Translation of the instrumental activities of daily living (IADL) was carried out and its psychometric properties were assessed in a Greek sample of patients with advanced cancer. The scale was translated with the forward-backward procedure into the Greek language. It was initially administered to 136 advanced cancer patients. To assess reliability, it was administered to 45 patients 3 days later. To assess the effect of treatment, 75 patients were studied. The patients also completed the Eastern Cooperative Oncology Group (ECOG) performance status and the linear analogue scale assessment (LASA) quality of life (QoL) scale. Confirmatory factor analysis of the IADL was carried out. Reliability was assessed in terms of internal consistency (Cronbach's α) and test-retest correlation (Pearson and ICC) of the IADL scale. Construct validity was assessed through correlation of IADL with ECOG and LASA QoL scores. Confirmatory factor analysis yielded a single-factor model. The homogeneity of the instrument proved to be satisfactory (α was 0.88 for men and 0.83 for women). Test-retest reliability was also satisfactory (P<0.0005). High correlation with ECOG (men, r=-0.87; women, r=-0.85) and LASA QoL (men, r=0.55; women, r=0.53) was observed. The Greek version of the IADL in cancer patients treated in a palliative care unit is a reliable and valid clinical instrument.
对日常生活工具性活动量表（IADL）进行了翻译，并在希腊晚期癌症患者样本中评估了其心理测量特性。该量表采用前后翻译程序翻译成希腊语。最初对136例晚期癌症患者进行了施测。为评估信度，3天后对45例患者再次施测。为评估治疗效果，对75例患者进行了研究。患者还完成了东部肿瘤协作组（ECOG）体能状态量表和线性模拟自评量表（LASA）生活质量（QoL）量表。对IADL进行了验证性因素分析。通过IADL量表的内部一致性（克朗巴赫α系数）和重测相关性（皮尔逊相关系数和组内相关系数ICC）评估信度。通过IADL与ECOG及LASA QoL评分的相关性评估结构效度。验证性因素分析得出单因素模型。该工具的同质性被证明是令人满意的（男性α系数为0.88，女性为0.83）。重测信度也令人满意（P<0.0005）。观察到与ECOG（男性，r=-0.87；女性，r=-0.85）和LASA QoL（男性，r=0.55；女性，r=0.53）高度相关。在姑息治疗病房接受治疗的癌症患者中，IADL的希腊语版本是一种可靠且有效的临床工具。
