PURPOSE: To contribute to the development of a Brazilian Portuguese language version of the vocal self-assessment questionnaire, Transsexual Voice Questionnaire: Male-to-Female (TVQ:MtF), and to evaluate the questionnaire for use in Brazil. METHODS: The research was divided into two parts: (1) translation and adaptation of the questionnaire (TVQ:MtF) and demographic form and (2) preliminary study of the psychometric properties (internal consistency and test-retest reliability) of the adapted version of the questionnaire. For the translation and adaptation, the following steps were taken: translation, reconciliation, back-translation, harmonization, and pilot test. The TVQ:MtF questionnaire and the demographic form were applied to 13 male-to-female transsexuals, aged between 21 and 47 years. The participants agreed to answer the TVQ:MtF on two occasions (test and retest), with an optimal interval of 30 days. RESULTS: Two psychometric properties were investigated: internal consistency and test-retest reliability. High levels of internal consistency (in both test (α=0.911) and retest (α=0.952) conditions) and reliability (with an average ICC=0.957 (95%CI 0.916-0.984)), were found. CONCLUSION: The TVQ:MtF is an appropriate instrument for vocal self-assessment of male-to-female transsexual patients, which can be recommended for clinical and research goals.

ABSTRACTBackground:The Geriatric Anxiety Inventory (GAI) is a recently developed scale aiming to evaluate symptoms of anxiety in later life. This 20-item scale uses dichotomous answers highlighting non-somatic anxiety complaints of elderly people. The present study aimed to evaluate the psychometric properties of the Brazilian Portuguese version GAI (GAI-BR) in a sample from community and outpatient psychogeriatric clinic.Methods:A mixed convenience sample of 72 subjects was recruited for answering the research protocol. The interview procedures were structured with questionnaires about sociodemographic data, clinical health status, anxiety, and depression previously validated instruments, Mini-Mental State Examination, Mini International Neuropsychiatric Interview, and GAI-BR. Twenty-two percent of the sample were interviewed twice for test–retest reliability. For internal consistency analyses, the Cronbach's α test was applied. The Spearman correlation test was applied to evaluate the test–retest GAI-BR reliability. A ROC (receiver operating characteristic) curve study was made to estimate the GAI-BR area under curve, cut-off points, sensitivity, and specificity for the Generalized Anxiety Disorder diagnosis.Results:The GAI-BR version showed high internal consistency (Cronbach's α = 0.91) and strong and significant test–retest reliability (ρ = 0.85, p < 0.001). It also showed moderate and significant correlation with the Beck Anxiety Inventory (ρ = 0.68, p < 0.001) and the State-Trait Anxiety Inventory (ρ = 0.61, p < 0.001) showing evidence of concurrent validation. The cut-off point of 13 estimated by ROC curve analyses showed sensitivity of 83.3% and specificity of 84.6% to detect Generalized Anxiety Disorder (DSM-IV).Conclusion:GAI-BR has demonstrated very good psychometric properties and can be a reliable instrument to measure anxiety in Brazilian elderly people.

Abstract Background Hemodialysis is considered a major therapeutic method for patients with chronic kidney disease. Pruritus is a common complaint of hemodialysis patients. The 5-D pruritus scale is amongst the most common tools to evaluate several dimensions of itch. Psychometric properties of the 5-D scale have not been evaluated in Persian speaking population with hemodialysis; hence, the objective of this study was to assess reliability and validity of the Persian version of the scale. Methods Ninety hemodialysis patients (men: 50, women: 40, mean age: 54.4 years) participated in this cross-sectional study. The final Persian version of 5-D scale was given to the participants. Tests Compared: One-third of the participants completed the scale twice within 3–7 days apart to evaluate test- retest reliability. Other psychometric properties including internal consistency, absolute reliability, convergent, discriminative and construct validity, floor/ceiling effects were also evaluated. Results The Persian 5-D scale has strong test-retest reliability (ICC= 0.98) and internal consistency (Cronbach’s alpha= 0.99). Standard error of measurement and minimal detectable change were 0.33 and 0.91, respectively. Regarding convergent validity, the scale had moderate correlation with numeric rating scale (r =0.67) and quality of life questionnaire related to itch (r = 0.59). Exploratory factor analysis revealed two factors within the scale. No floor or ceiling effect was found for the scale. Conclusion The Persian version of 5-D the itching scale is a brief instrument with acceptable reliability and validity. Therefore, the scale could be used by experts, nurses, and other health service providers to evaluate pruritus among Persian speaking hemodialysis patients.

Abstract Background Critical thinking disposition helps medical students and professionals overcome the effects of personal values and beliefs when exercising clinical judgment. The lack of effective instruments to measure critical thinking disposition in medical students has become an obstacle for training and evaluating students in undergraduate programs in China. The aim of this study was to evaluate the psychometric properties of the CTDA test. Methods A total of 278 students participated in this study and responded to the CTDA test. Cronbach’s α coefficient, internal consistency, test-retest reliability, floor effects and ceiling effects were measured to assess the reliability of the questionnaire. Construct validity of the pre-specified three-domain structure of the CTDA was evaluated by explanatory factor analysis (EFA) and confirmatory factor analysis (CFA). The convergent validity and discriminant validity were also analyzed. Results Cronbach’s alpha coefficient for the entire questionnaire was calculated to be 0.92, all of the domains showed acceptable internal consistency (0.81–0.86), and the test-retest reliability indicated acceptable intra-class correlation coefficients (ICCs) (0.93, p < 0.01). The EFA and the CFA demonstrated that the three-domain model fitted the data adequately. The test showed satisfactory convergent and discriminant validity. Conclusions The CTDA is a reliable and valid questionnaire to evaluate the disposition of medical students towards critical thinking in China and can reasonably be applied in critical thinking programs and medical education research.

e24027 Background: The ongoing two-part phase 2/3 RESILIENT study (NCT03088813) is investigating the efficacy and safety of liposomal irinotecan monotherapy in patients with SCLC who have progressed on or after first line platinum-based chemotherapy. This exploratory analysis from RESILIENT part 1 was conducted to confirm the psychometric properties of established PRO instruments that had not previously been validated in patients with SCLC. Methods: Patients completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) Core 30 (C30) and the EORTC QLQ Lung Cancer 13 (LC13) before treatment assignment (baseline), every 6 weeks thereafter, at treatment discontinuation and at the 30-day follow-up visit. Psychometric methods included descriptive statistics (items and scales), correlations (item-to-item and item-to-total), internal consistency (Cronbach’s α), test-retest reliability (intraclass correlation coefficient [ICC], two-way random effects model), construct validity and sensitivity to change. The analysis included patients who received at least one dose of study drug and completed at least one PRO assessment. Results: Thirty patients were enrolled in RESILIENT part 1 and included in the analysis. At baseline, 68% of patients reported ‘not severe’ or ‘mild’ symptoms. Floor effects (i.e. more than 25% of responses of ‘not at all’) were observed for several of the functioning/impact and symptom scales of the EORTC QLQ C30 and LC13. Moderate to strong correlations were found among most questionnaire items within their respective scales. Acceptable evidence for internal consistency and good test-retest reliability were observed. Selected results for the EORTC QLQ LC13, including dyspnea scales, are shown in the Table. The magnitude of correlations among PRO instruments supported evidence for convergent validity in this sample. Conclusions: In RESILIENT part 1, patients experienced low and tolerable symptoms at enrollment, limiting the potential for further improvement. Overall, these PRO instruments had acceptable psychometric properties (e.g. construct validity, reliability and ability to detect change) in this sample. However, these analyses should be repeated in a larger sample using data from RESILIENT part 2. Clinical trial information: NCT03088813. [Table: see text]

Background: The Podiatric Health Questionnaire (PHQ) is a health-related questionnaire consisting of six questions designed for measuring foot health status. To date, the PHQ has only been validated in the English-language version. Thus, this study aimed to perform the Spanish translation and test–retest procedures of the PHQ (PHQ-S). Method: The forward/backward translation and test–retest reliability methods were applied from English to Spanish languages. Regarding the total score for each domain, internal consistency and reliability were determined by the Cronbach α and intraclass correlation coefficient (ICC) with a confidence interval (CI) of 95%. Results: High internal consistency was shown for the six domains: (1) walking with a Cronbach α of 0.97; (2) hygiene and nail care with 0.93 and 093, respectively; (3) foot pain with 0.91; (4) worry and concern domain with 0.904; (5) quality of life with 0.87; and (6) the self-perception of how their feet are feeling measured by a visual analogic scale with 0.92. Excellent test–retest reliability (ICC = 0.99 (95% CI = 0.96–0.98)) was shown for the total score. Conclusions: The PHQ-S was shown to be a valid and reliable tool for an acceptable use in the Spanish population.

Background: This study aimed to translate and validate the Fear of Cancer Recurrence Inventory (FCRI) questionnaire into Persian and to investigate its psychometric properties. Methods: The FCRI was translated to Persian using a linguistic methodology according to WHO guidelines. A total of 450 breast cancer survivors who had the following inclusion criteria were included: time elapse of more than six months after the treatment prior to the study; absence ofobjective markers of recurrence, fluency in the Persian language, and signing the informed consent. Internal consistency was estimated with Cronbach's α coefficient and test-retest reliability with Interclass correlation.  Concurrent validity was estimated through Pearson’s correlation between the FCRI and Hospital Anxiety and Depression Scale (HADS). Principal component analysis (PCA) and confirmatory factor analysis (CFA) were employed to evaluate dimensionality. Results: The Persian version was acceptable for patients. The content validity index (CVI) was 0.80.  The instrument had good test-retest reliability (ICC= 0.96) and internal consistency (Cronbach’s α=0.86).  PCA and CFA indicated that the factor structure of the Persian version was similar to the original questionnaire and had acceptable goodness of fit.  Correlations between the FCRI and HADS was remarkable (r= 0.252 – 0.639), indicating acceptable concurrent validity. Conclusions: The Persian version of FCRI could be considered a good cross-cultural equivalent for the original English version. The questionnaire was a reliable and valid instrument in terms of internal consistency, test-retest reliability, and dimensionality.

Background: The Sexual Interest and Desire Inventory Female (SIDI-F) is a clinician-administered scale that allows for a comprehensive assessment of symptoms related to Hypoactive Sexual Desire Dysfunction (HSDD). As self-report questionnaires may facilitate less socially desirable responding and as time and resources are scarce in many clinical and research settings, a self-report version was developed (SIDI-F-SR). Aim: To investigate the agreement between the SIDI-F and a self-report version (SIDI-F-SR) and assess psychometric properties of the SIDI-F-SR. Methods: A total of 170 women (Mage=36.61, SD=10.61, range=20-69) with HSDD provided data on the SIDI-F, administered by a clinical psychologist via telephone, and the SIDI-F-SR, delivered as an Internet-based questionnaire. A subset of 19 women answered the SIDI-F-SR twice over a period of 14 weeks. Outcomes: Intraclass correlation as well as predictors of absolute agreement between SIDI-F and SIDI-F-SR, as well as internal consistency, test-retest reliability, and criterion-related validity of the SIDI-F-SR were examined. Results: There was high agreement between SIDI-F and SIDI-F-SR (ICC=.86). On average, women scored about one point higher in the self-report vs. the clinician-administered scale. Agreement was higher in young women and those with severe symptoms. Internal consistency of the SIDI-F-SR was acceptable (α=.76) and comparable to the SIDI-F (α=.74). When corrections for the restriction of range were applied, internal consistency of the SIDI-F-SR increased to .91. Test-retest-reliability was good (r=.74). Criterion-related validity was low but comparable between SIDI-F and SIDI-F-SR.

ObjectiveEven though continuity is essential after discharge, there is a lack of reliable questionnaires to measure and assess patients’ perceptions of continuity of care. The Patient Continuity of Care Questionnaire (PCCQ) addresses the period before and after discharge from hospital. However, previous studies show that the factor structure needs to be confirmed and validated in larger samples, and the aim of this study was to evaluate the psychometric properties of the PCCQ with focus on factor structure, internal consistency and stability.DesignA psychometric evaluation study. The questionnaire was translated into Swedish using a forward–backward technique and culturally adapted through cognitive interviews (n=12) and reviewed by researchers (n=8).SettingData were collected in four healthcare settings in two Swedish counties.ParticipantsA consecutive sampling procedure included 725 patients discharged after hospitalisation due to angina, acute myocardial infarction, heart failure or atrial fibrillation.MeasurementTo evaluate the factor structure, confirmatory factor analyses based on polychoric correlations were performed (n=721). Internal consistency was evaluated by ordinal alpha. Test–retest reliability (n=289) was assessed with intraclass correlation coefficient (ICC).ResultsThe original six-factor structure was overall confirmed, but minor refinements were required to reach satisfactory model fit. The standardised factor loadings ranged between 0.68 and 0.94, and ordinal alpha ranged between 0.82 and 0.95. All subscales demonstrated satisfactory test–retest reliability (ICC=0.76–0.94).ConclusionThe revised version of the PCCQ showed sound psychometric properties and is ready to be used to measure perceptions of continuity of care. High ordinal alpha in some subscales indicates that a shorter version of the questionnaire can be developed.

Objective: To test the Brazilian Portuguese velopharyngeal insufficiency (VPI) Effects on Life Outcome (VELO) instrument for reliability and validity. Design: Cross-sectional methodological study. Setting: Tertiary craniofacial medical center. Participants: Participants with VPI (VPI group, n = 60), with cleft and without VPI (no VPI/cleft group, n = 60), and with no cleft nor VPI (no VPI/no cleft group, n = 60) and their parents (n = 180). Interventions: All patients with VPI 8+ years old and their parents completed the Brazilian–Portuguese VELO instrument and other questionnaires (Pediatric Quality of Life Inventory4.0, PedsQL4.0; Pediatric Voice-Related Quality of Life, PVRQOL; and Intelligibility in Context Scale, ICS) at baseline; patients with VPI and their parents completed the VELO instrument again 2 weeks later. Main Outcome Measures: The VELO instrument was tested for internal consistency, test–retest reliability, discriminant validity (participants with VPI against participants with no VPI), concurrent validity against other questionnaires, criterion validity against hypernasality severity, and construct validity against nasal air emission and overall velopharyngeal competence (speech construct) and velopharyngeal gap (anatomic construct). Results: The VELO had excellent internal consistency (Cronbach α 0.99 for parents and 0.98 for participants with VPI) and test–retest reliability (all intraclass correlation coefficient > 0.87). The VELO discriminated well between VPI group and unaffected groups (all P < .05). The VELO was significantly correlated with the PedsQL4.0, PVRQOL, and ICS (– r > 0.75; P < .001). The VELO met criterion validity, speech construct validity, and anatomic construct validity ( r > 0.7; P < .001). Conclusions: The Brazilian-Portuguese VELO instrument demonstrated reliability (internal consistency and test–retest) and validity (discriminant, concurrent, criterion, and construct).
