Practice and training norms and recommended minimum standards are available internationally for MBSR and MBCT. However, they are not available for delivering non-eight-week mindfulness-based interventions (MBIs) adapted for specific contexts and populations. The delivery of these MBIs raises dilemmas for organisations with responsibility for safe and effective practice that invites us to steer a middle course between prohibition and permissiveness and between idealism and pragmatism. One response to practitioners delivering adapted MBIs is discussed with reference to a new briefer but specifically tailored training for those delivering adapted MBIs in a UK government-funded health service.
