Cross-cultural adaptation of the Work Role Functioning Questionnaire 2.0 to Norwegian and Danish.

BACKGROUND: A healthy and productive working life has attracted attention owing to future employment and demographic challenges. OBJECTIVE: The aim was to translate and adapt the Work Role Functioning Questionnaire (WRFQ) 2.0 to Norwegian and Danish. METHODS: The WRFQ is a self-administered tool developed to identify health-related work limitations. Standardised cross-cultural adaptation procedures were followed in both countries' translation processes. Direct translation, synthesis, back translation and consolidation were carried out successfully. RESULTS: A pre-test among 78 employees who had returned to work after sickness absence found idiomatic issues requiring reformulation in the instructions, four items in the Norwegian version, and three items in the Danish version, respectively. In the final versions, seven items were adjusted in each country. Psychometric properties were analysed for the Norwegian sample (n = 40) and preliminary Cronbach's alpha coefficients were satisfactory. A final consensus process was performed to achieve similar titles and introductions. CONCLUSIONS: The WRFQ 2.0 cross-cultural adaptation to Norwegian and Danish was performed and consensus was obtained. Future validation studies will examine validity, reliability, responsiveness and differential item response. The WRFQ can be used to elucidate both individual and work environmental factors leading to a more holistic approach in work rehabilitation.

A prospective study of the association between the readiness for return to work scale and future work participation in Norway.

AIM: The aim of the study was to investigate the associations between the Norwegian version of the Readiness for return to work (RTW) scale and future work participation among persons in inpatient occupational rehabilitation. METHODS: A prospective cohort with one year follow up. The participants (n = 179) were persons with reduced work ability who participated in a one-week inpatient rehabilitation program. Four readiness for RTW factors were identified at baseline using explorative factor analysis: 'RTW inability' and 'RTW uncertainty' among persons not working, and 'uncertain work maintenance' and 'proactive work maintenance' among persons working. Work participation was measured as days without sickness benefits in the year following the rehabilitation program. The associations between work participation and readiness for RTW factors were analyzed in multivariate linear regression models controlling for gender, age, subjective health complaints, employment status and previous sickness benefit. RESULTS: High scores on the RTW inability factor were associated with low future work participation among persons not working before the rehabilitation program. Among persons working before the program, the proactive work maintenance factor was associated with high future work participation. Neither the RTW uncertainty factor nor the uncertain work maintenance factor was associated with future work participation. CONCLUSIONS: The associations between two readiness for RTW factors (RTW inability and proactive work maintenance) and future work participation indicate that these factors can be used as screening tools to tailor occupational rehabilitation programs.

Psychometric properties of the readiness for return to work scale in inpatient occupational rehabilitation in Norway.

AIM: To investigate internal consistency and construct validity of the Readiness for return to work (RTW) scale in a sample participating in a Norwegian inpatient occupational rehabilitation program. METHODS: A cross-sectional study was conducted on baseline measures from a prospective cohort study evaluating a 5 days inpatient occupational rehabilitation program. The participants in the program were 18-67 years, on sickness absence or at risk of sickness absence (N = 193). The Readiness for RTW scale, sociodemographic-, work- and health-related questionnaires were answered by the participants on their first day in the program. Statistical analysis included exploratory factor analyses, reliability analyses and correlations with related instruments. RESULTS: In the scale for those not working (N = 124) two factors were found, representing (1) RTW inability and (2) RTW uncertainty. These factors corresponded to the precontemplation and contemplation stages in a previous Canadian study. The original prepared for action stages were not identified in this sample. In the scale for those working shortly before the program (N = 60) two factors were identified, representing (1) Uncertain work maintenance and (2) Proactive work maintenance, comparable to the stages in the Canadian study. The factors had satisfactory internal consistency (Cronbach's alpha >0.7), except for proactive work maintenance (Cronbach's alpha = 0.59). Expected relationships were found between the readiness for RTW stages and the pain stages of change, fear avoidance beliefs for work, subjective health complaints, decision control and coping at work. CONCLUSION: Internal consistency and construct validity of the readiness for RTW stages found were satisfactory, except for proactive work maintenance. The results indicate that the construct of readiness for RTW may vary by culture and patient setting.
