Vocational rehabilitation evaluation and the International Classification of Functioning, Disability, and Health (ICF)

Translation and cross-cultural adaptation of the Work Rehabilitation Questionnaire (WORQ) into Danish

Purpose

This study aimed to translate and cross-culturally adapt the work rehabilitation questionnaire (WORQ) into Danish to examine the internal consistency and test-retest reliability of the Danish WORQ and, second, to test the feasibility of WORQ in the Danish context of vocational rehabilitation.

Methods

The translation was performed in a dual-panel approach. The panel consisted of a bilingual physician, a university student in psychology, a layperson, a specialist in social work and rehabilitation, and a professor in social medicine. The international classification of functioning, disability, and health (ICF) codes were cross-evaluated to secure that there was a high level of agreement of ICF codes for each specific WORQ item in the Danish and English version. The content validity was evaluated by the clinical physicians at an outpatient clinic in social medicine and by the case managers at a municipality job center. Data for the examination of the internal consistency and test-retest reliability were collected at the Holbæk municipality from citizens in the working age. The test-retest took place 14 days apart. The internal consistency and test-retest reliability were tested conducting Cronbach's alpha, intraclass correlation, and Spearman's correlation analyses.

Results

The panel experienced only minor challenges in the translation process, leading to minor modifications. The cross-evaluation of coding in the Danish WORQ compared with the initial English version only found small deviations, while the remaining coding agreed between the initial English and the Danish items. The panel argued to add sub-codes to culturally adapt to the transportation forms generally used in Denmark. The general perception among the participating patients and citizens at the job center as well as the clinical physicians and case managers was that the WORQ was easy, understandable, and meaningful.

Conclusions

This study showed that the Danish WORQ have a high content validity and usability. Nonetheless, the Danish WORQ needs to be validated against well-acknowledged tools for assessing functional ability specific to work and in general.

Cross-Cultural Adaptation, Reliability, and Validity of a Turkish Version of the Work Rehabilitation Questionnaire (WORQ-Turkish)

Purpose The Work Rehabilitation Questionnaire (WORQ) is an instrument based on the International Classification of Functioning Vocational rehabilitation core set. The aim of this study was to analyze the validity, reliability and cross-cultural adaptation of the WORQ to Turkish and evaluate its psychometric properties. Methods The cross-cultural adaptation and translation procedures were conducted following Beaton's guidelines. The test-re-test reliability was examined by Spearman Brown Coefficient (split half analysis), internal consistency was examined by Cronbach's alpha. Criterion related validity of the WORQ was determined by Beck Depression Inventory using Pearson correlation coefficient and known group differences regarding age, gender, work and educational levels using one-way ANOVA and t test. Construct validity was examined by confirmatory factor analysis using AMOS. Results Two hundred and fifty-seven participants with disabilities were included to the study from seven different provinces of Turkey. The WORQ-Turkish showed excellent internal consistency (0.906), good test-retest reliability (0.811), and good construct validity (good model fit indices). Criterion related validity analysis showed medium correlations between WORQ and Beck Depression Inventory (p < 0.001), however there were no statistical significant differences regarding known group parameters (p > 0.05). Conclusions In this study, the cross-cultural adaptation, and validity and reliability of WORQ-Turkish self-reported version were examined and the results indicated that WORQ-Turkish was a valid and reliable scale for analyzing vocational rehabilitation process of people with disabilities.

Predicting Recovery in Individuals With Serious Mental Illness: Expanding the International Classification of Functioning, Disability, and Health (ICF) Framework

People with psychiatric disabilities experience significant impairment in fulfilling major life roles due to the severity of their mental illness. Recovery for people with serious mental illness (SMI) can be a long, arduous process, impacted by various biological, functional, sociological, and psychological factors which can present as barriers and/or facilitators. The purposes of this study were to: (a) investigate the International Classification of Functioning, Disability, and Health (ICF) framework’s ability to predict recovery in adults with SMI and (b) determine to what extent the ICF constructs in the empirical model explain the variance in recovery. Participants ( N = 192) completed a sociodemographic questionnaire and various measures representing all predictor and outcome variables. Results from hierarchical regression analysis with six sets of predictors entered sequentially (1 = personal factors-demographics, 2 = body functions-mental, 3 = activity-capacity, 4 = environmental factors, 5 = personal factors-characteristics, and 6 = participation-performance) accounted for 75% (large effect) of the variance in recovery. Controlling for all factors, by order of salience, higher levels of significant other support, education, executive function impairment, and social self-efficacy; primary, non-bipolar SMI diagnosis; greater resilience; lower levels of explicit memory-health impairment, affective self-stigma, and cognitive self-stigma; being younger; fewer self-care limitations; less severe psychiatric symptoms; and being unemployed and unmarried were found to significantly predict recovery. Findings support the validation of the ICF framework as a biopsychosocial recovery model and the use of this model in the development of effective recovery-oriented interventions for adults with SMI. Clinical and research implications are discussed.

Disability and functioning assessment of women with RSI/WRMSDs: the use of the ICF checklist

Background:

Comprehensive approaches using the International Classification of Functioning, Disability and Health (ICF) Checklist have been adopted to give more visibility to demands related to specific health situations.

Objective:

To analyze the incapacity and functioning associated with activity/participation and environmental factors of female workers with repetitive strain injury/work-related musculoskeletal disorders (RSI/WRMSDs) using workers’ narratives, ICF codes and the RSI/WRMSDs Checklist developed as a part of the present research project.

Methods:

A qualitative analysis of in-depth interviews with 15 female workers diagnosed with RSI/WRMSDs was completed. Functioning and disability were assessed by linking ICF codes identified in the participants’ narratives to those included in the RSI/WRMSDs Checklist.

Results:

Fifty-three of 60 ICF codes included in the RSI/WRMSDs Checklist were detected in the participants’ narratives. Related to activity/participation, 26 codes were identified and 27 related to environmental factors.

Conclusion:

These results highlight the significance of the RSI/WMSDs Checklist to detect clinical and social problems experienced by workers during the rehabilitation and return-to-work process. They also reinforce the relevance of expanding the application of the checklist to male and female workers with RSI/WRMSDs undergoing rehabilitation to attain other levels of validation.

International Classification of Functioning, Disability and Health in Vocational Rehabilitation: A Scoping Review of the State of the Field

Purpose The purposes of this study were to provide an outline of the existing literature on operationalization of the International Classification of Functioning, Disability and Health (ICF) within vocational rehabilitation (VR) and to explore the ICF utility within VR. Methods The process was undertaken in five stages according to a framework of scoping review. Screening and extraction of data were done by two independent reviewers, and data was summarized according to content analysis. Results Fifty papers (25 qualitative and 25 quantitative) were included. The operationalization of the ICF was described in four different ways: In total 18 (36%) papers described use of the ICF for structuring information, 8 (15%) for linking information to ICF, 12 (24%) for analysis of results, and 12 (24%) for development of a model. In total 15 (29%) papers described VR interventions involving stakeholders, whereas 32 (62%) were reviews. Forty of the papers described all the ICF components. Conclusions The review revealed use of the ICF within the field VR in 50 papers, and in various settings. The ICF framework was most often operationalized for structuring or linking information of functioning. A majority of papers were reviews and involved researchers only, whereas different stakeholders and VR professionals were involved in the interventions. In 40 papers all the ICF components were described, and the ICF was considered a useful tool to inform the VR professionals´ assessment of functioning. However, more research within VR is needed to standardize and ease the use of the ICF.

Cross-Cultural Adaptation of the Work Rehabilitation Questionnaire (WORQ) to French: A Valid and Reliable Instrument to Assess Work Functioning

Purpose The Work Rehabilitation Questionnaire (WORQ) is a patient-reported instrument to assess work related functioning in vocational rehabilitation (VR) and work, based on the International Classification of Functioning, Disability and Health (ICF) core set for VR. The objective of this study was to cross-culturally adapt WORQ to French and to evaluate its psychometric properties. Methods The cross-cultural adaptation followed a dual-panel approach. Psychometrics was examined in one VR-centre in the French speaking part of Switzerland. Test-retest reliability was analyzed with intraclass correlation coefficient (ICC), internal consistency was assessed with Cronbach's alpha. Construct validity was determined by convergence to the self-reported general functioning scale and the Hospital Anxiety and Depression Scales (HADS). The association of patient's return-to-work expectation within 6-months and having a case manager was examined. The usability of WORQ-French was tested in 10 VR patients. Results Eighty-nine patients with musculoskeletal injuries were included. WORQ-French showed excellent internal consistency (0.968) and a high test-retest reliability (0.935). WORQ-French was positively associated with self-reported general functioning (r = 0.662) and both HADS scales (r = 0.56-0.57). Neither the patient's return-to-work expectation nor having a case manager were significantly correlated with WORQ-French. Usability in terms of understandability of questions and response options was found to be good. Seven patients rated the length of WORQ-French as good, while two found the instrument a little too long and one found it too long. Conclusions WORQ French is a valid, reliable, and easy to administer instrument to assess self-reported work functioning given our study setting and sample characteristics.

An examination of concepts in vocational rehabilitation that could not be linked to the ICF based on an analysis of secondary data

BACKGROUND

In the last few years the International Classification of Functioning, Disability and Health (ICF) has become a widely known and useful reference classification in vocational rehabilitation. It would be equally important to know which aspects of work-related health information cannot be assigned to distinct ICF categories.

OBJECTIVE

The objective of this study is to examine the concepts derived from three studies conducted within the ICF Core Set for vocational rehabilitation project, which could not be linked to distinct ICF codes in order to complement the current understanding of functioning in vocational rehabilitation.

METHODS

Secondary data analysis of the concepts from the systematic literature review, expert survey and patient focus group study of the ICF Core Set for vocational rehabilitation project that were marked as nd = not definable, nc = not covered or pf = personal factor. Nd-concepts were assigned to the biopsychosocial model of the ICF; additional ICF categories were formulated where needed. Nc-concepts were grouped into common themes not covered by the ICF. Pf-categories were linked to a proposed personal factors classification.

RESULTS

1093 nd-concepts were matched to overarching terms in the ICF, and "other specified"-categories were detailed. 1924 pf-concepts were linked to 31 second level categories of a proposed personal factors classification. 441 nc-concepts were grouped into six themes including the concept of well-being and attributes related to processes and time.

CONCLUSIONS

With concepts that emerged from the secondary analysis of data gathered during the vocational rehabilitation ICF Core Set project, we have enriched the ICF model with constructs specific to vocational rehabilitation. However, additional research is needed to further explore personal factors specific to vocational rehabilitation. The influence of themes complementary to the ICF such as well-being and quality of life on return-to-work should be further investigated.

Validation of the Comprehensive ICF Core Set for Vocational Rehabilitation From the Perspective of Physical Therapists: International Delphi Survey

BACKGROUND

The Comprehensive ICF Core Set for vocational rehabilitation (VR) is a list of essential categories on functioning based on the World Health Organization (WHO) International Classification of Functioning, Disability and Health (ICF), which describes a standard for interdisciplinary assessment, documentation, and communication in VR.

OBJECTIVE

The aim of this study was to examine the content validity of the Comprehensive ICF Core Set for VR from the perspective of physical therapists.

DESIGN

A 3-round email survey was performed using the Delphi method.

METHODS

A convenience sample of international physical therapists working in VR with work experience of ≥2 years were asked to identify aspects they consider as relevant when evaluating or treating clients in VR. Responses were linked to the ICF categories and compared with the Comprehensive ICF Core Set for VR.

RESULTS

Sixty-two physical therapists from all 6 WHO world regions responded with 3,917 statements that were subsequently linked to 338 ICF categories. Fifteen (17%) of the 90 categories in the Comprehensive ICF Core Set for VR were confirmed by the physical therapists in the sample. Twenty-two additional ICF categories were identified that were not included in the Comprehensive ICF Core Set for VR.

LIMITATIONS

Vocational rehabilitation in physical therapy is not well defined in every country and might have resulted in the small sample size. Therefore, the results cannot be generalized to all physical therapists practicing in VR.

CONCLUSION

The content validity of the ICF Core Set for VR is insufficient from solely a physical therapist perspective. The results of this study could be used to define a physical therapy-specific set of ICF categories to develop and guide physical therapist clinical practice in VR.

Outcomes of return-to-work after stroke rehabilitation: A systematic review

Introduction

The purpose of this systematic review was to identify the outcomes of return-to-work for stroke survivors of working age after conventional stroke rehabilitation or vocational rehabilitation.

Method

Searches were performed using three electronic databases for literature published in English in the 10-year period 2004–2014 which included a population of working age stroke survivors who had previously participated in conventional or vocational rehabilitation, and which presented the outcomes of return-to-work.

Findings

The literature search yielded 10 studies that satisfied our selection criteria. Three studies involved vocational rehabilitation. Studies illustrated and compared the vocational status at or among different stages of ‘pre-stroke’, ‘post-stroke and before rehabilitation discharge’, ‘rehabilitation discharge’ and ‘follow-up’. The employment rate at follow-up ranged from 7% to 81.1%.

Conclusion

Methodological variations accounted for the wide range of return-to-work rates. There was limited evidence to support the conclusion that rehabilitation increases return-to-work rates for stroke survivors of working age, but recent studies showed that improvements in fatigue and cognitive function after stroke rehabilitation were related to good return-to-work outcomes. Either specialised vocational rehabilitation, conventional stroke rehabilitation or their combination is needed to increase return-to-work rates and improve the quality of life for stroke survivors of working age.

Systematic Literature Review on ICF From 2001 to 2013 in the Nordic Countries Focusing on Clinical and Rehabilitation Context

We present a systematic review on International Classification of Functioning, Disability and Health (ICF) used in the Nordic countries from 2001 through 2013, describing and quantifying the development in utilization of ICF, and describe the extent to which the different components of the ICF have been used. A search was conducted in EMBASE, MEDLINE and PsycInfo. Papers from Nordic countries were included if ICF was mentioned in title or abstract. Papers were assigned to one of eight categories covering the wide rehabilitation area; furthermore, area of focus was assigned. Use of ICF components and intervention were coded in papers categorized as "clinical and/or rehabilitation contexts" or "non-clinical contexts". One hundred seventy papers were included, of these 99 papers were from the categories "clinical and/or rehabilitation contexts" or "non-clinical contexts". Forty-two percent of the 170 included papers were published in the period 2011 - 2013. There was an increase in ICF-relevant papers from 2001 to 2013, especially in the categories "clinical and/or rehabilitation contexts" and "non-clinical contexts". The most represented focus areas were neurology, musculoskeletal, and work-related areas. All five or at least four ICF components were mentioned in the results or discussions in most papers, and activity was most frequently mentioned.

Problem-based self-care groups versus cognitive behavioural therapy for persons on sick leave due to common mental disorders: a randomised controlled study

PURPOSE

To evaluate the interventional capacity of problem based method groups (PBM) regarding mental health and work ability compared to cognitive behavioural therapy (CBT) for persons on sick leave due to common mental disorders.

METHODS

In a randomised controlled design the experimental group received PBM and the control group received CBT. Outcomes were measured by the Hospital Anxiety and Depression Scale (HADS), the Stress and Crisis Inventory 93 (SCI-93) and the Dialogue about Working Ability instrument (DOA).

RESULTS

Twenty-two participants in the PBM group and 28 in the CBT group completed intervention. Both groups showed significant lower scores on the two HADS subscales. Regarding stress the PBM group showed significant decrease in one (out of three) subscales of SCI-93. The CBT group showed significant decrease on all subscales of SCI-93. Regarding work ability the PBM group showed significant higher scores on one of five subscales of DOA. The CBT group showed significant higher scores on four of five subscales of DOA. Between groups there were significant differences to the favour of CBT on one of two subscales of HADS, all three subscales of SCI-93 and on two of the five subscales of DOA.

CONCLUSION

PBM seem to be able to reduce anxiety- and depression symptoms. CBT showed to be superior to PBM in reducing symptoms in all aspects of mental health, except for anxiety, in which they seem equally effective. Regarding work ability CBT showed to be superior, with significant effect on more aspects compared to PBM.

Work Rehabilitation Questionnaire (WORQ): development and preliminary psychometric evidence of an ICF-based questionnaire for vocational rehabilitation

PURPOSE

The International Classification of Functioning, Disability and Health (ICF) has proven to be a valuable framework for vocational rehabilitation (VR). No reliable and valid ICF-based instruments to capture work functioning is known, hence, the aims of this study were: (1) to outline the process for developing an ICF-based questionnaire, the Work Rehabilitation Questionnaire (WORQ) to assess functioning in VR and (2) to report preliminary psychometric evidence.

METHODS

ICF categories were selected from the ICF Core Sets for VR using explorative Rasch-analysis and VR literature review. Questions were worded to assess identified ICF categories. WORQ was translated from English to German. Psychometrics for the German version of WORQ was examined in one VR centre in Switzerland.

RESULTS

44 ICF categories were selected which resulted in 36 questions related to functioning. The psychometric evaluation of WORQ showed high test-retest reliability (Spearman correlation 0.79) (n = 53) and good internal consistency (Cronbachs Alpha 0.88) (n = 74) WORQ showed moderate correlation with Beck Depression Inventory II (Spearman correlation 0.511) and low correlation (Spearman correlation -0.353) with SF-36.

CONCLUSIONS

WORQ appears to be a reliable, ICF-based questionnaire to evaluate functioning in VR, easy to administer by health or vocational professionals. The additional information gained when using WORQ would contribute to improving interdisciplinary understanding of the patient's situation and therefore support the integrative planning of the return-to-work process or engagement in gainful employment. However, further studies are needed to further examine its use in clinical practice and research, when validated in other patient populations and settings.
