Stress has a negative impact on cognitive functioning and occupational well-being. The aim of this study was to assess the relationship among perceived stress, cognitive complaints and work engagement in public employees from Córdoba, Argentina. In this cross-sectional study, self-report questionnaires were administered to 240 participants. Spanish versions of the following instruments were used: Perceived Stress Scale (PSS), Utrecht Work Engagement Scale (UWES), Memory Failures in Everyday (MFE), Executive Complaint Questionnaire (ECQ). Statistical analysis included ANOVA, path analysis, and multiple logistic regression. Stressed workers showed lower work engagement and more cognitive complaints, even after adjusting for demographic variables. Negative associations were also observed between work engagement and cognitive complaints, suggesting that cognitive difficulties are related to engagement. Given the relation among stress, cognition, and work engagement, it is important to consider these factors to foster workers’ health and work productivity.

The assessment of subjective cognitive complaints (e.g., lack of initiative, difficulty for planning, attentional and memory impairment, disinhibition, etc.) that impair daily life functioning and psychopathological risk, requires integrative psychometrics. The creation of culturally relevant instruments is one of the challenges of Hispanic neuropsychology because tools developed in Latin America are scarce. Thus, the objective was to investigate the Executive Complaints Questionnaire (ECQ) psychometric properties, which is proposed herein as an appropriate multidomain instrument to assess executive functions in Spanish speakers (N ϭ 672) from Argentina (i.e., one of the most populated Hispanic countries). They were randomly divided into 2 groups (N ϭ 336) to evaluate construct validity through exploratory and confirmatory factor analyses. The total variance depended on 3 factors: Executive Attention (23%), Behavioral Flexibility (20%), and Inhibitory Control (13%). This structure was further verified through confirmatory factor analysis and provided an adequate model. Reliability processes (i.e., Cronbach's alpha, composite reliability, and interitem correlations) indicated that the ECQ was reliable. Divergent validity was achieved and no effects of age, gender, and educational level were found. In conclusion, the ECQ is a reliable and structurally valid instrument. This is the first study that employed a self-reporting questionnaire of executive complaints that was originated in the Spanish-speaking population by integrating different fronto-executive domains. This kind of study provides the methodological approach to promote new questionnaire development and standardization of the already-existing ones to be precisely dedicated for non-English-speaking populations, who do not possess valid instruments in their native languages.

Resumen Las modificaciones neurobiológicas que experimenta la mujer durante el puerperio, junto con los consecuentes cambios psicosociales, determinan variaciones en el funcionamiento cognitivo. Con el objetivo de describir las variaciones cognitivas que ocurren durante el postparto y sus factores determinantes, se desarrolló una revisión narrativa a partir de la búsqueda bibliográfica en PubMed y Google Scholar. Se evidenció un constante crecimiento del número de publicaciones a lo largo de los años (PubMed= 186; Google Scholar= 26730). El análisis de los artículos permitió: a) Caracterizar las funciones cognitivas durante el puerperio; b) Analizar los efectos neuropsicológicos producidos por los cambios endocrinológicos y anatomofisiológicos; c) Analizar el efecto de la calidad del sueño sobre la cognición; d) Analizar las funciones cognitivas en función de las experiencias obstétricas. En conclusión, la mujer puérpera se caracteriza por presentar variaciones en sus funciones cognitivas, las cuales están determinadas por cambios estructurales, funcionales, psicológicos y sociales. Es necesario fomentar investigaciones neuropsicológicas en esta población, ya que la atención del posparto todavía se centra en el cuidado del recién nacido, sin abordar a la mujer puérpera de manera integral.
