TI  - The Penn shoulder score: reliability and validity.
PG  - 138-51
AB  - STUDY DESIGN: Psychometric evaluation of a cross-sectional survey. OBJECTIVES: 
      The purpose of this study was to examine the psychometric properties of 
      reliability and validity of the Penn Shoulder Score (PSS). BACKGROUND: Shoulder 
      outcome measures are used to assess patient self-report levels of pain, 
      satisfaction, and function. The PSS is a 100-point shoulder-specific self-report 
      questionnaire consisting of 3 subscales of pain, satisfaction, and function. This 
      scale has been utilized in the literature. However, the measurement properties of 
      reliability and validity, including responsiveness, of the PSS subscales and 
      overall scale need to be established. METHODS AND MEASURES: Patients (n = 40) 
      with shoulder disorders undergoing a course of outpatient physical therapy 
      completed the PSS at initial visit and again within 72 hours to assess 
      test-retest reliability. The Constant Shoulder Score (CSS) and the American 
      Shoulder and Elbow Surgeons Shoulder Score (ASES) were also completed at the 
      initial visit and compared to the PSS to assess convergent construct validity. A 
      separate cohort of patients (n = 109) completed the PSS at initial visit and 4 
      weeks later. These scores were used to assess internal consistency and 
      responsiveness. RESULTS: Reliability analysis revealed a test-retest ICC2,1 of 
      0.94 (95% CI, 0.89-0.97). Internal consistency analysis revealed a Cronbach alpha 
      of 0.93. The standard error of measurement (SEM) was +/- 8.5 scale points (based 
      on a 90% CI) and the minimal detectable change (MDC) was +/- 12.1 scale points 
      (based on a 90% CI). The minimal clinically important difference (MCID) for 
      improvement was 11.4 points. Pearson product moment correlation coefficients 
      between the PSS and the CSS and ASES were 0.85 and 0.87, respectively. 
      Responsiveness analysis revealed an effect size of 1.01 and a standardized 
      response mean of 1.27. CONCLUSIONS: This study has demonstrated that the PSS is a 
      reliable and valid measure for reporting outcome of patients with various 
      shoulder disorders.
