Objectives. To describe the characteristics of homeless and low-income
preschool-aged children, and to identify family and environmental det
erminants of their behavior. Methods. An unmatched case-control design
was used to recruit a sample of sheltered homeless families and a com
parison group of low-income housed families who were never homeless in
Worcester, Massachusetts. Seventy-seven sheltered homeless and 90 low
-income housed mothers with preschool-age children were assessed using
a comprehensive interview protocol. Information about mothers' housin
g, income, service use, parenting practices, and children's father was
obtained. Data about children's background, health, and life events w
ere included. Standardized instruments were administered to assess mot
hers' mental health and their children's behavior. Comparisons of home
less and low-income housed families were used to describe the sample o
f 167 preschoolers. Multiple linear regression was used to examine the
association of various stressors, such as homelessness, and family fa
ctors with their behavior. Results. Although homeless preschoolers wer
e significantly more likely to have experienced stressful life events,
undergone a fare and protection investigation, and been placed in fos
ter care when compared with low income preschoolers, differences in ad
verse behaviors were minimal. Although homeless children scored higher
than housed children on the internalizing, externalizing, and total p
roblem score on the Child Behavior Checklist (CBCL) (52.5 vs 49.9, 54.
8 vs 51.2, and 54.4 vs 51.1, respectively), approximately equal number
s of children from both groups scored in the clinical range. With rega
rd to determinants of behavior, mothers' emotional status was one of t
he strongest independent predictors of negative behavioral outcomes on
both subscales. Foster care placement and death of a child's friend w
ere predictors of adverse internalizing behavioral outcomes on the CBC
L. After controlling for housing status, parenting practices, child's
age, child's history of physical abuse, and specific life stressors pr
edicted adverse externalizing behavioral outcomes. For both subscales,
housing status and behavior were only marginally associated in the mu
ltivariate model. Conclusions. Both homeless and low-income children e
xperienced significant adversity in their lives, with homeless prescho
ol children facing more stress. However, differences in behavior as me
asured by the CBCL were minimal. Mothers' emotional status, in additio
n to various stressors, strongly predict children's negative outcomes
for both CBCL subscales. These findings emphasize the importance of pr
eventive family-oriented interventions that address the needs of presc
hoolers and their mothers.
