text: Yo, check it out, I'm 'bout to drop some knowledge,
  Research on behavior problems, let's acknowledge.
  In preschool children, we peeped the prevalence,
  The course and correlates, we got the evidence.
  
  Epidemiological studies, they were prospective,
  Follow-ups on clinical samples, yo, effective.
  Externalizing problems, they tend to persist,
  Identified early, can't resist.
  
  Parental behavior, inconsistent and negative,
  Family adversity, yo, that's the narrative.
  They're associated with problems in early years,
  Predictin' their persistence, causin' fears.
  
  We takin' a developmental stance,
  Integratin' research on optimal parent-child dance.
  The severity of problems at the start,
  And family context, they play a part.
  
  Different outcomes, yo, they're related,
  Based on the problems and how they're created.
  So, let's understand the roots and connections,
  To help these kids and make positive corrections.
