Specifically, it reviews research studies that have used text messages (SMS) or smartphone applications (apps) to improve people’s mental health, psychological well-being, or social relationships. Psychosocial interventions are emerging from the larger and more established mobile health (mHealth) literature of physical health interventions. The scientific knowledge of psychosocial interventions is currently quite limited, with only a few published large randomized control trials. Most of those are limited to North American or European participant samples. The advantages and disadvantages of mobile interventions are discussed, along with recommendations for best practices. The success of future research is dependent upon more researcher-friendly tools to implement interventions.Mobile phonesSocial psychologyTextingSmartphonesHealth interventionsMental healthBook chapter
