Stringent Research Standards

Since the beginning, stringent research standards have been used so all PDP system results are as accurate as they can be.

  • Research was based on statistical analysis, not proving a theory.
  • Survey instruments were researched and developed by credentialed professionals, research experts, behavioral scientists, and experienced leaders in business and industry.
  • Survey instruments were designed to elicit an individual's most natural and unbiased response 
  • While the industry standard for correlating coefficients is only 60%, PDP's standard is a minimum of 80%.
  • A variable norm algorithm accurately determines an individual's strengths in comparison to other strengths rather than to population norms.
  • Initial research sample consisted only of working adults—not students.

These standards ensure a comprehensive, predictable and accurate assessment system to place employees, help team members work together, and empower managers. The result is a top notch solution of helping businesses understand their people and be more successful.

Additional Research Studies & Information

 

Study:
Monograph No. 10

 The ProScan Survey was developed from a sound theoretical base, a carefully selected normative sample, and appropriate statistical procedures. Monograph No. 10 describes work performed on the standardization of the ProScan Survey. Evidence from initial experiments showed high coefficients of reliability and validity.

Study:
Post Normative:

The Post Normative Study was designed to document certain practical effects of the structural integrity of the ProScan Survey. The plan called for analyses of responses to the ProScan Survey obtained on two groups of adults who were thought to differ significantly on one or more behavioral traits. This was a deliberate attempt to stretch the instrument, to determine if the set of terms that predict a given behavioral trait is the same when the group means are at opposite ends of the scale.

Study:
Disparate Impact

A study to assess the potential disparate impact of Professional DynaMetric Programs ProScan behavioral assessment device used for employment selection. Disparate impact occurs when members of one applicant group have a greater opportunity for employment than members of another applicant group.

Real-world Proof

96% of individuals surveyed since 1977 agree in field testing that their ProScan results are accurate.

"Wow...this PDP ProScan Report was a reality check and very much accurate."
 
"I was amazed at how dead on it described me." 
 
"Nailed it!"
 
"Every time I go against what the ProScan says, I'm wrong."
