Phobia Flashcards
Eysenck
66% of patients w/1 anx disorder also diagnosed w/another anx disorder
Hiller et al
Reported satisfactory to excellent diagnostic agreement in a test-retest study using the MDC
Vasey & Dadds
Treatment success of anx disorders was unrelated to the original diagnosis of a specific phobia. Same treatments worked equally well so no benefit in making a specific diagnosis of 1 kind of anx disorder
Mattick & Clarke
Their Social Phobia Scale correlated well w/other standard measures (varying btwn +.54 n+.69)
Beidel et al
SPAI doesn’t correlate w/behaviours related to other anx disorders
Fyer et al
Probands had 3x as many relatives who also experienced phobias as normal controls
Solymon et al
45% of phobic patients had at least 1 relative w/the disorder compared to a rate of 17% for non-phobic controls
Ost
64% blood phobics had at least 1 relative w/the same disorder
Togersen
Compared MZ n same sex DZ twin pairs where 1 twin has an anx disorder w/panic attacks n such disorders were 5x more frequent in MZ twin pairs
Marks & Nesse
Modern day phobias are exaggeration of ancient fears
Seligman
Biological preparedness!!
Marks
When an infant sees a stranger, they first look at their mother to gauge here response. Fear in the mother is likely to produce a fearful reaction from the infant
Mineka et al
Rhesus monkeys rapidly develop a fear of snakes if they see another monkey showing fear towards a snake but same reaction doesn’t occur if another monkey shows fear towards a flower
Kagan
Identified an infant temperamental type ‘behavioural inhibition’- infants who tend to withdraw from unfamiliar ppl> had a genetic basis
Biederman et al
Support!! Behavioural inhibition to unfamiliar things/situations is genetically based b a risk factor for anx disorders
Tiihonen et al
Found significantly lower no. of dopamine up-take in patients w/social phobia compared to normal controls
Ohman & Soares
Support for prepotency effects!! Gr8r GSR response to ‘masked’ pics of feared animals
McNally
Evidence for enhanced resistance of extinction of fear responses to prepared stimuli but not for rapid inquisition
Merckelbach et al
Most clinical phobias in their sample rated as ‘non’ prepared, rather than prepared
Brown et al
Phobia more common among African American than white, even when socioeconomic factors controlled
Davey
Expectancy biases- explains certain anomalous data e.g. the lack of rapid acquisition of phobias n the acquisition of ‘modern’ phobias
