<p>The implementation of social distancing measures (e.g., school closures) by governments worldwide to prevent the spread of COVID-19 has affected millions of children and their families. However, the consequences of such measures on the wellbeing of children with special educational needs (SEN) and their caregivers are not fully understood. The present study examined the socioemotional wellbeing and daily habits of children between 5 and 12 years old with SEN during the first national COVID-19 lockdown in the United Kingdom. Participants were 995 caregivers between 18 and 61 years old living in the United Kingdom who completed a 20 -min electronic survey on child and family wellbeing distributed via social networks between July and August 2020. The findings showed that children with SEN were more likely to experience more emotional and behavioral difficulties during the lockdown than children without SEN. Children with SEN but without mental health difficulties did not have more behavior difficulties during the lockdown than children without SEN. There was a significant increase in screen time and decrease in sleep time for children with and without SEN during the lockdown, but children with SEN were using screens more often than children without SEN both before and during the lockdown. Finally, caregivers with children with SEN reported more difficulty with the confinement than caregivers with children without SEN, but caregiver and child poor mental health were likely to explain the difference. The findings show that the wellbeing of children with SEN was more likely to be negatively affected by the lockdown than the wellbeing of children without SEN. Caregiver and child mental health were likely to explain the differences.</p>

<title>Introduction</title>
<p>The coronavirus disease-2019 (COVID-19) pandemic has had an unprecedented impact on children and families across the world. To cope with the rapid spread of the disease, governments worldwide implemented wide-ranging public health measures including lockdowns and school closures. The United Kingdom (UK) has been one of the seriously affected countries, which led the government to implement the first national lockdown in March 2020 to slow the spread of the coronavirus (<xref ref-type="bibr" rid="B78">Worldometer, 2020</xref>). The lockdown resulted in school closures for all children except for vulnerable children and children of keyworkers. School closures resulted in extensive disruption to the psychological, academic, and social lives of children and young people (<xref ref-type="bibr" rid="B24">Holmes et al., 2020</xref>; <xref ref-type="bibr" rid="B16">Creswell et al., 2021</xref>; <xref ref-type="bibr" rid="B54">Panchal et al., 2021</xref>). Additionally, because education, mental health, and social care service provision were rapidly withdrawn (<xref ref-type="bibr" rid="B44">National Autistic Society, 2020</xref>), many children with special educational needs and disabilities (SEND) and their families were left without access to their usual support (<xref ref-type="bibr" rid="B14">Coughlan, 2020</xref>; <xref ref-type="bibr" rid="B47">O&#x2019;Connor et al., 2020</xref>; <xref ref-type="bibr" rid="B56">Pearcey et al., 2020</xref>; <xref ref-type="bibr" rid="B4">Asbury et al., 2021</xref>; <xref ref-type="bibr" rid="B20">Family Fund, 2021</xref>).</p>
<p>Research based on parental reports has suggested that many children with SEND experienced a decline in their mental health and wellbeing during the pandemic (<xref ref-type="bibr" rid="B1">Alghrani and Byrne, 2020</xref>; <xref ref-type="bibr" rid="B19">Disabled Children&#x2019;s Partnership, 2020</xref>; <xref ref-type="bibr" rid="B4">Asbury et al., 2021</xref>; <xref ref-type="bibr" rid="B15">Council for Disabled Children, 2021</xref>; <xref ref-type="bibr" rid="B20">Family Fund, 2021</xref>; <xref ref-type="bibr" rid="B44">National Autistic Society, 2020</xref>). According to the findings from the Co-SPACE study, as the first lockdown progressed over a 1-month period, children and adolescents with special educational needs (SEN) and neurodevelopmental disorders (ND) had markedly increased emotional difficulties, conduct problems, and hyperactivity/inattention compared to those without SEN/ND (<xref ref-type="bibr" rid="B13">CO-SPACE, 2021</xref>; <xref ref-type="bibr" rid="B74">Waite et al., 2021</xref>). Moreover, the COVID-19 pandemic has impacted the mental health of families with children with SEND disproportionally. Increases in mental health difficulties could be due to the already higher prevalence of mental health conditions in children with SEND (<xref ref-type="bibr" rid="B62">Simonoff et al., 2008</xref>; <xref ref-type="bibr" rid="B45">Neil et al., 2016</xref>; <xref ref-type="bibr" rid="B7">Cai et al., 2018</xref>; <xref ref-type="bibr" rid="B17">Dehghan et al., 2020</xref>; <xref ref-type="bibr" rid="B58">Predescu et al., 2020</xref>) and their parents (<xref ref-type="bibr" rid="B4">Asbury et al., 2021</xref>). However, another body of growing research suggests that not all families and children with SEND experienced the effects of the pandemic in the same way. Research by the <xref ref-type="bibr" rid="B15">Council for Disabled Children (2021)</xref> in England found that restrictions helped some children and young people stay mentally healthy as they enjoyed home-schooling and a slower pace of life. Likewise, the Co-SPACE study demonstrated that children and adolescents with SEN/ND scored lower on conduct problems, hyperactivity/inattention, and emotional symptoms compared to children without SEN/ND who had increased scores across these symptoms during the lockdown (<xref ref-type="bibr" rid="B74">Waite et al., 2021</xref>). This was an intriguing finding as it suggested that children with and without SEND have been affected differently by the pandemic; thus, generalizations about the impact of COVID-19 on their wellbeing should be avoided. Further research is required to fully understand the effects of the pandemic on the socioemotional wellbeing of children with SEND.</p>
<p>It has been widely agreed that, generally, the pandemic disrupted the routine of children with SEND including healthy daily habits such as a balanced diet and screen use, and adequate physical exercise and sleep (<xref ref-type="bibr" rid="B22">Geraghty and Lyons, 2021</xref>). It has been suggested that these disruptions had had a negative impact on the wellbeing of children with SEND, because they thrive on predictable routines and consistent schedules (<xref ref-type="bibr" rid="B43">Narzisi, 2020</xref>; <xref ref-type="bibr" rid="B69">Toseeb et al., 2020</xref>). For instance, a study of a small sample of Spanish children with SEND (<italic>n</italic> = 38) aged between 2 and 12 years old found that most children were overusing technology and screens (81.5%), engaging in little physical exercise (57.9%), and were eating more (86.9%) than usual during the lockdown (<xref ref-type="bibr" rid="B5">Berasategi Sancho et al., 2021</xref>). Another study of a sample of Canadian children (mean age: 11.7) found that while children with an autistic spectrum disorder (ASD) used screens as much as children in a community sample during the lockdown, there was a significantly steeper increase in change in screen use time with age for the community sample compared to the ASD sample (<xref ref-type="bibr" rid="B8">Cardy et al., 2021</xref>). These mixed findings highlight the need for more research to help understand the impact of the lockdown on the daily habits of children with SEND and in relation to children with no SEND.</p>
<p>In addition to the changes in socioemotional wellbeing and daily habits of children, the lockdown interfered with family life. Families who are raising children with SEND face more stressors than those with children without SEND (<xref ref-type="bibr" rid="B36">McStay et al., 2014</xref>; <xref ref-type="bibr" rid="B34">McConnell and Savage, 2015</xref>). Such stressors can, in turn, influence the quality of family relationships, making patient and empathic parenting challenging at times (<xref ref-type="bibr" rid="B51">Osborne et al., 2008</xref>). Families in several European countries (Italy, Spain, and Belgium; <xref ref-type="bibr" rid="B50">Orgil&#x00E9;s et al., 2020</xref>; <xref ref-type="bibr" rid="B65">Stassart et al., 2021</xref>) and the United Kingdom (<xref ref-type="bibr" rid="B41">Morg&#x00FC;l et al., 2020</xref>) reported difficulties with family co-existence during the home confinement. In the United Kingdom, families who found co-existence difficult were more likely to report that their children&#x2019;s behavior and emotional state had changed for the worse since the lockdown had started (<xref ref-type="bibr" rid="B41">Morg&#x00FC;l et al., 2020</xref>). To the best of our knowledge, no study has investigated how families with SEND children coped with family co-existence during the lockdown compared to children without SEND.</p>
<p>The lockdown might have affected children with SEND and their families disproportionately compared to children with no SEND with negative implications for their mental health and wellbeing (<xref ref-type="bibr" rid="B69">Toseeb et al., 2020</xref>; <xref ref-type="bibr" rid="B4">Asbury et al., 2021</xref>). Despite these negative effects, research is primarily focused on the general child population mostly including neurotypical children (<xref ref-type="bibr" rid="B67">Su et al., 2021</xref>). Additionally, emerging research suggests that children with SEND have been impacted differentially in terms of their social and emotional outcomes and daily routines, with some children having experienced poorer wellbeing and adopted poorer habits while for others old habits and wellbeing did not change significantly. Furthermore, the studies vary significantly in terms of sample size, measurement, conceptualization of daily habits, and cultural context, making the interpretation of findings challenging. Finally, more research on how caregivers of children with SEND experienced the confinement and its consequences is required. Therefore, the aim of this study was to examine changes before and during the lockdown in a range of social and emotional wellbeing outcomes and in daily habits, and family co-existence difficulty in children with SEN and in relation with children with no SEN in a large sample of children living in the United Kingdom during the first national lockdown.</p>

<title>Participants and Procedures</title>
<p>Caregivers living in the United Kingdom were invited to complete an electronic survey on child and family wellbeing between July and August 2020. The survey was distributed via social networks (e.g., Facebook, Instagram), e-mail, and messaging groups (e.g., WhatsApp). The caregivers were asked to provide sociodemographic information and complete a set of questionnaires about their own mental health and wellbeing, parenting stress, response to COVID-19 lockdown, and about their perception of the impact of the lockdown on their child&#x2019;s psychological wellbeing and daily habits, and of the child&#x2019;s mental health and wellbeing. Children did not participate in the survey. Survey development details have been described in <xref ref-type="bibr" rid="B41">Morg&#x00FC;l et al. (2020)</xref>. The study was approved by the University of Roehampton Research Ethics Committee (PSYC 20/367). The total number of participants were 995 caregivers between 18 and 61 years old (<italic>M</italic><sub><italic>age</italic></sub> = 39.16 years, <italic>SD</italic> = 5.62). Nearly one in six caregivers reported that their children received support for special educational needs (SEN) (<italic>n<sub><italic>SEN</italic></sub></italic> = 169, 17.0%; <italic>n<sub><italic>non&#x2013;SEN</italic></sub></italic> = 826, 83.0%). The percentage of all pupils in England with SEN support in 2020/21 was 12.2% (<xref ref-type="bibr" rid="B48">Office for National Statistics, 2021</xref>). Therefore, the sample had a higher proportion of children receiving SEN support than the school population in England. Participant characteristics by SEN support are presented in <xref ref-type="table" rid="T1">Table 1</xref>. Caregivers were mostly of White ethnic background (94.1%<italic><sub><italic>SEN</italic></sub></italic>, 91.4%<italic><sub><italic>non&#x2013;SEN</italic></sub></italic>). Across both samples most caregivers were married (<italic>n<sub><italic>SEN</italic></sub></italic> = 105, 62.1%; <italic>n<sub><italic>non&#x2013;SEN</italic></sub></italic> = 633, 76.6%), in employment (<italic>n<sub><italic>SEN</italic></sub></italic> = 105, 78.9%; <italic>n<sub><italic>non&#x2013;SEN</italic></sub></italic> = 619, 85.4%) and had at least a university degree (<italic>n<sub><italic>SEN</italic></sub></italic> = 103, 63.2%; <italic>n<sub><italic>non&#x2013;SEN</italic></sub></italic> = 657, 80.2%). Children were (<italic>n<sub><italic>boys</italic>&#x2013;<italic>SEN</italic></sub></italic> = 106, 63.1%; <italic>n<sub><italic>boys</italic>&#x2013;non&#x2013;_<italic>SEN</italic></sub></italic> = 440, 53.5%) between 5 and 12 years old (<italic>M</italic><sub><italic>age_SEN</italic></sub> = 8.28 years; <italic>SD</italic> = 2.1; <italic>M<sub><italic>age_non&#x2013;SEN</italic></sub></italic> = 7.32 years, <italic>SD</italic> = 2.0).</p>

The SDQ is a psychometrically strong parent-reported questionnaire used internationally to screen for poor mental health and wellbeing in children (<xref ref-type="bibr" rid="B66">Stone et al., 2010</xref>). Caregivers are asked to indicate whether the child exhibits a range of emotional and behavioral difficulties on a three-point scale (0 = <italic>not true</italic>&#x2014;2 = <italic>certainly true</italic>). The items can be divided between five subscales of five items each (emotional symptoms, conduct problems, hyperactivity, peer problems, and pro-social behavior). Example items include &#x201C;<italic>Considerate of other people&#x2019;s feelings</italic>,&#x201D; &#x201C;<italic>Restless, overactive, cannot stay still for long</italic>,&#x201D; &#x201C;<italic>Often has temper tantrums or hot tempers.</italic>&#x201D; A total difficulty score (range: 0&#x2013;40) was generated by adding all the subscales, except for the pro-social behavior.

<p>The K6 (<xref ref-type="bibr" rid="B28">Kessler et al., 2002</xref>) was used to examine caregivers&#x2019; psychological wellbeing. The K6 assesses the frequency of psychological distress over a period of 30 days prior to administration. It includes six items rated on a 5-point scale (1 = <italic>all of the time</italic> - 5 = <italic>none of the time)</italic>. Example items include &#x201C;<italic>How often did you feel nervous?</italic>&#x201D; and &#x201C;<italic>How often did you feel hopeless?</italic>&#x201D; Positive valence items were reverse coded. A total score of psychological distress (range: 6&#x2013;30) was generated by adding all the items. Higher scores reflect higher levels of psychological distress (<xref ref-type="bibr" rid="B29">Kessler et al., 2003</xref>).

It comprises four subscales that examine parenting stressors (6 items), loss of control (3 items), satisfaction (3 items), and rewards (6 items) rated on a 5-point scale (1 = <italic>strongly disagree</italic>&#x2014;5 = <italic>strongly agree).</italic> Example items include &#x201C;<italic>I enjoy spending time with my children</italic>&#x201D; (rewards), &#x201C;<italic>The major source of stress in my life is my children</italic>&#x201D; (stressors), &#x201C;<italic>I feel overwhelmed by the responsibility of being a parent</italic>&#x201D; (loss of control), and &#x201C;<italic>I am happy in my role as a parent</italic>&#x201D; (satisfaction). Eight items are reverse scored. A total parenting stress score was calculated by adding the subscales (range: 18&#x2013;90) in each sample. Lower scores indicate lower stress levels of stress.

<title>Data Analysis</title>
<p>Statistical analyses were performed using the IBM SPSS 26 (Statistical Package for the Social Sciences). To check for the assumptions of normality, skewness and kurtosis values were calculated for the dimensional variables. None of them presented extreme skewness and kurtosis values falling outside the proposed threshold values of &#x00B1; 2, suggesting a normal distribution for the variables of interest (<xref ref-type="bibr" rid="B21">George and Mallery, 2010</xref>). To compare variables between children receiving SEN support and children not receiving we used Chi-squared tests for categorical variables and independent groups <italic>t</italic>-tests for continuous variables. The effect size of the between-group differences was calculated using Cohen&#x2019;s <italic>d</italic> for continuous variables, and Phi &#x03C6; or Cramer&#x2019;s <italic>V</italic> for categorical or multi-categorical variables, respectively. To compare differences in change in daily habits before and during the lockdown, we used mixed factorial ANOVA with SEN provision (SEN/non-SEN) the between-group factor and time (before/during) the within-group factor. To measure the size of the difference we used the partial eta square. The Bonferroni statistic was used for intergroup and intragroup multiple comparisons. The homogeneity of variance in a few of the daily habit variables was violated because of unequal group sizes. Therefore, we used a more stringent <italic>p</italic>-value level (<italic>p</italic> = 0.01) for these analyses (<xref ref-type="bibr" rid="B68">Tabachnick et al., 2007</xref>).

The variables that significantly differentiated between children with and without SEN support were included in the analysis to control for their effects. In the first regression, sociodemographic variables (<italic>Step</italic> 1) explained a very small proportion of the variance (1.3%) in children&#x2019;s externalizing behavior change score. Higher parenting stress and child mental health difficulties significantly contributed to externalizing behavior change (<italic>Step</italic> 2). The model explained 23.0% of the variance.

<title><italic>Post hoc</italic> Analyses of Suppression Effect</title>
<p>A <italic>net</italic> or <italic>cross-over</italic> suppression refers to cases in which two independent variables and a dependent variable correlate positively with each other, but the inclusion of the two independent variables in the regression equation increases the beta of the most influential variable and changes the beta sign of the weakest variable; that is, a positive zero-correlation becomes a negative beta (<xref ref-type="bibr" rid="B12">Cohen and Cohen, 1975</xref>; <xref ref-type="bibr" rid="B32">MacKinnon et al., 2002</xref>; <xref ref-type="bibr" rid="B55">Paulhus et al., 2004</xref>; <xref ref-type="bibr" rid="B75">Watson et al., 2013</xref>; <xref ref-type="bibr" rid="B61">Salgado et al., 2019</xref>). In the absence of a statistical test to examine suppression effects (<xref ref-type="bibr" rid="B64">Smith et al., 1992</xref>), partial correlation analysis has been suggested to help understand the relationship between the variables involved in a suppression effect (<xref ref-type="bibr" rid="B37">Meehl, 1945</xref>; <xref ref-type="bibr" rid="B73">Velicer, 1978</xref>; <xref ref-type="bibr" rid="B49">Olusegun et al., 2015</xref>). Accordingly, we carried out bivariate, followed by partial correlations, to examine the associations between SEN and externalizing behavior change while controlling for the effect of the variables that significantly predicted externalizing behavior in the final model: child mental health (SDQ), parenting stress (PSS), and co-existence difficulty. The analysis showed that when child mental health was statistically controlled, having SEN was negatively associated with externalizing behavior change (<italic>r</italic> = &#x2013;0.13) (<xref ref-type="table" rid="T5">Table 5</xref>).</p>

<p>Analysis of between-group differences in the mean total internalizing behavior change score showed that according to their caregivers&#x2019; perceptions, the emotional state of children with SEN was not more impacted than the emotional state of children with no SEN. However, an investigation of the distribution of change across internalizing symptoms demonstrated that, despite the lack of difference in total internalizing behavior change score between the groups, the caregivers of children with SEN were more likely to report that their child was more worried and anxious during the lockdown. Analysis of between-group differences in the total externalizing behavior change score showed that the behavior of children with SEN deteriorated significantly more than the behavior of children with no SEN during the lockdown. The caregivers of children with SEN children reported higher levels of anger, frustration, irritability, and behavioral problems. Further analysis showed that the positive association between SEN and negative change in children&#x2019;s externalizing behavior was spurious; once the child&#x2019;s mental health difficulties (SDQ) were held constant, the association became negative. Altogether, our study showed that caregivers with children with SEN were significantly more concerned about the deterioration of their child&#x2019;s behavior compared to those with children with no SEN. While difficulties were found across a range of internalizing and externalizing symptoms, their behavior was more likely to be affected than their emotional state. Our findings agree with the studies that found that children with SEN were more likely to have elevated rates of emotional and behavior difficulties during the lockdown (<xref ref-type="bibr" rid="B46">Nonweiler et al., 2020</xref>; <xref ref-type="bibr" rid="B70">Tso et al., 2020</xref>; <xref ref-type="bibr" rid="B4">Asbury et al., 2021</xref>; <xref ref-type="bibr" rid="B5">Berasategi Sancho et al., 2021</xref>; <xref ref-type="bibr" rid="B13">CO-SPACE, 2021</xref>; <xref ref-type="bibr" rid="B20">Family Fund, 2021</xref>). Because pre-pandemic prevalence of mental health difficulties in England is higher among children with SEN (<xref ref-type="bibr" rid="B35">McGinnity et al., 2005</xref>; <xref ref-type="bibr" rid="B48">Office for National Statistics, 2021</xref>) it is unclear whether the increased behavioral problems of children with SEN in our sample was the result of the lockdown or pre-pandemic poor mental health. However, the <italic>post hoc</italic> analysis showed that the children with SEN who had fewer behavioral difficulties during the lockdown were the ones with stronger mental health. This finding suggests that poor mental health was an important risk factor of poor socioemotional wellbeing in children with SEN during the lockdown. Additionally, it emphasizes the protective role of mental health and wellbeing in children with SEN (<xref ref-type="bibr" rid="B54">Panchal et al., 2021</xref>; <xref ref-type="bibr" rid="B60">Raw et al., 2021</xref>; <xref ref-type="bibr" rid="B74">Waite et al., 2021</xref>) and the need to support the mental health and wellbeing of children and young people with SEN (<xref ref-type="bibr" rid="B63">Skrzypiec et al., 2016</xref>). As well as child mental health, emerging research points out to additional individual factors that may modulate the impact of the COVID-19 lockdown on children&#x2019;s outcomes. For instance, recent research has placed emphasis on the effects of personality traits, coping methods and alexithymia as they were found to have a differential impact on COVID-19 related emotional responses such as anxiety and stress (<xref ref-type="bibr" rid="B52">Osimo et al., 2021</xref>) and emotional eating (<xref ref-type="bibr" rid="B10">Cecchetto et al., 2021</xref>). Additionally, irritability has been suggested to interfere with the emotional state of non-neurotypical children during the lockdown (<xref ref-type="bibr" rid="B71">T&#x00FC;rko&#x011F;lu et al., 2021</xref>; <xref ref-type="bibr" rid="B72">U&#x00E7;ar et al., 2021</xref>). Further research to understand how these individual factors were implicated in the emotional and behavioral wellbeing of children with SEN during the lockdown is warranted.</p>
<p>Another finding was that while, generally, children with SEN were perceived to have worse behavior than children without SEN, the children with SEN but without mental health difficulties behaved better during the lockdown. This finding is compatible with the latest longitudinal findings from the Co-SPACE study which found that particularly younger boys with SEND had less severe hyperactivity and inattention symptoms between June and July 2020 (<xref ref-type="bibr" rid="B60">Raw et al., 2021</xref>). Our finding is also consistent with earlier results from the Co-Space study which revealed reductions in externalizing problems (conduct and hyperactivity/inattention) among children and adolescents with SEND during the early lockdown between March to May 2020 (<xref ref-type="bibr" rid="B74">Waite et al., 2021</xref>) as well as other studies which found that children and young people with SEND reported that their mental health improved during the lockdown (<xref ref-type="bibr" rid="B39">Mind, 2020</xref>; <xref ref-type="bibr" rid="B33">Mansfield et al., 2021</xref>). Hence, it appears that, at least for some children, the lockdown may have eased some challenging areas of life, while children with mental health difficulties were significantly impacted regardless of whether they had SEN. It is important to identify why some children experienced fewer behavior difficulties while not at school; potentially schools cannot meet the needs of all children (<xref ref-type="bibr" rid="B9">Castro-Kemp and Mahmud, 2021</xref>).</p>
<p>The results showed that there was a significant increase in screen time and decrease in sleep time for both groups of children. This finding is in line with other studies of technology use during the pandemic in the general child population across the world (<xref ref-type="bibr" rid="B40">Moore et al., 2020</xref>; <xref ref-type="bibr" rid="B57">Pietrobelli et al., 2020</xref>; <xref ref-type="bibr" rid="B79">Xiang et al., 2020</xref>). While the change in daily screen time increased equally for both groups over a month of lockdown, children with SEN were using screens more often than children with no SEN both before and during the lockdown. The <xref ref-type="bibr" rid="B2">American Academy of Pediatrics Council on Communications and Media (2016)</xref> recommends no more than 2 hours of screen time per day for school-aged children (2016). However, children with SEN including children with anxiety, ASD, learning disabilities, or attention-deficit/hyperactivity disorder tend to use devices as a coping mechanism (<xref ref-type="bibr" rid="B11">Close and Fogler, 2020</xref>). Therefore, determining screen time limits can be especially stressful for families of children with SEN especially during the lockdown. The COVID-19 pandemic has also imposed digital platforms as the only means for people to maintain social and emotional connection (<xref ref-type="bibr" rid="B27">Kanekar and Sharma, 2020</xref>). Research on screen use reflects both positive and negative consequences of screen time on child mental health. Research by the UK <xref ref-type="bibr" rid="B15">Council for Disabled Children (2021)</xref> found that some children with SEN liked not having to go out and interact with others face-to-face. Instead, they learnt how to connect with their friends over online gaming because they found this way of communication easier. Though digital devices kept many of these children socially and emotionally connected, excessive screen time has also negative mental health impacts including attention-deficit symptoms, depression, anxiety, and technology addiction (<xref ref-type="bibr" rid="B3">Amin et al., 2020</xref>; <xref ref-type="bibr" rid="B18">Dienlin and Johannes, 2020</xref>; <xref ref-type="bibr" rid="B30">King et al., 2020</xref>; <xref ref-type="bibr" rid="B31">Lanca and Saw, 2020</xref>; <xref ref-type="bibr" rid="B53">Oswald et al., 2020</xref>; <xref ref-type="bibr" rid="B79">Xiang et al., 2020</xref>; <xref ref-type="bibr" rid="B25">Hudimova, 2021</xref>; <xref ref-type="bibr" rid="B77">Wong et al., 2021</xref>). Because there are mixed consequences of prolonged screen use on children with SEN, further research is necessary to understand how to balance the positive effects of digital social connectedness and negative effects of excessive use in children with SEN.</p>
<p>Families supporting their child&#x2019;s complex and special needs at home had little or no other support (i.e., wider family support, individual educational therapy support, institutional, and mental support) available to them at the time of the lockdown (<xref ref-type="bibr" rid="B67">Su et al., 2021</xref>). Moreover, other lockdown related factors such as lack of coping mechanisms, isolation from social support networks, disruption in routines, challenging family circumstances, and financial hardship might have caused additional difficulties for these families (<xref ref-type="bibr" rid="B38">Merello, 2021</xref>; <xref ref-type="bibr" rid="B67">Su et al., 2021</xref>). In this context, the experience of the confinement and its consequences might have been more challenging for children with SEN and their families. A growing body of research has shown that caregivers with children with SEN/D found caring for their children during the lockdown difficult (<xref ref-type="bibr" rid="B9">Castro-Kemp and Mahmud, 2021</xref>; <xref ref-type="bibr" rid="B26">Kallitsoglou and Topalli, 2021</xref>). As expected, we also found that caregivers with children with SEN reported significantly high rates of family co-existence difficulty. Additionally, they were more likely to report difficulty than caregivers with children without SEN. Notably, however, we found that SEN did not significantly predict co-existence difficulty when child and caregiver characteristics were statistically controlled. Specifically, the findings demonstrated that families with SEN children found the confinement more challenging because of associated family adversity (i.e., poor parental mental health and associated stress around parenting), and the child&#x2019;s poor mental health and not the child&#x2019;s SEN <italic>per se</italic>. Our findings point out to the child&#x2019;s family ecology as a potential explanatory factor of the difficulties that the families with children with SEN experienced during the lockdown. Moreover, they highlight the significance of caregiver and child mental health for a harmonious family life (<xref ref-type="bibr" rid="B59">Prime et al., 2020</xref>).</p>
<p>The findings should be interpreted in relation to the study&#x2019;s methodological limitations. The cross-sectional design did not allow to examine the long-term impact of the lockdown on children&#x2019;s internalizing and externalizing behavior and daily habits. Additionally, changes in children&#x2019;s symptoms were based only on perceived caregiver report. Majority of participants were white female university graduates. Therefore, generalization of the findings should be approached with caution. Furthermore, since we did not have pre-pandemic data, it is difficult to understand if the behavioral symptoms change was due to the lockdown or pre-existing levels of mental health difficulties in children with SEN. Replication studies should include a longitudinal design, multi-informant assessment methods of children&#x2019;s emotional and behavioral difficulties, and examination of passive vs. interactive screen time. These limitations notwithstanding, our findings have implications for supporting families with SEN. Our study showed that poor mental health was an important risk factor of the wellbeing of children with SEN during the pandemic. Mental health lay the foundation from which children and young people can start exploring the learning opportunities available to them (<xref ref-type="bibr" rid="B76">Weisbrot and Ryst, 2020</xref>). Therefore, the aims of education post-pandemic should be re-examined and consider the systematic implementation of school-wide and selective evidence-based intervention programs to support the outcomes of children with SEN. Furthermore, the caregivers with children with SEN who experienced more difficulty with the confinement were those who experienced more adversity such as poor mental health. Consistent with research on family risk and resilience and the benefits of positive parenting for children&#x2019;s emotional and behavioral outcomes before and during the lockdown (<xref ref-type="bibr" rid="B59">Prime et al., 2020</xref>; <xref ref-type="bibr" rid="B60">Raw et al., 2021</xref>), our research calls for more concerted action to support the caregivers of children with SEN.</p>
