Smartphones can aid in making psychotherapy available to the many individuals who do not otherwise have access to empirically supported treatments for their psychological disorders. Smartphones combine the capabilities of traditional computer devices with telecommunication technologies including programmability, storage capacity, and wireless communication and networking capabilities. An important benefit provided by smartphones is the ability to conduct ecological momentary interventions (EMIs) with computer applications that more effectively integrate psychotherapy interventions into the daily lives of patients. With smartphone-based EMI applications, smartphones make it easier to collect data from patients as they practice new behaviors and skills within their natural environment and to assess patient progress and application usage on a daily basis (a clinical and research methodology known as ecological momentary assessment, or EMA). The author reports results from a multi-case study of the use of a smartphone application for the treatment of depression. Theoretically relevant rationales for using smartphones in the treatment of depression are enumerated, results of the present study are discussed, and suggestions for future research are presented.
