Depression is a significant public health problem, which makes it necessary to understand the psychometric properties of the instruments used for its evaluation to facilitate better decision-making. The Patient Health Questionnaire (PHQ-9) is an instrument that achieves optimal accuracy levels in measuring depression. Therefore, the objective of this study was to conduct a meta-analysis to generalize its reliability. A systematic search conducted in Web of Science and Scopus between 2020 and 2022 retrieved 32 studies that applied the PHQ-9 and reported Cronbach's alpha. A random effects meta-analysis was performed to estimate the test reliability, while heterogeneity was assessed using Cochran's Q and I2 statistics. Potential moderating variables were examined through meta-regression and subgroup analyses. The combined reliability of the PHQ-9 was 0.846 (95% CI: 0.824-0.862). The Egger t...

Se estudió la validación de la Escala de Apoyo Social Percibido. La población fue de 435 adolescentes escolares de 12 a 17 años del distrito de San Martín de Porres. Los resultados señalan en el análisis de ítems coeficientes de correlación ítem- test mayores a .40, lo cual indica la relación de los ítems con la escala. La validez de contenido por el método del criterio de jueces evaluó los 12 ítems, obteniéndose coeficientes V de Aiken de .80 a 1.00; indicando que la escala en su conjunto mide el dominio teórico relacionado con el apoyo social percibido. La validez de constructo validó el modelo teórico de la escala confirmando los 3 factores: amigos, persona significativa y familia; explicando el 67% de la varianza total. La confiabilidad por estabilidad temporal obtuvo un CCI de .56 y la consistencia interna un coeficiente alfa ordinal aceptable de .86 señalando la...

A sample of 212 students was taken of the marginal-urban area of San Martin de Porres district, located in Lima, aged between 6 and 11 years, who were attending a state primary school. A checklist was applied, (validated by the authors) made up by l8 items under DSM IV criteria. The results indicated a prevalence of 16.5 % (IC 95 %=10.7 %-22.3 %), the most predominant type was combined, in boys and the age group of 6 to 8 years. It was also identified that in boys predominate the combined type and the hyperactive one, while the inattentive type is more prevalent in girls.

El objetivo del estudio fue desarrollar una versión corta del PANAS, a partir de la versión original de 20 ítems, propuesta por Watson et al (1988). La muestra fue de 3960 estudiantes de una universidad pública de Lima. Los resultados señalan que la validez de estructura interna, a través del análisis exploratorio y confirmatorio, quedó definida por 10 ítems y dos dimensiones; Las emociones positivas incluyen 5 ítems: decidido, optimista, inspirado, activo, atento y las emociones negativas 5 ítems; irritable, hostil, enojado, culpable, avergonzado. Asimismo, se encontró que los coeficientes estandarizados de los enunciados reportaron valores entre 0.48 y 0.85, así como los índices de ajuste del modelo estuvieron de acuerdo a lo esperado. La confiabilidad por consistencia interna señala coeficientes Alpha y omega mayor a 0.70 en ambos factores.

The objective of the study was to develop a short version of the Positive Affect and Negative Affect Scale (PANAS), from the original version of 20 items, proposed by Watson et al. (1988a). The sample consisted of 3960 students from a public university in Lima. The results indicate that the validity of the internal structure, through exploratory and confirmatory factor analysis, was defined by 10 items and two dimensions. Positive affects are organized into five items: determined, optimistic, inspired, active, and attentive; while negative affects are in five items: irritable, hostile, angry, guilty, and ashamed. Likewise, it was found for the final short version, standardized coefficients with factorial loads between .48 and .85, as well as the fit indices of the model were in accordance with what was expected. Internal consistency reliability indicates Alpha and Omega coefficients grea...

The principal aim of the study was evidences of the validity offered psicométrica of the Gestáltico Visomotor Bender’s Test (TGV) and the System of Qualification of Gradual Punctuation (B-SPG). In this respect the maturity was appraised visomotora at 108 children of both sexes by ages understood between 6 and 10 years of primary age of mixed colleges of level of Metropolitan Lima and to compare these results with an equal sample (108) of children of the condition of Sao Paulo State in Brazil. Thinking that Bender’s TGV with the B-SPG is a consistent test where all the articles contribute to the test. Significant differences being observed in function to the age where to major minor age number of mistakes and minor total score. This inversely proportional relation between the age and the number of mistakes was described as method to measure the maturity visomotora and was establishe...
