疾病认知问卷（ICQ; Evers等人，J Consult Clin Psychol，69：1026-1036，2001）评估了三种认知评估慢性疾病的压力和厌恶特征的方法：无助、接受和感知益处。本研究的目的是评估ICQ在慢性疼痛和慢性疲劳患者中的结构效度。进行了解释性因素分析，以评估假设的三因素结构，包括因素“无助”，“接受”和“感知的好处。“我们进行了多组分析，以研究两组的因素结构的稳定性，结果证实两个样本的三因素结构。因子结构在慢性疼痛和慢性疲劳患者中是不变的，由于三因子结构在两组中都提供了良好的拟合，我们证实了子量表评分在研究和临床实践中的有用性。
The Illness Cognition Questionnaire (ICQ; Evers et al., J Consult Clin Psychol, 69:1026-1036, 2001) assesses three ways of cognitively evaluating the stressful and aversive character of a chronic illness: helplessness, acceptance, and perceived benefits.The purpose of this study was to evaluate the construct validity of the ICQ in individuals with chronic pain and patients with chronic fatigue.The ICQ was administered to 821 individuals with chronic pain and 295 patients with chronic fatigue. Confirmatory factor analyses were performed to assess the hypothesized three-factor structure, containing the factors "helplessness," "acceptance," and "perceived benefits." A multigroup analysis was performed to investigate the stability of the factor structure in both groups.Results confirmed the three-factor structure in the two samples. The factor structure was invariant across individuals with chronic pain and chronic fatigue.As the three-factor structure provided a good fit in both groups, we confirm the usefulness of the subscale scores in research and clinical practice.
