Validity and test-retest reliability of the Brazilian version of the Return-to-work self-efficacy questionnaire

[French translation and adaptation of the "Return to Work Self-Efficacy' Scale - 11 items" in patients diagnosed with a cancer]

INTRODUCTION

The self-efficacy to return to work is a major psychological factor of the return to work of patients diagnosed with a cancer. However, french investigations in this field do not take this dimension into account due to the lack of a suitable tool for its assessment. The objective of this study was to provide a french translation and adaptation of the "Return to Work Self-Efficacy' scale - 11 items" (RTWSE-11), validated in dutch language in its original version.

METHODS

After translation-back translation steps, completed by experts' consensus meetings, interviews were conducted with thirteen patients diagnosed with cancer in order to evaluate the degree of clarity, simplicity and ambiguity or the various elements of the french version of the RTW-SE-11.

RESULTS

The main modifications inherent to the french adaptation of the questionnaire concerned the modalities of the Likert scale and the inversion of three negative items into positive items.

DISCUSSION

The french translation and adaptation of the RTWSE-11 was particularly faithful to the semantic, idiomatic, functional, experiential, conceptual and operational aspects of the original version. Future work can therefore focus on the psychometrics evaluations of the questionnaire. However, this tool can already be used in clinical practice to establish an initial assessment of the ability of patients diagnosed with cancer to return to work.

Transcultural validation of the return-to-work self-efficacy scale in Korean patients with work-related injuries

Background

This study aimed to develop a Korean version of the Return-to-Work Self-Efficacy (RTWSE)-19 Scale using forward- and backward-translation and investigate the validity of the RTWSE Scale specifically for Korean workers with work-related injuries.

Methods

Participants were 202 injured workers who had filed a claim accepted by the workers’ compensation system and had received medical rehabilitation at workers’ compensation hospitals following a work-related musculoskeletal injury. Among these participants, 88.1% were male, 54.5% were over 45 years, 45.5% were manufacturing employees, and 54.5% were craft or machine operator and assemblers. The 19 item RTWSE-19 scale was developed by Shaw et al. and have three underlying subscales: (i) meeting job demands, (ii) modifying job tasks, and (iii) communicating needs to others. Statistical analysis included exploratory factor analysis (maximum likelihood estimation with oblique quartimin rotation), internal consistency reliability using Cronbach’s alpha, and correlations with related measures: pain intensity; fear-avoidance beliefs; general health; depression; and general self-efficacy.

Results

Using exploratory factor analysis, three factors with 17 items were identified: meeting job demands, modifying job tasks, and communicating needs to others. The removal of two items in the modifying job tasks domain resulted in an increased reliability. The Korean version of the RTWSE-17 showed reasonable model fit (CFI = .963; TLI = .943; RMSEA = .068; SRMR = 0.029), satisfactory reliability (r = 0.925), no floor and ceiling effect, and construct validity.

Conclusions

The Korean RTWSE-17 scale was found to possess good psychometric properties and could address different injury types ranging from fractures to amputations involved in sub-acute and rehabilitation phases in the Korean context. This study’s findings provide insights for practitioners and researchers to return to work after rehabilitation in a Korean clinical and workplace setting.

Development of the empowerment scale for family caregivers of community-dwelling people with dementia in Japan

AIM

This study aimed to develop the empowerment scale for family caregivers of community-dwelling people with dementia (PWD) in Japan (EFCD) and to validate the scale.

METHODS

The questionnaires were mailed to 820 family caregivers of PWD. The first version of the EFCD based on interviews with family caregivers and elderly care specialists and content validity results was tested. Participants also completed the Revised Scale for Caregiving Self-Efficacy and the General Health Questionnaire. For the EFCD development procedure, construct validity was evaluated by item analysis and exploratory factor analysis. Criterion validity was tested using Spearman's correlations between scores of the three scales. Reliability was evaluated using Cronbach's alpha, intraclass correlation coefficients (ICC), and Bland and Altman analysis. The final model was verified by confirmatory factor analysis.

RESULTS

Data from 304 family caregivers were analyzed. Exploratory factor analysis identified a 16-item, four-factor structure for the final version of the EFCD, as follows: (a) Excellent Practice in Dementia Care; (b) Understanding the Essence of Dementia Care; (c) Caring for Oneself as well as for the Person with Dementia; and (d) Having Peers with Shared Support Activities. Reliability and validity of the scale was established using the methods described.

CONCLUSIONS

The developed EFCD is a reliable and valid measure that provides a simple assessment of empowerment among family caregivers of PWD.
