Efficacy of group cognitive behavioral therapy for youth anxiety and insomnia
This study aims to compare the efficacy of group-based CBT-I and CBT-A in reducing the severity of insomnia and anxiety symptoms, as well as other depressive symptoms and daytime functioning (e.g. sleepiness, fatigue) in adolescents with comorbid insomnia and anxiety, when compared with the waiting-list control. Additionally, this study investigates the potential change of general and sleep-related attentional bias after the group-based CBT-I and CBT-A treatment.
Treatment Study for Insomnia in Pregnant Women with Comorbid Insomnia and Depression
This study aims to test the efficacy of group-based cognitive behavioural therapy for insomnia (CBT-I) and app-based CBT-I (developed by a group of psychiatrists and clinical psychologists) in combination with usual care (UC) in reducing the severity of insomnia and depression in pregnant women with comorbid insomnia and depression, when compared with UC plus group-based health-related psychoeducation control. This study also examines the effects of group-based CBT-I and app-based CBT-I on subjective and objective sleep and mood measures, quality of life measures as well as mother-infant-relationship.
Treatment study for Depression in Youths with Delayed Sleep Phase (DELAY Trial)
The goal of this prospective randomised controlled trial is to examine the effects of cognitive behavioural therapy and bright light therapy in youths with unipolar depression and evening chronotype. The study aimed to examine the efficacy of CBT-D and CBT-D with bright light therapy in reducing depression severity in adolescents with depression and eveningness?
Treatment Study for Insomnia in Adolescents with ADHD
This study aims to evaluate the efficacy of cognitive behavioural therapy for insomnia (CBT-I) in reducing insomnia severity in adolescents with ADHD and insomnia when compared with the waiting-list control. This study also examines the effects of the treatment on adolescents’ sleep, emotion regulation ability, and psychological well-being.
An Eye-tracking Study on Attentional Bias in Insomnia
This study proposes to compare the level of threat- and sleep-related attentional bias in youth with and without insomnia. More importantly, we comprehensively analyze individuals’ attentional eye-gaze patterns in response to threat- and sleep-related information using advanced eye-tracking technology.
Sleep and Cognitive Functioning among Elderly
This study aims to better delineate the potential differences in the association between sleep and cognitive functioning among Chinese elderly with or without sleep disturbances, especially insomnia. Data will be collected using subjective and objective measures of sleep (polysomnography) and cognitive functioning (computerized cognitive tasks).
Treatment Study for Insomnia using digitally delivered CBTI
This study aims to examine the efficacy of group-based CBT-I and app-based CBT-I (developed by a group of psychiatrist and clinical psychologists) in reducing insomnia severity in adolescents, when compared with the waiting-list control. This study also examines the effects of group-based CBT-I and app-based CBT-I on the measures of mood symptoms and daytime functioning (e.g. sleepiness, fatigue), as well as subjective and objective sleep measures.
