“…Associations between family relationships and psychological well‐being are demonstrated in a large body of work regarding links between parental differential treatment, and well‐being in childhood, adolescence, and early adulthood (Jensen, Whiteman, Fingerman, & Birditt, 2013; Richmond, Stocker, & Rienks, 2005; Shanahan, McHale, Crouter, & Osgood, 2008). Recently, this line of research has been extended into midlife (Davey, Tucker, Fingerman, & Savla, 2009; Pillemer, Suitor, Pardo, & Henderson, 2010; Suitor, Gilligan, Peng, Jung, & Pillemer, 2015; Suitor et al, 2016). This work has largely been framed using social comparison and equity theories to understand the psychological consequences of adult children's perceptions of being over‐ or under‐benefited compared to their siblings as a result of PDT (Peng, Suitor, & Gilligan, 2016; Suitor, Gilligan, Peng, et al, 2015).…”
