「個人與社會功能量表—照護者中文版本」之發展與驗證

Development and Validation of the Chinese Caregiver Version of the Personal and Social Performance Scale

目的：本研究之目的旨在從原本精神科臨床專業人員使用的個人與社會功能量表 (PSP)，延伸發展一份病人的照護者也可以使用的照護者版本 (caregiver version)，本量表將幫 助照護者針對精神分裂病人的個人與社會功能變化進行評估。方法：量表初稿經專家效度修 改後完成預試量表，量表結構分兩部分，第一部分為個人與社會功能量表，第二部份為基本 資料。以本院門診追蹤之200 個精神分裂症病人的主要照護者為預試對象，預試所得資料進 行項目分析、效度考驗及信度檢定。結果：因素分析結果各因素可解釋變異量在53.46% 到 73.42% 之間，信度分析得到總量表α 係數為0.91，再測信度為 0.89，評分者間信度為0.91， 為具有良好的效度與信度。結論：本研究發展之個人與社會功能量表－－照護者版本正式量 表，其內容計四個因素層面，分別為一般角色功能、人際與社交關係、自我照顧能力、干擾 與攻擊行為共20 題。

Objectives: To develop a caregiver version of the original Personal and Social Performance (PSP) Scale, a scale which is widely used by psychiatric clinical professionals to provide caregivers with a method for assessing personal and social functioning changes in patients with schizophrenia. Methods: The pre-test questionnaire, which was completed after modifying the initial draft in accordance with an expert validity review, is divided into the fi rst part containing the personal and social functioning scale, and the second part having basic information. The pre-test subjects consisted of 200 primary caregivers who were caring for clinic outpatients with schizophrenia. All of the obtained pre-test information was subjected to item analysis, validity testing, and reliability testing. Results: The factor analysis results for each factor revealed that the variances were between 53.46% and 73.42%, and that Cronbach’s α of the reliability test was 0.91. The test-retest reliability and inter-rater reliability of the newly developed scale were 0.89 and 0.91, respectively, showing that the validity and reliability of the scale were satisfactory. Conclusions: The caregiver version of the PSP in Chinese developed in this study contains 20 questions distributed among four domains, i.e., socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior.
