- BACKGROUND: Although insomnia disorder and social anxiety disorder are among the most prevalent psychiatric disorders, no studies have yet evaluated the use of sequential evidence-based treatment protocols in the population with co-morbid social anxiety disorder and insomnia disorder.AIMS: This study aimed to investigate the effects of sequential treatments on co-morbid insomnia disorder and social anxiety disorder. As depression is a common co-morbid syndrome for both insomnia and social anxiety, a secondary aim was to examine depressive symptoms.METHOD: A single-case repeated crossover AB design was used. Ten participants between 18 and 59 years of age with co-morbid DSM-5 diagnoses of insomnia disorder and social anxiety disorder received sequential treatments with cognitive behavioural therapy (CBT). Seven participants completed the treatment course. The primary outcomes were symptoms of insomnia and social anxiety, and the secondary outcome was symptoms of depression.RESULTS: The effects of CBT on people with co-morbid social anxiety disorder and insomnia disorder were mixed. The majority of participants improved their sleep quality and lessened symptoms of social anxiety and depression. However, participants differed in their degree of improvement concerning all three disorders.CONCLUSIONS: Sequential CBT treatments are potentially effective at decreasing symptoms of social anxiety and insomnia for people with co-morbid social anxiety disorder and insomnia disorder. The variation in outcome across participants makes firm conclusions about the treatment efficacy difficult to draw.

Journal article (other academic/artistic)abstract
- The Minimal Insomnia Symptom Scale (MISS) is a three-item screening instrument that has been found to be psychometrically sound and capable of screening for insomnia among adults and older people. This study aimed to test the measurement properties of the MISS together with an additional item focusing on daytime functioning among adolescents using the Rasch measurement model.

Conference paper (peer-reviewed)abstract
- Introduction : The Minimal Insomnia Symptom Scale (MISS) is a three-item screening instrument that has been found to be psychometrically sound and capable of screening for insomnia among adults and older people. This study aimed to test the measurement properties of the MISS together with an additional item focusing on daytime functioning among adolescents using the Rasch measurement model. Materials and Methods : A cross-sectional design were used, and data from adolescents (age 13-17 years, n=3022) was analyzed using the Rasch measurement model. Results : The MISS had good measurement properties. When replacing the original MISS item “not rested by sleep” with the item “daytime disturbance”, the measurement properties slightly improved. We label this new scale the MISS-Revised (MISS-R). The reliability was significantly better for the MISS-R (0.55) compared to the MISS (0.50). The optimal cut-off was found to be >6 points, both for the MISS and the MISS-R. Conclusions : This study provides general support that both the MISS as well as the MISS-R have good fit to the Rasch model. At this stage, neither the MISS nor the MISS-R can be advocated over the other for use among adolescents, although the MISS-R had slightly better reliability than the MISS. Additional studies are needed to determine the clinically optimal cut-off score for identification of insomnia.

Predictors of Insomnia Among Adolescents a Longitudinal Study
- 2022
-
Conference paper (peer-reviewed)abstract
- Introduction : Insufficient sleep is a public health problem that can impact children’s’ and adolescents’ mental and physical health. This longitudinal study aimed to investigate whether sleep habits, sleep duration and family financial situation among school-aged girls and boys (age 6-10 years) can predict insomnia among female and male adolescents (age 14-16 years). Materials and Methods : School-aged children (n = 522, 49.8% girls) in southern Sweden answered a questionnaire at baseline (age 9.4, SD 1.28 years) and at follow-up (age 14.3, SD 0.69). The survey consisted of questions about tiredness in school, problems waking up, sleep duration, sex, family financial situation and questions from the Minimal Insomnia Symptom Scale - Revised (MISS-R). Multivariate binary logistic regression analyses were used to examine whether tiredness at school, problems waking up, short sleep duration, gender, and family financial situation at baseline predicted insomnia at follow-up. Results : Poor family financial situation (OR: 3.3) and short sleep duration (<10 hours, OR: 2.3) among girls at baseline was associated with insomnia at follow-up. Problems waking up among boys at baseline was associated with insomnia at follow-up (OR: 3.6). Conclusions : Short sleep duration, problems waking up and poor family financial situation in childhood are linked with adolescent insomnia. However, these associations differ between girls and boys, and therefore need to be further investigated to understand adolescent insomnia.
