The changing healthcare environment is creating opportunities for psychologists to practice in non-traditional settings. This paper describes a Veterans Health Administration (VA) initiative to integrate psychologists into its Home Based Primary Care (HBPC) program. As psychologists new to HBPC are learning, the home offers opportunities and challenges not routinely encountered in the traditional office setting. Home-based psychology offers improved access to mental health services, more effective treatment planning, and more accurate assessments in an underserved patient population. Psychologists practicing in this setting also encounter challenges in dealing with patient confidentiality, distractions, role confusion and boundaries, time management, safety, and professional competency. The VA experience is an instructive case example for psychologists considering this growing field of practice. This paper offers lessons learned from this VA initiative and discusses strategies for dealing with potential challenges.
