Abstract. Persuasive systems that combine numerous behavior change tech-
niques such as self-monitoring and social comparison, expose users to multiple
influences. These influences can in turn generate motivation and/or stress. In a
previous study with users of three commercial applications from the area of
sports, we found that users generated a series of strategies to manage these mul-
tiple influences in order to control their negative effects. Moreover, the man-
agement took place in different times and contexts, as the techniques were de-
signed to be used separately: self-monitoring during exercising, and social
comparison before or after the activity. This paper presents a study in progress
where we explore how the management of multiple influences takes place under
a new condition: when users are exposed at the same time and context to the
multiple influences from self-monitoring and social comparison. We will design
a prototype that delivers the influences from these two techniques under a sin-
gle platform and evaluate it in a laboratory test.
Keywords: Persuasive technology, Multiple Persuasive Techniques, Self-

1 Introduction
Combining multiple behavior change techniques in persuasive systems has become a
regular practice in research prototypes [1] and in commercial applications [2,3]. Be-
havior change techniques are adoptions of techniques, theories, and/or frameworks
from fields such as psychology, which are adapted into computing systems in order to
influence people through technology [4,9]. Such is the case of self-monitoring and
social comparison, techniques from social psychology [6] that have been notably used
in persuasive systems. For instance, in the area of physical activity, systems have
been designed to support athletes to maintain the motivation during training [7], and
to motivate sedentary people to exercise more [8]. A concrete example is Houston [9],
a system that motivates people to be physically active through the use of a pedometer
(self-monitoring), and a mobile social application where the users share, compare and
contrast their performances (social comparison).

Combining various behavior change techniques has been shown as a way to in-
crease the influence over the user, and consequently enhance the possibilities of beha-
vior change [4,2]. However, combining multiple behavior change techniques also
exposes the users to multiple influences. A self-monitoring system can be designed to
deliver three different influences [4,9]. In the same way social comparison can deliver
an additional three influences through social applications [7,10]. Therefore, combin-
ing these two techniques could expose the user to two to six different influences.
The problem of exposing users to multiple influences is related to the generation of
motivation and/or stress, whereby stress could affect people’s performance [11,12].
Literature from social psychology demonstrates that people generate personal strate-
gies to manage multiple influences in order to control the effects that they generate
over their behaviors and thoughts [13,14]. Moreover, some strategies catalyze the
negative effects of pressure in to motivators [12].
Persuasive technologies are systems explicitly designed to motivate people to
achieve specific behavior changes [4]. Currently, there is a lack of understanding of
the way people manage multiple influences, and the way the users deal with the stress
or pressure generated by these influences. Therefore, the present research is interested
in understanding the use of personal strategies to manage the multiple influences gen-
erated by persuasive technologies.
2 Background
In the study one of the present research, we explored the ways in which 16 users
managed the multiple influences generated by three commercial applications from the
context of sports, which combined self-monitoring and social comparison. Two im-
mediate factors emerged from the data analysis. First, the strategies to manage the
influences were arranged in two major groups: for self-monitoring and for social
comparison. Second, these strategies were used in different times and contexts. A
possible explanation for these conditions is the design of the applications. Even self-
monitoring and social comparison formed part of one unique overall persuasive sys-
tem; each technique was supported by independent systems, delivering their influ-
ences in separate moments, generating a management of multiple influences in differ-
ent times and contexts.
3 Problem
The management of multiple influences in persuasive systems is a new and unex-
plored topic that provides opportunities and challenges for the design of persuasive
systems. Presently, we have a basic understanding of the management of multiple
influences through our previous study. However, it remains unknown as to how the
management of multiple influences could take place, when a single platform and in-
terface delivers the multiple influences of both techniques (self-monitoring and social
comparison) at the same time and context.

4 Research Design
Currently, there is no technology available to understand the management of multiple
influences simultaneously. Therefore, we will design a prototype that will work as a
research tool within the context of exercise.
Design of the prototype.
The design of the prototype has two main stages: the generation of the prototype
and an evaluation of its persuasive design. To generate the prototype two design
workshops will be conducted based on a collaborative design process between Hu-
man-computer interaction experts and regular performers of physical activity. We
expect that this paring will enrich the design of the prototype [15]. The product will
be paper prototypes that will depict the shapes and contents in which self-monitoring
and social comparison should deliver their influences to the user during exercising.
The activities in the workshop are: presentation of current systems that combine
these two behavior change techniques. Secondly, a scenario will be explained to ex-
plain the conditions of use of the prototype. Thirdly, a brainstorming session will start
to trigger design ideas. Finally, the design of paper prototypes will take place, con-
cluding with their presentation to the group.
To enrich the persuasive design of the prototypes, the digital versions will be pre-
sented to an expert panel formed by two personal trainers and two psychologists spe-
cialized in behavior change in the area of sports and weight management. Discussion
about the prototype will be encouraged in order to get feedback regarding the pros
and cons of the persuasive system. The seminars and panel will be recorded allowing
the researchers to observe the process and find potential elements that sketches could
not depict. Based on the findings, low fidelity prototypes will be generated.
Evaluation of the prototype.
The low fidelity prototype product will be evaluated with 10 participants that exer-
cise frequently, who have to be over 18 years old. The laboratory evaluation will take
place at Interaction Design Usability Lab (IDL) of The University of Melbourne,
where the participants will be sitting on a chair at a table. A scenario of use will be
given to the participant, who will be invited to describe the employment of the proto-
type. During and after the use of the prototype, participants will be asked about their
feelings and thoughts related to the exposure to multiple influences. The evaluation
will be recorded and notes will be taken by the researcher. The data collected will be
transcribed and coded using a 3 step coding process [16].
5 Outcomes
We are interested to find out if the strategies from study number one are similar or
different to the strategies from study number two. Possible differences or similarities
will help us to increase our current understanding of the management of multiple
influences from persuasive technologies. Moreover, it is expected that the present
22 First International Workshop on Behavior Change Support Systems (BCSS 2013)
research could give insights to Human-computer interaction designers and researchers
about the implications of combining various behavior change techniques in persuasive
systems. In particular when this leads to exposing the user to multiple influences,
which in turn could generate not just motivation but also stress.
