女建模肥胖行为。在家庭中做出许多能源平衡决策，这种重要的社会/人际环境可以帮助或阻碍体重管理。肥胖的生态模型认识到房屋和更大的环境环境对体重的影响，但是，现有的治疗模型仍然以个人为中心。通过将治疗的重点从个人扩展到婚姻二元组，针对共同行为的变化以及支持长期行为改变的人际关系，可以改善减肥结果。根据自我确定理论，当个人在生活中拥有重要的其他人时，会观察到对行为的更大自主自治自我调节，随后可以观察到更好的治疗结果，这些人提供了一个支持个人有意义的选择的环境，并将批评和控制降至最低。以前的研究包括我们自己正在进行的工作，表明，重要其他工作的自主支持的增加与自主体重减肥的自治自我调节有关，并且自主性自我调节的这些变化确实与减肥结果有关。需要进行其他研究来建立因果关系，并开发和测试旨在促进家庭环境中其他重要行为的自主支持行为的干预措施。这种基于理论上的方法具有巨大的潜力，可以增加有关配偶参与减肥治疗的发表文献中的适度效应。拟议的研究是一项随机对照试验，基于自我确定理论，旨在通过训练配偶来改变体重减轻的社会背景，以为彼此的饮食和身体行为行为改变。基于SDT（SDT-WL）或基于行为理论（BWL）的6个月治疗，将随机分为64对夫妇进行6个月的治疗。夫妻将在每周一次的会议上进行6个月，并将在0、6和12个月进行评估。我们预测，通过加强自主支持，SDT-WL将增加自主的自我调节和感知能力，并比标准行为治疗产生更大的体重减轻和维持。该研究的重点是夫妻而不是个人，理论上是基于自主性支持，并将其与其他类型的支持区分开来，并直接培训了这种支持行为的伴侣。如果成功，我们将寻求资金在更大的随访期间进行更大的试验中测试SDT方法。
