Psychological responses to COVID-19 in a Mexican population: an exploratory study during second and third phases.

This work constitutes an exploratory study during the second and third phases of COVID-19 in Mexico, characterized by local transmission and untraceable cases, respectively, with an incidental sample of 666 participants. The 21-item Depression Anxiety Stress Scale was used to assess depression, anxiety and stress associated to COVID-19. Additionally, the Impact of the Event Scale-Revised was applied to assess the impact of the event, and the 10-item Connor-Davidson Resilience Scale was employed to assess resilience. Participants' levels of traumatic impact (21.7%), severe depression (7%), severe anxiety (9.4%) and severe stress (5.4%) were revealed to be lower than other populations. Comparison of means and effect size η2p of the data shows that women and young people (18-39 years) suffer the greatest negative effects. Individuals with higher levels of resilience experience fewer psychological consequences confirming its importance in the face of the adversities. These findings provide valuable information on the impact of COVID-19 pandemic in the Mexican population, allowing a comparative analysis at an international level which can be helpful in the development of appropriate sanitary policies.

Validación del "Índice de calidad de vida, versión en español" (QLISp) en una muestra mexicana / Validation of the Quality of Life Index, Spanish Version (QLI-Sp) in a Mexican sample

El objetivo de este estudio fue la validación del "Índice de calidad de vida, versión en español" (QLI-Sp), con una muestra no aleatoria de 3384 estudiantes del nivel técnico y universitario que informaron estar sanos, además, se recogieron datos de 386 estudiantes que informaron tener hipertensión. Se utilizó una batería de pruebas psicológicas que median calidad de vida, bienestar psicológico, satisfacción con la vida y estrés académico. Los análisis factoriales exploratorio y confirmatorio ratificaron la naturaleza unifactorial del QLI-Sp apoyando su uso para medir percepción de calidad de vida en estudiantes universitarios. La fiabilidad fue adecuada (alfa= 0.93). Para explorar más la validez del QLI-Sp, se examinaron los datos de 396 estudiantes que informaron hipertensión. El grupo relativamente sano tuvo puntuaciones más altas en todos los ítems del QLI-Sp en comparación con el grupo hipertenso. El modelo final indicó que la calidad de vida se relaciona de manera positiva con el bienestar psicológico (autopercepción, autonomía, dominio del entorno, propósito en la vida) y la satisfacción con la vida, y de manera negativa con el estrés académico

The objective of this study was the validation of the Spanish version of the Quality of Life Index. A non-random sample of 3384 technical and university level healthy students was selected, in addition, data were collected from 386 students who reported being hypertensive. A battery of psychological tests that mediate quality of life, psychological well-being and life satisfaction as well as a measure of academic stress were included. The exploratory and confirmatory factor analysis confirmed the unifactorial nature of the QLI-Sp and support its use to measure perception of quality of life in university students. The reliability was adequate ( alpha=0.93). To further explore the validity of the QLI-Sp, data from 396 students who reported being hypertensive were examined. The relatively healthy group had higher scores on all QLI-Sp items relative to the hypertensive group. In the final model, positive correlations were found between the QLI-Sp items with psychological well-being (self-perception, autonomy, mastery of the environment, purpose in life), with satisfaction with life and negative correlation with academic stress
