DEL CARPIO OVANDO, Perla Shiomara et al. Mexican Validation of the MOS Questionnaire on Perceived Social Support in the Context of the COVID-19 Pandemic. Suma Psicol. [online]. 2022, vol.29, n.2, pp.100-109.  Epub May 08, 2023. ISSN 0121-4381.


The COVID-19 pandemic has had a very negative impact on people’s overall mental health and psychosocial well-being, but the study of available social support to cope with such an adverse situation has received hardly any attention.


To examine the psychometric properties of the MOS Perceived Social Support Questionnaire among the Mexican population in the context of the COVID-19 pandemic.


Non-experimental cross-sectional study. A sociodemographic questionnaire and the Medical Outcomes Study were applied in a non-probabilistic sample. A total of 898 people from different regions in Mexico, 258 males and 640 females, participated in the study in the context of the COVID-19 pandemic.


The analysis yielded a bi-factor model with two factors, Emotional/informational support and Tangible support, with satisfactory goodness of fit indices. Reliability was adequate with a high hierarchical omega coefficient, as well as in the factors. Likewise, the H coefficient was adequate in the general factor and its dimensions.


Results showed that the scale is a valid and reliable measure of perceived social support among the Mexican population.
