Development and Validation of Scale of Psychosocial Issues for Patients With Migraine.

The current study was intended to develop and explore psychosocial issues of migraine patients in Pakistani culture context. In first phase of scale development, 16 participants were interviewed individually with inclusion criteria of diagnosed migraine history, aged 18-35 years (M = 23.84, SD = 3.64) generating an item pool of 44 psychosocial issues experienced by them. After 13 experts' validation, 36 items were finalized and tried out on 10 participants. To determine psychometric properties, Scale of Psychosocial Issues was presented along with demographic sheet to 160 migraine patients (41 men and 119 women). Exploratory factor analysis of Psychosocial Issues Scale clustered total of 34 items into three factors named as Functional Impairment, Mental Exhaustion, and Somatic Problems. Scale of Psychosocial Issues was found to have high internal consistency .92, test-retest reliability .80, split-half reliability .86 and .85, and acceptable convergent validity. Moreover, results were discussed in context of factor structure of Psychosocial Issues Scale, demographics and risk factors as predictors of newly developed scale in cultural context.
