Theoretical perspectives in the study of human behavior can be easily applied to cases in social work practice. The field of mental health in particular lends itself to the application of various theories of human behavior. Specifically, depression can be viewed through the lens of social cognitive theory or social cognitive learning. There is a case of a depressed woman, whose name will be changed, to whom social cognitive theory can be applied. Cheryl is a 58-year-old woman diagnosed with major depressive disorder. He has had this diagnosis since he was 17 years old. Many of his symptoms and experiences can be viewed or explained in terms of social cognitive theory. Social cognitive theory is different from social learning theory because it takes into account cognitive processes including thinking, memory, language, and evaluation of consequences. According to social cognitive theory, individuals play a role in their development (Malone, 2002). Cognitive models play a very important role in depression (Furman & Bender, 2003). For example, people don't have the motivation to keep going during difficult times if they don't believe they can. Self-efficacy is an important part of personal action and a major aspect in social cognitive theory (Bandura, 2001). A person's perceived abilities and confidence play a role in what they do in their life. According to social cognitive theory, cognition becomes a motivator or an obstacle. A person's perceived self-efficacy helps determine what they choose to do, how much effort they put in, and how long they can persist if barriers or failures occur. How a person views failure is also influential (Bandura, 20... half of article... Bandura, A. (2001). Social Cognitive Theory: An Agentic Perspective.
