Therapies: Historical and Contemporary Approaches

Historical Approaches to Mental Health Treatment

The treatment of mental health disorders has evolved significantly over the centuries, moving from institutionalization to more humane and effective methods. Early institutions in the 1400s were often characterized by brutal conditions, while the late 1800s saw overcrowded asylums and ineffective treatments such as cold water submersion and electroshock therapy. The 1960s marked a turning point with the discovery of antipsychotic medications, deinstitutionalization, and the establishment of residential treatment centers.

• Institutionalization: Early mental health care relied on large asylums, often with poor conditions.

• Deinstitutionalization: Shifted care to community settings, but led to increased homelessness among mentally ill individuals.

• Modern Treatment: Focuses on short-term care in psychiatric hospitals and community-based services.

Mental Health and Homelessness

Mental health issues are prevalent among homeless populations, with youth and Indigenous individuals experiencing higher rates of mental health and substance use challenges. Deinstitutionalization has contributed to the intersection of mental illness, homelessness, and involvement with the justice system.

• Prevalence: 85% of homeless individuals report at least one health challenge.

• Youth: Highest prevalence of mental health issues (67%).

• Indigenous Populations: Higher rates of substance use compared to non-Indigenous.

The Courts and Mental Health

The legal system may compel individuals with severe mental health issues to enter treatment, often through community treatment orders. These orders require individuals to live in the community under legally mandated treatment conditions, such as taking medication and attending psychiatric appointments. The issue is controversial, balancing individual rights with public safety.

• Community Treatment Orders: Legal mandates for treatment in the community.

• Controversy: Concerns about rights and resource shortages.

Barriers to Psychological Treatment

General Barriers

Access to psychological treatment is hindered by several factors, including stigma, ambiguous disorders, cultural attitudes, gender roles, geographical and financial barriers.

• Stigma: Negative perceptions about mental illness discourage seeking help.

• Cultural Barriers: Therapy is less common in collectivist cultures and among certain ethnic groups.

• Financial and Geographical Barriers: Limited access in rural areas and lack of coverage for private therapy.

Men and Mental Health

Men face unique barriers to mental health treatment, including masculinity norms, symptom recognition, attitudinal barriers, stigma, and service fit. These factors contribute to lower rates of help-seeking among men.

• Masculinity Norms: Emotional disclosure seen as weakness.

• Symptom Recognition: Depression may manifest as anger or substance use.

• Attitudinal Barriers: Preference for self-reliance and discomfort with vulnerability.

• Stigma: Fear of judgment from peers and family.

• Service Fit: Services not always tailored to men's communication styles.

Types of Therapists and Sources of Treatment

Types of Therapists

Different professionals provide mental health treatment, each with specific qualifications and roles.

• Clinical Psychologists: PhD or PsyD, specialize in assessment and treatment.

• Counselling Psychologists: PhD, EdD, or master's, focus on adjustment problems.

• Psychiatrists: MDs, can prescribe medication, treat severe disorders.

• Psychoanalysts: Specialize in psychoanalysis, often MDs or psychologists.

• Registered Psychotherapists: Provide therapy, varying educational backgrounds.

• Licensed Professional Counsellors: Master's degree, certified, work with individuals and families.

• Clinical/Psychiatric Social Workers: Master's degree, focus on family and personal problems.

Insight Therapies

Psychoanalysis

Psychoanalysis, developed by Freud, aims to release unconscious thoughts and feelings to reduce their influence on behavior. Techniques include free association and dream analysis. Resistance and transference are common phenomena in psychoanalytic therapy.

• Free Association: Patient says whatever comes to mind.

• Dream Analysis: Therapist interprets dreams.

• Resistance: Unwillingness to discuss certain topics.

• Transference: Transfer of feelings to the therapist.

Psychodynamic Therapy

Modern psychodynamic therapy is shorter in duration and focuses on early childhood experiences and emotional attachments. It is partially empirically supported, especially for panic disorder, opiate addiction, and borderline personality disorder.

• Object Relations Therapy: Focuses on early relationships and their impact.

• Empirical Support: Promising for certain disorders.

Person-Centered Therapy

Person-centered therapy emphasizes the therapeutic relationship, self-actualization, and empathy. It is a non-directive, humanistic approach that supports clients' innate ability to heal.

• Core Conditions: Congruence, unconditional positive regard, empathy.

• Therapeutic Alliance: Strong predictor of success.

Behavioral Approaches

Classical Conditioning Techniques

Behavioral therapies apply principles of learning to change undesirable behaviors. Classical conditioning techniques include aversive conditioning, systematic desensitization, and flooding.

• Aversive Conditioning: Uses unpleasant stimuli to stop unwanted behaviors.

• Systematic Desensitization: Gradual exposure to anxiety-provoking stimuli paired with relaxation.

• Flooding: Rapid exposure to feared stimuli.

Operant Conditioning Techniques

Operant conditioning techniques reward desirable behaviors and extinguish negative behaviors. Methods include token systems, contingency contracting, and observational learning.

• Token System: Rewards for desirable behaviors.

• Contingency Contracting: Written agreements outlining goals and consequences.

• Observational Learning: Modeling behaviors to teach new skills.

Evaluation of Behavioral Therapy

• Advantages: Effective for phobias, compulsions, and social skills.

• Disadvantages: Does not address underlying thoughts or severe disorders.

Cognitive-Behavioral Therapies (CBT)

Principles and Techniques

CBT, developed by Aaron Beck, assumes negative emotions stem from faulty thinking. It helps clients restructure negative beliefs, face avoided situations, and regain emotional control.

• Cognitive Restructuring: Rethink negative beliefs.

• Exposure: Face avoided situations.

• Relaxation: Regain emotional control.

Dysfunctional Thinking Patterns

Depression is often associated with dysfunctional thinking patterns, such as internal, stable, and global attributions.

• Internal Attributions: "It's all my fault."

• Stable Attributions: "It's never going to change."

• Global Attributions: "My whole life is ruined."

Dialectical Behavioral Therapy (DBT)

DBT focuses on acceptance and change, teaching behavioral skills for emotional regulation, distress tolerance, mindfulness, and interpersonal effectiveness. It is especially effective for personality disorders.

• Distress Tolerance: Negative emotions are inevitable but temporary.

• Mindfulness Training: Attention to present experiences without judgment.

Interoceptive Exposure Therapy

Used for panic disorder, this therapy involves purposefully arousing symptoms of a panic attack to help clients perceive them as harmless.

• Examples: Spinning in a chair, breathing through a straw, stair climbing.

Mindfulness-Based Cognitive Therapy

This approach combines mindfulness meditation with CBT tools, encouraging clients to "decenter" and observe themselves objectively.

Evaluation of CBT

• Advantages: Effective for anxiety, depression, substance abuse, eating disorders.

• Disadvantages: May not address irrational aspects of life.

Group and Family Therapies

Group Therapy

Group therapy involves multiple clients meeting with a therapist, providing support and advice. It is economical and can be tailored to specific needs.

• Self-Help Groups: Peer-led support (e.g., Alcoholics Anonymous).

• Family Therapy: Focuses on adopting constructive roles and patterns.

Effectiveness of Therapy

Psychotherapy is generally effective for most people, though not universally. Therapists often use an eclectic approach, combining methods to suit individual needs. Different treatments are more effective for specific problems.

• Eclectic Approach: Combining multiple therapeutic methods.

• Effectiveness: Varies by treatment type and disorder.

Biomedical Therapies

Antipsychotic Drugs

Antipsychotic drugs temporarily reduce psychotic symptoms by blocking dopamine receptors. Newer antipsychotics may increase dopamine in specific brain regions.

• Examples: Clozapine, other atypical antipsychotics.

Antianxiety Drugs

Benzodiazepines (e.g., Xanax, Valium, Ativan) reduce excitability and increase well-being by affecting GABA activity. They carry risks of dependence and lethality when combined with alcohol.

• Mechanism: Enhance GABA activity.

• Risks: Dependence, overdose.

Antidepressant Drugs

Antidepressants improve well-being and are used for anxiety disorders. Types include tricyclics, MAO inhibitors, and selective serotonin reuptake inhibitors (SSRIs).

• Tricyclics: Increase norepinephrine.

• MAO Inhibitors: Prevent breakdown of neurotransmitters.

• SSRIs: Target serotonin, e.g., Prozac, Zoloft.

Herbal Remedies

St. John's Wort is a herbal supplement shown to reduce depression, but quality is not standardized and it may interact with other medications.

New Directions in Psychopharmacology

Ketamine therapy and transcranial magnetic stimulation (TMS) are emerging treatments for depression, especially treatment-resistant cases. ECT is used for severe depression but remains controversial due to side effects.

• Ketamine: Blocks NMDA receptor, affects glutamate.

• TMS: Magnetic pulses activate neurons.

• ECT: Electric current administered under sedation.

Psychosurgery

Historically, lobotomies and lesions were used for severe disorders. Modern psychosurgery is a last resort for severe OCD, depression, and bipolar disorder.

Biomedical Therapies in Perspective

• Revolutionized Treatment: More patients treated as outpatients.

• Limitations: Temporary symptom relief, not a cure-all, serious side effects.

Controversial and Emerging Therapies

Eye Movement Desensitization and Reprocessing (EMDR)

EMDR involves recalling traumatic events while performing rapid eye movements. It is controversial due to limited evidence and unclear mechanisms.

• Technique: Tracking an object while recalling trauma.

• Controversy: Lack of strong research support.

On Being Sane in Insane Places (Rosenhan Study)

The Rosenhan study demonstrated the challenges of psychiatric diagnosis by having sane individuals gain admission to mental hospitals. The study highlighted issues of depersonalization and the reliability of psychiatric labels.

• Findings: Sane individuals were diagnosed as schizophrenic and received little attention.

• Implications: Raised questions about the validity of psychiatric diagnosis.
