What is the validity and reliability of the PHA (Personal Health Assessment) instrument?
ActivHealth reviewed over 40 documents in the establishment of their original Health Risk Appraisal. Later it was tested and further analyzed against another widely accepted HRA from within the industry. This independent study produced statistically similar results. The current online version builds on the original HRA, but has been reworked to focus on modifiable issues within individual lifestyles and related risk factors rather than serving as a predictor for certain disease risks. The responses to the PHA trigger lesson assignment via a series of algorithms and a Personal Wellness Program is established for each individual (“user”). An optional component of the program incorporates blood values to an improved Framingham (+) risk assessment for Heart Disease, Diabetes and Stroke. Note: Our PHD Network program works whether blood values are entered or not, allowing you to reach the people that may not participate in the PHA if you require a blood sample.
