1. PhD Scholarship available: Understanding the barriers and facilitators of delivering a technology-assisted telehealth psychotherapy intervention to people with dementia
As part of the study, we will undertake a process evaluation to assess treatment fidelity, dose and contextual factors that may influence effectiveness, to inform future implementation in community and memory clinic settings. The PhD project will focus on developing the future implementation framework for Tech-CBT. This project would suit someone with a background in psychology or health sciences.
