Clinical psychology is a vast area of research, on an international stage, fundamentally addressing psychological problems or disorders from an assessment, diagnostic and interventionist point of view. This complex field of science studies a mix of complex client groups (children to the elderly) and a variety of different perspectives of study (from neuropsychology to psychotherapy perspectives). Clinical Psychology I: Assessment and Formulation covers the areas of assessment of presenting problems within the field of clinical psychology (including diagnosis, testing, interpretation, psychometrics, instruments, measures and clinical significance), and the formulation of presenting problems within particular theoretical models (such as psychodynamic models - attachment theory; cognitive models of diagnostic presentations; case formulation approach). The combination of these two key terms provides the necessary base for highlighting the range and sophistication of psychological approaches to these areas allowing a focus on the traditional 'diagnostic' approach but also a wider and more diverse approach beyond diagnosis. Accordingly, these four volumes capture a breadth of psychological theory that would otherwise be lost.
