  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 • Cost-Benefit Analysis
