A prospective study of the relation between scores on the six subscales of the Crown-Crisp experiential index and subsequent incidence of ischaemic heart disease was undertaken among participants in the Northwick Park heart study. Results from 1457 white men aged 40-64 at recruitment showed that phobic anxiety was strongly related to subsequent major ischaemic heart disease (fatal and non-fatal...

Autonomic nervous system arousal should theoretically increase during a phobic reaction. Eleven spider phobics and 11 nonspider phobics viewed spider, seascape, and surgical slides while several physiological responses were continuously recorded. Results indicated that spider phobics showed significantly faster heart rate, greater heart rate variability, and vasoconstriction during spider slide...

Phobic fear is accompanied by intense bodily responses modulated by the amygdala. An amygdala moderated psychophysiological measure related to arousal is electrodermal activity. We evaluated the contributions of electrodermal activity to amygdala-parahippocampal regional cerebral blood flow (rCBF) during phobic memory encoding in subjects with spider or snake phobia. Recognition memory was incr...

The present study examined the relation between maternal anxiety symptoms and child anxiety symptoms and evaluated whether a reporting bias is associated with maternal anxiety. Fifty-seven mother-child pairs participated. All children had features or diagnoses of separation anxiety disorder (SAD), generalized anxiety disorder, and/or social phobia. Measures of maternal symptomatology and child ...

We examined the effects of symptom induction on neural activation in blood-injection-injury (BII) phobia. Nine phobic and 10 non-phobic subjects participated in an fMRI study in which they were presented with disorder-relevant, generally disgust-inducing, generally fear-evoking and neutral pictures. We observed diminished medial prefrontal cortex (MPFC) activity in patients compared to controls...

We tested the hypothesis that an unconscious preattentive perceptual analysis of phobic stimuli is sufficient to elicit human fear responses. Selected snake- and spider-fearful Ss, as well as normal controls, were exposed to pictures of snakes, spiders, flowers, and mushrooms. A separate forced-choice recognition experiment established backward masking conditions that effectively precluded reco...

Epidemiological studies show that anxiety disorders are highly prevalent and an important cause of functional impairment; they constitute the most frequent menial disorders in the community. Phobias are the most common with the highest rates for simple phobia and agoraphobia. Panic disorder (PD) and obsessive-compulsive disorder (OCD) are less frequent (2% lifetime prevalence), and there are di...

BACKGROUND The nation-wide epidemiological survey of psychiatric disorders in term of lifetime prevalence is not adequately known in Iran. The prevalence of lifetime psychiatric disorders was estimated among the population of aged 18 and over on gender, age group, educational level, occupational status, marital status, and residential area. METHODS The subjects were 25,180 individuals selecte...

Interpersonal assessment may provide a clinically useful way to identify subtypes of social phobia. In this study, we examined evidence for interpersonal subtypes in a sample of 77 socially phobic outpatients. A cluster analysis based on the dimensions of dominance and love on the Inventory of Interpersonal Problems-Circumplex Scales (Alden, Wiggins, & Pincus, 1990) found 2 interpersonal subtyp...

The less disabling phobias do not normally present a problem in that the stimulus may be avoided. This would also apply to hospital phobia until an acute medical or surgical problem might arise, when avoidance could constitute a direct threat to life. Although phobic illness is a common problem the small number of cases of hospital phobia recorded may represent the tip of the iceberg beneath wh...
