Free association, dream analysis, resistance, and transference are all aspects of psychodynamic/psychoanalytic therapy. Free association is when a patient talks in a relaxed and aimless way about anything that comes to mind so the therapist can try to determine any thoughts that might be repressed. Dream analysis is when the content of a patient's dreams is analyzed in order to understand the patient's unconscious, especially their wishes. Resistance is when a patient blocks memories from the conscious mind and/or becomes resistant to therapy when the therapist is getting near the heart of why the patient is in therapy. Transference is when the patient begins to react to the therapist in ways influenced by their childhood desires.

Unconditional positive regard is an aspect of person-centered humanistic therapy.

SSRIs, cognitive therapy, group therapy, and person-centered therapy are all treatments for depression; systematic desensitization is a therapy for anxiety disorders, especially phobias.

Social stigma surrounds psychological disorders and their treatment; someone might be afraid of seeming "crazy" if he or she seeks treatment. In addition, some disorders, particularly personality disorders, are characterized by a lack of awareness, so people who have them might not realize they need help. Lastly, people might be overwhelmed at the thought of how/where to start treatment and worried that therapy and medication will be too costly.
