Document Summary

Research in child psychopathology: research on etiology (today, research on treatment (jan 29th) Statistical significance doesn"t mean findings are important. Opposite as typical way you"d think: two broad, basic design distinctions typically seen in psychopathology research, cross-sectional. All data collected at same point in time: longitudinal, cross-sectional vs. longitudinal designs, cross-sectional designs most common, easy to implement. Cannot infer causality: longitudinal designs attempt to address causality. If iv precedes dv, causality is supported but not established. Follow clinical group over time: follow-back. Look at records and past yourself and then make conclusions: prospective gold standard. Research in etiology on psychopathology: genetically informed designs: genes are comprised of dna and reside on chromosomes, the phenotype is what we observe, the outcome of interest, adhd, major depression, hair/eye colour. Disorders may influence process: prenatal environment problem, twin studies use mz and dz twins to estimate heritability of a disorder.
