Brief Summary

Many children with ADHD suffer from sleep disorders and dysfunction, which may affect development and well-being. According to the clinicians, some children find relief from restlessness and difficulty sleeping by using weighted blankets which have been proposed to reduce restlessness and stress via sensory integration and to calm the child by stimulating the sense of touch, muscles and joints. However, evidence for an effect on sleep is scarce, and only one RCT has investigated the effect of weighted blankets among children with ADHD. Using a RCT design, the aim is to investigate the effect on sleep disorders and dysfunction in children with ADHD aged 5-12 years by (1) using a weighted blanket during night and daytime in addition to usual treatment, compared to (2) usual treatment and a non-weighted sham blanket, with the primary outcome being differences in total sleep time. Results will support health- and social professionals who are involved in the treatment of children with ADHD.

Detailed Description

Over the past decade, interest in the relationship between sleep difficulties and ADHD has increased, with evidence showing that sleep problems are very common among school children with ADHD, affecting nearly three-quarters. Sleep problems may worsening daytime behaviors and may also affect the overall wellbeing of the family, leading to poorer parental mental health and higher stress. According to the clinicians, some children find relief from restlessness and difficulty sleeping by using weighted blankets which have been proposed to reduce restlessness and stress via sensory integration and to calm the child by stimulating the sense of touch, muscles and joints. However, evidence for an effect on sleep is scarce, and only one RCT has investigated the effect of weighted blankets among children with ADHD. Using a RCT design, the aim is to investigate the effect on sleep disorders and dysfunction in children with ADHD aged 5-12 years by (1) using a weighted blanket during night and daytime in addition to usual treatment, compared to (2) usual treatment and a non-weighted sham blanket, with the primary outcome being differences in total sleep time.

The study is designed as a superiority trial: a parallel group, randomised controlled trial, where participants are randomised to one of two study arms 1:1. The sample consists of 340 participants, divided into two groups. After randomisation each participant will stay in their assigned treatment arm during the entire study. For each study participant, the active intervention period is 28 days with assessment of primary and secondary outcomes at baseline and after 28 days of intervention. Thereafter participants will be followed through national health registers.

The trial will take place at the Child and Adolescent Mental Health Center, Mental Health Services in the Capital Region of Denmark. This center is providing assessment and treatment of children and adolescents with psychiatric disorders.

Arm && Interventions

Group	Intervention	Description
Non-weighted blanket	Non-weighted blanket	The control comparator group will receive a sham intervention in the form of a non-weighted blanket. as an add on to usual treatment.
Weighted blanket	Weighted blanket	The intervention group will receive a weighted blanket classified as a medical device class 1 as an add on to usual treatment.

Primary Outcome Measures

Name	Time	Method
Changes in total sleep time (average minutes per day)	Week 0 and 4	Total sleep time (TST) is defined as the time of total sleep episode minus the awake time (the entire time spent sleeping) and reported in minutes per day. TST per day will be measured using actigraphy in form of MotionWare 8 (The MotionWare 8®-CamNtech MotionWare).

Secondary Outcome Measures

Name	Time	Method
Adverse events (Number of participants with adverse events)	During intervention	Number of participants with adverse events (AE).
Changes in sleep efficiency (percentage)	Week 0 and 4	Sleep efficiency (SE) is measured using actigraphy and is the actual sleep time expressed as a percentage of the total time in bed (the time elapsed between "lights out" and "get up time"). SE will be reported as minutes per day.
Changes in ADHD core symptoms (score point)	Week 0 and 4	ADHD core symptoms will be measured with Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS) parent version. It is a 26-item questionnaire including the 18 original ADHD-RS-IV items supplied with 8 conduct problem items. All items are rated on a 4-point Likert scale (0-3), where 0 represents never or rarely, 1 is sometimes, 2 is often, and 3 is very often. From the item scores, a total score ranging 0-78 will be calculated. Further, three sub-scores will be calculated; inattentive scale: range 0-27, hyperactive/impulsive scale: range 0-27, and conduct scale: range 0-24.
Changes in functional impairment	Week 0 and 4	Functioning impairment will be measured using Weiss Functional Impairment Rating Scale (WFIRS-P). The WFIRS-P is a 50-item scale assessment tool where caregivers rate the impact of their child's emotional or behavioural problems in the previous month on six separate domains: (A) Family (ten items); (B) School and learning; (C) Life skills; (D) Child's self-concept; (E) Social activities; and (F) Risky activities. Each item is rated on a four-point scale from 0 ('never or not at all') to 3 ('very often or very much') or rated as 'not applicable'. The instrument uses a likert scale such that any item rating 2 or 3 is clinically impaired. The mean of all scored items for each domain will be calculated. Furthermore, a single overall WFIRS-P score will also be calculated as the average of the six domain scores.
Changes in sleep onset latency (average minutes per day)	Week 0 and 4	Sleep onset latency (SOL) refers to the period of time between turning lights out to go to sleep and falling asleep. SOL will be measured using actigraphy which includes a button that should be pressed by a caregiver when the lights are turned off. SOL will be reported as minutes per day.
Changes in number of awakenings (numbers per night)	Week 0 and 4	Wake after sleep is defined as number of minutes scored as wake during sleep period and will be measured using actigraphy.
Changes in child quality of life (score point)	Week 0 and 4	Child quality of life will be measured using The World Health Organisation- Child Well-Being Index (WHO-5). The WHO-5 Child Wellbeing Index is a simple self-reported measure of children's psychological wellbeing. The tool consists of five statements describing a positive state. The child is asked to say how often they felt that way during the past two weeks, by selecting one of the following options: All the time, Often, Sometimes, Rarely or Never.
Changes in parental stress (score point)	Week 0 and 4	Changes in parental stress is measured by the Parental Stress Scale (PSS). The PSS is an 18-item questionnaire assessing parents' feelings about their parenting role, exploring both positive aspects (e.g. emotional benefits, personal development) and negative aspects of parenthood (e.g. demands on resources, feelings of stress). Parents can agree or disagree in terms of their typical relationship with their child or children. Responses are scored as follows: strongly disagree, disagree, undecided, agree, strongly agree. To compute the parental stress score, items 1, 2, 5, 6, 7, 8, 17, and 18 should be reversely scored as follows: (1=5) (2=4) (3=3) (4=2) (5=1). The item scores are then summed. Parental stress scores range from 18 to 90, with lower scores indicating lower levels of parental stress.
Serious adverse events (Number of participants with serious adverse events)	During intervention	Number of participants with serious adverse events (SAE).
