Multidimensional Integrative Approach to Psychopathology
Multidimensional Models of Psychopathology Social Influences Biological Influences Behavioral Influences Cognitive & Emotional Influences
Genes and Psychopathology • No single gene • Inherit Predispositions, not Psychological Disorders
Gene-Environment Interactions • Diathesis-Stress Model • Inherit Tendencies (Diathesis) • Tendencies Activated (Stress) • Schizophrenia, Substance Abuse, Blood-Injection-Injury Phobias
Neuroscience Perspective • Primarily looks at central nervous system (brain and spinal cord) and its “communicators”
Neurotransmitters: The Chemical Messengers • Norepinephrine (noradrenaline) • Serotonin • Dopamine • Gamma Aminobutyric Acid (GABA) • Major Neurotransmitters in Psychopathology
Neurotransmitter Functions • Dopamine • Pleasure-Seeking • Schizophrenia (too much) • Parkinson’s Disease (too little) • L-DOPA (Agonist)
Behavioral Genetics & Gene-Environment Interactions • Pedigree Studies • “Family Tree” • Twin Studies • Identical vs Fraternal • Adoption Studies • More Compelling Approach
Examples of cognitive-behavioral influences Depressogenic thought patterns Reinforcement patterns (e.g., alcoholism, phobias) Conduct disorder developing into anti-social personality disorder (lack of punishment? brain-environment interaction?)
Social-Interpersonal Influences • Lack of Social Support • Depression and Suicide • Illness and Suppressed Immune Function • Variety of Other Disorders • Increasing Social Support Helps • Interpersonal Psychotherapy (IPT) • Support groups / Group therapy
