Purpose: This study aims to develop and validate a Korean version of Illness Perception Questionnaire that measures patients` cognitive and emotional representations about their symptoms and diseases. The scale is expected to help patients and clinical staffs to have better communication by enhancing understandings of the patients` cognitive representations to their illnesses.
Methods: The authors translated the Illness Perception Questionnaire-Revised (IPQ-R) into Korean and investigated the validity and reliability of the Korean Illness Perception Questionnaire (K-IPQ) on patients with three different illness types: stroke, heart disease, and hypertension. The participants completed the K-IPQ, Fatigue Severity Scale, RAND SF-36, and several demographics-related questions.
Results: A Confirmatory factor analysis revealed that the K-IPQ had the same factor structure with the IPQ-R except for five items. Considering cultural and linguistic characteristics in Korean, the authors suggested the final version of the K-IPQ that consists of a total of 12 sub-constructs with33 questions. Discriminant validity tests showed that the cognitive representation subscale of the K-IPQ was distinctive from the scales for patients`emotional status (e.g., PANAS). A predictive validity test revealed that six sub-constructs of the K-IPQ (identity, personal control, treatment control, consequences, timeline-acute/chronic, timeline-cyclical, and illness coherence)significantly predicted health adaptation (general health, fatigue, and emotional distress).
Conclusions: The findings indicate that the K-IPQ is avalid and reliable scale for measuring Korean patients` illness perception. Future research is required to investigate the underlying psychological processes in the relationships between the sub-constructs of the K-IPQ and illness perception in different illness groups.ove nurse`s job engagement.
