“…Grandparental involvement measures also include the frequency of contact between grandparent and grandchild (e.g., Bates & Taylor, 2012, 2016Danielsbacka & Tanskanen, 2016;García-Campos, Aguilar-Zavala, & Malacara, 2010), financial help, and other informal forms of assistance or emotional support (e.g., Fujiwara & Lee, 2008). Also, grandparental well-being has been measured with various variables, such as self-rated health (e.g., Choi & Zhang, 2018;, longevity and time to death (Hilbrand, Coall, Meyer, Gerstorf, & Hertwig 2017a;Hilbrand, Coall, Gerstorf, & Hertwig, 2017b), cognitive functioning (e.g., Ahn & Choi, 2019;Arpino & Bordone, 2014), depression and mental health (e.g., Lee et al, 2019;Xu, 2019), functional limitations/abilities (e.g., O'Loughlin, Loh, & Kendig, 2017;Ku et al, 2012), happiness and life satisfaction (e.g., Danielsbacka & Tanskanen, 2016;Nimrod, 2008), and in many cases, several measurements are utilized in the same study. Among non-coresiding grandparents, most of the results were positive (69%; 51/74).…”
