Group cognitive behavioural therapy for insomnia: Effects on sleep and depressive symptomatology in a sample with comorbidity.
Annika Norell-Clarke,Markus Jansson-Fröjmark,Maria Tillfors,Fredrik Holländare,Ingemar Engström +4 more
TL;DR: Group CBT-I is an efficient form of insomnia-treatment for people with insomnia comorbid with depressive symptomatology and the mixed results regarding depression outcomes warrants replication and further studies into treatment mechanisms.
Journal ArticleDOI
Psychometric Properties of an Insomnia-Specific Measure of Worry: The Anxiety and Preoccupation about Sleep Questionnaire
Markus Jansson-Fröjmark,Allison G. Harvey,Lars-Gunnar Lundh,Annika Norell-Clarke,Steven J. Linton +4 more
TL;DR: The findings suggest that the APSQ is a psychometrically sound instrument for assessing worry in insomnia and demonstrated convergent validity with measures on cognitive arousal, sleep-related beliefs, anxiety, and depression.
Journal ArticleDOI
Cognitive Behavioural Therapy for Insomnia in Psychiatric Disorders.
TL;DR: Recent studies on the effects from CBT-I on sleep, daytime symptoms and function and psychiatric comorbidities for people with anxiety, depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder are reviewed.
Journal ArticleDOI
Psychometric properties of the Pre-Sleep Arousal Scale in a large community sample.
TL;DR: Though acceptable psychometric properties were established for the PSAS, the cognitive subscale's focus upon general pre-sleep arousal and the relatively low variance accounted for calls for further work on and a possible re-conceptualization of the PS AS.
Journal ArticleDOI
Cognitive processes and their association with persistence and remission of insomnia: Findings from a longitudinal study in the general population
Annika Norell-Clarke,Markus Jansson-Fröjmark,Maria Tillfors,Allison G. Harvey,Steven J. Linton +4 more
TL;DR: The findings support that certain cognitive processes may be associated with persistence and remission of insomnia, and use of safety behaviours over time increased the likelihood of remission from insomnia.
