Chapter 6 Ledford

Question 1

theory of change

Answer 1

conceptual framework that describes why an intervention should result in changes in a target behavior

Question 2

when procedural fidelity is carefully collected, data can be used to

Answer 2

• make decisions about the likelihood of adequate implementation in regular environments
• determine sufficiency of interventions with low fidelity
• explain variability in results

Question 3

implementation fidelity

Answer 3

the extent that experimenters trained implementers as planned

Question 4

procedural fidelity should provide two types of evidence:

Answer 4

• adherence: implemented procedures as planned
• differentiation: implemented different steps in each condition

Question 5

treatment integrity

Answer 5

when data are collected during intervention conditions only

Question 6

procedural fidelity should be collected how frequently?

Answer 6

20-33% of sessions

Question 7

common types of formative analysis

Answer 7

• checklists
• self-reports
• direct-systematic observation

Question 8

summative analysis of procedural fidelity

Answer 8

• increases internal validity
• should occur for each participant in a study
• allows you to document that intervention was implemented as planned and describe conditions that it was effective

Question 9

reporting fidelity

Answer 9

• separately report each procedural step
• report which conditions and which participants fidelity data was collected
• report physical and social conditions in each experimental condition
• condition descriptions should include procedural steps and rules, length and frequency of measurement occasions, and environmental characteristics

Question 10

possible stakeholders in evaluation of social validity

Answer 10

• direct consumers: recipients of intervention
• indirect consumers: people affected by intervention but not direct recipients
• members of immediate community
• members of extended community

Question 11

dimensions of social validity

Answer 11

• were the goals socially important?
• were the procedures socially acceptable?
• are the outcomes socially significant?

Question 12

recommended types of social validity measurement

Answer 12

• normative comparisons
• blind ratings
• measurement of maintenance or sustained use
• participant preference measurement
