Holocaust survivors and their children generally show signs of resilience under normal circumstances but may suffer from increased psychological vulnerability in adverse circumstances (Shmotkin et al., Reference Shmotkin, Shrira, Goldberg and Palgi2011). Thus, Holocaust survivors have displayed greater psychological distress in times of war and when facing illness (Shmotkin et al., Reference Shmotkin, Shrira, Goldberg and Palgi2011). Furthermore, it seems the intergenerational transmission of trauma results, among other things, in hypersensitivity in times of crisis among offspring of Holocaust survivors (OHS).
Many OHS are currently taking care of their aging parents. Shrira et al. (Reference Shrira, Menashe and Bensimon2019) found that OHS whose parents had PTSD reported assisting their parents more with physical and medical care, as well as with instrumental help than offspring whose parents did not undergo the Holocaust. This may suggest that some OHS bear a heavier emotional burden in the context of caring for their parent. Indeed, OHS whose parents had PTSD reported higher levels of filial anxiety (anxiety related to caring for one’s parents) and filial obligation than offspring whose parents did not undergo the Holocaust, wherein the sense of filial obligation mediated the relationship between parental PTSD and offspring filial anxiety (Shrira et al., Reference Shrira, Menashe and Bensimon2019).
The aforementioned study was performed before the outbreak of COVID-19. The COVID-19 pandemic has—among its numerous effects—impacted the emotional state of old people in general and Holocaust survivors in particular. Thus, for instance, Holocaust survivors with PTSD were found to have higher COVID-19 anxiety and increased levels of loneliness during the pandemic (Maytles et al., Reference Maytles, Frenkel-Yosef and Shrira2021).
The pandemic may have increased the caregiver burden experienced by OHS taking care of their parents. For instance, people taking care of their parents (Archer et al., Reference Archer, Reiboldt, Claver and Fay2021) reported an increase in their caregiver burden during the pandemic. Based on previous findings (Shrira et al., Reference Shrira, Menashe and Bensimon2019), caring for Holocaust survivors during the COVID-19 pandemic may prove even more complicated when the survivors have PTSD.
The current study examines caregiver burden among caregivers taking care of their parents during the COVID-19 pandemic. The first hypothesis was that OHS who reported that their care recipients had PTSD would report a heavier caregiver burden compared to OHS who reported that their care recipients did not have PTSD, and relative to comparisons whose care recipients are not Holocaust survivors. The second hypothesis was that relative to the other groups, OHS with parental PTSD would perceive a greater increase in caregiver burden when asked to compare their pre-pandemic burden to current burden.
Method
Participants and procedure
The sample consisted of 109 Israeli Jewish adult caregivers born after 1945, whose parents, all European descent, were born before 1945. Each caregiver had at least one living parent care recipient. The caregivers were divided into three groups: 20 OHS reporting to have at least one care recipient with PTSD, 60 OHS reporting that none of their care recipients suffer from PTSD, and a comparison group of 29 caregivers whose care recipients had not gone through the Holocaust and did not have PTSD (see Table 1 for the three groups’ demographics).
Table 1 Group Differences in the Study Variables
1 When both parents were alive, we computed the average age of both parents. 2A scale assessing help provided to the care recipient with day-to-day tasks (based on Lawton and Brody, Reference Lawton and Brody1969). 3The multidimensional caregiver burden inventory (Novak and Guest, Reference Novak and Guest1989). 4The perceived change in caregiver burden items: these items were worded especially for the current study.
The data were collected from caregivers throughout Israel between November 9, 2020, and February 15, 2021. During this time, COVID-19 morbidity in Israel was at an all-time high. Caregivers were recruited on social media and via organizations supporting Holocaust survivors. Caregivers completed an online questionnaire after consenting to volunteer for a study approved by an ethics committee at Bar-Ilan University.
Measures
Caregivers reported sociodemographic information and were asked which country their care recipients had been born in, had they lived under a Nazi or pro-Nazi regime, and where they had been during the war. Additionally, caregivers completed several questionnaires relating to their care recipients (e.g. the care recipient’s age, the level of support provided by the caregiver, etc.). Caregivers also completed a 6-item scale about helping the care recipient (based on Lawton and Brody, Reference Lawton and Brody1969). Items ranked on a scale of 1 (not helping at all) to 5 (helping all the time). The final score was the ratings’ average (Cronbach’s α = .77).
The multidimensional caregiver burden inventory (Novak and Guest, Reference Novak and Guest1989), which includes 24 items measured the caregiver’s feelings about taking care of their care recipient during the COVID-19 pandemic. Items were rated on a scale of 0 (never) to 4 (almost always). The questionnaire consisted of five subscales, with the final score calculated as the ratings’ average in each subscale: time-dependent burden (α = .86), developmental burden (α = .83), physical burden (α = .72), social burden (α = .74), and emotional burden (α = .78).
Four items measured the perceived change in caregiver burden because of the COVID-19 pandemic. The items were worded especially for the current study and rated on a 5-point scale from −2 (became much worse) to 2 (became much better). These referred to the change in caregiver burden, the quality of the child–parent relationship, the quality of the relationship between the care recipient and her/his friends and family, and the care recipient’s ability to access day-to-day errands.
A SARS-CoV-2 exposure questionnaire (Bergman et al., Reference Bergman, Cohen-Fridel, Shrira, Bodner and Palgi2020), in which caregivers were asked about five events related to SARS-CoV-2 exposure. The score represented the number of exposure events participants had experienced.
A COVID-19 concern questionnaire with 13 items taken from previous studies (Bergman et al., Reference Bergman, Cohen-Fridel, Shrira, Bodner and Palgi2020; Taylor et al., Reference Taylor, Landry, Paluszek, Fergus, McKay and Asmundson2020). The items regarded the caregiver’s worries about the COVID-19 pandemic. The items were rated on a scale of 0 (not worried at all) to 4 (very worried). The final score was the ratings’ average (α = .87).
An ICD-11 PTSD symptom questionnaire (Cloitre et al., Reference Cloitre2018) with six statements measuring posttraumatic stress. The items were rated on a scale of 0 (not at all) to 4 (to a large extent). When filling out the questionnaire, caregivers were asked to report their mother’s (α = .76) and father’s (α = .78) symptoms separately. Offspring reports of parental PTSD symptoms were found to be reliable and correlated with self-reports by parents in previous studies (Yehuda et al., Reference Yehuda2006). Caregivers completed the questionnaire for themselves as well (α = .85). Clinical PTSD levels were determined when at least one symptom in each of the three syndromes (re-experiencing, avoidance, and hyperarousal) were rated as moderately severe or higher.

Data analysis
One-way analyses of variance (ANOVAs), Chi-square tests, and Fisher’s exact tests assessed group differences in background variables. To test the study hypotheses, ANOVAs assessed group differences in caregiver burden subscales and perceived change in caregiver burden. Significant main effects were followed by Bonferroni post hoc tests. Additional analyses of covariance controlled for caregivers’ PTSD symptoms.
Results
There were no significant differences in background variables between the three groups (see Table 1). Similarly, there were no differences between groups in care recipient-related variables (e.g. care recipient’s age, how long the caregiver had been helping the care recipient etc., including the distribution of caregivers whose father, χ 2[2] = 5.15, p = .07, or mother, Fisher’s exact test, p = .93, was alive). A significant difference was found between the groups in the extent of support that caregivers were providing their care recipients (p = .001, η 2 = 0.124). Bonferroni post hoc tests found that OHS with and without parental PTSD reported helping their care recipients more than the comparison group. No differences between the groups were found in SARS-CoV-2 exposure (F[2,108] = 0.10, p = .90) or COVID-19 concern (F[2,108] = 1.52, p = .22).
A significant difference in time-dependent burden was found between the groups (p = .003, η 2 = 0.10). Bonferroni post hoc tests showed that OHS with parental PTSD reported a heavier caregiver burden than the other two groups. There were also significant group differences in developmental (p = .03, η 2 = 0.063), physical (p = .03, η 2 = 0.065), and social burdens (p = .001, η 2 = 0.125). In all these cases, OHS with parental PTSD reported heavier burdens than the comparison group.
There was also a significant difference between the groups in the perceived change in caregiver burden (p = .003, η 2 = 0.105) and in the care recipient’s access to essential services and day-to-day errands (p = .001, η 2 = 0.123). Bonferroni post hoc tests showed that both OHS groups perceived a greater increase in caregiver burden and a greater negative change in care recipient’s access than the comparison group. (Table 1)
Additional analyses controlling for the caregivers’ PTSD symptoms (15.6% of them showed clinical levels) once again showed significant group differences in time-dependent burden (F[2,95] = 5.29, p = .007, η 2 = .10), developmental burden (F[2,94] = 3.69, p = .02, η 2 = .07), social burden (F[2,92] = 9.04, p<.0001, η 2 = .16), the perceived change in caregiver burden during the pandemic (F[2,93] = 4.13, p = .01, η 2 = .08), and changes to care recipient’s accessibility of essential services/day-to-day errands (F[2,93] = 4.28, p = .01, η 2 = .08).
Discussion
This study examined caregiver burden among caregivers taking care of their parents during the COVID-19 pandemic. OHS reported assisting their care recipients more than the comparison group did. This finding may reflect a general pattern found in previous studies, namely, that OHS feel a stronger obligation to help their parent (Shrira et al., Reference Shrira, Menashe and Bensimon2019). It is also possible that this finding reflects the higher support needs of Holocaust survivors who had been traumatized during the war and must now cope with the pandemic. It should be acknowledged that, potentially, Holocaust survivors can display both resilience and vulnerability when faced with the pandemic (e.g. Maytles et al., Reference Maytles, Frenkel-Yosef and Shrira2021).
Our first hypothesis was, for the most part, supported by the finding that OHS with parental PTSD reported the highest caregiver burden in several aspects. The size for the group effects ranged between medium to large. This finding is in line with a previous study done before the pandemic, where OHS whose care recipient parents had PTSD reported higher levels of filial anxiety and obligation than the comparison group (Shrira et al., Reference Shrira, Menashe and Bensimon2019).
Our second hypothesis was that because of the pandemic, OHS with parental PTSD would experience an increase in caregiver burden. In effect, OHS reported an increase in caregiver burden and a greater negative change in the accessibility of day-to-day errands/essential services for their care recipients relative to the comparison group—regardless of whether their care recipients had PTSD. The size for the group effects ranged between medium to large.
The increased caregiver burden during the pandemic is in line with previous studies performed during the pandemic showing an increase in caregiver burden among informal caregivers (Archer et al., Reference Archer, Reiboldt, Claver and Fay2021). A possible explanation for the finding that OHS have experienced a greater increase in caregiver burden than the comparison group has to do with the obligation OHS feel toward their traumatized parents and the survivors’ higher support needs as they face the effects of aging alongside the effects of the Holocaust trauma in a time of pandemic (Maytles et al., Reference Maytles, Frenkel-Yosef and Shrira2021).
The findings of this study should be interpreted in light of its limitations. First, the study used a convenience sampling method. Second, the sample size is relatively small because of the difficulty of finding caregivers whose care recipients have been through the Holocaust and are still alive. The small sample size precluded the use of multivariate models. Third, caregivers did not undergo a clinical interview and were not formally diagnosed with PTSD. Fourth, in this study, caregivers reported their care recipient’s PTSD symptoms. This may have caused a bias—with caregivers either being unaware of their care recipient’s symptoms or reporting symptoms that had manifested in the past but have since subsided. Finally, perceived change in burden required caregivers to recall care demands pre-pandemic, and we cannot be certain whether it reflected objective burden increase.
Further research is needed to study other aspects of caregiver burden carried by OHS. For instance, an additional study could examine caregiver burden in the aftermath of the COVID-19 crisis, when all social distancing measures are lifted. Furthermore, a follow-up study could include additional variables that increase or decrease caregiver burden in this population.
The findings of this study shed light on the way OHS cope with the task of caring for their parents during the COVID-19 pandemic. These findings show that some OHS are at risk of experiencing more distress and may need help and support. Further research is needed to determine whether people taking care of their posttraumatic parents in contexts with additional background trauma also feel a heavier caregiver burden—both in general and specifically during the current pandemic.
