We see therefore that the school environment provides not only a convenient location for promoting the wellbeing of children and adolescent’s, but it also provides an appropriate atmosphere to foster aspects of PP which are significant to well-being in youths, such as providing the arena for developing ‘interests’. It also provides improvements in mental health conditions and apparently maintained improvements as shown in longitudinal data. Limitations of these studies are that none of the data comes from younger children and so it is uncertain
whether we can transpose findings in introducing PP interventions to improve well-being in general, on a younger age group. Conversely evidence of similar interventions is currently being administered in the U.S. to younger children of middle school age; The Penn Resiliency Program aims to promote resiliency and well-being through PP, and has been administered to this younger group (Kranzler, Parks, & Gillham, 2011). However, Kranzler, Parks, and Gillham’s study focuses on the strengths and weaknesses of the undergraduate course to conduct such research, rather than data of efficacy. This paper brings to the fore an important consideration about the degree of training required to administer interventions, making a large-scale SB programme less feasible without prior extensive research.
