The individual interviews were carried out face-to-face in participants’ rooms at each nursing home from March 2015 to October 2015. The data were collected through in-depth semi-structured interviews during a life review program that consisted of six sessions, including childhood, adolescence, young adulthood, older adulthood, summary and evaluation, and integration (Lan et al., 2019). The interview was guided by the topics of a life review form.
