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.
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.
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).
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.
责任膨胀被假设为 OCD 症状的一个重要影响因素。根据 Salkovskis 及其同事（1999 年）的说法，有五个发展途径会导致责任膨胀。Coles 和 Schofield（2008 年）提出了责任信念途径量表（PIRBS）来衡量这些途径。
本研究评估了 PIRBS 的冰岛语翻译的心理测量特性，并在验证性因素分析中研究了其因素结构。进一步检验了责任是否在责任信念途径和 OCD 症状之间起中介作用。
虽然 PIRBS 的四因素和五因素结构都不完全令人满意，但后者的支持稍好一些。正如预期的那样，PIRBS 量表与责任和强迫症症状的测量值之间存在中度相关。在支持 Salkovskis 及其同事（1999 年）理论的前提下，发现 PIRBS 测量的责任途径和 OCD 症状之间的责任态度起着中介作用。
PIRBS 是研究责任膨胀和 OCD 症状发展前因的一种有前途的方法，但它的因素结构可能需要修订。
