SUMMARYThe growing number of publications on the subject of burnout syndrome suggests this is the most widely researched psychological workrelated outcome in the last decades. It is important to review the state of art in this phenomenon and to examine the challenging dimension that it has reached. The general objective of this paper was to carry out a systematic review of the published literature in order to characterize burnout research in Mexico. MethodsA manual search was carried out in 12 databases including Spanish or Latin American journals. All the existent articles up to July 2012 were taken into account and five criteria were defined so as to assure the comparability among the studies. Meta-analyses were estimated with the averages of the burnout dimensions and the Cronbach alpha coefficients reported. ResultsSixty-four studies were selected (n=13 801 employees); most of them were from health professionals and more than half were collected in Jalisco and Distrito Federal. The methodological analyses revealed that more than 90% of the studies were observational/cross-sectional designs, and most with data analyses that are vulnerable to the effect of confounding variables. A remarkable finding was the huge heterogeneity in the criteria used to determine the prevalence of burnout. The meta-analyses in 14 selected studies showed average burnout symptoms values of "once a month or less" within the frequency scale. DiscussionThe general balance of this review shows that the research on burnout in Mexico still has areas of opportunity. It is necessary to broaden the range of occupations and regions to improve the methodological designs and the information analyses, and to ensure the used scales have good psychometric properties. Some recommendations for future research are offered.

Los procesos psicosociales en el trabajo incluyen factores del contexto organizacional, disposiciones psicológicas individuales, aspectos extralaborales, efectos psicológicos e indicadores de salud mental. En este manuscrito se propone un instrumento con cinco subescalas que abarcan estas dimensiones para la evaluación de procesos psicosociales (PROPSIT) en trabajadores mexicanos, y se analiza su estructura factorial como evidencia inicial de validez. Participa-ron de manera voluntaria 1339 trabajadores operativos del Estado de Morelos, quienes contestaron el instrumento por medio de una plataforma virtual. Se realizaron diversos análisis factoriales exploratorios (AFE), confirmatorios (AFC), y se estimaron los coeficientes de confiabilidad (α, ω) en cada una de las cinco subescalas. En general las subescalas obtuvieron la estructura esperada teóricamente y con índices de ajuste satisfactorios (CFI, GFI, NFI >.90; RMSEA <.08) y con niveles de confiabilidad acepta-bles (>.70). Se concluye que los puntajes obtenidos del instrumento PROPSIT poseen validez estructural y confiabilidad, y pueden ser una alternativa para la medición integral de procesos psicosociales en muestras de trabajadores similares. Se recomiendan más estudios en diferentes sectores y poblaciones ocupacionales

The relation between job stress and BP is significant in the Mexican population and highlights the association between job insecurity and cardiovascular indicators, indicating its importance in the Mexican work context. Future studies are suggested, as well as the prevention and surveillance of these factors in occupational and public health fields in terms of their role in cardiovascular epidemiology.

La pandemia de COVID-19 es un reto enorme para la salud pública y la economía mundial; también es un reto mayor para la salud mental, siendo uno de los grupos potencialmente más afectados el personal de salud. Uno de los efectos que ya se observa entre los trabajadores de este grupo ocupacional es el síndrome de burnout. En este artículo se revisa el origen del síndrome de burnout entre el personal sanitario, su importancia en el contexto de la pandemia y se proponen estrategias para disminuir o controlar su ocurrencia.

Although the validity of the ERIQ' scales were generally satisfactory in most Latin-American samples, future research should examine in depth the equivalence of reward scale across Latin-American cultures.
