In the context of evidence-based practices, which of the following treatments would be most effective in treating depression, developmental disabilities, and bed-wetting?

A) exorcism
B) behavior therapy
C) exposure treatment
D) modeling

Behavior therapy has been widely recognized as an effective evidence-based practice for a range of mental health concerns, including depression, developmental disabilities, and bed-wetting. This approach is based on the principles of learning theory and focuses on identifying and modifying maladaptive behaviors through various techniques, such as positive reinforcement, shaping, and extinction. It has been found to be more effective than other treatments, such as exorcism or exposure treatment, which may lack empirical support or may not address the underlying behavioral mechanisms. Modeling, while also a useful technique in behavior therapy, may not be sufficient for addressing the complexities of these specific conditions.
