Study summary

The aim of the current proposal is to determine if the PCIT treatment manual can be successfully utilized for preschoolers with ASD and disruptive behavior (across a range of intellectual functioning levels) and to evaluate its ability to significantly decrease measures of problem behavior. It is hypothesized that the current manual will require few modifications for use with ASD and that, in comparison to a wait-list control group, families who undergo PCIT training will evidence significant gains on measures of parenting stress, child externalizing behaviors and compliance to parental requests. To address the pilot study aims, we will recruit a total of 25 families of children with ASD (ages 2.6-6.11 years) whose children are already receiving intensive, one-on-one behavioral treatment services (15-30 hours per week) but no structured parent training. Families will be randomized to either intensive services + PCIT or intensive services alone (wait list control). Assessments will be completed at baseline, mid-treatment (9 weeks post baseline), post-treatment (18 weeks after the baseline assessment) and long-term follow-up (12 weeks post-treatment). PCIT families will attend 16 weekly, one-hour coaching sessions. Both active treatment and wait-list control families will continue to receive intensive ABA services in the home or community. Control families will receive PCIT training after 18 weeks on the "wait-list." The aims of the pilot study are:

  1. To assess the utility of the current PCIT treatment manual with preschoolers with ASD and disruptive behavior and their parents;

    Hypothesis 1: The current PCIT treatment manual will be able to be utilized with families of children with ASD with only minimal modifications.

    Hypothesis 2: Families of children with ASD will consistently attend PCIT sessions.

  2. To determine if PCIT with this population will result in an increase in appropriate parent behaviors and a subsequent decrease in targeted child behaviors (e.g., direct assessment of noncompliance, behavior rating scales).

Hypothesis 3: Families receiving PCIT training will evidence statistically greater decreases on measures of disruptive behavior, quality of parent-child interactions and parental stress than families on the wait-list control group.

Read the detailed description

Young children with ASD often present with a range of externalizing behavior problems, including aggression, tantrums and difficulty transitioning. Interventions based on the principles of applied behavior analysis (ABA) have been shown to offer an effective means of addressing many of these concerns. Parent-Child Interaction Therapy (PCIT) is a manualized, empirically supported parent coaching intervention that has been found to be highly effective for typically developing preschoolers presenting with a range of mental health concerns. It also holds considerable promise as a potentially effective treatment for children with ASD. The focus of PCIT treatment is to both improve parent-child interactions and to reduce child behavior problems. PCIT involves the coaching of parents in real-time, via a one-way mirror and a "bug-in-the ear" device that allows the therapist to provide feedback and directions to the parent while interacting with his/her child. The aim of the current proposal is to determine if the PCIT treatment manual can be successfully utilized for preschoolers with ASD and to evaluate its ability to significantly decrease measures of problem behavior. It is hypothesized that the current manual will require few modifications for use with ASD and that, in comparison to a wait-list control group, families who undergo PCIT training will evidence significant gains on measures of parenting stress, child externalizing behaviors and compliance to parental requests. To address the pilot study aims, we will recruit a total of 25 families of children with ASD (ages 2.6-6 years) whose children are already receiving intensive, one-on-one behavioral treatment services (15-30 hours per week). Families will be randomized to either intensive services + PCIT or intensive services alone (wait list control). Assessments will be completed at baseline, mid-treatment (9 weeks post baseline) and post-treatment (18 weeks after the baseline assessment). PCIT families will attend 20 weekly, one-hour coaching sessions. Both active treatment and wait-list control families will continue to receive intensive ABA services in the home or community. The results of this study will provide pilot data in a subsequent application for federal funding to conduct larger controlled trials, including examining the use of PCIT in school-age children with ASD and intellectual disability and to assess the individual and combined efficacy of PCIT and psychopharmacological treatment.

Interventions

  • BehavioralParent Child Interaction Therapy

    Parent-Child Interaction Therapy (PCIT) is a research-supported parent coaching intervention that has been found to be highly effective among typically developing preschoolers presenting with a range of mental health concerns, especially defiance and noncompliance.6 PCIT holds considerable promise as a potentially effective treatment for children with ASD because it directly addresses the behaviors parents of children with ASD report to be most problematic for them - defiance, stubbornness, and temper tantrums. PCIT is theoretically consistent with other approaches that have shown promise in treating ASD (i.e., behaviorally-based); however, PCIT is unique in that it incorporates a socially-based initial phase which may have some unique benefits for children with ASD.

Primary outcomes

  1. Eyberg Child Behavior Inventory

    Eyberg Child Behavior Inventory (ECBI). For families receiving PCIT training, the ECBI will be completed at screen, at each PCIT training visit and at the 12-week post-treatment visit. Wait-list control families will complete the ECBI at screen as well as at weeks 9 and 18. Reported week 9. The ECBI contains the Intensity Score calculated from 36 items rated on frequency of behavior from 1 (Never) to 7 (Always). Intensity score range is 36-252, with higher scores indicating a higher frequency of problem behaviors. The ECBI contains the Problem Score calculated from 36 items rated on whether the particular behavior is considered by the to be a problem (yes) or not (no). Problem score range is 0-36, with higher scores indicating a higher frequency of problem behaviors.

Secondary outcomes

  1. Parental Stress Index-4 Short Form

    Parental Stress Index-4 Short Form (PSI) is comprised of several subscales that are independently measured and also combined to create a total score. Scores are calculated from 36 questions that rated as Strongly Agree/Agree/Not Sure/Disagree/Strongly Disagree by the parents. Ratings are attached to a 5-point Likert scale. PSI Defensive Responding subscale range: 7-35. Lower scores indicate higher defensive responding from parents. For the PSI Parental Distress subscale, range 12-60. Higher scores indicate higher parental stress in the parenting. For the PSI Parent-Child Dysfunctional Interaction subscale, range 12-60. Higher scores indicate parents feel their child is not meeting their expectations when interacting. For the PSI Difficult Child subscale, range 12-60. Higher scores indicates parents view their child to be difficult to parent. For PSI Total Stress, range 43-215. Higher scores indicate higher stress.

Collected over The time frame that information on adverse events was collected depended on which treatment assignment was made. For individuals who were assigned to immediate PCIT training, adverse event data was collected over a period of 18 - 30 weeks, dependent on the subject's ability to schedule training. For individuals on the wait list for PCIT, adverse event data was collected over a period of 30 - 48 weeks, dependent on the subject's ability to schedule training.. Non-serious events are listed at a 0% frequency threshold.
