Four participant dyads completed the baseline evaluations only, thus no postintervention data were obtained on them. One dyad within the extended intervention group withdrew due to the burden of study visits, and the remaining three dyads were lost to follow‐up due to lack of feasibility of the site to deliver the intervention.
Magnitude score = frequency × severity.
n = 18 or 19, except for LV‐VFQ‐20 (n = 11).
n = 15, except for LV‐VFQ‐20 (n = 10) and GSE (n = 14).
