Document Summary

Psych 2320b (lec : research on child psychopathology) Research in child psychopathology: background: good research tests specific hypotheses based on theory, hypothesis: prediction about relationship between constructs (i. e. , abstractions that must be operationalized for research) Can"t be proven, only supported (or not) by data. Stat significance doesn"t mean findings are important: clinical versus statistical significance. Can"t be used to argue that variables are unrelated: usually, correlational designs (rather than strictly experimental) are used. Early exposure to abusive parenting and adult antisocial behavior. Research on etiology in psychopathology: two broad design : 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. Identify clinical group w/ historical records: prospective. Research on etiology in psychopathology: genetically informed designs: genes are comprised of dna and reside on chromosomes; can examine genotypes, the phenotype is what we observe, the outcome of interest.
