This study aims to assess the psychometric properties of the Brazilian version of the Vulnerable Elders Survey-13 (VES-13). Interviews were carried out with individuals aged 60 years and over receiving care at an ambulatory cancer centre. Test-retest reliability was assessed using the Spearman correlation coefficient, intraclass correlation coefficients and Cohen's kappa coefficient. Construct validity was assessed by testing convergent and discriminant validity using principal component analysis and Varimax rotation. The Spearman correlation coefficient value of the comparison between test and retest scores was 0.98 (p < 0.001). All intraclass correlation coefficient values were higher than 0.60 and kappa coefficients varied between 0.33 and 0.94. Three identified factors explained 72.6% of overall sample variance. VES-13 presented good convergent validity and reasonable discriminant validity. The psychometric properties of the adapted version of the VES-13 are consistent and adequate for use with the Brazilian population.

Longitudinal Outcome

Background: Paratonia is a distinctive form of hypertonia, causing loss of functional mobility in early stages of dementia to severe high muscle tone and pain in the late stages. For assessing and evaluating therapeutic interventions, objective instruments are required. Objective: Determine the psychometric properties of the MyotonPRO, a portable device that objectively measures muscle properties, in dementia patients with paratonia. Methods: Muscle properties were assessed with the MyotonPRO by 2 assessors within one session and repeated by the main researcher after 30 min and again after 6 months. Receiver operating characteristic curves were constructed for all MyotonPRO outcomes to discriminate between participants with (n = 70) and without paratonia (n = 82). In the participants with paratonia, correlation coefficients were established between the MyotonPRO outcomes and the Modified Ashworth Scale for paratonia (MAS-P) and muscle palpation. In participants with paratonia, reliability (intraclass correlation coefficient) and agreement values (standard error of measurement and minimal detectable change) were established. Longitudinal outcome from participants with paratonia throughout the study (n = 48) was used to establish the sensitivity for change (correlation coefficient) and responsiveness (minimal clinical important difference). Results: Included were 152 participants with dementia (mean [standard deviation] age of 83.5 [98.2]). The area under the curve ranged from 0.60 to 0.67 indicating the MyotonPRO is able to differentiate between participants with and without paratonia. The MyotonPRO explained 10-18% of the MAS-P score and 8-14% of the palpation score. Interclass correlation coefficients for interrater reliability ranged from 0.57 to 0.75 and from 0.54 to 0.71 for intrarater. The best agreement values were found for tone, elasticity, and stiffness. The change between baseline and 6 months in the MyotonPRO outcomes explained 8-13% of the change in the MAS-P scores. The minimal clinically important difference values were all smaller than the measurement error. Conclusion: The MyotonPRO is potentially applicable for cross-sectional studies between groups of paratonia patients and appears less suitable to measure intraindividual changes in paratonia. Because of the inherent variability in movement resistance in paratonia, the outcomes from the MyotonPRO should be interpreted with care; therefore, future research should focus on additional guidelines to increase the clinical interpretation and improving reproducibility.

ABSTRACT Metamemory measures provide subjective memory information and are relevant to investigate memory ability in aging. However, there is a lack of metamemory instruments available in Brazil. Objective: The aim of this study was to examine the psychometric properties of the Brazilian version of the Multifactorial Memory Questionnaire (MMQ), which evaluates different dimensions of subjective memory functioning, such as Feelings, Abilities and Strategies used in everyday life. Methods: The MMQ was translated into Portuguese and administered to 30 Brazilian elderly subjects. The participants underwent cognitive tests, mood scales and metamemory instruments. Results: Analyses revealed good internal consistency (Cronbach's a coefficient ranged from 0.75 to 0.89) and test-retest validity for each MMQ dimensions (positive correlations between two applications ranged from 0.75 to 0.8). Convergent validity evidence for the MMQ was confirmed by significant positive correlations (0.47 to 0.68) with dimensions of the Metamemory in Adulthood scale (MIA) (i.e., the Ability, Control, Self-efficacy and Strategy dimensions). Discriminant validity revealed no associations between the MMQ and cognitive performance, suggesting a weak metamemory-objective memory correspondence. Moreover, there was a negative correlation between MMQ-Ability subscale scores and mood symptoms (-0.63 for anxious symptoms, and -0.54 for depressive symptoms); and the Brazilian MMQ was comparable with MMQ translations to other languages. Conclusion: The Brazilian MMQ exhibits good psychometric properties and appears promising for clinical and research purposes. Additional studies are needed to further examine the psychometric properties of the Brazilian MMQ in a larger sample.

Axis I

The Millon Clinical Multiaxial Inventory—II (MCMI-II), a frequently used self-report measure of psychopathology, contains nine scales designed to assess Axis I psychopathology (the clinical syndrome and severe syndrome scales). This study explored the relationships among these nine MCMI-II clinical syndrome scales and the clinical scales of the Minnesota Multiphasic Personality Inventory–2 (MMPI-2). A sample of 108 psychiatric inpatients was administered both the MCMI-II and the MMPI-2 within 7 days of admission. Pearson correlation coefficients and principal component factors were obtained for the MCMI-II and MMPI-2 scales. The results provided support for the convergent validity of all the MCMI-II Axis I scales. However, the majority of the MCMI-II scales failed to demonstrate adequate discriminant validity in relation to the MMPI-2 scales. The principal component analysis revealed that method variance was the principal influence in determining factor loadings for the majority of test scales. This finding suggests that these two popular self-report tests differ substantially in how they measure psychopathology.

PURPOSE: The Radboud Dysarthria Assessment (RDA) was published in 2014. Adaptation into a pediatric version (p-RDA) was required because of relevant differences between children and adults. The purpose of this study was to assess the feasibility of the p-RDA and to test intra-rater and inter-rater reliability as well as the validity of the two severity scales (function and activity level). METHODS: Video recordings were made of 35 participants with (suspected) dysarthria (age 4 to 17 years) while being assessed using the p-RDA. Intra-rater reliability was assessed by one, and inter-rater reliability by two experiments using the Intraclass Correlation Coefficient (ICC). Validity of the severity scales was tested by correlating the consensus scores with the independently rated scores on four communication scales, three mobility scales, and one self-care scale using Spearman correlation coefficients (r s). RESULTS: The assessment was applicable for 89% of the tested sample, with good intra-rater and inter-rater reliability (ICC = 0.88–0.98 and 0.83–0.93). The p-RDA severity scales (function and activity level) correlated from substantially to strongly with the communication scales (r s = 0.69–0.82 and 0.77–0.92) and self-care scale (r s = 0.76–0.71) and correlated substantially with the mobility scales (r s = 0.49–0.60). CONCLUSION: The feasibility, reliability and validity of the p-RDA are sufficient for clinical use.

Background: Parental self-efficacy has been found to be a critical determinant of the efficacy of interventions intended to enhance the parental management of childhood eczema. Objectives: The psychometric properties of a translated Chinese version of the Parental Self-Efficacy with Eczema Care Index (C-PASECI) were examined. Methods: The PASECI was translated in a 2-stage process involving both forward and backward translation. Subsequently, the psychometric properties of the C-PASECI were examined in a cohort of 147 Chinese parents or caregivers of children with eczema. Specifically, the internal consistency, 2-day test-retest reliability and construct validity were assessed. Results: The C-PASECI received a Cronbach’s αof 0.97, and the intraclass correlation coefficients of each item ranged from 0.93 to 0.99. Negative correlations were observed among the C-PASECI, Children’s Dermatology Life Quality Index and Scoring Atopic Dermatitis Scale scores, indicating the acceptable convergent validity of the C-PASECI. The moderate correlation observed between the C-PASECI and General Self-Efficacy Scale (Pearson’s r = 0.53, p < 0.001) reflected the acceptable concurrent validity of the C-PASECI. The results of confirmatory factor analysis supported the factorial validity of the C-PASECI. Conclusion: The C-PASECI appears to be a reliable and valid measure of parental self-efficacy in Chinese parents or caregivers of children with eczema.

Summary: The Five Factor Personality Inventory (FFPI) was translated and adapted to a Spanish population of 567 subjects. A principal component analysis using orthogonal Procrustes rotation replicated the five-component structure of the original FFPI questionnaire. The coefficients of congruence between the loading matrices obtained in the Dutch sample and the Spanish sample were also computed showing high factorial convergence. The Spanish version of the FFPI showed adequate reliability. Further, convergent and discriminant validity were studied using other well-known Big Five and PEN questionnaires. The results fully supported the psychometric properties of the FFPI questionnaire in the present population.

IntroductionNegative symptoms are found in many patients with schizophrenia, but their assessment remains delicate. Standardized assessments are therefore needed to facilitate their identification. Many tools have been developed but most of them are assessments based on observer rating. Nevertheless, patient subjective evaluation can provide an additional outcome measure and allow patients to be more engaged in their treatment. Therefore, the aim of this study is to present past and recent tools assessing the subjective experience of negative symptoms; we will particularly focus on a novel tool, the Self-evaluation of Negative Symptoms (SNS).MethodsForty-nine patients with schizophrenia and schizoaffective disorders (DSMIV) were evaluated in order to demonstrate three components of the scale's validity: face and content validities and reliability.ResultsCronbach's coefficient showed good internal consistency. Factor analysis extracted 2 factors (apathy and emotional). SNS was significantly correlated with the Scale of Assessment of Negative Symptoms and the Clinician Global Impression on severity of negative symptoms supporting good convergent validity. SNS scores were not correlated with level of insight, Parkinsonism, or with BPRS positive sub-scores in favor of good discriminant validity. Intra-subject reliability of SNS revealed excellent intraclass correlation coefficients.ConclusionThis study shows good psychometric properties of SNS as well as quite satisfactory acceptance by patients. It also demonstrates the ability of patients with schizophrenia to accurately report their own experience. Self-assessments of negative symptoms should be used more in clinical practice since they might allow patients with schizophrenia to develop appropriate coping strategies.Disclosure of interestThe author has not supplied his declaration of competing interest.

Objective. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Dental Fear Survey (DFS), previously translated to the Brazilian Portuguese language and validated.Methods. A cross-sectional study with 1,256 undergraduates from the city of Belo Horizonte, Brazil, was carried out. The DFS and a questionnaire about previous dental experiences were self-administered. Data analysis involved descriptive statistics, principal components analysis (PCA), confirmatory factor analysis (CFA), internal consistency and test-retest reliability, and construct, discriminant, and convergent validity.Results. PCA identified a three-factor structure. CFA confirmed the multidimensionality of the Brazilian version of the DFS. A modified model of the Brazilian version of the DFS fits better than the hypothesized model. The Cronbach’s alpha coefficient for the total DFS scale was 0.95.Conclusion. The DFS demonstrated acceptable construct validity, convergent validity, and discriminant validity. These results supported the reliability and validity of the DFS among Brazilian undergraduates.

Abstract Background: Fatigue is the most disabling symptom in patients with multiple sclerosis (MS). Although there is no standard tool to evaluate fatigue in clinical settings, Fatigue Impact Scale (FIS), Fatigue Severity Scale (FSS) and Multidimensional Assessment of Fatigue scale (MAF) are popular instruments for this purpose. The aim of this study was to compare the psychometric properties of the Persian versions of these scales. Methods: 130 patients with MS and 60 healthy persons participated in this study. They completed the scales on two occasions 3 days apart. Reproducibility and internal consistency were evaluated as intraclass correlation coefficients (ICC) and Cronbach's alpha. Convergent validity was assessed by evaluating the association of the fatigue scales with age, sex, Expanded Disability Status Scale (EDSS), disease duration, and sleep quality. Dimensionality was evaluated with confirmatory factor analysis. Acceptability and known-group validity were also investigated. The effect size of all the scales was computed as well. Results: The ICC of all instruments was 0.99. Internal consistency was 0.97 for MAF, 0.93 for FSS, and 0.83 for FIS. The instruments showed moderate to good correlations with Pittsburgh Sleep Quality Index, EDSS, and duration of disease. Acceptability was acceptable. The FIS had three dimensions, and FSS and MAF were unidimensional. All scales were able to discriminate patients with MS from healthy people. Conclusions: The Persian version of MAF appears to be the most suitable instrument to evaluate fatigue in patients with MS based on its time-efficiency, effect size and detailed data about various aspects of fatigue.
