En el presente trabajo abordamos la forma cómo la estadística puede ayudar en cada una de las etapas del proceso de investigación científica, desde el planteamiento del problema hasta la obtención de las conclusiones finales. La metodología utilizada es del tipo documental. Los resultados a los que hemos llegado lo podríamos sintetizar en que la estadística es una ciencia que se ocupa del estudio de fenómenos de tipo genérico, normalmente complejos y enmarcados en un universo variable, mediante el empleo de modelos de reducción de la información y de análisis de validación de los resultados en términos de representatividad, que la investigación científica es un proceso sistemático y controlado de constante exploración y descubrimiento, fundamentado en el método científico y comúnmente, dirigido hacia la solución de un problema, que el método científico se fundame...

The COVID-19 pandemic has greatly affected the mental health of children and adolescents. In Peru, due to containment measures, children and adolescents were subjected to two years of virtual education, further affecting their socioemotional development. The use of the 17-item Pediatric Symptom Checklist (PSC-17) allows early detection of mental health problems in children and adolescents. Objective: To determine the psychometric characteristics of the Peruvian adaptation of the Pediatric Symptom Checklist-17 (PSC-17). Methods: Data were collected from 561 Peruvian schoolchildren (53.3% female; average age=12.23, SD=2.65) who completed the PSC-17 through telephone or video calls made between November 2021 and January 2022. Results: The PSC-17 internal consistency analysis showed a McDonald omega coefficient of 0.7098, indicating acceptable reliability of the instrument. Within the struct...

Objective: To assess the mental health of children and adolescents in connection with virtual education during the COVID-19 pandemic in Peru, using the PSC-17 scale. Materials and methods: Schoolchildren completed the Peruvian version of the PSC-17 through telephone calls or video calls between November 2021 and January 2022. The Chi-square test was used to evaluate the difference in the distribution of psychosocial problems between groups, and binary logistic regression to explore the possibly associated risk factors. Statistical analysis was performed through SPSS 22.0. Results: A total of 561 valid questionnaires were collected from 13 public and private schools. 52,6% of the proband schoolchildren presented diverse levels of stress, sadness, or irritability; and 34,8% expressed that the most demanding factor was the learning modality. 28,5% were at risk of presenting mental health pr...
