Prospective Evaluation of Positivity Rates of Aspergillus-Specific IgG and Quality of Life in HIV-Negative Tuberculosis Patients in Lagos, Nigeria.

BACKGROUND: Pulmonary tuberculosis (PTB) often results in residual anatomical and functional changes despite microbiological cure and may be complicated by chronic pulmonary aspergillosis (CPA). In this study, we determined the perceived health-related quality of life (HRQoL) of patients during and after PTB therapy and compared it with their quantitative Aspergillus-specific IgG positivity rates. METHODOLOGY: We conducted a longitudinal study among TB patients attending two directly observed therapy short-course (DOTS) clinics in Lagos, Nigeria. Two hundred and four confirmed TB patients were recruited over 9 months, with five visits at baseline and 3, 6, 9, and 12 months. They were all acid-fast bacilli smear, GeneXpert, or culture positive for Mycobacterium tuberculosis. Two HRQoL questionnaires translated into Yoruba were self-administered. Chest X-ray and Aspergillus IgG were collected at each visit. RESULTS: A total of 204 participants were recruited into this study. Most (70.6%) were age 18-39 years, and only 3.9% were above 60 years; 66.7% of all participants were males. A total of 189 (92.6%) participated in the 3-month assessment, 174 (85.3%) at 6 months, 139 (68.1%) at 9 months, and 99 (48.5%) at 12 months. At baseline, only 60.9% scored "good" or "very good" QoL and health on the WHOQOL-Bref, which improved to 77% at 6 months. At baseline, 10.4% had positive Aspergillus IgG levels, 15.1% at 3 months, 11.5% at 6 months, 16.7% at 9 months, and 19.3% at 12 months. Those with a positive Aspergillus IgG at 6 months had worse physical health (p = 0.001), psychological state (p = 0.002), social relationships (p = 0.006), and environmental QoL (p = 0.001) domains of the WHOQOL-Bref. Probable CPA was 10.4% at baseline and 19.3% at 6 months post-PTB therapy. Thirty-eight (18.6%) relocated after 6 months of treatment, 16 (7.8%) were lost to follow-up, and 11 (5.4%) died. CONCLUSION: Our findings reveal a significant relationship between the QoL and Aspergillus IgG levels of TB patients. Further follow-up studies and additional imaging are required to determine when patients develop CPA and its clinical impact.

Enhancing the multi-dimensional assessment of quality of life: introducing the WHOQOL-Combi.

INTRODUCTION: We revisited the global concept of subjective quality of life (QoL) as assessed by the WHOQOL-BREF to investigate whether it could be elaborated into a conceptually more comprehensive instrument with good psychometric properties. Responding to a growing need for shorter QoL measures with broader social, spiritual and environmental contents, facets from WHOQOL international modules were examined for potential integration into the new WHOQOL-Combi. METHOD: Adults over 65 years, diagnosed with one or more chronic diseases (n = 2833), completed 41 WHOQOL items during the CLASSIC survey; each item represented a WHOQOL facet. This pool of specific QoL facets contained 24 from the WHOQOL-BREF (excluding general items), and 17 from recent international WHOQOL short-form modules, selected for their generic properties. Rasch modelling reduced the final item pool when assessing the WHOQOL-Combi's conceptual structure. Comparisons are made with the WHOQOL-BREF. RESULTS: Modelling confirmed the tenability of a 36-item solution scored as a five-domain profile, comprised of 24 WHOQOL-BREF facets and 12 new facets from modules. Social and psychological domains were strengthened by three facets, spiritual QoL by five, and physical QoL by one. The WHOQOL-Combi showed sound model fit, excellent internal consistency (α = .95), and scores discriminated between socio-demographic categories. Concurrent validity with the EQ-5D-5L was confirmed for physical and psychological domains. Performance was similar to the WHOQOL-BREF. CONCLUSION: The WHOQOL-Combi offers a contemporary, comprehensive, integrated, multi-dimensional subjective QoL instrument with enhanced evaluations of social, spiritual, psychological and physical QoL. Acceptable to older people, future research should evaluate younger age groups and other cultures.

Development of a measure for patients preparing to start dialysis and their partners: The Starting Dialysis Questionnaire (SDQ).

BACKGROUND: The transition onto dialysis is a stressful time that affects both patients and their partners. Research suggests that psychological and interpersonal characteristics within the couple are related to how well they adapt to dialysis. The aim of this multi-phase, mixed methods study was to develop a measure, the Starting Dialysis Questionnaire (SDQ), that is applicable to both patients and their partners and assesses their own thoughts and feelings about these constructs. METHODS: Data from semi-structured interviews with patients and their partners (n = 22 couples) were analysed using theoretical thematic analysis to identify and define constructs related to quality of life (QOL). Next, items addressing these constructs were derived from the interviews. Then, cognitive interviews were conducted with patients with chronic kidney disease and their partners (n = 5 couples) to assess the face validity and comprehensibility of the items. Lastly, preliminary psychometric properties were evaluated in a sample of patients preparing to start dialysis and their partners (n = 83 couples). RESULTS: Three themes related to QOL were identified, namely dialysis expectations, accepting dialysis and dyadic relationship characteristics. The cognitive interviews refined the SDQ and established its face validity. Psychometric assessments indicated that overall the items performed well and did not show significant floor or ceiling effects. Good internal consistency was found within the three domains, and items correlated within the domains. CONCLUSIONS: The SDQ is a measure (34 items) that assesses key psychological and interpersonal factors in patients and their partners as they start dialysis. It shows good preliminary psychometric properties; however, a large-scale field trial is needed to establish its validity. Once validated, it could offer a clinically useful tool to assist clinicians in preparing patients and partners for dialysis.

Is Culture Important to the Relationship Between Quality of Life and Resilience? Global Implications for Preparing Communities for Environmental and Health Disasters.

BACKGROUND: Using a preventative approach, we investigated whether international subjective qualities of life are associated with resilience to adversity when culture is taken into account. Although resilience has been previously associated with good QoL, cross-cultural studies are scarce. METHODS: Sequential linear multiple regression models of WHOQOL SRPB data from 15 countries worldwide (N = 3,019) examined which qualities are most closely associated with resilience, when adjusting for culture and selected demographics. We also examined whether all cultures confirmed this positive association. Of 13 QoL facets identified from a literature summary, seven were associated with defining resilience and six reflected strategies for building resilience; these were tested together. Principal components analysis provided a dependent variable for resilience, covering inner strength and hope. RESULTS: The final model explained 52% of resilience overall, of which QoL explained 37% and culture explained 12% (p < 0.0001). Being older than 45 years was a significant covariate. Spiritual QoL from meaning in life, awe and wonder, wholeness and integration, and being kind to others was linked with strategies for building resilience (28%). Better psychological QoL from high levels of positive feelings and low negative feelings was associated with defining resilience (9%). Larger significant positive ß's were found for 10 cultures, so model "universality" was not confirmed. CONCLUSION: A new cross-cultural psycho-spiritual model of resilience is presented. Assessing individual QoL profiles could identify suitable community members to build resilience locally in culturally acceptable styles. The WHOQOL SRPB evidence could inform international policy designed to prepare vulnerable cultures that are threatened with environmental and health disasters.

Community asset participation and social medicine increases qualities of life.

RATIONALE: Social prescribing to community assets, like social groups, is a current policy goal. As aging adults lead longer, healthier lives, the effects of participating in community assets raises questions about whether subjective quality of life (QoL) improves during participation and on what dimensions. OBJECTIVE: The study's goal was to examine the effectiveness of community assets at improving QoL among older people living in the community. METHOD: Examining longitudinal survey data which tracked health and wellbeing in older adults living in Salford, UK over 12 months, we first used regressions on community assets to compare the World Health Organization's QoL Assessment (WHOQOL-BREF) domains at baseline for those who already participated in community assets (54%) and with non-participants (46%). Second, we used propensity score matching to compare QoL in an 'uptake' group (no initial participation but who participated at 12 months), to those who never participated, and to a 'cessation' group who participated initially, but ceased within one year, to those who always participated. RESULTS: Group comparisons confirmed that participants reported significantly higher QoL on all domains - environmental, psychological, physical, and social QoL - and on 16 predicted facets. After affirming group matching reliability, the strongest results were for the uptake group, with significant improvements in all domains, and in 18 facets. All QoL domains decreased in the cessation group, but overall, the effect was weaker. As predicted from the context, QoL relating to 'opportunities for recreation and leisure' showed the greatest effect. Furthermore, QoL increased with uptake, and decreased with cessation. CONCLUSION: Policies to improve QoL in later life should be designed not just to promote community assets, but also maintain participation once initiated.

Does quality of life feedback promote seeking help for undiagnosed cancer?

PURPOSE: Diagnosing cancer early is an imperative, as help-seeking delays affect survival. Quality of life (QoL) deteriorates after diagnosis, but decline may start when cancer is suspected at the earliest stage of the pathway to treatment. This study examined whether offering guided feedback about personal QoL to adults with potential cancer symptoms, living in deprived communities, changes QoL and promotes help-seeking in primary care. METHODS: Visitors to a CRUK mobile cancer roadshow were recruited in 43 sites. A prospective longitudinal (2 × 2) repeated-measures design was applied. Where they presented a potential cancer symptom, and were 'signposted' to a GP, they were allocated to a symptom condition, or a lifestyle condition, if seeking cancer risk advice. Randomisation was to an Intervention group, who received feedback about personal QoL results (WHOQOL-BREF and WHOQOL importance measures), or a Control group who assessed QoL without feedback. Depression was screened. RESULTS: Of 107 participants, the mean age was 53; 50% were women, 57% were without tertiary education, 66% were unemployed and 45% were currently ill. Over 10 weeks, 54% of all those with symptoms sought help from a medical source and 42% specifically from a GP. Thirty-one completed all three assessments. With symptoms present, psychological, social and environmental QoL were poor, becoming poorer over time. When the symptoms group received feedback, psychological QoL increased, but GP visits were unaffected. However, feedback increased help-seeking from informal social contacts. Lifestyle groups reported consistently good psychological and social QoL. CONCLUSION: This early cancer research offers practical and theoretical implications for QoL interventions in deprived communities.

What Do U.K. Orthopedic Surgery Patients Think About PROMs? Evaluating the Evaluation and Explaining Missing Data.

The NHS routinely evaluates the quality of life of patients receiving hip or knee replacement surgery using patient-reported outcome measures (PROMs), but some hospital completion rates are only 30%, restricting data usefulness. Statistics limit insights into how and why data are missing, so qualitative methods were used to explore this issue. Observation periods preceded semistructured interviews with 34 preoperative patients attending an orthopedic outpatient clinic. Interview themes covered: completion time/timing, orientation, setting, measures, and practicalities. Triangulated against observations, pragmatic barriers, and facilitators were considered. Refined themes included completion conditions, patient support, and national delivery. Simple improvements (e.g., quiet zone) could improve completion rates and reducing missing data. Reorganizing preoperative leaflets and their systematic distribution via standardized procedures could reassure patients, enhancing PROMs acceptance, while reducing inquiries and subsequent staff burden. Findings have implications for interpreting national statistics. They indicate that further debate about mandating preoperative PROMs is due.

Is there an association between isotretinoin therapy and adverse mood changes? A prospective study in a cohort of acne patients.

Background: Treatment with isotretinoin has been associated with adverse mood changes. However, even though a number of studies support this association, others refute it, and a concrete causal link has yet to be proven. Acne itself is associated with depressive symptoms, thus making studies on the topic difficult to design and interpret. Objectives and methods: Using validated tools, we performed a prospective study in order to assess the effects of treatment with isotretinoin on the mood of patients with acne vulgaris. Results: Fifty-six patients were included with a mean age of 21 years. At baseline, questionnaire scores for all measured parameters were indicative of lower mood than published norms. During and after treatment, values of either stable or improving mood were displayed across all questionnaires. Three patients developed significantly deteriorating moods, two of whom also experienced severe physical adverse effects. Conclusion: The relationship between isotretinoin and depression is the most debated aspect of isotretinoin therapy. Our results link isotretinoin to an overall improvement in psychological wellbeing, even in patients suffering with stable mental illness. However, we also found that a small minority of patients are susceptible to severe mood deterioration, particularly in conjunction with severe physical side effects.

Undiagnosed cancer symptoms in the community: does poor quality of life influence the decision to seek help?

PURPOSE: Although a cancer diagnosis is linked with decrements to quality of life (QoL), it is unknown exactly when QoL starts to deteriorate, and whether this occurs during the pre-diagnostic pathway. This study aimed to examine QoL during this phase, and in addition investigate whether QoL levels influence decisions about seeking professional help. This is important, because early diagnosis is linked to lower cancer mortality rates. METHODS: Working alongside a Cancer Research UK Roadshow in socially deprived communities, the recent QoL of adult visitors was assessed, before attending primary care. Using a cross-sectional design, we compared QoL in those presenting a potential cancer symptom/sign, with others seeking lifestyle advice to reduce cancer risk. Self-reported QoL (WHOQOL-BREF), and intention to seek help, were measured. RESULTS: Of 107 recruited, 50% were men. The potential cancer symptom group reported significantly poorer general QoL and psychological QoL, than lifestyle controls. Prior poorer physical QoL predicted stronger intentions to consult a general practitioner (GP) in the next 2 weeks, when controlling for symptom presence. CONCLUSIONS: QoL is poorer for those with potential cancer symptoms, before they first seek advice from primary care. Poorer physical QoL is associated with stronger intentions to make a GP appointment. An implication for longer term health is that if public awareness about the impact of symptoms on QoL was raised, this could provide an impetus to seek help.

How will the sustainable development goals deliver changes in well-being? A systematic review and meta-analysis to investigate whether WHOQOL-BREF scores respond to change.

INTRODUCTION: The Sustainable Development Goals (SDGs) 2015 aim to '…promote well-being for all', but this has raised questions about how its targets will be evaluated. A cross-cultural measure of subjective perspectives is needed to complement objective indicators in showing whether SDGs improve well-being. The WHOQOL-BREF offers a short, generic, subjective quality of life (QoL) measure, developed with lay people in 15 cultures worldwide; 25 important dimensions are scored in environmental, social, physical and psychological domains. Although validity and reliability are demonstrated, clarity is needed on whether scores respond sensitively to changes induced by treatments, interventions and major life events. We address this aim. METHODS: The WHOQOL-BREF responsiveness literature was systematically searched (Web of Science, PubMed, EMBASE and Medline). From 117 papers, 15 (24 studies) (n=2084) were included in a meta-analysis. Effect sizes (Cohen's d) assessed whether domain scores changed significantly during interventions/events, and whether such changes are relevant and meaningful to managing clinical and social change. RESULTS: Scores changed significantly over time on all domains: small to moderate for physical (d=0.37; CI 0.25 to 0.49) and psychological QoL (d=0.22; CI 0.14 to 0.30), and small for social (d=0.10; CI 0.05 to 0.15) and environmental QoL (d=0.12; CI 0.06 to 0.18). More importantly, effect size was significant for every domain (p<0.001), indicating clinically relevant change, even when differences are small. Domains remained equally responsive regardless of sample age, gender and evaluation interval. CONCLUSION: International evidence from 11 cultures shows that all WHOQOL-BREF domains detect relevant, meaningful change, indicating its suitability to assess SDG well-being targets.

Effect of health literacy on the quality of life of older patients with long-term conditions: a large cohort study in UK general practice.

PURPOSE: The levels of health literacy in patients with long-term conditions (LTCs) are critical for better disease management and quality of life (QoL). However, the impact of health literacy on QoL in older adults with LTCs is unclear. This study examined the association between health literacy and domains of QoL in older people with LTCs, investigating key socio-demographic and clinical variables, as confounders. METHODS: A prospective cohort study was conducted on older adults (n = 4278; aged 65 years and over) with at least one LTC, registered in general practices in Salford, UK. Participants completed measures of health literacy, QoL, multi-morbidity, depression, social support, and socio-demographic characteristics. Multivariate linear regressions were performed to examine the effects of health literacy on four QoL domains at baseline, and then changes in QoL over 12 months. RESULTS: At baseline, poor health literacy was associated with lower scores in all four QoL domains (physical, psychological, social relationships and environment), after adjusting for the effects of multi-morbidity, depression, social support and socio-demographic factors. At 12-month follow-up, low health literacy significantly predicted declines in the physical, psychological and environment domains of QoL, but not in social relationships QoL. CONCLUSIONS: This is the largest, most complete assessment of the effects of health literacy on QoL in older adults with LTCs. Low health literacy is an independent indicator of poor QoL older patients with LTCs. Interventions to improve health literacy in older people with LTCs are encouraged by these findings.

Evaluating a new methodology for providing individualized feedback in healthcare on quality of life and its importance, using the WHOQOL-BREF in a community population.

PURPOSE: We conducted an evaluation to find out how a novel quality of life (QoL) intervention containing guided individualized feedback was appraised. The importance of QoL was matched with QoL assessment for each subjective dimension, using graphical feedback. We examined whether this information was acceptable, feasible and valued beyond the clinical context, among the community. METHODS: Using a mixed-methods cross-sectional design, the intervention was piloted with 129 participants from communities and registered in primary care. WHOQOL-BREF and WHOQOL Importance scores were graphically matched by dimension. Results were inspected and interpreted with directed guidance to identify good and poor QoL. We report the post-intervention evaluation of feedback, including qualitative themes. Follow-up interviews among those expecting feedback to be helpful explored potential self-management and healthcare uses. RESULTS: After feedback, 65 % reported changes in thoughts and perceptions of QoL, often describing insights as self-affirming. Goals or expectations changed for 34 %, and motivation to change was reported. Over 50 % evaluated the feedback as helpful in the short term or for the future. Follow-up interviews endorsed the value of the feedback and its usefulness in sharing with a healthcare professional (92 %), suggesting it would facilitate professionals' understandings of patients and enable health advice to be targeted. CONCLUSIONS: The benefits of using this novel feedback can be extended to the general population, as directed guidance aids interpretation, thereby saving health service costs. This complex pilot intervention needs testing in a blinded fully randomized controlled trial. Beyond independent self-management, graphs could be used during clinical decision-making.

Family and professionals underestimate quality of life across diverse cultures and health conditions: systematic review.

OBJECTIVES: To examine how accurately proxies evaluate quality of life (QoL) in people they know, using cross-cultural data from the multidimensional, multilingual World Health Organization Quality of Life assessment short-form (the WHOQOL-BREF) and whether accuracy varies by health condition or proxy type (eg, family/professional). STUDY DESIGN AND SETTING: Systematic review with meta-analysis: We searched five databases for reports of proxy-completed WHOQOL-BREF scores and aggregated results using a random-effects model. Minimal clinically important difference values were calculated. RESULTS: Analyses included nine studies (1980 dyads) of physical (n = 762) or mental (n = 604) health conditions, or intellectual disability (n = 614), in 10 countries. Mean person-proxy correlations ranged from 0.28 (social QoL) to 0.44 (physical QoL). Proxy measures were underestimates (ie, significantly lower than persons reported for themselves) for social [mean difference (MD) = 4.7, 95% confidence interval (CI): 1.8, 7.6], psychological (MD = 3.7, 95% CI: 0.6, 6.8), and physical (MD = 3.1, 95% CI: 0.6, 5.6) QoL. Underestimates varied significantly between health conditions for social (P < 0.001), psychological (P = 0.009), and physical (P = 0.02) QoL. Family members assessed psychological and environmental QoL better than professionals. CONCLUSION: Proxies tend to be imprecise, underestimating QoL, and should be aware of this tendency. Where health care is decided for others, family members' views about QoL should be prioritized.

Using guided individualised feedback to review self-reported quality of life in health and its importance.

This pilot study investigated the effects of providing guided, individualised feedback on subjective quality of life (QoL), using results from the multidimensional WHOQOL-BREF profile. Participants (n = 129; 85 chronically ill) were recruited in the community, and primary care. They were randomised to receive written or verbal guidance on interpreting a new graphical summary profile, which simultaneously presented (a) their individual self-ratings of QoL and (b) the importance attributed to each QoL dimension. Before and after feedback, participants completed health status, subjective QoL, QoL Importance, goal-oriented QoL and mood measures. Receiving individualised feedback was associated with increased psychological QoL, with modest effect size. No effects were found for physical, social or environmental QoL or QoL importance, health status, mood or goal-oriented QoL. There were no differences between modes of delivering guidance, indicating equal effectiveness. Chronic illness participants reported poorer QoL, moved more slowly towards their QoL goals, and had larger differences between core QoL and QoL Importance than healthy participants. Guided individualised empirical feedback about QoL judgements could be used to promote psychological well-being. Although professional interpretation of feedback is unnecessary, if shared, patients' profiled WHOQOL information could support self-monitoring, self-management and clinical decision-making.

WHOQOL Pain and Discomfort Module: development and validity testing of the Italian version.

BACKGROUND: The World Health Organization Quality of Life scale Pain and Discomfort Module (WHOQOL PDM) was designed to assess quality of life (QoL) in adults with chronic pain. It comprises 16 items covering four facets of pain: relief, anger/frustration, vulnerability/fear/worry, and uncertainty. AIM: The purpose of this study was to validate the Italian version of the WHOQOL PDM. METHODS: Chronic pain was assessed in 400 patients using the WHOQOL PDM and other pain scales, together with scales measuring associated symptoms, depression, anxiety, and QoL. RESULTS: The WHOQOL PDM shows good internal consistency, concurrent validity (it was significantly associated with all the WHOQOL BREF domains), construct validity (it was significantly associated with other pain scales), and discriminant validity (there were significant differences among different groups of patients). CONCLUSIONS: The Italian version of the WHOQOL PDM is a brief, useful, and valid tool for assessing chronic pain and its impact on patients' QoL.

Introducing the WHOQOL-SRPB BREF: developing a short-form instrument for assessing spiritual, religious and personal beliefs within quality of life.

PURPOSE: The aim was to develop and conduct preliminary testing of a short-form measure to assess spiritual, religious and personal beliefs (SRPB) within quality of life (QoL). METHODS: Existing data from the 132 items of the WHOQOL-SRPB (n = 5087) obtained in 18 cultures were first analysed to select the 'best' performing item from each of the eight SRPB facets. These were integrated with the 26 WHOQOL-BREF items to give 34 items in the WHOQOL-SRPB BREF. A focus group of hospital chaplains reviewed this new short-form. The WHOQOL-SRPB BREF was administered to a UK community sample (n = 230) either with an adapted WHOQOL-SRPB Importance measure or the SWBQ. A subset received both WHOQOL measures twice. RESULTS: Completed in 8 mins, the WHOQOL-SRPB BREF was acceptable and feasible; Importance 5.5 mins. Good internal consistency reliability was found overall (α = 0.85), for the SRPB domain (α = 0.83), and Importance (α = 0.90). Domains were moderately correlated. Domain test-retest reliability was acceptable in both WHOQOL measures, except for SRPB Importance. Sleep was linked with religious beliefs. Hope and wholeness were widely associated with non-spiritual facets. Factor analysis (maximum likelihood) of items largely confirmed the WHOQOL domain structure, adding SRPB as a significant fifth domain. Internally, SRPB distinguished religious from existential beliefs, and was validated by association with personal and transcendental well-being from the SWBQ. CONCLUSION: Preliminary evidence shows that the WHOQOL-SRPB BREF is sound for use in, and beyond health care. Extracted from a measure already available in 18 languages, this short-form can be immediately used where such translations exist.

A systematic review to quantitatively evaluate 'Stepping Stones': a participatory community-based HIV/AIDS prevention intervention.

This first independent systematic review examined evidence for the effectiveness of the stepping stones intervention in HIV prevention. To reduce HIV transmission it addresses gender roles and promotes equitable relationships. Biomedical, behavioural and psychosocial outcomes extracted from six databases and 'grey' literature identified eight reports of seven studies (n = 14,630) from India, Gambia, S. Africa, Ethiopia, Angola, Tanzania, Uganda and Fiji. Infection incidence tested in the only RCT showed no significant reduction in HIV, although HSV-2 decreased. Condom use increased (two countries out of eight). Risk reduction results were mixed for declining alcohol misuse (two studies in three) and multiple partners (one in two). Communicating HIV information to partners, family or community improved (three studies from seven). Gender inequity was reduced in India (one in five), but stigma decreased in four studies. Future investigations of diverse cultures and older adults should select high quality biomedical and quality of life measures.

Expecting a good quality of life in health: assessing people with diverse diseases and conditions using the WHOQOL-BREF.

BACKGROUND AND OBJECTIVES: Fulfilling patient expectations is central to defining a good quality of life (QoL) in health. The WHOQOL-BREF was developed using novel, person-centred methods and is a generic patient-reported outcomes measure (PROM). However, without robust psychometric performance, PROMs cannot be relied upon to assess individuals. This study investigated the WHOQOL-BREF (UK), with this use in mind. DESIGN: Cross sectional with nested repeated measures. SETTING AND PARTICIPANTS: Twenty-seven disease groups or health conditions and healthy people were recruited at 38 UK sites, in a wide range of settings (n = 4628). INTERVENTIONS: 'Treatment as usual'; new and alternative interventions. OUTCOME MEASURES: WHOQOL-BREF (UK); SF-36. RESULTS: Respondent burden was low, as acceptability and feasibility were high. Internal consistency was excellent (0.92) and test-retest reliability good. Distinctive QoL profiles were found for diverse conditions. Musculoskeletal, psychiatric and cardiovascular patients reported the poorest QoL and also improved most during treatment. Overall, QoL was good, and best for healthy groups, supporting discriminant validity. Compared with the SF-36, WHOQOL physical and psychological domains showed good concurrent validity, although social was weak. Small or moderate effect sizes confirmed responsiveness to change in specified domains for certain conditions and interventions. Age had a small impact on reporting QoL. DISCUSSION AND CONCLUSION: The WHOQOL-BREF is found to be a high quality patient-centred generic tool suited to individual assessment in clinics, for research, and audit.
