Providing the information and guidance clinicians need to understand and assess psychological trauma and its effects, this book presents a step-by-step approach to conducting careful, appropriate, and accurate trauma assessments. From the initial screening, to the selection and administration of more in-depth measures for particular clients, to evaluating results and making a diagnosis, the author helps readers maximize their time and resources and brings much-needed clarity to what can be a confusing and difficult process. Instruments covered include self-report measures and structured interviews of trauma and trauma responses for adults and children. Detailed profiles of 36 measures recommended by the author—many not previously described in the clinical literature, and many available at low or no cost—identify each instrument's suggested uses, special features, format, and psychometric properties, as well as how it can be obtained.
