Book excerpt: Essential Skills of Social Work Practice, Third Edition presents the basics of effective social work practice and helps students develop competence in assessment, intervention, and evaluation. Its broad coverage explores the counseling, case management, and research skills necessary to implement evidence-based practice in contemporary social work. Part I of the text includes three chapters that address the core foundations of social work practice: how assessment, intervention and evaluation are linked; the role of theory and research in practice; and a chapter on ethics. Part II, in addition to explaining how to conduct sound assessments and treatment planning, also examines client supportive/engagement skills, cognitive-behavioral skills, and case management skills. Part III focuses on integrating these skills into evidence-based practices with common mental health disorders and problems-in-living with adults, children, and families. Case studies, inspired by real clients, are accompanied by a psychosocial assessment, intervention, and evaluation plan. Appendix B, "The Comprehensive Service Plan," is incorporated throughout the text.
