Gender differences in perpetuating factors,experience and management of chronic insomnia

The higher prevalence of insomnia in women has been attributed to biological factors, which are less likely than cognitive and behavioural factors to play a role in perpetuating insomnia. Gender differences in perpetuating factors have not been extensively examined. This study compared men’s and women’s self-reports of factors that perpetuate insomnia; experience of symptoms, perceived severity and impact on daytime functioning; and use of strategies to manage insomnia. Data were collected at baseline, using reliable and valid measures, in a project that evaluated behavioural therapies for insomnia. The sample (N = 739) consisted of women (62.4%) and men (37.6%). Gender differences were found in: (1) perpetuating factors: men took more naps and held more unhelpful beliefs about insomnia, whereas women experienced higher pre-sleep arousal; (2) perception of insomnia severity: higher among women; (3) perceived impact of insomnia: higher fatigue among women; and (4) use of strategies (higher in women) to manage insomnia. Gender differences were of a small size but could be associated with women’s stress, expression of somatic symptoms, and interest in maintaining their own health to meet multiple role demands.
