Abstract:
Context: The aim of this research was to identify whether the underlying cognitive mechanisms suggested to contribute to the maintenance of depression are present in a community sample of people who report insomnia. Design: In a cross section study, rumination, inhibition and set switching cognitive processes were compared in a community sample of 79 participants aged 18-59 years. The Insomnia Severity Index (ISI) was used to identify subjective ‘good’ and ‘poor sleepers’. Using Morin et al., (2011) recommendations, a cutoff score of 10 was used to differentiate between this community sample of good (n = 43) and poor(n = 36) sleepers. Measures: Assessments included: the ISI; Pittsburgh Sleep Quality Index; Epworth Sleepiness Scale; The Ruminative Response Styles questionnaire; Pre Sleep Arousal Scale; Spielberger’s State/Trait Anxiety Inventory and the Beck Depression Inventory. The task-switching paradigm described by Mayr and Keele (2000), was used to design a computer-based program to obtain an index of set shifting and an index of inhibition of previously relevant information. Main findings: Between group comparisons were made using a one-way ANOVA. Data replicated previous findings showing people with poor sleep differ significantly in their psychological makeup compared to good sleepers. Data show a distinct psychological profile that has been found in previous research when comparing a community sample of people with and without poor sleep.
