Fears in Normal Development
Kerig, et al. 2012, pp. 255-256
Fear is a normal reaction to a threatening event
Fears are common in childhood. Fear and anxiety can be adaptive
Children learn to adapt to, and cope with, fears and anxieties
Anxiety disorders are distinguished from normal fears: Intensity Maladaptiveness Persistence Beyond voluntary control
Anxiety Disorders: Common Features
Characterised by intense, persistent anxiety
Internalised behaviour: suffering is turned inward
Hyperarousal
Achenbach’s (2000) analysis of symptoms in childhood yielded a principle factor of internalizing-externalizing
Prevalence
Anxiety disorders are most common disorders of childhood
Approximately 15-20% of children will develop an anxiety
disorder before adulthood
Australian figures:
7% of children anxiety disorders
(Young Minds Matter study 2013-2014, cited AIHW, 2016)
Wellbeing and Distress in Aboriginal and Torres Strait
Islander peoples:
Greater distress, depression, and anxiety in Aboriginal and
Torres Strait Islander peoples
Dose-response relationship between discrimination and
distress
Gender differences:
Generally, more common in females
Gender ratio increases with age, reaching 1:2 – 1:3 at
adolescence
Comorbidity
High levels of comorbidity
Commonly comorbid with other anxiety disorders
Commonly comorbid with depression
Also comorbid with ADHD, CD
Continuity
Children with anxiety disorders in childhood, likely to have
anxiety (and also depression) in adulthood
70% of children with anxiety disorder, met criteria for anxiety or mood disorder 10 years later
Are Anxiety Disorders and Mood Disorders distinct?
Separate entities or accounted for by an underlying common factor
Maybe it’s both of these things??
If you have multiple anxiety disorders you are more likely to have depression
Clarke and Watson’s (1991) tripartite model
Physiological hyperarousal -> unique anxiety symptoms
Negative affectivity -> will have symptoms of both anx and dep
Low positive affect -> unique depression symptoms
