1. Research Methods in Behavior Change Programs
Chapter 11

2. Accuracy of Data: Training and Monitoring Observers
Other procedures can enhance accuracy
let observers know their accuracy will be checked
use interobserver reliability procedures in training
use the procedures to evaluate the accuracy of self-monitoring

3. Sources of Data Inaccuracies
Measure outcomes of behavior
Rating scale questions & labels not clearly defined
Self-report data may be flawed – poor memory
Reactivity effects
Poor operational definition
Observers may not be trained or motivated to record accurately

4. Accuracy of Data: Increasing Reliability
Use more than one independent observer
Check interobserver reliability of observers
Train and monitor observers

5. Intrasubject Research
AB Designs
ABAB (Reversal) Designs
Multiple Baseline Designs
Across Behaviors
Across Situations
Across Individuals
Changing Criterion Designs
Alternating Treatment Designs

6. Reversal Designs

7. Multiple Baselines Across Behaviors

8. Alternating-Treatment Design

9. Group Designs Within-Subjects Designs Between-Subjects Designs
independent and dependent variables
random assignment
quasi-experimental designs

10. Evaluating Behavior Change
Follow-Up Assessment
Change behavior that is significant to the individual’s functioning
