Evidence-based health and well-being for entire populations.

Our Services

Clinician Empowerment. Administrative Oversight.

Our Clinical Dashboard puts stage-matched guidance in the hands of clinicians and coaches. It enables them to quickly access a patient’s health risks, give patients brief evidence-based behavior change advice, and track their behavior change progress. The dashboard also offers “stage-on-demand”. Whether or not a patient has completed Pro-Change’s HRI, a clinician can simply click on a behavior to surface Pro-Change’s validated stage of change assessment for that behavior, allowing the clinician to quickly and accurately assess stage of change.

Aggregrate Reporting

Aggregate reporting in an Administrative Portal rounds out the Suite, affording administrators rich data to use in making decisions and addressing population health risks and goals. Program usage and behavior progress reports are available.

Sample aggregate reports

Coaching/Counselor Version

A coaching version of each program is fully integrated with the participant version. However, the coaching version is presented as bulleted lists that guide the feedback to ensure treatment fidelity, while allowing for the coach’s clinical judgement and their own way of working with patients.

Behavior Change Program Outcomes

Pro-Change’s evidence-based program outcomes are from randomized clinical trials, predominantly funded by the National Institutes of Health. The outcomes measure behavior change from baseline to follow-up among participants who were not engaging in the healthy behavior at baseline.

The trials were performed with scientific rigor with results published in peer-reviewed journals such as the American Journal of Health Promotion, Preventive Medicine, Health Psychology, American Journal of Public Health, and Disease Management.

For all outcomes reported, the intervention group statistically outperformed the control group.
