RESUMO
The subjective experience in 43 Chinese adults with chronic primary insomnia was assessed using focus groups and insomnia experience diaries. Participants recruited from the community and a sleep clinic were diagnosed with DSM-IV-TR insomnia disorder and had sleep difficulties on 3 or more nights per week for at least 6 months. Six focus groups, of 6-8 participants each, were conducted; it was stopped as thematic saturation emerged in the last 2 groups. Using grounded theory approach, we identified 4 themes and 16 subthemes, covering beliefs about the nature and treatment of insomnia, behavioral responses to insomnia, cognitive-emotional and physiological arousal, and emotional experiences associated with insomnia. The findings are in general compatible with qualitative studies in the West, but some subthemes are influenced by Chinese cultural beliefs and values, in particular, use of the traditional Chinese medicine concept, being modest in sleep expectation, and a letting go attitude. Strategies for cultural adaptation of cognitive-behavioral therapy for insomnia in a Chinese society using patients' subjective experience are discussed.

Stepped care is an increasingly popular treatment model for common mental health disorders, given the large discrepancy between the demand and supply of healthcare service available. In this review, we aim to compare the efficacy and cost-effectiveness of stepped care prevention and treatment with care-as-usual (CAU) or waiting-list control for depressive and/or anxiety disorders. 5 databases were utilized from its earliest available records up until April 2015. 10 randomized controlled trials were included in this review, of which 6 examined stepped care prevention and 4 examined stepped care treatment, specifically including ones regarding depressive and/or anxiety disorders. Only trials with self-help as a treatment component were included. Results showed stepped care treatment revealed a significantly better performance than CAU in reducing anxiety symptoms, and the treatment response rate of anxiety disorders was significantly higher in stepped care treatment than in CAU. No significant difference was found between stepped care prevention/treatment and CAU in preventing anxiety and/or depressive disorders and improving depressive symptoms. In conclusion, stepped care model appeared to be better than CAU in treating anxiety disorders. The model has the potential to reduce the burden on existing resources in mental health and increase the reach and availability of service.

Doxepin, a sedating tricyclic drug, at 3 mg and 6 mg doses was recently approved by the U.S. food and drug administration (FDA) for the treatment of insomnia. The objective of this systematic review was to obtain a precise summary of the efficacy and safety of doxepin as a hypnotic. We searched key databases and trial registers up to March 2014 and contacted pharmaceutical companies and the FDA for unpublished data. A total of nine randomized placebo-controlled trials were analyzed. Six studies were on doxepin 1-6 mg/d, two on doxepin 25-300 mg/d, and one on ramelteon 8 mg and doxepin 3 mg combined. All low-dose studies were industry-sponsored. We found that low-dose doxepin had a small to medium effect size against placebo for sleep maintenance and sleep duration but not for sleep initiation at both immediate and short-term posttreatment. There was no significant next-day residual effect with low-dose doxepin. Headache and somnolence were the most common side effects. We concluded that low-dose doxepin for 1-2 nights appeared to be safe and effective in improving sleep. However, a clear conclusion on its short-term benefits and risks as well as withdrawal effects was not possible due to the small number of studies.

OBJECTIVE: To examine the efficacy and safety of hypnotherapy for insomnia as compared to placebo, pharmacological or non-pharmacological intervention, or no treatment. METHODS: A systematic search on major electronic databases was conducted up until March 2014. Inclusion criteria are: (1) randomized controlled trials (RCTs) or quasi-RCTs; (2) intervention targeted at improving sleep; (3) hypnosis as an intervention; and (4) English language articles. Sleep diary variable is the primary outcome measure. RESULTS: Six RCTs of hypnotherapy and seven on autogenic training or guided imagery, comprising 502 subjects, were included. Eleven of the 13 studies had low methodological quality, as indicated by a modified Jadad score below 3, and high risks of bias in blinding and design of the control interventions. No adverse events related to hypnosis were reported, though seldom investigated. Meta-analyses found hypnotherapy significantly shortened sleep latency compared to waitlist (standardized mean difference, SMD=-0.88, 95% confidence interval (CI): -1.56, -0.19, P=0.01, I(2)=15%), but no difference compared to sham intervention (SMD: -1.08, 95% CI: -3.15, 0.09, P=0.31, I(2)=90%). Similar results were found for autogenic training or guided imagery (SMD with waitlist=-1.16, 95% CI: -1.92, -0.40, P=0.003, I(2)=0%; SMD with sham intervention=-0.50, 95% CI: -1.19, 0.19, P=0.15, I(2)=0%). CONCLUSIONS: Generalizability of the positive results is doubtful due to the relatively small sample size and methodological limitations. Future studies with larger sample size and better study design and methodology are called for.

Self-help cognitive-behavioral therapy for insomnia (CBT-I) is an acceptable, low-intensity treatment in a stepped care model for insomnia. We tested the application of self-help CBT-I in a Chinese population. 312 participants with self-report of insomnia associated with distress or daytime impairment 3 or more nights per week for at least 3 months were randomized to self-help CBT-I with telephone support (SHS), self-help CBT-I (SH) and waiting-list (WL). The program was Internet-based with treatment materials delivered once per week, and lasted for 6 consecutive weeks, while the telephone support was limited to 15 min weekly. Mixed-effects analyses found significant group by time interaction in sleep and sleep-related cognitions at immediate and 4-week posttreatment. Post-hoc pairwise comparison with WL revealed that both SHS and SH had significantly higher sleep efficiency at immediate (p = .004 and p = .03, respectively) and 4-week posttreatment (p = .002 and p = .02, respectively) and lower insomnia and dysfunctional beliefs scores. The SHS group had additional improvements in sleep onset latency and sleep quality. Benefits with self-help CBT-I were maintained at 12-week posttreatment, but attrition rate was about 35%. Internet-based self-help CBT-I was effective and acceptable for treating insomnia in the Chinese population. A brief telephone support further enhanced the efficacy.
