Chapter 16: Psychological and Biological Treatments Helping People Change Copyright © Allyn & Bacon 2009 Lecture Preview Identify who seeks psychotherapy and who benefits from it Describe and evaluate the effectiveness of insight therapies and behavioral therapies Explore group and family therapies Discuss whether psychotherapy is effective Identify biological treatments for psychological problems Copyright © Allyn & Bacon 2009 Psychotherapy Who goes to therapy? Who practices therapy? Women are more likely than men Caucasian Americans are more likely than Asian Americans and Hispanic Americans Clinical psychologists, psychiatrists, mental health counselors, clinical social workers, paraprofessionals Who benefits most from therapy? Patients with some anxiety often do better Patients who are better adjusted to begin with Copyright © Allyn & Bacon 2009 Psychoanalysis: The First Therapy Sigmund Freud – believed abnormal behavior was caused by unconscious feelings, thus the goal of psychotherapy was to make conscious these unconscious feelings Six primary approaches: Free association – patients express themselves without censorship Interpretation – therapists formulate explanations from the free association Dream analysis – dreams express unconscious feelings, the therapist can interpret these Copyright © Allyn & Bacon 2009 Psychoanalysis: The First Therapy Freud’s six primary approaches (cont.): Resistance – attempts to avoid confrontation and anxiety associated with uncovering previously repressed thoughts, emotions, and impulses Transference – projecting intense, unrealistic feelings and expectations from the past onto the therapist Working through – confronting and resolving problems, conflicts, and ineffective coping responses in everyday life Copyright © Allyn & Bacon 2009 Neo-Freudian Psychoanalysis Followers of Freud consider conscious, cultural, and interpersonal influences on behavior, along with adopting a more positive approach. Jung’s Analytic Psychology – focused on individuation, the integration of opposing aspects of the patients personality Amplification – patients and therapists expand on dream associations Prognostic dreams – dreams that foretell the future Copyright © Allyn & Bacon 2009 Neo-Freudian Psychoanalysis Object relations therapists – emphasize patients’ mental representations of themselves and others Focus on patients’ difficulties with trust, attachment, separation, identity formation Interpersonal therapy – short-term treatment that strengthens socials skills and targets interpersonal problems, conflicts, and life transitions Copyright © Allyn & Bacon 2009 Critical Analysis of Psychodynamic Therapies Many treatments are not scientifically sound: Poor external validity – Freud and Jung had a limited population of wealthy, intelligent, successful people Clinical sessions were never systematically examined and thus could not be replicated Relied heavily on memories from the patient’s past, yet recent evidence has called into question the validity of these memories Not falsifiable - unable to disprove rival hypotheses Research has shown that brief treatments are better than none, however, they do not work as well as other therapies (e.g., cognitive behavioral therapy) Copyright © Allyn & Bacon 2009 Apply Your Thinking What were some of the consequences of psychoanalytical methods that attempted to bring out repressed memories? There is little evidence for the existence of repressed memories and the consequences can be far-reaching. A number of patients have “remembered” past sexual abuse and attributed them as the cause of their problems, only to find out that these memories were not real. This is dangerous, as it has sent a number of people to jail, and it does not treat the actual cause of the mental illness. Copyright © Allyn & Bacon 2009 Humanistic-Existential Psychotherapy Therapies that share an emphasis on the development of human potential and the belief that human nature is basically good Humanistic – self-actualization occurs naturally, unless roadblocks hamper it Existential – struggle, pain, and self-discipline inevitably occur along the road to personal fulfillment Both utilize a phenomenological approach – therapists encounter patients in terms of the subjective phenomena (thoughts, feelings) they experience in the present Copyright © Allyn & Bacon 2009 Humanistic-Existential Psychotherapy Person-centered therapy – centered on the patient’s goals and ways of solving problems Carl Rogers Therapists don’t tell the patient how to solve their problems, and patients can use their time however they choose Therapists exhibit unconditional positive regard to elicit a more positive self-concept Copyright © Allyn & Bacon 2009 Humanistic-Existential Psychotherapy Gestalt therapy – aims to integrate different, and sometimes opposing aspects of personality, into a unified sense of self Two-chair technique to promote self-awareness Considered an experiential therapy because it recognizes the importance of awareness, acceptance, and expression of feelings Copyright © Allyn & Bacon 2009 Humanistic-Existential Psychotherapy Logotherapy – therapeutic approach that helps people find meaning in their lives Victor Frankl – believed that humans can preserve freedom of mind through even the worst conditions imaginable Discourages patients from blaming past circumstances, other people, and adverse situations for their difficulties Copyright © Allyn & Bacon 2009 Critical Evaluation of HumanisticExistential Therapies Difficult to falsify Like Roger suggested, therapeutic relationship does appear to be a strong predictor of therapeutic success Empathy and positive regard are moderately correlated to therapeutic success However, most research comes from clinical anecdotes and case studies Ultimately, these therapies are generally successful, however there is disagreement on the level of success Copyright © Allyn & Bacon 2009 Behavioral Approaches Behavioral therapy – focuses on specific problem behaviors, and current variables that maintain problematic thoughts, feelings, and behaviors Seeks to identify and assess the problem, then design and implement a strategy for behavior change Exposure therapy – confronts patients with their fears, with the goal of reducing that fear Systematic desensitization – patients are taught to relax as they are gradually exposed to what they fear, in a stepwise manner Flooding – patients immediately experience their greatest fear, with no aversive consequences Copyright © Allyn & Bacon 2009 Flooding Based on the idea that fears are maintained by avoidance (negative reinforcement) Flooding provokes anxiety in the absence of negative consequences, so that extinction can proceed Response prevention is critical - therapists prevent patients from performing their typical avoidance behaviors Can be done with virtual reality Copyright © Allyn & Bacon 2009 Dismantling Desensitization Dismantling – research procedure for examining the effectiveness of isolated components of a larger treatment Dismantling studies show that each component of desensitization (relaxation, imagery, anxiety hierarchy) can be eliminated without affecting the treatment Placebo effect or extinction of fear? Copyright © Allyn & Bacon 2009 True or False? Misuse of a flooding procedure can actually lead to increased fear. TRUE. If flooding is not done for long enough there can be negative consequences. The exposure to the fearful stimulus must be sufficient, and without negative consequences. Any negative reaction the patient experiences may be enough to worsen their fear. Copyright © Allyn & Bacon 2009 Behavioral Approaches Participant modeling – therapist first models a problematic situation, and then guides the patient through steps to cope with it unassisted Important component of assertion training and behavioral rehearsal Operant procedures – using reward and punishment to shape behavior Token economy – desirable behaviors are rewarded with tokens that patients can exchange for tangible rewards Aversion therapy – uses punishment to decrease the frequency of undesirable behaviors Copyright © Allyn & Bacon 2009 Behavioral Approaches Cognitive-behavior therapy – attempts to replace maladaptive or irrational cognitions with more adaptive, rational ones Core assumptions: Cognitions can be identified and measured Cognitions are the key player in both healthy and unhealthy psychological functioning Irrational beliefs can be replaced by more rational and adaptive cognitions At least as effective as psychodynamic, personcentered, or drug therapies Can be effectively combined with drug therapies or marital counseling Copyright © Allyn & Bacon 2009 Group Therapies About as effective as individual treatment for most problems Internet self-help groups have recently surged and can be effective Alcoholics Anonymous is a Twelve-Step, self-help program that provides social support for achieving sobriety • Research indicates this program is about as effective as cognitive-behavioral therapy, however the sample may not be representative of the entire alcoholic population, since 68% of participants drop out within 3 months Copyright © Allyn & Bacon 2009 Apply Your Thinking How might high dropout rates distort the findings of studies that examine the success of AA? Random selection is compromised when there is a high dropout rate. People who drop out of AA may do so because they are unsatisfied with the progress they are making. The remaining 32% may be the ones that are doing well in the program. However, they are not a representative sample of the alcoholic population and the results may have low external validity. Copyright © Allyn & Bacon 2009 Family Therapy Strategic family intervention – family therapy approach designed to remove barriers to effective communication Structural family therapy – treatment in which therapists deeply involve themselves in family activities to change the structure of interactions Copyright © Allyn & Bacon 2009 Is Psychotherapy Effective? Dodo bird verdict – some researchers believe that all treatments are equal and effective May be due to common factors between therapies Many others are not convinced Behavioral and cognitive-behavior therapies are often more effective in many domains Some therapies can have negative effects: • Facilitated communication, Scared Straight programs, recovered-memory techniques, dissociative identity disorderoriented psychotherapy Different groups may respond differently Copyright © Allyn & Bacon 2009 Is Psychotherapy Effective? Empirically supported therapies (ESTs) – treatments for specific disorders supported by high-quality scientific evidence • Many therapies are not supported by empirical data • A treatment that is not an EST does not mean it is not effective, perhaps it has not been properly tested • Supporters of ESTs argue that the best scientific evidence should inform clinical practice Copyright © Allyn & Bacon 2009 How Do Bogus Therapies Fool Us? Spontaneous remission - unrelated to the therapy The placebo effect Self-serving biases - convince themselves they’ve been helped, if the patient has invested time and money Regression to the mean - extreme scores become less extreme on re-testing Retrospective rewriting of the past adjusting pretreatment memories Copyright © Allyn & Bacon 2009 Biological Treatments Pharmacotherapy – use of medications to treat psychological problems Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed to treat depression Drug companies claim these drugs fix a “chemical imbalance” in the brain, but the fact is that they likely work through complex mechanisms yet to be discovered Copyright © Allyn & Bacon 2009 Apply Your Thinking What makes you happy? What factors other than drugs, or psychotherapy might be effective at treating mild depression? Researchers have found that natural light makes people happier. This is believed to be involved in seasonal affective disorder, but can also be applied to clinically depressed patients. Patients given light therapy often respond as well as patients on antidepressant medications, and the effects are immediate. The reason you like the summer so much isn’t just because there’s no school! Copyright © Allyn & Bacon 2009 Cautions about Pharmacotherapy Side effects are usually reversible when the drug is discontinued, but some are not Tardive dyskinesia (TD) – irreversible side effect of some antipsychotic drugs causing involuntary movements of facial muscles and twitching of the neck, arms, and legs Different patients require different doses Sex, ethnicity, body weight can alter response Copyright © Allyn & Bacon 2009 Biological Treatments Electroconvulsive therapy (ECT) – brief electrical pulses to the brain which produce a seizure and treat serious psychological problems (last resort) Effective: 80-90% improvement rates Not as uncomfortable as it sounds • 98% of patients said they would have ECT again if their depression returned • Adverse side effects: • Memory and attention problems can persist 6 months after treatment Vagus nerve stimulation – electrical pulses to treat major depression Large scale study has not been done Copyright © Allyn & Bacon 2009 Psychosurgery Psychosurgery – brain surgery to treat psychological problems 1950s - researchers claimed that prefrontal lobotomies were effective treatments for a range of disorders • Heavy criticism of this practice • Surgeries became more targeted to decrease side effects • Today psychosurgery is used as an absolute last resort • Few well-controlled studies have been performed Copyright © Allyn & Bacon 2009
