In the UK, Community pharmacies have been recognised as being easily accessible and positive settings to implement public health interventions [1,2]. This submission aims to present the findings from ‘Prescribing Happiness’ (P-Hap) a PPI implemented and evaluated in a community pharmacy in Wales. The Medical Research Council (MRC) framework for complex interventions underpinned the basis of the study design [3,4]. The MRC framework is composed of four phases; (1) Development, (2) Feasibility and Piloting, (3) Evaluation and (4) Implementation. Phases 1 and 2 were completed earlier in this programme of work which resulted in the development of P-Hap, a six-week one-to-one PPI underpinned by PERMA [5]. P-Hap was delivered to community members (n=21) who were recruited via email, posters or word of mouth. A mixed methods evaluation was conducted to compare baseline (T1), post-intervention (T2) and two-weeks post-intervention (T3) utilising satisfaction with life (SWLS) and subjective happiness (SHS) measurements. One-way repeated ANOVAs were run to measure the effect of time on wellbeing and happiness. A semi-structured interview was conducted at T3 to capture participants’ perspectives on the intervention. Interviews were audio-recorded and analysed using thematic analysis. Results revealed that for SHS, there was an effect of Time (F1.338,10= 15.7, p=.001), where post hoc analyses using a Bonferroni correction showed that scores T3 were higher than scores at T1 (p=.003). For SWLS, there was an effect of Time (F1. 148, 15.0= 29.002, p=.000), where post hoc analyses using a Bonferroni correction showed that scores Time 3 were higher than scores at Time 1 (p=.000). Four main themes emerged from the findings, (1) Physical Factors supporting engagement, (2) Phases of Psychological Engagement, (3) Wellbeing Facilitator Delivery Role and (4) Impact of the Course, with sub-themes. This talk will discuss the results and their implications for community and wider PPI research.
