A quality review of smartphone applications for the management of pain.

Smartphone applications (apps) are recent innovations that have not been studied extensively. The lack of regulatory body assessing the content of existing apps means that their quality is often unknown. This review aims to assess the quality of smartphone apps that claim to provide information and treatment for pain conditions. It assesses the degree to which apps adhere to evidence-based practices in psychological research for pain management and which stand the best chance of being effective for consumers. Another aim is to identify potential apps health-care professionals may wish to recommend to clients. Pain management apps on the official iPhone and Android stores were searched in January 2014. Those containing a psychological component in the app description were downloaded and rated for quality using a checklist devised by two researchers. The checklist was based on cognitive behavioural therapy (CBT) guidelines since the latter is the most effective intervention for computerized programs. A total of 195 apps met inclusion criteria. Although CBT is a promising alternative to traditional psychological interventions, only six apps endorsed theoretical reference to CBT principles. Existing apps are often constructed by lay people or software developers, with little input from health-care professionals. Pain apps sometimes promise a solution to pain without a consideration of app content. The development of evidence-based apps and rigorous evaluation of any long-term outcomes are important in enhancing understanding of the potential of these apps.
