RESUMEN

In a randomized controlled trial in the Netherlands, we studied the (cost)effectiveness of adding a mindful yoga intervention (MYI+TAU) to treatment as usual (TAU) for young women with major depressive disorder (MDD). In this paper, we present the results of the economic analyses. Societal costs and health outcomes were prospectively assessed during 15 months for all randomized participants (n = 171). Symptoms of depression (Depression Anxiety and Stress Scales; DASS) and quality adjusted life years (QALYs) were used as health outcomes in the economic analyses. Mean total societal costs during the 15 months of the study were €11.966 for the MYI+TAU group and €13.818 for the TAU group, differences in mean total societal costs were not statistically significant. Health outcomes (DASS and QALY) were slightly in favour of MYI+TAU, but differences between groups were not statistically significant. Combining costs and health outcomes in cost-effectiveness analyses indicated that MYI+TAU is likely to be cost-effective compared to TAU which was confirmed by sensitivity analyses. Although there were limitations in the cost-effectiveness analysis, findings from this study suggest that MYI+TAU warrants future attention for the potential to be cost-effective compared to TAU for young women with MDD.

RESUMEN

INTRODUCTION: Social functioning is often impaired during the ultra-high risk (UHR) phase for psychosis, but group-level studies regarding the role of social functioning in transition to psychosis are inconsistent. Exploring the inter-individual differences which underlie the association between social functioning and psychotic symptoms in this phase could yield new insights. OBJECTIVE: To examine the idiographic and dynamic association between social activation and suspiciousness in individuals at UHR for psychosis using time-series analysis. METHODS: Twenty individuals at UHR for psychosis completed a diary application every evening for 90 days. Two items on social activation (quantity: 'time spent alone' and quality: 'feeling supported') and two items on suspiciousness ('feeling suspicious' and 'feeling disliked') were used. Time series (T = 90) of each individual were analyzed using vector auto regression analysis (VAR), to estimate the lagged (over 1 day) effect of social activation on suspiciousness, and vice versa, as well as their contemporaneous associations. RESULTS: Heterogeneous person-specific associations between social activation and suspiciousness were found in terms of strength, direction and temporal aspects. CONCLUSIONS: The association between social activation and suspiciousness differs amongst individuals who are at UHR for psychosis. These findings underline the importance of tailoring psychosocial interventions to the individual. Future studies may examine whether using results of single-subject studies in clinical practice to personalize treatment goals leads to better treatment outcomes.

RESUMEN

BACKGROUND: Social cognitive impairment is a recognized feature of psychotic disorders. However, potential age-related differences in social cognitive impairment have rarely been studied. STUDY DESIGN: Data came from 905 individuals with a psychotic disorder, 966 unaffected siblings, and 544 never-psychotic controls aged 18-55 who participated in the Genetic Risk and Outcome of Psychosis (GROUP) study. Multilevel linear models were fitted to study group main effects and the interaction between group and age on emotion perception and processing (EPP; degraded facial affect recognition) and theory of mind (ToM; hinting task) performance. Age-related differences in the association between socio-demographic and clinical factors, and EPP and ToM were also explored. STUDY RESULTS: Across groups, EPP performance was associated with age (ß = -0.02, z = -7.60, 95% CI: -0.02, -0.01, P < .001), with older participants performing worse than younger ones. A significant group-by-age interaction on ToM (X2(2) = 13.15, P = .001) indicated that older patients performed better than younger ones, while no age-related difference in performance was apparent among siblings and controls. In patients, the association between negative symptoms and ToM was stronger for younger than older patients (z = 2.16, P = .03). CONCLUSIONS: The findings point to different age-related performance patterns on tests of 2 key social cognitive domains. ToM performance was better in older individuals, although this effect was only observed for patients. EPP was less accurate in older compared with younger individuals. These findings have implications with respect to when social cognitive training should be offered to patients.

RESUMEN

Personal recovery transcends illness and is a unifying human experience. Core elements in personal recovery are hope, meaning, and rebuilding oneself. Here we aim to investigate whether factors associated with personal recovery in patients with non-affective psychosis, unaffected siblings and healthy controls are similar. We investigated the association between personal recovery and resilience, social support, socio-demographic and illness-related variables in 580 patients, 630 siblings, and 351 healthy controls who participated in the Genetic Risk and Outcome of Psychosis (GROUP) study. Bi-variate associations between personal recovery and individual variables were assessed and multiple linear regression analyses were performed to estimate the proportion of variance in personal recovery that could be accounted for by the predictors and to investigate which predictors independently added to the model. Positive self was significantly and independently associated with personal recovery in all three groups. Pro-active action taking also seems to be important. Social functioning significantly contributed to explained variance in patients and siblings. Regarding illness-related factors, depressive symptoms had impact on personal recovery in both patients and siblings, whereas positive symptoms only did in siblings. The findings imply that not only personal recovery itself, but also some associated factors are universally human and suit us all. This means that patients and non-patients share supportive factors of personal recovery which may help to reach mutual understanding. Recovery-oriented practices and mental health services might be more effective when focusing also on improving self-image, functional coping styles and generating social interaction, next to the reduction of affective symptoms.

RESUMEN

INTRODUCTION: An updated summary of the most used instruments assessing auditory hallucinations in population with psychosis, allows us to underline the scarceness and need of Spanish versions of important instruments. The aim of the study is to examine the psychometric characteristics of two different and complementary instruments for assessing auditory hallucinations, the Spanish version of the Auditory Vocal Hallucination Scale (AVHRS) and the Spanish version of the Positive and Useful Voices Inquiry (PUVI). MATERIALS AND METHODS: A sample of 68 patients from four different centres, with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder presenting with auditory hallucinations were included. Apart from the AVHRS and the PUVI, the Psychotic Symptom Rating Scales-Auditory Hallucinations subscale (PSYRATS-AH) and the Positive and Negative Syndrome Scale (PANSS) were also administered to all patients, plus an acceptability questionnaire. RESULTS: The Spanish version of the AVHRS showed a good internal consistency, a moderate to high inter-rater reliability, a medium to moderate test-retest reliability, and a good convergent and discriminant validity. The Spanish version of the PUVI showed a good internal consistency and a heterogeneous, but in general moderate, test-retest reliability. CONCLUSIONS: The Spanish versions of the AVHRS and the PUVI have good psychometric properties and are well accepted among patients.

Introducción: Un resumen actualizado de los instrumentos más utilizados en la evaluación de las alucinaciones auditivas en poblaciones con psicosis, nos permite subrayar la escasez y necesidad de versiones españolas de importantes instrumentos. El objetivo del estudio es examinar las características psicométricas de dos instrumentos para la evaluación de las alucinaciones auditivas diferentes y complementarios, la versión española de la Escala de Valoración de Alucinaciones Auditivas Vocales (AVHRS) y la versión española de la Encuesta sobre Voces Positivas y Útiles (PUVI). Material y métodos: Se incluyó una muestra de 68 pacientes de cuatro centros diferentes, con diagnóstico de esquizofrenia o trastorno esquizoafectivo según el DSM-IV, que presentaban alucinaciones auditivas. Además de la AVHRS y de la PUVI, se administraron también a todos los pacientes la subescala de Alucinaciones Auditivas de la Escalas de Evaluación de Síntomas Psicóticos (PSYRATS-AH) y la Escala de Evaluación de Síndrome Positivo y Negativo (PANSS), además de un cuestionario de aceptabilidad. Resultados: La versión española de la AVHRS mostró una buena consistencia interna, una fiabilidad inter-jueces de moderada a alta, una fiabilidad re-test de media a moderada, y una buena validez convergente y discriminante. La versión española de la PUVI mostró una buena consistencia interna y una fiabilidad test-retest heterogénea pero, en general, moderada. Conclusiones: Las versiones españolas de la AVHRS y la PUVI tienes buenas propiedades psicométricas y son bien aceptadas entre los pacientes. (AU)

RESUMEN

INTRODUCTION: Antipsychotics (APs) can cause weight gain. Little is known about changes in weight when APs are combined with other psychotropics. This study examines the weight change in patients undergoing long-term treatment with APs or with AP combined with other psychotropics. METHODS: Patients with non-affective psychotic disorder from the GROUP study were divided into three groups: AP medication group (APm) (n = 100), AP in combination with other psychotropics (APc) (n = 73), and medication-free (Meds-free) (n = 100). Weight change was examined at inclusion and after three years using a paired-sample t-test. An Independent-sample t-test was performed to evaluate weight change among patients taking clozapine, olanzapine, and quetiapine and individuals not taking these medications. Linear regression was performed to evaluate the association between covariates and weight. RESULTS: Patients in the APm group [mean = 1.800 kg, t(99)=2.849, 95% CI(0.546, 3.054), p = 0.005] and the APc group [mean = 1.877 kg, t(72)=2.688, 95% CI(0.485, 3.268), p = 0.009] showed significant weight gain. Patients taking clozapine, olanzapine or quetiapine showed significant weight gain compared to those not taking these medications [mean difference=1.707 kg, t(271)= 2.061, 95% CI(0.077, 3.337), p = 0.040)]. CONCLUSION: Patients receiving APs and APs with other psychotropics gain weight during long-term treatment. It is possible that weight gain is mainly driven by APs.

RESUMEN

BACKGROUND AND HYPOTHESIS: Recovery from psychosis is a complex phenomenon determined by an array of variables mutually impacting each other in a manner that is not fully understood. The aim of this study is to perform an approximated replication of a previous network analysis study investigating how different clinical aspects-covering psychopathology, cognition, personal resources, functional capacity, and real-life functioning-are interrelated in the context of schizophrenia-spectrum disorders. STUDY DESIGN: A sample of 843 subjects from a multisite cohort study, with the diagnosis of a schizophrenia-spectrum disorder, was used to estimate a network comprising 27 variables. The connectivity and relative importance of the variables was examined through network analysis. We used a quantitative and qualitative approach to infer replication quality. STUDY RESULTS: Functional capacity and real-life functioning were central and bridged different domains of the network, in line with the replicated study. Neurocognition, interpersonal relationships, and avolition were also key elements of the network, in close relation to aspects of functioning. Despite significant methodological differences, the current study could substantially replicate previous findings. CONCLUSIONS: Results solidify the network analysis approach in the context of mental disorders and further inform future studies about key variables in the context of recovery from psychotic disorders.

RESUMEN

BACKGROUND: Substance use is overrepresented in patients with psychosis. Maladaptive coping has been proposed as one of the mechanisms which might underlie this high prevalence. Patients are known to apply more maladaptive coping compared to the healthy population. However, it is unknown whether coping is associated with the use of different substances across those with different vulnerability for psychosis, and whether coping mediates the possible association between life events and substance use. METHODS: In this multicenter, cohort study, 429 patients, 504 siblings, and 220 controls were included. We determined whether coping was associated with tobacco smoking, cannabis use, or alcohol consumption. Multivariable logistic regression models were applied whilst correcting for potential confounders. We performed post-hoc analyses to explore the association between negative life events, tobacco smoking, and the role of coping as a mediator in patients with psychosis. RESULTS: A positive association was found in patients between passive coping and tobacco smoking (fully adjusted OR 1.65, 95% CI 1.18-2.31). Tobacco smoking patients experienced more negative life events compared to non-smoking patients and passive coping mediated this association. In siblings and controls, none of the coping strategies were associated with substance use. CONCLUSIONS: The coping style of patients with psychosis is associated with tobacco smoking and mediates the association between negative events and tobacco smoking. No significant associations were found in siblings, controls or concerning other substance use. Future research is required to examine whether enhancing healthy coping strategies decreases tobacco use in patients with psychosis.

RESUMEN

BACKGROUND: The prevalence of psychotic experiences (PEs) is higher in low-and-middle-income-countries (LAMIC) than in high-income countries (HIC). Here, we examine whether this effect is explicable by measurement bias. METHODS: A community sample from 13 countries (N = 7141) was used to examine the measurement invariance (MI) of a frequently used self-report measure of PEs, the Community Assessment of Psychic Experiences (CAPE), in LAMIC (n = 2472) and HIC (n = 4669). The CAPE measures positive (e.g. hallucinations), negative (e.g. avolition) and depressive symptoms. MI analyses were conducted with multiple-group confirmatory factor analyses. RESULTS: MI analyses showed similarities in the structure and understanding of the CAPE factors between LAMIC and HIC. Partial scalar invariance was found, allowing for latent score comparisons. Residual invariance was not found, indicating that sum score comparisons are biased. A comparison of latent scores before and after MI adjustment showed both overestimation (e.g. avolition, d = 0.03 into d = -0.42) and underestimation (e.g. magical thinking, d = -0.03 into d = 0.33) of PE in LAMIC relative to HIC. After adjusting the CAPE for MI, participants from LAMIC reported significantly higher levels on most CAPE factors but a significantly lower level of avolition. CONCLUSION: Previous studies using sum scores to compare differences across countries are likely to be biased. The direction of the bias involves both over- and underestimation of PEs in LAMIC compared to HIC. Nevertheless, the study confirms the basic finding that PEs are more frequent in LAMIC than in HIC.

RESUMEN

OBJECTIVE: To examine the added value of a 9-week mindful yoga intervention (MYI) as add-on to treatment as usual (TAU) in reducing depression for young women (18-34 years) with major depressive disorder (MDD). METHOD: Randomized controlled trial (RCT; n = 171) comparing TAU + MYI with TAU-only. Assessments were at baseline, postintervention, and at 6- and 12-month follow-up. Primary outcome measures were clinician-rated and self-reported symptoms of depression, together with a diagnostic interview to establish MDD diagnosis that was restricted to the baseline and 12-month follow-up assessments. Quality of life in various domains was assessed as secondary outcome measure. As potential mediators for treatment efficacy, we included self-report measures of rumination, self-criticism, self-compassion, intolerance of uncertainty, perceived body awareness and dispositional mindfulness, together with behavioral measures of attentional bias (AB) and depression-related self-associations. RESULTS: Adding MYI to TAU did not lead to greater reduction of depression symptoms, lower rate of MDD diagnosis or increase in quality of life in various domains of functioning at post and follow-up assessments. There were no indirect effects through any of the potential mediators, with the exception of self-compassion. CONCLUSION: Adding MYI to TAU appeared not more efficacious than TAU-only in reducing depression symptoms in young women. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

PURPOSE: This study examines satisfaction with social connectedness (SSC) as predictor of positive and negative symptoms in people with a psychotic disorder. METHODS: Data from the Pharmacotherapy Monitoring and Outcome Survey (PHAMOUS) was used from patients assessed between 2014 and 2019, diagnosed with a psychotic disorder (N = 2109). Items about social connectedness of the Manchester short assessment of Quality of Life (ManSA) were used to measure SSC. Linear mixed models were used to estimate the association of SSC with the Positive and Negative Syndrome Scale (PANSS) after one and two years against α = 0.01. Analyses were adjusted for symptoms, time since onset, gender and age. Additionally, fluctuation of positive and negative symptom scores over time was estimated. RESULTS: The mean duration of illness of the sample was 18.8 years (SD 10.7) with >65% showing only small variation in positive and negative symptoms over a two to five-year time period. After adjustment for covariates, SSC showed to be negatively associated with positive symptoms after one year (ß = -0.47, p < 0.001, 95% CI = -0.70, -025) and two years (ß = -0.59, p < 0.001, 95% CI = -0.88, -0.30), and for negative symptoms after one year (ß = -0.52, p < 0.001, 95% CI = -0.77, -0.27). The prediction of negative symptoms was not significant at two years. CONCLUSION: This research indicates that interventions on SSC might positively impact mental health for people with psychosis. SSC is a small and robust predictor of future levels of positive symptoms. Negative symptoms could be predicted by SSC at one year.

RESUMEN

OBJECTIVES: The need for a brief screening tool for psychosis is widely recognized. The Community Assessment of Psychic Experiences (CAPE) is a popular self-report measure of psychosis, but a cut-off score that can detect those most likely to fulfill diagnostic criteria for psychotic disorder is not established. METHODS: A case-control sample from the Genetic Risk and Outcome of Psychosis Project study (N = 1375, healthy individuals, n = 507, and individuals with a psychotic disorder, n = 868), was used to examine cut-off scores of the CAPE with receiver operating curve analyses. We examined 27 possible cut-off scores computed from a combination of scores from the frequency and distress scales of the various factors of the CAPE. RESULTS: The weighted severity positive symptom dimension was most optimal in detecting individuals with a psychotic disorder (>1.75 cut-off; area under the curve = 0.88; sensitivity, 75%; specificity, 88%), which correctly identified 80% of the sample as cases or controls with a diagnostic odds ratio of 22.69. CONCLUSIONS: The CAPE can be used as a first screening tool to detect individuals who are likely to fulfill criteria for a psychotic disorder. The >1.75 cut-off of the weighted severity positive symptom dimension provides a better prediction than all alternatives tested so far.

RESUMEN

Introduction: In patients with psychotic disorders, both tobacco smoking and deficits in social cognition and social functioning are highly prevalent. However, little is known about their relationship in psychosis. The authors sought to evaluate the multi-cross-sectional and longitudinal associations between tobacco smoking, social cognition and social functioning in a large prospective study. Methods: This study was performed within the Genetic Risk and Outcome of Psychosis (GROUP) Study, a cohort study conducted in patients with non-affective psychosis (N = 1074), their unaffected siblings (N = 1047) and healthy controls (N = 549). At baseline, three years and six years of follow-up, data on tobacco smoking (using the Composite International Diagnostic Review), social cognition (emotion processing and theory of mind) and social functioning were collected. To assess associations between tobacco smoking and social cognition or social functioning, multivariate linear mixed-effects models and multiple linear regression models were used. Bonferroni correction for multiple testing was applied. Results: A significant positive association was found between smoking and emotion processing (as part of social cognition) in the patient group (estimate = 1.96, SE = 0.6, p = 0.003). However, smoking was significantly negatively associated with participating in pro-social activities compared with non-smoking (estimate = −2.55, SE = 0.9, p = 0.004). Change in smoking behaviour was not associated with social cognition or social functioning in the longitudinal analyses. Conclusion: Findings indicate that smoking patients with a non-affective psychotic disorder slightly outperformed their non-smoking peers on a task on social cognition, but participated less in pro-social activities. Commencement or cessation of smoking was not related to social cognition or functioning.

RESUMEN

Chronic mood disorders pose an important mental health problem. Individuals with these disorders experience a significant impairment, often fail to seek help, and their illnesses frequently do not respond to treatment. It is therefore important to develop innovative and attractive treatments for these disorders. Mindful yoga represents a promising treatment approach. This pilot study tested the feasibility of a 9-week manualized mindful yoga intervention for patients with chronic mood disorders. Eleven patients receiving standard treatment were recruited to complete a 9-week mindful yoga intervention. Qualitative methods were used to assess patients' experiences of the intervention and quantitative methods were used to assess psychological distress and mechanisms that play a role in chronic mood disorders. Eight patients completed the intervention and rated the overall quality of the intervention with a mean score of 8.8 (range of 8 to 9, using a scale of 1 to 10). All participants reported a reduction in psychological distress and no adverse events. Among the mechanisms that play a role in chronic mood disorders, the most potentially promising effects from the intervention were found for worry, fear of depression and anxiety, rumination, and areas related to body awareness, such as trusting bodily experiences and not distracting from sensations of discomfort. A 9-week mindful yoga intervention appears to be a feasible and attractive treatment when added to treatment as usual for a group of patients with chronic mood disorders. A randomized controlled trial to study the effects of mindful yoga is recommended.

RESUMEN

OBJECTIVE: Cognitive alterations putatively contribute to the risk for suicide in individuals with psychosis. Yet, a comprehensive assessment of social- and general-cognitive abilities in a large sample is lacking. METHODS: Seven-hundred-fifteen individuals diagnosed with a psychotic disorder performed tasks of facial emotion recognition, Theory of Mind, and general cognitive functioning (sustained attention, set-shifting, IQ-tests and verbal learning) as part of the Genetic-Risk-and-Outcome-of-Psychosis (GROUP) study. Presence of past suicide attempt/s and/or current suicidal ideation was reported by 261 individuals and 454 individuals reported no suicide attempt or ideation. We used general linear models to investigate group differences in task performance. All analysis were controlled for age, sex, education, and psychotic symptom severity. RESULTS: Individuals with suicide attempt and/or ideation showed better performance on the facial emotion recognition task and lower performance on tasks of sustained attention and verbal learning, compared to individuals without suicide attempt and/or ideation, without a clear effect of attempt or ideation. Theory of Mind performance was also better for individuals with suicide attempt and/or ideation, with largest differences between individuals who reported both attempts and ideation compared to individuals without suicide attempt and/or ideation. No effect of suicide attempt and/or ideation was found on misperception of facial emotions, IQ and set-shifting. Overall, effect sizes were small. CONCLUSION: Higher sensitivity to social-emotional cues together with weakened attentional control and learning capacity was observed in individuals with psychosis and suicide attempt and/or ideation. This may suggest that insufficient capacity for regulating perceived social stress contributes to suicidal thoughts and behavior.

RESUMEN

The burden of large and rare copy number genetic variants (CNVs) as well as certain specific CNVs increase the risk of developing schizophrenia. Several cognitive measures are purported schizophrenia endophenotypes and may represent an intermediate point between genetics and the illness. This paper investigates the influence of CNVs on cognition. We conducted a systematic review and meta-analysis of the literature exploring the effect of CNV burden on general intelligence. We included ten primary studies with a total of 18,847 participants and found no evidence of association. In a new psychosis family study, we investigated the effects of CNVs on specific cognitive abilities. We examined the burden of large and rare CNVs (>200 kb, <1% MAF) as well as known schizophrenia-associated CNVs in patients with psychotic disorders, their unaffected relatives and controls (N = 3428) from the Psychosis Endophenotypes International Consortium (PEIC). The carriers of specific schizophrenia-associated CNVs showed poorer performance than non-carriers in immediate (P = 0.0036) and delayed (P = 0.0115) verbal recall. We found suggestive evidence that carriers of schizophrenia-associated CNVs had poorer block design performance (P = 0.0307). We do not find any association between CNV burden and cognition. Our findings show that the known high-risk CNVs are not only associated with schizophrenia and other neurodevelopmental disorders, but are also a contributing factor to impairment in cognitive domains such as memory and perceptual reasoning, and act as intermediate biomarkers of disease risk.

RESUMEN

Objectives: There are a number of mindfulness-based programs (MBPs) that have demonstrated effectiveness for patients and health care professionals. The Interpersonal Mindfulness Program (IMP) is a relatively new MBP, developed to teach those with prior mindfulness training to deepen their mindful presence, empathy and compassion in the interpersonal domain. The aim of the present study was to examine the feasibility of using the IMP with mental health care workers and assessing its effects on levels of mindfulness, self-compassion, empathy, stress and professional quality of life when compared with the control group participants. Methods: The IMP training consisted of nine weekly 2.5-h sessions and daily home practice (45-60 min). Twenty-five participants (mean age, 51.4 years) with mindfulness experience participated in the training. Twenty-two individuals in the control group (mean age, 47.5 years) were recruited from those who had followed a mindfulness training before. Feasibility of the IMP was assessed in the training participants in six domains. All study participants completed self-report questionnaires before and after the training. Results: The IMP training was considered highly acceptable and very useful. The training had a significant positive effect on self-compassion, empathy and compassion fatigue, but no effect on mindfulness, stress and compassion satisfaction. Five participants reported some mild adverse reactions. Conclusions: The IMP training appears feasible for health care professionals and seems to induce some positive effects. A few mild adverse effects were reported. Further research on the effectiveness and possible mechanisms of change of the IMP training in larger samples is needed.

RESUMEN

INTRODUCTION: An updated summary of the most used instruments assessing auditory hallucinations in population with psychosis, allows us to underline the scarceness and need of Spanish versions of important instruments. The aim of the study is to examine the psychometric characteristics of two different and complementary instruments for assessing auditory hallucinations, the Spanish version of the Auditory Vocal Hallucination Scale (AVHRS) and the Spanish version of the Positive and Useful Voices Inquiry (PUVI). MATERIALS AND METHODS: A sample of 68 patients from four different centres, with a DSM-IV diagnosis of schizophrenia or schizoaffective disorder presenting with auditory hallucinations were included. Apart from the AVHRS and the PUVI, the Psychotic Symptom Rating Scales-Auditory Hallucinations subscale (PSYRATS-AH) and the Positive and Negative Syndrome Scale (PANSS) were also administered to all patients, plus an acceptability questionnaire. RESULTS: The Spanish version of the AVHRS showed a good internal consistency, a moderate to high inter-rater reliability, a medium to moderate test-retest reliability, and a good convergent and discriminant validity. The Spanish version of the PUVI showed a good internal consistency and a heterogeneous, but in general moderate, test-retest reliability. CONCLUSIONS: The Spanish versions of the AVHRS and the PUVI have good psychometric properties and are well accepted among patients.
