Assessing acceptance and commitment therapy for adolescent mental health: Single-case A-B design with high temporal density assessments

“…Given the present sample and use of a group-based ACT intervention, a more robust single-case experimental design (e.g., a randomized multiple-baseline design) was not possible. As such, a limitation of the present study is that we cannot rule out alternative explanations (e.g., maturation) for changes in participants' ratings over time (Belisle et al, 2021;McDonald et al, 2017). Future research should employ a multi-arm concurrent multiple baseline design to minimize potential confounds.…”

“…The present study employed a single-case A-B design (Phase A = baseline/preintervention; Phase B = post-intervention and follow-up period). The A-B design is generally considered to be the most basic type of single-case design (Belisle et al, 2021). The A-B design may also be referred to as a "phase change without reversal/withdrawal", "quasiexperimental pre-post design", or a type of "interventional n-of-1" (McDonald et al, 2017;Tate et al, 2016).…”
