Safer and more effective programs are required to cope with an increasing number of older people with depression. Hence, we developed the Positive Photo Appreciation (PPA) program. A three-month pilot randomized controlled trial was conducted with healthy Japanese individuals aged 65–84 years, assigned to a PPA group (n = 28) or Photo Correspondence Education (PCE) (control group) (n = 27). We used the Center for Epidemiologic Studies Depression Scale (CES-D) score as the primary outcome measure. Secondary outcome measures, among others, were cognitive function and positive emotion. Data collected at baseline and post-intervention were analyzed using a linear mixed-effect model. Over 80% of the participants in the PPA group completed and were satisfied with the program. Compared with the PCE group, the CES-D score in the PPA group significantly improved (main effect of group: t = −4.30, p < 0.001; interaction effect of group by time: t = 4.39, p < 0.001), with an effect size of d = 1.23. Additionally, a positive significant interaction effect of group by time was found in the Positive and Negative Affect Schedule (t = −2.33, p = 0.024). The PPA program might be promising for mitigating depressive mood in older adults.
