A number of necessary lessons can be learned from this well-crafted, scholarly, and internationally oriented text. The book is an around-the-world tour of mental health measurement in fewer than 300 pages. Your journey takes you through three well edited sections: Outcome Measurement Around the World, Outcome Measurement in Specific Groups and Settings, and Current Issues in Outcome Measurement. First, by examining mental health assessment in the United Kingdom and other European countries and in Australia and New Zealand, and by even taking a glimpse at assessment in the United States, we see a reassuring picture of responsible academics, clinicians, and governments making their mental health programs work as cost-effectively as possible. There is even significant agreement among domains to focus upon and measure.
