title: Pathways to inflated responsibility beliefs, responsibility attitudes and obsessive-compulsive symptoms: factor structure and test of a mediational model.
abstract: BACKGROUND
  Inflated responsibility has been hypothesized as an important influence on OCD symptoms. According to Salkovskis and colleagues (1999) there are in turn five developmental pathways that lead to inflated responsibility. Coles and Schofield (2008) proposed the Pathways to Responsibility Beliefs Scale (PIRBS) as a measure of these pathways.
  
  
  METHODS
  In the present study the psychometric properties of an Icelandic translation of the PIRBS were evaluated and its factor structure was studied in a confirmatory factor analysis. Further it was tested whether responsibility mediated between pathways to responsibility beliefs and OCD symptoms.
  
  
  RESULTS
  While neither a four nor a five-factor structure of the PIRBS was found to be wholly satisfactory; support for the latter was slightly better. Correlations of the PIRBS scales with measures of responsibility and obsessive-compulsive disorder symptoms were moderate as expected. Support was found for a mediating role of responsibility attitudes between pathways measured by the PIRBS and OCD symptoms in support of Salkovskis and colleagues' theory (1999).
  
  
  CONCLUSIONS
  The PIRBS is a promising approach to study the developmental precursors of inflated responsibility and OCD symptoms but its factor structure may need a revision.
