Abstract – Introduction

Few guidelines exist on how to conduct Phase 1 feasibility studies in psychological therapies. It may be theoretically argued that small-size feasibility studies are best studied with mixed methods. The primary aim of this study was to examine the feasibility of using mixed methods in feasibility studies. The secondary aim was to systematically explore the feasibility of a 16-session treatment manual in transactional analysis psychotherapy (TAP) for depression developed in a prior Phase 0 study.
