why surface behaviour isn’t enough to describe psychological disorders
atypical behaviours don’t always equate to psychological disorders, especially if there’s another reason (e.g. crying a lot for hours on end may not equate to depression, especially if someone has recently lost a loved one)
mental disorders
persistent disturbance or dysfunction in behaviour, thoughts, or emotions that causes significant distress or impairment
two models for psychological disorders
- medical model: psychological disorders are illnesses with biological causes
- biopsychosocial model: psychological disorders are illnesses with biological (internal), psychological (external), and social (relational) causes
psychopathology
the scientific study of mental disorders
overpathologizing
attributing diverse or atypical behaviours or thoughts to psychological disorders, particularly when diagnostic criteria isn’t met (e.g. thinking that someone who’s super anal has OCD)
diagnostic criteria
a set of symptoms, behaviours, or characteristics that must be present in order to diagnose an individual with a disorder
instruments clinicians can use to diagnose psychological disorders
- questionnaires and interviews
- observation of behaviour
- patient history
- neuroimaging
the DSM-5
- the Diagnostic and Statistical Manual of Mental Disorders (in its 5th edition)
- published by the American Psychiatric Association; used predominantly in North America
- uses a biopsychosocial model
- used by clinicians to diagnose psychological disorders
the five pieces of information about each disorder that the DSM-5 includes
- diagnostic criteria: symptoms
- onset: the age/period when symptoms first appear
- prognosis: the likely trajectory of a disorder (i.e. fixed period vs. lifelong)
- risk factors/etiology: risk factors increase the likelihood of having the disorder (often known), and etiology causes the disorder (often not known)
- comorbidities: other disorders that are likely to co-occur
the three diagnostic criteria most DSM-5 disorders have in common
- causes significant distress/affects functioning
- cannot be attributed to substance use or another medical condition
- cannot be better described by another DSM diagnosis
the diathesis-stress model
the risk of a disorder, personality of a person, and life circumstances combine to lead to the disorder
criticisms of the DSM-5
- can lead to overpathologizing
- follows a binary system (either you have the disorder or not), but many disorders have spectrums
fear vs. anxiety
- fear is a response to a specific, present stressor; it’s often adaptive, increasing fitness
- anxiety is the fear of a potential stressor (fear of fear); it’s often maladaptive, decreasing fitness
Fear and anxiety are both ________, but anxiety that interferes with normal functioning is ________.
adaptive, maladaptive
________% of Canadians will experience anxiety, but only ________% are ever diagnosed.
30%, 5%
generalized anxiety disorder (GAD)
an anxiety disorder in which worries are not focused on any specific threat
diagnostic criteria of generalized anxiety disorder
- Excessive anxiety and worry, occuring more often than not for at least 6 months, about more than one stressor
- Difficult to control the worry
- Three or more of these symptoms:
- restlessness
- fatigue
- concentration deficiency
- irritability
- muscle tension (i.e. headaches)
- sleep disturbance
- Causes significant distress/affects functioning
- Cannot be attributed to substance use or another condition
- Cannot be better described by another DSM diagnosis
onset of generalized anxiety disorder
- often diagnosed around 30 years old
- constant anxiety throughout the lifespan (doesn’t increase/decrease with age); content of worries change
prognosis of generalized anxiety disorder
- severity of symptoms waxes and wanes across a lifespan
- full remission is rare
phobic disorders
- a specific type of anxiety disorder characterized by an excessive fear of specific objects or situations
- the irrationality of the fear is often recognized, but uncontrollable (e.g. you know a spider can’t hurt you, but you’re still scared of it)
specific types of phobias
- animals (e.g. spiders, snakes)
- natural environments (e.g. earthquakes, darkness)
- situations (e.g. elevators, enclosed spaces)
- medical events (e.g. blood, injections)
- costumed characters (e.g. clowns, dolls)
- loud noises
- choking
social anxiety disorder
- a maladaptive fear of public humiliation
- may have a “performance-only” specifier (i.e. stage fright, but can engage with others)
why phobic disorders are so common
- preparedness theory: evolutionarily adaptive to fear certain stimuli
- overdevelopment of said fears in individuals leads to phobic disorders
