In the assessments, a variety of manifestations of parental deviance and problems, including parental substance abuse, the father's behavioral problems, and parental anxiety-depression, were associated with myriad problem behaviors of their boys at a young age, but were less associated with problem behaviors as the youths grew older. Other macrofactors, including bad neighborhoods, unemployed mothers, large families, and African-American ethnicity, were associated with unfavorable outcomes. The authors report three key elements as most relevant for the development of problem behaviors: poor impulse control, attention problems, and the lack of guilt feelings.
