Classifying Psychological Disorders
Diagnostic and Statistical Manual (DSM) Includes information on medical conditions, psychosocial problems and global assessment of functioning Concerns about reliability and validity of the standards Predictive validity predictive validity – in this usage, the extent to which a diagnosis permits one to predict the course of a disorder and the type of treatment that may be of help
13
Prevalence of Psychological Disorders

57
Explaining Schizophrenia
Biological Brain differences Heredity Complications during pregnancy and birth Birth during winter Dopamine theory of schizophrenia Brain disorder – Focus on amount of gray matter, size of ventricles (hollow spaces), activity levels in the rain, and brain chemistry Dopamine theory of schizophrenia suggests that people with schizophrenia over utilize dopamine

Average Rates of Loss of Gray Matter Among Normal Adolescents and Adolescents Diagnosed with Schizophrenia Figure 12.2: Average Rates of Loss of Gray Matter Among Normal Adolescents and Adolescents Diagnosed with Schizophrenia - High-resolution MRI scans show rates of gray matter loss in normal 13- to 18-year-olds and among adolescents of the same age diagnosed with schizophrenia. Maps of brain changes reveal profound, progressive loss in schizophrenia (right). Loss also occurs in normal adolescents (left), but at a slower rate.

Explaining Schizophrenia
Biopsychosocial perspective Genetic predisposition Genetic vulnerability interacts with other factors
61
The Biopsychosocial Model of Schizophrenia
Figure 12.4: The Biopsychosocial Model of Schizophrenia - According to the biopsychosocial model of schizophrenia, people with a genetic vulnerability to the disorder experience increased risk for schizophrenia when they encounter problems such as viral infections, birth complications, stress, and poor parenting. People without the genetic vulnerability would not develop schizophrenia despite such problems.
