“…However, whereas some of these findings would suggest that loneliness has decreased (e.g., increasing trends of self-esteem and extraversion; Twenge, 2001;Twenge & Campbell, 2001), others would suggest that loneliness has increased (e.g., decreasing trend in attachment security and dispositional empathy; Konrath et al, 2011Konrath et al, , 2014. However, in these reflections on changes over historical time in other psychological constructs associated with loneliness, at least two considerations should be kept in mind: First, loneliness and constructs such as extraversion, attachment security, or empathy are correlated but distinct constructs that share about 10-15% of the variance (estimated based on the correlations reported in Beadle et al, 2012;Helm et al, 2020). Second, loneliness and constructs such as extraversion, attachment security, and empathy can be cross-sectionally related in different historical years.…”
