Informed by the person-environment fit theory, this preliminary study examined if a fit between a group member's treatment experience and their working therapy context (other group members' aggregated treatment experiences) were related to their level of motivation within a group treatment for healing from internalized weight stigma.
We examined the relationship between two types of within-member and between-member's group cohesion, working alliance, and motivation. Specifically, we utilized the Actor-Partner Interdependence Model to operationalize the impact of actor's within-member cohesion and alliance (personal changes over time) and between-member cohesion and alliance (individual differences) as well as partner's within-member cohesion and alliance (contextual changes over time) and between-member cohesion and alliance (contextual differences) on group members' motivation. This study utilized self-report data from 26 group members who participated in three online weight stigma psychotherapy groups.
For cohesion, results suggested that the relationship between partner within-member cohesion and motivation was larger for members who reported low cohesion across all the sessions compared to the other members of their group. Additionally, an individual group member who perceived a group session more cohesive than they did on average, reported increased motivation in that session, and this relationship was stronger for members who on average perceived their group less cohesive than other group members. Lastly, session-level alliance was more strongly associated with an individual member's motivation in that session when the other group members reported higher group alliance on average.
These findings underscore the significance of member-group fit in group therapy and the reciprocal impact of individual members and the group on each other's therapy outcomes.
基于人-环境匹配理论，本初步研究考察了在针对内化体重污名的群体治疗中，小组成员的治疗经历与其工作治疗环境（其他小组成员的综合治疗经历）之间的匹配度是否与他们在小组治疗中的动机水平相关。
我们考察了两种类型的成员内部和成员之间的群体凝聚力、工作联盟与动机之间的关系。具体而言，我们运用行动者-伙伴相互依赖模型来衡量行动者的成员内部凝聚力和联盟（随时间的个人变化）、成员之间的凝聚力和联盟（个体差异）以及伙伴的成员内部凝聚力和联盟（随时间的情境变化）和成员之间的凝聚力和联盟（情境差异）对小组成员动机的影响。本研究使用了来自26名参与三个在线体重污名心理治疗小组的小组成员的自我报告数据。
关于凝聚力，结果表明，与小组中的其他成员相比，在所有疗程中报告凝聚力较低的成员，其伙伴的成员内部凝聚力与动机之间的关系更大。此外，一名个体小组成员若认为某一小组疗程比其平均感受更具凝聚力，则该疗程中其动机有所增强，而且对于那些平均而言认为自己所在小组凝聚力低于其他小组成员的成员，这种关系更强。最后，当其他小组成员平均报告更高的小组联盟时，疗程层面的联盟与该疗程中个体成员的动机之间的关联更强。
这些发现强调了成员与小组匹配在团体治疗中的重要性，以及个体成员与小组对彼此治疗结果的相互影响。
