RESUMEN
Objective To evaluate the efficacy of sleep regulation technique of thought imprint psychotherapy in lower resistant state (TIP) for the treatment of primary insomnia.Methods 45 hospitalized outpatients with primary insomnia from sleep medical clinic of Guang'anmen Hospital were randomized at a 2 ∶ 1 ratio into a therapy group and a control group using random table.In the therapy group,patients received sleep regudation technique of TIP twice per week.In the control group,patients were asked to take zopiclone 3.75mg per night 30 minutes before bedtime.And the maximum dose can be 7.5mg according to their condition.The treatment lasted one month.Pittsburgh sleep quality index (PSQI) was used to assess sleep quality.Results ① After 4 weeks treatment,the clinical efficacy showed significant difference between the two groups (therapy group was 80％,control group was 33.3％).② Inner group comparison:therapy group was significantly improved in PSQI sleep quality (1.20 ± 0.71),sleep latency(1.53 ±1.01),sleep time(1.23 ±0.82),sleep efficiency(0.90±1.21),sleep disorders (1.30±0.65),sleep medication(0.13±1.36),daytime function (1.67±0.99),total score(8.30±3.19),(P＜0.05); the control group was significantly improved in the PSQI sleep quality(1.60±0.91),sleep latency(1.87±0.64),(P＜0.05).③ Inter group comparison:after treatment,compared to the control group,the therapy group was superior in the sleep latency,sleep time,sleep efficiency,sleep medication,daytime function,and total score ofPSQI (P＜0.05).Conclusion Sleep regulation techmique of thought imprint psychotherapy in lower resistant state can improve sleep quality of primary insomniacs.
