How to Distinguish Immediacy From Overall Level Change
Separate boundary-window change from the full-phase level comparison, keep matching windows and raw data, and explain why the features can disagree.

How to Interpret a Delayed Effect After a Single-Case Phase Change
Define latency after a single-case phase change, inspect implementation and plausible response dynamics, preserve intervening points, and limit inference.
Clinician guide
How to Evaluate Consistency Across Single-Case Replications
Compare direction, magnitude, immediacy, trend, variability, overlap, context, and implementation without averaging away a weak replication.
Clinician guide
How to Count Demonstrations of Effect in a Single-Case Design
Map each planned phase comparison or tier replication and avoid counting points, participants, or summaries as demonstrations of a single-case effect.
Clinician guide
How to Identify a Basic Effect in Adjacent Single-Case Phases
Compare adjacent single-case phases across level, trend, variability, immediacy, overlap, measurement quality, timing, and alternative explanations.
Clinician guide
How to Use Masked Visual Review for a Baseline Decision
Define reviewer-visible information, collect independent readiness judgments, preserve disagreement and unmasking, and state what masking can address.
Clinician guide
How to Reduce Regression-to-the-Mean Risk in a Single-Case Phase Change
Avoid changing phase solely after an extreme point, preserve the series and rule, and interpret post-change movement with ordinary fluctuation in view.
Clinician guide
How to Review Floor and Ceiling Effects in a Single-Case Baseline
Detect scale-bound compression, review opportunity and task difficulty, and decide whether apparent stability reflects behavior or a measurement limit.
Clinician guide
How to Document a Response-Guided Single-Case Phase Change
Preserve the graph, decision rule, reviewer, timestamp, clinical and access gates, rationale, implementation, deviations, and analysis limits.
Clinician guide
How Fixed, Response-Guided, and Randomized Phase Lengths Differ
Compare three single-case phase-length mechanisms, their required records, flexibility, inference consequences, and humane welfare exception paths.
Clinician guide
What to Do When a Single-Case Baseline Never Stabilizes
Investigate measurement, opportunity, context, and genuine variability, then choose whether to wait, redesign, proceed, or stop with clear limits.
Clinician guide
How to Set a Prospective Phase-Change Rule in a Single-Case Design
Write a phase-change rule with minimum observations, design evidence, clinical readiness, access, ownership, exceptions, and a dated release record.
