x: Health status was measured using a single item, and scale reliability could not be calculated.
Spearman's rank order correlations (0.00–0.29 weak; 0.30–0.69 moderate; 0.70–1.00 strong).
aKR‐20 was calculated for dichotomous variables, Cronbach's alpha for all other variables.
* P<.05; ** P<.01; *** P<.001.
