Validation of the Sense of Community Coherence Scale for German and Turkish cultures.

Sense of community coherence refers to how much a person perceives their communal life as comprehensible, manageable and meaningful. The study's purpose was to validate the Sense of Community Coherence Scale using two distinct groups of university students from Germany and Turkey. The scale was adapted to German and Turkish using the translation-back translation method and examined in terms of several indicators of reliability and validity, including cross-cultural measurement invariance with the data collected from 489 individuals from Germany and 533 individuals from Turkey. The findings exhibited satisfactory psychometric properties; specifically, high reliability, good construct and criterion validity, and partial measurement invariance across cultures were observed. As a result, Sense of Community Coherence Scale was concluded to be reliable and partially valid in the samples of Turkish and German university students. Validation of the German and Turkish forms of the scale is expected to contribute to mental health research and practice for allowing the measurement of how individuals feel about their community in the context of manageability, meaningfulness and comprehensibility. This study can help researchers and practitioners design enhancement, prevention and intervention programmes aiming to increase the community sense of coherence.

Arabic validation of the Body-Esteem Scale for Adolescents and Adults

ObjectivesThe aim of this study was to validate the questionnaire “Body-Esteem Scale for Adolescents and Adults” (BESAA). MethodsWe conducted a cross-sectional study involving 340 adolescents who attend a Tunisian high school. We translated the BESAA into dialectal Tunisian Arabic based on the translation back-translation method. The validity of the scale was evaluated through content validity, reliability and construct validity. We used the Arabic version of the Rosenberg Self-Esteem Scale as an external validator. The cut-off of the scale was calculated using the ROC curve. ResultsThe translated version was considered satisfactory. The exploratory analysis related three factors similar to the original version of the questionnaire. We dropped eight items (1, 4, 6, 14, 15, 18, 19 and 23) and obtained a 15-item version. A principal component analysis was carried out of the new version and produced a three-component solution that accounted for 64.56% of the total BESAA variance. In confirmatory analysis, the scale demonstrated good model fit statistics as follows: Comparative Fit Index=0.92; Goodness of Fit Index=0.89; Adjusted Goodness of Fit Index=0.85; Root Mean Square Error of Approximation=0.13 and Standardized Root Mean Square Residual=0.09. The internal consistency showed a good result with a Cronbach's alpha of 0.753. The correlation between items and subscales demonstrated statistically significant and logical results. Statistically significant correlations were found between the BESAA and its external validator the Rosenberg Self-Esteem Scale (r=0.382; P<0.01). The cut-off of our scale was equal to 24.5. ConclusionsThe Tunisian 15-item version of the BESAA is a psychometrically valid measure. This scale can be reliably used to conduct further studies and research on body esteem in the Tunisian population.

Validation of the Sinhala version of the Autism Treatment Evaluation Checklist (ATEC)

Background: Autism Spectrum Disorder is a neuro developmental disorder which has a trend in its increasing prevalence globally. Measuring the outcome of intervention will have a great value for parents and clinicians. At present, there are no tools validated in the Sri Lankan setting to assess treatment outcomes in Autism Spectrum Disorder. Autism Treatment Evaluation Checklist (ATEC) is a self-administered questionnaire in Sinhala for parents/caregivers that is a feasible method of evaluating outcome in a busy clinic.Aims: This study was conducted to translate and culturally adapt the ATEC to the Sinhala language and to establish the validity and reliability of the translation to the local setting.Methods: Permission was sought from the developers of the ATEC questionnaire and ethical approval was obtained for the study. Study was conducted in two stages. In the first stage, ATEC was translated using the translation-back translation method. An expert panel produced a pre-final questionnaire which was pre-tested prior to formulating the final Sinhala version of ATEC. The second stage of the study was conducted to establish validity and reliability of Sinhala ATEC questionnaire in the Sri Lankan popu-lation. Content validity was assured in each step of the translation by the expert committee. Construct validity of the Sinhala ATEC questionnaire was assessed by comparing the sample of 119 parent/caregiver filled final version of the Sinhala ATEC score against the Consultant Child and Adolescent Psychiatrist assessment of the same children conducted independently and recorded according to DSM-5 (level 1, 2 or 3). Test-retest reliability was determined by the same parent/caregiver filling the Sinhala ATEC one week later, in a sample of 14 children. Intra-rater reliability was taken by com-paring 18 pairs of parents/caregivers Sinhala ATEC scores for the same child.Results: Sinhala ATEC showed high validity and reliability. Its concurrent validity has a strong positive Pearson correlation of 0.856 with the Consultant Psychiatrist assessment. Correlation was higher in total score and as well as in subscale II- Sociability score of the Sinhala ATEC. Internal consistency was revealed by Cronbach’s alpha 0.778. Cut off points to distinguish mild autism spectrum disorder from the rest taken as “48 or less” with sensitivity 82%, specificity 94% and area under the curve 0.968. Cut off to separate severe autism spectrum disorder from the rest were taken as “76 or more” with sensitivity 84%, specificity 90%and area under the curve 0.971. Reliability tests, intra class correlation was 0.98 and 0.96 for test-retest and intra rater reliability showed high reliability of Sinhala ATEC. For developing burnout in this study population.Conclusions: Translated version of Sinhala ATEC is suitable for the use in the Sri Lankan population as it shows high validity and reliability. However, further studies are recommended in other areas of the country to assess its usefulness across diverse subcultures and clinical settings.

Validation de la version Tunisienne du Pittsburgh Sleep Quality Index auprès d’une population d’adolescents

Sleep quality is a complex phenomenon with quantitative and subjective aspects that vary during adolescence. The prevalence of sleep disorders is not known in Tunisia due to the lack of validated tools. To translate and validate the questionnaire Pittsburgh Sleep Quality Index (PSQI) into Tunisian Arabic in middle school students. We translated the PSQI into Tunisian Arabic based on the translation back-translation method. We conducted a cross-sectional study on a sample of 560 adolescents. Exploratory factor analysis was performed to study construct validity. To test reliability, the global internal consistency of the scale was computed. The construct validity was verified by factor analysis, proving that a single factor explained 30.3% of the overall variance. This model produced a good factor load for all the components. The analysis of the reliability showed an acceptable internal consistency (Cronbach's alpha=0.6). The Arabic Tunisian version of the PSQI is a psychometrically valid measure. The PSQI could be useful for the detection and evaluation of symptoms of sleep disorders, as well as for further studies and researches about associated factors with poor sleep quality in adolescent and youth.

Turkish validity and reliability of the Premenstrual Change Coping Inventory.

This study was conducted to investigate the validity and reliability of the Turkish version of the Premenstrual Change Coping Inventory (PMS-Cope). A total of 170 women who met the inclusion criteria were included in the methodological study. Data were collected between the dates of November 5, 2018 and May 5, 2019 with personal information form, PMS-Cope Turkish version, and Premenstrual Syndrome Scale. The PMS-Cope was obtained through the translation-back translation method and the content validity was obtained according to expert opinions. After the factor analysis, the Turkish version of the PMS-Cope consisted of three sub-dimensions as in the original scale. The factor loadings of the three-dimensional scale ranged from 0.46 to 0.84, and the explained variance (60.329%) was at the desired level. As a result of structural equation modeling; ×2/SD values of the scale were found to be 4.19, GFI 0.93, AGFI 0.91, CFI 0.95, RMSEA 0.079, and SRMR 0.082, and this scale was acceptable. The Cronbach alpha coefficient of the PMS-Cope was 0.86. It was determined that item-total score correlations were higher than 0.30 in all items of PMS-Cope and there was no need to remove items from the scale. When the mean scores of the lower 27% and upper 27% of the scale were compared, a statistically significant difference was found between the groups (p < 0.05). The PMS-Cope score was 41.04 ± 8.99. It was determined that the Turkish version of the PMS-Cope was a valid and reliable measurement tool.

Validity and Reliability of the Korean Versions of the 9- and 19-Item Wearing-Off Questionnaires in Parkinson's Disease.

The wearing-off (WO) phenomenon is the most common motor complication in advanced Parkinson's disease (PD), but its identification remains challenging. The 9- and 19-item Wearing-off Questionnaires (WOQ-9 and WOQ-19) are self-assessment tools for motor and nonmotor symptoms that are widely used for WO screening. We produced Korean versions of the WOQ-19 and WOQ-9 (K-WOQ-19 and K-WOQ-9) and investigated their validity and reliability. We used the translation-back translation method to produce K-WOQ-19 and K-WOQ-9, which were self-administered by 124 patients with PD. We conducted in-depth 10-minute interviews for confirming the presence of the WO phenomenon, and then stratified the participants into groups with and without WO. Diagnostic accuracy was assessed byanalyzing receiver operating characteristic curves. Concurrent validity was assessed using the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) andthe Hoehn and Yahr stage with Spearman's rank correlation analysis. Reliability was assessedbased on test-retest Cohen's kappa (κ) values and intraclass correlation coefficients (ICCs). The optimal cutoff scores on the K-WOQ-19 and K-WOQ-9 for WO screening were 4 and 2, respectively. The test-retest ICCs of K-WOQ-19 and K-WOQ-9 were 0.943 and 0.938, respectively. Nineteen of the combined 20 items in K-WOQ-19 and K-WOQ-9 showed moderate-to-substantial agreement (κ=0.412-0.771, p<0.001). The scores on the translated scales were significantly correlated with MDS-UPDRS IV scores. K-WOQ-19 and K-WOQ-9 are reliable and valid tools for detecting WO, with optimal cutoff scores of 4 and 2, respectively.

Kalp Cerrahisi Semptom Envanterinin Türk Dilinde Geçerlik ve Güvenirliği

This study was conducted to evaluate the validity and reliability of the Heart Surgery Symptom Inventory (HSSI) in Turkish language. This methodological study consisted of 312 patients who had CABG surgery in a public and a foundation university hospital between December 2017 and September 2018. Data were collected with the Patient Information Form and the HSSI. Language validity of the HSSI was analyzed by the translation-back translation method. Content validity was evaluated by Davis technique. Cronbach α coefficient, and item total correlation were examined for the reliability of the inventory. Kaiser-Mayer-Olkin (KMO) and Bartlett's tests were performed to evaluate the sampling adequacy and the suitability of the data for factor analysis. KMO value was 0.867, which indicates suitability for principal component analysis. Bartlett's test was found as x2=22733.809; p=0.000 and this value shows that the data are related to each other and are suitable for factor analysis. Content Validity Index (CVI) of the inventory was found 0.84. Factor loadings of the 35-item HSSI, which was examined as a single sub-dimension, varied between 333 and 858, and explained variance was 44.922%. The total Cronbach alpha coefficient was 0.961 and the total item correlations for all items were positive. As a result, the HSSI with single-subscale and 35-item was found to be valid and reliable inventory in Turkish language and could be used for the evaluation of symptoms after heart surgery.

Translation and cultural adaptation of MedStopper®-A web-based decision aid for deprescribing in older adults: A protocol.

Older patients are more likely to have medication-related problems, which are associated with changes in pharmacokinetics and pharmacodynamics, multimorbidity, and polypharmacy. Polypharmacy and inappropriate prescribing are well-known risk factors which commonly cause adverse clinical outcomes in older people. Prescribers struggle to identify potentially inappropriate medications and to choose an adequate tapering approach. The goal of the study is to translate and culturally adapt MedStopper®, an original English language web-based decision aid system in deprescribing medication, to the Portuguese population. A translation-back translation method, with validation of the obtained Portuguese version of MedStopper® will be used, followed by a comprehension test. This is the first research in the Portuguese primary care setting that aims to provide a useful online tool for the appropriate prescription of older patients. The translated version in Portuguese version of the MedStopper® tool will represent an advance that seeks to continue improving the management of medications in the elderly. The adaptation into Portuguese of the educational tool provides clinicians with a screening tool to detect potentially inappropriate prescribing in patients older than 65 that reliable and easier to use. Retrospectively registered.

Inclusion of Spanish-Speaking Families in NICU Symptom Research Using a Community Advisory Board.

Admission rates of Hispanic/Latinx families to the neonatal intensive care unit (NICU) are rising, yet knowledge regarding their experiences is limited. Non-English-speaking families are often excluded from research because study measures are not available in their language. The inclusion of these families in NICU research is crucial to understand the impact of cultural and language barriers in infant and family care, and the translation of study measures into Spanish could better ensure that these families' perspectives are included. However, previous research has utilized the standard translation-backtranslation method with which problems have been noted. This article describes the planning, preparation, and action phases that were completed with the use of a community advisory board (CAB) to prepare and transcreate research study materials from English to Spanish for pilot testing. Community members of interest were invited to form the CAB, and 2 meetings were held to review study materials in the English and Spanish versions. Prior to the second meeting, a professional translation company translated study materials from English to Spanish. Feedback from the CAB ensured consistent content and reading levels, and culturally appropriate language usage. The CAB also provided suggestions to the research protocol and advised sensitive methods of recruitment and measure administration. More accurate and culturally appropriate transcreation of study measures can reduce barriers to research participation and facilitate better communication with non-English-speaking families in health equity research to better inform evidence-based interventions and clinical practices across diverse groups.

Sporda Gözlemsel Kolektif Yeterlik Ölçeği: Türkçe Formunun Geçerlik ve GÜvenirlik Çalışması

The study aimed to analyze the Observational Collective Efficacy Scale for Sport (OCESS). 242 Turkish athletes and 85 Turkish coaches participated in the study. After performing the first step for the language validity of the scale by using the translation-back translation method, it was sent to the athletes as an online form. Athletes responded to the items voluntarily. KMO and Bartlett’s test of sphericity values were calculated to determine whether the data was proper for factor analysis. The initial factor structure of the scale was tested with CFA. While the Pearson correlation test was used for criterion-related validity, the internal consistency coefficient was calculated with Cronbach’s alpha. While KMO was found to be 0.84, Bartlett’s test of sphericity was statistically significant. The item factor loadings ranged between 0.64 and 0.88. In sum, the Turkish version of the OCESS presents acceptable psychometric properties and may be used to assess athletes’ collective efficacy beliefs in team sports repeatedly.

Eating Disorder-15: Factor Structure, Psychometric Properties, Validity, and Reliability of the Turkish Version for Clinical and Non-Clinical Samples.

Eating Disorder-15 (ED-15) is a self-report scale recommended for use to evaluate weekly progress and treatment results in eating disorders. This research aims to examine the factor structure, psychometric properties, validity, and reliability of the Turkish version of ED-15 (ED-15-TR) for clinical and non-clinical samples. Translation-back translation method was used for language equivalence of ED-15-TR. The research was conducted with a total of 1049 volunteers, with two sample groups as non-clinical (n=978) and clinical (n=71). The participants completed an information form, ED-15-TR, Eating Disorder Examination Scale (EDE-Q), and Beck Depression Inventory (BDI). Three hundred fifty-two participants from the non-clinical group and 18 from the clinical group completed ED-15-TR again within a week. Factor analysis confirmed the two-factor structure of ED-15- TR. Cronbach's alpha value was 0.911 (0.773, and 0.904 for the two subscales respectively), the intraclass correlation coefficient for testretest reliability was 0.943 in the clinical group (0.906, and 0.942 for the two subscales respectively); 0.777 (0.699, and 0.776 for the two subscales respectively) in the non-clinical group (for all p<0.001). The high level of a positive correlation between ED-15-TR and EDE-Q supported concurrent validity. This research indicates that ED-15-TR is an acceptable, valid, and reliable self-report scale for Turkish society.

Validation of the severe respiratory insufficiency questionnaire for Chile

BackgroundLong-term home non-invasive ventilation (LTH-NIV) has an impact on the health-related quality of life of patients with chronic hypercapnic respiratory failure (CRF) of different causes. There are generic and specific questionnaires for respiratory diseases. In 2003 a specific questionnaire was developed for patients with CRF in LTH-NIV, called the Severe Respiratory Insufficiency (SRI) questionnaire, which has been shown to be reproducible and reliable and has been validated in several languages.The aim of the study was to translate and culturally adapt the SRI questionnaire for adult Chilean patients under LTH-NIV, and to assess its psychometric properties.MethodsThe Chilean version of the SRI was obtained using the translation-back translation method, which was then applied by cross-sectional study to a non-probabilistic convenience sample of stable patients from five regions of Chile. The validated Chilean version of the SRI questionnaire and SF-36 (gold standard) questionnaire were applied, demographic and ventilatory data were collected. Reliability was analysed using Cronbach’s alpha and intraclass correlation (test–retest). Construct validity was tested using exploratory factor analysis (principal component extraction and equimax orthogonal rotation) and hypothesis testing (Mann–Whitney test). Convergent criterion validity was tested using Spearman’s rho.ResultsThe sample comprised 248 patients, 132 women (53.2%), median age (IQR) was 62 years (51–75), 146 patients (58.9%) were 60 years or older, 40% had a low education level. The mean ± SD completion time of the questionnaire was 18.8 ± 9.1 min, and 100% of the items were answered. The questionnaire was self-applied by 46.8% of the sample. The validated Chilean version of the SRI questionnaire showed very good overall reliability (0.95) and by scales (> 0.7). It showed a good correlation with the SF-36, with equivalent scales, a rotated matrix with 8 factors and hypotheses that explain the underlying constructs.ConclusionsThe validated Chilean version of the SRI questionnaire has good psychometric properties. It is feasible, valid, and reliable for application to evaluate patients with CRF in LTH-NIV. It was found to be sensitive to assess the characteristics of the local population.

Turkish validity and reliability of the postpartum stressors scale

ABSTRACT This study was conducted to examine the validity and reliability of the Postpartum Stressor Scale (PPSS) in Turkish.177 women were included in the methodological study. The data were collected between 24 September 2018 and 24 January 2019. The validity and validity of PPSS according to the language validity and expert opinions was provided by the translation-back translation method. It was determined that the Turkish form of the PPSS did not occur in three sub-dimensions such as the original structure. Therefore, the factor loadings of the PPSS one-dimensional scale ranged from 0.481 to 0.678, and the explained variance (35.3%) was sufficient. According to the results of CFA, factor loadings of the model ranged from 0.40 to 0.64, and t values of all substances were above 1.96. As a result of structural equation modeling. The obtained fit index values of the scale were found to be x2/SD 1.88, GFI 0.93, AGFI 0.88, CFI 0.95, RMSEA 0.071 and SRMR 0.065, and the model was acceptable. The Cronbach’s alpha reliability coefficient of PPSS was 0.76. In all items of PPSS, item total score correlations were found to be over 0.30 and there was no need to exclude item from the scale. PPSS was determined as a reliable and valid tool for Turkish society. There was a positive significant correlation between PPSS and PSS (p = 0.000). When the mean scores of lower 27% and upper 27% were compared, statistically significant difference was found between the groups (p = 0.000). The mean score of PPSS was 16.67 ± 5.74. As a result of the study, it was determined that the Turkish version of PPSS was a valid and reliable measurement tool.

Inappropriate Prescriptions in Older People-Translation and Adaptation to Portuguese of the STOPP/START Screening Tool.

Inappropriate prescribing, which encompasses the prescription of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs), is a common problem for older people. The STOPP/START tool enables general practitioners, who are the main prescribers, to identify and reduce the incidence of PIMs and PPOs and appraise an older patient’s prescribed drugs during the diagnosis process to improve the clinical care quality. This study aimed to translate and validate the STOPP/START screening tool to enable its use by Portuguese physicians. A translation-back translation method including the validation of the obtained Portuguese version was used. Intra- and inter-rater reliability and agreement analyses were used in the validation process. A dataset containing the information of 334 patients was analyzed by one GP twice within a 2-week interval, while a dataset containing the information of 205 patients was independently analyzed by three GPs. Intra-rater reliability assessment led to a Kappa coefficient (κ) of 0.70 (0.65–0.74) for the STOPP criteria and 0.60 (0.52–0.68) for the START criteria, considered to be substantial and moderate values, respectively. The results of the inter-rater reliability rating were almost perfect for all combinations of raters (κ > 0.93). The version of the STOPP/START criteria translated into Portuguese represents an improvement in managing the medications prescribed to the elderly. It provides clinicians with a screening tool for detecting potentially inappropriate prescribing in patients older than 65 years old that is reliable and easy to use.

Reliability and validity of the Turkish version of Post-COVID-19 Functional Status Scale

Background/aimThe post-COVID-19 Functional Status (PCFS) has recently been developed for functional outcomes of COVID-19 upon discharge and in long term. The purpose of this study was to investigate the reliability and validity properties of the Turkish version of the PCFS in Turkish post-COVID-19 patients with hospitalized and nonhospitalized during infection.Materials and methods One hundred participants with post-COVID-19 were included in this cross-sectional study. Test-retest reliability of the Turkish version of PCFS assessed by intraclass correlation coefficient (ICC) and Cronbach’s alpha was calculated for internal consistency. For construct validity, correlation coefficients between the Turkish version of PCFS developed by translation-back translation method and modified Medical Research Council (mMRC) dyspnea scale (MMRC), London Chest Activities of Daily Living (LCADL) scale, Barthel Index (BI) were analyzed.Results For test-retest reliability analysis, ICC ranged between 0.734 and 0.880. The total ICC score was 0.821, indicating excellent reliability. The Cronbach’s alpha value of the PCFS test and retest scores were recorded as 0.821 indicating that the scale is quite reliable. The PCFS score was moderately correlated with the mMRC score (r = 0.534, p < 0.001) and weakly correlated with the LCADL self care (r = 0.311, p = 0.002), domestic (r = 0.277, p = 0.005), physical activity (r = 0.342, p < 0.001), leisure subscores (r = 0.434, p < 0.001) and total score (r = 0.399, p < 0.001).Conclusion The Turkish version of the PCFS scale is reliable scale that reflects activity limitation and functional status after COVID-19. The Turkish version of the PCFS will be a guide for rehabilitation professionals to understand functional limitation after COVID-19 and to direct interventions accordingly to functional status of the patients at discharge and in long term.

Validity and reliability of the Turkish version of Sleep Disturbance Scale for Children

ObjectThis study examines the validity and reliability of the Sleep Disturbance Scale for Children (SDSC) in the Turkish language. MethodThis scale was translated into the Turkish language by applying the translation-back translation method and content validity analysis. A total of 1903 participants aged 5–15 years were included in the study. A sociodemographic data form, SDSC, and the Children's Sleep Habits Questionnaire (CSHQ) were filled by the parents. Internal consistency analysis, correlation analysis, test-retest analysis, and confirmatory factor analysis were applied to evaluate the reliability and validity of the applied scale. ResultsThe internal consistency of the scale was high (Cronbach α = 0.84). Test-retest reliability was found to be high as well. According to the confirmatory factor analysis, the Turkish version of the scale was compatible with the model of the original scale. According to the T-score evaluation, the frequency of sleep disorders was determined to be 4.15%, and the most common sleep disorder was sleep hyperhidrosis. Correlations between the scores of the SDSC and CSHQ were at a satisfactory level. ConclusionsThese results revealed that the SDSC is a valid and reliable scale that can be used in children aged 5–14 years in Turkey to question sleep disorder symptoms.

POS1462-HPR VALIDITY AND PSYCHOMETRIC CHARACTERISTICS OF THE PSORIATIC ARTHRITIS QUALITY OF LIFE (PSAQOL) QUESTIONNAIRE IN TURKISH POPULATION

Background:Psoriatic Arthritis Quality of Life (PsAQoL) questionnaire was developed to measure quality of life (QoL) in patients with psoriatic arthritis (PsA) (1).Objectives:The aim of the study was to assess validity and psychometric properties of the PsAQoL questionnaire.Methods:The translation-back translation method by a bilingual panel was used to translate the original PsAQoL into Turkish (2). Face and content validities were evaluated via cognitive debriefing interviews with 10 PsA patients. Then, patients with PsA according to CASPAR criteria were recruited to assess feasibility, missing data, floor and ceiling effect, reliability, and construct validity. Reliability was assessed by internal consistency. Construct validity was investigated by convergent and divergent validity by assessing the PsAQoL’s relations with QoL and non-QoL parameters. For this purpose, demographics, clinical characteristics (shown in Table 1), survey data including PsAQoL, Short form 36, visual analog scales for pain and fatigue, Health Assessment Questionnaire, and Hospital Anxiety and Depression Scale results were recorded.Results:One hundred and sixty-two patients were recruited and 74 of them had axial PsA. Cognitive debriefing showed the Turkish version of PsAQoL to be clear, understandable, and relevant. It was easy to complete and calculate, with the 3 minutes and 20 seconds, respectively. The Cronbach’s alpha coefficient for internal consistency was 0.930. The questionnaire presented no floor or ceiling effect (&lt;15% for both) and no missing data. PsAQoL showed good correlations with the QoL scales indicating its convergent validity and moderate to non-significant correlations with the non-QoL parameters supporting its divergent validity (Table 1).Conclusion:The Turkish version of the PsAQoL is a valid and disease-specific instrument with good psychometric characteristics to assess PsA-specific QoL.
