The main purpose of this study was to estimate the minimal detectable change (MDC) on the Lawton Instrumental Activities of Daily Living (LIADL) scale in community-dwelling patients with schizophrenia. Fifty-seven patients completed the LIADL assessment twice, about 14 days apart. Two scoring methods (dichotomous and polytomous) were used to record the patients' performance on the LIADL scale. The MDCs of the LIADL scale were 1.5 (dichotomous) and 4.4 (polytomous) points. The MDC percentages were 22.0% (dichotomous) and 22.5% (polytomous), both of which are within acceptable measurement errors. The test-retest reliabilities of the LIADL scale were both acceptable with two different scoring methods (dichotomous = .75; polytomous = .76). Users can choose the scoring method according to their individual needs.
本研究的主要目的是评估社区精神分裂症患者在洛顿日常生活能力量表（LIADL）上的最小可检测变化（MDC）。57名患者完成了两次LIADL评估，间隔约14天。采用两种评分方法（二分法和多分法）记录患者在LIADL量表上的表现。LIADL量表的MDC分别为1.5分（二分法）和4.4分（多分法）。MDC百分比分别为22.0%（二分法）和22.5%（多分法），均在可接受的测量误差范围内。LIADL量表在两种不同评分方法下的重测信度均可接受（二分法=.75；多分法=.76）。使用者可根据个人需求选择评分方法。
