Behavior Therapy for a 19-Month-Old Child

Yes, behavior therapy is recommended for a 19-month-old child with disruptive behaviors, as behavioral parent training does not require a specific diagnosis and demonstrates large, sustained effects even in very young children. 1, 2

Why Behavior Therapy Works at This Age

Behavioral parent training is the appropriate first-line intervention for toddlers with behavioral concerns because it targets the parent-child interaction patterns that shape behavior, regardless of whether formal diagnostic criteria are met. 1, 2

  • The evidence explicitly states that "behavior therapy does not require a specific diagnosis, and many of the efficacy studies have included children without specific mental behavioral disorders." 1
  • Meta-analytic data demonstrates that psychosocial treatments for early disruptive behavior problems show large effect sizes (Hedges' g = 0.82 overall, 0.88 for behavioral treatments specifically). 1, 2
  • Treatment effects are robust and sustained at follow-up evaluations, falling within the medium to large range even months after treatment completion. 1

What Behavioral Interventions Look Like at 19 Months

Parent training programs should focus on reshaping the physical and social environment through specific techniques that modify toddler behavior. 1, 2

The core components include:

  • Training parents to provide positive reinforcement when the child demonstrates desired behaviors (e.g., praise, attention, rewards). 1, 2
  • Teaching planned ignoring as an active strategy to reduce disruptive behaviors, or using praising and ignoring in combination. 1, 2
  • Establishing consistent consequences when the child fails to meet behavioral expectations, applied immediately and predictably. 1, 2
  • Gradually increasing expectations as tasks are mastered to shape increasingly complex behaviors over time. 1

Evidence-Based Programs to Consider

The strongest evidence supports specific manualized programs: Parent-Child Interaction Therapy (PCIT), Incredible Years, Helping the Noncompliant Child, and Triple P–Positive Parenting Program. 1, 2

  • These programs have been studied in children as young as 2 years old and demonstrate effectiveness across the preschool age range. 1
  • Both individual and group delivery formats work equally well, making group formats preferable for cost-effectiveness. 1, 2
  • Treatment length does not significantly moderate outcomes, allowing flexibility in session number based on family needs. 1, 2

Age-Specific Considerations

Treatment effects are actually larger in samples of older youth within the early childhood range, but 19-month-olds still benefit substantially from behavioral interventions. 1

  • Age moderated treatment response in meta-analyses, with treatments showing larger effects in samples of older children within the preschool range. 1
  • However, the overall effect size remains in the large range even for the youngest children studied. 1
  • The toddler period is an ideal time to intervene because parent-child interaction patterns are still highly malleable. 2

Critical Pitfalls to Avoid

Never consider medication for a 19-month-old with behavioral concerns—this child is far below the minimum age (4 years) at which medication might even be considered, and only after behavioral interventions have failed. 1, 2

  • Medication is only appropriate for preschool-aged children 4-5 years old, and only as a second-line treatment after behavioral interventions fail to provide significant improvement. 1
  • At 19 months, the risks of medication far outweigh any potential benefits, and no controlled efficacy data exist for children this young. 2
  • Avoid non-behavioral approaches (family systems therapy, nondirective counseling) as they demonstrate only small-to-medium effects compared to behavioral treatments. 1, 2

What to Expect from Treatment

Behavioral parent training requires consistent implementation over several months, with ongoing adherence necessary to maintain effects. 1

  • Unlike medication which stops working when discontinued, behavioral interventions require continued adherence to maintain benefits. 1
  • Treatment typically involves weekly sessions initially, with gradual spacing as parents master techniques. 1
  • Effects persist at follow-up evaluations when families continue to apply learned strategies. 1
