Abstract:
The present paper reviews theories and empirical research concerning the role of psychological processes in insomnia. It is argued that two kinds of psychological processes are involved in insomnia: sleep-interfering processes and sleep-interpreting processes. A theoretical model is sketched, where it is argued that psychological vulnerability factors may predispose the individual to (1) respond with sleep-interfering processes to stressful life events, and to (2) engage in dysfunctional sleep-interpreting processes. Examples of the first kind of variables are arousability, slow recuperation after stress, worrying, and emotional conflicts in relation to significant others; examples of the latter are sleep-related beliefs, attitudes, and perfectionistic standards.
