Background: Health literacy has received growing attention in recent years to reduce health disparities. Health literate individuals can gain access, understand and use health information to maintain, improve and promote good health. Objective: To develop and assess the psychometric properties of a tool for the measurement of health literacy among workers, the Health Literacy Scale for Workers (HELSW). Methods: 15 companies were selected from the factories of the industrial city of Saveh. 450 (400 male and 50 female) workers from Saveh, Iran, were selected through a multistage random sampling. The study had two stages—a qualitative and a quantitative stage. In the qualitative phase, the workers' beliefs were extracted based on 61 in-depth interviews. Content validity was assessed with the help of 12 experts in the field of health education, public health and occupational health. Also, face validity was evaluated through interviewing with 20 workers. In the quantitative phase, the reliability of the questionnaire was evaluated by measuring the internal consistency and test-retest reliability. The construct validity was assessed by the principal component analysis using varimax rotation. Results: In the exploratory factor analysis, six domains (ie, access, reading, understanding, assessment, decision making and applying health information, and self-efficacy) with 34 items were loaded; the model explained 64.3% of the total variance. Intraclass correlation coefficient and test-retest reliability ranged from 0.72 to 0.84 and 0.69 to 0.86, respectively. Conclusion: It seems that the developed Persian questionnaire, HELSW, is a reliable and valid measure of the health literacy in workers.

Abstract In empirical art psychology and creativity research most studies focus on the psychological correlates of art. Only few go beyond treating artworks as categorical data (e.g. abstract vs. representational) and consider artworks in detail. In part this is due to the lack of reliable quantitative measurements. The rating instrument for two-dimensional pictorial works (RizbA) makes a difference to current research designs. The current study validates the questionnaire on a representative sample of contemporary visual art, consisting of 318 images depicting works by artists from different cultural areas dated to the 21st century. In a randomized test-retest design, the pictorial material was rated by 506 (T1) and 238 (T2) art experts using RizbA. Statistical quality criteria, such as item difficulty, capacity of differentiation, test-retest reliability, and intraclass correlation were calculated. Principal component analysis (PCA) and indices of factor similarity were computed. The overall test’s capacity for differentiation yields partial eta-squared of .31 (T1) and .40 (T2). Test-retest reliability is .86. PCA reveals an eight-factor solution, which is largely consistent across both measurement points. Tucker’s coefficient of congruence ranges between |.71| and |1.00|. Intraclass correlation coefficients are .86 (T1) and .73 (T2). This study indicates generalizability of the questionnaire to contemporary artworks. Although a conclusion on the factors’ structure cannot be drawn yet, results are very promising. As the first reliable quantitative tool for formal picture analysis, RizbA allows more detailedexamination of visual art and its psychological correlates. This broadens research methodology by giving art greater weight in art psychology and creativity research.

The Impact

Following guidelines from the Patient-Centred Outcomes Research Institute and using a mixed methods study, a new patient-reported outcome measure (PROM) for both nerve trauma and compression affecting the hand, the Impact of a Hand Nerve Disorders (I-HaND) Scale, was developed. Face-to-face interviews with 14 patients and subsequent pilot-testing with 61 patients resulted in the development of the 32-item PROM. A longitudinal validation study with 82 patients assessed the psychometric properties of the I-HaND. Content and construct validity was confirmed by cognitive interviews with patients and through principal component analysis. The I-HaND has high internal consistency (α = 0.98) and excellent test–retest reliability (intraclass correlation coefficient = 0.97). Responsiveness statistics showed that the I-HaND can detect change over 3 months and discriminate between improvers and non-improvers. We conclude that the I-HaND can be used as a PROM for people with a range of hand nerve disorders.

AbstractBackground and aimsAssessing personality in research can be of importance, especially due to the potential relationship between different personality traits and the manifestation of symptoms in different clinical conditions. Therefore, it is important to have valid and reliable tools that allow for the assessment of personality traits. In this study, the aim was to translate and culturally adapt the Big Five Inventory (BFI) to the Danish language.MethodsA dual panel approach, consisting of a 4-person bilingual panel and an 8-person panel with laymen, was used to translate and culturally adapt the questionnaire. A third 9-person panel consisting of people with different medical diagnosis was used to assess the face validity. Internal consistency (Cronbach’s α) and test-retest reliability (intraclass correlation coefficients (ICC)) were tested amongst 96 subjects.ResultsThe translated version demonstrated adequate internal consistency (0.66–0.84) and good-excellent test-retest reliability (0.86–0.95). The smallest detectable change is between 1.13–1.70 for the five subscales. Both the healthy and patient panels of laymen considered the questionnaire too long.ConclusionThis translated version of the Big Five Inventory demonstrated high to very high test-retest reliability and, for most parts, an acceptable internal consistency. The construct validity was however different from versions translated into languages geographically and culturally similar to Danish.ImplicationsAssessing the Big Five personality traits in Danish populations can be valuable for many reasons, e.g. when assessing people in pain in both clinical and experimental settings. Improved knowledge of the underlying driver of pain conditions is important. Here, understanding how personality may interact with pain can help researchers and clinicians.

Objective: The development of instruments to measure emotional maladjustment in diabetic Hispanic populations has received little attention. We present the development and validation of the Diabetes Emotional Adjustment Scale in Spanish. Method: An eighteen-item self-administered scale was construed to assess emotional adjustment in Spanish-speaking diabetic patients and the psychometric properties of the scale were assessed. The scale was applied to a sample of sixty patients and scale scores were correlated with scores on a battery of Spanish versions of established measures of psychological distress, to assess concurrent validity. Test-retest reliability was established four years later re-examining thirty-eight of the initial sixty-patients sample. Results: Split-half reliability and test-retest reliability were satisfactory. There were significant correlations between the scale results and measures of depression, trait-anxiety, family adjustment, and locus of control of behavior. A principal component analysis with varimax rotation yielded a six-factor solution explaining 50.4 percent of the total variance. Conclusions: The scale is useful as a screening instrument, but the confirmation of factor structure stability and the correlation of the scale results with objective measures of metabolic control, require further investigation.

ObjectiveThis study describes the development and validation of the Menstrual Practice Needs Scale (MPNS-36), which measures the extent to which respondents’ menstrual practices and environments meet their needs.MethodsA 54-item pool was developed following systematic review of qualitative and quantitative studies and expert feedback. Item reduction and scale validation were undertaken using a cross-sectional survey of 538 menstruating schoolgirls in Soroti, Uganda. Test–retest reliability was assessed in a subsample of 52 girls 2 weeks after the first administration. Construct validity was tested through relationships with hypothesised correlates: confidence to manage menses, self-reported school absenteeism and mental health symptoms.ResultsThe MPNS-36 comprises 28 items applicable to all respondents and 8 items capturing washing and drying experiences for those reusing menstrual materials. A four-factor solution for the core 28 items was the best fit for the data (root mean square error of approximation (RMSEA)=0.028–0.029; comparative fit index (CFI)=0.961–0.964; Tucker-Lewis index (TLI)=0.953–0.955), supplemented by two factors for reuse (RMSEA=0.021–0.030; CFI=0.987–0.994; TLI=0.981–0.991). Subscale and total scores were calculated as mean scores to support accessibility for practitioners. The subscales were ‘material and home environment needs’ (11 items, αordinal=0.84), ‘transport and school environment needs’ (5 items, αordinal=0.73), ‘material reliability concerns’ (3 items, αordinal=0.55), ‘change and disposal insecurity’ (9 items, αordinal=0.80), ‘reuse needs’ (5 items, αordinal=0.76) and ‘reuse insecurity’ (3 items, αordinal=0.56). Relationships between subscales and hypothesised correlates supported validity. Home-based and school-based items were more strongly associated with confidence to manage menstruation at home and school, respectively. Higher total scores indicated more positive experiences and were associated with greater odds of not missing school during the last menstrual period (OR=2.62, 95% CI 1.52 to 4.50). Test–retest reliability was moderate (total score: intraclass correlation coefficient, ICC(2,1)=0.69).ConclusionsThe MPNS-36 demonstrated acceptable reliability and validity. It is the first measure to capture perceived menstrual hygiene and may be useful across a range of study designs. Future research should explore the validity and suitability of the measure across contexts and populations.

AbstractIn this study, the test-retest-reliability as one aspect of reliability of metamorphopsia measurements using a computer-based measuring method was determined in patients with macular diseases. Metamorphopsia amplitude, position, and area were quantified using AMD – A Metamorphopsia Detector software (app4eyes GmbH & Co. KG, Germany) in patients with diabetic, myopic, or uveitic macular edema, intermediate or neovascular age-associated macular degeneration, epiretinal membrane, vitelliform maculopathy, Irvine-Gass syndrome, or macular edema due to venous retinal occlusion. The intraclass correlation coefficient (ICC) was calculated in order to determine the repeatability of two repeated measurements and was used as an indicator of the reliability of the measurements. In this study, metamorphopsia measurements were conducted on 36 eyes with macular diseases. Metamorphopsia measurements made using AMD – A Metamorphopsia Detector software were highly reliable and repeatable in patients with maculopathies. The intraclass correlation coefficient of all indices was excellent (0.95 – 0.97). For diseases of the vitreoretinal interface or macular diseases with intra- or subretinal edema, this metamorphopsia measurement represents a supplement for visual function testing in the clinic, as well as in clinical studies.

Abstract Background Health literacy refers to the ability of individuals to gain access to, use, and understand health information and services in order to maintain a good health. It is especially important in nephrology due to the complexity of chronic kidney disease (CKD). The present study sought to define health literacy levels in patients followed in predialysis clinic, in-center dialysis (ICHD), peritoneal dialysis (PD) and home hemodialysis (HHD). Methods This transversal monocentric observational study analysed 363 patients between October 2016 and April 2017. The Brief Health Literacy Screen (BHLS) and the Health Literacy Questionnaire (HLQ) were used to measure health literacy. Multivariate linear regressions were used to compare the mean scores on the BHLS and HLQ, across the four groups. Results Patients on PD had a significantly higher BHLS’score than patients on ICHD (p = 0.04). HLQ’s scores differed across the groups: patients on HHD (p = 0.01) and PD (p = 0.002) were more likely to feel understood by their healthcare providers. Compared to ICHD, patients on HHD were more likely to have sufficient information to manage their health (p = 0.02), and patients in the predialysis clinic were more likely to report high abilities for health information appraisal (p < 0.001). Conclusion In a monocentric study, there is a significant proportion of CKD patients, especially in predialysis clinic and in-centre hemodialysis, with limited health literacy. Patients on home dialysis (HHD and PD) had a higher level of health literacy compared to the other groups.

Abstract Background To evaluate the psychometric and measurement properties of two patient-reported outcome instruments, the menstrual pictogram superabsorbent polymer-containing version 3 (MP SAP-c v3) and Uterine Fibroid Daily Bleeding Diary (UF-DBD). Test-retest reliability, criterion, construct validity, responsiveness, missingness and comparability of the MP SAP-c v3 and UF-DBD versus the alkaline hematin (AH) method and a patient global impression of severity (PGI-S) were analyzed in post hoc trial analyses. Results Analyses were based on data from up to 756 patients. The full range of MP SAP-c v3 and UF-DBD response options were used, with score distributions reflecting the cyclic character of the disease. Test-retest reliability of MP SAP-c v3 and UF-DBD scores was supported by acceptable intraclass correlation coefficients when stability was defined by the AH method and Patient Global Impression of Severity (PGI-S) scores (0.80–0.96 and 0.42–0.94, respectively). MP SAP-c v3 and UF-DBD scores demonstrated strong and moderate-to-strong correlations with menstrual blood loss assessed by the AH method. Scores increased in monotonic fashion, with greater disease severities, defined by the AH method and PGI-S scores; differences between groups were mostly statistically significant (P < 0.05). MP SAP-c v3 and UF-DBD were sensitive to changes in disease severity, defined by the AH method and PGI-S. MP SAP-c v3 and UF-DBD showed a lower frequency of missing patient data versus the AH method, and good agreement with the AH method. Conclusions This evidence supports the use of the MP SAP-c v3 and UF-DBD to assess clinical efficacy endpoints in UF phase III studies replacing the AH method.

Abstract Objective The aim of this study was to translate to Spanish the patellofemoral pain and osteoarthritis subscale of the knee injury and osteoarthritis outcome score (KOOS-PF) and validate this Spanish version of a disease-specific patient-reported outcome measure (PROM) for patellofemoral pain. Results The KOOS-PF was translated to Spanish and sixty patients with patellofemoral pain and/or osteoarthritis accepted to complete the questionnaire. 1-week later 58 patients answered the questions again for the test–retest reliability validation and finally 55 patients completed 1-month later for the responsiveness assessment. The Spanish version showed very good internal consistency (Cronbach’s alpha: 0.93) and test–retest reliability (intraclass correlation coefficient: 0.82). Responsiveness was confirmed, showing a strong correlation with the global rating of change (GROC) score (r 0.64). The minimal detectable change was 11.1 points, the minimal important change was 17.2 points, and there were no floor or ceiling effects for the score.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P &lt; 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.
