Adherence of participants in a long-term clinical trial is necessary to assure validity
of findings. This article examines adherence differences between single-parent
and two-parent families in the Childhood Asthma Management Program (CAMP).
Adherence was defined as the percentage of completed daily diary cards and
scheduled study visits during the course of the trial. Logistic regression and ordinal
logistic regression analyses were used. Children from single-parent families had a
lower percentage of completed diary cards (72% vs. 84%) than two-parent families.
Single-parent families were also more likely to reschedule visits (62% vs. 45%) and
miss more clinic visits (23% vs. 17%) than two-parent families. Suggestions are
given for study coordinators to assist participants in completing a long-term clinical
trial. Many suggestions may be adapted for nurses in inpatient or outpatient settings
for assisting parents of patients with chronic diseases.
