title: Social Role Participation Questionnaire for patients with ankylosing spondylitis: translation into Dutch, reliability and construct validity.
abstract: OBJECTIVE
  The Social Role Participation Questionnaire (SRPQ) assesses the influence of health on participation in 11 specific and one general participation role across 4 participation dimensions: 'importance', 'satisfaction with time', 'satisfaction with performance' and 'physical difficulty'. This study aimed to translate the SRPQ into Dutch, and assess the clinimetric properties and aspects of its validity among patients with ankylosing spondylitis (AS).
  
  
  METHODS
  Translation was performed using the dual panel approach. For each participation dimension, internal consistency, test-retest reliability (n=31), and construct validity were assessed in 246 patients with AS.
  
  
  RESULTS
  The translation required only minor adaptations. Cronbach αs were α≥0.7. A strong correlation was present between satisfaction with 'time' and 'performance'(r=0.85). Test-retest reliability was satisfactory (κ=0.79-0.95). Correlations with participation domains of the Short-Form Health Survey 36 (SF-36), the WHO Disease Assessment Score II, and generic as well as disease-specific health outcomes (Physical and Mental component scale of the SF-36, Satisfaction With Life Scale, Bath Ankylosing Spondylitis Disease Index (BASDAI), Bath Ankylosing Spondylitis Functioning Index (BASFI)) were at least moderate (r=-0.41 to 0.75) for all dimensions except for 'role importance' where correlations were weak (r≤40). Discriminative ability across 5 self-reported health states was good for all dimensions (p<0.01). The 'general participation' role showed similar reliability and validity for each dimension, as the average of the all 11 roles.
  
  
  CONCLUSIONS
  The Dutch version of the SRPQ is available to help understand social role participation of patients with AS. The dimension 'role importance' measures a distinct aspect of participation. The general participation item was a good global measure of participation.
