This study examined factors associated with the utilization of universally
available school-based parent training. In a randomly selected, prospective
ly screened, unreferred community sample of 1,498 5- to g-pear-olds, 28% to
46% of families of children with high parent-reported externalizing proble
ms enrolled. Externalizing problems, first-child status, and a high school
education were associated with increased enrollment. Single-parent status,
immigrant background, and limited extracurricular child activities were ass
ociated with lower enrollment. Economic disadvantage, stress, family dysfun
ction, and parental depressive symptoms were not associated with participat
ion. Most families attributed nonparticipation to busy personal schedules,
inconvenient times, and logistical difficulties.
