Mohammad Khudair's dataset contains results from a positive mood induction intervention study involving 115 older adults. Participants were exposed to 15 minutes of audiovisual stimuli daily for seven consecutive days, with mood and depressive symptoms measured pre- and post-intervention. The data, last updated in 2026, shows consistent significant improvements in outcomes, with effects moderated by baseline depressive symptoms.
