Therapy
Psychotherapy is an emotionally charged, confiding interaction between a trained therapist and someone suffering from psychological difficulties. The biomedical therapies are prescribed medications or medical procedures that act directly on a patient's nervous system. An eclectic approach to psychotherapy uses techniques from various forms of therapy; psychotherapy integration attempts to combine a selection of assorted techniques into a single, coherent system.
The Psychological Therapies
Psychoanalysis is Sigmund Freud's therapeutic technique of using a patient's free associations, resistances, dreams, and transferences, and therapist's interpretations of them, to help the person release previously repressed feelings and gain insight into current conflicts. Clinicians working from the psychoanalytic perspective try to help people gain insight into the unconscious origin of their disorders, work through the accompanying feelings, and take responsibility for their growth.
Psychoanalysts may ask patients to free associate (saying aloud anything that comes to mind) and watch for pauses or diversions that may indicate resistance (the defensive blocking from consciousness of anxiety-laden material). Analysts may offer patients their interpretation of these instances of resistance, of dreams, and of other behaviors, such as transference (transferring to the therapist the strong feelings harbored against a family member or other significant person). Critics note that traditional psychoanalysis has relied on after-the-fact interpretations and repressed memories, and that it is time-consuming and very costly.
Psychodynamic therapy was influenced by traditional psychoanalysis but is briefer and less expensive. A psychodynamic therapist attempts to focus on and conceptualize a patient's current conflicts and defenses by searching for themes common to many past and present importance relationships, including (but not limited to) childhood experiences and interactions with the therapist. Interpersonal therapy (a brief 12- to 16- session form of psychodynamic therapy) focuses primarily on reliving current symptoms (such as depression) rather than on an intensive interpretation if the origins of unconscious conflicts.
Humanistic therapists focus on clients' present and future experiences, on conscious rather than unconscious thoughts, and on taking responsibility for one's feelings and actions. One of the most famous humanistic therapies was Carl Roger's client-centered therapy. Rogers proposed that therapists' most important contributions are to function as a psychological mirror for the client through active listening, and to provide an environment of unconditional positive regard, characterized by genuineness, acceptance, and empathy. In this growth-fostering environment, Rogers believed, clients would increase their own self-understanding and self-acceptance. \
To help people alleviate current conflict and problems, traditional psychoanalytic therapists attempt to explain the origin of behaviors, and humanistic therapies to promote self-acceptance and self-awareness. Behaviors therapists assume the problem behaviors are the problem, and they attempt to change them through new learning.
Counterconditioning uses classical conditioning techniques to pair new responses with old stimuli that have triggered maladaptive behaviors. Exposure therapies (including systematic desensitization and virtual reality exposure therapy) train people to relax (a response that cannot co-exist with fear) and then to gradually but repeatedly expose them to the things they fear and avoid. Exposure therapies try to substitute a positive response (relaxation) for a negative one (fear). Aversive conditioning uses counterconditioning techniques to pair an unpleasant state with an unwanted behavior. Aversive conditioning tries to substitute a negative response (such as nausea) for a positive one (pleasure) to a harmful stimulus (alcohol).
Operant conditioning therapies are based in the principle that voluntary behaviors are strongly influenced by their consequences. Behavior modification procedures thus enforce desired behaviors and withhold reinforcement for, or punish, undesired behaviors. Therapists sometime create token economics, in which people receive tokens for a privilege or treat. Critics object (1) on the practical grounds that these behaviors may disappear when the tokens are discontinued, and (2) on the ethical grounds that it is not right to control other people's behavior. Proponents counter with the arguments that (1) social or intrinsic rewards can replace the tokens and continue to be reinforcing, and (2) reinforcing adaptive behavior is justified because, with or without behavior modification, rewards and punishers will always control people's behavior.
Cognitive therapy attempts to teach people to think in more adaptive ways, on the assumption that thoughts intervene between an event and our emotional reactions to it. Cognitive behavior therapy attempts to teach people to think in more adaptive ways but also to practice their new ways of thinking in everyday life. In Aaron Beck's cognitive therapy for depression, therapists try to change self-defeating thinking by training clients to look at themselves in new, more positive ways. In stress inoculation training, another form of cognitive therapy, people with depression learn to dispute their negative thoughts and to restructure their thinking in stressful situations. Depressed people also work to establish to attribution style of nondepressed people (taking credit for good events and not taking blame for, or overgeneralized from, bad events).
In groups normally consisting of 6 to 9 people, therapists may be less involved with each member, but the (on average) 90-minute session can help more people and cost less per person than individual therapy would. Clients may benefit from knowing other have similar problems and from getting feedback and reassurance. Most forms of therapy can be adapted to a group setting. Family therapy views a family as an interactive system and attempts to help members discover the roles they play and to learn to communicate more openly and directly. Millions of people participate in self-help and support groups, such as Alcoholics Anonymous.
Evaluating Psychotherapies
Clients judge psychotherapy to be effective for three reason: They tend to enter therapy in crisis, they need to believe their time and expenses justified, and they try to find something positive to say when asked to evaluate their therapist. But research has not generally upheld clients' estimates of therapy's effectiveness.
Clients enter therapy when they are unhappy, leave it when they are less unhappy, and stay in touch only if satisfied with the treatment they received. So clinicians are mostly aware of other therapists' failures, not their own. Both the placebo effect (the belief a treatment will work) and regression toward the mean (the tendency for extreme or unusual scores to fall back toward the mean) contribute to clients' and clinicians' misperceptions of the effectiveness of psychotherapy.
Outcome studies are randomized clinical trials in which people on a waiting lists receive therapy or no therapy. Statistical digests (meta-analyses) of hundreds of these studies reveal that (1) people who remain untreated often improve, but (2) those who receive psychotherapy are more likely to improve, and (3) people who receive psychological treatment spend less time and money later seeking other medical treatment, compared with their counterparts and waiting lists.
Meta-analyses indicate that no one type of therapy is most effective overall, nor is there any connection between effectiveness and a therapist's training, experience, supervision, or licensing. Some therapies are particularly well-suited to specific disorders, such as cognitive, interpersonal, and behavior therapies for depression; cognitive, exposure, and stress-inoculation therapies for anxiety; cognitive-behavior therapy for bulimia; behavior modification for bed wetting; and behavior conditioning therapies for phobias, compulsions, and sexual disorders. The more specific the problem, the greater the chances for effective treatment. Debate continues over the extent to which clinical practice should be based on scientific evidence or intuitive responses.
In EMDR therapy, a therapist attempts to unlock and reprocess previously frozen traumatic memories by waving a finger in front of the eyes of a person imagining traumatic scenes. EMDR has not held up under scientific testing, and its modest successes may be attributable to the placebo effect. In people with seasonable affective disorder, a form of depression linked to periods of decreased sunlight, light exposure therapy (exposure to daily timed doses of light that mimics outdoor light) has been proven effective by scientific research.
All types of psychotherapy seem to offer new hope for demoralized people, a fresh perspective, and an empathetic, trusting, caring relationship. The therapeutic alliance – the emotional bond between therapist and client – is an important part of effective therapy and may help explain why some paraprofessionals can be as helpful as professional psychotherapists.
Psychotherapists may differ from each other and from clients in personal beliefs, values, and cultural background. Such differences can be affect the formation of a bond between therapist and client. People searching for a therapist should have preliminary consultations with two or three to gain an understanding of the therapists' values, credentials, and fees, and to find someone with whom they feel comfortable.
The Biomedical Therapies
Psychopharmacology is the study of drugs effects on mind and behavior. Since the 1950s, drug therapy has been used extensively to treat psychological disorders. Double-blind studies, in which neither the medical staff nor the patient knows whether the patient is taking the real drug or a placebo, eliminate the bias that can result from Clinicians' and patients' expectations of improvement.
The antipsychotic drugs dampen responsiveness to irrelevant stimuli, and they have been used effectively to treat schizophrenia accompanied by positive symptoms (the presence of hallucinations and delusions). Dosage varies from person to person. The first-generation antipsychotic drugs, which block D2 (dopamine) receptors, can produce tardive dyskinesia, (involuntary movements of facial muscles, the tongue, and arms and legs). The second-generation of antipsychotics, which target D1 receptors, can affect metabolism, increasing the risk of obesity and diabetes.
The antianxiety drugs depress central nervous system activity. They are often used in combination with psychotherapy for treatment of anxiety disorders. Antianxiety drugs can be psychologically and physically addictive.
Antidepressant drugs increase the availability of norepinephrine or serotonin, which elevate arousal and mood. Antidepressant like Prozac, which block the reuptake of serotonin, are known as selective-serotonin-reuptake-inhibitors (SSRIs). Dual-action antidepressant block the reuptake or absorption of both norepinephrine and serotonin, but they have a greater risk of side effects. Antidepressants are used to treat depression (often in combination with cognitive therapy) and the anxiety disorders. Antidepressants begin to influence neurotransmitter system almost immediately, but their full psychological effects may not appear until weeks later. The suicide risk for those taking these drugs may have been overestimated.
A few drugs, such as lithium for bipolar disorder, have proven very effective in stabilizing moods. Researchers do not yet understand how these medications work.
ECT is a biomedical therapy in which a brief electric current is sent through the brain if an anesthetized patient. Although controversial, ECT remains an effective, last-resort treatment for many people with severe depression (it is ineffective in treating other disorders) who have not responded to drug therapy. How ECT works is unknown. Depression has also been alleviate by some implanted devices that stimulate parts of the brain or the vagus nerve sending signals to the limbic system. Following early reports of success, large clinical trials are under way to study repetitive transcranial magnetic stimulation (rTMS). In this painless procedure, pulses of magnetic energy sent through the skull to the surface of the cortex stimulate or dampen activity in various areas of the brain.
Lobotomy was a crude procedure in which surgical instruments inserted through a patient's eye sockets were used to sever connections running to the frontal lobes of the brain. The intent was to calm uncontrollably emotional or violent patients, but instead it usually created lethargy and an impulsive personality. This surgery disappeared in the 1050s, when its harmful effects became known and new and effective drug treatments were introduced. Today, neurosurgeons rarely perform brain surgery to treat psychological disorders. Even when MRI-guided precision surgery is considered for exceptional, life-threatening conditions, it is a treatment of last resort because its effects are irreversible.
Preventing Psychological Disorder
Advocates of preventive mental health argue that many psychological disorder could be prevented. Their aim is to change oppressive, esteem-destroying environments into more benevolent, nurturing environments that foster individual growth and self-confidence.
