Abstract
A mathematical model is applied to happiness and mood data from a successful group therapy intervention with elderly nursing home residents (Rattenbury and Stones, 1989). The model permits estimations of acute environmental change within and across therapy sessions, and the comparison of such estimates with the changes in happiness from before to after the total intervention. The findings show intervention success (i.e., the change in happiness) to correlate with across session changes, and particularly those in the basal (presession) acute environment, but with no correlation between therapeutic success and within session changes. These findings suggest a positive facilitation to the chronic environment during the progression of therapy.
