What is Stress?

A byproduct of poor/inadequate coping skills

Factitious Disorder

Condition in which a person acts as if he or she has a physical or mental illness when he or she is not really sick. Formerly known as muhcausen's syndrome goes to extremes to cause/create illness

GAD Diagnostic criteria

A. Excessive anxiety and worry (apprehensive expectation), occurring more days than not for at least six months, about a number of events or activities B. The person finds it difficult to control the worry. C. The anxiety and worry are associated with three (or more) of the following six symptoms (with at least some symptoms present for more days than not for past 6 months). Note: Only one item is required in children: 1.restlessness or feeling keyed up or on edge 2. being easily fatigued 3. difficulty concentrating or the mind going blank 4. irritability 5. muscle tension 6. difficulty falling or staying asleep, or restless sleep D. The anxiety, worry, or physical symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning. E. The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., hyperthyroidism) and does not occur exclusively during a Mood Disorder, a Psychotic Disorder, or a Pervasive Developmental Disorder)

Commonality of anxiety disorders

Annual prevalence 18% Lifetime prevalence 29% Only ⅕ seek treatment Most common disorder in the U.S

Eating Disorder Onset

Anorexia - 16-20 yrs Bulimia - 21-24 yrs Binge Eating Disorder - 30-50 yrs

Panic Attack vs Anxiety Attack

Anxiety symptoms vary in intensity, from mild to severe. Panic attacks appear suddenly, while anxiety symptoms become gradually more intense over minutes, hours, or days. Panic attacks usually subside after a few minutes, while anxiety symptoms can prevail for long periods.

somatic symptom disorder Cognitive causes

Attentional bias by illness Prior experience with illness Trait-Based Risk factors

Excoriation Treatment

CBT

somatic symptom disorder Treatments

CBT ERP Medical management: doc only focuses on new complaints, antidepressants also helpful

Agoraphobia treatment

CBT exposure = most common and effective!

GAD Treatment

CBT, SSRI, SNRI = first line Buspirone, TCA, BZD = second line

SAD Treatment

CBT, medication (antidepressants, higher rate or relapse with meds)

Specific Phobia diagnostic criteria

Cardinal characteristics = avoidance of the object or situation Most phobias are categorized as specific but there are also broader disorders

Other factors that develop stress

Crises → overwhelms our coping strategies, very intense stressors that overwhelm any kind of coping skill Life changes → positive OR negative (getting married, having a kid) Perception of benefits → personal growth, if you can identify at least a positive aspect derived from that stressor you will most likely be able to manage it better

ED Comorbidities

Clinical Depression: AN = 68% BN = 63% BED = 50% OCD Substance Abuse Disorder: Binge/purge of BN & AN but NOT the restrictive type BED = 23% Personality Disorders: 58% of those with an ED also have a PD Some symptoms may be a consequence of malnourishment vs comorbid diagnosis

Treatment of ED

Clinical Depression: AN = 68% BN = 63% BED = 50% OCD Substance Abuse Disorder: Binge/purge of BN & AN but NOT the restrictive type BED = 23% Personality Disorders: 58% of those with an ED also have a PD Some symptoms may be a consequence of malnourishment vs comorbid diagnosis

Specific phobia psychoanalytic explanation

Defense against anxiety stemming from repressed id impulses

somatic symptom disorder Diagnosis criterion

(a) 1+ Somatic Symptoms, Chronic & Distressing o Pain is most common (b) Dysfunctional thoughts, feeling, behaviors about that symptom: o Disproportionate & persistent thoughts about seriousness of symptoms o High levels of anxiety about health or symptoms (c) Symptoms may not be persistently present o State of being symptomatic IS persistent (+6 months) o "I don't feel it now, but it is only a matter of time till it comes back"

Negative Stress

(distress) bad stress

Anorexia onset

- 16-20 yrs. Old - 0.9% in women - 0.3% in men

Risk factors for developing stress

- Genetics (polygenic component) - Experience 1+ crisis - Significant life events (+/-) - Individual perception of stressor - Individual Stress tolerance

Stress Protective Factors

- Male gender - older age - higher education - economic resources - positive outlook on life - self-confidence - social support

Dissociative disorders

- characterized by SIGNIFICANT memory loss, or identity disruption/failure

OCD diagnostic criteria

-recurrent obsessions or compulsions (or both) take up more than 1 hour a day or cause considerable stress to the individual -not caused by substance, medication use, or other disorders - interferes with daily functioning - causes great distress

Types of Dissociative Amnesia

1. Localized 2. Selective 3. Generalized 4. Continuous in all 4: procedural, semantic, and short-term memory systems stay intact, long-term is lost/disturbed

PTSD Causal Factors

1. Nature of trauma (e.g. human intent vs natural disaster) 2. Degree of direct exposure to event 2. Individual risk factors (female; neuroticism; family hist of or preexisting depr, anxiety, subst abuse) (biological: s/s genotype, smaller hippocampus, cortisol response [women]) 3. Sociocultural risk factors (social isolation)

What systems are activated with the "normal" stress response?

1. Sympathetic-adrenomedullary (SAM) system - fight or flight responses 2. Hypothalamus-pituitary-adrenal (HPA) system - releases cortisol 3. Parasympathetic Nervous (PNS) system - When the perceived danger passes, the PNS helps return body processes to normal levels (homeostasis)

SAD Prevalence and Comorbidity

12% lifetime Women more 2:1 Typically adolescence of early adulthood · Other anxiety disorders · Depression (50%) · Substance abuse (to reduce anxiety → 33%)

Why are rates of suicidal ideation and attempts higher for panic disorder?

?

PTSD Treatment

Cognitive behavioral therapy exposure therapy antidepressants/antipsychotics

Comorbidities of anxiety disorders

Depression another anxiety disorder 2 or more anxiety disorders caused by the other 55% 2 or more individual anxiety disorders 26% 1 anxiety disorder only 19%

BDD comorbidity

Depression (50%) Suicide

Eating Disorder gender differences

Female : Male - 10:1 → 3:1 Due to stigma in being diagnosed Woman tend to be more appearance-focused than man Gay & bisexual men > heterosexual men

GAD: The Psychodynamic Perspective

Freud believed that all people experience anxiety, use defense mechanisms to help control it (conflicting id & ego) 3 types: Realistic, Neurotic, Moral

Specific Phobia biological perspective

GENETICS Superior fear conditioning enhance resistance to extinction Identical twins are more likely to share animal and situational phobias

Biological formulation (GAD)

Genetics, neurotransmitters (GABA, serotonin), HPA system

Conversion Disorder Treatment

Integrating the subpersonalities Integration into a single identity Integration is a continuous process Following integration, further therapy is typically needed to: Maintain the complete personality Teach social and coping skills to prevent later dissociation Treatment is based on POSTTRAUMATIC THEORY Hypnosis commonly used Uncovers & processes traumatic experiences Less successful than treatment for DA

Acute stress disorder diagnostic criteria

Intrusion symptoms = nightmares, intrusive images, physiological reactivity to trauma reminders Negative mood = persistent inability to experience positive mood Dissociative symptoms = being in a daze, time slowing, observing oneself from others perspective, impaired memory of an event Avoidance symptoms = efforts to avoid thoughts, feelin, or reminders Arousal symptoms = hypervigilance, excessive response when startled, irritability, disturbed sleep, difficulty concentrating

Agoraphobia Prevalence/Comorbidity

PREVALENCE: Þ 1.4% lifetime Þ 2:1 - Women to Men COMORBIDITY: Þ Panic disorder

GAD: The Cognitive Perspective

Perception of uncontrollability and unpredictability Negative consequences of worry Cognitive biases (anxious people are more attuned to threatening cues // non anxious show no bias or opposite bias)

Hoarding Disorder

Persistent difficulty discarding or parting with possessions, regardless of their actual value

Specific phobia behavioral explanation

Phobias are learned behavior Maintained through avoidance May developing in GAD when a person acquires a large number of them

OCD treatment

Psychotherapy treatment = exposure and response prevention (ERP) Clients are repeatedly exposed to anxiety provoking stimuli and are told to resist performing the compulsions. Gradually move through hierarchy of stimuli 76% improve 25% fail to improve THERAPY ALONE (VS COMBINED WITH MEDS) MAY BE MOST EFFECTIVE

Excoriation (Skin-Picking) Disorder

Recurrent skin picking resulting in skin lesions Spend significant time per day

why does PTSD develop?

SAM systems = fight or flight freeze response It is unconscious, automatic, and normal

Eating Disorders

Severe disturbances in eating behavior characterized by preoccupation with weight concerns and unhealthy efforts to control weight.

Key factors of stressors

Severity → stressors that are more severe in nature will more likely impact the individual Chronicity → the longer that the stressor operates, the longer that the stressor will be present, and the consequences will be worst Timing → how close in time do stressors occur? If in close succession, the stress' impact and potency will increase substantially Degree of impact → if more closely involved in a situation, it will impact you more Predictability → if we can predict a stress coming up, we can prepare ourselves mentally. If unpredictable, it will lead to higher levels of stress Controllability → if there's no way to reduce impact of stressor, there will be a higher likelihood of stress development

Binge-Purge Cycle

Tension / cravings Binge eating Purge to avoid wt. gain Shame/guilt/disgust Strict dieting

Trichotillomania (Hair-Pulling Disorder)

The compulsive, persistent urge to pull out one's own hair. Must cause clinically significant distress

ANXIETY

The condition of feeling uneasy or worried about what may happen

ED prevalence

U.S. Lifetime Prevalence: Bulimia - 1.5% women, 0.05% men Anorexia - 0.9% women, 0.3% men Binge Eating - 3.5% women, 2% men In obese people → 6.5-8% Occupations: Women: dancers (ballet), models, actresses Men: jockeys, wrestlers, distance runners, body builders, swimmers

Impact of relationships & social support on PTSD?

We know that the impact of a relationship can either cause PTSD or help ease the symptoms with social support and a strong social circle. An emotions trauma that can cause PTSD symptoms is infidelity the three stages of recovering from PTSD causes by a partners infidelity Absorbing the blow Giving meaning, establishing new assumptions Moving forward

Generalized Anxiety Disorder (GAD)

a diffuse state of constant anxiety not associated with any specific object or event

obsessive-compulsive disorder (OCD)

a disorder in which repetitive, intrusive thoughts (obsessions) and ritualistic behaviors (compulsions) designed to fend off those thoughts interfere significantly with an individual's functioning

Panic Disorder formulations

a. BIOLOGICAL PERSPECTIVES: ¯ GENETICS o 30-34% due to genes ¯ BRAIN FUNCTIONING o Amygdala o Hippocampus o Higher cortical centers § EXTREME stimulation in these areas ¯ BIOCHEMICAL o Panic provocation procedure (fear network that is activated more quickly) o Noradrenergic & Serotonergic systems → not functioning properly, intense physiological responses develop o Low levels of GABA & Serotonin b. PSYCHOLOGICAL PERSPECTIVE ¯ Cognitive Theory of Panic: o Panic-prone individuals are very sensitive to certain bodily sensations § Interpret them as medical catastrophe (automatic thoughts) ¯ Learning Theory of Panic: o Panic attack becomes associated with neutral internal & external cues (interoceptive & exteroceptive conditioning) § The more intense the panic attack, the more robust the conditioning will be ¯ Anxiety Sensitivity: o Focus on bodily sensations § Unable to assess logically, interpret as potentially harmful

PTSD Symptom Cluster (need to have 1+)

a. Intrusion Symptoms (+1) → nightmares, intrusive images, physiological reactivity to trauma reminders b. Avoidance Symptoms (+1) → efforts to avoid thoughts, feelings, or reminders of trauma c. Negative Alterations in Cognition and Mood (+2) → detachment, shame, anger, distorted blame of self/pothers, impaired memory of event d. Arousal & Reactivity Symptoms (+2) → hypervigilance, excessive response when startled, irritability, disturbed sleep, difficulty concentrating DISSOCIATIVE SYMPTOMS: a. Depersonalization → persistent/recurrent experience of feeling detached from body (dream state; self or body isn't real; slow-motion time) b. Derealization → persistent/recurrent experiences that world is unreal, dreamlike, distant, distorted

Subpersonality Interactions

a. Mutually Amnesic Relationships → subpersonalities have NO awareness of one another b. Mutually Cognizant Patterns → each subpersonality is well aware of the rest c. One-Way Amnesic Relationships → some personalities are aware of others, but awareness is not mutual (most common) d. Co-conscious Subpersonalities → those that are aware are "quiet observers"

What Causes Conversion disorders?

a. POST-TRAUMATIC THEORY: · 95% patients with DID report severe, horrific childhood abuse · Child attempts to cope with abuse by dissociating - escape into fantasy/become someone else o Reduction in pain → reinforcement o Children who are fantasy-prone & easily hypnotized have diathesis for DID · Complex PTSD? o Anxiety: PTSD > DID o Dissociation: PTSD < DID b. SOCIOCOGNITIVE THEORY: · Highly susceptible person learns to adopt & enact multiple identities following inadvertent behaviors of clinicians o Through suggestion, legitimization, or reinforcement clinicians are responsible for eliciting disorder o Study found that identities could be induced

Cause of Eating Disorders

a. PSYCHODYNAMIC THEORIES: ¯ Parents respond to their children ineffectively, failing to attend to biological + emotional needs ¯ Deficiencies in parenting contribute to a broad cognitive distortion underlying disordered eating o Negative self-judgement based on body shape and weight ¯ ANOREXIA o Stems from an effort to delay/interrupt sexual maturation o Reflects a passive-aggressive response to conflicts around control & autonomy ¯ BULIMIA o reflects self-nurturing with food in the absence of adequate parental nurturing BIOLOGICAL FACTORS: ¯ Serotonin malfunction ¯ Hypothalamus and related brain areas may be responsible for weight "set-point" or "weight thermostat" o Set by genetic inheritance & early eating practices o Mechanism responsible for keeping an individual at a particular weight level § If weight falls below set point: hunger, metabolic rate → binges § If weight rises above set point: hunger, metabolic rate o ANOREXIA § is a constant fight to reduce hunger MOOD DISORDERS: ¯ Persons with EDs have higher rates of major depressive disorder ¯ People with EDs (especially BN), have serotonin abnormalities o Symptoms of EDs are helped by antidepressant meds SOCIOCULTURAL FACTORS: ¯ Societal pressures → western standards of attractiveness may contribute to emergence of EDs o Western standards have changed throughout history: § "Thinner" → ideal for women § "Muscular" → ideal for men o Models, actors, dancers, athletes are at higher risk for EDs § 9% collegiate athletes full criteria for ED § 50% has 1 or more symptoms § 20% gymnast appear to have EDs ¯ Socially accepted prejudice against overweight people may also add the "fear" and preoccupation about weight o Estimated that as many as 50% of elementary, 61% of middle school girls are dieting e. FAMILY INFLUENCES - play important roles in developing EDs ¯ Half of families of those with EDs, have long history of emphasizing thinness, appearance, dieting ¯ Emphasis on propriety and rule-mindedness ¯ Parental over-direction of child or subtle discouragement of autonomous strivings o Poor skills in conflict resolution ¯ Preoccupations regarding desirability of thinness, dieting, good physique d. INDIVIDUAL RISK FCATORS: ¯ Gender o Female - AN, BN most common o Male - BED most common o Sexual orientation - risk for males ¯ Internalization of thin ideal o Perfectionism o Negative body image ¯ Dieting ¯ Negative emotionally ¯ Childhood sexual abuse

SAD Formulations

a. PSYCHOLOGICAL FACTORS ¯ Learned or vicarious behaviors ¯ Perceptions of uncontrollability & unpredictability -- People are unpredictable, you don't have control over them b. BIOLOGICAL FACTORS ¯ Genetics: 12-30% of variance due to genes ¯ Temperament: behavioral inhibition

What Causes dissociative disorders?

a. PSYCHOLOGICAL PERSPECTIVE: ¯ Unconscious attempts to avoid thoughts about a situation o Physical Avoidance ¯ Presented w/ unpleasant situation o no clear way to escape o large segments of personality and memory are suppressed BRAIN IMAGING: ¯ Case studies show differences in brain activity ¯ Frontal & temporal regions

dissociative fugue

a. extreme case of dissociative amnesia, people not only forget their personal identities and details of the past but also flee to an entirely different location o For some is brief, matter of hours or days, and ends suddenly o For others is more severe: people may travel far from home, take a new name, establish new relationships, new work (new personality characteristics) Þ FUGUE = FLIGHT Þ 0.2% population → it usually follows a stressful event Þ Ends abruptly → therapists may have to constantly remind them of their own identity Þ Most people regain most or all of their memories → never have a recurrence

Anorexia Nervosa

an eating disorder in which an irrational fear of weight gain leads people to starve themselves *significantly underweight*

Panic Disorder treatments

antidepressant drugs restore proper norepinephrine activity in locus coeruleus and help reduce panic / cognitive behavioral therapy Improvement in 80% of patients Anxiolytics like xanax are also effective Antidepressants are better Therapy = psychoeducation, teach about accurate interpretations of bodily sensations, coping skills, combine with behavioral therapy like exposure Effective 70-90% become panic free Useful for panic disorder with agoraphobia

PSYCHODYNAMIC PERSPECTIVE: ¯ Anxiety disorders develop when children come to fear their impulses and use ego defense mechanisms to lessen their anxiety ¯ OCD differs from other anxiety disorders in that the "battle" is not unconscious; it is played out in overt thoughts and actions o Id impulses = obsessive thoughts (e.g., reaction formation) o Ego defenses = compulsive actions (e.g., undoing) c. BEHAVIORAL & COGNITIVE PERSPECTIVE ¯ Cognitive Therapists focus on the cognitive processes that help to produce and maintain obsession o Suppressing unwanted thoughts INCREASE thoughts → not an effective way o Those with OCD have cognitive biases toward material relative to their obsessions ¯ Thought-Action Fusion
