Evidência de validade para a escala de percepção do suporte social (versão adulta) - epsus-a: um estudo correlacional / Evidence regarding the validity of the scale of perceived social support (adult version): a correlational study / Pruebas de validez de la escala de percepción del apoyo social (versión para adultos) - epsus-a: un estudio correlacional

A presente pesquisa teve como objetivo a busca por evidência de validade com base na relação com variáveis externas para a Escala de Percepção do Suporte Social (versão adulto) - EPSUS-A, por meio da análise de correlação com os instrumentos Inventário de Percepção do Suporte Familiar (IPSF) e a Escala Baptista de Depressão (versão adulta) – EBADEP-A. A amostra do estudo foi composta por 102 universitários, com idade variando entre 18 e 61 anos (M = 26,59, DP = 9,57). Dos resultados, quanto às análises de correlação entre os instrumentos, todas as dimensões da EPSUS-A se correlacionaram de forma positiva e significativa em relação às dimensões do IPSF, assim como todas os fatores da EPSUS-A apresentaram correlações negativas e significativas com a EBADEP-A, evidenciando, dessa forma, validade em relação às variáveis externas da EPSUS-A.

This study aimed to establish evidence regarding the validity (based on the relationship with external variables) of the Scale of Perceived Social Support (Adult Version, EPSUS-A) through a correlation analysis with the Perception Inventory Instruments of Family Support (IPSF) and the Baptista Depression Scale (Adult Version, EBADEP-A). The study sample comprised 102 students aged 18–61 years (M = 26.59, SD = 9.57). The results of the correlation analysis between the instruments show that all the dimensions of the EPSUS-A correlated positively and significantly with that of the IPSF. However, all the factors of the EPSUS correlated negatively and significantly with the EBADEP-A, thus depicting validity in the relationship with the external variables of the EPSUS.

Reliability and Validity of a Chinese Version of Urinary Tract Infection Symptom Assessment Questionnaire

ABSTRACTObjectives:Our study evaluates the reliability and validity of a Chinese version of the Urinary Tract Infection Symptom Assessment questionnaire (UTISA).Material and Methods:Our study enrolled women who were diagnosed with uncomplicated urinary tract infection (uUTI) at clinics. The Chinese version of UTISA was completed upon first visit to the clinic for uUTI and at 1-week follow-up. We enrolled 124 age-matched women without uUTI from the community as the control group. The UTISA consists of 14 items (seven symptom items and seven related to quality of life), with each item scoring 0 to 3. The internal consistency was assessed with Chronbach's alpha test. Factor analysis was used to classify symptoms into latent factors. The predictive validity was analyzed by using logistic regression and Receiver Operating Characteristic (ROC) curve analysis.Results:Mean total symptom scores of the UTISA in the 169 cases and 124 controls were 8.9±4.6 and 1.4±2.4, respectively (p<0.01). The alpha coefficient was 0.77, showing a homogeneous composition of symptoms. At a cut-off value of greater than 3, the UTISA symptom score had good predictive value for uUTI (sensitivity of 87.0%, and specificity of 93.1%). Factor analysis revealed two latent variables: 1) lower urinary tract symptoms and 2) physical symptoms. Among the seven items, we found that urinary frequency (OR=2.6), dysuria (OR=5.0), sense of incomplete emptying (OR=2.0), and hematuria (OR=7.6) were significant predictors for uUTI.Conclusions:The Chinese version of UTISA is reliable to predict uncomplicated UTI in women with an optimal cut-off point at >3.
