## CONTEXT & OBJECTIVES

* To detect frailty in autonomous elderly people at an early stage, using a technological device consisting of various sensors and a tablet that recovers all collected data.

* To evaluate the *a priori* acceptability (M0), then the acceptance (M1) of the multimodal device.

* To observe the influence of the participants' primary motivation on their intention to use the device before and after testing it.

## METHODOLOGY

* 34 volunteers (20 robust, 14 pre-frail according to Fried (2001) criteria): Mean age = 84.6; min = 80; max = 93

* A priori acceptability (M0 - N = 34) and acceptance (M1 - N = 28) measured from Bel (2016)'s acceptability model

* The primary motivation (health vs. science) collected during semi-structured interviews

## RESULTS

### Effect of primary motivation type (health vs. science) on Bel's acceptability model scores

<figure><img src="image_10.png" /></figure>

* No score on the acceptability measure (M0) is affected by the type of primary motivation

* Significant influence of the type of primary motivation on acceptance (M1) in general

* High intention to use the device at M0 and M1, but participants who were committed to their health had a lower intention to use, after one month, than those who were committed to contribute to scientific research

Influence of octogenarians' motivation to participate in a study involving the wearing of an activity tracker. Identification of a potential cognitive bias of our participants, implying a risk of overestimating the validation of our hypotheses
