Adapting PCIT-Health for Telehealth Delivery: A Case Study.

During the COVID-19 pandemic, children's physical health and access to mental health resources have been two critical concerns. Parent-Child Interaction Therapy-Health (PCIT-Health) is a treatment model aimed at helping parents manage children's general behavior and their behavior in obesogenic contexts (screen time and mealtime). Due to social distancing guidelines, PCIT-Health was adapted for remote delivery through video conferencing. In this article, we describe the experience of implementing virtual PCIT-Health with a family. The family's progress through treatment is described, along with the challenges associated with remote service delivery and how those challenges were addressed. Progress through treatment was measured with questionnaires administered to caregivers and with observational measures of parent-child interactions. The results from these measures indicate that caregivers experienced a reduction in stress and improvements in their child's behavior after PCIT-Health completion. They also reported engaging in healthier management of their child's screen time and mealtime behaviors. As coded from observational assessments, parents increased their use of positive parenting practices. Telehealth-delivered PCIT-Health is a promising treatment modality for increasing parenting skills and improving child behavior.

Qualitative changes in children's physical activity and sedentary behaviours throughout the COVID-19 pandemic: The HomeSPACE project.

Opportunities for children to be physically active during the COVID-19 pandemic were limited, resulting in a decrease in overall physical activity and an increase in sedentary behaviour during the lockdown restrictions of the pandemic. This study further explored these changes across various stages of the restrictions, starting during the first UK-wide lockdown in March 2020 through to the "new normal" in December 2021. Nine families, consisting of eleven children (36% girls, 64% boys; aged 13.38 years ± 1.14), eight mothers and one father were tracked throughout this time, using semi-structured interviews to explore the fluctuations in physical activity and sedentary behaviour in the home environment in the context of self-determination theory. Findings indicate that as restrictions eased, physical activity within the home decreased, as children were exposed to more opportunities at school and in the community; these opportunities seemingly increased children's motivation to be physically active through increasing levels of their basic psychological needs of autonomy, competence, and relatedness. Some children's physical activity levels have returned to pre-COVID-19 levels, with a newfound enjoyment for being physically active. Whilst others now prefer to pursue more sedentary behaviours that became habitual during the lockdown restrictions. Accessible opportunities now need to be promoted to drive up children's motivations to be physically active following the years of uncertainty around the COVID-19 pandemic.

Associations between parenting stress, parent feeding practices, and perceptions of child eating behaviors during the COVID-19 pandemic.

The aim of this study was to explore associations between parenting stress, feeding practices, and perceptions of children's eating behaviors during the COVID-19 pandemic. Parents (n = 284) of children ages 4-6 years completed a cross-sectional online survey during the onset of pandemic-related stay-at-home mandates in the U.S. Parents reported current levels of parenting stress, feeding practices, and child eating behaviors. Parents also reported whether parenting stress had increased, stayed the same, or decreased since prior to the onset of pandemic-related stay-at-home mandates. Greater levels of parenting stress were associated with less desirable feeding practices, including greater odds of high use of food for emotional regulation (OR = 1.05, 95% CI = 1.03-1.08), food as a reward (OR = 1.05, 95% CI = 1.02-1.08), and pressure to eat (OR = 1.03, 95% CI = 1.01-1.06), and low use of encouraging a balanced diet (OR = 1.03, 95% CI = 1.01-1.06). Greater levels of parenting stress were also associated with greater perceptions that children exhibited problematic eating behaviors, including greater odds of high food fussiness (OR = 1.05, 95% CI = 1.02-1.08) and low enjoyment of food (OR = 1.05, 95% CI = 1.02-1.07). For parents who reported their parenting stress had increased, greater parenting stress was associated with more frequent use of pressure to eat (p = .009) and less frequent monitoring their child's diet (p = .028). In conclusion, parenting stress during the pandemic was associated with use of food for emotional and behavioral regulation and perceptions that children exhibited problematic eating behaviors. Further research is needed to understand how to mitigate parenting stress and promote healthy feeding practices during times of crisis.

Behavioral, Affective, and Cognitive Parenting Mechanisms of Child Internalizing and Externalizing Problems during the COVID-19 Pandemic.

The COVID-19 pandemic has led to increased mental health concerns, including depression and anxiety among parents and internalizing and externalizing problems among youth. To better understand the mechanisms and moderators of child mental health during the pandemic, the current study tested two moderated mediation models in which parent depression and anxiety indirectly impacted child internalizing and externalizing problems through negative effects on multiple parenting variables, with these associations moderated by families' exposure to COVID-19-stressors. A national sample representative of U.S. parents (N = 796, 48.2% female, Mage = 38.87 years, 60.3% Non-Hispanic white, 18.1% Hispanic/Latinx, 13.2% Non-Hispanic Black/African-American, 5.7% Asian, 2.8% Other Race) completed a cross-sectional online survey in February-April 2021. Children ranged from 5-16 years old (Mage = 10.35 years, 59.8% Non-Hispanic white, 17.2% Hispanic/Latinx, 13.7% Non-Hispanic Black/African-American, 4.5% Asian, 4.8% Other Race). Parent depression/anxiety was directly and indirectly associated with child internalizing and externalizing problems. For both internalizing and externalizing problems, indirect associations occurred by means of increased parent hostility and inconsistent discipline and decreased routines and parent supportiveness. There were also specific indirect effects through decreased monitoring (internalizing problems) and parenting self-efficacy (externalizing problems). Multiple indirect effects were moderated by number of COVID-19-stressors experienced. Notably, COVID-19-stressors did not have direct effects on child mental health when other variables were considered. Findings highlight the buffering effects of parents for child mental health, the need to address parent depression/anxiety in child interventions, the utility of existing evidence-based parent interventions during the pandemic, and the need to assess families' level of exposure to COVID-19-stressors.

Associations between parent-child relationship, and children's externalizing and internalizing symptoms, and lifestyle behaviors in China during the COVID-19 epidemic.

To investigate associations between parent-child relationships, children's externalizing and internalizing symptoms, and lifestyle responses to the COVID-19 epidemic, we conducted an online survey of a random, representative sample of residents with children aged 3-17 years during mid-March 2020 in Wuhan and Shanghai, China. A total of 1655 parents and children were surveyed with a response rate of 80.1% in the survey. During the epidemic, the frequency of children enquiring about the epidemic (AOR = 1.46, 95% CI: 1.04, 2.06), parents explaining the epidemic to them (AOR = 2.87, 95% CI: 1.80, 4.58), parents expressing negative emotions in front of them (AOR = 2.62; 95% CI = 2.08-3.30), and parents with more irritable attitudes (AOR = 1.93; 95% CI = 1.33-2.81) were significantly associated with children's externalizing symptoms. For internalizing symptoms, significant associations were found with worse parent-child closeness (AOR = 2.93; 95% CI = 1.80-4.79), the frequency of parents expressing negative emotions in front of them (AOR = 2.64; 95% CI = 1.68, 4.12), and more irritable attitudes (AOR = 2.24; 95% CI = 1.42-3.55). We also found that each indicator of parent-child relationships had the significantly similar associations with children's lifestyle behaviors. These findings suggest that improving parents' attitudes towards their children and parent-child closeness during the epidemic, especially among parents with lower educational levels, are important to ensure the wellbeing of children.

An mCARE study on patterns of risk and resilience for children with ASD in Bangladesh.

Community-wide lockdowns in response to COVID-19 influenced many families, but the developmental cascade for children with autism spectrum disorder (ASD) may be especially detrimental. Our objective was to evaluate behavioral patterns of risk and resilience for children with ASD across parent-report assessments before (from November 2019 to February 2020), during (March 2020 to May 2020), and after (June 2020 to November 2020) an extended COVID-19 lockdown. In 2020, our study Mobile-based care for children with ASD using remote experience sampling method (mCARE) was inactive data collection before COVID-19 emerged as a health crisis in Bangladesh. Here we deployed "Cohort Studies", where we had in total 300 children with ASD (150 test group and 150 control group) to collect behavioral data. Our data collection continued through an extended COVID-19 lockdown and captured parent reports of 30 different behavioral parameters (e.g., self-injurious behaviors, aggression, sleep problems, daily living skills, and communication) across 150 children with ASD (test group). Based on the children's condition, 4-6 behavioral parameters were assessed through the study. A total of 56,290 behavioral data points was collected (an average of 152.19 per week) from parent cell phones using the mCARE platform. Children and their families were exposed to an extended COVID-19 lockdown. The main outcomes used for this study were generated from parent reports child behaviors within the mCARE platform. Behaviors included of child social skills, communication use, problematic behaviors, sensory sensitivities, daily living, and play. COVID-19 lockdowns for children with autism and their families are not universally negative but supports in the areas of "Problematic Behavior" could serve to mitigate future risk.

Child Maltreatment During the COVID-19 Pandemic: A Systematic Rapid Review.

The present study is systematic rapid review on the nature of the relationship between the COVID-19 pandemic and child maltreatment. Database searches on December 28, 2020, identified 234 unique citations; 12 were ultimately included in our analysis. Included articles measured child maltreatment inclusive of physical, psychological, and sexual abuse, and child neglect during the COVID-19 pandemic. Compared with the prepandemic period, 5 articles found an increase in child maltreatment, 6 articles found a decrease, and 1 study found no difference. There existed variation in geography of study location, age of child maltreatment victims, and types of child maltreatment assessed.

Child Psychological Functioning During the COVID-19 Lockdown: An Ecological, Family-Centered Approach.

OBJECTIVE: To evaluate how sociodemographic characteristics and various aspects of parent well-being, family functioning, parent-child relationship, and child characteristics are related to psychological functioning in children aged 9 to 12 years during the COVID-19 lockdown. METHOD: Participants included 144 children aged 9 to 12 years and their parents who lived in the province of Quebec, Canada, during the COVID-19 mandatory lockdown. Parents and children were administered a phone-based survey in which various child, parent, parent-child, and family characteristics were assessed. RESULTS: Results showed that higher internalizing problems in children were related to greater depressive symptoms in parents, lower attachment security to parents, and greater aversion to aloneness in children. Results on externalizing behavior problems showed that more problems were associated with more family dysfunction and chaos and lower attachment security to parents. Finally, results on children's anxiety toward COVID-19 showed that more anxiety was associated with greater parental anxiety toward COVID-19 and more child aversion to aloneness. CONCLUSION: Our findings showed that even during an unusual and stressful context such as a pandemic, proximal variables such as the attachment relationship that have been known to be closely associated with adaptation are significantly related to child psychological functioning. Such observations are important because they highlight factors that may accentuate child vulnerability in times of a pandemic and shed light on potential intervention targets.

Context matters for preschool discipline: Effects of distance learning and pandemic fears.

The COVID-19 pandemic transformed the context and delivery of early childhood education, yet little is known about its impact on exclusionary discipline (e.g., suspension, expulsion), which nationally representative evidence has shown disproportionately impacts Black boys. Using one experiment, we test how preschool providers respond to three hypothetical vignettes about a Black boy's behaviors. Participants (N = 60) were randomly assigned to read vignettes set in either distance learning or in-person classroom contexts. Then, participants completed measures about discipline and COVID-19. Results indicated there was an interaction between context and the sequence of vignettes on providers' troubled feelings and endorsements of discipline. Providers showed heightened troubled feelings and endorsements of discipline severity in the distance learning context, as compared to an in-person context, as vignettes progressed. Additionally, the more providers feared COVID-19, the more they felt troubled over the course of the vignettes across conditions. Practitioners can use this research to inform consultative interventions that mitigate discipline by directly addressing providers' pandemic fears and classroom contexts.

Social and psychological effects of the COVID-19 pandemic on middle-school students: Attendance options and changes over time.

The purpose of this study was to determine whether restrictions put in place during the COVID-19 pandemic affected the social and psychological well-being of early adolescent schoolchildren. Participants were 309 youth (51% female, average age = 12.38 years) enrolled in the sixth, seventh, or eighth grades of a single middle school located in northeastern Pennsylvania, a state that took a moderately proactive approach to the pandemic. Employing a cross-sectional design, students in three instructional conditions (100% in-person, hybrid, 100% online) were compared on nine outcome measures (perceived parental support, perceived parental knowledge, peer deviance, neutralization, cognitive impulsivity, depression, delinquency, bullying victimization, and bullying perpetration). There were no significant between-groups differences, although there was a borderline significant effect for depression (100% online > 100% in-person, p = .06). A second set of analyses employed a longitudinal design and compared 174 children who completed the test battery in November 2019, 3 months before the start of the pandemic, and then again in November 2020, 9 months after the start of the pandemic. Three out of nine outcomes displayed significant change: A small reduction in parental support and modest increments in neutralization beliefs and cognitive impulsivity. Although there were no statistically significant differences between the three instructional conditions and only a handful of relatively small and predictable longitudinal changes between November 2019 and November 2020, there were a fair number of individual students who experienced moderate (≥ 50%) increases in depression (17.6%), cognitive impulsivity (15.8%), and bullying victimization (11.7%).

Effects of Covid-19 confinement on the mental health of children and adolescents in Spain.

In Spain, in order to control COVID-19 transmission, one of the strictest confinement measures in the world for children and teenagers has been implemented. From 14 March to 26 April 2020 underage Spaniards were not allowed to leave their homes, except for reasons of force majeure. This could have consequences on their mental health in both the short and the long term. Thus, the aim of the present study was to explore the consequences of confinement on the mental health of Spanish children and teenagers, at the time when minors had been locked down in their homes between 8 and 10 days. The sample was composed of 590 confined Spanish children and teenagers between 8 and 18 years old. The scales of Depression, Self-esteem, Anxiety, Problems with Emotional Regulation, Rage Control Problems, Integration and Social Competence, Somatic Complaints, Rebellious Behaviour, as well as Awareness of the Problems of the Assessment System for Children and Adolescents (SENA) were used. The results revealed that, during confinement, children and adolescents showed emotional and behavioural alterations. This study, as far as we know, is the first one to explore the psychological consequences of lockdown in minors while it was taking place, with them being the ones directly assessed.

Psychological impact of COVID-19 lockdown in children and adolescents from San Carlos de Bariloche, Argentina: Parents' perspective. / Impacto psicológico del aislamiento por COVID-19 en jóvenes de San Carlos de Bariloche, Argentina: la mirada de los padres.

INTRODUCTION: From an infectious perspective, children and adolescents were not highly affected by the COVID-19 pandemic. However, social isolation measures have deeply changed their lifestyle, which is believed to have a psychological impact on them. The objective was to assess the impact of COVID-19 lockdown on the emotional health of children and adolescents attending primary or secondary school. POPULATION AND METHODS: Parents of children and adolescents from San Carlos de Bariloche participated in the study. Adults' perception of the emotional and behavioral impact of lockdown on children and adolescents, changes in sleeping habits, screen use, sports-related activities, eating, and medical consultations, was assessed. RESULTS: A total of 267 parents were included. Of them, 96.3 % noticed emotional and behavioral changes. The most common ones were that their children were more bored (76.8 %), more irritable (59.2 %), more reluctant (56.9 %), and angrier (54.7 %). It was observed that they woke up and went to bed later, and slept 30 minutes more. Moreover, leisure screen use increased by 3 hours on weekdays. Time dedicated to physical activities did not change, but the type of activities did: swimming and team sports were replaced by biking, walking, and skiing. CONCLUSIONS: COVID-19 lockdown affected the emotional health and habits of children and adolescents. Boredom, irritability, and reluctance were more present during lockdown. The possibility of doing outdoor physical activities allowed them to keep practicing sports.

Resultados. Se incluyeron 267 padres. El 96,3 % observó cambios emocionales y de comportamiento. Los más frecuentes fueron que estaban más aburridos (el 76,8 %), irritables (el 59,2 %), desganados (el 56,9 %) y enojados (el 54,7 %). Se observó que se levantaban y acostaban más tarde y dormían 30 minutos más. Además, el uso de pantallas por esparcimiento aumentó 3 horas durante los días hábiles. El tiempo dedicado a la actividad física no varió, pero sí cambió el tipo de actividades: la natación y los deportes de equipo fueron reemplazados por ciclismo, caminatas y esquí. Conclusiones. El aislamiento por COVID-19 impactó sobre la salud emocional y los hábitos de los jóvenes. El aburrimiento, la irritabilidad y el desgano estuvieron más presentes durante el aislamiento. La posibilidad de realizar actividades al aire libre permitió que continuaran practicando deportes.

Support for Families During COVID-19 in Spain: The iCygnus Online Tool for Parents.

On March 14, 2020 one of the strictest confinements in Europe was imposed on the citizens of Spain. The online tool for parents, iCygnus, was designed to reduce the psychological impact generated by the pandemic on the child population (2-12 years of age) through automatic recommendations to parents based on individual responses about their parenting styles and their child's characteristics. The profiles of the 710 families indicate a higher prevalence of internalizing and externalizing behavior problems in children, as well as a relationship between punitive parenting in families where the parents lost their jobs due to the coronavirus disease (COVID-19). The usefulness of the help offered by iCygnus was evaluated after 6 weeks, and almost 80% of the families indicated that they used the recommendations and that they helped them in their relationship with their children.

Impact of the COVID-19 Outbreak on the Behavior of Families in Italy: A Focus on Children and Adolescents.

The COVID-19 pandemic has changed individuals' lifestyles to a great extent, particularly in Italy. Although many concerns about it have been highlighted, its impact on children and adolescents has scarcely been examined. The purpose of this study was to explore behavioral consequences and coping strategies related to the pandemic among families in Italy, by focusing on developmental ages from the caregivers' perspective, 3 weeks into quarantine. An exploratory cross-sectional online survey was conducted over 14 days. Google Forms was employed to conduct the survey. Demographic variables and pre-existing Psychological Weaknesses (PsW) were asked. Adults' sleep difficulties (SleepScore) and coping strategies during quarantine were assessed. Behavioral changes related to quarantine of both subjects completing the form (COVIDStress) and their children (when present) were questioned. Of the 6,871 respondents, we selected 6,800 valid questionnaires; 3,245 declared children aged under 18 years of age (caregivers). PsWs were recognizable in 64.9% among non-caregivers and in 61.5% of caregivers, with a mean PsW score of 1.42 ± 1.26 and 1.30 ± 1.25 over 3 points, respectively. The 95.5% of the non-caregivers and the 96.5% of caregivers presented behavioral changes with a mean COVIDStress of 3.85 ± 1.82 and 4.09 ± 1.79 over 8, respectively (p<0.001). Sleep difficulties were present in the 61.6% of the non-caregivers and in the 64.4% of the caregivers (p < 0.001), who showed higher SleepScores (2.41 ± 1.26 against 2.57 ± 1.38 points over 6, p < 0.001). COVIDStress (and SleepScore) strongly correlated with PsW (p < 0.001). Caregivers observed behavioral changes in their children in the 64.3% of the <6 years old and in 72.5% of 6-18 years old. Caregivers' discomfort related to quarantine (COVIDStress, SleepScore) was strongly associated to behavioral changes in both age groups of <6 and 6-18 (p < 0.001). Presence of caregivers' coping strategies was less associated to behavioral changes in the <6 sample (p = 0.001) but not in the 6-18 (p = 0.06). The COVID-19 pandemic has adversely impacted families in Italy with regard to behavioral changes, especially in high-risk categories with PsWs and caregivers, especially the ones with children aged <6 years. While coping strategies functioned as protective factors, a wide array of stress symptoms had implications for children's and adolescents' behaviors. It is recommended that public children welfare strategies be implemented, especially for higher-psychosocial-risk categories.

Parental worry, family-based disaster education and children's internalizing and externalizing problems during the COVID-19 pandemic.

Objective: Internalizing and externalizing problems are prevalent in disaster-exposed children but few studies have investigated these problems in relation to parental factors. This study examined how parental worry and family-based disaster education related to children's internalizing and externalizing problems during the outbreak of COVID-19 in China. Method: Parents reported parental worry, family-based disaster education and their children's (5-8-year-old young elementary schoolchildren [n = 245] and 245 9-13-year-old early adolescents [n = 245]) internalizing and externalizing problems. Results: Data analysis showed that (a) across ages, parental worry related to children's internalizing and externalizing problems significantly and positively; (b) the significant and negative relationships between family-based disaster education and internalizing and externalizing problems were only supported in young elementary schoolchildren; and (c) high level of parent worry attenuated the negative link between family-based disaster education and young elementary schoolchildren's internalizing problems. Conclusion: This study expands our knowledge about relationships between parental worry and children's disaster-related well-being, and highlights the importance of adapting family-based disaster education to different ages. Data suggest that parents of young elementary schoolchildren and early adolescents both should avoid showing excessive worry in front of their children during the pandemic to help reduce their children's internalizing and externalizing problems. Effective family-based disaster education can mitigate young elementary schoolchildren's emotional distress and behavioral problems, the effect of which may be maximized if parents can avoid being overly worried. Parents of early adolescents should support their children in acquiring pandemic-related information independently and encourage them to seek support outside the family.

School closure during the coronavirus disease 2019 (COVID-19) pandemic - Impact on children's sleep.

OBJECTIVE: To evaluate the sleep habits of school-going children before and during school closure in the national lockdown period (called 'Circuit Breaker' or CB in Singapore) due to the COVID-19 pandemic. METHODS: Cross-sectional, anonymous, online, population-based survey questionnaire was administered to parents aged 21 years and above with children aged between 3 and 16 years attending pre-school, primary or secondary school (equivalent to kindergarten, middle and-high school) and residing in Singapore. Sleep duration in relation to various daily activities including academic activities, physical exercise, and screen time was evaluated pre-CB and during CB. RESULTS: Data from 593 participants were analyzed. Pre-CB, the overall mean (SD) sleep duration of the study population was 9.01 (1.18) hours on weekdays and 9.99 (0.94) hours on weekends. During CB, mean (SD) sleep duration overall was 9.63 (1.18) hours. Although children generally went to bed later (mean 0.65 h later), they woke up even later during CB (mean 1.27 h later), resulting in longer sleep duration (mean increase of 0.35 h). This was most evident in secondary school children (mean increase of 0.70 h). Children attending private schools (which had later start times) had increased sleep duration (mean 10.01 (SD 0.89) hours pre-CB and 10.05 (SD 0.93) hours during CB) compared to public schools (mean 9.05 (SD 0.91) pre-CB and 9.49 (SD 1.22) hours during CB). CONCLUSIONS: School closure from the COVID-19 pandemic resulted in longer sleep duration in school-going children. Early school/academic activity start times had a significant impact on limiting children's sleep duration.

Implications of COVID-19-induced nationwide lockdown on children's behaviour in Punjab, India.

BACKGROUND: Lockdown is one of the prevalent tools that are used to control the spread of COVID-19 virus in India. Under the circumstances created during lockdown period, children are deprived from the social interaction and companionship; because of which, they are susceptible to psychiatric disorders. Therefore, in this study, efforts were to understand the impacts of lockdown on the mental status of the children of India and their specific causes. STUDY DESIGN: It is a questionnaire-based study. METHODS: A web-based questionnaire was prepared, and 400 parents from four districts of Punjab, India, namely, Ludhiana, Sahibzada Ajit Singh (SAS) Nagar, Sangrur and Ferozepur, were telephonically interviewed. Further, the information collected from the interviews was statistically analysed using Statistical Package for the Social Sciences (SPSS) software. RESULTS: Findings from this study revealed that 73.15% and 51.25% of the children were having signs of increased irritation and anger, respectively; 18.7% and 17.6% of the parents also mentioned the symptoms of depression and anxiety, respectively, among their children, which were also augmented by the changes in their diet, sleep, weight and more usage of the electronic equipment. Children (~76.3%) persistently urge to go outdoors and play with their friends; therefore, they could lag in social development. Further, observations from Pearson's correlation revealed that during lockdown, children's mental health is significantly related to the area of their house, number of children in the family, qualification of their mother and socio-economic status of their family. CONCLUSIONS: This study made it evident that the mental health of the children residing in Punjab, India, was compromised during the lockdown period induced by the COVID-19 pandemic. Findings of this study may also trigger the international authorities to frame the guidelines of lockdown in the interest of mental health of their native children.
