Study Notes
Component Analysis
- Involves evaluating a complete treatment package to identify which elements effectively maintain behavior.
- Enhances social validity by pinpointing ineffective aspects of treatment that require more effort.
- Focuses on the functional relationship between the dependent variable (behavior) and the independent variable (treatment).
Parametric Analysis
- Aims to determine the optimal level of an independent variable to achieve desired behavioral outcomes.
- Involves comparing different intensities, durations, or characteristics of the same treatment component.
- Addresses relationships between varying degrees of treatment and their effects on behavior for specific individuals or groups.
Comparative Analysis
- Compares two or more different treatments applied separately, allowing for differentiation in effectiveness.
- Similar to reversal designs, it helps determine which treatment yields better results based on observed behaviors.
Methods of Component Analysis
- Add-in Method: Gradually integrates components of a treatment package while monitoring behavioral changes. Determines necessity and sufficiency of each component.
- Drop-out Method: Begins with the full treatment package and removes components systematically to identify essential elements. A critical component is deemed necessary if its removal leads to decreased effectiveness.
Interaction Between Components
- Additive Effects: Each component must function independently to ensure accurate evaluation.
- Multiplicative Interaction: Actions of one component may depend on or amplify the effects of another component, highlighting interdependence.
Necessary vs. Sufficient Components
- Necessary Components: Must be present for the treatment to work effectively on target behavior.
- Sufficient Components: Refers to the level of a component needed for the treatment to be effective.
Behavioral and Sequence Effects
- Component analysis can uncover immediate improvements in target behavior or subsequent effects due to the order of component implementation.
Design Options
- Various experimental designs can be used for component analysis, including multiple baselines (MB), reversals, and alternating treatments. An effective approach uses combinations to minimize confounding variables.
Ideal Designs
- An add-in reversal or alternating treatment design is the most powerful as it reduces risks of confounds from combining treatment effects.
Clinical Relevance
- Component analysis should be conducted when therapy is costly or demanding, and for understanding treatment effectiveness and underlying mechanisms.
Case Examples
- Comparative Example: Alternating treatments of response interruption plus redirection against non-contingent reinforcement (NCR) for a child displaying stereotypy.
- Component Example: Implementing differential reinforcement followed by a combination treatment to increase compliance.
- Parametric Example: Systematically testing the effects of different monetary rewards on improving exercise habits.
