The aim of the study was the development and evaluation of the psychometric properties of a self-assessment questionnaire for resource-orientated coping with cancer (Patient Competence Questionnaire, PCQ). In 420 patients and members of cancer support-groups item selection and evaluation of item properties, reliability (Cronbach's Alpha), validity (convergent and divergent) and factorial structure were performed in two studies. The final version of the PCQ (18 items) demonstrated a Cronbach's Alpha between 0.71 and 0.91 for five subscales identified with exploratory factor analysis (religious/spiritual coping, coping competence, healthy lifestyle, information seeking, adaptability) and 0.85 for the total score. The PCQ shows a high convergent validity (r = 0.46) with the Freiburg Questionnaire on Coping with Illness (FKV) and significant correlations with depression (r = -0.23), posttraumatic growth (r = 0.65) and religiosity (r = 0.59). First analyses underline that the PCQ can be regarded as a valid and reliable instrument for assessing patients' resources in dealing with cancer.
本研究的目的是开发和评估一份用于以资源为导向应对癌症的自我评估问卷（患者能力问卷，PCQ）的心理测量特性。在两项研究中，对420名癌症患者及癌症支持小组的成员进行了项目选择、项目特性评估、信度（克朗巴哈系数）、效度（收敛效度和区分效度）以及因子结构分析。PCQ的最终版本（18个项目）在通过探索性因子分析确定的五个分量表（宗教/精神应对、应对能力、健康生活方式、信息寻求、适应能力）上的克朗巴哈系数在0.71至0.91之间，总分的克朗巴哈系数为0.85。PCQ与《弗莱堡疾病应对问卷》（FKV）具有较高的收敛效度（r = 0.46），并与抑郁（r = -0.23）、创伤后成长（r = 0.65）和宗教信仰（r = 0.59）存在显著相关性。初步分析强调，PCQ可被视为评估患者应对癌症资源的有效且可靠的工具。
