Abnormal Psych. Midterm 2 (ch. 5-10) Flashcards
Stressors
External or internal demands
Stress
The effects of external and internal demands on an organism that exceeds the persons resources.
Coping strategies
Efforts to deal with stress
Distress
- Bad stress
- Potential to do more damage than stress occurring in positive situations
- Can be a continuous force that exceeds persons capability of managing it
Individual characteristics identified as improving ability to handle life stress include?
- Levels of optimism
- Greater psychological control or mastery
- Increased self esteem
- Better social support
Genetic makeup can render us more or less stress sensitive, true or false?
- True: twin studies indicate differences in coping styles linked to genetic differences
Stress tolerance
Person’s ability to withstand stress without becoming seriously impaired
Uncontrollable vs. predictable stress
- Unpredictable and unanticipated events likely to lead to severe stress (no coping strategy available)
- More stress with unpredictable events
Crisis
- When a stressful situation threatens or exceeds the adaptive capacities of a person or a group, overwhelming the person
- Sudden and intense crisis
- Stress very potent, coping techniques don’t work
Cortisol
- Stress glucocorticoid in humans that is produced
- Good hormone during emergency, prep. fight or flight
- If cortisone is active for long periods of time, not shut off, damage to brain. Very problematic
Stress and social support
- People who have relatively small social networks or who consider themselves to have little emotional support are more likely to develop CHD
- Lack of social support triggers inflammatory response
- Emotional disclosure effective therapy to decrease stress hormones
Resilience
- The ability to adapt and function healthily after a potentially traumatic event
- Factors that increase resilience: being male, being older, being well educated, having more economic resources, being optimistic and scoring high on positive affect and low on negative affect.
Type A behavior pattern
- Characterized by excessive competitive drive, extreme commitment to work, impatience or time urgency, and hostility
- Hostility in type A people is correlated coronary heart disease
Adjustment disorder
- Stress disorder that overwhelms ability to adjust and cope
- Stressor is something commonly experienced (divorce, death of loved one, loss of job)
- Results in clinically significant behavioral or emotional symptoms
- Stress can be single event, or multiple stressors
- Symptoms must begin within 3 months of onset of the stressor
- Must experience more distress than what would be expected
- Symptoms lessen when stressor ends or person learns to adapt to stressor
- If symptoms continue past 6 months, diagnosis is usually changed to another mental disorder
PTSD
- Stress disorder that overwhelms ability to adjust and cope
- Must have been exposed to a traumatic stressor that is accompanied by fear, helplessness, and horror
- Must have a clear, explicit, extreme, terrifying stressor that was life threatening and outside ordinary bounds
- Stressors include combat, rape, being confined to concentration camp, experiencing a natural disaster.
- Those who develop acute stress disorder are at an increased risk of developing PTSD
Acute stress disorder
- Diagnostic category used when symptoms develop shortly after experiencing a traumatic event and last at least 2 days
- If symptoms persist longer than 4 weeks, diagnosis can be changed to PTSD
Clinical description of PTSD (4 parts)
- Intrusion: recurrent re experiencing of traumatic event through nightmares, intrusive images, and physiological reactivity to reminders of the trauma (does not include rumination)
- Avoidance: avoidance of thoughts, feelings, reminders of the trauma
- Negative cognitions and mood: symptoms as feelings of detachment, negative emotional states like anger, shame, or distorted blame for oneself or others
- Arousal and reactivity: hyper vigilance, excessive response when startled, aggression, reckless behavior
Treatment for PTSD
- Telephone hotlines
- Crisis intervention: brief duration therapy that focuses on immediate emotional problem
- Psychological debriefing: structured emotional support that encourages talking about experiences of crisis. No empirical evidence to support benefits
- Medications: antidepressants, antipsychotics
- Prolonged exposure: a CBT therapy, patient asked to repeat traumatic event over and over until a decrease in emotional response. Drop out rate high, long term effects not as long lasting as thought
- CBT: very effective approach, treatment gains continue after treatment has ended, drop out rate low.
- Virtual reality exposure: program customized to reflect soldiers traumatic experience. Shows substantial decreases in PTSD, preferred over talk therapy by soldiers
Difference between fear and anxiety
How are they related
- Anxiety involves a general feeling of apprehension about possible future danger, unpleasant emotions orientated to the future. It may prime persons for readiness to deal with danger should it occur. Anxiety actually enhances learning and performance in mild to moderate degrees. Anxiety disorders treated with medication and CBT
- Fear is an alarm reaction that occurs in response to immediate danger (activation of the fight or flight, instantaneous reaction)
- Anxiety disorders share symptoms of clinically significant fear or anxiety. Both responses are learned through conditioning
Phobias
- Most common anxiety disorder
- Persistent and disproportionate fear of some specific object or situation that presents little or no actual danger and yet leads to a great deal of avoidance of these feared situations
- Exposure therapy: best treatment for specific phobias: controlled exposure to the stimuli or situation that elicits phobic fear.
- Participant modeling: therapist models ways of interacting with phobic stimulus
- Virtual reality shows relative efficacy
- Cognitive restructuring and medications for social phobias and agoraphobia
Mood disorders
- Involve much more severe alterations in mood for much longer periods of time
- Mania: intense and unrealistic feelings of excitement and euphoria
- Depression: feelings of extraordinary sadness and dejection.
Major Depressive Disorder
- Must be in a major depressive episode and never have had a manic, hypomanic, or mixed episode
- Must have 5 or more symptoms over a 2 week period every day for most of the day, and show change in previous functioning
- Depressed mood, loss of interest/pleasure, weight loss/gain, Sleep disturbances, feelings of worthlessness/ guilt, indecisiveness/ inability to concentrate, reoccurring thoughts of death
- High levels of comorbity between depressive and anxiety disorders
Manic episode vs. hypo manic episode
- Manic episode: elevated, euphoric or expansive mood, often interrupted by occasional outbursts of intense irritability or even violence. Mood must persist for at least a week plus 3 or more symptoms
- Hypomanic episode: milder form, abnormally elevated, expansive, or irritable mood for at least 4 days plus 3 or more symptoms
