Primary Outcome Measures:
  • Feasibility of a novel behavioral treatment [ Time Frame: 24 months ] [ Designated as safety issue: No ]

    Assessment of Outcome:

    Attendance. Attendance to parent education sessions will be recorded by the therapist.

    Parent utilization. To assess the acceptability of the PRT approach, parents will be asked to keep a weekly log of procedure use, including overall estimated duration and choice of activities.

  • Acceptability of a novel behavioral treatment [ Time Frame: 24 months ] [ Designated as safety issue: No ]

    Assessment of Outcome:

    Parent satisfaction. At post-treatment, parents will be asked to complete a Likert-scale and short response questionnaire rating their satisfaction with various aspects of the program
