Definitions of Dependent and Independent Variables.

Note. We hypothesized that low maternal education, prenatal substance use, social isolation, and relationship distress could adversely impact child anxiety. These variables were unavailable in the main administrative databases. Thus, we abstracted them from the Families First screen data that are collected by Healthy Child Manitoba. The Families First screen is conducted by public health nurses during a home visit scheduled shortly after delivery and is intended to identify biological and social risk factors as well as provide education and links to community support (http://www.gov.mb.ca/healthychild/familiesfirst/). Some data (e.g., education) on the Families First screen are missing if they were not collected at the time of the public health nurse visit.
aManitoba Jobs and the Economy currently administers the income assistance data; formerly Manitoba Family Services.
