Psychometric properties of three different scales for subjective evaluation of shoulder pain and dysfunction in Italian patients after shoulder surgery for anterior instability

Measures of Adult Shoulder Function

“…One study reported ICCs of 1 (95% CI 1‐1) and 0.97 (95% CI 0.91‐0.99) measured in patients with instability and rotator cuff disease, respectively (172). In a study of patients attending a surgical clinic, the ICC = 0.99 (31); in studies of Dutch patients with shoulder complaints, the ICC = 0.86 (175) and 0.92 (166); in Italian patients after surgery for instability, the ICC = 0.97 (170); and in patients with various shoulder problems in Iran, the ICC = 0.94 (95% CI 0.86‐0.97 (169) and in Spain, the ICC = 0.912 (168).…”

“…The SST has been translated, adapted, and validated in Dutch (166), Brazilian Portuguese (167), Spanish (168), Persian (169), Italian (170), and Lithuanian (171).…”

“…Estimates of the internal consistency of the SST have been reported across various patient populations, including patients with various shoulder complaints: (Cronbach’s α = 0.85) (29), Brazilian patients with various shoulder complaints: (Cronbach’s α = 0.82, 95% CI 0.76‐0.86) (167), Dutch patients with shoulder problems attending an orthopedic clinic (Cronbach’s α = 0.78; removing items from the questionnaire did not result in higher Cronbach’s α ) (166), Italian patients after surgery for anterior instability (Cronbach’s α = 0.87) (170), and Iranian patients with a variety of shoulder disorders (Cronbach’s α = 0.73) (169).…”

“…Pearson’s or Spearman’s coefficients for correlation of the STT with other general and shoulder‐specific outcome measures (and the population they were measured in) are as follows: SPADI: ICC = 0.74 and 0.80 (29,36) in various shoulder problems; and ICC = 0.68, pain subscale ICC = 0.63, and function subscale ICC = 0.72 Italian patients after shoulder surgery for anterior instability (170). ASES: 0.73 (36) and 0.536 (64) in various shoulder problems; 0.76 in rotator cuff diseases (172); 0.89 in instability (172); and ICC = 0.8 in Italian patients after shoulder surgery for anterior instability (170). OSS: ICC = 0.61 (176) and ICC = 0.74 (166) for general shoulder problems in Dutch patients and ICC = 0.68 (169) in Iranian patients; ICC = 0.67 in Italian patients after shoulder surgery for anterior instability (170).…”

DASH: 0.72 in rotator cuff surgery (42) and ICC = 0.73 for various shoulder problems in Spanish patients (168) and ICC = 0.74 in Dutch patients (166).…”
