Psychometric properties of the Chinese version of the recovery locus of control (RLOC) Scale among patients with myocardial infarction.

The sample came from one tertiary hospital and was a convenience sample, so it may not apply to county hospitals or other MI populations. Data were collected only once, before discharge, so the researchers could not check whether the scale gives the same result over time. Face validity and convergent validity were not tested, so the scale has not been checked against other similar measures. The authors noted no significant relationships between patient characteristics and total scores, which they say might be sampling error. It was tested only in patients ready for discharge who could read and speak Chinese, not in people with cognitive impairment or language barriers.

The supplied article text does not include a conflict of interest statement; the publication type notes non-U.S. government research support.

Do not read this as proof that using the scale improves recovery or reduces readmission. The study tested only whether the Chinese version measured recovery beliefs consistently; it did not test any care plan or patient outcome.
