Question 1

Barclay-Goddard, R., Lix, L.M., Tate, R., Weinberg, L., & Mayo, N.E. (2011). Health-related quality of life after stroke: Does the response shift occur in self-perceived physical function? Archives of Physical Medicine and Rehabilitation, 92(11), 1762-1769. https://www.ncbi.nlm.nih.gov/pubmed/22032211

Question 2

The authors were aiming to determine the existence of a response shift in a post-stroke model, which affected the self-perception of health-related quality of life (HRQL).

Question 3

The authors stated that there are generally unexpected changes in personal perceptions and meanings of HRQL after recovery from chronic conditions due to experiences and expectations. They were interested in assessing the response shift among recovered stroke patients.

Question 4

It was expected that no response shift would occur in the physical function of post-stroke patients for more than one year.

Question 5

A total of 677 people participated in the study, with 55% being men. Another 67 individuals were approached but refused to participate. The mean age of the participants was 68 years. Their post-stroke period was 1, 3, 6, and 12 months.

Question 6

The participants’ response shift was detected using a three-component model, which was developed by the researchers. The model was a modification of Oort’s method, which is a 4-phase method that used structural equation modeling (SEM) for response shift detection.

Question 7

The secondary data from an observational study was analyzed for each sample of the participants with different post-stroke periods. The model was then used to gather information about critical physical function characteristics apart from pain. The internal validation phase was done through comparison using two estimation methods known as maximum likelihood estimation (MLE) and full information maximum likelihood (FIML).

Question 8

Upon the analysis of data, the study found the existence of response shifts of both reprioritization and recalibration types in physical activities, such as hand function and walking.

Question 9

The results of the study are crucial in informing the evaluation of physical functions in clinical settings. Future directions based on the survey can include research to evaluate models with both performance-based and self-perceived measures.
