No differences were observed in the distribution of PQ-B scores by age or socio-economic status, and a barely significant difference was found for the PQ-B distress score by gender, negligible in terms of effect size (Hedges’ g : -0.17; 95%CI: -0.42 to 0.09). 3.1 Internal Consistency and Test-Retest Reliability Internal coherence, as measured by Cronbach’s alpha, was optimal for both the frequency and the distress scores of the PQ-B.
