PSYB45H3 Chapter Notes - Chapter 22: Dependent And Independent Variables, Developmental Disability, Internal Validity
Document Summary
A minimal behavior modification program has 4 phases: Screening phase: for clarifying the problem and determining who should treat it. Assessment or baseline phase: for determining the causes of the problem behavior and its initial level prior to the program. Treatment phase: in which the intervention strategy is initiated. Follow-up phase: for evaluating the persistence of the desirable behavioral changes following termination of the program. Dependent variable the measure of behavior; independent variable the treatment or the intervention. A study that has internal validity is convincingly demonstrated that the independent variable caused the observed change in the dependent variable. A study has external validity when the finding can be generalized to other behaviors, individuals, settings, or treatments. Reversal-replication design: experiment design consisting of a baseline phase followed by a treatment phase, followed by a reversal back to baseline conditions and followed by a replication of the treatment phase.
