Patterns of illness behaviors and its correlates in patients with chronic nonorganic pain

Background: Illness behaviors if abnormal can have significant influence in presentations of chronic pain. The aim of the study was to derive the patterns of illness behaviors and its correlates in subjects with chronic nonorganic pain. Methods: Illness Behavior Questionnaire (IBQ) was administered to 301 adult individuals with chronic nonorganic pain. Factor analysis was performed on the IBQ, and relationships of the dimensions of illness behavior with clinical and demographic variables were computed. Results: Majority of the sample consisted of women (n = 208; 69%) with 43% from rural background and 58% from below poverty line status. Principal axis factoring resulted in four factors, namely health concerns, affective inhibition (AI), bodily distress, and affective distress with psychosocial problems. The three factors excluding AI had significant intercorrelation among them. There was significant difference in mean scores of factors, bodily distress and affective distress in patients from urban and rural background. Conclusions: Illness behaviors in chronic nonorganic pain can be understood as three interrelated factors-health concerns, affective distress with psychosocial problems, and bodily distress. AI might be an independent factor for presentation of chronic nonorganic pain.
