Depression is a leading mental health concern in aging individuals. Written to be used in collaboration with a qualified mental health professional, <em>Treating Later-Life Depression: Workbook</em> is designed to address and alleviate depression and related concerns (chronic pain, sleep problems, anxiety, brain health, family caregiving and grief) in middle-aged and older adults. This practical <em>Workbook</em>, along with its companion <em>Clinician Guide</em>, reflects the latest scientific and clinical advances in cognitive-behavioral therapy for age-related problems, in individual, group, and telehealth formats. Along with learning how to re-engage in a meaningful daily life, individuals will build skills using personalized change strategies such as problem solving, relaxation training, self-compassion, reframing unhelpful thoughts and effective communication practices, among others. The <em>Workbook</em> closes with resources to support middle-aged and older adults' ongoing efforts at achieving and maintaining a greater sense of wellbeing.
