Study population: Patients diagnosed with uni-or bilateral symptomatic knee or hip OA from the Rheumatology Division of Physical Medicine and Rehabilitation Department, Marmara University Faculty of Medicine, with the age between 18-75 years were included.

Brief summary: In this paper, the adaptation of the Mini-OAKHQoL questionnaire in the Turkish population analyzing the feasibility, reliability, and validity of the questionnaire was documented.

Detailed description: Knee and hip osteoarthritis are common diseases that play an important role in health-related quality of life (HR-QoL). Assessing HR-QoL with a disease- and site-specific HR-QoL is more advantageous than generic scales. In that concept, to our knowledge, there is not any osteoarthritis- and lower limb-specific HR-QoL instrument to use in Turkey. Mini-OAKHQoL was derived from the OAKHQoL questionnaire, which was developed to assess the quality of life (QoL) in subjects with lower limb osteoarthritis. Its good psychometric properties have recently been shown and validation studies have been done in several populations. Mini-OAKHQoL's validation study has not been done before in Turkey. The aim is to investigate the validity and reliability of the Turkish version of the Mini-OAKHQoL. Patients diagnosed with knee or hip osteoarthritis were recruited. For cross-cultural adaptation, items of Mini-OAKHQoL were selected from the interrelated Turkish version of the OAKHQoL study in which the adaptation process had already done. Missing data, floor effect, and ceiling effect were calculated. Reliability analysis with internal consistency and test-retest reliability were discovered. Face, content, convergent, and divergent validities were applied.
