Week 3.2.3: Predicting the Transition to Psychosis Flashcards
Refers to individuals who show early signs or symptoms that may indicate a higher likelihood of developing psychosis in the future.
Clinical High Risk for Psychosis
Instruments or tests used to measure psychological variables such as personality traits, mental health conditions, or cognitive abilities.
Psychometric Tools
A specific psychometric tool used to identify individuals at high risk of developing psychosis.
CAARMS (Comprehensive Assessment of At-Risk Mental States)
The consistency of a psychometric instrument in measuring what it is supposed to measure. If different raters use the instrument and get similar results, it is considered reliable.
Example: If multiple clinicians use CAARMS to assess the same individual and all conclude that the person is at high risk for psychosis, CAARMS is reliable.
Reliability
The accuracy of a psychometric instrument in identifying the true positives, i.e., those who will actually develop psychosis.
Example: If CAARMS correctly identifies individuals who later develop psychosis, it is considered valid.
Validity
A statistical measure of inter-rater agreement for qualitative (categorical) items. It accounts for the agreement occurring by chance.
Example: If two clinicians independently assess the same patient using CAARMS and their diagnoses agree 80% of the time, Cohen’s kappa would be 0.8.
Cohen’s Kappa
Criteria used by the CAARMS tool to identify individuals at high risk of developing psychosis. These criteria include various symptoms and risk factors.
CAARMS Intake Criteria
A statistical analysis that combines the results of multiple scientific studies to identify overall trends and outcomes.
Meta-Analysis
Mental health conditions like major depressive disorder or bipolar disorder that include episodes of psychosis
Mood Disorders with Psychosis
A range of disorders that include schizophrenia and other related conditions.
These disorders affect a person’s ability to think clearly, manage emotions, and interact with others
Schizophrenia Spectrum Disorders
A mental health condition where an individual loses touch with reality, experiencing symptoms like hallucinations and delusions.
Psychosis
Short-lived psychotic episodes lasting less than seven days and resolving without antipsychotic medication.
High risk of developing psychosis, up to 40-50% within two years
Brief Limited Intermittent Psychotic Symptoms (BLIPS)
Symptoms that are psychotic in nature but less severe and more transient
Intermediate risk of developing psychosis, about 20% within two years
Attenuated Psychotic Symptoms (APS)
Genetic vulnerability combined with a history of functional deterioration
Genetic Risk and Deterioration Syndrome (GRD)
What are the CAARMS subgroups?
- Brief Limited Intermittent Psychotic Symptoms (BLIPS)
- Attenuated Psychotic Symptoms (APS)
- Genetic Risk and Deterioration Syndrome (GRD)
The initial occurrence of schizophrenia symptoms, such as hallucinations, delusions, and disorganized thinking.
Treatment: Typically involves antipsychotic medications and psychosocial interventions
First Episode Schizophrenia
Significant reduction or disappearance of schizophrenia symptoms
Symptomatic Remission
Improvement in daily functioning, such as social interactions and occupational performance
Functional Remission
