ABSTRACT
Introduction Skilled psychological practitioners need to be able to develop evidence-based preventative, developmental, and remedial interventions and services. Interventions and services require linking to the diagnosis of and case formulation for the client, or clients, involved. Psychologists furthermore need to evaluate the impact of the services they provide, which will necessitate ongoing monitoring, evaluation, and effectiveness review. Psychologists thus need to know how to measure change in behavioural, cognitive, and emotional functioning. Treatment knowledge involving individuals, couples, families, groups, and wider organisational or community interventions relating to mental health problems as well as positive well-being and organisational effectiveness is necessary (Psychology Board of Australia, 2012). Psychologists are aware of contextual influences on intervention and basic psychopharmacology as their clients will come from various contexts and many will have taken medications or other substances. In this chapter, both psychological and psychopharmacological interventions are reviewed.
