The relationship between cognitive failures, psychoneurotic symptoms and sex

As Broadbent et al's (1) original analysis of the relationship between the Cognitive Failures Questionnaire (CFQ) and the Middlesex Hospital Questionnaire (MHQ) was conducted on an altered version of the MHQ, the present study undertook this same analysis using the full MHQ. In addition, the relationship was examined to see if it was mediated by the differences in the scoring of males and females on each questionnaire. Our results support and strengthen Broadbent et al's conclusion that high rates of cognitive failure are associated with psychoneurotic symptoms. The sex difference on the CFQ is discussed in terms of vulnerability to stress to account for the higher incidence of psychoneurotic symptoms in females.
