TI  - Severity and functional disability of patients with occupational contact 
      dermatitis: validation of the German version of the Occupational Contact 
      Dermatitis Disease Severity Index.

AB  - BACKGROUND: The Occupational Contact Dermatitis Disease Severity Index (ODDI) was 
      designed in Australia to measure severity and functional disability in patients 
      with occupational contact dermatitis (OCD) of the hands. The ODDI was translated 
      into the German language with a linguistic validation process. The psychometric 
      properties of the German version of the ODDI are still unclear. OBJECTIVES: To 
      report the linguistic validation procedure and to perform a psychometric 
      validation by investigating the validity and reliability of the German ODDI 
      version in a sample of patients with OCD. METHODS: Data were drawn from the 
      baseline assessment (T0) and first follow-up (T1) of the German chronic hand 
      eczema (CHE) registry (CARPE). Spearman correlations of the ODDI with reference 
      measures were computed to assess validity. Cronbach's alpha was calculated as a 
      measure of internal consistency, and the intraclass correlation coefficient (ICC) 
      was calculated to assess retest reliability. The smallest real difference (SRD) 
      and minimal clinically important difference (MCID) were calculated to assess 
      sensitivity to change. Physician Global Assessment (PGA) was used as an anchor 
      for the MCID. RESULTS: Four hundred and twenty-two patients (54.5% female, mean 
      age 45.1 years) were included for analysis. Cronbach's alpha was found to be 
      0.73. The ICC was 0.79. Correlations between the ODDI total and the Dermatology 
      Life Quality Index (rho = 0.36), and between PGA (rho = 0.48) and 
      patient-assessed disease severity (rho = 0.40), were of moderate strength. The 
      MCID (1.29) was found to be smaller than the SRD (1.87). CONCLUSIONS: The German 
      ODDI version is reliable and valid for the measurement of functional impairment 
      and disease severity in patients suffering from OCD.
