Abstract

Cognitive intrusions and pre-sleep hyperarousal have been hypothesised to be causal factors in sleep-onset insomnia and there is research evidence which indicates that insomniacs are highly aroused cognitively. This study investigates the content of intrusive pre-sleep cognitions, using live-recordings of spontaneous thoughts, and evaluates their relationship with objectively monitored sleep, using the wrist actigraph, over several nights. 21 subjects with sleep-onset disturbance were recruited through advertisements, and data were obtained for 63 subject nights. This study yields important results concerning the content and quantity of intrusive thoughts which may be associated with sleep-onset difficulties. Implications for cognitively-based treatments for insomnia are discussed.
