Abstract
The present study investigated the relationship between sleep onset insomnia and coping. In Study 1, the authors classified coping with sleep onset insomnia into three factors using factor analyses. These factors were as follows. Factor 1: inhibition of cognitive activity; Factor 2: engaging in other activity than sleep; and Factor 3: activation of cognitive activity. In Study 2, the authors examined the relationship among coping, pre-sleep cognitive activity, and sleep onset insomnia among 355 university students. Results indicated that all coping positively correlated with pre-sleep cognitive activity and sleep onset insomnia. A path analysis showed two paths leading sleep latency. One was an indirect path representing that cognitive coping was significantly related to pre-sleep cognitive activity, and the other was a direct path demonstrating that behavioral coping was significantly related to sleep latency. These results showed that improper coping had no functional effect for sleep onset insomnia. Development of cognitive behavior therapy for insomnia focused on decrease in improper coping, and introduction of alternative behavior is necessary, is expected.
