According to the American Psychological Association, in psychotherapy, therapists help people of all ages live happier, healthier, and more productive lives. Therapists apply research-based techniques to help people develop more effective habits. There are several approaches to psychotherapy, including cognitive-behavioral, interpersonal, and psychodynamic, among others, that help people work through their problems. Psychotherapy is a collaborative treatment based on the relationship between an individual and a therapist. Therapists provide a supportive environment that allows you to talk openly with someone who is objective, neutral, and nonjudgmental. Most therapy focuses on individuals, although therapists also work with couples, families, and groups.
