The American Psychological Association (APA) is a professional organization that focuses on advancing psychology as a science and profession. Founded in 1892, it provides resources for researchers, educators, and practitioners. One of its key contributions is the APA Style, a set of guidelines for writing and citing sources in academic papers, which helps ensure clarity and consistency in scholarly communication. APA also publishes a variety of journals and books that share research findings and promote best practices in psychology. By setting ethical standards and providing educational resources, the APA plays a crucial role in shaping the field of psychology and supporting mental health professionals.
