Two-sided Fisher’s exact test, P < .0001. Cramér's V = 0.48. The strength of the association (effect size) was measured by Cramér's V, which has values ranging from 0 to 1: low association (V = 0.1–0.3), moderate association (V = 0.3–0.5), and high association (V > 0.5).²² Cohen's W is equivalent to Cramér's V in our study with 3 × 2 contingency table. The sample size was 115 dyads; 1 dyad had missing data.

^aRationale for recoding the data at 3 levels of agreement to generate a new variable is illustrated by the small number of cells for each situation.

^bDyadic “do not know” responses were treated as no agreement/no agreement, that is, low agreement.
