In Study 1, Bryant and colleagues (2005) recruited 180 college students. Participants completed surveys that included a measure of happiness (the outcome variable) as well as a scale to measure ability to positively recall past experiences on a 1-7 scale. Participants were also asked how much they reminisced.

Results of the study indicated that the more college students reported reminiscing about positive past experiences, the higher their happiness levels, r = .27, p <.001.
