Parent-Led Cognitive-Behavioral Teletherapy for Anxiety in Youth With ASD

Study Overview
=================
Brief Summary
-----------------
This study implements an anxiety-focused, parent-led, therapist-assisted cognitive behavioral teletherapy for parents of youth with ASD and anxiety.

Detailed Description
-----------------
Anxiety disorders affect 50-80% of children with autism spectrum disorder (ASD) and are associated with significant life impairment and worsening trajectory without treatment. The most effective psychotherapy for anxiety in youth with and without ASD is cognitive behavioral therapy (CBT), but many families are not able to access CBT due to the cost, practicalities of attending treatment sessions, and limited availability of trained therapists. Alternative models of service delivery are greatly needed, with particular promise of parent-led therapist-assisted (PLTA) models and telehealth delivery formats. Parents may benefit from additional information regarding how to optimize the delivery of CBT for youths with ASD given the potential impact of ASD symptomology on core CBT skills. Thus, this project aims to improve access to anxiety-focused Parent-Led Therapist-Assisted CBT for parents of youth with ASD. Parent-led low-intensity treatment models can improve accessibility, efficiency, and mental health treatment cost. Lower intensity treatment models provide a treatment option that is less costly and burdensome for parents; it is understood that some individuals will respond to the first step and others will require additional treatment to achieve anxiety reduction. However, understanding how many families, and which families, can benefit from a lower intensity model has dramatic benefits for improving access, allocating more intensive services for those most in need, and reducing barriers (e.g., distance). Thus, this study will examine the effectiveness of two anxiety-focused PTLA CBT telehealth models: 1) low-intensity therapist assistance (LTA) and 2) standard therapist assistance (STA). Overall, this study will provide important information regarding the potential benefits of two different approaches to parent-led interventions for youth with ASD and anxiety when delivered via telehealth.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Low-Intensity Therapist Assistance (LTA)<br>Parents will receive four 30-minute supportive video calls with a therapist over the 12 weeks of treatment. | Behavioral: Cognitive Behavioral Teletherapy LTA<br>* Participating families will receive a copy of the book 'Helping Your Anxious Child, 2nd Edition', as well as the companion parent and child workbooks, to use at home and in session with the therapist. During each of the four videoconferencing sessions, therapists will serve to provide encouragement and support as the parent works through the program independently.<br>|
| Active Comparator: Standard Therapist Assistance (STA)<br>Parents will receive ten 60-minute supportive video calls with a therapist over the 12 weeks of treatment. | Behavioral: Cognitive Behavioral Teletherapy STA<br>* Participating families will also receive a copy of the book 'Helping Your Anxious Child, 2nd Edition', as well as the companion parent and child workbooks, to use at home and in session with the therapist. During each of the ten videoconferencing sessions, therapists will guide the parent through the implementation of the program, including explaining materials, assisting to develop planned therapy activities with the child, and problem-solving as needed.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 6-item Pediatric Anxiety Rating Scale | Clinician rated child anxiety severity throughout the past week. Each item is scored on a 0 to 5 scale (higher scores correspond to greater severity), yielding a total between 0 and 30. | 7 days | 
| Clinical Global Impression-Improvement | Clinician rated child psychopathology improvement since initial rating. A single item is scored 0-6 (0 = very much worse; 6= very much improved). | 7 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical Global Impression-Severity | Clinician rated child psychopathology severity rating. A single item is scored 0-6 (0= no illness; 6= extremely severe symptoms). | 7 days |
