ABSTRACT
Based on the expanding usage of smartphones as
the platform for computer applications, this paper
addresses the information asymmetry between
personal and factual observations that inform a
decision-making process. The purpose of this pa-
per is to propose a model to help self-guided be-
havioral change based on collection of personal
information. A mobile application exemplifies
self-guiding behavioral change through the col-
lection of daily quantitative data and the retrieval
of descriptive statistics during decision-making.
INTRODUCTION
The widespread use of the smartphone introduced
a behavioral change in daily decision making.
Many people use smartphones to store, retrieve,
and search for information. Smartphones com-
municate with a variety of services over the inter-
net, and the applications used create a plethora of
metadata about how people use them (Azar 2003;
van Velsen, 2013). The internet is a medium for
widespread data distribution and collection,
which has been proposed as a medium for behav-
ioral interventions (Ritterband, 2009).
People’s perspectives about the use of mobile ap-
plications to achieve health related behavior
changes is understudied according to Dennison et
al. (Dennison, 2013). Taking advantage of smart-
phones’ growing computational power and mobil-
ity in order to self-guide behavioral changes, re-
quires that the technology allows storage and re-
trieval of data in ways we deem helpful to deci-
sion making.
Kahneman and Tversky developed their prospect
theory to analyze decision making by considering
risks (Kahneman, 1979). The authors posit that
expectations drive people’s perspective in charac-
terizing changes either as gain or as loss. People
have different attitudes, each of which alters
judgement differently. The difference between
what we think is going on and what is actually
going on is information asymmetry. The concept
of information asymmetry is related to transac-
tions between agents that possess different levels
of information.
In the context of decision making, information
asymmetry manifests as a lack of knowledge that
alters the perception of the situation. People often
address a lack of information with information
from past experience if available. In other words,
people link previously experienced prospects to
similar prospects that are under consideration.
Hadar and Fox investigated how decisions differ
based on whether described conditions have been
experienced by the decision maker before or not
(Hadar, 2009). The authors found that decision
making outcomes based on descriptions of pro-
spects that have been previously experienced will
differ from decision making outcomes based on
prospects that have not been previously experi-
enced. Such divergence between decision making
with and without prior experience is attributed to
the information surplus on prospects due to hav-
ing prior experience.
This paper is concerned with personal develop-
ment from a self-guiding point of view. Self-
guiding behavior depends on the readiness of a
person to change habits, and self-perspectives
about which changes are required for the desired
outcome. Boyatzis and Akrivou discuss how per-
spectives of the ideal self, transform into visions
of personal development (Boyatzis, 2006). How-
ever, having personal visions and even increased
awareness of what are causes of personal prob-
lems are not enough to bring about change (Pro-
chaska, 1992). Self-guiding behavior change
needs to assess the prospects of the attempt to
change in order to prepare for different stages of
changing behavior. Blanchard, Zigarmi and Nel-
son discuss the evolution of leadership theories
and in particular the situational approach to lead-
ership, which is relevant to self-guided personal
development (Blanchard, 1993). The authors re-
flect on the changes between the first and second
models of situational leadership. Specifically, the
authors point out that the first situational leader-
ship model categorized people in levels of em-
ployee development” and the first level included
people falsely assumed to be “unwilling and una-
ble” to perform their work tasks. While in the re-
vised (second) model of situational leadership,
the first level of employee development includes
people who are assumed to be “low in compe-
tence” and “have high commitment” (Blanchard,
1993, p. 27).
The current paper equates employee development
with personal development. Behavior change is a
process of both contemplation and action. Con-
templation is necessary for the alteration of ex-
pectations and self-representations, while com-
mitment is necessary to maintain action towards
change.
The second personal development level is being
competent but having low commitment. The cur-
rent research suggests computing, here the use of
an application on a smartphone (mobile) plat-
form, enables people to collect self-data and
compute descriptive statistics. However, such
competence development is not possible without
being committed to the development of such
skills. This paper’s proposed model labels the be-
havioral development from the first to the second
personal development level as computational
competence development.
The third personal development level is being
highly competent and having variable commit-
ment. People’s experience alters their expecta-
tions and perspectives when considering previ-
ously experienced prospects. There is an infor-
mation asymmetry between decision making with
previously experienced and with novel prospects.
This paper’s proposed model labels the behavior-
al development from the second to the third per-
sonal development level as experience develop-
ment.
The fourth personal development level is being
highly competent and having high commitment.
Maintaining a high level of behavioral commit-
ment after having developed high computational
competence depends on the expectations for, and
perspectives on the goals at hand, which are mod-
erated by prior experience. Simply, self-
motivation empowers commitment. Motivation is
an affective state driven by people’s expectations
and their different self-perspectives. Motivation
manifests as behavioral repetition driven by
commitment in a specific behavior. The proposed
model labels the behavioral development from
the third to the fourth personal development level
as behavioral commitment development.
PROPOSED MODEL
Figure 1 depicts a model for self-guiding behav-
ior change based on the development of computa-
tional competence. The proposed model is based
on two hypotheses. The first is that prospect
awareness and computational competence are
positively correlated, and the second is that prior
experience and information asymmetry between
goal expectations and prospect awareness are
negatively correlated.
People set goals based on their expectations and
self-perspectives. People’s experience alters ex-
pectations and self-perspectives; thus, the devel-
opment of experience reduces the information
asymmetry between the consideration of previ-
ously experienced prospects and novel prospects.
The ability to collect self-behavioral data to in-
form expectations and self-perspectives addresses
information asymmetries and discrepancies that
regulate prospect awareness. Prospects are judged
in order to make choices.
Decision-making in real-world situations is usual-
ly concerned with multiple objectives that may be
conflicting with each other to various degrees.
Moreover, rationality in decision-making is mod-
ulating based on situational and personal factors
(Kahneman, 2003; Campitelli, 2010). The situa-
tional leadership theory was briefly discussed in
combination with the principle of information
asymmetry due to prior experience.
This paper proposes a computer-aided, via a mo-
bile application, self-guiding behavioral change
model that follows the prescriptive analysis ap-
proach. Proposed design needs for a mobile ap-
plication are described and to the most part im-
plemented in a working prototype with the aim of
conducting future empirical research with users
of the application to inform design needs and col-
lect feedback as well as feature requests.
PROPOSED MODEL
Fig 1. Self-Guiding Behavior Change Model.
Design Needs
A taxonomy of data-labels that is editable
by the user.
The user can use a date picker to store or
change a daily data value per label.
The user can use a date picker to visit a
view of descriptive statistics per month.
The user is able to navigate in time and
among the types of statistics.
A list of different profiles allows for mul-
tiple user-profiles to be used for data col-
lection.
Encrypted data repository.
No internet access needed.
Import from and export to CSV data files.
A list of different views allows the differ-
entiation of the graphical user interface to
enable different types of data collection
(i.e., health, financial, household, etc.)
Design Limitations
Only one value per day per data-label can
be stored.
Descriptive statistics are computed and
presented per calendar month.
Design Implementation
Fig 2. Example Screenshots of the User Interface.
Automated Descriptive Statistics
Daily records: Each daily value per
month.
Difference from goal: The difference (%)
of each daily value from a predefined goal
value.
Tendency: Smoothed out daily values per
month.
Difference from average: The difference
of each daily value of the month from the
month’s average.
Progressive average difference: The dif-
ference of each daily value from the aver-
age of daily values from the beginning of
each month up to each daily value of the
month.
DISCUSSION
Research Needs
After the development of the proposed applica-
tion reaches the beta stage, then the collection of
empirical data is needed to investigate how often
users store and browse data, as well as their tax-
onomies of data-labels. Such empirical evidence
will inform a human-centered approach to the de-
sign of the user interface so as to offer multiple
views and alternative functionality tailored to dif-
ferent types of data collection.
Features Under Development
The current features under development include:
1) a machine learning algorithm based on naïve
Bayes classifiers for active learning of data-label
statistical salience, and
2) an alternative function that allows to record
multiple datapoints per day and a statistical view
that presents datapoints on a 24-hour chart.
Contribution
This paper contributes a self-guiding, computer-
aided behavior change model to the literature of
personal development by building on the con-
struct of employee development in the theory of
situational leadership, and on the construct of in-
formation asymmetry between decision-making
of previously experienced and novel prospects.
To enable future research, a prototype mobile ap-
plication was developed to allow for downloading
and testing:

An implication for the situational leadership theo-
ry is that employee development is essentially
personal development. However, leaders ought to
provide employees with necessary tools for the
work tasks (developing competence), and place
employees in roles that result in self-motivated
work (developing commitment).
Conclusion
In conclusion, people can increase their cognitive
abilities by using computers and software for data
storage and analysis. However, free or low-cost
tools tend to serve their developers’ intention to
collect data from people’s use of their applica-
tions. Self-guiding behavioral change is possible
when people are self-motivated to pursue change.
However, self-collection of behavioral data can
reveal discrepancies between self-representations
of and actual behavior. The accuracy of factual
information during decision making is critical to
people’s awareness of possible prospects, because
misrepresentations of self-data obscure the con-
sideration of possible solutions as well as the con-
templation on the causes of problem.

Purpose – If the ideal self is the emotional driver of intentional change, the purpose of this paper is to explore the components of a person's personal vision and how it comes from their ideal self. Design/methodology/approach – Based on the concept of the ideal self from intentional change theory, the paper examines a variety of theoretical foundations, from psychoanalytic to positive psychology. Each views the ideal self and its components as deficiencies needing therapeutic intervention or the heights of human experience and intrinsic motivation. Findings – The ideal self is a primary source of positive affect and psychophysiological arousal helping provide the drive for intentional change. Many current frameworks or theories examine only portions of this model and, therefore, leave major components unaddressed. The ideal self is composed of three major components: an image of a desired future; hope (and its constituents, self‐efficacy and optimism); and a comprehensive sense of one's core identity (past strengths, traits, and other enduring dispositions). Originality/value – Intentional change is hard work and often fails because of lack of sufficient drive and the proper intrinsic motivation for it. This model of the ideal self creates a comprehensive context within which a person (or at other fractals, a group or system) can formulate why they want to adapt, evolve, or maintain their current desired state.

OPEN ACCESS: http://www.jmir.org/2013/4/e86/ BACKGROUND: There is increasing interest from academics and clinicians in harnessing smartphone applications (apps) as a means of delivering behavioral interventions for health. Despite the growing availability of a range of health-related apps on the market, academic research on the development and evaluation of such apps is in the relatively early stages. A few existing studies have explored the views of various populations on using mobile phones for health-related issues and some studies are beginning to report user feedback on specific apps. However, there remains little in depth research on users' (and potential users') experiences and views on a wide range of features and technologies that apps are, or will soon be, capable of. In particular, research on young adults is lacking, which is an unfortunate omission considering that this group comprises of a good number of mobile technology adoptors. OBJECTIVE: The current study sought to explore young adults' perspectives on apps related to health behavior change. It sought their experiences and views of features that might support health behavior change and issues that contribute to interest in and willingness to use such apps. METHODS: Four focus groups were conducted with 19 students and staff at a University in the United Kingdom. Participants included 13 females and 6 males with a mean age of 23.79 (SD 7.89). The focus group discussions centred on participants' experiences of using smartphone apps to support a healthy lifestyle, and their interest in and feelings about features and capabilities of such apps. The focus groups were recorded, transcribed, and analyzed using inductive thematic analysis. RESULTS: Study findings suggested that young, currently healthy adults have some interest in apps that attempt to support health-related behavior change. Accuracy and legitimacy, security, effort required, and immediate effects on mood emerged as important influences on app usage. The ability to record and track behavior and goals and the ability to acquire advice and information "on the go" were valued. Context-sensing capabilities and social media features tended to be considered unnecessary and off-putting. CONCLUSIONS: This study provided insight into the opportunities and challenges involved in delivering health-related behavioral interventions through smartphone apps. The findings suggested a number of valued features and characteristics that app developers may wish to consider when creating health behavior apps. Findings also highlighted several major challenges that appeared to need further consideration and research to ensure the development of effective and well-accepted behavior change apps.

Background Smartphones and tablet computers have become an integral part of our lives. One of their key features is the possibility of installing third-party apps. These apps can be very helpful for improving health and healthcare. However, medical professionals and citizens are currently being overloaded with health apps. Consequently, they will have difficulty with finding the right app, and information and features are fragmented over too many apps, thereby limiting their usefulness. Discussion In order to combat health app overload, suppliers of apps need to do three things. One, join the open source movement, so that a few apps can work as gateway to medical information by incorporating information from different sources. Two, standardize content, so that the information provided via apps is readable. And third, in order to prevent information overload from occurring within an app, content should be personalized towards an individual’s characteristics and context. Summary Suppliers of medical information and features need to join the open source movement and must make use of standardized medical information formats, in order to allow third parties to create valuable, mobile gateway apps. This can prevent the occurrence of health app overload. By going along in these trends, we can make health apps achieve the impact on healthcare quality and citizens’ health many of us envision.

In this paper we investigate the claim that decisions from \textit{experience} (in which the features of lotteries are learned through a sampling process) differ from decisions from \textit{description} (in which features of lotteries are explicitly described). We find that the experience-description gap is not as robust as has been previously assumed. We argue that when this gap appears it is driven to a large extent by asymmetries in information concerning which events are possible and which are certain. First, we find that, when experience-based decision makers sample events without error and then are told what outcomes are associated with each possible event, they are risk seeking for low-probability gains and risk averse for high-probability gains, as in description-based decision making. Second, we find that the experience-description gap for low-probability outcomes appears when rare outcomes are never experienced but disappears when: 1) all distinct outcomes are experienced at least once or 2) never-experienced outcomes are described as possibilities. Third, we find that the experience-description gap for high-probability outcomes is pronounced when decision makers previously experience lotteries that both offered the possibility of a zero outcome (which presumably makes them doubt that an always-experienced outcome is certain), but disappears when they have not previously experienced such lotteries.

The Internet has become a major component to health care and has important implications for the future of the health care system. One of the most notable aspects of the Web is its ability to provide efficient, interactive, and tailored content to the user. Given the wide reach and extensive capabilities of the Internet, researchers in behavioral medicine have been using it to develop and deliver interactive and comprehensive treatment programs with the ultimate goal of impacting patient behavior and reducing unwanted symptoms. To date, however, many of these interventions have not been grounded in theory or developed from behavior change models, and no overarching model to explain behavior change in Internet interventions has yet been published. The purpose of this article is to propose a model to help guide future Internet intervention development and predict and explain behavior changes and symptom improvement produced by Internet interventions. The model purports that effective Internet interventions produce (and maintain) behavior change and symptom improvement via nine nonlinear steps: the user, influenced by environmental factors, affects website use and adherence, which is influenced by support and website characteristics. Website use leads to behavior change and symptom improvement through various mechanisms of change. The improvements are sustained via treatment maintenance. By grounding Internet intervention research within a scientific framework, developers can plan feasible, informed, and testable Internet interventions, and this form of treatment will become more firmly established.

Early studies of intuitive judgment and decision making conducted with the late Amos Tversky are reviewed in the context of two related concepts: an analysis of accessibility, the ease with which thoughts come to mind; a distinction between effortless intuition and deliberate reasoning. Intuitive thoughts, like percepts, are highly accessible. Determinants and consequences of accessibility help explain the central results of prospect theory, framing effects, the heuristic process of attribute substitution, and the characteristic biases that result from the substitution of nonextensional for extensional attributes. Variations in the accessibility of rules explain the occasional corrections of intuitive judgments. The study of biases is compatible with a view of intuitive thinking and decision making as generally skilled and successful.

The use of smartphone applications (apps) to assist with weight management is increasingly prevalent, but the quality of these apps is not well characterized. The goal of the study was to evaluate diet/nutrition and anthropometric tracking apps based on incorporation of features consistent with theories of behavior change. A comparative, descriptive assessment was conducted of the top-rated free apps in the Health and Fitness category available in the iTunes App Store. Health and Fitness apps (N=200) were evaluated using predetermined inclusion/exclusion criteria and categorized based on commonality in functionality, features, and developer description. Four researchers then evaluated the two most popular apps in each category using two instruments: one based on traditional behavioral theory (score range: 0-100) and the other on the Fogg Behavioral Model (score range: 0-6). Data collection and analysis occurred in November 2012. Eligible apps (n=23) were divided into five categories: (1) diet tracking; (2) healthy cooking; (3) weight/anthropometric tracking; (4) grocery decision making; and (5) restaurant decision making. The mean behavioral theory score was 8.1 (SD=4.2); the mean persuasive technology score was 1.9 (SD=1.7). The top-rated app on both scales was Lose It! by Fitnow Inc. All apps received low overall scores for inclusion of behavioral theory-based strategies.

How people intentionally change addictive behaviors with and without treatment is not well understood by behavioral scientists. This article summarizes research on self-initiated and professionally facilitated change of addictive behaviors using the key trans-theoretical constructs of stages and processes of change. Modification of addictive behaviors involves progression through five stages--pre-contemplation, contemplation, preparation, action, and maintenance--and individuals typically recycle through these stages several times before termination of the addiction. Multiple studies provide strong support for these stages as well as for a finite and common set of change processes used to progress through the stages. Research to date supports a trans-theoretical model of change that systematically integrates the stages with processes of change from diverse theories of psychotherapy.

Analysis of decision making under risk has been dominated by expected utility theory, which generally accounts for people's actions. Presents a critique of expected utility theory as a descriptive model of decision making under risk, and argues that common forms of utility theory are not adequate, and proposes an alternative theory of choice under risk called prospect theory. In expected utility theory, utilities of outcomes are weighted by their probabilities. Considers results of responses to various hypothetical decision situations under risk and shows results that violate the tenets of expected utility theory. People overweight outcomes considered certain, relative to outcomes that are merely probable, a situation called the "certainty effect." This effect contributes to risk aversion in choices involving sure gains, and to risk seeking in choices involving sure losses. In choices where gains are replaced by losses, the pattern is called the "reflection effect." People discard components shared by all prospects under consideration, a tendency called the "isolation effect." Also shows that in choice situations, preferences may be altered by different representations of probabilities. Develops an alternative theory of individual decision making under risk, called prospect theory, developed for simple prospects with monetary outcomes and stated probabilities, in which value is given to gains and losses (i.e., changes in wealth or welfare) rather than to final assets, and probabilities are replaced by decision weights. The theory has two phases. The editing phase organizes and reformulates the options to simplify later evaluation and choice. The edited prospects are evaluated and the highest value prospect chosen. Discusses and models this theory, and offers directions for extending prospect theory are offered. (TNM)
