Definition
Goals, procedures, effects including sustainability
The estimation of the importance, effectiveness, appropriateness, or satisfaction various people experience in relation to particular intervention. |
|
|
Term
|
Definition
Is there a causal relationship between variables? Treatment related to effects.
The degree in which research can be confident that the intervention is what changes behavior. |
|
|
Term
|
Definition
The methodological strategies used to monitor and enhance the reliability and validity of behavioral interventions.
All components are specified, differentiated, and distinct, such as rewards, homework, other practice |
|
|
Term
| Threat to internal validity |
|
Definition
History: events that occur at the same time as interventions can be contributing to changes
Maturation:natural changes can be confused with intervention outcomes |

Definition
| Ongoing measurement to the process of the intervention, making sure the process is correct |

Definition
|
|
Term
|
Definition
| The degree in which the conclusions of the study are valid for members of the population other than study sample. |
|
|
Term
| Treatment integrity or adherence |
|
Definition
Intervention fidelity, implementation reliability
Two methods of checking adherence: direct observation & self-report. |

|
Term
| Experimental question “Demonstrate” |
|
Definition
| Demonstrating the existence of a particular functional relation. “Will the independent variable alter the dependent variable?” |
|
|
Term
| Experimental question “Compare” |
|
Definition
| Comparing independent variables. Two or more independent variables are studied in relation to a fixed set of dependent variables. “Will independent variable 1 or independent variable 2 alter the dependent variable to a greater degree?” “Do the two different interventions produce differential effects on receptive and/or expressive communication?” |
|
|
Term
Experimental question “Component” |
|
Definition
| Pulling apart independent variables. Questions are asking to discover what makes an independent variable work and/or why it works. It is used to conduct efficiency experiments in the sense that they can identify the necessary components of an intervention. “Will removal of one elemental from a multicomponent intervention change the level of the dependent variable?” |
|
|
Term
| Experimental question “Parametric” |
|
Definition
| Identify how behavior changes in relation to parametric variations in some dimension of the independent variable. More thorough understanding of the relation between an intervention and behavior than can be accomplished through asking whether an intervention is effective or not. The parametric analyses are the systematic increase or decrease in the value of some dimension of the independent variable. “What effect will incremental increases in the level of the independent variable have on the dependent variable?” |
|
|
Term
|
Definition
?? Sensitive to how intervention can put on the participants.
- is it harmful?
- is it unethical?
-is it do-able? (can we take away treatment completely?/ can we have a no-treatment group?) |
