The Brazilian version of Skindex-16 is a valid and reliable instrument to assess the health-related quality of life of patients with skin diseases.

ABSTRACT:

Introduction

The aim of this study was to assess the psychometric properties of the Brazilian version of Skindex-16 in patients with various skin diseases.

Methods

Dermatologic assessments were performed for the diagnosis and classification of the severity of skin conditions. The clinical feasibility of Skindex-16 was assessed based on the time required to complete the questionnaire and the number of unanswered items. The participants (n = 110) answered the Hospital Anxiety and Depression Scale (HADS), the Dermatology Life Quality Index (DLQI) and the Skindex-16 (Portuguese/Brazil version) questionnaires. Convergent validity was assessed based on the correlation of the Skindex-16 with the DLQI and HADS subscales. Known-groups validity was assessed based on the comparison of the mild, moderate and severe disease groups using the Kruskal-Wallis test. Internal consistency was assessed using Cronbach's alpha and test-retest reproducibility using the intraclass correlation coefficient (ICC) obtained with 29 participants who answered the Skindex-16 a second time 3 to 10 days after the first assessment.

Results

The mean time to answer the questionnaire was 2 min 41 sec. Cronbach's alpha scores were 0.867, 0.930 and 0.888 for the Skindex-16 domains symptoms, emotions and functioning, respectively. The ICCs were 0.947, 0.860 and 0.843 for the Skindex-16 domains symptoms, emotions and functioning, respectively. All three Skindex-16 scales exhibited strong correlations with DLQI. Moderate correlations were found between HADS subscales and the Skindex-16 emotions domain. Known-groups validity showed differences in all three Skindex-16 domains between the mild and moderate skin disease groups (emotions: p < 0.001; symptoms: p = 0.049; functioning: p < 0.001) and between the mild and severe skin disease groups (emotions: p = 0.002; symptoms: p = 0.001; functioning: p = 0.002).

Conclusion

The Portuguese/Brazil version of Skindex-16 is a valid and reliable instrument to assess the quality of life of patients with skin diseases.

Project description:BackgroundFor newborns and infants wearing diapers the difficulties in characterizing the appearance of the stool are significant, since the changes in consistency, quantity, and color of the stool are higher than in other age groups. The Amsterdam Infant Stool Scale (AISS) was created and validated in 2009, providing a specific tool for the evaluation of the stool of children up to 120 days old. However, to be used in clinical practice and scientific investigations in Brazil, it is mandatory to perform the translation and cross-cultural adaptation process for Brazilian Portuguese language. Thus, we aim to perform the translation and cross-cultural adaptation of AISS into Brazilian Portuguese and to evaluate the psychometric properties of the translated version.MethodsThe process of translation and cross-cultural adaptation was performed according to the internationally accepted methodology, including: translation, summary of translations, backtranslation, preparation of the pre-final version, application of the pre-test and determination of the final version. The evaluation of the psychometric properties was performed through the application of Brazilian Portuguese AISS, by five examiners (including child health field specialists and a literate adult lay on the subject), analyzing 238 stool photographs of children under 120 days old. The intra and inter-examiner agreement values were determined using kappa statistic. The validity of the criterion was investigated through correlation analysis (Kendall's coefficient) between the classifications determined by the non-specialist examiner and the expert examiners.ResultsIn all 30 tests performed between different examiners, there was an agreement considered as at least moderate (kappa values above 0.40). The intra-examiner reliability was considered as substantial (kappa> 0.6). There was a statistically significant correlation (p < 0.05) between the classifications determined by the examiners considered as specialists and the examiner considered as non-specialist.ConclusionThe Brazilian Portuguese AISS version proved to be valid and reliable to be used by healthcare professionals and the general public in the evaluation of stool from children up to 120 days old.

Project description:BackgroundPeople's sexual experiences have a strong association with contraceptive satisfaction and continuation, but no measures exist to specifically assess contraceptive-related sexual acceptability.AimThis study developed and examined the psychometric properties of reliability, separation, and item fit of a new Contraceptive Sexual Acceptability (CSA) instrument.MethodsEnrolled participants initiating a new contraceptive method from the HER Salt Lake longitudinal cohort study contributed baseline survey responses for scale development. The study included the Female Sexual Function Index, the New Sexual Satisfaction Scale, measures of physical and mood-related side effects, and self-reported perceptions of contraception's sexual impacts. Items from these measures' served as the basis for analyses. We analyzed responses using descriptive techniques and modeled using exploratory factor (EFA) and bifactor analyses (BFA). The Masters' Partial Credit Rasch method modeled reliability, separation, and item fit statistics. Here we evaluate (i) the reproducibility of relative measure location on the modeled linear latent variable, (ii) the number of statistically unique performance levels that can be distinguished by the measure, and (iii) the discrepancy between item responses and expectations of the model. Psychometric findings and theoretical models informed item reduction and final scale development.OutcomesWe developed a 10-item Contraceptive Sexual Acceptability scale that exceeded the thresholds and sufficiently covered domains for use in contraceptive research and clinical settings.ResultsStarting with data on 39-items from 4,387 individuals, we identified 10-items that best measured the CSA latent construct. The Rasch model included a total of 5 calibrations. We reduced items based on bifactor analysis and surpassed unidimensionality thresholds (OH = 0.84, ECV = 0.74) set a priori. The final items included questions with scaled responses about pleasure and orgasm (orgasm quality, orgasm frequency, giving partner pleasure), physical (arousal and function) and psychological (emotional connection, surrender) components, general questions of satisfaction and frequency, and a measure of perceived impact of contraception on sexual experiences in the previous 4 weeks.Clinical implicationsThe 10-item CSA instrument covers physical and psychological aspects of contraceptive sexual acceptability and can be used in clinical settings.Strengths & limitationsThe unidimensional CSA instrument offers a brief, yet comprehensive assessment of sexual acceptability. Given the limited diversity of the sample, implementation of this scale in contraceptive research and clinical interactions should be evaluated and validated in more diverse settings.ConclusionAttuning to sexual acceptability could ultimately help contraceptive clients find methods that better meet their needs and preferences.
