Abstract | Insomnia is the most common sleep problem affecting youths worldwide. Insomnia in
youth is closely associated to a variety of negative consequences, including mood
disturbances and impairments in daytime functioning. In particular, fatigue and lower quality
of life are linked to impaired daytime functioning in youths. Yet, the effect of insomnia on
fatigue level and quality of life were rarely examined in the youth population. Moreover,
there is a high co-morbidity of insomnia and depression in youths but the optimal treatment
approach to address this common comorbidity remained unclear. This thesis aimed to
evaluate the impacts of youth insomnia on fatigue and quality of life, and to evaluate the
efficacy of two cognitive behavioural approaches, i.e. cognitive behavioural therapy for
insomnia (CBT-I) and cognitive behavioural therapy for depression (CBT-D), in treating
youths with comorbid insomnia and depression.
Study 1 was a cross-sectional study that involved a sample of university students
(n=725). Participants completed a battery of questionnaires to assess their insomnia severity
(as measured by Insomnia Severity Index), depressive symptoms (as measured by Depression
Anxiety Stress Scales-Depression Scale), fatigue (as measured by Multidimensional Fatigue
Inventory) and quality of life (as assessed by KIDSCREEN-27). The results indicated that
42.7% of the participants had insomnia symptoms, which were associated with depressive
mood, fatigue and lower quality of life. In addition, fatigue was found to mediate the
relationship between insomnia and depressive symptoms, and between insomnia and quality
of life. Study 2 was a randomized controlled trial that examined the effects of group-based
CBT-I and CBT-D on insomnia, depression, fatigue and quality of life in youths with
comorbid insomnia and depression (n=112). Participants in both active treatment groups were
found to show significant improvements in sleep, depression, fatigue and quality of life at post-treatment one-week and one-month follow-ups, as compared to the waitlist control
group. Both groups achieved a high remission rate of overall clinical symptoms (insomnia
and depression) at the one-month follow-up (CBT-D: 77.8% and CBT-I: 74.1%). The results
suggested sleep-focused treatment is efficacious in comorbid insomnia and depression
management in young people. Further studies with longer follow-up periods are needed to
examine whether the beneficial effects of CBT-I on improving mood, fatigue and quality of
life could sustain over time in youths.
