Changes in sleep duration and disturbances during Covid-19 lockdown and internalizing-externalizing behaviors in children with attention deficit hyperactivity disorders.

OBJECTIVE: To examine how changes in sleep patterns and sleep problems occurring between the pre-pandemic and the Covid-19 lockdown period influenced mood-behavioral functioning of children with Attention Deficit Hyperactivity Disorder (ADHD). METHODS: Parents of 992 children with ADHD (85.4% boys, mean age: 11.52 years, SD = 3.17), recruited from the Italian ADHD family association, completed a modified version of the Sleep Disturbance Scale for Children and filled out 11 emotional behavioral items selected from the Child Behavior Checklist (CBCL) 6-18 questionnaire. Subgroups identified based on sleep duration changes ("maintained", "increased", "reduced") and of sleep problems during lockdown ("onset", "remission", "maintained", "no sleep problem") were analyzed to evaluate the association with internalizing and externalizing scores. RESULTS: Sleep duration showed no or low influence on internalizing and externalizing behaviors after control for age, sex, and socioeconomic status. Patients with ADHD with "no sleep problem" showed significant lower scores in internalizing and externalizing behaviors than those who "maintained" or had "onset" of different sleep problems. The effect sizes were higher for internalizing than externalizing behaviors. Lower internalizing scores were found in those who remitted difficulty in falling asleep, daytime sleepiness, nightmares, vs. the "maintained" or "onset" groups and those who remitted hypnic jerks vs. the "onset" group. Children with ADHD who "maintained" sleep terrors reported higher internalizing and mainly externalizing scores than the other groups. CONCLUSION: Sleep problems negatively influence daytime functioning of patients with ADHD. but mood and behavioral domains show different susceptibility to the changes of sleep problems, and different vulnerability to specific sleep problems.

Externalizing and Internalizing Behaviors in Children with ADHD during Lockdown for COVID-19: The Role of Parental Emotions, Parenting Strategies, and Breaking Lockdown Rules.

Lockdown experience for COVID-19 pandemic significantly affected children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) exacerbating or promoting the onset of externalizing and internalizing symptoms. However, few studies have considered how externalizing and internalizing behaviors changed in relation to parental emotions and parenting strategies. In the present study, 992 caregivers of children and adolescents with ADHD from 5 to 18 years were presented with an online survey evaluating youths' externalizing and internalizing behaviors, their non-compliance with lockdown rules, and parental factors related to parental emotions and parenting strategies. Two hierarchical linear regression models were performed to examine the contribution of children's non-compliance with lockdown rules, parental emotions, and parenting strategies on children's externalizing and internalizing behaviors. Results revealed that externalizing behaviors were higher in children and adolescents with ADHD non-compliant with lockdown rules. Moreover, positive parenting strategies moderated the relationship between non-compliance with lockdown rules and externalizing behaviors. Differently, higher internalizing behaviors were observed in children with ADHD who had parents reporting more negative emotions and positive parenting strategies. In this case, parents' negative emotions had a moderator effect in the association between internalizing behaviors and non-compliance to lockdown measures. The clinical implications of these two different patterns of relations are discussed.

The impact of lockdown on sleep patterns of children and adolescents with ADHD.

STUDY OBJECTIVES: The current study examined the impact of home confinement (lockdown) because of the COVID-19 pandemic on the sleep patterns of children and adolescents with attention-deficit hyperactivity disorder (ADHD). METHODS: Nine hundred ninety-two parents of children and adolescents with ADHD filled out an anonymous online survey through the ADHD family association website. The survey investigated the sleep patterns and disturbances (using a modified version of the Sleep Disturbance Scale for Children) and screen exposure time before and during lockdown. RESULTS: During lockdown, 59.3% of children and 69.4% of adolescents with ADHD reported a change of bedtime, with a significant increase in patients with ADHD who went to sleep at 11 pm or later. Sleep duration, in contrast, resulted in 2 opposing processes with more children and adolescents sleeping either less than 6 hours/night or 10-11 hours/night. Among children and adolescents, respectively, 19.9% and 22% slept less than they did before lockdown, whereas 21.4% and 27.4% slept for more hours. Bedtime delay and decreased sleep duration were associated with an increase in screen time exposure. Moreover, patients with ADHD reported an increase in sleep disturbances when compared to their previous condition, mainly including difficulties falling asleep, anxiety at bedtime, night awakenings, nightmares, and daytime sleepiness. CONCLUSIONS: Lockdown impacted sleep-wake rhythms by strengthening the maladaptive sleep patterns reported in usual-life conditions in children and adolescents with ADHD.

Stress symptoms and Coronavirus disease 2019 (COVID-19): a comparative study between Attention Deficit Hyperactivity Disorder and typically developing children and adolescents.

BACKGROUND: Coronavirus disease 2019 (COVID-19) related confinement severely impacted people wellbeing. Many studies focused on general population, although it is reasonable to expect that patients with neurodevelopmental disorders might have been at higher risk. Children/adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) might be potentially more vulnerable, due to their intolerance to forced restrictions that limit stimulating experiences, to obligation to follow instructions and to acceptation of imposed rules We aimed to compare stress-related behavioral changes of the first COVD-19 related confinement among 6-18 years old ADHD and typically developing subjects. METHODS: Two parent-proxy online surveys have been employed, shared via social media. Symptoms of acute stress related to the pandemic and a question about family members/households' COVID-19 positivity have been listed in 8 yes/no items. Chi-squared tests were applied. RESULTS: Final sample consisted of 1078 typically developing subjects and 979 ADHD. Exaggerated startle response, difficulties in waking-up, angry mood as well as COVID-19 related fears were more prevalent among ADHD vs. typically developing subjects. typically developing subjects showed higher prevalence of research for information about COVID-19 and worries about death. CONCLUSIONS: In conclusion, the COVID-19 experience significantly impacted children and adolescents with ADHD to a great extent, similarly to typically developing subjects. ADHD showed more anxious-phobic responses, while typically developing subjects demonstrate more depressive attitudes. Differences in stress symptoms profiles between ADHD and T typically developing subjects warrant to develop distinct strategies of therapeutic interviews.
