Background.The Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire is a tool designed for self assessment of forearm pain and disability in patients with lateral elbow tendinopathy (LET). However, an Italian version of this questionnaire is not yet available.Objective.To translate and cross-culturally adapt the PRTEE questionnaire into Italian, and to evaluate its measurement properties.Design. longitudinal observational measurement study. METHODS:The PRTEE questionnaire was cross-culturally adapted to Italian according to established guidelines. Ninety-five (41 women, 54 men) patients with unilateral, imaging-confirmed, chronic LET were selected consecutively to assess the measurement proprieties of the PRTEE Questionnaire. Internal consistency, test-retest reliability, construct validity, and responsiveness were estimated. RESULTS: The Italian version of the PRTEE displayed a high degree of internal consistency, with a Cronbach's alpha of 0.95. The test-retest reliability was high for both short-term and medium-term, with an ICC((2,1)) of 0.95 and 0.93, respectively. The PRTEE exhibited a strong correlation (r = .77-.91; P <.0001) with the DASH at the baseline, and a moderate correlation (r = .58-.74; P < .0001) at discharge. The responsiveness was higher for the PRTEE than for the DASH.Limitations.A methodological limitation of our study is that due to a small sample size we did not perform factor analysis to assess convergent validity. CONCLUSIONS:The Italian version of the PRTEE Questionnaire is internally consistent, demonstrates expected correlations with other measures, and is more responsive than the DASH in Italian patients with chronic LET.
