The Dutch Recovering Quality of Life questionnaire (ReQoL) and its psychometric qualities

Mapping Short Warwick and Edinburgh Mental Wellbeing Scale (SWEMWBS) to Recovering Quality of Life (ReQoL) to estimate health utilities

BACKGROUND

The Short Warwick and Edinburgh Mental Wellbeing Scale (SWEMWBS) is a widely used non-preference-based measure of mental health in the UK. The primary aim of this paper is to construct an algorithm to translate the SWEMWBS scores to utilities using the Recovering Quality of Life Utility Index (ReQoL-UI) measure.

METHODS

Service users experiencing mental health difficulties were recruited in two separate cross-sectional studies in the UK. The following direct mapping functions were used: Ordinary Least Square, Tobit, Generalised Linear Models. Indirect (response) mapping was performed using seemingly unrelated ordered probit to predict responses to each of the ReQoL-UI items and subsequently to predict using UK tariffs of the ReQoL-UI from SWEMWBS. The performance of all models was assessed by the mean absolute errors, root mean square errors between the predicted and observed utilities and graphical representations across the SWEMWBS score range.

RESULTS

Analyses were based on 2573 respondents who had complete data on the ReQoL-UI items, SWEMWBS items, age and sex. The direct mapping methods predicted ReQoL-UI scores across the range of SWEMWBS scores reasonably well. Very little differences were found among the three regression specifications in terms of model fit and visual inspection when comparing modelled and actual utility values across the score range of the SWEMWBS. However, when running simulations to consider uncertainty, it is clear that response mapping is superior.

CONCLUSIONS

This study presents mapping algorithms from SWEMWBS to ReQoL as an alternative way to generate utilities from SWEMWBS. The algorithm from the indirect mapping is recommended to predict utilities from the SWEMWBS.

A smartphone-based intervention for young people who self-harm ('PRIMARY'): study protocol for a multicenter randomized controlled trial

BACKGROUND

Self-harm in young people is a public health concern connected with severe mental health problems, such as personality pathology. Currently, there are no specific evidence-based interventions available for young people who self-harm. Therefore, we developed PRe-Intervention Monitoring of Affect and Relationships in Youth (PRIMARY), a smartphone-based intervention, co-designed by clinicians and young people with lived experience of mental ill-health. PRIMARY combines the Experience Sampling Method (ESM) with weekly report sessions. The study aims to examine the effectiveness of PRIMARY with regard to reducing self-harm, and improving emotion regulation and quality of relationships.

METHODS

This study is a multicenter, parallel groups, randomized controlled trial (RCT) comparing the PRIMARY intervention to a waiting list control group. PRIMARY comprises 28 consecutive days of questionnaires five times each day (i.e., ESM) and four weekly report sessions. Participants will comprise 180 young people referred for treatment to the participating Dutch mental healthcare institutions and (1) are aged 12 to 25 years, and (2) engaged in ≥ 1 act of self-harm in the past year. Participants are randomly allocated to a study group after screening in a 1:1 ratio by an independent researcher using computer-generated randomization sequences with stratified block randomization by age (12 to 15 years / 16 to 25 years). Staff will conduct assessments with all participants at baseline (Wave 1), after 28 days (Wave 2), and in a subsample after 10 weeks of subsequent specialized treatment (Wave 3). The primary outcomes are self-harm, emotion regulation, and quality of relationships. Secondary outcomes include patient and clinician satisfaction. Exploratory analyses of ESM data will examine the relationship between emotions, social relationships, and self-harm.

DISCUSSION

The results of this trial will clarify whether an innovative smartphone-based intervention is effective for reducing self harm and improving emotion regulation and the quality of social relationships. It has the potential to fill a treatment gap of interventions specifically targeting self-harm. If proven effective, it would provide an accessible, easy-to-implement, low-cost intervention for young people. Furthermore, the ESM-data will allow detailed analyses into the processes underlying self-harm, which will contribute to theoretical knowledge regarding the behavior.

A blended module (STAIRS) to promote functional and personal recovery in patients with a major depressive disorder in remission: study protocol of a concurrent mixed methods randomized controlled trial

BACKGROUND

Despite the availability of a wide variety of evidence-based treatments for major depressive disorder (MDD), many patients still experience impairments in their lives after remission. Programs are needed that effectively support patients in coping with these impairments. The program Storytelling and Training to Advance Individual Recovery Skills (STAIRS) was developed to address this need and combines the use of peer contact, expert-by-experience guidance, family support and professional blended care. The aim of the planned study is (1) to assess the efficacy of the STAIRS program in patients with remitted MDD, (2) to investigate patients' subjective experiences with STAIRS, and (3) to evaluate the program's cost-effectiveness.

METHODS

A concurrent mixed-methods randomized controlled trial design will be used. Patients aged between 18 and 65 years with remitted MDD (N = 140) will be randomized to either a group receiving care as usual (CAU) + the STAIRS-program or a control group receiving CAU + some basic psychoeducation. Quantitative efficacy data on functional and personal recovery and associated aspects will be collected using self-report questionnaires at the start of the intervention, immediately following the intervention, and at the six-month follow-up. Insights into patients' experiences on perceived effects and the way in which different program elements contribute to this effect, as well as the usability and acceptability of the program, will be gained by conducting qualitative interviews with patients from the experimental group, who are selected using maximum variation sampling. Finally, data on healthcare resource use, productivity loss and quality of life will be collected and analysed to assess the cost-effectiveness and cost-utility of the STAIRS-program.

DISCUSSION

Well-designed recovery-oriented programs for patients suffering from MDD are scarce. If efficacy and cost-effectiveness are demonstrated with this study and patients experience the STAIRS program as usable and acceptable, this program can be a valuable addition to CAU. The qualitative interviews may give insights into what works for whom, which can be used to promote implementation.

Psychometric evaluation of the German version of the Recovering Quality of Life (ReQoL) measures in patients with affective disorders

BACKGROUND

The generic self-reported Recovering Quality of Life (ReQoL) measures were developed for measuring recovery-focused health-related quality of life (HrQoL) in persons with mental health conditions. The aim of this study was to assess the psychometric properties of the German version of the ReQoL measures in patients with affective disorders in Germany.

METHODS

Data from a patient sub-sample in a randomized controlled trial have been used (N = 393). The internal consistency and the test-retest reliability of the ReQoL measures were assessed using Cronbach's Alpha and the intra-class correlation coefficient (ICC). The concurrent validity and the known-group validity of the ReQoL measures were assessed using Pearson's Correlation coefficient and Cohen's d. The responsiveness was assessed using Glass' Δ and the standardized response mean (SRM).

RESULTS

The reliability among the items of the ReQoL-20 was overall excellent. The ICC of the ReQoL-20 was r = 0.70, indicating moderate test-retest reliability. The concurrent validity of the ReQoL-20 with the clinical measure PHQ-9 was strong with a correlation coefficient of r = - 0.76. The known-group validity of the ReQoL-20 using PHQ-9 cut-off points was large with an effect size of d = 1.63. The ReQoL measures were sensitive to treatment response and remission of symptoms measured by the PHQ-9 with large effect sizes/SRM.

DISCUSSION

The psychometric properties of the ReQoL measures for the assessment of patients with affective disorders were overall good. With the ReQoL, valid and reliable measures for the assessment of recovery-focused HrQoL for persons with affective disorders are available in German language.

Translation and linguistic validation of the Swedish recovering quality of life (ReQoL) - A brief research report

In research and among clinicians, the focus has shifted from mainly symptom reduction and increasing functionality to a more recovery-oriented focus. Although there are instruments measuring recovery, there has been a lack of instruments sensitive enough to measure the quality of life for people with severe mental health disorders. Therefore, this study aimed to obtain a Swedish version of the Recovering Quality of Life (ReQoL) questionnaire adhering to best practice guidelines using various steps of translation, linguistic validation, and cognitive debriefing. The cognitive debriefing was conducted with seven participants, and all felt the items in the questionnaire were relevant to their health, apprehensible, and easy to complete. However, some issues were raised regarding wording and the concepts behind certain items. All feedback was considered, and some items were revised in response to criticism after continuous discussions. A Swedish version of ReQoL now exists, and although there is a need for ReQoL in different clinical research settings in Sweden, further research is required to psychometrically test the construct validity as well as reliability of the Swedish version in Sweden.

Validation of the Recovering Quality of Life (ReQoL) questionnaires for patients with anxiety, obsessive-compulsive, stress-related, somatoform and personality disorders in Germany

The health-related quality of life (HrQoL) and the recovery process of persons with mental health conditions can be assessed with the Recovering Quality of Life questionnaires (ReQoL-20 and ReQoL-10). The aim of this study was to assess the psychometric properties of the German version of the ReQoL measures in patients with anxiety, obsessive-compulsive, stress-related, and somatoform disorders and in patients with disorders of adult personality and behavior. This study was based on a sub-sample of patients that were included in a randomized controlled trial evaluating an evidence-based, stepped and coordinated care service model for mental disorders (RECOVER). The internal consistency was assessed using Cronbach's Alpha and the test-retest reliability was assessed by the intra-class correlation coefficient (ICC). Concurrent validity was assessed by Pearson's Correlation Coefficient and the known-group validity was assessed using the Cohen's d. The internal consistency of the ReQoL-20 and ReQoL-10 was excellent and good with Cronbach's alpha of α = 0.91 and α = 0.83 for all items. The test-retest reliability of the ReQoL measures was moderate with ICC of r = 0.72 to 0.74. The concurrent validity of the ReQoL measures with the Global Severity Index was overall high with a correlation coefficient of r = -0.70. In conclusion, for patients with anxiety, obsessive-compulsive, stress-related, somatoform and personality disorders, the German version of the ReQoL measures is valid and reliable for the assessment of HrQoL and the recovery process.

Adult Attachment and Personal Recovery in Clients With a Psychotic Disorder

Background

Personal recovery has become a key objective in the treatment of clients with a psychotic disorder. So far it has been established that the two attachment dimensions, ie, anxious and avoidant, are negatively associated with subjective well-being, self-esteem and hope. This study is the first to explore whether attachment styles are related to personal recovery in this population.

Aims

To study the effects of anxious and avoidant attachment on personal recovery in a population with a psychotic disorder.

Method

This cross-sectional study is part of the UP's multicenter cohort study on recovery from psychotic disorders, in which 265 participants are currently included. Attachment was assessed using the Psychosis Attachment Measure, including the anxious and avoidant attachment dimensions. Personal recovery was measured using the Recovering Quality of Life-10 (ReQOL-10) and the Individual Recovery Outcomes Counter (I.ROC). Regression analysis was used to investigate the effect of attachment on personal recovery.

Results

We found negative effects of the anxious attachment style on the total scores of the ReQoL-10 (b = -4.54, SE = 0.69, β = β0.37) and the I.ROC (b = -5.21, SE = 0.89, β = -0.32). Although there were also negative effects of the avoidant attachment style on the total scores of the ReQoL-10 (b = -3.08, SE = 0.93, β = -0.18) and the I.ROC (b = -4.24, SE = 1.24, β = -0.19), these were less pronounced.

Conclusion

Results show that both forms of insecure attachment (anxious and avoidant) are related to poorer personal recovery in clients with a psychotic disorder.

The Association Between Executive Functioning and Personal Recovery in People With Psychotic Disorders

Background

Recovery in psychotic disorder patients is a multidimensional concept that can include personal, symptomatic, societal, and functional recovery. Little is known about the associations between personal recovery (PR) and functional recovery (FR). FR involves a person's ability to recover or compensate for impaired cognition, such as executive functions, and the loss of skills.

Method

In this cross-sectional study (the UP'S study), we used measures of executive functioning and personal recovery to assess a cohort of people with a psychotic disorder. PR was measured using the Recovering Quality of Life (ReQOL) and Individual Recovery Outcomes (I.ROC). FR was assessed using two forms of assessment. The Behavioral Rating Inventory of Executive Functioning Adult version (BRIEF-A) was used for self-rated executive functioning, and the Tower of London (TOL) for performance-based executive functioning. Regression models were calculated between executive functioning (BRIEF-A and TOL) and PR (ReQOL and I.ROC). Model selection was based on the Wald test.

Results

The study included data on 260 participants. While total scores of BRIEF-A had a small negative association with those of the ReQOL (β = -0.28, P > .001) and the I.ROC (β = -0.41, P > .001), TOL scores were not significantly associated with the ReQOL scores (β = 0.03, P = .76) and the I.ROC scores (β = 0.17, P = 0.17).

Conclusion

Self-reported EF, which measures the accomplishment of goal pursuit in real life was associated with PR. However, processing efficiency and cognitive control as measured by performance-based EF were not.

The Recovering Quality of Life 10-item (ReQoL-10) scale in a first-episode psychosis population: Validation and implications for patient-reported outcome measures (PROMs)

AIM

This study aimed to examine the psychometric performance of the Recovering Quality of Life scale 10-item version (ReQoL-10) using a sample from a Singapore first-episode psychosis intervention program, to explore its clinical and sociodemographic correlates, and to discuss its utility as a patient-reported outcome measure (PROM).

METHODS

Sociodemographic data, duration of untreated psychosis (DUP), and diagnosis were collected from 300 participants. Clinical data, which included baseline and current scores on the Patient Health Questionnaire 9-item version, EuroQoL-5 Dimension 3-level version, Positive and Negative Syndrome Scale, and Global Assessment of Functioning scale, were extracted. The ReQoL-10 was tested for structural validity, internal consistency, and construct validity, and a multiple linear regression determined if any of the baseline factors were statistically significant predictors of the total ReQoL-10 scores.

RESULTS

The mean (SD) total ReQoL-10 score of the sample was 27.8 (7.8). Confirmatory factor analysis confirmed the bifactor model structure of the ReQoL-10. The instrument demonstrated good internal consistency and adequate construct validity. Being older was associated with higher total ReQoL-10 scores, while being married, having a highest educational level of vocational/diploma, longer DUP, and a diagnosis of affective psychosis were associated with lower total ReQoL-10 scores.

CONCLUSIONS

This study has validated the ReQoL-10 as suitable for routine use to measure recovery-specific quality of life in a psychiatric setting among patients with first-episode psychosis, and is a potential tool to initiate recovery conversations. As a PROM, it can facilitate shared decision making, in line with efforts to evaluate and improve quality of care.

Psychometric Evaluation of the Chinese Recovering Quality of Life (ReQoL) Outcome Measure and Assessment of Health-Related Quality of Life During the COVID-19 Pandemic

Objective

The primary objective was to translate the Recovering Quality of Life (ReQoL) measures from English to traditional Chinese and assess their psychometric properties in Hong Kong (HK) Chinese population. The secondary objective was to investigate the mental health-related quality of life (HRQoL) of this sample during the coronavirus disease 2019 (COVID-19) pandemic.

Method

Recovering Quality of Life was translated to Traditional Chinese adhering to standard guideline recommended by the official distributors. Five hundred members of the general population were successfully recruited to participate in a telephone-based survey. The following psychometric properties of the ReQoL were evaluated: construct, convergent, and known-group validity and internal consistency and test-retest reliability. The item measurement invariance was assessed on the basis of differential item functioning (DIF). Multiple regression analysis was used to assess the relationship between respondents' characteristics and mental HRQoL.

Results

Results of confirmatory factor analysis (CFA) supported a two-factor structure of the ReQoL. The ReQoL showed significant correlations with the other mental health, quality of life, and well-being measures, which indicated a satisfactory convergent validity. Known-group validity confirmed that ReQoL is able to differentiate between people with different mental health status. The (Cronbach's alpha = 0.91 and 0.76 for positive [PF] and negative [NF] factor), and McDonald's omega of 0.89 (PF = 0.94, NF = 0.82) indicated the ReQoL has good reliability as well as test-retest reliability with an intraclass correlation coefficient of 0.75. Four items showed negligible DIF with respect to age. Respondents who were highly educated and without psychological problems reported a high ReQoL score.

Conclusion

Traditional Chinese ReQoL was shown to be a valid and reliable instrument to assess the recovery-focused quality of life in HK general population. Future studies are needed to appraise its psychometric properties in local people experiencing mental disorders.
