Development Stages 1 & 2 Anxiety & Mood Disorders
The Scientific Method Science is a systematic pursuit of knowledge through observation • Forming a theory • Systematically gathering data to test a theory (Observations must be replicable) • Forming a Hypothesis (what should occur if the theory is true) Science proceeds by disproving theories
Science in Mental health Mental health is a term used to describe either a level of cognitive or emotional wellbeing or an absenceof a mental disorder
APA DSM-IV-TR American Psychiatric Association (2000) Diagnostic and Statistical Manual Revision IV, Text Revision Reliability & Validity – Psychometrics DSM is so widely accepted that a psychiatrist must classify their patients’ disorders according to DSM listing number in order to be reimbursed by government of insurance companies
Psychodynamics • Childhood experiences help shape adult personality • There are unconscious influences on behaviour • The causes and purposes of human behaviour are not always obvious Freud: Psychopathology results from unconscious conflict • Anecdotal evidence, not the scientific method Benefits of gameplay, maintenance of negative schema internal cognitive processes
Cognitive Behaviourism Thorndike (1874-1949): Law of Effect Behaviour that is followed by consequences satisfying to the organism will be repeated, and behaviour that is followed by noxious or unpleasant consequences will be discouraged Skinner (1904-1990): operant conditioning -Positive reinforcement -Negative reinforcement -Automatic reinforcement
Reinforcement of behaviour Problem behaviour is thought to be reinforced by four possible consequences: Getting attention Escaping from tasks Generating sensory feedback (automatic) Gaining access to desirable things or situations
Behavioural Treatments Trauma Fear Conduct Disorder Autistic Spectrum Disorder etc
Cognition Perceiving, recognising, conceiving, judging and Reasoning The learning process is far more complex than stimulus-response associations (behaviourism) The learner is an active interpreter of a situation using past experience in a cognitive set/schema
Attention Individuals with psychopathologies tend to focus their attention on threats or anxiety, producing events or situations in the environment. e.g. “The world is a dangerous place” • Self-fulfilling prophecy Many people who are depressed believe that they have no important effect on their surroundings regardless of what they do
Developmental Stages • Completing a developmental stage supports the healthy awakening of the next stage • Developmental behaviour usually graduates in sequence along with chronological age
Maslow’s Heirarchy of Needs • Needs on lower levels must be met before larger identities can be sustained. • Lower identities take their places as no less important, but supporting of a larger and more powerful whole. • A.H. Maslow, A Theory of Human Motivation, Psychological Review 50(4) (1943):370-96.
Stage 1: Womb – 12 months • Motor Functions and security • Stage 2: 6 months – 2 years old • Mobility and emotion • Stage 3: 18 months – 4 years old • Will and action • Stage 4: 4 – 7 years old • Social Identity • Stage 5: 7 – 12 years old • Social contract • Stage 6: Adolescence • Reconstitution • Stage 7: Early Adulthood and Beyond • Self-knowledge
Stage 1: Womb – 12 months • Formation of the physical body during prenatal development and infancy • Body growth is rapid at this stage • Motor operations: suck, eat, digest, grasp, crawl, stand, walk, manipulate objects, gravity • Little awareness of the outside world • Fused symbiosis with the mother • No separate sense of self • Awareness of survival and physical comfort
Stage 1: Comparative Models • Freud: Oral Stage • Oral cavity is primary focus of libidal energy • Characterised by under-nursing: pessimism, envy, suspicion and sarcasm • Characterised by over-nursing: optimistic, gullible, admiration for others • Conflicts in nursing: deprivation of sensory pleasure and mothering • Erikson: Trust vs Mistrust (predictability)
Stage 1: Comparative Models • Piaget: Sensory-motor stage 1 & 2 • All knowledge is acquired through senses • No sign of object permanence (ability to know that an object exists when it is out of reach of your senses) • Primary circular reactions: repetition of movement (e.g. touching hand and foot) • Vision can follow moving objects
Stage 1: Psychological Development • Basic psychological identity associates with the physical body. • The self is identified with biological urges • IAmhungry • When to eat, When to rest, Limitations of the body • Individuality & The feeling of having the right to exist • Independence & The right to take care of ourselves • Interaction & The right to have, contain and create • Self-preservation
Stage 1: Trauma • Trauma may result in fear, insecurity, confusion • Symptoms of disorganisation or depression • Feelings of insanity, excessive thinking • Little “grounding” – detachment from body and basic consensus reality structures • Anxiety in mundane tasks, hypervigilance (high responsiveness to stimuli and constant scanning of environment for threats) • Healthy development teaches security, focus, calm and vigilance
Stage 2: 6 months – 2 years • Visual acuity allows the child to focus on outside objects and gain a wider visual perspective • Awareness grows of objects outside of immediate range • “Hatching” (Mahler) – moving away from mother in brief episodes of independence • Begins to separate self from other eliciting • Fear and excitement • Diversity and choice
Stage 2: Emotions • Primary method of obtaining information about our well-being • Primary language prior to verbal language • Adds dimension and texture to the mind-body experience • Identification with emotional body • I am scared, rather than I have fear
Stage 2: Comparative models • Freud: Oral stage • The id: need, sensation and desire is the fundamental cause of motivation. • Seeing something, moving towards it, merging with it (usually through the mouth) • Erikson: • Trust vs mistrust • Attachment vs separation
Stage 2: Separation and Connection • Separation from the mother corresponds with separation of self from other • Separation from primary attachment figure leads to binary distinctions • Duality: • good-bad, • pleasure-pain, • closeness-distance, • self-other
Stage 2: Trauma Trauma may cause numbness (lack of feeling), disconnection with self Difficulty in knowing what we want Unhealthy sexuality Excessive inhibition Guilt
Anxiety Disorders ‘Angere’: to choke, to torment Fear: Reaction to immediate danger Anxiety: Apprehension over an anticipated problem Both are adaptive strategies A small degree of anxiety has been found to improve performance on laboratory tasks
Anxiety Disorders Specific Phobia Panic Disorder Separation Anxiety Disorder Generalised Anxiety Disorder Obsessive-Compulsive Disorder Post-Traumatic Stress Disorder
Anxiety Disorders Phobia: A disruptive fear of a particular object or situation that is out of proportion to any danger posed 3-5% prevalence in children and adolescents
Anxiety Disorders There is a great deal of overlap between Axis I Anxiety Disorders and axis II Personality Disorders. Personality disorders (e.g. Borderline, Paranoid, or Avoidant Personality Disorders) may be considered to evoke contrasting ways of perceiving and coping with Axis I disorders Children’s Anxiety may not be focused enough to make specific diagnoses useful for intervention. Culture influences the development of anxiety disorders
Specific Phobias • Alliumphobia • Fear of garlic • Musophobia • Fear of mice • Helienophobia • Fear of pseudoscientific terminology • Arachibutyrophobia • Fear of peanut butter sticking to the roof of the mouth www.phobialist.com
Specific Phobias 2 - 4% prevalence in children More common in girls Some have clear genetic influences (e.g. snakes, injections)
Social Phobia 1% prevalence in children and adolescents May lead to substance related disorders and depression 33% concordant with Avoidant Personality Disorder
Panic Disorder (w/without Agoraphobia • Panic attacks: • Intense apprehension, terror, feelings of impending doom • Choking, nausea, sweating, etc. • Recurrent, uncued panic attacks • Agoraphobia • Anxiety about situations in which it would be embarassing or difficult to escape
Separation Anxiety Disorder 2 – 4% prevalence from preschool Specific to children Often tied to stressful life event of loss/separation
Generalized Anxiety Disorder Unable to let go of a worrisome problem Typically chronic, beginning in adolescence or late adolescence
Obsessive-Compulsive Disorder (OCD) • 2% prevalence, common onset around age 10 • Obsessions: • Intrusive and recurring thoughts, images or impulses that are uncontrollable and come unbidden • e.g. contamination, safety, religious issues • Compulsions: • Repetitive, clearly excessive behaviours or mental acts to reduce anxiety caused by obsessive thoughts. • e.g. elaborate rituals of orderliness, repetitive, magically protective acts (superstitions) • Repeatedly checking that these acts are carried out • lack of confidence in memory, unduly concerned about gaps in memory
Obsessive-Compulsive Disorder (OCD) 78% of compulsives viewed their rituals as rather silly or absurd, but unable to stop performing them. Rituals allow attention to be drawn away from the obsessions. This perpetuated the obsessions, as thought supression makes thoughts stronger and more frequent Exposure and Ritual prevention (ERP)
Post-Traumatic Stress Disorder (PTSD) • Also Acute Stress Disorder • Extreme response to an actual stressor involving threatened death, serious injury, or threat of these. • E.g. war veterans, rape victims • Symptoms are categorised under • Re-experiencing the trauma (e.g. night terrors) • Avoidance of associated stimuli (numbing) • Increased arousal high anxiety (problems with sleep and concentration)
Anxiety Disorders • Comorbidity • Over 50% of those diagnosed meet criteria for another anxiety disorder • ~60% of people in treatment for Anxiety disorders meet criteria for Depression • Substance disorders and Personality Disorders • Women are twice as likely to be diagnosed with anxiety disorders (except in OCD) • Syndromes are related to beliefs and attitudes of specific cultures
Common Etiology of Anxiety Disorders • Genetic vulnerability • Increased activity in the fear circuit of the brain (amygdala) • Decreased functioning of GABA and serotonin, increased norepinephrine activity • Behavioural Inhibition – agitation to new stimuli in infancy • Predictive to a 30% level of development of social anxiety • Neuroticism • Personality trait with a tendency to react with greater than average negative emotion • Twice as likely to develop into an Anxiety Disorder • Cognitive Factors (e.g. attention to cues of threat and low perception of control) • Negative Life events
Common Treatments of Anxiety Disorders • Fewer than 20% of people with Anxiety Disorders receive minimally adequate treatment • Psychological: • Exposure • Cognitive reorganization, rationalizing, etc. • Medical Treatment: Sedatives, tranquilizers and anxiolytics (“to loosen”) • Benzodiaxepines (e.g. Valium, Xanax) GABA. • Cognitive and motor side effects memory lapses and addiction • Antidepressants, tricyclics and SSRIs (e.g. Fluoxetine, Imipraming – Prozac, Zoloft) • Jitteriness, weight gain, high blood pressure, sexual dysfunction
