Abstract

Aims

Previous research has shown that people with disabilities are disproportionately vulnerable to symptoms of psychological distress after exposure to armed conflict. Past work has also shown that individuals displaced by conflict are at heightened risk of post-traumatic stress. Using a national online sample of Ukrainians in the early weeks of the 2022 Russian invasion, we aim to examine associations between functional disability and symptoms of post-traumatic stress.

Methods

We examined the association between levels of functional disability in the Ukrainian population and symptoms of post-traumatic stress during the 2022 Russian invasion of Ukraine. We analysed data from a national sample of 2000 participants from across this country, assessing disability using the 12-item World Health Organization Disability Assessment Schedule (WHODAS-12)(six domains of disability) and the International Trauma Questionnaire assessment of post-traumatic stress disorder (PTSD) symptomatology according to the Eleventh Edition of The International Classification of Diseases (ICD-11). Moderated regression examined the impact of displacement status on the disability–post-traumatic stress relationship.

Results

Different domains of disability predicted post-traumatic stress symptoms (PTSSs) to varying extents, with overall disability score significantly associated with PTSSs. This relationship was not moderated by displacement status. Consistent with previous research, females reported higher levels of post-traumatic stress.

Conclusions

In a study of a general population during a time of armed conflict, individuals with more severe disabilities were at greater risk of PTSSs. Psychiatrists and related professionals should consider pre-existing disability as a risk factor for conflict-related post-traumatic stress.

Introduction

Conflict between Russia and Ukraine has been ongoing since 2014, with initial hostilities in Crimea and Donbas followed by a wider Russian invasion in February 2022. As has been seen in other military conflicts, this has had a serious deleterious impact on the mental health of affected populations (Charlson et al., Reference Charlson, van Ommeren, Flaxman, Cornett, Whiteford and Saxena2019; Mesa-Vieira et al., Reference Mesa-Vieira, Haas, Buitrago-Garcia, Roa-Diaz, Minder, Gamba, Salvador, Gomez, Lewis, Gonzalez-Jaramillo, Pahud de Mortanges, Buttia, Muka, Trujillo and Franco2022). Data collected in the early weeks of the 2022 invasion found that 52.7% of respondents reported psychological distress, while 54.1%, 46.8% and 12.1% indicated significant levels of anxiety, depression and insomnia, respectively (Xu et al., Reference Xu, Pavlova, Chen, Petrytsa, Graf-Vlachy and Zhang2023). The ongoing conflict has also led to the substantial displacement of populations within Ukraine, with this population at risk of additional burden on their psychological health. A national survey of Ukrainian internally displaced people (2016) reported a post-traumatic stress disorder (PTSD) prevalence of 32% and 22% for depression and 22% and 17% for anxiety (Roberts et al., Reference Roberts, Makhashvili, Javakhishvili, Karachevskyy, Kharchenko, Shpiker and Richardson2019). A study of elderly individuals conducted in 2016, during a period of active conflict in the aftermath of the annexation of Crimea (Summers et al., Reference Summers, Leidman, Pereira Figueira Periquito and Bilukha2019), found that 34% of respondents living in Ukrainian government–controlled areas and 43% of respondents living in regions not under Ukrainian control showed symptoms of severe psychological distress. These figures should be viewed in the context of extremely high prevalence of mental illness rates in the country before both the current full-scale invasion and the earlier attacks on Crimea and the Donbas. Data collected in 2002 for the Ukraine World Mental Health Survey found lifetime mental illness prevalence of 31.6%, with Ukraine reporting one of the highest suicide rates in Europe (Bromet et al., Reference Bromet, Gluzman, Paniotto, Webb, Tintle, Zakhozha, Havenaar, Gutkovich, Kostyuchenko and Schwartz2005).

People with disabilities can face particularly significant negative mental health consequences after disaster and are at considerable risk following war-related trauma (Stough, Reference Stough, Neria, Galea and Norris2010; Stough and Kelman, Reference Stough, Kelman, Rodriguez, Donner and Trainor2018). Data collected in 2002 from the Afghan population (Cardozo et al., Reference Cardozo, Bilukha, Crawford, Shaikh, Wolfe, Gerber and Anderson2004) found that 72% of respondents with disabilities reported depression, 85% anxiety and 42% PTSD. Those with chronic health conditions and disabilities were at the greatest risk of psychological distress. Consistent with studies elsewhere, which found that women exhibit higher levels of psychopathology during trauma (Brewin et al., Reference Brewin, Andrews and Valentine2000), women reported worse mental health than men. In a subsequent study of Afghan respondents (from 2004 to 2005) (Trani and Bakhshi, Reference Trani and Bakhshi2013), 86% of those with disabilities showed symptoms of potential mental distress using default K6 criteria, with again greater prevalence of distress amongst women.

In the context of the invasion of Ukraine, several researchers have made urgent calls for more data on the impact of the conflict on people with disabilities and for their situations to be given due attention (Patwary et al., Reference Patwary, Polack, Zharkova, Swed and Shoib2022; Ruškus, Reference Ruškus2022). However, despite the evidence of psychological trauma amongst the Ukrainian population and the high risk to mental health of people with disabilities exposed to armed conflict, we know of no previous work that has examined the association between disability severity and post-traumatic stress symptoms (PTSSs) in a general population affected by armed conflict. To this end, we assessed associations between disability and PTSSs in the population employing a web-based sample which aimed to be representative in terms of age and gender, as well as geographical region prior to any displacement. We hypothesise that (a) severity of disability will predict severity of PTSSs and (b) females will experience higher rates of PTSSs (Brewin et al., Reference Brewin, Andrews and Valentine2000). Previous studies indicate that internally displaced people and refugees are systematically more vulnerable to various forms of psychological distress than people who have not been displaced in conflict (Blackmore et al., Reference Blackmore, Boyle, Fazel, Ranasinha, Gray, Fitzgerald, Misso and Gibson-Helm2020), and we expect to replicate this trend. We also explore the extent to which this displacement will moderate any association between disability and post-traumatic stress.

Methods

Recruitment and sample

We collected data in the first weeks after the invasion, during which attacks from Russia occurred across the whole country. We report analysis of secondary data from an online sample of 2000 people aged 18–55 surveyed in Ukraine between 7 and 15 April 2022 (M age 37.18 years, SD = 9.3), 1026 (51.3%) female (see also Ben-Ezra et al., Reference Ben-Ezra, Goodwin, Leshem and Hamama-Raz2023). We used an existing panel maintained by the Ukrainian branch of the survey company Kantar, aiming at obtaining representation of age, sex and region (before displacement). Data were collected in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines for observational studies (von Elm et al., Reference von Elm, Altman, Egger, Pocock, Gotzsche, Vandenbroucke and Initiative2008).

Each participant received a digital invitation and provided electronic informed consent. Inclusion criteria were age (18–55) and fluency in Ukrainian. Using G*Power (v. 3.1.9.4) (Faul et al., Reference Faul, Erdfelder, Lang and Buchner2007, Reference Faul, Erdfelder, Buchner and Lang2009), we estimated a sample of 1975 participants to be required to detect low-medium effect sizes of 0.20, with 99% power and a 1% significance level. Of 2765 who clicked through to the survey, 176 (6.4%) were omitted for failing to meet inclusion criteria, a further 326 (11.8%) dropped out and 263 (9.5%) were removed to meet quotas for representative sampling. Of our 2000 respondents, 1455 individuals (72.8%) were not displaced, 389 (19.4%) displaced inside of Ukraine and 156 (6.6%) displaced outside of Ukraine. In terms of the major Ukrainian regions of origin, 569 individuals (28.5%) were from the East, 358 (17.9%) from the West, 483 (24.2%) from Kyiv, 160 (8%) from the North, 217 (10.8%) from the Centre and 213 (10.6%) from the South. Further sample descriptives are presented in Table 1. The dataset is available on the Open Science Framework (https://osf.io/z5adg/).

Research ethics approval statement

All participants provided informed consent. Ethical approval for original data collection was provided by the University Ethics Committee of the final author (AU-SOC-YHR-20220311). Approval for this re-analysis was provided by the Ethics Committee of the first author (University of Warwick, Psychology: PGR_21-22/35). All aspects of this research were performed in accordance with the principles of the Declaration of Helsinki (World Medical Association, 2013).

Measures

PTSSs were assessed using six items from the International Trauma Questionnaire (ITQ) (Cloitre et al., Reference Cloitre, Shevlin, Brewin, Bisson, Roberts, Maercker, Karatzias and Hyland2018) previously validated for use with the Ukrainian population (Shevlin et al., Reference Shevlin, Hyland, Vallieres, Bisson, Makhashvili, Javakhishvili, Shpiker and Roberts2018). Participants were asked how much they were bothered by each of six symptoms (e.g. ‘feeling jumpy or easily startled’) in the previous month and responded on a five-point Likert scale ranging from not at all (0) to extremely (4) (α = 0.86). Possible scores ranged between 0 and 24.

Disability status was measured using the 12-item World Health Organization Disability Assessment Schedule (WHODAS) 2.0 (Üstün et al., Reference Üstün, Kostanjesek, Chatterji and Rehm2010). The WHODAS 2.0 conceptualizes disability in accordance with the International Classification of Functioning (ICF) (World Health Organization, 2001) and encourages a holistic view of individual functioning across different domains. In line with current sociological thinking in disability studies (Shakespeare, Reference Shakespeare2017), we chose to focus on individual functioning, regardless of diagnostic labels. This tool has previously demonstrated reliability and validity in international use (Federici et al., Reference Federici, Bracalenti, Meloni and Luciano2017), although only the full 36-item version has been previously used in the Ukrainian context. The 12 items measure difficulties in six different domains of functioning, with two items per domain: (1) Cognition; (2) Mobility; (3) Self-care; (4) Getting along with others; (5) Life activities and (6) Participation (overall α = 0.91). Respondents indicated the level of difficulty they had with each item using a five-point Likert scale, from none (1) to extreme or cannot do (5). We used the simple scoring method (Üstün et al., Reference Üstün, Kostanjesek, Chatterji and Rehm2010) adding together scores to create a single overall score (from 12 [no disability] to 60 [complete disability]).

To assess displacement, respondents were coded as Displaced if they either had been forced to move within Ukraine as result of the conflict or had to leave the country because of the war.

Analyses

To assess associations between disability and PTSS, we initially ran Pearson correlations between each subscale of the WHODAS-12 and the total post-traumatic stress score from the ITQ. We then ran a moderated regression with WHODAS-12 total score as the focal predictor and post-traumatic stress score as the outcome. Displacement status was used as the moderator, with sex as a covariate. All analyses were conducted using SPSS version 27. Moderated regression was conducted using the process macro (Hayes, Reference Hayes2022) with a heteroscedasticity-consistent standard error estimator (Hayes and Cai, Reference Hayes and Cai2007).

Results

Mean PTSS score was 11.64 (range 0–24, SD = 4.91) and PTSD prevalence was 30.8%. Mean disability (WHODAS-12) score was 10.51 (possible range = 12–60, SD = 8.65). Average WHODAS-12 (disability) subscale scores ranged from 1.07 (SD = 1.67) for self-care to 2.17 (SD = 1.87) for participation in society. There were moderate positive zero-order correlations between each of the disability measures and PTSSs. All six of the disability sub-scales were significantly associated with PTSD symptoms as demonstrated by the Spearman correlation coefficients of 0.30 (self-care)–0.45 (participation in society), all P < 0.001) (Table 2).

** P < 0.01 level (two-tailed).

In line with our first hypothesis, a moderated regression model (Table 3) indicated that increasing levels of functional disability in the Ukrainian population predicted greater endorsement of PTSSs (β = 0.27, t = 21.67, P = < 0.001). Also, as anticipated, displacement was significantly associated with PTSSs, although the disability–PTSSs relationship was not moderated by displacement (β = −0.01, t = −0.43, P = 0.67). Women exhibited more PTSSs (β = 1.71, t = 8.88, P = < 0.001).

Discussion

In this paper, we present one of the first analyses to examine associations between disability severity and PTSSs during a period of war. We find that women and people with more severe disabilities endorsed greater PTSSs, as do those who are displaced, but there was no moderation of the disability–post-traumatic stress relationship by displacement.

A variety of disabilities including vision impairment (Bonsaksen et al., Reference Bonsaksen, Brunes and Heir2022), physical disability (Turner et al., Reference Turner, Lloyd and Taylor2006) and autism spectrum disorders (Lai et al., Reference Lai, Kassee, Besney, Bonato, Hull, Mandy, Szatmari and Ameis2019) have each been previously associated with increased vulnerability to PTSD. The associations between PTSSs and all six dimensions of the WHODAS-12 suggest that increasing disability severity may make individuals more vulnerable to post-traumatic stress during a period of conflict. At the same time, there were differences in associations between disability and PTSSs by disability domain. Self-care was the dimension most weakly associated with post-traumatic stress, while impairments related to social functioning had the strongest association. This may be because respondents with those impairments which make self-care more difficult may not be available when sampling a general population, given that the Ukrainian health and social care system is most likely to place these people in an institutional setting.

Previous research (Blackmore et al., Reference Blackmore, Boyle, Fazel, Ranasinha, Gray, Fitzgerald, Misso and Gibson-Helm2020; Johnson et al., Reference Johnson, Antonaccio, Botchkovar and Hobfoll2021) has suggested that refugees and internally displaced people are at heightened risk for a variety of mental health problems when compared to individuals who have not been displaced. While we did find that displacement status was associated with PTSSs, this did not have a moderating role in the disability–post-traumatic stress relationship. This may be because of a lack of possibility for movement amongst refugees with disability. While housing, employment and access to health and support services were already problematic for Ukrainians with disabilities living in the Donetsk and Luhansk Oblasts in the east of the country (Gazizullin and Solodova, Reference Gazizullin and Solodova2019), it may have been particularly difficult for people with disabilities in these populations to move. Indeed, previous research on predictors of mobility among Ukrainians after the annexation of Crimea in 2014 (Mykhnenko et al., Reference Mykhnenko, Delahaye and Mehdi2022) finds that people with disabilities were less likely to leave their homes than their nondisabled counterparts. Mobility may also be challenging for those suffering with cognitive challenges (e.g., inability to concentrate) or high levels of social anxiety who may feel less able and confident to leave familiar surroundings in favour of an unknown, albeit potentially safer, destination. Our finding that female gender is associated with greater endorsement of PTSSs is consistent with previous studies of populations exposed to war-related trauma (Charlson et al., Reference Charlson, Flaxman, Ferrari, Vos, Steel and Whiteford2016).

Our study has several strengths. We present a novel examination of disability and PTSD symptoms during conflict employing the widely used WHODAS 2.0 12-item measure of disability. We note that our disability scores measured using WHODAS 2.0 in the Ukrainian population five weeks after the Russian invasion were only slightly higher than previously established norms for the Polish population using the same scoring method, during peacetime (Cwirlej-Sozanska et al., Reference Cwirlej-Sozanska, Sozanski, Kotarski, Wilmowska-Pietruszynska and Wisniowska-Szurlej2020). This suggests that our measure accurately depicts the prevalence of pre-existing functional impairment in the Ukrainian population and is not overly biased by the presence of newly acquired disabilities caused by the conflict.

At the same time, we recognize several limitations. First, this study was of the Ukrainian general population. There are substantial differences in the treatment of people with and without disabilities in Ukraine. As a result of the Soviet past – and continued influence of Soviet and Russian traditions even following the independence of Ukraine – people with disabilities do not have equal rights (Phillips, Reference Phillips2009) with many placed in long-term institutional care (Shaw, Reference Shaw2022). This means that people with especially severe disabilities who we might infer would be at the highest levels of risk from PTSD after being exposed to the war were largely inaccessible for the study. Second, because we assessed PTSD symptoms in the early weeks of the Russian invasion, we focused on PTSSs using the International Trauma Questionnaire but did not assess PTSD symptoms prior to the invasion. Third, because we take the approach that diagnostic labels are less important than levels of functioning across the different domains under consideration, we did not explicitly ask about types of disabilities. This meant we were unable to identify any specific disabilities associated with PTSD symptomology. We recognize that future work might also fruitfully complement our current approach with more detail about specific disabilities. Finally, we excluded participants over the age of 55 due to their more limited use of the internet in Ukraine. This nevertheless restricted our analyses of age effects on PTSD symptoms.

Our study has several implications for practitioners. First, we add to the existing literature on war trauma and disability by showing that a range of disability/functional impairments may place patients at risk of post-traumatic stress. Given this range of risk factors, health professionals should take account of the broader infrastructure and environmental damage caused by conflict and its implications for social functioning as well as daily care for many people with disabilities (Racioppi et al., Reference Racioppi, Rutter, Nitzan, Borojevic, Carr, Grygaski, Jarosinska, Netanyahu, Schmoll, Stuetzle, Van Den Akker and Kluge2022). Practitioners need to make use of evidence-based strategies for improving psychosocial health in emergencies (Weissbecker et al., Reference Weissbecker, Bhaird, Alves, Ventevogel, Willhoite, Hijazi, Hanna, Atukunda Friberg, Dakkak and van Ommeren2023) with particular reference to the unique needs of people with different disabilities. In this case, medical personnel may also wish to direct people with disabilities to services and support groups that not only assist in meeting their basic needs but provide opportunities for building or augmenting a social support network. This support is likely to be important for people with disabilities in general (Honey et al., Reference Honey, Emerson and Llewellyn2011) and those relocated as a result of conflict.
