Document Summary

Physical vs. experiential aetiology - linear (on test?) Diagnosis (or none, or minor, or due to pre-existing factors) - dsm iv or 5 (revisions use decimals) Hierarchy of causation biopsychosocial bio = brain/neuropsychology (cns) / hyper/hypo arousal (ans) down to synapses trauma causes brain damage directly or it impacts the brain indirectly. Length of trauma reaction (high blood pressure) indicates recovery (higher at er, poorer outcome) psycho = coping, personality, sense of free will, hope vs. catastrophising social = support from family, insurance/wsib, friends, active social life. Exposure = traumatic story, repeated until they get habituated to it. Dsm has some good and some poor reliability. Construct validity: extent a test measures what it is supposed to and not something else. Predictive validity: extent a test predicts the behaviour it"s supposed to measure. Content validity: extent a test assesses all aspects of a phenomenon. Mmpi: lie scale - tendency to create a positive image (or negative?)
