Objectives. There is growing support within the therapy professions for using talking therapy in alternative environments, such as outdoor spaces. The aim of the present study was to further understand how the organizational culture in clinical psychology may prevent or enable practitioners to step outside the conventional indoor consulting room.Design. Informed grounded theory methodology was used within a pragmatist philosophy.Methods. Participants (N = 15; nine male, six female) were identified using theoretical sampling. The sample consisted of experts and leaders within the profession of clinical psychology (e.g., heads of services, training programme directors, chairs of professional bodies, and developers of therapy models; M years in the profession = 34.80, SD = 9.77). One-to-one interviews and analysis ran concurrently over 9 months (April-December 2020). Mason's model of safe uncertainty was drawn upon to illuminate and organize themes.Results. The main themes comprised organizational factors that either support a practitioner in maintaining a position of curiosity and flexibility towards the environment where therapy is located ('environmental safe uncertainty'), or push them towards adopting a more fixed position ('environmental certainty'). Themes included influences from therapy traditions, accessibility of alternative environments, internalized risk, workplace subcultures, business models, biomedical approaches, and the COVID-19 pandemic.Conclusions. Whether therapy is located in a consulting room, outdoors, clients' homes, or digitally, practitioners, clients, and services are encouraged to maintain a position of environmental safe uncertainty.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
