AB  - BACKGROUND: Psychological symptoms are frequently present in patients scheduled 
      for shoulder surgery. The perception of functional disability, activity level and 
      pain in the shoulder is negatively influenced by psychological symptoms, which 
      leads to higher scores of the Disabilities of the Arm, Shoulder and Hand (DASH) 
      questionnaire. The aim of this study was to determine the influence of 
      psychological symptoms on the minimal clinically important difference (MCID) of 
      the DASH score in patients after shoulder surgery. METHODS: In this prospective 
      longitudinal cohort study, 176 patients were included. Group 1 (32 patients) had 
      symptoms of psychological disorders before and after surgery; group 2 had no 
      symptoms of psychological disorders (110 patients). In the remaining patients (34 
      patients), psychological disorders changed after surgery. Clinical outcome was 
      measured with the change of DASH score and anchor questions for perceived 
      improvement of pain and function after surgery. Symptoms of psychological 
      disorders were identified with the Four-Dimensional Symptom Questionnaire. An 
      anchor-based mean change score technique was used to determine the MCID of the 
      DASH score. RESULTS: DASH scores before and 12 months after shoulder surgery were 
      significantly higher in patients with symptoms of psychological disorders; change 
      of DASH score was not different between the two groups. The MCID of the DASH 
      score was 13.0 [SD 20.7] in the group with symptoms of psychological disorders 
      and 12.7 [SD 17.6] in the group with no symptoms of psychological disorders. We 
      observed no difference (p = 0.559) in the MCID between the group with and the 
      group without symptoms of psychological disorders. CONCLUSION: Symptoms of 
      psychological disorders had a negative effect on the DASH score but no influence 
      on the MCID of the DASH score. The DASH score could be used in future studies to 
      assess the influence of psychological factors on the clinical outcome of 
      treatment.
