With its timely focus on aging-related applications of cognitive-behavioral therapy (CBT), this book offers flexible tools and evidence-based strategies for use with middle-aged and older adults. Stand-alone chapters make it easy to flip between topics and tailor CBT to each client's needs, strengths, and circumstances. The book dispels ageist misconceptions while exploring assessment and treatment of common challenges, including depression, anxiety, loneliness, complicated grief, chronic pain, sleep problems, brain health concerns, and more. Sample dialogues, “Did You Know?,” and “Examining Our Attitudes” boxes help clinicians build and apply key skills. Detailed examples of best practices will be appreciated by providers across a range of clinical settings. The companion website provides downloadable handouts and other helpful resources.
