Differences Over Time in the Prognostic Effect of Return to Work Self-Efficacy on a Sustained Return to Work

A pilot trial investigating the feasibility of a future randomised controlled trial of Individualised Placement and Support for people unemployed with chronic pain recruiting in primary care

BACKGROUND

We investigated the feasibility of recruiting patients unemployed for more than 3 months with chronic pain using a range of methods in primary care in order to conduct a pilot trial of Individual Placement and Support (IPS) to improve quality of life outcomes for people with chronic pain.

METHODS

This research was informed by people with chronic pain. We assessed the feasibility of identification and recruitment of unemployed patients; the training and support needs of employment support workers to integrate with pain services; acceptability of randomisation, retention through follow-up and appropriate outcome measures for a definitive trial. Participants randomised to IPS received integrated support from an employment support worker and a pain occupational therapist to prepare for, and take up, a work placement. Those randomised to Treatment as Usual (TAU) received a bespoke workbook, delivered at an appointment with a research nurse not trained in vocational rehabilitation.

RESULTS

Using a range of approaches, recruitment through primary care was difficult and resource-intensive (1028 approached to recruit 37 eligible participants). Supplementing recruitment through pain services, another 13 people were recruited (total n = 50). Randomisation to both arms was acceptable: 22 were allocated to IPS and 28 to TAU. Recruited participants were generally not 'work ready', particularly if recruited through pain services.

CONCLUSION

A definitive randomised controlled trial is not currently feasible for recruiting through primary care in the UK. Although a trial recruiting through pain services might be possible, participants could be unrepresentative in levels of disability and associated health complexities. Retention of participants over 12 months proved challenging, and methods for reducing attrition are required. The intervention has been manualised.

Assessing the psychometric properties of the Chinese return-to-work self-efficacy questionnaire using Rasch model analysis

Background

Self-efficacy is a significant predictor of return to work and affects the confidence of survivors to return to work after illness. The Return-to-work self-efficacy (RTW-SE) questionnaire is a self-report questionnaire to assess confidence in returning to work with good reliability and validity. The aim of this study was to translate and cross-culturally adapt the RTW-SE questionnaire into Chinese and examine the psychometric properties among young and middle-aged stroke survivors using Rasch model analysis.

Methods

The cross-cultural adaptation and translation procedures followed a dual-translation approach. The psychometric properties of the RTW-SE questionnaire were examined using Rasch model analysis by Winsteps software. The unidimensionality and local independence were analyzed by principal component analysis of the residuals (PCAR) and standardized residual correlations.Category diagnostics were performed for scale function, and the item fit, reliability, and separation were also validated. Item-person maps were used to examine the distribution and matching of item’s location and person ability. Finally, the differential item functioning (DIF) was used to measure gender-related group equivalence.

Results

A total of 366 participants aged 23–59 years were recruited from three communities in Zhengzhou. The RTW-SE questionnaire demonstrated unidimensionality and a 5-point Likert rating scale was more appropriate to investigate young and middle-aged stroke survivors’self-efficacy. There was a good fit for the items with both person and item reliabilities greater than 0.8 and separation indices of 3.75 and 3.94, respectively. The item location was identified from the item-person map as not covering person ability, but the scale did not have an age-related DIF.

Conclusions

The results confirm evidence of appropriate psychometric properties of the RTW-SE questionnaire and can be used as a reliable and validated instrument for measuring self-efficacy to return to work in young and middle-aged Chinese patients with stroke.

[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.

Individualised placement and support programme for people unemployed because of chronic pain: a feasibility study and the InSTEP pilot RCT

BACKGROUND

Chronic pain is a common cause of health-related incapacity for work among people in the UK. Individualised placement and support is a systematic approach to rehabilitation, with emphasis on early supported work placement. It is effective in helping people with severe mental illness to gain employment, but has not been tested for chronic pain.

OBJECTIVE

To inform the design of a definitive randomised controlled trial to assess the clinical effectiveness of individualised placement and support for people unemployed because of chronic pain.

METHODS

A mixed-methods feasibility study comprising qualitative interviews and focus groups with key stakeholders, alongside a pilot trial.

STUDY PARTICIPANTS

Primary care-based health-care professionals, employment support workers, employers, clients who participated in an individualised placement and support programme, and individuals aged 18-64 years with chronic pain who were unemployed for at least 3 months.

INTERVENTION

An individualised placement and support programme integrated with a personalised, responsive pain management plan, backed up by communication with a general practitioner and rapid access to community-based pain services.

OUTCOMES

Outcomes included stakeholder views about a trial and methods of recruitment; the feasibility and acceptability of the individualised placement and support intervention; study processes (including methods to recruit participants from primary care, training and support needs of the employment support workers to integrate with pain services, acceptability of randomisation and the treatment-as-usual comparator); and scoping of outcome measures for a definitive trial.

RESULTS

All stakeholders viewed a trial as feasible and important, and saw the relevance of employment interventions in this group. Using all suggested methods, recruitment was feasible through primary care, but it was slow and resource intensive. Recruitment through pain services was more efficient. Fifty people with chronic pain were recruited (37 from primary care and 13 from pain services). Randomisation was acceptable, and 22 participants were allocated to individualised placement and support, and 28 participants were allocated to treatment as usual. Treatment as usual was found acceptable. Retention of treatment-as-usual participants was acceptable throughout the 12 months. However, follow-up of individualised placement and support recipients using postal questionnaires proved challenging, especially when the participant started paid work, and new approaches would be needed for a trial. Clients, employment support workers, primary care-based health-care professionals and employers contributed to manualisation of the intervention. No adverse events were reported.

CONCLUSION

Unless accurate and up-to-date employment status information can be collected in primary care health records, or linkage can be established with employment records, research such as this relating to employment will be impracticable in primary care. The trial may be possible through pain services; however, clients may differ. Retention of participants proved challenging and methods for achieving this would need to be developed. The intervention has been manualised.
