It has been widely recognized that access to mental health treatment is imperative to address current and long-term stressors for children and parents during COVID-19. Internet-delivered Parent-Child Interaction Therapy (iPCIT, previously referred to as I-PCIT) is a strong model for remote service delivery during social distancing restrictions due to its empirical base. However, this treatment modality was not widely implemented before COVID-19, likely due to barriers to providing telehealth services. This mixed methods study conducted a follow-up survey to gather therapist experiences ( = 223) in delivering iPCIT during COVID-19, including qualitative data on the benefits and challenges to delivering iPCIT. The vast majority of therapists (82%) indicated that they transitioned to deliver PCIT via telehealth in response to COVID-19. PCIT caseloads decreased slightly from the first survey to the COVID-19 follow-up survey, but the racial and ethnic composition of caseloads were not significantly different between the two surveys. Of the 183 therapists who transitioned to deliver PCIT via telehealth, 82% expressed interest in continuing to provide iPCIT following the COVID-19 pandemic. Reported benefits of iPCIT included decreased barriers to access and the ability to practice skills within the naturalistic home environment. Challenges to iPCIT were primarily issues with technology as well as other logistical barriers, which could limit engagement for some families. Findings from this study may be beneficial in improving future implementation of iPCIT during and post-COVID-19.
