Abstract
BACKGROUND:
Mental distress is often endured by injured workers participating in the rehabilitation or return to work process following a physical injury. Delays in detecting the onset and treating mental distress can lead to a diverse range of cognitive and behavioural changes that may precipitate psychological distress such as anxiety, depression, and posttraumatic stress.
OBJECTIVE:
The objective of this scoping review was to provide an overview of existing health questionnaires utilised by health care providers and affiliated researchers. It reviewed their effectiveness and suitability to detect mental distress endured by injured workers engaged in the return to work process.
METHODS:
A scoping review methodology was conducted using the Arksey and O’Malley framework which examined peer-reviewed articles published between 2000 and March 2020 comprising health questionnaires. Database searches included Medline, CINAHL, EMBASE and PsycINFO combining specific MeSH terms and key words.
RESULTS:
The full search identified 3168 articles. Following full screening a total of 164 articles reviewed the use of health questionnaires and specific criteria to determine their suitability. Most of the health questionnaires reviewed were used as screening measures for identifying both work and non-work-related psychological hazards. However, they were found to be limited in their application when considering all potential predictors of delayed return to work such as poor or stressful interactions with stakeholders, financial stress and the injured workers experience of the RTW process.
CONCLUSION:
Earlier identification of mental distress using an optimal MHSQ followed by appropriate intervention will reduce the risk of psychological injury becoming cumulative on a physical workplace injury. Without such complications, early return to work can be achieved with significant cost saving to the economy.
Introduction
Return to work (RTW) following an injury at the workplace should be a relatively straightforward process for the worker for the majority of physical injuries [1]. The longer an injured worker is absent from the workplace however, the less likely a sustainable RTW will occur [1–6]. While many injured workers recover from their injuries and RTW in a relatively systematic and predictable manner, others experience delays in their RTW schedule, with some never returning to their pre-injury duties [7–11]. Therefore, prevention of psychological distress following a physical workplace injury is an important priority for organisations and governments.
The economic cost associated with mental illness is significant. Even in a medium sized developed economy such as Australia, $51 billion was spent in 2018/19 to address issues associated with mental illness [23]. $11 billion of this total was directly borne by employers for workers’ compensation payouts, absenteeism and a reduction in productivity [24–26]. This is largely due to the unrecognised complexity of workplace injuries in the individual’s psychological wellbeing, particularly, loss of self-worth, uncertainty about the future, and the struggle to be supported adequately both psychologically and financially during the RTW process [12, 13].
The risk of a psychological injury becoming cumulative on a physical workplace injury increases when there is heightened anxiety around future pathways in the workplace [27]. The 2019/2020 Corona virus pandemic impact has further heightened that uncertainty none less in those injured in the workplace.
If left untreated, psychological distress over time can produce a diverse range of behavioural and cognitive changes including mood disorders (e.g. depression), anxiety disorders (e.g. posttraumatic stress), substance use disorders and even more protracted psychopathology [14–16]. Where workers’ long-term health issues are not treated, alcohol and other drug-related deaths and suicides have contributing to increasing mortality rates associated with work injuries [17]. Depression is particularly often associated with the aftermath of an occupational injury, with symptoms usually presenting within the first 12 months following a work-related musculoskeletal injury [16, 18–20].
In many developed economies such as the United States, United Kingdom, France, Norway, Denmark, Finland and Australia, Primary Care Physicians or General Practitioners usually provide the primary medical care for an injured worker [1, 151]. Primary Care Physicians manage the medical treatment of workers by delivering ongoing care and referrals to other health care practitioners (HCPs) to assist with their rehabilitation and RTW [1, 151].
While there is general consensus that appropriate psychological screening can detect potential complications encountered during the rehabilitation process [16], Primary Care Physicians throughout many countries often indicate that they do not have adequate time or resources to fully assess an injured workers’ physical injury and their mental health status [21, 21], 49].
To prevent mental distress following a physical workplace injury, it is essential that Primary Health Practitioners and other relevant HCPs should have access to an effective Mental Health Screening Questionnaire (MHSQ) that is able to detect potential psychosocial risk factors in order to facilitate appropriate interventions to ensure the ongoing wellbeing of the injured worker.
Despite the association of workplace injuries and mental health there is a paucity of research that explores: How and when mental health distress is triggered during the RTW process and; The effectiveness of any current Mental Health Questionnaire (MHQ) applied to detect the onset and underlying cause of mental distress encountered during the RTW process.
The aim of this review is to: Identify and provide an overview of the MHQs and other health questionnaires (HQs) used to assess mental wellbeing in injured workers following a physical injury at the workplace and; Assess the suitability and effectiveness of these questionnaires to detect early changes in mental wellbeing following a workplace injury that predict further psychopathology.
Preventive health screening has long been promoted as one of the most important health care strategies to facilitate early diagnosis and treatment, with the potential outcome as an improvement in the quality of life for those being screened [22, 23]. A study in 2005 suggested that when using a brief screening questionnaire, Primary Health Providers can recognise and manage common mental disorders, in addition may also influence a Primary Health Practitioners provision of care following the outcome of the screening questionnaire [24].
Methods
A scoping review methodology as described by Arksey & O’Malley [25] and Levac et al. [26] was adopted to explore the existing literature to identify the range of HQs used to assess mental health distress in injured workers following a workplace injury. This method allows for a rapid review and mapping of key concepts which underpin the research area to examine the extent, range and nature of research activity, identify gaps in all relevant literature, and summarise and disseminate research findings [16]. Our scoping review methodology follows a five (5) stage framework: (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data and (5) collating, summarising and reporting the results.
Identifying the research questions
This study extends on earlier research undertaken by the Chief Investigator investigating the role of HCP and Return to Work Coordinators in the rehabilitation of injured workers [1, 27]
The research questions below that guide this study evolved through a brainstorming session conducted by the research team and informed by the literature [104, 64]: What work related and other psychosocial risk factors have been identified that potentially compromise a worker’s mental wellbeing when rehabilitating from a physical injury? How does mental distress endured during the participation in a RTW process manifest in a physically injured worker? Has mental distress endured by the physically injured worker during a RTW process been shown to prolong or prevent their ultimate RTW? What screening tools are currently used to identify symptoms of mental distress in workers when participating in a RTW process? How effective are they? Where is the gap in the current knowledge, practice or evidence? Can current practice, knowledge or evidence be augmented or improved upon?
Identifying relevant articles and studies
A preliminary set of key words were developed, and an initial search conducted in Medline. The key words were then reviewed and used to search Medline, CINAHL, EMBASE and PsycINFO. The search strategy included a combination of Medical Subject Headings (MeSH) terms and key words for ‘workers’, ‘physical injuries’, ‘mental health’, return to work’ and ‘impact’ (see Appendix 1). The search was limited to articles published from 2000 to March 2020. Observational studies, including longitudinal cohort studies were included. Systematic reviews, conference abstracts, protocol papers and studies looking at pre-existing mental illness (including depression) before the physical injury occurrence as well as studies not available in English were excluded. Abstracts and proceedings from conferences and meetings, as well as other unpublished sources were excluded due to lack of peer review. Commentaries, review articles, editorials and letters to the editor were also excluded.
Literature search and article selection
Details of the search, screening and selection process are found in the flowchart of search results and screening (see Fig. 1).

Flowchart of search and screening results.
The initial database search identified 3168 articles. Suitable articles were subsequently identified through an independently conducted review by two authors [IW, JM]. Each author screened the title and abstract to determine which articles would be included for full review. Articles were excluded if they were duplicates; the injuries were not work related or; the study concerned pre-existing mental illness (such as depression) being investigated in isolation from physical injury. Disparities between review authors were resolved by discussion and if required a third reviewer was consulted (JBN). Title and abstract screening resulted in 2878 articles being excluded, leaving 276 for full text review.
A full text review to assess the eligibility of the 276 articles was then conducted by two researchers [JBN, JM] and on completion of a face to face review defence, 164 articles which utilised a MHQ (or a HQ with a significant mental health component) were retained for inclusion in this review. To assist in the analysis of the collated questionnaires, additional articles sourced from the literature were also referenced in the scoping review if they included an investigation of issues faced by a physically injured worker while engaged in a RTW process, including where involvement in the RTW process has been associated with any of the following: An impact on the worker’s mental health (including the development of chronic mental health conditions or substance abuse) or, A delayed or prolonged return to work or an abandonment of employment or, A deterioration in a work, social or family relationship or, A subsequent loss of identity or self-worth or an increase in feelings of hopelessness, grief, stigmatisation or financial loss or, An analysis of the success or otherwise of any intervention (eg. physiotherapy, pain management and/or counselling) employed to aid rehabilitation or, An analysis of a methodology employed by the Treating Medical Practitioners to identify deteriorating mental health with the injured worker.
In addition, reference lists of key journal articles were hand searched to source other appropriate research articles resulting in a further eight (8) articles to report on in the scoping review. Disparities between reviewers were resolved by discussion and if required a third reviewer was consulted [DJ].
All data extracted from the included studies was summarised by one of the authors [JM]. Two authors then collectively [IW, JBN] developed the data charting form to ascertain which variables to extract to answer the research questions. Using an iterative approach, the chart was updated continually by the authors. The extracted information included: study characteristics (study design, year published); participant characteristics (sociodemographic, nature of the work); what Health Questionnaire was used within and what study outcomes were noted (such as impact on return to work process, duration and the nature of the impact on subjects’ mental health).
Results
There were 164 studies identified from the literature where each of which had employed one or more of sixty-two (62) MHQ or HQ with a significant mental health component to augment the research being conducted. Analysis of these studies incorporating charted data and relevant criteria sourced from the literature is summarised in Appendix 2. Most of the studies sourced were from research institutions in Canada followed in decreasing numbers from the United States, Australia, Sweden, Norway, United Kingdom, The Netherlands, Denmark, Finland, Austria, Hong Kong, Switzerland, Japan, Finland, Korea, Taiwan, Germany, Malaysia, Iran and Spain.
The appraised range of 62 MHQ or HQ have been utilised within a wide range of study types including in seventy-two (72) prospective cohort studies, forty-nine (49) cross-sectional studies, nineteen (19) mixed methods study designs, fifteen (15) randomised control trials, five (5) retrospective cohort studies, four (4) longitudinal observational studies and one each in a non-randomised control trial and a pilot study. There was no discernible pattern of preference for a specific study type to favour the use of a particular MHQ or HQ.
In terms of participant characteristics, workers with (all cause, general) MSD were the most frequent studied subject cohort (42 studies); followed by workers with back pain (24 studies); workers on extended sick leave - all causes (17 studies); then workers with upper extremity pain (9 studies). Twelve (12) of the fifteen (15) randomised control trials sought to improve the outcome of rehabilitation through appropriate interventions designed to expedite the injured workers’ recuperation and/or return to work. While there were only 10 studies which listed a specific study attribute associated with an impact on the worker’s mental health (as indicated in the article’s descriptive “study population”), 142 studies considered mental health impacts as a secondary consideration associated with the specific topic of research being conducted. Of the 164 studies reviewed, 68 involved the active participation of a HCP independent of the team conducting the research.
The most significant work-related psychosocial risk factors highlighted within the literature that is linked to the efficacy of rehabilitation and which, if uncontrolled, could potentially undermine the physically injured worker’s return to work schedule includes:
How effective are the reviewed health questionnaires in identifying (and to potentially predict) critical aspects of mental health of workers or others suffering from a physical occupational injury?
From the full text review, sixty-two (62) diagnostic MHQs and HQs were identified. Each was appraised in terms of their attributes and ability to detect, predict or record impacts from the above psychosocial risk factors (subsequently summarised in Appendix 3).
As well as detecting symptoms of depression or anxiety, an effective MHSQ should also consider all work-related and non-work-related psychosocial risk factors that could impact on an injured worker’s mental health and wellbeing and delay their RTW. For example, while a recent study which trialled the ÖMPSQ-SF questionnaire and its value as a simple screening measure for workers at risk of a delayed RTW concluded that it is a suitable questionnaire for measuring a diverse range of work-related injuries, it does not notably account for all potential predictors which can impact on injured workers RTW [28]. Consulting table 3 it can be seen that the ÖMPSQ-SF satisfies only two (2) of the nine (9) criteria covered within this study.
In terms of questionnaire content, forty-one (41) HQs solicit for clinical symptoms of depression or anxiety, thirty (30) solicit in part for (or fear of) physical pain and sixteen (16) include soliciting for both clinical symptoms of depression or anxiety and pain. Twenty-one (21) include soliciting for the level of social support, sixteen (16) HQ include soliciting for the level of family support and twelve (12) HQ include soliciting for the level of support at work (be it supervisor or co-worker support). Six (6) HQ include soliciting for the impact of unreasonable work demands or timeframes (potentially indicating a mismatch of occupational task and health restriction where applied to a rehabilitation process), while four (4) HQ include soliciting for the impact of discrimination, harassment, bullying or stigma. No HQ included consideration of the impact of poor or stressful interaction with healthcare providers or financial stress on the injured worker’s return to work progress.
The HQs that cover a majority of the above work and non-work-related psychosocial risk factors are the Return to work Obstacles and Coping Efficacy –Musculoskeletal Disorder questionnaire [ROSES-MSD] and the Obstacles to Return-to-Work Questionnaire –ORQ, both of which cover seven of the nine work and non-work-related psychosocial risk factors assessed in this study.
Return to work obstacles and self efficacy scale (ROSES-MSD)
The latest Return-to-Work Obstacles and Self-Efficacy Scale (ROSES-MSD) is a 46-item self-reported inventory spread out over 10 conceptual dimensions. The inventory comprises the following dimensions [29]: Fears of a relapse – (4) Questions:- Q1, 11, 24, 32 Cognitive difficulties – (3) Questions:-Q 2, 12, 39 Medication-related difficulties – (3) Questions:- Q3, 13, 29 Job demands – (7) Questions:- Q4, 14, 22, 25, 28, 38, 45 Feeling of organizational injustice – (4) Questions:-Q 5, 15, 30, 34 Difficult relation – immediate supervisor – (7) Questions:- Q6, 16, 21, 31, 36, 41, 44 Difficult relations – co-workers – (7) Questions:- Q7, 19, 23, 27, 33, 43, 46 Difficult relations – insurance company (4) Questions: - Q8, 17, 35, 40 Difficult work/life balance – (4) Questions:- Q9, 18, 37, 42 Loss of motivation to return to work – (3) Questions:- Q10, 20, 26
Obstacles to return-to-work questionnaire (ORQ)
The Obstacles to Return-to-Work Questionnaire (ORQ) is a 55-item self-reported inventory comprising the following nine (9) subscales [30]: Depression – (4) Questions Pain intensity – (4) Questions Difficulties at work return – (8) Questions Physical workload & harmfulness – (8) Questions Social support at work – (6) Questions Worry due to sick leave – (3) Questions Work satisfaction – (9) Questions Family situation and support– (7) Questions Perceived prognosis of work return – (6) Questions.
Both ROSES-MSD and ORQ lack the ability to solicit and assess the impact of poor or stressful interaction with healthcare providers and financial stress on the injured worker’s mental health with both psychosocial risk factors potentially prolonging or preventing a timely RTW.
Without consideration of the full range and their accumulated impact on a physically injured person’s mental wellbeing and RTW progress, the range of articles assessed, including those utilising HQs have been found limited in their further application to assist in improving the efficacy of the return to work process.
A majority of the sixty (62) HQs sourced from the review and represented in Appendix 3 could be applied during an RTW review meeting to determine the presence of certain elements and symptoms associated with the worker’s mental health. However, no one HQ is structured to identify or solicit for all of the psychosocial risk factors and obstacles potentially associated with their readiness to RTW. There is also little evidence to indicate that any are structured to chronologically record the point(s) within the RTW program where mental distress has occurred.
Outside of use by academics with specific arms-length research questions, no study examined the use and efficacy of the HQ to improve the HCP or injured party’s experience of the RTW process. Moreover, while many of the assessed HQ have been utilised in research focussed questions on specific aspects of the RTW process, there is no evidence that the efficacy of using a HQ in the context of participation within the RTW program has been investigated from the perspective of the primary health care providers as the coordinating HCP.
Discussion
This review aimed to identify and provide an overview of the MHQs and other health questionnaires (HQs) used to assess mental wellbeing in injured workers following a physical injury at the workplace. Furthermore, it aimed to assess the suitability and effectiveness of these questionnaires to detect early changes in mental wellbeing following a workplace injury that predict further psychopathology. In seeking these aims, the review found the questionnaires limited in their application with improving the effectiveness of the return to work process.
Rehabilitation, associated with participation within a return to work program, is utilised within many countries and industry sectors to facilitate workers returning to their pre-injury duties, following a workplace injury. However, workers who have been injured can experience hostility and frustration with the workers’ compensation system and obstacles within the rehabilitation program can be detrimental to their timely RTW [25]. This is possibly due to a disparity between the needs of the returnee and the needs of compensation system with evidence indicating that timely RTW can be less reliant on physical functioning and more on the influence of psychosocial risk factors [31]. We have compiled a comprehensive manifest of these factors (see Table 1).
Psychosocial risk factors potentially adversely impacting on return to work
Psychosocial risk factors potentially adversely impacting on return to work
Both positive and adverse impacts on mental health outcomes in injured persons participating in a RTW process were revealed in this review. Importantly, this review highlighted anxiety and depression developing from anticipation of a RTW after a physical injury which was found to be closely associated with a perceived lack of control over potential obstacles that may be encountered in the work environment [13, 31–34]. Fear avoidance belief significantly impacted on the resumption of normal work duties. Reducing the effectiveness of rehabilitation interventions and ultimately prolonging or preventing a RTW, some studies identified the fear of pain and its consequences pre-empted catastrophizing thoughts and resulted in avoidance of activities believed to be harmful or that aggravated pain, [4, 35–42]. Several studies have utilised the Fear-Avoidance Components Scale (FACS) to help HCP to better identify and address fear-avoidance related barriers to recovery, and to measure treatment responsiveness of related symptoms [43–46]. Workers recovering from musculoskeletal injuries also have a demonstrably reduced expectancy for recovery and a lower likelihood that they will participate fully in treatments conducive to a timely RTW [47].
A continuing concern for injured workers is the emotional stress and frustration encountered with the RTW process and the workers’ compensation scheme [1, 48–50]. In fact, delays in the RTW process often leave injured workers with a growing sense of hopelessness, grief and stigmatisation and a loss of confidence, self-worth and financial support [39].
Additionally, mental distress for an injured worker can also be associated with negative interactions with the employer, the insurer, family members or work associates during the RTW process [1, 51–53]. Moreover, the procedural complexities inherent within the workers compensation system also act as an obstacle to a timely RTW [1, 54].
Workers with physical occupational injuries throughout the developed world experience these and other obstacles including mental distress encountered during the rehabilitation process and subsequent attempts to return to work [16, 187]. Encountering such obstacles can diminish an injured workers’ perceived control over their progress [66] and detrimentally affect their social, work and family relationships [18, 53]. The worker’s self-efficacy beliefs and confidence that these obstacles can be overcome may significantly influence the speed and ultimately the success of their rehabilitation [29]. If these cumulative factors persist or remain unrecognised and untreated, the resulting impact on their mental health can undermine injured workers’ timely rehabilitation and RTW [12, 53].
While desired health and functional capacity outcomes are not always achieved during the RTW process, there is significant evidence that timely rehabilitation and the earliest possible RTW are associated with beneficial mental health outcomes for workers with physical injuries [21, 55–58].
Where the HCP recommends interventions to expedite an injured worker’s RTW, the injured worker should have confidence that they are acting in their best interest. To obtain the best possible therapeutic outcome, the ongoing relationship between the HCP and injured worker should be underpinned with trust, respect and consistent agreement on, and collaboration towards completion of tasks required to reach the goals of treatment [21, 59]. In terms of a general response to therapeutic treatment, the placebo response has been extensively studied and consistently shown to result in beneficial outcomes with the quality of the HCP-recipient level of established trust significantly contributing to these outcomes [60]. Positive treatment outcomes in part due to the placebo response have also been associated with a range of interventions facilitated by HCPs designed to treat chronic lower back pain [61].
Additionally, persons experiencing mental distress including panic disorders or mild to moderate depression, or generalized anxiety disorder experience significant relief and a greater sense of control over distressing symptoms, regardless of the treatment interventions proposed or ultimately implemented, merely through regular, quality interaction with their treating HCP [60].
An injured worker in the process of rehabilitation and return to work is best supported by a person-centred approach in which the development of a trusting therapeutic relationship that promotes authenticity and unconditional positive regard, provides the best environment for therapeutic success [62, 63]. For example, where the HCP has been trained in improved communication, consultation and rapport including practicing appropriate eye contact and normalizing difficult experiences related by those under care, less anxiety and depression were present in those care recipients, over the period of treatment [4, 64].
Primary Health Care Practitioners are critical HCPs in the rehabilitation process and the injured worker’s ultimate return to work. When the Primary Health Care Practitioner provides the injured worker with relevant information about their health and rehabilitation possibilities and projects an empathic attitude toward the patient’s plight, better rehabilitation and RTW outcomes are achieved [65].
Timely mental health screening has also been demonstrated to enable the treating HCP to better identify workers [who have been physically injured] with underlying or concomitant psychological distress / disorders and to refer them for further investigation, diagnosis and appropriate tailored intervention / treatment with a psychologist or counsellor [56, 66]. This and/or other treatment options such as the application of cognitive–behavioural therapy in which problem-solving skills are taught have previously been shown to reduce psychological distress impacting the worker [2, 67–69].
There is clear evidence which supports early screening and interventional treatment of injured workers highlighting the positive effects on their physical and mental health and RTW efficacy.
However, there is a paucity in the literature on primary health care providers and other HCPs regarding their access to, or their use of a MHSQ which may assist with early detection of potential psychosocial risk factors which can impact an injured workers mental health and wellbeing following a workplace injury. Additionally, there is little supporting evidence to suggest the existence of an appropriate MHSQ for primary health care providers and HCPs that could identify all potential predictors of psychological distress for a worker following a workplace injury.
Ideally such a screening tool would, even on one application assist primary health care providers and HCPs determine the onset of psychological distress (post physical injury) during the return to work process and facilitate early referrals and interventions to support an injured worker during their rehabilitation. Subjective reporting of changes in mental health status could alert the practitioner by using the same instrument at different times and stages of the RTW process.
We all exist in an age of heightened anxiety from increased biological and psychosocial stresses including work uncertainty anxiety around future pathways now threatened by the Coronavirus pandemic. Therefore, prevention of psychological distress following a physical workplace injury should be treated as a priority.
Further research and recommendations to address the gaps in current practice
How and when and at what cost mental health distress is encountered during the rehabilitation and RTW process needs to be addressed in subsequent research.
It is essential that a suitable MHSQ be developed or refined from existing questionnaires and trialled to achieve the most suitable tool to assist primary health care providers, other HCPs and researchers. This will assist in screening for and identifying when and at what stage the onset of psychological distress (post physical injury) has occurred during the return to work program. An additional provision within the MHSQ to prompt the treating medical practitioner to consider employing an intervention to arrest deteriorating mental health would be beneficial also to the ongoing wellbeing of the injured worker.
The optimised MHSQ should also be capable of being completed by the HCP in consultation with, or in part, independently by the injured party and facilitate the identification of the broadest possible range of psychosocial risk factors that are potentially impacting on the efficacy of the return to work process.
Such screening that is applicable and effective, and useful to researchers, would also need to be concise enough to be useful to the HCP in a clinical setting. Excessive alcohol consumption is associated with deteriorating mental health in many injured workers [17, 70–74] and is associated with prolonged rehabilitation times [8] and/or termination of employment [43]. Therefore, we would recommend that the Alcohol Use Disorders Identification Test (AUDIT; a 10-item screening tool developed by the World Health Organization) be incorporated within the final screening to assess hazardous and harmful consumption of alcohol over time.
An optimum and timely response to address the impact of psychosocial risk factors on the mental wellbeing of injured workers navigating the RTW process may ultimately yield a more expeditious return to work while contributing to significant fiscal savings within the national workers’ compensation system.
Finally, contemporary research now identifies that growth out of adversity is possible with the right support, highlighting the gains to be made both personally and in the workplace from a focus on the holistic approach to recovery following a workplace injury which in turn can be to the benefit of the organisation. [75].
Conclusion
A broad range of health questionnaires (HQ) were sourced from the literature and reviewed for this scoping review. Many have been used by academics to screen and identify a limited range of both work and non-work-related psychosocial risk factors to investigate specific arms-length research questions with some focusing on specific aspects of the RTW process. Individually they were all found to be limited in their application when considering all potential predictors of delayed RTW.
Earlier identification of mental distress using an optimal mental health screening questionnaire (MHSQ) followed by appropriate intervention will reduce the risk of psychological injury becoming cumulative on a physical workplace injury. Without such complications, anticipated long term outcomes resulting from the effective application of MHSQ include an improvement in the wellbeing and mental health of persons completing the workers’ compensation process, a shortening of the recovery and rehabilitation times of injured persons, and given the positive impact of the above, a significant decrease in the overall financial burden on the national economy.
