Efficacy of Brief Behavioral Therapy for Insomnia （BBT-I） in patients suffering Paradoxical insomnia / 中风与神经疾病杂志

ABSTRACT

@#To explore the effect of BBT-I on subjective insomnia and its influencing factors. Methods 60 primary insomnia patients were collected in outpatient department，and divided into two groups：Subjective insomnia group （SI group） and non-subjective insomnia group （NSI group） by sleep data collected by standard polysomnography monitoring and Pittsburgh Sleep Quality Index （PSQI），sleep diaries during the intervention were collected，and the Pre Sleep Arousal Scale（PSAS），Brief Version of Dysfunctional Beliefs and Attitudes About Sleep （DBAS） and the Sleep Hygiene Practice Scale（SHPS） were collected to evaluate the influencing factors related to sleep attitudes，beliefs and behaviors of patients. All patients received BBT-I for 4 weeks，and collected the sleep diaries and PSQI 1 week before and 1 week after treatment. Results Compared with NSI group，SI group had higher arousal index（P<0.05）；compared with NSI group，SI group had lower scores in factor 3 indicated as drug belief and factor 4 representing anticipation of sleep in DBAS，that is，there were more irrational beliefs in SI （P<0.05）.Intragroup comparison showed that there were statistically significant differences insleep latency、sleep efficiency，daytime function and PSQI score in SI group before and after treatment （P<0.05），and there were statistically significant differences in SE difference before and after intervention between SI group and NSI group （P<0.05）.In the subjective insomnia group，daytime functional difference before and after intervention was negatively correlated with the first factor in DBAS（r=0.270，P=0.037）. daytime functional difference before and after intervention was negatively correlated with PSAS（r=0.268，P=0.039）；The difference of sleep latency before and after intervention was negatively correlated with physiological stimulation of PSAS（r =0.288，P=0.042）. Conclusion Compared with nonsubjective patients，subjective insomnia patients have higher arousals and more irrational beliefs and attitudes.BBT-I may improve sleep latency/、sleep efficiency，daytime function and sleep sensation in subjective insomnia patients.
