Methodological Guidance for Single-Case Graph Construction in Counseling Outcome Research and Program Evaluation

Abstract

In this article, we outline standards and recommendations for single-case research design (SCRD) graph construction to improve readability, transparency, and interpretation. Prior research indicates large variability among graph representation resulting in misinterpretation and lack of clarity of reported findings. Prominent graph features are discussed including esthetic and analysis altering characteristics. We provide a conceptual checklist along with visual and narrative descriptions to support the construction of SCRD graphs and help guide practitioners and researchers with reporting and displaying SCRD data.
