Evidence-Based Practice and Research in Occupational Therapy

A.A test does not contain a comprehensive set of items to measure the skill/behavior being tested.

B.The research cannot verify if the independent variable caused the changes in the outcome.

C.The dependent variable was not measured.D.A test cannot differentiate children who

have a particular delay from those who do not.

A researcher is studying the effect of GFCF Diet on children with autism. Patients are randomly assigned by the researcher to receive either a GFCF diet or a regular diet. The parents are informed that their children are being studied, but they do not know which treatment they are getting. Improvement is based upon the increase or decrease of injurious behaviors.

A. Double blind because the parents do not know which treatment they are getting and which is more effective.

B. Double blind because neither the researcher nor the parents know what treatment each person is getting.

C. Single blind because the patients do not know what treatment they are getting but the researcher does.

D. None of the above.

A patient who has Traumatic Brain Injury (TBI) was recommended to receive therapy services to address serious behavioral problems. An occupational therapist (OT) introduced a behavioral program to be implemented during OT and speech therapy (ST) sessions. The graph on the next slide represents the results.

A. The treatment appears to improve the client’s behaviors.

B. The treatment did not improve the behaviors.

C. The treatment had no effect on the behaviors.

D. Further investigation on the effect of treatment on behavior is necessary.

A. Involves the use of 2 individuals, A and B

B. Has 2 baseline periodsC. Depends on manipulating A and

measuring BD. Involves correlating AA with BB

A. Case-controlled studies involve a group with a condition and a group without that condition.

B. Cohort studies involve a group with a condition and a group without that condition.

C. Case-controlled studies are used in establishing the effectiveness of an intervention in a treatment group as compared to a control group.

D. None of the above.
