Module 4 Part 2: Therapy
Therapeutic approaches each have unique methods and principles for addressing various mental health issues, emphasizing different aspects such as behavior, cognition, emotions, and personal growth.
Understanding the approaches can help in selecting the appropriate treatment for different psychological conditions.
Cognitive Therapy. A type of psychotherapy that focuses on changing maladaptive or irrational thoughts to improve emotional well-being and behavior.
Process
Identifying Cognitive Distortions: Recognizing irrational or distorted thoughts.
Challenging Thoughts: Questioning and challenging these thoughts.
Replacing Thoughts: Replacing distorted thoughts with more realistic and positive ones.
Example: Addressing a person's belief that they are worthless and replacing it with evidence-based affirmations of their abilities and worth.
Dialectical Behavior Therapy (DBT). A type of cognitive-behavioral therapy designed to treat borderline personality disorder and other conditions involving emotional dysregulation.
Components
Mindfulness: Teaching clients to be present in the moment.
Distress Tolerance: Helping clients tolerate and cope with distress without resorting to harmful behaviors.
Emotional Regulation: Identifying and managing intense emotions.
Interpersonal Effectiveness: Improving relationships and communication skills.
Example: Using DBT techniques to help a client with self-harm behaviors manage their emotions and improve their interpersonal relationships.
Psychoanalysis. A therapeutic approach developed by Sigmund Freud that focuses on exploring unconscious conflicts and desires.
Techniques
Free Association: Encouraging clients to speak freely to uncover unconscious thoughts and feelings.
Dream Analysis: Interpreting dreams to understand unconscious desires.
Transference: Exploring the client's feelings about the therapist to understand past relationships.
Example: Using free association to uncover repressed memories from childhood that influence current behavior.
Humanistic Therapy. A therapeutic approach that emphasizes personal growth, self-actualization, and the client's subjective experience.
Key Concepts
Unconditional Positive Regard: Providing a non-judgmental and accepting environment.
Empathy: Understanding the client's feelings and perspectives.
Authenticity: Being genuine and transparent as a therapist.
Example: Encouraging a client to explore their feelings and experiences to discover their true potential and self-worth.
Cognitive-Behavioral Therapy (CBT). A widely used therapeutic approach that combines cognitive and behavioral techniques to change maladaptive thoughts and behaviors.
Process
Identifying Problems: Recognizing problematic thoughts and behaviors.
Challenging and Changing: Developing strategies to challenge and change these thoughts and behaviors.
Skill Building: Teaching coping and problem-solving skills.
Example: Using CBT to help someone with social anxiety challenge their negative thoughts about social situations and develop social skills.
Person-Centered Therapy. A humanistic approach developed by Carl Rogers that emphasizes the client's capacity for self-direction and growth.
Key Elements
Unconditional Positive Regard: Accepting and valuing the client without judgment.
Empathy: Deeply understanding the client's feelings.
Congruence: Being genuine and authentic as a therapist.
Example: Providing a supportive and non-judgmental environment where a client feels safe to explore their thoughts and feelings.
Behavior Therapy. A therapeutic approach that focuses on changing maladaptive behaviors through conditioning and reinforcement techniques.
Techniques
Exposure Therapy: Gradual exposure to feared objects or situations.
Reinforcement: Using positive or negative reinforcement to encourage desired behaviors.
Modeling: Learning behaviors through observing others.
Example: Using exposure therapy to help someone with a phobia of spiders by gradually increasing their exposure to spiders in a controlled manner.
Systematic Desensitization. A behavioral therapy technique used to reduce anxiety or fear associated with a particular object, situation, or activity.
Process
Hierarchy Creation: The therapist and client create a list of anxiety-provoking situations arranged from least to most distressing.
Relaxation Training: The client learns relaxation techniques, such as deep breathing or progressive muscle relaxation.
Gradual Exposure: The client is gradually exposed to the anxiety-provoking situations while using relaxation techniques, starting from the least distressing and moving up the hierarchy.
Example: Gradually exposing someone with a fear of flying to pictures of planes, then visits to an airport, and eventually short flights.
Aversive Conditioning. A behavioral therapy technique that pairs an undesirable behavior with an unpleasant stimulus to reduce the behavior.
Process
Pairing: The undesirable behavior is consistently paired with an aversive stimulus, such as a bad taste, electric shock, or nausea-inducing drug.
Example: Using a nausea-inducing drug to treat alcoholism by pairing alcohol consumption with nausea.
Counterconditioning. A behavior therapy technique that involves replacing an undesirable response to a stimulus with a more desirable one.
Process
Exposure: The client is exposed to the stimulus that elicits the undesirable response.
Pairing: The stimulus is then paired with a new response that is incompatible with the undesirable response.
Example: Teaching a child to associate the presence of a feared animal with a positive activity, like playing with a favorite toy.
Medications are used to manage symptoms of psychological disorders, improve quality of life, and enable individuals to function more effectively in their daily lives. They can help correct chemical imbalances in the brain that are associated with mental health conditions.
Common Types of Medications
Antidepressants. Treat depressive disorders, anxiety disorders, and certain chronic pain conditions.
Examples: Selective Serotonin Reuptake Inhibitors (SSRIs): Fluoxetine (Prozac), Sertraline (Zoloft)
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs): Venlafaxine (Effexor), Duloxetine (Cymbalta), Tricyclic Antidepressants (TCAs): Amitriptyline, Nortriptyline, Monoamine Oxidase Inhibitors (MAOIs): Phenelzine (Nardil), Tranylcypromine (Parnate)
Antipsychotics. Treat schizophrenia, bipolar disorder, severe depression, and other psychotic disorders.
Examples: First-Generation (Typical): Haloperidol (Haldol), Chlorpromazine (Thorazine), Second-Generation (Atypical): Risperidone (Risperdal), Olanzapine (Zyprexa), Aripiprazole (Abilify)
Mood Stabilizers. Manage bipolar disorder, particularly in controlling manic episodes and preventing mood swings.
Examples: Lithium, Valproate (Depakote), Lamotrigine (Lamictal)
Anxiolytics. Treat anxiety disorders, panic disorders, and sometimes insomnia.
Examples: Benzodiazepines: Alprazolam (Xanax), Diazepam (Valium), Lorazepam (Ativan), Non-Benzodiazepines: Buspirone (Buspar)
Stimulants. Treat attention-deficit/hyperactivity disorder (ADHD) and certain sleep disorders.
Examples: Methylphenidate (Ritalin), Amphetamine/Dextroamphetamine (Adderall)
Non-Stimulant ADHD Medications. Alternative treatments for ADHD.
Examples: Atomoxetine (Strattera), Guanfacine (Intuniv)
Mechanism of Action
Antidepressants: Increase levels of neurotransmitters like serotonin, norepinephrine, and dopamine to improve mood and reduce anxiety.
Antipsychotics: Block dopamine receptors and sometimes serotonin receptors to reduce psychotic symptoms like hallucinations and delusions.
Mood Stabilizers: Varying mechanisms; lithium affects sodium transport in nerve and muscle cells, while anticonvulsants like valproate and lamotrigine stabilize mood by modulating neurotransmitter release.
Anxiolytics: Enhance the effect of the neurotransmitter GABA to induce relaxation and reduce anxiety.
Stimulants: Increase levels of dopamine and norepinephrine to improve attention and focus.
Considerations
Side Effects: Each class of medication can have various side effects, ranging from mild to severe, which need to be managed by healthcare providers.
Monitoring: Regular monitoring by a healthcare provider is necessary to adjust dosages, manage side effects, and assess effectiveness.
Combination with Therapy: Medications are often most effective when combined with psychotherapy, such as cognitive-behavioral therapy (CBT) or other therapeutic approaches.
Individual Differences: Response to medications can vary widely among individuals, necessitating personalized treatment plans.
Summary. Medications for psychological disorders are used to manage and alleviate symptoms, enabling individuals to lead more functional lives. These medications work by targeting specific neurotransmitters in the brain and are often used in conjunction with psychotherapy and regular medical monitoring.
First-Generation Antipsychotics (FGAs): Also known as typical antipsychotics, these were the first class of drugs used to treat psychotic disorders.
Examples
Chlorpromazine (Thorazine)
Haloperidol (Haldol)
Fluphenazine (Prolixin)
Mechanism of Action. Primarily block dopamine D2 receptors in the brain, which reduces psychotic symptoms.
Efficacy. Effective in reducing positive symptoms of schizophrenia, such as hallucinations and delusions.
Side Effects
Extrapyramidal Symptoms (EPS): Motor control issues like tremors, rigidity, bradykinesia, and tardive dyskinesia.
Neuroleptic Malignant Syndrome (NMS): A potentially life-threatening condition with symptoms like high fever, confusion, and muscle rigidity.
Anticholinergic Effects: Dry mouth, constipation, urinary retention, blurred vision.
Sedation: Often causes drowsiness and lethargy.
Cost. Generally less expensive than newer antipsychotics.
Newer Antipsychotics (Second-Generation and Third-Generation Antipsychotics). Second-generation antipsychotics (SGAs) and third-generation antipsychotics (TGAs) are often referred to as atypical antipsychotics.
Examples
SGAs: Risperidone (Risperdal), Olanzapine (Zyprexa), Quetiapine (Seroquel)
TGAs: Aripiprazole (Abilify), Brexpiprazole (Rexulti), Cariprazine (Vraylar)
Mechanism of Action
SGAs: Block both dopamine D2 receptors and serotonin 5-HT2A receptors, which can improve both positive and negative symptoms of schizophrenia and reduce EPS.
TGAs: Act as dopamine system stabilizers, modulating dopamine activity rather than just blocking it.
Efficacy
Effective in treating both positive and negative symptoms of schizophrenia.
Often used to treat bipolar disorder and as adjuncts in major depressive disorder.
Side Effects
Metabolic Side Effects: Weight gain, diabetes, dyslipidemia.
Sedation: Varies between different medications.
Fewer EPS: Compared to FGAs, there is a lower risk of extrapyramidal symptoms.
Prolactin Elevation: Some SGAs can increase prolactin levels, leading to side effects like breast enlargement and lactation.
Cost. Generally more expensive than FGAs due to being newer medications.
Summary
First-Generation Antipsychotics (FGAs): Primarily block dopamine receptors, effective in treating positive symptoms of schizophrenia but associated with significant motor side effects (EPS).
Newer Antipsychotics (SGAs and TGAs): Target both dopamine and serotonin receptors, effective in treating both positive and negative symptoms, with fewer motor side effects but higher risks of metabolic side effects. They are generally more expensive but offer a broader treatment profile.
