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, Eight-Volume Set focuses on the process of clinical work. Clinical Psychology I: Assessment and Formulation covering the process of assessing clients looking at diagnostics, measures and formulation of presenting problems based on clear theoretical models. Clinical Psychology II: Treatments and Interventions concentrate on treatments and interventions based on the surfeit of clinical, cognitive and neuropsychological models for patient care. Clinical Psychology I: Assessment and Formulation These four volumes cover 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. Clinical Psychology II: Treatments and Interventions These four volumes cover the areas of treatments and interventions. The former targets treatments which are based on a specific theory (for example psychoanalytic, psychodynamic, interpersonal, cognitive, experiential and humanistic) as well as treatment approaches which have been specifically associated with a focused diagnosis (e.g., cognitive therapy for panic disorder). The latter targets interventions which are less specifically associated with diagnostic categories or theoretical models and are often based on features of service settings (for example primary care or forensic settings). These four volumes reflect the diversity of applications of clinical psychology by considering treatments and interventions in adult, children and adolescents, older adults, and families and also cover interventions relating to areas such a neuropsychology (e.g., brain injury).
