Initial evaluation of an Internet intervention to improve the sleep of cancer survivors with insomnia.

Objective: Insomnia is a common complaint among cancer survivors. Fortunately, cognitive-behavioral therapy for insomnia (CBT-I) has been shown to be an effective treatment in this population. However, it is rarely implemented given its limited availability.

Efficacy of an Internet-based behavioral intervention for adults with insomnia.

Context: Insomnia is a major health problem with significant psychological, health, and economic consequences. However, availability of one of the most effective insomnia treatments, cognitive behavioral therapy, is significantly limited. The Internet may be a key conduit for delivering this intervention.

Development and Perceived Utility and Impact of an Internet Intervention for Insomnia.

Insomnia is a major health problem, with significant psychological, health, and economic consequences. Studies have demonstrated that cognitive-behavioural therapy can effectively treat insomnia; however, treatment availability is limited by many factors, including a lack of trained clinicians. One potential way to overcome these barriers is to use the Internet to deliver treatment.

Understanding placebo, nocebo, and iatrogenic treatment effects.

Placebo and nonplacebo treatments have both positive and negative effects on patient outcomes. To better understand the patterning of treatment effects, three specific interventions will be discussed that are reported to produce more harm than benefit: critical incident stress debriefing, group therapy for adolescents with conduct disorders, and psychotherapy for dissociative identity disorder. In each case, there is an interaction between mechanisms thought to underlie both placebo and specific treatment effects.
