This edited volume comprehensively examines the critical ethical challenges that arise in the practice of counselling and psychotherapy. It translates philosophical positions and professional ethical guidelines in a way that can be applied to practice. The various chapters focus on specific ethical issues that emerge in working with a range of different client groups; for example, children, couples and families. While some ethical imperatives are common across the board, others could be more closely associated with certain client groups. Practitioners might experience uncertainty in working with vulnerable client groups; for example, lesbian/gay/transgender/intersex (LGBT) clients, or persons who report intimate partner violence. Several chapters raise questions, provide information and additional resources to enhance ethically informed practice. Chapter contributions also highlight the ethical dilemmas that might be unique to certain contexts; for example, private practice, schools and consultation-liaison settings
