This study is concerned with evaluating an innovative care delivery platform that is becoming widely available but has not been adequately evaluated in a clinical trial. Primarily, this study is concerned with whether text based care is clinically effective, and if that effect is a function of (1) intervention intensity, (2) timeliness and match of therapeutic recommendations and (3) more stable mood and function over time. Based on the existing, yet limited data in the field, there is evidence to suggest that more frequent encounters with a psychotherapist results in better treatment adherence and faster and more stable response to treatment.

Mobile psychotherapies have been shown to be reliable and effective platforms for delivering evidence-based psychotherapies, and have the potential to reach millions of lives. Several recent randomized clinical trials demonstrate that mobile psychotherapy is effective for mild to moderate depression. These studies also demonstrate that mobile psychotherapy overcomes transportation, time, and stigma barriers for minority and rural individuals. These interventions are found to be culturally relevant and avoid the stigma concerns faced by many minorities and immigrant populations and improve access for those who are too physically disabled to leave home for in-person treatment. Available platforms range from fully self-guided treatment, text-based care, and telephone based psychotherapy. Although self-guided care may be the most cost efficient method of care, recent research shows that this is a highly under-utilized form of care and in soon to be released publication from our group, most patients find this a less appealing form of treatment because of the lack of accountability of the treatment and motivational issues that are a consequence of these illnesses. Indeed, other work suggests that consumer internal resources such as motivation fatigue and illness burden impact engagement with self-guided treatment. Although there is a population to which self-guided treatment may be appealing, in the broader context, access to a coach or expert is needed for these to be effective models of care.

Text-based care however is becoming a widely popular and available form of psychotherapy delivery. Part of the appeal of text-based care is that consumers can access care when they need and at their convenience, and may be able to have more frequent contact with their therapists over the course of treatment. Telephone based psychotherapy is a well-established form of psychotherapy delivery, with several meta-analyses demonstrating not only clinical equivalency with face-to-face psychotherapy, but better adherence to treatment. However, most telephone-based psychotherapy is delivered in a traditional manner, with one-hour, weekly appointments. Although this is an effective manner of care, it still requires that consumers set aside time during the week to receive care and does not allow for in-the-moment care.

Conceptually, text-based care has many potential therapeutic advantages over traditionally delivered telephone-based care. This model of care is similar to Ecological Momentary Intervention (EMI). This intervention model is based on the theory that interventions have their biggest clinical impact when the consumer is at their greatest level of receptivity, and through better timing and tailoring, improve the consumer's readiness to change, self-efficacy to implement the intervention and great behavioral activation in goal directed behavior.
