ABSTRACT
This chapter aims to help clinicians assess Insomnia and other sleep disorders in the context of psychotic disorders. It outlines different types of assessment method and make particular mention of situations when certain assessment procedures are not well tolerated, or may lack validity, in people with psychotic disorders. Assessing sleep routine can provide clues about perpetuating factors that reduce sleep drive and the presence of circadian rhythm disruptions. Sleepiness is an individual’s capacity to fall asleep, and it can be assessed by the client being asked how likely they would be to fall asleep in various situations. Assessment of self-efficacy involves asking the client if they believe they can work to improve their sleep, or if they believe it to be unchangeable. Clients who are hypomanic or manic may skew their ratings more positively, whereas others may lack insight into the severity of their sleep problems.
