Turkish language translation, validity and reliability of the Work-Health-Personal Life Perceptions Scale in arthritis

BackgroundThe Work-Health-Personal Life Perceptions Scale may help in the understanding of the biopsychosocial impact of rheumatic conditions on work participation, and assist in the planning and evaluation of work interventions.ObjectiveThe aim of this study was to translate to Turkish language and determine reliability and validity of the Work-Health-Personal Life Perceptions Scale (WHPLPS) for arthritis in Turkish society.MethodsThe study included100 arthritis patients aged 18-65 years. The WHPLP-S was used to evaluate work, health, personal life balance and conflict related to chronic physical illness. The Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) and Arthritis Impact Measurement Scale (AIMS-2) were used to examine the scale validity. Cronbach's alpha, intraclass correlation coefficients (ICCs) were evaluated for internal consistency and test-retest reliability, respectively.ResultsThe Cronbach's α value for the scale scores showed excellent internal consistency (Cronbach α: 0.931, 0.928, 0.828 for all sub-scoring). According to the test-retest reliability, it was found to be highly reliable (ICC: 0.870, 0.865, 0.770).ConclusionThe results of this study demonstrated that the Turkish translation of WHPLPS is a valid and reliable tool. This is the first study to have adapted the original English version of the WHPLPS to a different language and reliability studies. This scale should be used by clinicians to assess work perception in patients with arthritis.
