Outcome domains and outcome measures used in studies assessing the effectiveness of interventions to manage non-respiratory sleep disturbances in children with neurodisabilities: a systematic review

Low Doses of Melatonin to Improve Sleep in Children with ADHD: An Open-Label Trial

OBJECTIVE

Only a few studies assessing the sleep effects of low doses of melatonin (aMT) have been performed in the past, most of them in adults, and only one in subjects with attention-deficit/hyperactivity disorder (ADHD). The aim of this study was to provide evidence of the changes induced by aMT doses as low as 1 mg in the sleep pattern of pediatric patients with ADHD under treatment with methylphenidate (MPH).

METHODS

Children and adolescents (7-15 years) with ADHD who were receiving extended-release MPH were recruited. A seven-week sleep diary was collected prior to starting a four-week treatment with 1 mg of aMT (30 min before bedtime). Seven-day actigraphic assessments of sleep were performed before and after treatment.

RESULTS

Twenty-seven patients (17 males, 62.96%) participated in the study, who had been receiving MPH for 1.57 (1.11) months. A significant increase in sleep duration (TST) was observed after one month of treatment (463 (49) min to 485 (41) min; p < 0.040), with nonsignificant improvements in sleep-onset latency (SOL), nocturnal awakenings, or sleep efficiency. Only minor adverse effects were reported.

CONCLUSION

Low doses of melatonin (1 mg) are able to increase TST in children and adolescents with ADHD receiving treatment with psychostimulants, with an adequate tolerability profile. Further placebo-controlled trials adjusting the time of aMT administration to the individual circadian profile should explore the effects of low doses of this hormone to shorten SOL in this population of patients.

Sleep interventions for children with attention deficit hyperactivity disorder (ADHD): A systematic literature review

OBJECTIVE/BACKGROUND

Healthy sleep is particularly important for children with attention deficit hyperactivity disorder (ADHD), as sleep disturbances might aggravate disease symptoms. This review aims to synthesize and report evidence on the effectiveness of sleep interventions in increasing sleep, quality of life (QoL), and ADHD symptoms among children with ADHD.

PATIENTS/METHODS

The systematic literature review follows the Cochrane Collaboration methodology recommendations for literature reviews. Four databases were used based on the population, intervention, control and outcome (PICO) framework. Controlled trials with minimum 20 children in each group, aged 6-18, and published from 2005 and onwards were included. Results from the studies were reported in forest plots and three of the seven review outcomes were synthesized in meta-analyses.

RESULTS

The search identified 7710 records; of which 4808 abstracts were screened. After fulltext-screening of 99 papers, eight papers from five studies were included. The studies included behavioral sleep interventions and pharmacological interventions using melatonin and eszopiclone. For six of the seven outcomes, the effect sizes were small to moderate and the certainty of the evidence was low. For one outcome, sleep disturbances, the effect size was a moderate -0.49 standardized mean differences (95% confidence interval -0.65;-0.33), with a moderate certainty of evidence for the behavioral interventions for children aged 5-13 years with ADHD.

CONCLUSIONS

This review identified few and heterogeneous studies. A moderate certainty of evidence for a moderate effect size was only obtained for sleep disturbances from the behavioral interventions. A low certainty of the evidence for a moderate effect size was found for the total sleep time from the pharmacological intervention using melatonin and one behavioral intervention, which indicates that these sleep interventions impact sleep quantity and quality among children with ADHD.

Youth and family engagement in childhood disability evidence syntheses: A scoping review

Within the last decade, stakeholder engagement in research has become increasingly popular in childhood disability research; however, literature on the engagement of youth with neurodisabilities and their families in evidence syntheses is underdeveloped. Involving patients as partners in research has the potential to improve applicability and relevance of the research and benefit patient partners (e.g. enhanced self-esteem, increased research knowledge and skills); however, the methods, challenges, outcomes and recommendations of engaging youth with neurodisabilities and their families in evidence syntheses are unknown. Two parents of youth with complex disability needs were engaged as partners throughout this review. Following methods outlined by Arksey and O'Malley (2005), the primary research question in this scoping review is twofold: (i) what activities have youth with neurodisabilities and their families been engaged in as part of evidence syntheses and (ii) what were the outcomes of that engagement? After full text review of 369 articles, nine articles were included. Youth and families were engaged prior to the evidence synthesis and at every stage in the project, most often during data analysis where they contextualized the findings. Youth and family engagement were not formally evaluated; however, positive outcomes were reported by parents and researchers. Challenges such as increased time, sustaining engagement, and parents' dissatisfaction with their level of involvement were reported. Recommendations centred around providing partners with information, building relationships via social media, and openly communicating about roles, feedback and logistics. Childhood disability researchers should be aware of how they can increase engagement opportunities at all stages of evidence syntheses and how they might improve accessibility for youth with neurodisabilities and their families. Further research is needed to solidify a unified framework for conduct and reporting of youth and family engagement in evidence syntheses.
