Parents Are Stressed! Patterns of Parent Stress Across COVID-19

Background: The Coronavirus Disease 2019 (COVID-19) pandemic has caused numerous unexpected challenges for many families, and these long-lasting demands likely contribute to higher stress for parents. The aim of this study was to describe changes in parent stress longitudinally from before (retrospective) to two timepoints during COVID-19. Stressors that influenced parenting and strategies to manage parenting difficulties at each timepoint during COVID-19 are also described. Methods: Parents (N = 433; 95% female) in the US with >1 child aged 5–18 years completed an online survey in May 2020 (T1; at the peak of stay-at-home mandates) and in September 2020 (T2; children's return to school). Surveys included the 10-item Perceived Stress Scale (PSS) and questions on parenting-specific stress, stressors that influenced parenting, and strategies to manage parenting difficulties during COVID-19. Retrospective report of pre-COVID-19 stress was assessed at T1; current stress was assessed at T1 and T2. Repeated measures analysis of variance examined changes in stress over time. Results: Parent's stress increased from before COVID-19 to T1 (PSS score: 16.3 ± 5.7 to 22.0 ± 6.4, respectively; p < 0.01), and decreased by T2 (19.2 ± 6.0), but remained elevated above pre-COVID-19 values (p < 0.01). Most parents (71.1%) reported an increase parenting-specific stress from before COVID-19 to T1, which continued to increase for 55% of parents at T2. Common stressors that impacted parenting during COVID-19 were changes in children's routines, worry about COVID-19, and online schooling demands. Common strategies parents used to manage parenting difficulties included doing family activities together, keeping in touch with family/friends virtually, and keeping children on daily routines. Conclusions: Parent stress increased substantially during COVID-19 and has not returned to pre-COVID-19 levels, suggesting the need for enhanced mental health resources and supports. Public health interventions should address parenting-specific stressors and effective strategies for managing parenting difficulties to mitigate their deleterious impact.


INTRODUCTION
The Coronavirus Disease 2019  has swept the globe causing new and unexpected challenges, including severe financial losses, concerns around contracting COVID-19, and mandatory stay-at-home orders disrupting families' daily routines. These challenges have contributed to a heightened awareness among clinicians (1), researchers (2,3) and public health organizations (4,5) of the potential for substantial increased family stress. Furthermore, given the persistent and repeated demands of this pandemic, many families are likely experiencing chronic stress, which is concerning given the physiological and emotional consequences of chronically elevated stress (6), such as increased risk for cardiovascular disease (7), obesity (8), altered respiratory patterns (9), and depression (10).
Previous infection outbreaks have resulted in profound psychosocial consequences (11,12), and emerging evidence during COVID-19 has shown similar patterns (13,14), particularly for parents (15,16). A recent nationwide poll found that US parents are experiencing higher levels of stress during COVID-19, compared to adults without children, given the added challenges of managing children's at-home schooling, halts to extracurricular activities, and navigating children's emotions around uncertainty and change (17). To further this evidence, research is needed to examine how parent stress has changed over the course of this pandemic, and the specific stressors causing parenting difficulties. This is especially important to examine at key timepoints during COVID-19 where parents stress is likely high, including the peak of government closures and stay-athome orders (approximately May 2020) and upon children's return to school in Fall (approximately September 2020). These data can be used to better understand the psychological impact of COVID-19 on parents' mental health and how this pandemic is affecting families over time.
Effective stress management is essential to mitigate the deleterious impact of COVID-19. To manage pandemic-related stress, professional organizations such as the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) recommend strategies such as setting a routine, taking time to unwind, connecting with others, and staying informed while limiting the amount of news that causes distress (4,5). However, it is unknown which specific strategies parents are using to effectively manage their stress and parenting difficulties, and the extent to which certain strategies change throughout the course of COVID-19. Data on parents' use and effectiveness of stress management techniques would be useful to understanding how parents cope over time and to inform initiatives that help improve families' health and well-being. Targeted public health efforts can then be developed and implemented for prevention and stress management to address parents' emotional well-being and provide support.
The aim of this paper is to examine changes in parents' perceived stress, from before to throughout COVID-19. Data were collected at two key timepoints during COVID-19 (May and September 2020). Additionally, at each timepoint, pandemicrelated stressors that parents report as having impacted their parenting during COVID-19, and strategies they found effective at managing stress and parenting difficulties are described.

Study Design and Participant Sample
A longitudinal, observational study utilizing an online survey was conducted at two separate timepoints in May (T1) and September 2020 (T2). At T1, parents were asked about their general and parenting-specific stress before COVID-19 (retrospective report), as well as currently during COVID-19. Parents were also asked about stressors that currently influenced their parenting and strategies they found effective at managing parenting difficulties during COVID-19. The same survey was administered at T2 where parents only reported on their current perceptions of these constructs.

Procedures
The first online survey administered at T1 occurred during the peak of government-mandated stay-at-home orders between April 30, 2020 and May 23, 2020, approximately 4 months after the start of the COVID-19 in the US (18) and a few weeks after most states had closed schools (19). Participants were recruited nationwide through: (1) Facebook advertisements targeting parents with lower educational attainment and living in lower-income ZIP codes; and (2) a snowballing technique using emails sent to colleagues across different sectors (e.g., academic, community partners, schools, non-profit organizations) and postings on social media platforms (e.g., Twitter, parenting forums, and university pages on Facebook). Interested participants were directed to the survey site using Qualtrics, where an informational letter provided details of the study. Passive permission was used to obtain informed consent. Screening questions assessed eligibility, including if participants lived in the US, were >18 years of age, and had >1 child that was 5-18 years of age. The eligibility criteria for child age was chosen in order to recruit parents of school-aged children affected by school closures. Parents who responded affirmatively to these questions were eligible and prompted to complete the full survey (n = 58 parents were not eligible). To ensure that all completed responses were valid (e.g., not bots), the study used Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) features and the research staff continuously monitored all survey responses. Upon survey completion, each respondent was contacted to provide compensation and ensure the responses were from humans. A total of n = 603 parents completed the first survey, and n = 19 were excluded due to invalid survey responses from bots (resulting in n = 584). Of these, n = 433 also completed the second survey at T2 (74% retention). These analyses include the N = 433 who completed both surveys. Parents who did not complete the second survey were more likely to be Hispanic/Latino (p < 0.01) and non-White (p = 0.03). There were no other differences for demographic or perceived general stress scores between parents who did vs. did not complete the second survey. The study procedures and passive consent process were approved by the Institutional Review Board at [redacted] University.

Parenting Difficulty
Parenting difficulty was assessed at each timepoint using a singleitem question asking, "How difficult have the past few weeks been for you to continue parenting in the same as you did prior to COVID-19?" Response options included not difficult at all, somewhat difficult, very difficult, or extremely difficult.

Factors Influencing Parenting
At each timepoint, parents were provided with a list of nine possible stressors and asked to select which impacted their parenting during COVID-19. Stressors included a lack of money, lack of food, lack of time due to increased work tasks, lack of time due to increased household tasks, change in daily routines and structure, parents' worry/anxiety around COVID-19, child's worry/anxiety around COVID-19, child's online schooling at home demands, and child's desire to be with friends. Parents selected all that applied. There was a response option for "other, " where parents were prompted to provide a short answer response. This list of stressors was developed by experts on the research team, given the lack of existing measures assessing COVID-19specific stressors for parents at the time this study was conducted.

Strategies to Manage Parenting Difficulties
At each timepoint, parents were provided with a list of nine possible strategies and asked to select which of these they found effective at managing parenting difficulties during COVID-19. Strategies included using extended family for resources, using community resources, keeping in touch with family/friends virtually, keeping their child on a daily routine, doing family activities together, finding ways to effectively manage anxiety, controlling the information they seek on COVID-19, focusing on the big priorities and letting the small tasks go, and taking time for myself. Parents selected all that applied and could also choose "other" to provide an alternative short answer response. This list of strategies was developed by experts on the research team, given the purpose of examining COVID-19-specific strategies, and the lack of COVID-19-specific measures at study onset.

Demographics and COVID-19-Specific Questions
At T1 only, parents answered demographic questions including parent age, sex, race, ethnicity, education, marital status, family income, insurance status, and the total number of children and adults in the home. Additional COVID-19-related questions were asked at both timepoints, including family diagnoses, working from home, job layoffs/furloughs, income changes, and unemployment benefits.

Statistical Analysis
Means, standard deviations, and percentages were calculated for demographic and COVID-19-related variables as appropriate. A repeated measures analysis of variance model examined patterns of parents' perceived stress over time, from before to across COVID-19. Pairwise comparisons examined differences during COVID-19 at T1 and T2, relative to before COVID-19 (reference timepoint). Values are presented as mean [95% confidence interval (CI)]. A chi square test of independence was used to examine if the distribution of parents with high, moderate, or low stress differed at each timepoint. Furthermore, percentages were calculated for response options pertaining to factors causing parenting difficulties and strategies to manage parenting difficulties at T1 and T2. Thematic analyses were applied to the "other" responses provided, and categories were created. Two researchers (ELA and DS) created categories and independently rated each parent response into one or more categories. Ratings were compared between researchers, and discrepancies were discussed and resolved using a third person (MKB) when needed. Data were analyzed using SAS statistical software, version 9.4 (SAS Institute Inc., Cary, NC, USA), and significance was set at p < 0.05.

Demographics and COVID-19 Related Factors
Parents were mostly female, White, and married or living with a domestic partner; almost half earned a family income of <$50,000/year ( Table 1). COVID-19 related factors, including family diagnoses, work, and income-related changes, are listed in Table 1. Most (∼60%) families experienced a decrease in income from before COVID-19 to T1, while 40% of families experienced a continual decrease through T2. At T2, ∼40% of families reported having a family job loss / furlough since the start of COVID-19, and most children (63.1%) were attending virtual school (19.4% in-person; 17.6% hybrid).

Perceived General Stress and Parenting-Specific Stress
Average scores on the PSS changed over time (p < 0.01). Specifically, scores increased from before COVID-19 (  Decreased family income in September 2020 was relative to May 2020. at T1 and 12.2% at T2 (Figure 1). Almost three-fourths of parents (71.1%) reported an increase in parenting-specific stress from before COVID-19 to T1, which continued to increase for 55% of parents from T1 to T2. At T1, 85% of parents reported it was at least somewhat difficult to continue parenting in the same way as they did prior to COVID-19, while 45% reported that parenting had become harder at T2, compared to at T1.

Pandemic-Related Factors Impacting Parenting During COVID-19
Specific factors that parents felt impacted their parenting during COVID-19 are illustrated in Figure 2, according to parents' perceived stress category from the PSS at each timepoint. The most common stressor was a change in children's daily structure and routines (reported by 86% of parents at T1; 69% at T2). A high percentage of parents also reported that their worry and anxiety around COVID-19 (67% at T1; 49% at T2) and demands related to children's online schooling at home (67% at T1; 60% at T2) impacted their parenting during the pandemic. The overall percentage of parents who reported that a given stressor impacted their parenting tended to decrease from T1 to T2. The greatest decreases in prevalence from T1 to T2 was regarding changes to children's daily structure and routines (17.6% fewer parents) and parents' and children's worry and anxiety around COVID-19 (18.3 and 11.3% fewer parents, respectively). From T1 to T2, an additional 7.2% of parents reported that a lack of time due to increased work tasks and 1.9% reported that a lack of time due to increased household tasks impacted their parenting. There were 103 total unique "other" answers provided (n = 60 at T1; n = 43 at T2). These responses were categorized ( Table 2) with example quotes for each category to provide representation of these answers. Figure 3 illustrates strategies that parents found effective at managing parenting difficulties during COVID-19, according to perceived stress category at each timepoint. The most common strategies included doing family activities together (reported by 72% of parents at T1; 66% at T2), keeping in touch with family/friends virtually (68% at T1; 56% at T2), and keeping children on a daily routine (53% at T1; 59% at T2). The overall percentage of parents who reported a given strategy was effective at managing their parenting difficulties increased for some strategies and decreased for other strategies over time.

Strategies to Manage Parenting Difficulties
Using extended family for resources and keeping their child on a daily routine increased the most (by ∼7-8% of parents) from T1 to T2, while using community resources, keeping in touch with family and friends virtually, and controlling the information they seek on COVID-19 decreased the most (by ∼8-13% of parents) from T1 to T2. There were N = 23 total "other" strategies reported (n = 17 at T1; n = 6 at T2). Of these, the most common was engaging in hobbies/exercise (n = 8; e.g., "We have started taking daily walks outside"; "Escape to Netflix, Hulu"). Other responses included making family changes (n = 3; e.g., "Family meals are more often and when we come together after work and school"), adapting their mental and spiritual outlook (n = 4; e.g., "accepting the need to be flexible"; "prayer and virtual church"), and cutting back (n = 3; e.g., "doing less for my job;" "not listening to the news").

DISCUSSION
This study showed an increase in general stress from before COVID-19 (retrospective report) to May 2020; although stress decreased by September 2020, it remained relatively greater than retrospectively reported pre-COVID-19 values. Moreover, parenting-specific stress also increased from before COVID-19 to May 2020 and continued to increase for just over half of all parents by September 2020. The majority of parents reported that it was difficult to continue parenting in the same way as they did prior to COVID-19, while almost half reported that parenting had become harder over the course of the pandemic. The most common factors that influenced parenting were changes in children's daily structure and routines, worry and anxiety around COVID-19, and demands related to children's online schooling at home. To manage these difficulties, most parents found that doing family activities together, keeping in touch with family/friends virtually, and keeping children on a daily routine were effective. These findings highlight the need to address the stress that families are experiencing and provide adequate resources to manage this stress during COVID-19. Around the height of government closures and stay-athome orders (May 2020), one-in-five parents reported high stress, while three-in-four parents reported increased parentingspecific stress. Multiple other studies have found that high stress was a common initial reaction to this pandemic (26)(27)(28)(29)(30) and that parents are experiencing more stress than non-parents (17). These previous data were mostly collected in April/May 2020; therefore, the unique aspect of this study includes the longitudinal data across two timepoints during COVID-19 (May and September 2020), as the pandemic progressed. Our findings demonstrated that while general stress is decreased over the course of COVID-19, parenting-specific stress is increased for many families. Disseminating these findings provides scientific evidence to validate parents' experiences during this time and highlights the critical need to reduce this burden. To support parents during these unprecedented times, public health messaging should continue to promote healthy ways for coping and provide information on managing stress for parenting-specific challenges. For example, organizations like the CDC, WHO, UNICEF, and others have collaborated to provide open access, online resources for evidence-based strategies in managing parenting stress during COVID-19 (31). Future research is needed to examine if families are using resources such as these, and if they help to mitigate stress. Furthermore, policymakers at multiple levels (e.g., local, state, schools, employers) should consider the potential impact of COVID-19 policy changes on parents' stress and include thoughtful resources to help mitigate this impact (e.g., providing coordinated strategies for parents to help mitigate the impact of school and childcare closures). There is a dire need for coordinated efforts among policymakers to prioritize these systemic changes to reduce the impact of COVID-19 on parents and families.
The most commonly reported factor that influenced parenting during COVID-19 was a change in children's daily structure and routines. Most children thrive under predictable routines, which makes them feel safe and secure, contribute to healthy habits, and lead to less problematic behaviors (28). Structure and routines also benefit parents by helping them feel organized and in control, which increases parenting competence and reduces daily stress (32). In May 2020, about half of families reported that keeping children on a daily routine was effective in managing parenting difficulties, and over time, this percentage increased, suggesting this strategy was working for more families. A previous study also found that maintaining family FIGURE 2 | Pandemic-related factors that parents reported as having impacted their parenting during COVID-19 in May and September 2020, illustrated by parent-reported stress levels (low, moderate, or high) at that corresponding timepoint. Data collected in a nationwide sample of US parents with a child 5-18 years of age (N = 433). Parents could have selected more than one factor. routines helped children to cope with COVID-19-related stress (27). During this time of unpredictability in a rapidly changing environment, it can be difficult for families to keep a consistent daily routine. Parents who are experiencing high stress and have not yet created a daily routine at home may benefit from creating a schedule together with their children, and parents who have established a daily routine need flexibility to adapt to the ever-changing circumstances. It is important for parents to receive guidance from health care professionals on the importance of creating daily structure and routines, as well as education and support from mental health providers on how to best create adaptable routines with their child.
Routines may include designated time for children's online schooling, which was another common factor that parents felt greatly impacted their parenting. During COVID-19, many parents have had to take on the additional role of teaching their children from home, amongst other work and household tasks. At a time when almost all schools were closed, twothirds of parents report that children's online schooling impacted their parenting, which decreased slightly 4 months later, when some schools resumed in-person or hybrid instruction. Many parents expressed that limited time due to work and household demands were common stressors, which increased in prevalence over time. Parents are understandably overwhelmed by the many responsibilities and roles they have had to take on; for example, one parent mentioned that, "juggling all responsibilities at the same time instead of getting dedicated time for different responsibilities, " impacted her parenting. In addition to parents having to cope with these changes, children are also coping with the lack of sociability from friends and structure that school and extracurricular activities provide. In fact, just over half of parents at both timepoints reported that children's desire to be with friends have impacted their parenting. Doing family activities together at home and connecting with family and friends virtually are ways to help with coping, bonding, and providing sociability in an environment that limits social interactions (4,5,31).
In May 2020, another common stressor was managing parents' worry and anxiety around COVID-19. These findings are similar to another study that found reading/hearing about the severity and contagiousness of COVID-19 was the most commonly experienced stressor among a sample of US adults (33). With an abundance of information available, it is important for families to stay informed, yet to also limit the amount and source of information that may be causing anxiety. Organizations such as the CDC and WHO recommend taking breaks from listening to the news and reading about COVID-19, including posts on social media (4,5). Just under half of parents in this study reported that controlling the information they seek 2 | Parent "other" responses to factors influencing parenting difficulties during the COVID-19 pandemic, categorized by topic.

on COVID-19 and finding ways to effectively manage their anxiety were effective in reducing parenting difficulties. Other ways in which parents effectively managed their anxiety and stress included engaging in hobbies and exercise, such as going on family walks, taking time for themselves, and adapting their mental outlook. By September 2020, there was a decrease in the percentage of parents who reporting their worry and anxiety around COVID-19 was impacting their parenting, thus suggesting that perhaps parents are finding ways to effectively manage this anxiety, or that their anxiety has naturally lessened over time.
For some parents, prolonged periods of high stress may result in substantial mental health impacts including greater depression, anxiety, and reduced quality of life (34). These mental health impacts could be temporary during COVID-19; however, high amounts of stress have been associated with maladaptive behavior changes, including substance abuse, eating behavior changes, and excessive alcohol consumption (30), that could persist even after stress dissipates. Given potential for a looming mental health crisis, adequate access to quality mental and behavioral health care is of paramount importance (35). Yet, prior to COVID-19, access to mental health resources did not meet the needs (neither the quality nor quantity) for millions of Americans (36), with particular concern about inadequate access for families with Medicaid. Furthermore, healthcare costs have long been a significant barrier to providing mental health resources for those who are uninsured (37). During COVID-19, millions of Americans have become unemployed and lost employer-provided insurance, further reducing access to mental health resources; thus, families who are more likely to need these mental health resources may not be able to access them. In response to this, the Society of Behavioral Medicine has issued a policy brief outlining recommendations for increasing access to mental health services to manage parent and family stress (31), the Centers for Medicare & Medicaid Services has expanded access to telehealth services, including the provision of mental health, during COVID-19 (38), and The National Alliance on Mental Illness has provided a COVID-19 resource and information guide for finding free in-person and online mental health support (39). While these initiatives represent initial strategies to address the increased mental health concerns, additional public health and policy responses are urgent to prevent an impending mental health crisis (40). Moreover, some insurers have already modified their policies that previously increased telehealth coverage and access due to COVID-19; yet these changes are being made where there is no corresponding reduction in need and the impacts of COVID-19 persist (41,42).
Study limitations include use of a self-reported questionnaire with retrospective parent reported regarding before-COVID-19. Obtaining baseline measures of parents' perceived stress was not feasible given the sudden onset of this pandemic. To minimize recall bias, the first survey was administered only a few months after the start of COVID-19, yet responses for pre-COVID-19 values were likely influenced by parents' current stress, the media, and other unmeasured biases. This study also used items developed by the research team to assess factors that influenced parenting and effective strategies to manage parenting difficulties. At the time of study onset, measures on COVID-19 specific stressors and parenting strategies did not exist, yet many are now available for future research (43). Response options for these questions may not have encompassed all possible stressors and coping strategies, so to overcome this limitation to some extent, an option of "other" was included where parents could provide an alternative response. These "other" responses represent a small percentage of respondents yet provide rich data and a unique perspective on some of the stressors and coping strategies that parents were using. Other limitations include a sample of mostly mothers with limited racial/ethnic diversity (i.e., mostly White) that is not a nationally representative of all US parents, thus limiting generalizability of these findings; however, this sample did provide a diversity across family income and parent education. Parents who did not complete the second survey tended to be from racial/ethnic minority backgrounds and given these populations often experience greater stress (44), these results could underestimate the stress experienced in more vulnerable, minority populations. Lastly, parental stress could have varied across geographical locations where different policies were enforced at the time of survey completion. Larger, more nationally representative data sets, such as the Stress in America Poll (17), should be referenced for changes in stress across a broader US population and by location.

CONCLUSION
This study provides timely data regarding the significant increase in parents' stress over the initial course of COVID-19, as stayat-home orders were eased, and some children returned to school. Information from this study can be used to advocate for policies that support parents and families, including access to appropriate mental health resources to mitigate the negative impacts for those in need. Given the potential for an impending mental health crisis, adequate access to quality behavioral health services, including remote telehealth options, and workplace policies to accommodate families during this time are necessary for managing the chronic stress experienced by many parents. Specific parenting stressors and strategies parents found effective at managing parenting difficulties can be used to inform stress management initiatives and targeted prevention messaging specific to parenting challenges during the COVID-19 pandemic.
