Week 3 The Research Method in Behavior Modification 1. Measure the dependent variable (this would be the target behavior) a. Skinner was the first to do this 2. Manipulate the independent variable (environmental events/treatment) and demonstrate a change in target behavior 3. Replicate – because you must develop a cause and effect relationship The Purpose of Research Design in Behavior Modification : to evaluate the effectiveness of treatment by demonstrating a functional relationship between environmental event and behavior Functional relationship : a relationship between a behavior and an environmental event in which the occurrence of the behavior is controlled by the occurrence of the environmental event Research Designs A-B design: A= baseline; B=treatment; one baseline and one treatment phase o Not a true research design; no replication o Doesn’t demonstrate a functional relationship o Used in clinical practice; self-management projects ABAB Reversal Design: baseline and treatment phases are implemented twice for one behavior of one subject o Not always ethical; shouldn’t always go back to baseline (violent baseline) Things to consider: o Is it ethical? o Will behavior reverse? o Is it possible? Multiple Baseline Designs: Demonstrate a functional relationship; treatment is replicated across 2 or more baselines Across-subjects Design: 2 or more subjects w/ same target behavior o Treatment is staggered across subjects (over time) Across Behaviors: 2 or more of same subject o Treatment is staggered across behaviors Across-settings design o 2 or more settings with same target behavior of same subject o Treatment is staggered across settings Alternating treatments design o Compare baseline and treatment condition or 2 treatment conditions Week 3 o Conditions are alternated rapidly (every other day) and staggered with each Changing Criterion design o Doing less or more of something every day o Multiple performance criteria in treatment phase
