This review investigates the relevance of socio-cognitive mindfulness (Langer, 1989) to wellbeing coaching by systematically synthesising the evidence to understand how sociocognitive mindfulness interventions work. The search yielded 2,867 peer-reviewed studies with twelve papers meeting the eligibility criteria. The interventions induced socio-cognitive mindfulness with non-clinical adults via one or more psychological processes to achieve intrapersonal, interpersonal and environmental wellbeing. Six of the studies employed exercises to produce boosts in wellbeing, whilst six conducted extended programmes, of which three demonstrated sustained wellbeing improvements. The findings indicate that sociocognitive mindfulness could provide valuable insights for practitioners and synergistic benefits for wellbeing coaching. [ABSTRACT FROM AUTHOR]
