Verified step by step guidance

1. Step 1: Understand the treatments mentioned for OCD: Psychoanalysis, Cognitive-Behavioral Therapy (CBT) with exposure and response prevention, and Selective Serotonin Reuptake Inhibitors (SSRIs).
2. Step 2: Review current research evidence on the effectiveness of these treatments. CBT with exposure and response prevention is widely supported as the most effective treatment for OCD.
3. Step 3: Recognize that SSRIs, a class of antidepressant medications, are also effective but generally considered less effective than CBT with exposure and response prevention.
4. Step 4: Note that psychoanalysis, a traditional form of therapy focusing on unconscious conflicts, has little empirical support for treating OCD and is considered the least effective among the three.
5. Step 5: Based on this understanding, arrange the treatments from most to least effective as: CBT with exposure and response prevention, SSRIs, and then psychoanalysis.
