Homestay hosts expend considerable social efforts to ensure that guests like their host and homestay. Despite the process of generating affinity for the hosts is central to social exchanges in homestays, there still lacks a valid scale to measure the affinity-seeking strategies of hosts. To address this gap, this study uses multi-step mixed methods to develop a measurement scale for the affinity-seeking strategies of homestay hosts. A formative hierarchical component model of the affinity-seeking strategies of hosts is proposed in this study. Four first-order formative indicators are validated, namely, presenting personal attractiveness, showing friendly attitudes, facilitating enjoyment and social contact, and providing service and help. Furthermore, the stimulus–organism–response (S–O–R) model is used to validate the second-order formative constructs. The results show that the affinity-seeking strategies of homestay hosts positively affect guests' emotional value and intention to cooperate with hosts. The findings contribute to a measurable definition of hosts’ affinity in the context of homestays.

寄宿家庭的主人付出了相当大的社会努力来确保客人喜欢他们的主人和寄宿家庭。尽管产生对主人的亲和力的过程是寄宿家庭社会交流的核心，但仍然缺乏有效的量表来衡量主人的亲和力寻求策略。为了弥补这一差距，本研究使用多步混合方法来制定寄宿家庭寻求亲和力策略的测量量表。本研究提出了宿主亲缘关系寻求策略的形成层次组件模型。验证了四个一阶形成指标，即展现个人吸引力、展现友好态度、促进享受和社交接触以及提供服务和帮助。此外，刺激-有机体-反应 (S-O-R) 模型用于验证二阶形成性结构。结果表明，寄宿家庭主人的亲和力寻求策略对客人的情感价值和与主人合作的意愿有积极影响。研究结果有助于对寄宿家庭中主人的亲和力进行可衡量的定义。
