Definition & calculation
Numerator: Number of MHPSS clients whose validated distress/functioning score improved by at least the pre-defined clinically meaningful threshold between baseline and follow-up assessment
Denominator: Total number of MHPSS clients with both a baseline and a follow-up assessment in the period
Compare each client's baseline and follow-up scores on a validated, context-adapted instrument and count those crossing the defined improvement threshold.
Formula: (Numerator ÷ Denominator) × 100
Means of verification
Validated, context-adapted pre/post assessment tools (distress or functioning scales) recorded in case files
Interpretation
Typical reporting frequency: Baseline, midline and endline (or annual)
Guidance & common pitfalls
Use context-validated tools and a defined minimum change threshold. Loss to follow-up biases results, so always report the proportion of clients who had paired (baseline and follow-up) assessments.
