    Sex-related differences in the associations between diurnal cortisol pattern and social and emotional loneliness in older adults

    Loneliness is a distressful feeling that can affect mental and physical health, particularly among older adults. Cortisol, the primary hormone of the Hypothalamic-Pituitary-Adrenal axis (HPA-axis), may act as a biological transducer through which loneliness affects health. While most previous studies have evaluated the association between loneliness, as a unidimensional construct, and diurnal cortisol pattern, no research has examined this relationship discriminating between social and emotional loneliness in older adults. As sex differences in the negative mental health outcomes of loneliness have been reported, we also investigated whether diurnal cortisol indices and loneliness associations occur in a sex-specific manner. We analyzed the diurnal cortisol- pattern in 142 community-dwelling, non-depressed, Caucasian older adults (55,6% female) aged 60-90. Social and emotional (family and romantic) loneliness scores were assessed using the Spanish version of the Social and Emotional Loneliness Scale for Adults (SELSA). Five salivary cortisol samples were used to capture key features of the diurnal cortisol pattern, including: awakening and bedtime cortisol levels, awakening response (CAR), post-awakening cortisol output (post-awakening cortisol [i.e., the area under the curve with reference to the ground: AUCG]), total diurnal cortisol release (AUCG), and diurnal cortisol slope (DCS). After controlling for sociodemographic variables, the hierarchical linear multiple regression analyses revealed that in male older adults, higher scores on social and family loneliness were associated with elevated awakening cortisol levels, total diurnal cortisol output, and a steeper diurnal cortisol slope (DCS). However, these associations were not observed in female older adults. In addition, feelings of romantic loneliness were positively associated with bedtime cortisol levels and AUCG in older males. Multilevel growth curve modeling showed that experiencing more social and emotional loneliness predicted higher diurnal cortisol output throughout the day in older male adults. The presence of sex differences in the relationship between cortisol indices and loneliness among older adults holds particular significance for diagnostic and screening procedures. Combining loneliness scales as screening tools with diurnal cortisol measures has the potential to be an effective and cost-efficient approach in identifying higher-risk individuals at early stages

    Meta-Analysis on the Attitudes of Active Teachers About the Use of Educational Technology According to Gender
    (Bastas Publications, 2021-12-07) Guillén Gámez, Francisco David; Rodríguez Fernández, Raquel
    Studies analysing and comparing the attitudes of teachers towards Information and Communication Technologies (ICT) based on gender have provided mixed results. In this work, we carried out a meta-analysis on gender differences in attitudes towards ICT, from a global perspective and exploring four dimensions: affective-emotional attitude, beliefs, self-efficacy, and mixed with each other. Through the collection of 55 studies providing 73 effect sizes based on a total sample of 21,325 working teachers, a negative effect was found, almost null (d= -0.0297) and not statistically significant. These results indicate that female teachers have a more positive attitude towards the educational use of ICT than male teachers. Independently, the dimensions affective-emotional attitude (d= -0.342), beliefs (d= 0.114), and self-efficacy (d= 0.273) produced significant effect sizes, although with small effects. The analysis of moderating variables showed that different moderators intervene significantly in the variability of effect sizes: continental origin of the teachers (emotional and beliefs dimensions); teacher’s workplace (dimension self-efficacy); type of publication (emotional dimension) and validity of the instruments (emotional and beliefs dimension). With this meta-analysis, it is possible to take another step towards a better measurement and explanation of the attitudes that teachers have towards the use of new technologies in educational contexts.
