Recent research in which sleep-onset insomnia has been investigated has emphasized the role of cognitive hyper-arousal, and has led to the finding that excessive worrying and/or problem-solving prior to sleep is associated with delayed sleep-onset latencies. In this study, thirty insomniacs were recruited from the community and assigned randomly to one of three treatment conditions after completing a baseline packet of seven daily sleep diaries and Pre-sleep Arousal Scales (Nicassio et al., 1985). The three treatment conditions were Problem-solving Therapy (n = 10), Progressive Relaxation (n = 10), and a combination of Problem-solving and Progressive Relaxation (n = 10). The problem-solving approach was based on the five-stage model developed by D'Zurilla (1986). The progressive relaxation condition was similar to that found in Bernstein and Borkovec (1973). Treatment was administered for each condition in eight small group sessions over a period of four weeks. The primary dependent measures were the Pre-sleep Arousal Scale and the Daily Sleep Diary, both of which were completed by subjects and mailed to the investigator daily for the duration of the study. / Analysis of baseline correlations revealed significant correlations between baseline sleep-onset latency (SOL) and baseline somatic, cognitive, and overall pre-sleep arousal. The strongest relationship was between SOL and cognitive arousal. Subjects in all three treatment conditions showed significant reductions in sleep-onset latency as a result of treatment. No differences among treatment conditions were found. Improvement was also seen in other sleep variables including number of awakenings, time awake after sleep-onset, morning tiredness, and disturbed sleep. Cognitive arousal, somatic arousal, and overall pre-sleep arousal decreased significantly as a result of treatment, with greater decreases occurring in cognitive arousal than somatic arousal scores. Results were interpreted as largely congruent with previous research emphasizing the importance of cognitive arousal, and theoretical and clinical implications were discussed. / Source: Dissertation Abstracts International, Volume: 52-02, Section: B, page: 1089. / Major Professor: Jack G.
