As the recognition of health trackers has elevated, so have the alternatives to make use of such gadgets to not solely monitor health objectives but in addition improve the motivation to satisfy these objectives. Researchers within the School of Engineering and the School of Well being and Human Improvement at Penn State have teamed up to make use of management methods engineering instruments to tailor motivational messages despatched to particular person system customers.

The outcomes of their examine had been printed at this time (Oct. 7) in Well being Psychology.

“One of many actually thrilling advances of the final 15 years has been the arrival of wearable and moveable client expertise that can be utilized to assist promote bodily exercise,” stated David Conroy, professor of kinesiology and human growth and household research, and co-principal investigator on the paper. “You may get real-time suggestions from these gadgets and monitor your objectives, and you may even push individuals messages, relying on what their objectives are and what their conduct is. We all know that these messages work nicely for bettering conduct on common. However no one is common, and we do not understand how to verify every particular person constantly will get the best profit from a restricted variety of messages.”

Conroy stated that researchers have tried a number of methods, together with messages which are particular to sure inhabitants segments; messages based mostly on current conduct—for instance, sending considered one of two totally different messages relying on if a person did or didn’t meet their objectives the day past; and customizing the messages by placing in an individual’s title or one thing they could like. Thus far, none of those approaches has confirmed to be constantly efficient in bettering the messages’ results.

The brand new messaging method developed by Conroy and Constantino Lagoa, co-principal investigator and professor {of electrical} engineering, applies instruments used usually in managed methods engineering to conduct science.

“Primarily, we’re utilizing the identical mathematical instruments that individuals in management engineering normally use to mannequin behaviors as differential equations,” Lagoa stated. “We’re utilizing these fashions to design suggestions controllers that have in mind the present state of the individual and along with the mannequin determine what’s the greatest time to ship the messages.”

Conroy emphasised that establishing the right dosing—which means the kind of message and its timing, frequency and context—is a vital half to this method.

“We’re actually prioritizing understanding the dosing in order that we solely ship the proper message on the proper time and in the proper context so individuals get the advantages that they are in search of,” he stated. “We do not wish to disrupt them with out them getting the payoff that they are in search of.”

The researchers discuss with this individualized method as precision behavioral medication.

“This is likely one of the first research that was capable of leverage knowledge collected from every particular person and zoom in on his or her private response,” Lagoa stated.

One of many principal examples of how the researchers personalised the messages was by contemplating the climate within the space of the person, noting that sure messages had been more practical for sure people on wet days, sizzling days and so forth.

The researchers acknowledged the potential concern individuals could have about buying and selling privateness for personalization however stated that the automation implies that the information can be utilized after which discarded, versus saved, and the situation settings solely must be approximate to know the climate and customise the messaging appropriately. Additionally they stated, if their method is commercialized, customers would have the ability to alter their settings to pick how a lot data to share, and so they plan on conducting extra analysis earlier than making use of their method to a bigger inhabitants.

“We have established right here is there is a new instrument to make use of with a longtime drawback,” Conroy stated. “Our subsequent challenge will concentrate on establishing efficacy: Does this work higher than sending messages at random or not sending messages in any respect? However as soon as we set up efficacy, I might think about that it would be very engaging to system producers to think about this type of method.”

Different authors of the paper embody Sarah Hojjatinia, a former electrical engineering graduate pupil and at present at Superior Security & Consumer Expertise; Sahar Hojjatinia, {an electrical} engineering graduate pupil; and Deborah Brunke-Reese, analysis challenge supervisor for the Motivation Lab within the School of Well being and Human Improvement.
