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 has not been available. Objective The aims of this study were: (1)
to translate and cross-culturally adapt the PRTEE questionnaire into Italian and
(2) to evaluate its measurement properties. Design This was a longitudinal,
observational measurement study. METHODS: /b> The PRTEE questionnaire was
cross-culturally adapted to Italian according to established guidelines.
Ninety-five individuals (41 women, 54 men) with unilateral, imaging-confirmed,
chronic LET were selected consecutively to assess the measurement properties of
the PRTEE questionnaire. Internal consistency, test-retest reliability, construct
validity, and responsiveness were estimated. RESULTS: /b> The Italian version of
the PRTEE displayed a high degree of internal consistency, with a Cronbach alpha
of .95. The test-retest reliability was high for both short-term and medium-term,
with intraclass correlation coefficients (2,1) of .95 and .93, respectively. The
PRTEE exhibited a strong correlation (r=.77-.91, P<.0001) with the Disabilities
of the Arm, Shoulder and Hand (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 the study is that
due to the small sample size, a factor analysis was not performed to assess
convergent validity. CONCLUSIONS: /b> 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.
