This study aims to assess the factor structure of the Turkish Revised Illness Perception Questionnaire (IPQ-R) in patients with rheumatoid arthritis (RA) and the relationship of illness perceptions with disease activity and psychological well-being.
One hundred and fifty RA patients (8 males, 142 females; mean age 51.1±12.7 years; range 21 to 81 years) were included in the study. Confirmatory factor analysis was used to test the factor structure of the IPQ-R. Pain was assessed by visual analog scale, disease activity by Disease Activity Score 28, depression by Beck Depression Inventory, global life satisfaction by the Satisfaction with Life Scale, and illness perception by the IPQ-R.
Three items (items 12, 18, 19) were deleted because of poor factor loadings. The modified 35-item model showed good reliability and discriminant validity. Beck Depression Inventory scores were correlated with identity, consequences, and emotional representations subscales positively (p<0.001); and with illness coherence subscale negatively (p<0.05). There were positive correlations between Satisfaction with Life Scale scores, and treatment control and illness coherence subscales (p<0.05). Satisfaction with Life Scale scores were negatively correlated with identity, emotional representation, and timeline acute/chronic subscales (p<0.05), and consequences subscale (p<0.001). Disease Activity Score 28 was not correlated with IPQ-R domains (p>0.05).
The Turkish IPQ-R appears to be a useful clinical assessment tool to evaluate RA-related illness perceptions. RA healthcare should include psychological intervention to strengthen patients' beliefs about their RA regardless of disease activity.
本研究旨在评估土耳其修订版疾病认知问卷（IPQ-R）在类风湿关节炎（RA）患者中的因子结构，以及疾病认知与疾病活动度和心理健康之间的关系。
本研究纳入了150例RA患者（8例男性，142例女性；平均年龄51.1±12.7岁；年龄范围21至81岁）。采用验证性因子分析来检验IPQ-R的因子结构。通过视觉模拟量表评估疼痛，通过疾病活动度评分28评估疾病活动度，通过贝克抑郁量表评估抑郁，通过生活满意度量表评估总体生活满意度，通过IPQ-R评估疾病认知。
由于因子载荷不佳，删除了3个条目（条目12、18、19）。修改后的35条目模型显示出良好的信度和区分效度。贝克抑郁量表得分与身份认同、后果和情感表征子量表呈正相关（p<0.001）；与疾病连贯性子量表呈负相关（p<0.05）。生活满意度量表得分与治疗控制和疾病连贯性子量表之间存在正相关（p<0.05）。生活满意度量表得分与身份认同、情感表征和时间线急性/慢性子量表呈负相关（p<0.05），与后果子量表呈负相关（p<0.
