Research Methods in Psychopathology: Correlation
Desc: Study of the relationship between two or more variables; measured as they exist in nature; Pro: Used due to ethical issues, Often in epidemiologist to study prevalence, incidence, & risk factors, Often in behav. genetics to study heritability of mental disorder; Con: No causality because of directionality and third-variable.
Research Methods in Psychopathology: Experiment
Desc: Includes independent/dependent variables, pref. 1+ control, & random assign.; Pro: Can determine causality, Often used in treatment, Use in analogue studies of risk for mental illness; Con: Single-case common but limited external validity.
Def: Correlation Coefficient
