The goal of this clinical trial is to evaluate the feasibility, usability, and preliminary benefits of implementing ACT Together for parents of children with disabilities in pediatric outpatient clinics. ACT Together includes six self-paced, web-based modules and brief weekly one-on-one coaching sessions led by a trained occupational therapist. The program is based on acceptance and commitment therapy (ACT), which teaches practical skills to help people handle stress and difficult thoughts or feelings while taking steps toward what matters to them.

The main questions this study aims to answer are:

• Can parents and occupational therapists complete the study activities as planned (e.g., module completion, coaching sessions, and surveys)?
• Is the program usable and acceptable/appropriate/feasible to implement in this setting?
• Do parents show improvements in mental health and coping-related outcomes after participating in the program?
• What are the experiences and perspectives of parents and therapists regarding the program?

Parents as participants will:

• Complete six self-paced web-based modules and brief weekly individual phone coaching sessions with a trained occupational therapist working in pediatric outpatient clinics.
• Complete online questionnaires before starting and after completing the program.
• Take part in one online interview about their experiences and perspectives on the program.

Occupational therapists as participants will:

• Complete therapist training materials and deliver brief individual phone coaching sessions to parent participants, including completing a post-session checklist.
• Complete brief online questionnaires before starting and after delivering the program.
• Take part in one online interview about their experiences and perspectives on the program.

Parents of children with disabilities often experience elevated psychological distress and may face barriers to accessing timely, evidence-based support. ACT Together is a research-developed program designed to support parents' coping and psychological well-being in a scalable format that can be implemented in pediatric outpatient clinic settings. This study will be a one-group, pretest-posttest mixed-methods pilot to evaluate the feasibility and implementation of ACT Together when delivered as (1) six self-paced, web-based acceptance and commitment therapy (ACT) modules and (2) six brief phone coaching provided by occupational therapists working in pediatric outpatient clinics. All study activities will be coordinated by the University of South Florida (USF) and will be completed remotely using secure online platforms; coaching sessions will be delivered by phone.

Occupational therapists will be recruited via a study flyer and will complete an online screening process. Eligible therapists will complete electronic informed consent and baseline questionnaires and will then access therapist-specific training materials in Canvas. Parents of children with disabilities will be recruited through clinic-based flyer dissemination (e.g., posting or placing flyers at reception). Interested parents will contact the study team and will complete online screening. Eligible parents will complete electronic informed consent and baseline questionnaires and will then receive access to the parent Canvas course.

ACT Together will include six self-paced, weekly web-based ACT modules and six brief coaching sessions (approximately 15-20 minutes each) delivered after each module by a trained occupational therapist. The modules will be hosted on the USF Canvas platform. Two separate Canvas courses will be used: a parent course that includes ACT modules and activities for parents, and a therapist course that includes training materials and structured coaching guidance to support delivery of the brief coaching sessions. Coaching sessions will use structured questions and guidance developed for research purposes and are not intended as standard clinical care. Coaching sessions will be conducted by phone at a mutually agreed time between the parent and the participating occupational therapist. Occupational therapists will complete a brief session checklist in Qualtrics after each coaching session to document that required components were delivered; these checklists will be used to calculate session-level coaching fidelity.

Parents will be encouraged to complete approximately one module per week and to participate in a coaching session after each module over approximately 7-8 weeks. Both parents and occupational therapists will complete questionnaires at pretest and posttest. Parent-reported outcomes will include depressive symptoms, anxiety, perceived stress, psychological quality of life, and ACT-related processes (psychological inflexibility, cognitive fusion, and values-based engagement). Posttest implementation measures will capture perceived usability, acceptability, appropriateness, and feasibility (reported separately by parents and therapists).

Both groups will complete a one-time individual interview at posttest to understand user experiences and implementation perspectives and to inform refinement of the program and study procedures. Post-program interviews will be conducted via the HIPAA-compliant version of Microsoft Teams and will be audio recorded. Interviews are expected to last approximately 40 minutes.

The Canvas course will capture program engagement metrics (e.g., logins, time spent, and module completion) and responses to in-program activities for research purposes. Occupational therapist checklists completed after each coaching session will provide implementation documentation and fidelity indicators. Feasibility indicators will include enrollment rate, retention, and adherence (completion of modules and coaching sessions).

All data will be collected electronically using university-approved secure platforms (Qualtrics, the ACT Together program hosted on USF Canvas, and HIPAA-compliant Microsoft Teams). ACT Together will not be publicly available and will be accessible only to enrolled participants using study-specific login credentials. Identifying information will be collected only as needed for study operations (e.g., communication and compensation) and will be stored separately from research data. Study data will be stored in secure, access-controlled USF systems (including USF Box), with access restricted to authorized study personnel. Only de-identified, aggregate results will be used for dissemination.
