Arabic Version Of Henry Ford Hospital Headache Disability Inventory Questionnaire : Cross Cultural Adaptation, Validity, And Reliability

ARABIC VERSION OF HENRY FORD HOSPITAL HEADACHE DISABILITY INVENTORY QUESTIONNAIRE: CROSS-CULTURAL ADAPTATION, VALIDITY, AND RELIABILITY

This questionnaire will be developed to assess the impact of headache on functional and emotional aspects of daily life. The Alpha version of HDI (alpha-HDI) included 40 items, but the newest Beta version (beta-HDI) contains 25 items. The Beta version of HDI, developed by Jacobson (1994) in English, is a generic headache disability questionnaire widely administered in the related research studies.

This questionnaire measures the effect of different medical and rehabilitation treatments on the physical and emotional disabilities in patients with different types of headaches. This generic headache questionnaire is not specific to any headache type. Therefore, HDI will be applied to follow the general consequences of different headache types and to compare different aspects of disability for a variety of headaches. Based on the literature, the original HDI has strong internal consistency/reliability and construct validity. The results of test-retest showed that HDI has an acceptable level of reliability considering the total questionnaire and its subscale scores.

The validity and reliability of the non-English versions of HDI, such as Spanish, have been previously investigated and confirmed. The Arabic researchers and practitioners need valid and reliable tools to measure the emotional and functional states of patients with different headache disorders.

So, This study will be carried out to translate and culturally adapt the HDI questionnaire for administration among the Egyptian patients with headaches. Moreover, This study will assess the validity and reliability of the developed Arabic version of this questionnaire. Creation of questionnaires in different languages must pass through many steps. Questionnaires must be translated, then culturally adapted to the environment in which they will be used.
