Smartphone use side-by-side with burnout: mediation of work-family interaction and loneliness

The main objective of this investigation is to study the relationship between compulsive smartphone use and burnout, and the potential mediating effect of negative work–family interaction and loneliness in this relationship. An online questionnaire was applied to a sample of 228 Portuguese workers, from various sectors, aged between 19 and 60 years (mean = 32.32); (standard deviation = 9.25), mostly female (64.5%; n = 154). The data were analyzed through descriptive and inferential statistics. The main results show that the compulsive use of the smartphone is positively and expressively related (β = 0.258; p < 0.001) to burnout, with compulsive users reporting more symptoms of burnout. In addition, this study shows the mediating power of negative work–family interaction and loneliness, in the relationship between compulsive smartphone use and burnout, with this effect being positive and significant (B = 0.072; 95% CI [0.026; 0.145]; B = 0.068; 95% CI [0.008; 0.141]). These results highlight the need for individuals and organizations to use smartphones with caution, as well as reinforce that companies must develop a way to prevent and treat possible risk factors associated with this phenomenon.info:eu-repo/semantics/publishedVersio

Are we getting less sexist? a ten-year gap comparison analysis of sexism in a Portuguese sample

Widely and slowly, discrimination against women based upon gender has become socially unacceptable. However, less is known about how sexist beliefs have progressed in the last years and if we are responding to this social antagonizing of a sexist discourse. Our goal was to verify the existence of differences in ambivalent sexism and neosexism over a ten-year gap in a Portuguese adult sample and to assess possible modifications in the relationship between the variables. A cross-sectional, correlational study was conducted using two independent groups, with measures taken in 2009 and then in 2019. Both groups were invariant in terms of average age and proportion of sexes. Our results show a decrease in hostile and benevolent forms of sexism, while neosexism remains constant. The relationships between variables suggest that sexist beliefs are changing to accommodate subtler and modernized forms of sexism, like neosexism, that deny the existence of discrimination against women, resent discrimination complaints, and maintain a paternalistic view of women. Neosexism also seems to have a stronger correlation with hostile sexism than with benevolent forms of sexism in the male subsample. This relationship is stronger for the 2019 sample. These relationships suggest that sexism is more deeply rooted than we would like to admit and adapts to social discourse. Despite our best efforts, it is yet to be overcome.info:eu-repo/semantics/publishedVersio
