Factor structure and psychometric properties of the European Portuguese version of a questionnaire to assess quality of life in HIV-infected adults: The WHOQOL-HIV-Bref

Patients' and specialists' perspectives on health care quality and on people living with HIV health-related quality of life in Spain: a cross-sectional survey

Spain was close to meeting the 90-90-90-treatment target set by UNAIDS. However, data on health care quality regarding people with HIV and their health-related quality of life (HRQoL) after the COVID-19 pandemic onset is scarce. By considering the perspective of people with HIV and HIV specialists, we aimed to determine some aspects of the quality of care in Spain, such as access to health resources or satisfaction with primary and speciality care, and assess people with HIV health-related quality of life. Ex post facto cross-sectional surveys were administered to 502 people with HIV and 101 HIV clinicians. Unmet needs related to healthcare system and healthcare resources access and to antiretroviral treatment administered by hospital pharmacies were detected. There was also room for improvement in the primary care service delivery and in various aspects concerning people's with HIV HRQoL. About one-fourth of them experienced stigmatisation in the healthcare setting, which was significantly related to HRQoL. Women, heterosexual participants and those with problems accessing the healthcare system scored poorer in the HRQoL scales. Moreover, according to our data, HIV specialists did not seem to be fully aware of patients' with HIV needs and overestimated their HRQoL.

Treatment patterns and preferences of people living with HIV starting or switching antiretroviral therapy: Real-world evidence from Portugal

BACKGROUND

There is a lack of up-to-date real-life evidence on antiretroviral therapy (ART) strategies among people living with HIV (PLWH) in Portugal. This study aimed to describe the treatment strategy used in PLWH either initiating or switching ART.

METHODS

Non-interventional, cross-sectional, multicenter study carried out between December 2019 and October 2021 in Portugal.

RESULTS

A total of 237 PLWH were included in this study, 171 of whom were ART-experienced and 66 were ART-naïve. The study showed that triple regimens were the most common ART strategy and integrase strand transfer inhibitors-based therapy was the most frequently used therapeutic class in both ART-naïve and ART-experienced PLWH. Nevertheless, about a third of PLWH who started a triple regimen transitioned to a dual regimen. Patient-reported outcomes revealed high HIV literacy and similar ART preferences in both groups.

CONCLUSIONS

This real-world study showed that triple regimens were the most widely used ART strategy, even after the European AIDS Clinical Society guidelines introduced the recommendation of a dual regimen for naïve patients. The cohorts of this study presented a high level of HIV literacy at the time of inclusion. Our findings highlighted that taking pills only once a day is considered a very important feature for most patients.

HIV-Specific Reported Outcome Measures: Systematic Review of Psychometric Properties

BACKGROUND

The management of people living with HIV and AIDS is multidimensional and complex. Using patient-reported outcome measures (PROMs) has been increasingly recognized to be the key factor for providing patient-centered health care to meet the lifelong needs of people living with HIV and AIDS from diagnosis to death. However, there is currently no consensus on a PROM recommended for health care providers and researchers to assess health outcomes in people living with HIV and AIDS.

OBJECTIVE

The purpose of this systematic review was to summarize and categorize the available validated HIV-specific PROMs in adults living with HIV and AIDS and to assess these PROMs using the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology.

METHODS

This systematic review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search of 3 recommended databases (PubMed, Embase, and PsychINFO) was conducted on January 15, 2021. Studies were included if they assessed any psychometric property of HIV-specific PROMs in adults living with HIV and AIDS and met the eligibility criteria. The PROMs were assessed for 9 psychometric properties, evaluated in each included study following the COSMIN methodology by assessing the following: the methodological quality assessed using the COSMIN risk of bias checklist; overall rating of results; level of evidence assessed using the modified Grading of Recommendations, Assessment, Development, and Evaluation approach; and level of recommendation.

RESULTS

A total of 88 PROMs classified into 8 categories, assessing the psychometric properties of PROMs for adults living with HIV and AIDS, were identified in 152 studies including 79,213 people living with HIV and AIDS. The psychometric properties of most included PROMs were rated with insufficient evidence. The PROMs that received class A recommendation were the Poz Quality of Life, HIV Symptom Index or Symptoms Distress Module of the Adult AIDS Clinical Trial Group, and People Living with HIV Resilience Scale. In addition, because of a lack of evidence, recommendations regarding use could not be made for most of the remaining assessed PROMs (received class B recommendation).

CONCLUSIONS

This systematic review recommends 3 PROMs to assess health outcomes in adults living with HIV and AIDS. However, all these PROMs have some shortcomings. In addition, most of the included PROMs do not have sufficient evidence for assessing their psychometric properties and require a more comprehensive validation of the psychometric properties in the future to provide more scientific evidence. Thus, our findings may provide a reference for the selection of high-quality HIV-specific PROMs by health care providers and researchers for clinical practice and research.

Use of quality-of-life instruments for people living with HIV: a global systematic review and meta-analysis

Introduction

Due to the effectiveness of combined antiretroviral therapy and its growing availability worldwide, most people living with HIV (PLHIV) have a near‐normal life expectancy. However, PLHIV continue to face various health and social challenges that severely impact their health‐related quality‐of‐life (HRQoL). The UNAIDS Global AIDS Strategy discusses the need to optimize quality‐of‐life, but no guidance was given regarding which instruments were appropriate measures of HRQoL. This study aimed to review and assess the use of HRQoL instruments for PLHIV.

Methods

We conducted a global systematic review and meta‐analysis, searching five databases for studies published between January 2010 and February 2021 that assessed HRQoL among PLHIV aged 16 years and over. Multivariable regression analyses were performed to identify factors associated with the choice of HRQoL instruments. We examined the domains covered by each instrument. Random‐effects meta‐analysis was conducted to explore the average completion rates of HRQoL instruments.

Results and discussion

From 714 publications, we identified 65 different HRQoL instruments. The most commonly used instruments were the World Health Organization Quality‐of‐Life‐ HIV Bref (WHOQOL‐HIV BREF)—19%, Medical Outcome Survey‐HIV (MOS‐HIV)—17%, Short Form‐36 (SF‐36)—12%, European Quality‐of‐Life Instrument‐5 Dimension (EQ‐5D)—10%, World Health Organization Quality‐of‐Life Bref (WHOQOL BREF)—8%, Short Form‐12 (SF‐12)—7% and HIV/AIDS Targeted Quality‐of‐Life (HAT‐QOL)—6%. There were greater odds of using HIV‐specific instruments for middle‐ and low‐income countries (than high‐income countries), studies in the Americas and Europe (than Africa) and target population of PLHIV only (than both PLHIV and people without HIV). Domains unique to the HIV‐specific instruments were worries about death, stigma and HIV disclosure. There were no significant differences in completion rates between different HRQoL instruments. The overall pooled completion rate was 95.9% (95% CI: 94.7−97.0, I² = 99.2%, p < 0.01); some heterogeneity was explained by country‐income level and study type.

Conclusions

A wide range of instruments have been used to assess HRQoL in PLHIV, and the choice of instrument might be based on their different characteristics and reason for application. Although completion rates were high, future studies should explore the feasibility of implementing these instruments and the appropriateness of domains covered by each instrument.

Determinants of the quality of life amongst HIV clinic attendees in Malang, Indonesia

BACKGROUND

As the number of people living with human immunodeficiency virus (HIV; PLHIV) in Indonesia has increased in recent years, more efforts have been expended to improve their health status. However, in a country where PLHIV are very much stigmatized, there has been little research concerning their quality of life (QoL). Hence, this study aimed to assess the QoL among PLHIV and its associated factors. Findings of this research can contribute to improving the health and wellbeing of PLHIV in Indonesia.

METHODS

A cross-sectional survey with convenience sampling was conducted from June to September 2018, at four healthcare centers in Malang, Indonesia. PLHIV, aged 18 years or over, were asked if they would like to participate in this study when they came to a health center to receive services. To protect confidentiality, the healthcare staff at the clinics assisted with recruitment and face-to-face interviews with structured questionnaires. Measurements included sociodemographic, medication-related, social support, HIV-stigma, and QoL variables.

RESULTS

In total, 634 PLHIV agreed to participate in this study. A multivariate linear regression analysis showed that being older, having a job, living in an urban area, having better access to healthcare services, adhering to medication, being in an antiretroviral therapy (ART) program for more than 1 year, experiencing a lower level of stigma, and receiving more social support were associated with a better QoL. The regression model had an adjusted R2 of 0.21.

CONCLUSIONS

Findings from this research have significant policy implications. Policies focused on reducing social stigma and promoting medication adherence will likely have a positive impact on the QoL of PLHIV. Increasing public awareness and acceptance of PLHIV in Indonesia remains challenging, but would likely have significant impacts. Furthermore, interventions should also focus on reducing disparities in QoL between PLHIV living in rural areas and those in urban areas.

Psychometric properties of the Chinese version of the TeamSTEPPS teamwork perceptions questionnaire to measure teamwork perceptions of Chinese residents: a cross-sectional study

OBJECTIVES

The purpose of this research was to evaluate the psychometric properties of the TeamSTEPPS Teamwork Perception Questionnaire (T-TPQ) among the Chinese residents.

DESIGN

Cross-sectional study.

SETTING

A clinical hospital of the China Medical University in Liaoning Province, China.

PARTICIPANTS

A total of 664 residents were enrolled in this research. The valid response rate was 83.0% (664 of 800 residents).

MAIN OUTCOME MEASURES

Internal consistency and test-retest reliability were used to assess the reliability of the questionnaire. The construct validity of the Chinese T-TPQ was evaluated by confirmatory factor analysis. Furthermore, the concurrent, convergent and discriminant validity were analysed.

RESULTS

Cronbach's α coefficient of the T-TPQ in Chinese language was 0.923. Except for the communication dimension (0.649), the Cronbach's α coefficient of all dimensions were satisfactory. The T-TPQ and its five dimensions reported a good test-retest reliability (0.740-0.881, p<0.01). Moreover, the results of the confirmatory factor analysis demonstrated that the construct validity of the Chinese T-TPQ was satisfactory. All dimensions significantly correlated with the Hospital Survey on Patient Safety Culture (HSOPSC) teamwork within units dimension and the Safety Attitudes Questionnaire (SAQ) teamwork climate dimension (p<0.01), and the questionnaire showed satisfactory convergent and discriminant validity.

CONCLUSIONS

The T-TPQ in Chinese language demonstrated good psychometric characteristics and was a reliable and valid questionnaire to measure the Chinese health professionals' perception of teamwork. Thus, the Chinese version of the T-TPQ could be applied in teamwork training programmes and medical education research.

Global Research on Quality of Life of Patients with HIV/AIDS: Is It Socio-Culturally Addressed? (GAPRESEARCH)

Quality of life (QOL) has been considered as an important outcome indicator in holistic care for HIV-infected people, especially as HIV/AIDS transforms from a fatal illness to a chronic condition. This study aimed to identify trends and emerging topics among research concerning the QOL of people living with HIV/AIDS (PLWHA). The analyzed data were English papers published from 1996 to 2017, searched and extracted from the Web of Science Core Collection. Collaborations between countries and the correlation between the keywords were visualized by VOSviewer while the abstracts’ content was analyzed using exploratory factor analysis and Jaccard’s’ similarity index. There has been an increase in both the number of publications and citations. The United Nations of America leads in terms of paper volume. The cross-nation collaborations are mainly regional. Despite a rather comprehensive coverage of topics relating to QOL in PLWHA, there has evidently been a lack of studies focusing on socio-cultural factors and their impacts on the QOL of those who are HIV-infected. Further studies should consider investigating the role of socio-cultural factors, especially where long-term treatment is involved. Policy-level decisions are recommended to be made based on the consideration of cultural factors, while collaborations between developed and developing nations, in particular in HIV/AIDS-ridden countries, are strongly recommended.

Assessing quality of life in people with HIV in Spain: psychometric testing of the Spanish version of WHOQOL-HIV-BREF

Background

The assessment of health-related quality of life (HRQoL) in people living with HIV (PLHIV) has become crucial to evidence-based practice. The goals of this study are to analyze the psychometric properties and evidence of the validity of the Spanish version of WHOQOL-HIV-BREF in a sample of PLHIV in Spain and to examine the more impaired HRQoL facets and dimensions and identify the PLHIV who show the most vulnerable profile.

Methods

A total of 1462 PLHIV participated in an observational cross-sectional ex-post-facto study. Data were collected at 33 Spanish sites through an online survey. In addition to measuring HRQoL, the study used other tools to measure treatment adherence (CEAT-VIH 2.0 version), psychological well-being (GHQ-12) and HIV-related stigma (HSSS). Cronbach’s alpha, first- and second-order confirmatory factor analysis (CFA), the Pearson coefficient and one-way ANOVA were used to evaluate reliability, construct validity and concurrent and known-group validity, respectively. Differences according to the socio-demographic and epidemiological profiles of participants were analyzed.

Results

First- and second-order CFAs confirmed a six-domain first-order structure of the Spanish version of WHOQOL-HIV-BREF and one second-order factor related to overall HRQoL with an acceptable fit to the data, although some minor changes would improve it. The six-domain structure showed an acceptable internal consistency (Cronbach’s alpha ranged from .61 to .81). Significant moderate to large correlations between domains and overall HRQoL, adherence, psychological well-being and negative self-image were found. Significant differences were found according to participants’ self-reported CD4+ cell count in several HRQoL facets and domains. Being female, heterosexual, having low socio-economic and educational statuses, having acquired HIV through an unsafe injection and living more years with HIV were related to poorer HRQoL. PLHIV older than 50 presented lower scores in 19 HRQoL facets.

Conclusions

This study demonstrates that the Spanish version of the WHOQOL-HIV-BREF is a valid instrument. It also presents the most recent data about HRQoL in PLHIV in Spain with the largest sample to date.

Psychosocial factors associated with poor outcomes after amputation for complex regional pain syndrome type-I

Background

Amputation for longstanding therapy resistant complex regional pain syndrome type-I (CRPS-I) is controversial. Reported results are inconsistent. It is assumed that psychological factors play a role in CRPS-I.

Objective

To explore which psychological factors prior to amputation are associated with poor outcomes after amputation in the case of longstanding therapy resistant CRPS-I.

Methods

Between May 2008 and August 2015, 31 patients with longstanding therapy resistant CRPS-I were amputated. Before the amputation 11 psychological factors were assessed. In 2016, participants had a structured interview by telephone and filled out questionnaires to assess their outcome. In case of a perceived recurrence of CRPS-I a physician visited the patient to examine the symptoms. Associations between psychological factors and poor outcomes were analysed.

Results

Four of the 11 psychological factors were associated with poor outcomes. Regression analyses showed that change in the worst pain in the past week was associated with poor social support (B = 0.3, 95% confidence interval: 0.1;0.6) and intensity of pain before amputation (B = 2.0, 95% confidence interval 0.9;3.0). Patients who reported important improvements in mobility (n = 23) had significantly higher baseline resilience (median 79) compared to those (n = 8) who did not report it (median 69)(Mann-Whitney U, Z = -2.398, p = 0.015). Being involved in a lawsuit prior to amputation was associated with a recurrence in the residual limb (Bruehl criteria). A psychiatric history was associated with recurrence somewhere else (Bruehl criteria).

Conclusion

Poor outcomes of amputation in longstanding therapy resistant CPRS-1 are associated with psychological factors. Outstanding life events are not associated with poor outcome although half of the participants had experienced outstanding life events.

Measuring quality of life among people living with HIV: a systematic review of reviews

AIM

A systematic review of reviews was conducted to identify and appraise brief measures of health-related quality of life (HRQoL) that have been used in peer-reviewed research with people living with HIV.

METHODS

The review was conducted in two stages: 1) search of electronic databases to identify systematic reviews of tools used to measure HRQoL in adults living with HIV, published since the year 2000; 2) selection of HRQol scales from those identified in the reviews. Inclusion criteria included scales that could be self-administered in 10 min or less, covering at least 3 domains of quality of life (physical function, social/role function and mental/emotional function). For generic scales, inclusion criteria included the availability of normative data while for HIV-specific scales, patient input into the development of the scale was required.

RESULTS

Ten reviews met the inclusion criteria. Nine generic scales met the inclusion criteria: the EuroQol five dimensions questionnaire (EQ-5D); Health Utilities Index; McGill Quality of Life questionnaire; Medical Outcomes Study (MOS) Short Form (SF)-12; SF-36; World Health Organisation Quality of Life (WHOQOL- BREF), Questions of Life Satisfaction (FLZM) and SF-20. Available psychometric data supported the EQ-5D and SF-36. Seven HIV-specific scales met the inclusion criteria: the AIDS Clinical Trials Group (ACTG)-21; HIV-QL-31; MOS-HIV; Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV), PROQOL-HIV, Symptom Quality of Life Adherence (HIV-SQUAD) and the WHOQOL-HIV BREF. Of the HIV -specific measures, the MOS-HIV was considered to have the most well-established psychometric properties, however limitations identified in the reviews included insufficient input from people living with HIV in the development of the scale, cross-cultural relevance and continued applicability. Two relatively new measures, the WHOQOL-HIV BREF and PROQOL-HIV, were considered to have promising psychometric properties and may have more relevance to people living with HIV.

CONCLUSION

The findings highlight the need for further validation of HRQoL measures in people living with HIV. The choice of one measure over another is likely to be influenced by the purpose of the quality of life assessment and the domains of HRQoL that are most relevant to the specific research or clinical question.

Psychometric properties of the Chinese version of the WHOQOL-HIV BREF to assess quality of life among people living with HIV/AIDS: a cross-sectional study

OBJECTIVES

This study aims to assess the psychometric properties of the Chinese version of the WHOQOL-HIV BREF.

DESIGN

Cross-sectional study.

SETTING

Centers for Disease Control and Prevention and infectious disease hospitals in three Chinese provinces.

PARTICIPANTS

Sample of 1100 people living with HIV/AIDS (PLWHA).

INTERVENTIONS

We recruited 1100 PLWHA to evaluate their quality of life (QOL) using the WHOQOL-HIV BREF. Of these participants, 57 were randomly selected to repeat the QOL evaluation 2 weeks later.

MAIN OUTCOME MEASURES

The reliability of the WHOQOL-HIV BREF was assessed in terms of its internal consistency and test-retest reliability. The construct, concurrent, convergent, discriminant and known-group validity were also analysed. In addition, the factorial invariance across genders was assessed.

RESULTS

Cronbach's α coefficient for the overall scale was 0.93. Except for the spirituality domain, which had an α below 0.70 (0.66), the other five domains showed adequate internal consistency. The test-retest reliability revealed a statistically significant intraclass correlation coefficient of 0.72-0.82 (p<0.001). Confirmatory factor analysis found that the six-domain structure produced an acceptable fit to the data. The instrument showed factorial invariance across gender groups. All domains were significantly correlated with the general items and the SF-36 (p<0.01). The correlation coefficients were >0.40 (r=0.40-0.67), except for the association between the spirituality domain and two general items (QOL: r=0.33; health status: r=0.36). Subjects with lower CD4 counts had lower scores for all domains (p<0.05). Symptomatic participants had significantly lower scores than asymptomatic participants on the physical, psychological and independence domains (p<0.05).

CONCLUSIONS

The WHOQOL-HIV BREF revealed good psychometric characteristics among Chinese PLWHA. These findings offer promising support for the use of the WHOQOL-HIV BREF as a measure of QOL among Chinese PLWHA and in cross-cultural comparative studies on QOL.

Adaptation and validation of the short version WHOQOL-HIV in Ethiopia

BACKGROUND

Quality of life of patients is an important element in the evaluation of outcome of health care, social services and clinical trials. The WHOQOL instruments were originally developed for measurement of quality of life across cultures. However, there were concerns raised about the cross-cultural equivalence of the WHOQOL-HIV when used among people with HIV in Ethiopia. Therefore, this study aimed at adapting the WHOQOL-HIV bref for the Ethiopian setting.

METHODS

A step-wise adaptation of the WHOQOL-HIV bref for use in Ethiopia was conducted to produce an Ethiopian version-WHOQOL-HIV-BREF-Eth. Semantic and item equivalence was tested on 20 people with HIV. One hundred people with HIV were interviewed to test for measurement equivalence (known group validity and internal consistency) of the WHOQOL-HIV-BREF-Eth. Confirmatory factor analysis was conducted using data from 348 people with HIV who were recruited from HIV clinics.

RESULTS

In the process of adaptation, new items of relevance to the context were added while seven items were deleted because of problems with acceptability and poor psychometric properties. The Cronbach's α for the final tool with twenty-seven items WHOQOL-HIV-BREF-Eth was 0.93. All six domains discriminated well between symptomatic and asymptomatic people with HIV (p < 0.001). Using confirmatory factor analysis, a second order factor structure with six first order indicator factors demonstrated moderate fit to the data ((χ(2) = 627.75; DF = 259; p < 0.001), CFI = 0.82, TLI = 0.77 and RMSEA = 0.064).

CONCLUSION

The WHOQOL-HIV-BREF-Eth has been shown to be a valid measure of quality of life for use in clinical settings among people with HIV in Ethiopia.

Quality of life of people living with HIV/AIDS: a cross-country comparison study of Finland and Portugal

The premises underlying the development of the World Health Organization Quality of Life (WHOQOL) instruments provide a convincing rationale for comparing quality of life (QoL) across countries. The aim of the present study was to compare the QoL of patients living with HIV infection in Finland and in Portugal, and to examine the contribution of the QoL domains to the overall QoL in these two countries. The sample comprised 453 patients from Finland (76.3% male; mean age = 46.50) and 975 from Portugal (69.2% male; mean age = 40.98), all living with HIV. QoL data were collected by use of the WHOQOL-HIV-Bref questionnaire. Significant country differences were found in QoL domains and specific facets. Patients from Finland reported markedly higher scores on all six QoL domains and general facet, than did their Portuguese counterparts. Regarding the specific facets of the WHOQOL-HIV-Bref, patients from Finland also reported significantly higher scores on 24 out of 29. The exceptions were dependence on medications and treatment, positive feelings, personal relationships, sexual activity, and on spirituality, religion and personal beliefs. Regression analyses showed that physical, psychological, and independence domains contributed to overall QoL among the Finnish patients (R(2) = 0.63), whereas among the Portuguese, the domains significantly associated with overall QoL were physical, psychological, independence, and environment (R(2) = 0.48). Country differences in QoL domains and specific facets may reflect sociocultural differences between southern and northern Europe.

Factors associated with quality of life in middle-aged and older patients living with HIV

HIV infection has been historically considered a disease of young adults; however, adults aged 50 years and older represent now an increasing proportion of HIV cases worldwide, including in Portugal. In this context, given the considerable burden associated with living with HIV, the topic of quality-of-life (QoL) assessment has become increasingly relevant. The aims of this study were to examine the age-related differences in QoL and depressive symptoms of younger and middle-aged and older adults with HIV as well as the sociodemographic, HIV-related and depressive symptoms (cognitive-affective and somatic) associated with QoL domains. The sample consisted of 1194 HIV-infected patients, recruited from 10 Portuguese hospitals. QoL data were collected using the WHOQOL-HIV-Bref questionnaire. Patients also completed the Beck Depression Inventory. Of the 1194 patients, 185 (15.5%) were over 50 years old. Middle-aged and older patients reported significantly lower QoL in the physical, independence and social relationships domains. Regarding the specific facets of QoL, middle-aged and older patients reported significantly lower scores in seven of the 29 specific facets of the WHOQOL-HIV-Bref and higher scores in one facet (financial resources). Overall, among middle-aged and older patients, higher education, being employed, a shorter time since HIV diagnosis, use of combination anti-retroviral therapy and fewer depressive symptoms were significantly associated with higher QoL ratings. Our findings suggest that both cognitive-affective and somatic depressive symptoms account for significant variability in QoL scores in middle-aged and older patients. Because an important feature of healthy ageing is maintaining QoL, these data may provide useful information for tailoring age-appropriate and effective interventions to improve the mental health and QoL of middle-aged and older patients living with HIV.

Quality of life in rehabilitation outpatients: normal values and a comparison with the general Dutch population and psychiatric patients

Purpose

To provide Dutch normal values for rehabilitation outpatients with chronic pain or musculoskeletal diseases utilizing the World Health Organization Quality of Life questionnaire abbreviated version (WHOQOL-BREF) and analyse influence of diagnosis and patient characteristics on normal values and increase understanding in those values.

Methods

Five hundred and forty-two outpatients were referred to a rehabilitation psychologist. Referral diagnoses were “musculoskeletal”, “chronic pain”, “neurological” and “miscellaneous”. Comparisons between groups were made for each of the four domains of the WHOQOL-BREF (scoring range 4–20).

Results

Domain scores of rehabilitation outpatients were physical domain 11.0 (±2.7), psychological domain 13.6 (±2.4), social domain 14.8 (±3.4) and environmental domain 14.2 (±2.2). Outpatients with chronic pain reported the lowest scores on the WHOQOL-BREF when compared to the “musculoskeletal”, “neurological” and “miscellaneous” groups. Increased age, lower education, living alone and unemployment had a negative impact on WHOQOL-BREF scores. Compared to the general Dutch population, rehabilitation outpatients scored, unadjusted for age, significantly lower difference for the physical domain 4.5 [95 % confidence interval (CI) 4.2; 4.8], the environment domain 1.7 (95 % CI 1.5; 2.0), the psychological domain 1.1 (95 % CI 0.4; 1.2) and the social domain 0.4 (95 % CI 0.0; 0.8).

Conclusions

WHOQOL-BREF scores of rehabilitation outpatients are lower and differed significantly from normal values of a Dutch population in all four domains. Therefore, the WHOQOL-BREF can be used to measure the subjective impact of their disease or injury. The subjective impact of chronic pain was found to be particularly high.
