Employment barriers questionnaire: Development and determination of its reliability and validity

BACKGROUND

The high unemployment rate among people with disabilities (PWDs) can be attributed to barriers found in the work environment and demands of the job itself. Given the lack of comprehensive tools to identify these barriers, we developed the Employment Barriers Questionnaire (EBQ).

OBJECTIVE

The objective of this study was to develop and examine the EBQ's reliability and validity for detecting employment barriers and possible modifications to overcome them.

METHODS

Two stages were conducted: stage I was a cross-sectional design. Stage II included a cross-sectional and prospective design. Thirty-nine people with physical disabilities (mean age 47.21±10.78 years) were recruited, 51% of which were employed during data collection. During stage I, we developed a first version of the EBQ (EBQ.I) and evaluated its internal reliability. The EBQ.I was filled twice, one week apart to assess test-re-test reliability. Predictive validity was tested using a regression model to predict the employment status of stage II based on EBQ.I's results from stage I. In stage II, we generated a second version (EBQ.II) and tested its internal-reliability and known-groups validity, by comparing the EBQ.II's results between employed and unemployed subjects.

RESULTS

The results showed that the EBQ.II has a high internal-reliability (α= 0.79-0.97) and a medium-large known-groups validity (-3.95≤Z≤-2.26, p < 0.05). Additionally, the EBQ.I has a high test re-test reliability (ICC = 0.85-0.94, p < 0.001) and predictive validity (β= 0.861, p = 0.033).

CONCLUSION

This study has illustrated that the EBQ.II is a unique, reliable and valid tool for identifying employment barriers and modifications to address them, expected to improve vocational rehabilitation efforts.

Traumatic brain injury as a chronic disease: insights from the United States Traumatic Brain Injury Model Systems Research Program

Traumatic brain injury (TBI) is a global health priority, associated with substantial burden. Historically conceptualised as an injury event with finite recovery, TBI is now recognised as a chronic condition that can affect multiple domains of health and function, some of which might deteriorate over time. Many people who have had a TBI remain moderately to severely disabled at 5 years, are rehospitalised up to 10 years post-injury, and have a reduced lifespan relative to the general population. Understanding TBI as a chronic disease process can be highly informative for optimising care, which has traditionally focused on acute care. Chronic brain injury care models must be informed by a holistic understanding of long-term outcomes and the factors that can affect how care needs evolve over time. The United States Traumatic Brain Injury Model Systems of Care follows up individuals with moderate-to-severe TBI for over 30 years, allowing characterisation of the chronic (2-30 years or more post injury) functional, cognitive, behavioural, and social sequelae experienced by individuals who have had a moderate-to-severe TBI and the implications for their health and quality of life. Older age, social determinants of health, and lower acute functional status are associated with post-recovery deterioration, while younger age and greater functional independence are associated with risky health behaviours, including substance misuse and re-injury. Systematically collected data on long-term outcomes across multiple domains of health and function are needed worldwide to inform the development of models for chronic disease management, including the proactive surveillance of commonly experienced health and functional challenges.

Cognitive Dependence in Physically Independent Patients at Discharge From Acute Traumatic Brain Injury Rehabilitation

OBJECTIVE

To determine the incidence of cognitive dependence in adults who are physically independent at discharge from acute traumatic brain injury (TBI) rehabilitation.

DESIGN

Analysis of historical clinical and demographic data obtained from inpatient stay.

SETTING

Inpatient rehabilitation unit in a large, metropolitan university hospital.

PARTICIPANTS

Adult inpatients with moderate to severe TBI (N=226) who were physically independent at discharge from acute rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

FIM Motor and Cognitive subscales, discharge destination, and care plan.

RESULTS

Approximately 69% (n=155) of the physically independent inpatients were cognitively dependent at discharge from acute rehabilitation, with the highest proportions of dependence found in the domains of problem solving and memory. Most (82.6%; n=128) of these physically independent, yet cognitively dependent, patients were discharged home. Of those discharged home, 82% (n=105) were discharged to the care of family members, and 11% (n=15) were discharged home alone. Patients from racial and ethnic minority backgrounds were significantly more likely than White patients to be discharged while cognitively dependent.

CONCLUSIONS

The majority of physically independent patients with TBI were cognitively dependent at the time of discharge from acute inpatient rehabilitation. Further research is needed to understand the effect of cognitive dependence on caregiver stress and strain and the disproportionate burden on racial and ethnic minority patients and families. Given the potential functional and safety limitations imposed by cognitive deficits, health care policy and practice should facilitate delivery of cognitive rehabilitation services in acute TBI rehabilitation.

Factors associated with sustaining work after an acquired brain injury: a scoping review

PURPOSE

Maintaining work in the long term represents a major challenge for people with acquired brain injury (ABI) as evidenced by a high rate of premature labour market dropouts. The present study aimed to compile factors associated with working in the long term after sustaining an ABI.

MATERIALS AND METHODS

We carried out a scoping review synthesizing quantitative and qualitative research conducted between 2000 and 2021. Databases searched comprised PubMed, CINAHL Complete, PsycINFO, Scopus, and Web of Science.

RESULTS

Ten quantitative and nine qualitative studies were included, all but one from high-resource countries. Quantitative research predominantly comprised longitudinal follow-ups on individuals' work status several years post ABI onset, showing an effect of injury-related and sociodemographic factors. Qualitative studies mostly dealt with work maintenance and revealed a key role of cognitive difficulties, psychological personal factors (e.g., adequate coping strategies) and environmental factors (e.g., flexible work schedules, supportive colleagues).

CONCLUSIONS

The factors identified in our review should receive particular attention in vocational integration and job retention programs to support work participation of people with ABI in the long term. There is a need for measures that regularly monitor and promote a good match between individuals and their work environment.Implications for RehabilitationPeople with acquired brain injury (ABI) often have long-lasting and invisible injury-related difficulties that hamper their labour market participation.Factors identified as positively associated with working in the long term, such as coping strategies and self-awareness, should be strengthened.Future interventions should educate affected persons, employers and health care professionals about long-lasting injury-related difficulties and promote a supportive work environment for people with ABI.Prolonged availability of vocational services could be beneficial for supporting work maintenance of people with ABI.

Predictors of return to work after moderate-to-severe traumatic brain injury: a systematic review of current literature and recommendations for future research

PURPOSE

To identify factors associated with employment between six months and five years after traumatic brain injury (TBI).

METHODS

Using a predefined search algorithm, four electronic databases were searched for literature published between 2014 and the first half of April 2021 containing predictors of employment outcome. Data were selected in accordance with the PRISMA flow and the whole process was conducted by two reviewers who had to attain a consensus. The study results were discussed with an expert panel, in order to provide guidance for future research on this topic.

RESULTS

This review found clear evidence for employment status at time of injury, occupation at time of injury, Glasgow Coma Scale, length of stay, disability level and primary payer to be predictors of return to work after TBI.

CONCLUSIONS

More literature investigating in depth the functioning and environmental factors is required for further improvement of predictions, rehabilitation and policy.Implications for rehabilitationThis study identifies predictors of return to work in TBI patients, which can be used to identify patients with high risk early in the recovery process.Current literature shows difficulties with general functioning are a barrier for return to work, but gives no indication about effective therapeutic interventions.More knowledge about modifiable factors is desirable to improve rehabilitation and, thereby, employment outcomes after TBI.
