Evidence from the literature and the current study suggests that disease-specific measures may be more sensitive to variations in the health-related quality of life of adolescents with migraine than general measures. The Migraine Specific Quality of Life Questionnaire, Adolescent form (MSQ-A) and the Headache Disability Inventory, Adolescent form (HDI-A) were designed to specifically assess direct and indirect functional impairment due to migraines, and migraine-related affective distress. There have been only limited attempts to evaluate the psychometric properties of MSQ-A and HDI-A and the current study aimed to examine the factor structure, validity and reliability of these instruments. 97 adolescents (age 11-17) with episodic migraine were recruited to participate in this study. Upon recruitment participants completed MSQ-A and HDI-A and additional validity measures. Participants then recorded their migraine symptoms in an electronic daily headache diary over a four week period. At the end of the four week period, participants were invited to visit the test setting again, submit the electronic diary and complete follow-up MSQ-A and HDI-A. Confirmatory factor analysis found the proposed three factor model for MSQ-A yielded only marginally good fit to the data. Modification indices suggested that the fit of the three factor model can be improved by the addition of six residual correlations between errors of items within the same subscale. The modified model was good fit to the data. However, high inter-correlatedness between the three subscales of MSQ-A raised concerns about their discriminant validity. The internal consistency of MSQ-A was adequate at both baseline and follow-up (a = .72-.94), but item-subscale correlations suggested that multiple MSQ-A items relate equally to two or more of its subscales. Similarly, while MSQ-A demonstrated significant relationships in the expected directions with criterion measures in this study, correlations between its subscales with each criterion measures were of similar magnitude, raising questions about the utility of the MSQ-A subscales as separate constructs. Exploratory maximum likelihood factor analysis of HDI-A did not provide support for any meaningful factor structure of the instrument. Because no meaningful factors were identified, only the reliability and validity of HDI-A total score were explored. The internal consistency of HDI-A was adequate at both baseline and follow-up (a = .89-.92). While significant relationships were found between HDI-A and all validity measures in this study, examination of these relationships provided no evidence that HDI-A is sensitive to migraine-related impairment. Moreover, since as a single factor measure HDI-A was not a good fit to the data, the use of its total score may be problematic.
