Why 5 Minutes with PREP Produces Better Data
PREP’s 5-minute format isn’t a shortcut. It’s a design principle validated over 40 years of research. Longer assessments don’t produce better data—they produce noisier data.
Complexity introduces error. Narrative-based or multi-part questions increase the likelihood of confusion or misinterpretation. When test-takers aren’t sure what a question means, their responses measure comprehension as much as personality. PREP’s straightforward 8th-grade vocabulary eliminates that noise.
Research confirms it: as assessments lengthen and become more complex, response quality degrades. Neutral or “I don’t know” responses rise. Strong responses—the meaningful ones—fall. Each additional hour of survey time increases question-skipping by. After 15 or 20 minutes, test-takers start overthinking, revisiting earlier answers, adjusting based on how they want to appear rather than how they actually are. First-impression responses—captured in PREP’s brief format—are more authentic and more predictive.
Binary choices force false answers. Many assessments rely on forced-choice formats: “Are you more A or B?” But people aren’t that simple. Research shows that respondents score across a spectrum on the personality scales—not at the extremes these formats assume. When neither option fits, test-takers pick arbitrarily, and the data reflects that. Psychometric research identifies forced-choice formats as producing “ipsative” data with “problematic psychometric properties.” PREP’s design avoids this trap.
Implementation matters. A 30-minute assessment sounds thorough, but consider the reality: you’re asking employees to add stress to their day in order to measure stress. You’re reducing productivity in order to improve it. Survey fatigue leads to careless and suboptimal responses, and leading to decreased survey accuracy.” Compliance drops. Resentment builds. Results suffer. PREP respects people’s time—and gets better data because of it.
The result: higher completion rates, more accurate profiles, and insights people actually trust.
