Guideline to address problem gambling in Australia and provide recommendations to guide practice, patient and policy decisions for screening, assessment and treatment of problem gambling. Summarises the research and the current state of knowledge, based on evidence up to March 2010. Makes several recommendations for practice where sufficient high quality evidence is available. There are three categories of recommendations: evidence-based, consensus-based, and practice points. There are seven evidence-based recommendations, all of which relate to treatment. Each recommendation is associated with a Grade which indicates the level and quality of evidence upon which it is based. Each recommendation should be read in conjunction with practice points. For screening and assessment, in the absence of sufficient high quality evidence, there are three consensus-based recommendations and three practice points.
