NCT06984809

Brief Summary

The goal of this clinical trial is to test if the invest in Play (iiP) parent program can reduce problem behaviors in children and improve parenting practices in families with children who show challenging behaviors. The main questions it aims to answer is: • Does the iiP program reduce children's problem behaviors? Researchers will compare families in the iiP program to families in a control group to see if the program leads to better outcomes for children and parents. Participants will be randomly assigned to either the iiP program group or the control group and complete surveys before and after the program to see if iiP is reducing children's problem behaviors.

Outcome Measures

Primary Outcomes (1)

  • Change in the Eyberg Child Behavior Inventory (ECBI) score at different time points (from baseline up to 12 weeks).

    Child problem behavior will be measured using the Eyberg Child Behavior Inventory (ECBI), where the change score from baseline to 12 weeks post intervention is the primary outcome. The measure consists of 36 items, which is scored on parents' notion about the intensity (1 = never to 7 = always), and whether child behavior is a problem (0 = no and 1 = yes, range 0-36). A total score is calculated, ranging from range 36-252. High intensity scores indicate more intense problems, and a high problem score indicate a higher frequency of problem behaviors. The ECBI has demonstrated strong internal consistency, test-retest reliability, and discriminant validity and has been shown to be a sensitive indicator of intervention efficacy for child behavior problems.

    From baseline to the end of treatment at 12 weeks.

Secondary Outcomes (8)

  • Change in the Social Competence Scale-Parent (SCS-P) score at different time points (from baseline up to 12 weeks).

    From baseline to the end of treatment at 12 weeks.

  • Change in the Kidscreen-10 score at different time points (from baseline up to 12 weeks).

    From baseline to the end of treatment at 12 weeks.

  • Change in Strengths and Difficulties Questionnaire (SDQ) score at different time points (from baseline up to 12 weeks).

    From baseline to the end of treatment at 12 weeks.

  • Change in the Parenting and Family Adjustment Scales (PAFAS) score at different time points (from baseline up to 12 weeks).

    From baseline to the end of treatment at 12 weeks.

  • Change in the Parent Stress Scale (PSS) scores at different time points (from baseline up to 12 weeks).

    From baseline to the end of treatment at 12 weeks.

  • +3 more secondary outcomes

Other Outcomes (9)

  • Change in Eyberg Child Behavioral Inventory (ECBI) score from post-intervention to three months follow up.

    From post-treatment to three months post intervention.

  • Change in the Social Competence Scale-Parent (SCS-P) score from post-intervention to three months follow up.

    From post-treatment to three months post intervention.

  • Change in Kidscreen-10 score from post-intervention to three months follow up.

    From post-treatment to three months post intervention.

  • +6 more other outcomes
