Q

Allocation Concealment

A

The person who determine if a subject was eligible for inclusion in the trail was unaware of which group the subject would be allocated to when this decision was made

Q

Pragmatic Clinical Trial

A

Has the following characteristics:
1. Minimal exclusion criteria
2. Looser restrictions on recruitment
3. Treatment is less rigidly controlled, better mimics actual clinical practice
4. Control group receives standard of care

Q

Crossover/Repeated Measures Design

A

each experimental unit is given each of the different treatment levels over the course of the experiment.

Washout Period: time between interventions that eliminates effect of intervention on outcome measure

16
Q

One Group Pre-Test/Post-Test Design

A

Can be used when
1. Previous research has documented behavior of control group
2. time period is short enough to minimize effect of other variables

17
Q

Repeated Measures Design

A

Similar to one group pre-test/post-test, but multiple post tests administered
no control group

18
Q

Interrupted Time Series Design

A

multiple measurements both before and after treatment administered
multiple pre-tests help minimize time as a potential confounding variable

19
Q

Non-equivalent pre-test/post test with control group

A

Treatment and control groups, but no randomization
groups may already be intact or participants may choose their group

20
Q

Non Equivalent Post Test Only with Control Group

A

Same as non-equivalent pre-test/post test with control group, no pre-tests administered

21
Q

Historical Control Group

A

same as non-equivalent pre test/post test, but control group is from historical data collected at a previous time

22
Q

Single Subject Designs

A

group research can hide individual difference and generate results that do not represent the behavior of any individual

can also serve as pre-cursor to RCTs in order to better understand the effect of the treatment on the outcome

each participant receives a treatment and serves as their own control

23
Q

Single Subject Design Examples

A

ABA or ABAB Designs
Multiple Baseline
Multiple Treatment

24
Q

ABA or ABAB Designs

A

A is the baseline, B is the intervention

data collected at baseline, during intervention, after intervention is removed, and possibly again during intervention

25
Q

Multiple Treament Design

A

A = Baseline, B = Intervention 1, C=Intervention 2

Data collected at baseline, during intervention 1, after the intervention is removed, and again during intervention 2

26
Q

Observational Study Designs

A

Case-Control
Cohort

27
Q

Descriptive Study Designs

A

Cross Sectional
Case Series
Case Study

28
Q

Types of Experimental Designs

A

Pre-Test/Post Test
Post-Test Only
Factorial Design
Crossover
