Immediacy across repeated phase changes should be summarized at each transition before any overall statement. Predefine how many observations at the end of one phase and start of the next form the edge window. Compare their level, direction, overlap, and latency. Preserve raw values and report consistency or exceptions across transitions rather than averaging away failed demonstrations.

Define the edge window

Choose a fixed number of adjacent valid observations or another stated rule before comparing transitions.

Calculate each transition

Report the end-phase and start-phase summaries, their signed difference, overlap, and elapsed time.

Preserve failed or delayed changes

A transition without the expected immediate pattern remains in the review. Note latency and contextual changes.

Integrate replications

Assess whether direction and magnitude are reasonably consistent across opportunities for demonstration. Do not treat one strong edge as proof of the full design.

Lock the transition table before summarizing

List every planned phase change in chronological order. For each transition, preserve the last valid observations from the ending phase and the first valid observations from the starting phase under the predeclared edge-window rule. Include timestamps, gaps between phases, missing-state decisions, context changes, and the person's report.

Use the same summary method at every edge unless a documented design reason requires a different analysis. A three-point median should remain a three-point median across transitions. If one edge has fewer valid points, show it as incomplete or run a clearly labeled sensitivity analysis instead of changing the window silently.

Keep direction and magnitude visible

Define the signed change so the reader knows what a negative or positive value means. When lower values are preferred, subtract the ending-phase median from the starting-phase median and label a negative result as movement in the preferred direction. Report the absolute size as well when that is easier for the client and team to understand.

The overall statement should retain the sequence of effects. Counts such as three of three transitions in the preferred direction can summarize consistency, while the separate changes show whether the pattern weakened, strengthened, or was delayed. Do not average the edge changes if the average would hide a reversal or a failed replication.

Apply one edge-window rule to repeated phase changes

The phase-edge immediacy table for Quincy identifies the phase labels, improvement direction, raw observations, missing-state rule, reference value or line, formula, tie rule, calculation owner, and review date before a supplemental result is interpreted.

Work the single-case example for Quincy

Quincy's three A-to-B transitions use three-point medians. Replication 1 changes from 8 to 4, a decrease of 4; replication 2 changes from 10 to 8, a decrease of 2; replication 3 changes from 7 to 6, a decrease of 1. All move in the intended direction, while the immediate difference becomes smaller.

The transition-level consistency count is therefore 3 of 3 in the preferred direction. The median magnitude of the three decreases is 2, but that single value cannot replace the sequence of -4, -2, and -1. The shrinking difference could reflect weaker experimental control, baseline differences, learning history, context, or ordinary variability and needs review on the full graph.

Audit reproducibility for Quincy

Quincy's table retains the six edge values at each transition, phase dates, direction, and any gap between phases. It reports differences of minus 4, minus 2, and minus 1 separately.

Review latency, overlap, and context

An immediate level change is only one visual-analysis feature. Note whether the first point changes promptly, whether edge windows overlap, whether trend changes, and whether the pattern persists. A delayed improvement can still matter clinically, but it should not be labeled immediate.

Record changes in setting, people, schedule, measurement, access, health, or implementation around every edge. If an interruption creates a long gap, show the elapsed time and assess whether adjacent-point language remains meaningful. Keep any transition affected by an unresolved data-quality problem in the table as held.

Protect client relevance for Quincy

During Quincy's repeated adjacent phase comparisons review, keep AAC, interpreters, mobility, food, water, bathroom use, prescribed care, health support, rest, relationships, and emergency help available. Use accessible communication to ask whether the measured outcome and magnitude matter to the person. A favorable statistic cannot repair an unwanted goal or inaccessible plan.

Use current single-case evidence for Quincy

For Quincy's calculation, the BCBA Test Content Outline supplies examination scope for graphing, interpretation, experimental design, and data-based evaluation. The BACB ethics hub and CASP summary provide professional context. The WWC Version 5.0 handbook is an education-research evidence standard, not a clinical authorization rule. A single-case methods review documents PND, NAP, and extended-line formulas. Research on structured visual-analysis aids and decision accuracy across overlap measures supports using calculations as transparent supplements while retaining metric and design limits. ASHA supports continuous AAC access.

Close Quincy's analysis review

Review the phase-edge immediacy table with Quincy and the responsible clinician. Preserve raw data, graph, phase definitions, calculation version, coverage, ties, limitations, client input, decision, owner, and next review date. Reopen the analysis when data, context, access, health, goal, phase, or method changes.

Clinician review checklist

  • Are all planned phase transitions listed, including weak, delayed, and reversed patterns?
  • Is one predeclared edge-window and summary rule applied consistently?
  • Can another reviewer reproduce each ending-phase and starting-phase summary from raw points?
  • Are signed direction, absolute magnitude, overlap, latency, and between-phase gaps visible?
  • Does the summary preserve the -4, -2, and -1 sequence instead of hiding it in one average?
  • Are incomplete edges and context changes retained with owners and resolution states?
  • Is immediacy interpreted with the full graph, design logic, implementation, and Quincy's priorities?
