Which of the following best describes the role of psychological services?

The role of psychological services primarily revolves around providing therapy for mental health issues. This is fundamental to the practice of psychology, where trained professionals work directly with individuals, groups, or families to address emotional, psychological, and social challenges. The therapeutic process often involves various modalities, such as cognitive-behavioral therapy, psychodynamic therapy, or humanistic approaches, all aimed at improving mental health outcomes and enhancing the quality of life for clients.

While researching cognitive development, teaching psychological theories, and writing psychological assessments are important aspects of the wider field of psychology, they do not fully encompass the core of psychological services. These activities might contribute to the field at large or support clinical practice, but the primary mission of psychological services is to directly facilitate healing and growth through therapy, making option B the most accurate representation of the role.
