Technologies such as smartphones and digital cameras are an increasingly ubiquitous part of modern life, and the increasing convenience of these electronic tools provides psychotherapists with opportunities to incorporate these technologies into psychotherapy. In the face of so much opportunity, psychotherapists must learn how to incorporate these tools effectively and responsibly. The authors present three case studies that demonstrate the use of digital technology to individualize and enhance the efficiency of existing evidence-based treatments. In the first, digital pictures were used to track the treatment progress of a client who compulsively hoards. In the second, a smartphone was used to record a personalized progressive muscle relaxation file for a client with agoraphobia, hypochondriasis, and generalized anxiety disorder. In the third, a smartphone was used to photograph and send pictures of in-session work to a client with trichotillomania and generalized anxiety disorder. The implications and ethical considerations of using technology in psychotherapeutic settings are explored, and practical strategies are provided for incorporating common digital technology into psychotherapeutic practice.
