The development and psychometric assessment of the Turkish version of the Nottingham Health Profile.

The Nottingham Health Profile (NHP) is a widely used measure of perceived health status. The aim of the present study was to adapt the NHP for use in Turkey and to test its psychometric properties. Following translation and testing for its face and content validity, 50 patients with osteoarthritis were interviewed on two occasions. Each interview included administration of the NHP and the Stanford Health Assessment Questionnaire (HAQ), a measure of functional disability. Test-retest reliability of the new version was satisfactory and comparable with other available language versions. As predicted, high correlations were found between the HAQ and the physical mobility, pain and energy level sections of the NHP and low correlations between the HAQ and emotional reactions, social isolation and sleep, confirming the construct validity of the NHP. It is concluded that the adaptation of the NHP into Turkish was successful but that additional studies are required to assess its suitability for use with other patient populations and its equivalence to other language versions of the measure.
