Brief Summary
Osteoarthritis (OA) is one of the most common diseases and one of the leading causes of disability in the world. People with OA frequently experience sleep disturbances, primarily due to pain. Although insomnia is a known consequence of OA, recent studies have shown that it may also worsen clinical pain by interfering with the body's responses to painful stimuli. This study will evaluate the effectiveness of behavioral treatments for insomnia in reducing sleep disturbances, thereby reducing clinical pain in people with knee OA. The study will test whether improvement in clinical pain are mediated by changes in certain types of pain processing.

Measured at Weeks 4 and 8 and Months 5 and 8
Secondary Outcomes (1)
Reduction in OA-related pain
Measured at Weeks 4 and 8 and Months 5 and 8
Study Arms (6)
1
NO INTERVENTIONParticipants with knee OA who meet research diagnostic criteria for insomnia will partake in Phase 1
2
NO INTERVENTIONParticipants with knee OA who meet research diagnostic criteria for normal sleep will partake in Phase 1
3
NO INTERVENTIONParticipants without knee OA or a pain syndrome who meet research diagnostic criteria for primary insomnia will partake in Phase 1
4
NO INTERVENTIONParticipants without knee OA or a pain syndrome who meet research diagnostic criteria for normal sleep will enroll in Phase I
5
EXPERIMENTALPhase 1 participants with knee OA who meet research diagnostic criteria for insomnia will enroll in Phase 2 of the study and are assigned to receive behavioral desensitization treatment for insomnia
6
EXPERIMENTALPhase 1 participants with knee OA who meet research diagnostic criteria for insomnia will enroll in Phase 2 of the study and are assigned to receive cognitive behavior therapy for insomnia
Interventions
During CBT, participants will learn how to change their sleeping habits and reduce arousal and alertness while trying to sleep. Participants will attend 8 weekly CBT sessions with a psychologist.
The behavioral desensitization treatment is designed to decondition states of arousal that interfere with sleep. Participants will attend 8 weekly behavioral desensitization treatment sessions with a psychologist.
