Overview and Challenges of Psychological Treatment
Definition of Psychotherapy: Systematic efforts to apply psychosocial interventions to reduce distress, maladaptive behavior, or enhance adaptive functioning. * Contrast to Medical/Biological Interventions: Unlike medication or surgery, psychosocial interventions focus on change through interpersonal interaction and systematic experiences such as role-playing, practice, homework, and advice. * Goal: To address social, emotional, and behavioral problems that impair everyday life, ranging from formal psychiatric disorders to impairment caused by stress or life transitions.
Prevalence of Mental Disorders: * In a given year, approximately of the US population (about million out of million people) meets criteria for one or more psychiatric disorders. * Over a lifetime, approximately of the population meets criteria for at least one disorder. * These are likely conservative estimates as they exclude individuals who narrowly miss diagnostic criteria but still experience impairment.
Unmet Need for Services: * Approximately of individuals with a diagnosable mental disorder in the US do not receive treatment. * Disparities in Care: Members of minority groups have significantly less access. African Americans are less likely to have access ( vs. for European Americans), and Hispanic Americans are less likely to have adequate care ( vs. ).
Societal and Personal Costs: * Substance Abuse: Costs approximately billion annually in medical, criminal justice, accident, and lost earning costs. * Anxiety Disorders: Costs approximately billion annually in health-care and lost productivity. * Individual Impairment: Mental disorders are often more impairing than common chronic medical disorders, particularly in home, social, and relationship functioning. Depression has one of the largest impacts on disability.
Behavioral Techniques: Emergence and Evolution
Behavior Therapy Background: * Dominance of "talk therapy" and psychoanalysis (Freud, -) in the early th century relied on internal psychological workings and the therapeutic relationship. * Eysenck (, ) and Levitt (, ) Findings: About two-thirds () of patients improved with therapy, but about two-thirds () also improved without treatment, leading to skepticism about psychotherapy's effectiveness.
The Behaviorism Movement: * Effort to bring a scientific, objective approach to psychology (e.g., Bechterev, ; Watson, ). * Focused on classical conditioning (Pavlov) and operant conditioning over subjective experience. * Delineation of Behavior Therapy occurred in the s and s as isolated efforts (US, Canada, England, South Africa) coalesced into professional organizations (AABT, now ABCT).
Cognitive-Behavior Therapy (CBT): * Transition: Shift from strict behaviorism to include internal cognitive processes (thoughts, beliefs, expectations). * S-R vs. S-O-R Learning: * Stimulus-Response (S-R): Learning by pairing stimuli or behaviors and consequences. * Stimulus-Organism-Response (S-O-R): Emphasizes internal processes (the "") to explain learning, illustrated by Tolman's () "cognitive maps" in rats. * CBT Characteristics: * Assumes maladaptive cognitions underlie clinical problems. * Cognitive processes are central to change. * Often utilizes behavioral methods (practice, reinforcement) to change thoughts.
Third Wave Expansion: * Focuses on mindfulness, acceptance, and the therapeutic relationship. * Mindfulness: Awareness of current experience (e.g., Buddhist meditation roots). * Acceptance: Embracing private thoughts/experiences as legitimate reactions. * Acceptance and Commitment Therapy (ACT): Combines current experience attention with strategies for behavior change.
Evidence-Based Treatments (EBTs)
History: In the s, the focus shifted from theoretical allegiance to empirical support.
Common Criteria for EBT Designation (Table 13-1): 1. Random assignment to conditions. 2. Careful specification of the patient population. 3. Use of treatment manuals. 4. Multiple outcome measures with naïve raters. 5. Statistically significant differences compared to a comparison group. 6. Replication by independent investigators.
Status of Psychotherapy: Most therapies () have never been studied. EBTs are prioritized as a "first line of attack."
Specific Evidence-Based Treatments and Illustrations
Exposure-Based Treatments for Anxiety
Historical Foundation: Pavlov's laboratory research on "experimental neurosis" in dogs. Watson and Rayner's () study of "Little Albert" (conditioning anxiety) and Jones' () study of "Peter" (deconditioning anxiety).
Systematic Desensitization (Wolpe, ): Pairing deep relaxation with a hierarchy of anxiety-provoking situations (imagery or real-life).
Flooding: Exposure to high-intensity, anxiety-provoking situations without relaxation until habituation occurs.
Graduated Exposure: Successive approximations toward feared stimuli without necessary relaxation or maximized intensity.
Case Illustration (Vlaeyen et al., 02459815905AB19921960204024IQ19): * -year-old girl with trichotillomania (hair pulling). * Identified beliefs: Fear of father's disapproval, need for absolute competence. * Treatment: Weekly therapy to dispute cognitions, followed by self-instruction training (coping statements). * Outcome: Hair pulling reduced to near zero.
Cognitive Therapy (CT) for Depression
Creator: Aaron Beck ().
Negative Cognitive Triad: Negative thoughts toward (1) oneself, (2) the world, and (3) the future.
Method: Treating beliefs as hypotheses to be tested. Homework assignments to record negative thoughts and practice goal-directed activities.
Case Illustration (Chadwick & Trower, ): * -year-old male with schizophrenia, paranoid delusions, and depression. * Beliefs: "I am a bad person," "God is punishing me." * Multiple-baseline design across three beliefs. * Results: Conviction in beliefs and clinical depression dropped significantly.
Problem-Solving Skills Training (PSST)
Skills Deficits (Table 13-3): 1. Alternative solution thinking. 2. Means-end thinking. 3. Consequential thinking. 4. Causal thinking. 5. Sensitivity to interpersonal problems.
Case Illustration (Dawson et al., ): * Neglectful mothers referred by courts. * Trained via vignettes using modeling, shaping, and feedback. * Outcome: Improved child-rearing practices and restored custody for participants.
Dialectical Behavior Therapy (DBT)
Creator: Marsha Linehan () for Borderline Personality Disorder (BPD) and suicidality.
Synthesis: Acceptance (Zen/mindfulness) and Change (CBT).
Hierarchical Order of Targets: 1. Life-threatening behaviors. 2. Therapy-interfering behaviors. 3. Quality-of-life interfering behaviors. 4. Life skills (distress tolerance, mindfulness etc.).
Case Illustration (Low et al., 01257505700,00070\%1\% of US smokers annually, reaching underserved minorities effectively. * Self-Help: Internet-based modules for panic disorder and depression show effects comparable to individual therapy but are difficult for the public to differentiate from "quackery."
