Sleep Outcomes for Parents of Children With Neurodevelopmental Disabilities: A Systematic Review

An Open-Label Pilot Trial of a Brief, Parent-Based Sleep Intervention in Children With ADHD

OBJECTIVE

To assess the effects of a brief parent-based behavioral sleep intervention in children with ADHD.

METHODS

Families with a child with ADHD and parent-reported sleep problems received a brief parent-based sleep intervention, which involved two one-to-one consultation sessions and one telephone follow-up with the parent/caregiver. Child's sleep and clinical symptoms, and parental sleep and daytime functioning were assessed at baseline, 2-week post-intervention, and 3-month follow-up.

RESULTS

Sixty eligible families (mean age of the child: 9.4 ± 1.5 years; boys: 75%) were recruited, and 43 (72%) completed the whole intervention. The intervention resulted in significant improvements in the child's sleep, clinical symptoms, and parental sleep and parenting stress, and these improvements were generally maintained at 3-month follow-up.

CONCLUSION

The findings supported the promising effects of a brief parent-based sleep intervention on improving sleep and clinical symptoms in children with ADHD and parental sleep and parenting stress. Further randomized clinical trials with long-term follow-up are needed to test the robustness of the effectiveness of the intervention.

Sleep Quality and Evening Salivary Cortisol Levels in Association with the Psychological Resources of Parents of Children with Developmental Disorders and Type 1 Diabetes

BACKGROUND

Sleep deprivation can decrease parental well-being and degrade mental and physical health in parents of children with chronic illness. The aim of this study was to explore the associations of sleep quality, psychological stress perception, and evening salivary cortisol concentration with self-esteem, optimism and happiness in parents of children with type 1 diabetes and developmental disorders compared to parents of healthy, typically developing children.

METHODS

We studied 196 parents of children with chronic conditions, including autistic spectrum disorder (N = 33), cerebral palsy (N = 18), Down syndrome (N = 33), and diabetes mellitus type 1 (N = 40) and parents of healthy children (N = 72). We evaluated parental sleep quality, evening salivary cortisol levels, self-esteem, optimism and happiness. Multiple linear regression models were used to assess associations between variables.

RESULTS

Compared with those of the control group, the parents of children with autistic spectrum disorders had higher evening cortisol concentrations (β = 0.17; p = 0.038) and lower perceptions of happiness (β=-0.17; p = 0.017), while parents of children with type 1 diabetes had disrupted sleep quality (β = 0.25; p = 0.003). Optimism was negatively associated with the evening cortisol concentration (β=-0.18; p = 0.023) and sleep quality index (β=-0.20; p = 0.012).

CONCLUSIONS

Public health programs aimed at lifestyle habit improvement, respite care, and relaxation for parents of children with chronic conditions would be useful for improving parental sleep quality, self-esteem, optimism and happiness.

Simultaneous Recording of Objective Sleep in Mothers and School-aged Children with Developmental Disabilities: A Pilot Study of Actigraphy and Videosomnography

Mothers of school-aged children ages 3 to 17 years with developmental disabilities (DDs) commonly report sleep problems in their children associated with impaired maternal sleep. However, existing research relies heavily on mothers' self-reported sleep. This study aimed to determine the feasibility of objectively measuring child and mother sleep-wake patterns using actigraphy and videosomnography. This was an observational pilot study. Mothers wore actigraphy watches and video-recorded their child's sleep for 7 nights. Mothers also completed a 7-day sleep diary and questionnaires on sleep quality, depressive symptoms, stress, and child sleep problems. Ten mothers (32-49 years) and ten children with DDs (8-12 years) completed this study. Half of the children were boys with autism spectrum disorders. We successfully recruited 77% of eligible mothers for the study during the pandemic. Eight mothers successfully wore the actigraphy, and nine successfully video-recorded their child's sleep. Mothers rated their participation positively and considered the data collection protocol acceptable. While mothers' sleep patterns from actigraphy were mostly within recommendations, self-reported sleep quality was poor. Child's sleep estimates from videosomnography showed children slept substantially less than recommended sleep hours. Mothers also reported a high frequency of child sleep problems. Consistent with this pattern, mothers also endorsed elevated stress and depression. The use of actigraphy and videosomnography is feasible. Objective sleep measurement for mothers' and children's sleep is needed with self-report to measure multidimensional aspects of sleep and discrepancies between objective and self-report sleep measures. Future studies can use multi-methods sleep measures and work toward interventions that can improve family sleep and reduce mothers' stress and depression.

Depression, anxiety, and sleep quality of caregivers of children with spinal muscular atrophy

BACKGROUND

The aim of this study was to evaluate the prevalence of anxiety, depression, sleep, and associated factors in caregivers of children with spinal muscular atrophy (SMA).

MATERIALS AND METHODS

Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory-State (STAI-S), the State-Trait Anxiety Inventory-Trait (STAI-T), and Pittsburgh Sleep Quality Index (PSQI) were used to assess the anxiety, depression, and sleep quality of the caregivers of children with SMA. Higher scores indicated worse outcome for all three questionnaires.

RESULTS

Fifty-six caregivers of children with SMA were included in the study. Median age of children was 6 (3.2-10) years and mean age of the caregivers was 37.0 ± 6.5 years. Median scores of the BDI, STAI-S, STAI-T, and PSQI were 12 (7.2-17), 35.5 (31-44), 40.5 (35-48), and 7.0 (5.0-10.0), respectively. There was a positive correlation between BDI and PSQI scores (p < 0.05). There was a negative correlation between the age of the caregivers and PSQI, BDI, STAI-T scores (p = 0.01, r = -0.341; p = 0.006, r = -0.364; p = 0.003, r = -0.395, respectively). There was a negative correlation between the age of the patients and the PSQI scores of the caregivers (p = 0.01, r = -0.33). There was a negative correlation between BDI scores and household income (p = 0.01, r = -0.34).

CONCLUSION

Caregivers of children with SMA had elevated depression and anxiety levels and they also had decreased sleep quality. Economic and social support resources are needed to help caregivers of those children.

Health and social relationships of mothers of children in special education schools

BACKGROUND AND AIMS

The number of children in special education schools has increased in Japan. This study aimed to examine the association between special education school enrollment and the health and social relationships of mothers with children in these schools using population-based samples in Japan.

METHODS AND PROCEDURES

This study used data from the Kochi Child Health Impact of Living Difficulty (K-CHILD) study in 2016. First, fifth, eighth, and eleventh-grade children in all schools in Kochi prefecture were included (n = 12,623). Associations between school type (regular or special education school) and maternal physical and mental health and social relationships were investigated by multivariate regression models.

OUTCOMES AND RESULTS

There were 134 children in special education schools (1.1 %) and 12,489 children in regular schools. Mothers of children in special education schools were more likely to have higher body mass index (BMI), poorer mental health and lower neighborhood relations score. Mothers of children in regular schools had higher BMI when their children had higher behavioral problems.

CONCLUSION AND IMPLICATIONS

Mothers of children in special education schools are at risk of obesity, poor mental health, and having fewer social networks. Services and support should be expanded for caregivers based on their child's behavioral problems and school system.

Examining factors associated with sleep quality in parents of children 4-10 years with autism spectrum disorder

PURPOSE

Parents of children with autism spectrum disorder often report poorer sleep compared to parents of typically developing children. When parents do not obtain enough quality sleep, functioning may be compromised placing the onus of care on already stressed parents. However, improving sleep duration may not improve sleep quality and is not always feasible. This study aimed to measure sleep quality in parents of children with autism spectrum disorder, determine if stress and children's sleep are associated with sleep quality and whether resources, appraisals, and coping moderate these relationships.

MATERIALS AND METHODS

Multivariable regression was used to determine the effects of stress and children's sleep problems on sleep quality and test modifying effects.

RESULTS

Mean (SD) Pittsburgh Sleep Quality Index scores was 8.81 (3.76), with 77.6% of parents scoring above the clinical cut-off. Mean (SD) Children's Sleep Habits Questionnaire scores was 54.03 (8.32), with 96.3% of parents rating their child's sleep above the clinical cut-off. Children's sleep was the only significant predictor and none of the expected effect modifiers were significant.

CONCLUSION

Children's sleep may be an important target to improve parent sleep quality but requires systematic assessment with interventional research. Implications for rehabilitationBoth parents and their 4-10-year-old children with ASD experience high levels of sleep disturbances.Clinicians can start the conversation early with parents about their children's sleep by providing them with information to increase awareness and recognize healthy sleep habits in their children.Clinicians are important in the assessment, management, and evaluation of pediatric sleep problems, which may have significant spillover effects on parents of children with ASD.There is a need for more resources and training to be available to clinicians to assess children and their parents for sleep problems, which could extend beyond the assessment of sleep and consider parent's daytime functioning and mental health.

The Caregiver Burden Inventory as a Sleep Disturbance Screening Tool for Parents of Children with Autism Spectrum Disorder

PURPOSE

The study was conducted to explore the degree to which caregiver burden is associated with sleep quality in parents of children with autism spectrum disorder, and to determine a statistically valid cutoff score for the Caregiver Burden Inventory (CBI) in order to identify parents of risk of poor sleep quality.

DESIGN AND METHODS

We conducted a cross-sectional analysis. We assessed caregiver burden with the CBI, sleep quality with the Pittsburgh Sleep Quality Index, emotional status with the Hospital Anxiety and Depression Scale, and impact on family with the Impact on Family Scale. Caregiver burden was evaluated with a logistic regression analysis. The best fit model was used in a receiver operating characteristic analysis. Likelihood ratios and post-test probabilities were calculated.

RESULTS

A total of 116 parents were included in this study. Higher caregiver burden was associated with a reduction in sleep quality in the logistic regression analysis (p < 0.001). The area under the curve for the univariate burden test model (best fit) was 76.70 (p < 0.001). The cutoff score for poor sleep quality was caregiver burden ≥26.50. The post-test probability of poor sleep quality increased to 82.02% from a pre-test probability of 76.72%.

CONCLUSIONS

Our findings suggest that caregiver burden is associated with sleep quality among parents of children with autism spectrum disorder. The findings suggest that a CBI cutoff score of 26.50 may help to detect risk of poor sleep quality in parents of children with autism spectrum disorder.

Sleep problems in children with cerebral palsy and their parents

AIM

To describe: (1) the frequency and types of sleep problems, (2) parent-rated satisfaction with their child's and their own sleep, and (3) child factors related to the occurrence of sleep problems in children with cerebral palsy (CP) and their parents. The secondary objective was to compare the sleep outcomes of children with CP with those from typically developing children and their parents.

METHOD

The Sleep section of the 24-hour activity checklist was used to assess the sleep of children with CP and their parents and the sleep of typically developing children and their parents.

RESULTS

The sleep outcomes of 90 children with CP (median age 5y, range 0-11y, 53 males, 37 females, 84.4% ambulatory) and 157 typically developing peers (median age 5y, range 0-12y; 79 males, 78 females) and their parents were collected. Children with CP were more likely to have a sleep problem than typically developing children. Non-ambulatory children with CP were more severely affected by sleep problems than ambulatory children. The parents of non-ambulatory children were less satisfied about their child's and their own sleep. Waking up during the night, pain/discomfort in bed, and daytime fatigue were more common in children with CP and more prevalent in children who were non-ambulatory.

INTERPRETATION

These findings highlight the need to integrate sleep assessment into routine paediatric health care practice. What this paper adds Children with cerebral palsy (CP) are more likely to have a sleep problem than typically developing peers. Non-ambulatory children with CP are more severely affected by sleep problems. One-third of parents of children with CP report feeling sleep-deprived often or always compared to a quarter of parents of typically developing children.

Children with cerebral palsy: A cross-sectional study of their sleep and their caregiver's sleep quality, psychological health and well-being

BACKGROUND

Children with cerebral palsy (CP) are more likely to experience sleep problems. Their sleep difficulties have been shown to be related to poorer sleep quality for their parents and caregivers. While poor sleep has been linked with poorer psychological health in other populations, few studies have focused on the potential effects of children's and caregivers' sleep disturbance on caregivers' psychological health and well-being in families of children with CP. This study investigated the association between caregivers' psychological health and well-being and their sleep quality and the sleep of their children with CP.

METHOD

Ninety-four caregivers (86% mothers; age range = 29-76 years) of children with CP aged 4 to 14 years of varying physical abilities (Gross Motor Function Classification Scale expanded and revised-level I (24), II (20), III (16), IV (10), V (24)) were recruited from a state-wide rehabilitation service. Caregivers completed the Depression, Anxiety and Stress Scale-21, Warwick-Edinburgh Mental Wellbeing Scale, Resilience Scale, Pediatric Sleep Questionnaire, Pittsburgh Sleep Quality Index, and a demographic questionnaire.

RESULTS

Sleep problems were reported for 55% of children. Poor sleep quality was reported by 71% of caregivers. While 25% of caregivers reported positive well-being and 86% reported high to very high levels of resilience, 44% reported poor psychological health. Child sleep problems were related to poorer caregiver sleep quality (r = 0.47, p < 0.001). Poorer caregiver sleep quality was related to poorer caregiver psychological health (r = 0.43-0.51, all p < 0.001) and well-being (r = -0.48, p < 0.001), but not resilience (r = 0.18, p = 0.11).

CONCLUSIONS

High numbers of children with CP and their caregivers experience poor sleep that extends far past infancy. Poor sleep quality is associated with poorer psychological health and well-being for caregivers. Further development of responsive support services that address caregivers' sleep is essential.

Potential Role of Neuroactive Tryptophan Metabolites in Central Fatigue: Establishment of the Fatigue Circuit

Central fatigue leads to reduced ability to perform mental tasks, disrupted social life, and impaired brain functions from childhood to old age. Regarding the neurochemical mechanism, neuroactive tryptophan metabolites are thought to play key roles in central fatigue. Previous studies have supported the “tryptophan-serotonin enhancement hypothesis” in which tryptophan uptake into extensive brain regions enhances serotonin production in the rat model of exercise-induced fatigue. However, serotonin was transiently released after 30 minutes of treadmill running to exhaustion, but this did not reflect the duration of fatigue. In addition, as the vast majority of tryptophan is metabolized along the kynurenine pathway, possible involvement of the tryptophan-kynurenine pathway in the mechanism of central fatigue induction has been pointed out. More recently, our study demonstrated that uptake of tryptophan and kynurenine derived from the peripheral circulation into the brain enhances kynurenic acid production in rat brain in sleep deprivation–induced central fatigue, but without change in serotonin activity. In particular, dynamic change in glial-neuronal interactive processes within the hypothalamus-hippocampal circuit causes central fatigue. Furthermore, increased tryptophan-kynurenine pathway activity in this circuit causes reduced memory function. This indicates a major potential role for the endogenous tryptophan-kynurenine pathway in central fatigue, which supports the “tryptophan-kynurenine enhancement hypothesis.” Here, we review research on the basic neuronal mechanism underlying central fatigue induced by neuroactive tryptophan metabolites. Notably, these basic findings could contribute to our understanding of latent mental problems associated with central fatigue.

Sleep in Caregivers of Children With Type 1 Diabetes

Purpose

The purpose of this study was to explore caregivers’ descriptions of their experience of nighttime sleep.

Design and Methods

Caregivers (N = 22) of children 10 to 18 years of age with type 1 diabetes (T1D) were recruited for this descriptive study. Anonymous questionnaires contained demographic information and both open- and closed-ended questions that focused on caregiving as it related to sleep. Open-ended questions were reviewed to help understand the effect of nocturnal caregiving activities on parental sleep.

Results

The sample of caregivers were all female and had a mean age of 43 years; 96% graduated high school, 68% were married or partnered, and 100% were white. Children had been diagnosed with T1D for a mean of 5 years, with a mean age of 12.2 years. Caregivers reported short sleep duration (mean, 5.8 hours). Over half of the participants reported they required ≥7 hours of sleep to feel their best, 64% indicated trouble sleeping at night, and 86% reported that caregiving interfered with their nighttime sleep, while 54% responded that sleep was “very important.” Content analysis of the open-ended questions revealed 2 themes: (1) anxiety about the child’s blood glucose levels and (2) nighttime disruptions.

Conclusions

Caregivers are frequently sleep deprived and worry about their child’s nighttime glucose. Caregiving duties, anxiety, and sleep fragmentation may contribute to their poor sleep.
