四肢機能障害を有する脳卒中生存者の社会的参加の潜在的プロファイル分析：混合研究法によるアプローチ

This study aimed to identify profiles of social participation among stroke survivors with limb dysfunction and explore the factors influencing these profiles.

A convergent mixed-methods design.

The quantitative phase involved 499 participants recruited from 5 neurorehabilitation centres in Shanghai between December 2023 and June 2025. Participants completed measures including the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P), the Connor-Davidson Resilience Scale (CD-RISC-10), and the Modified Rankin Scale (mRS). Qualitative semi-structured interviews were performed with 16 participants to explore lived experiences of social participation.

Latent profile analysis revealed 4 distinct social participation profiles: "Active Integration", "Contented Conservatism", "Cautious Conservatism", and "Alienated Disengagement". A multivariate analysis identified age, resilience, and physical function as significant predictors of profile membership. Qualitative findings uncovered 2 core emotional experiences (a sense of loss vs a sense of rebuilding) and 3 behavioural patterns (activist, conservative, alienated), which effectively explained the quantitative profiles' characteristics and their underlying mechanisms. The integration of data provided a nuanced person-centred framework depicting the heterogeneity in post-stroke social participation.

Social participation among stroke survivors is heterogeneous and can be classified into 4 distinct profiles shaped by the interplay of physical function, resilience, and sociodemographic factors. The findings underscore the necessity of implementing profile-specific, stepped-care interventions for effectively enhancing post-stroke social participation.
