Abstract
The purpose of this qualitative multiple‑case study is to explore how linking quick‑response (QR) codes (IV) to parent‑focused digital resources shapes caregivers’ experiences and perceived competence (DV) in implementing compassionate applied behavior analytic (ABA) procedures for children with autism spectrum disorder (ASD) in various settings. Anchored in a constructivist paradigm and pragmatic theory, the study aimed to understand how immediate, technology‑based instructional supports aided skill acquisition and independent engagement during parent training. The central research question aims to understand how parents and caregivers construct meaning around the use of a streamlined platform while learning and applying ABA strategies, perceived accessibility, barriers, and effectiveness. 7 parents of diverse backgrounds were selected for the study. Data was gathered through participant self-reflection, reflective notes from open ended interviews, thematic analysis, usage analytics logs, and focus group discussion notes taken throughout the study. The thematic analysis was employed to identify emerging patterns, with peer debriefing, member checking, and audit trails enhancing the trustworthiness of the findings. Caregivers reported high utility, accessibility, and cultural fit. QR codes centralized guidance, replacing fragmented searching and enabling just-in-time rehearsal; brief videos and checklists supported consistent implementation. Analytics indicated purposeful, repeated engagement. PSOC scores improved or remained stable for most participants (largest +22; others +5 and +4; one −2), with two declines reflecting contextual barriers rather than access issues. Findings suggest feasibility, ecological fit, and promise for strengthening caregiver competence across everyday settings.
