Major developments which may influence this include the increasing use of online and mobile technology as media for delivering interventions, increasing employment of graduate level mental health workers, and an increasing role of peers with lived experience in provision of services. These developments each demand the availability of simpler, or lower intensity, intervention models, which may benefit from the development of simple focused intervention methods aligned with particular therapeutic targets and processes (see Hayward et al107 for an example of a self-help intervention).
