中文版工作復健問卷於思覺失調症患者之信效度研究

研究背景與目的：鑒於國內沒有以ICF為基礎且心理計量特性良好，並能精確評估思覺失調症患者職業復健功能的問卷，故本研究之目的為：檢驗中文版工作復健問卷應用於思覺失調症患者的信度及效度，評估其職業復健能力，進而協助思覺失調症者重返工作。方法：本研究為橫斷性研究，在北部某醫院體系之三家日間型精神復健機構以及門診招募75位個案，以問卷評估調查的方式進行資料收集。以「中文版工作復健問卷」、「慢性精神病患者工作行為量表」及「工作自我效能量表」評估思覺失調症者的職業復健功能，用以檢驗中文版工作復健問卷之信度(再測組內信度、內部一致性)及效度(區辨效度、同時效標關聯效度)。結果：「中文版工作復健問卷」應用於思覺失調症者上顯示全量表具有良好之內部一致性(Cronbach’s Alpha值.95)及良好的再測組內信度(ICC組內相關係數為.82)。「中文版工作復健問卷」與「工作自我效能量表」呈現顯著高度相關(p＜.001)，兩量表具有同時效標關聯效度。「中文版工作復健問卷」與「慢性精神病患者工作行為量表」則呈現無相關。結論：「中文版工作復健問卷」是一個具有信度、效度，以ICF為基礎的問卷，且易於被精神復健及職業重建的相關專業評估個案的職業復健功能。由台灣思覺失調症個案的主觀觀點反應出的職業復健能力，讓職業重建相關專業人員更瞭解個案整體的功能，以協助思覺失調症者在適合的時機點上重返工作。

Purpose：There is no questionnaire based on International Classification of Functioning, Disability and Health (ICF) with excellent psychometric characteristics to evaluate work function of people with schizophrenia in Taiwan currently. The purpose of this study is to establish the reliabilities and validities of the Chinese Version of the Work Rehabilitation Questionnaire (WORQ) for people with schizophrenia, in order to evaluate their work function. Methods：This study is a cross-sectional study. We conducted a questionnaire-based survey and interviewed 75 subjects with schizophrenia who were recruited from three psychiatric rehabilitation centers and outpatient department of a psychiatric hospital in northern Taiwan. We used “Chinese Version of the WORQ”, “Work-Related Self-Efficacy Scale” and “Work Behavior Inventory” as means to evaluate the work function of people with schizophrenia, in order to test psychometric properties including internal consistency, test-retest reliability, concurrent validity and discriminant validity of the Chinese Version of the WORQ . Results： The psychometric evaluation of the Chinese Version of the WORQ indicated a high test–retest reliability (ICC 0.82) (n = 25) and a good internal consistency (Cronbachs Alpha 0.95) (n = 75). The Chinese Version of the WORQ demonstrated a high correlation with the Chinese Version of the Work-Related Self-Efficacy Scale (Pearson’s r -0.60) and no correlation (Pearson’s r -0.07) with the Chinese Work Behavior Inventory. Conclusion: The Chinese Version of the WORQ appears to be a reliable, valid and ICF-based questionnaire to evaluate the work function, and is easy to be administered by psychiatric rehabilitation or vocational professionals. By reflecting the subjective perspectives on the ability in vocational rehabilitation, it will give vocational rehabilitation professionals a better understanding about work function of people with schizophrenia and assist them to return to work.
