Validity and reliability of the Dutch version of the Copenhagen Hip And Groin Outcome Score (HAGOS-NL) in patients with hip pathology

This Dutch translation of the Perth Alexithymia Questionnaire (PAQ) was translated from the original English version. An initial translation from English to Dutch was conducted and refined by the authorship team. These Dutch items were then back-translated into English by a NAATI approved translator. Minor refinements to some of the Dutch items were made by the authorship team on the basis of this back-translation, resulting in the final Dutch version of the PAQ presented in this document. Our team is currently conducting a psychometric study on this Dutch PAQ to examine its validity and reliability. Deze Nederlandstalige vertaling van de Perth Alexithymia Questionnaire (PAQ) is vertaald vanuit de oorspronkelijke Engelse versie. Een eerste vertaling van het Engels naar het Nederlands werd uitgevoerd en verfijnd door het auteursteam. Deze Nederlandstalige items werden vervolgens terugvertaald naar het Engels door een door NAATI erkende vertaler. Op basis van deze hervertaling zijn door het auteursteam kleine verfijningen aangebracht in enkele Nederlandstalige items, wat heeft geleid tot de definitieve Nederlandstalige versie van de PAQ die in dit document wordt gepresenteerd. Ons team voert momenteel een psychometrische studie uit op deze Nederlandstalige PAQ om de validiteit en betrouwbaarheid te onderzoeken.

ABSTRACT Due to a lack of a validated Dutch version of the Hip Outcome Score (HOS) considering functional outcome after hip arthroscopy for femoroacetabular impingement syndrome, we validated the Dutch version of the HOS (HOS-NL) in patients with femoroacetabular impingement syndrome for reliability, internal consistency, construct- and content validity. Furthermore, the smallest detectable change (SDC) and minimal clinically important difference (MCID) were determined. All consecutive patients scheduled for an arthroscopic procedure for FAIS were selected. Five questionnaires covering groin and hip pain were filled in at three moments in time (two pre-operatively with a maximum two-week interval and 6 months postoperatively). Main endpoints were reliability (test re-test, SDC), internal consistency (Cronbach alpha), construct validity (construct validity was considered sufficient if a least 75% of a-priori made hypotheses were confirmed), content validity (floor and ceiling effects) and responsiveness (MCID). The intraclass correlation coefficient (ICC) was 0.86 for the HOS ADL-NL and 0.81 for the HOS Sports-NL. SDC for the HOS ADL-NL was 21 and for the HOS Sports-NL 29 Cronbach alpha score was 0.882 for HOS ADL-NL and 0.792 for HOS Sports-NL. Construct validity was considered sufficient since 91% of the hypotheses were confirmed. No floor effects were determined. A small ceiling effect was determined for the HOS AD-NL postoperatively. The MCID for HOS ADL-NL and HOS Sports-NL were 14 and 11.0, respectively. The HOS-NL is a reliable and valid patient reported outcome measure for measuring physical function and outcome in active and young patients with femoroacetabular impingement syndrome.
