Participants reported on measures of subjective well-being (life satisfaction and felt emotion) before and for 14 weeks after attendance. Repeated measures analysis demonstrates that participants significantly improved in all measures following attendance at the seminar (p < .03), with medium-to-large effect size (.5 < d < 1.2). Contrast analysis showed that participants maintained their subjective well-being throughout the follow-up period (p < .01). The report details possible group and individual mechanisms of change that may be utilized by the seminar to increase well-being. It also explores ways to minimize risk of psychological harm to participants.positive psychologypositive interventionsexperientialemotionpositiveinterventionswell-beingsatisfactionpositive emotionsatisfaction with life scalelife satisfactionCognitive PsychologyHealth PsychologyOther PsychologySocial PsychologyDissertation/Thesis
