Fostering a strong professional identity (PI) enhances career fulfillment. In China, therapy education is undergoing development, integrating both Western and traditional health concepts, causing inconsistent PI among therapy students. To date, no validated tools exist to measure and monitor PI of Chinese therapy students. This study aimed to translate and validate the 9-item MacLeod Clark Professional Identity Scale (MCPIS-9) for this purpose.
This study involved translation and cultural adaptation of the MCPIS-9, followed by a rigorous assessment of its model fit and psychometric properties using data collected via an online questionnaire.
A forward- and backward- translation process was conducted. Content validity was evaluated using item-level content validity index (I-CVI) and scale level content validity index average method (S-CVI/Ave). Therapy students across all grades at undergraduate and postgraduate levels in China were eligible. Exploratory factor analysis (EFA) examined the underlying factor structure. Model fit was evaluated through confirmatory factor analysis (CFA) using the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Standardized Root Mean Square Residual (SRMR) and Root Mean Square of Error of Approximation (RMSEA). Convergent validity was assessed through Pearson's correlations coefficient (r) with the Professional Identity Scale for Health Students and Professionals (PISHSP). Internal consistency was examined using Cronbach's Alpha (Cα) and McDonald's Omega (ω).
A total of 1054 students participated. Content validity was excellent (I-CVI = 0.86-1.0, S-CVI/Ave = 0.98). EFA indicated a two-factor structure with acceptable model fit (CFI = 0.978; TLI = 0.968; SRMR = 0.033; RMSEA = 0.063). Reliability was strong (Cα = 0.835; ω = 0.817). Convergent validity demonstrated a strong correlation (r = 0.75) with the PISHSP.
The Chinese MCPIS-9 is a reliable and valid tool for assessing PI among therapy students. Future research could focus on refining item 4 of this tool, potentially through further exploration of therapy students' perceptions of PI within the unique context of the Chinese healthcare system.
培养强烈的职业认同感（PI）可提升职业成就感。在中国，治疗学教育正在发展，融合了西方和传统健康观念，这导致治疗学专业学生的职业认同感不一致。迄今为止，尚无经过验证的工具来测量和监测中国治疗学专业学生的职业认同感。本研究旨在为此目的翻译并验证9项麦克劳德·克拉克职业认同感量表（MCPIS - 9）。
本研究涉及MCPIS - 9的翻译和文化调适，随后使用通过在线问卷收集的数据对其模型拟合度和心理测量特性进行严格评估。
进行了正向和反向翻译过程。使用项目级内容效度指数（I - CVI）和量表级内容效度指数平均法（S - CVI/Ave）评估内容效度。中国本科和研究生各年级的治疗学专业学生均符合条件。探索性因素分析（EFA）检验潜在因素结构。使用比较拟合指数（CFI）、塔克 - 刘易斯指数（TLI）、标准化根均方残差（SRMR）和近似误差均方根（RMSEA）通过验证性因素分析（CFA）评估模型拟合度。通过与健康专业学生和专业人员职业认同感量表（PISHSP）的皮尔逊相关系数（r）评估收敛效度。使用克朗巴哈α系数（Cα）和麦克唐纳ω系数（ω）检验内部一致性。
共有1054名学生参与。内容效度良好（I - CVI = 0.86 - 1.0，S - CVI/Ave = 0.98）。探索性因素分析表明为两因素结构，模型拟合度可接受（CFI = 0.978；TLI = 0.968；SRMR = 0.033；RMSEA = 0.063）。信度较高（Cα = 率0.835；ω = 0.817）。收敛效度显示与PISHSP有强相关性（r = 0.75）。
中文版MCPIS - 9是评估治疗学专业学生职业认同感的可靠且有效的工具。未来研究可聚焦于完善该工具的第4项，可能通过在中国医疗体系独特背景下进一步探索治疗学专业学生对职业认同感的认知来实现。
