6Brief History of Internet Gambling Research
7Concerns about the Internet
8Facebook Addiction Disorder (FAD)
- 1. The first thing is tolerance. This refers to
the need for increasing amounts of time on
Facebook to achieve satisfaction and/or
significantly diminished effect with continued
use of the same amount of time. They often have
multiple Facebook windows opened at any one time.
3 is usually a sign and over 5 you're helpless.
2. After reduction of Facebook use or
cessation, it causes distress or impairs social,
personal or occupational functioning such as
wondering why your Vista is so fast and improved
etc. These include anxiety obsessive thinking
about what is written on your wall on Facebook
etc. 3. Important social or recreational
activities are greatly reduced and or migrated to
Facebook. Instead of sending an email you post a
message on your friends page about canceling a
lunch appointment. You now stop answering your
phone call from your Mom and insist she should
contact you through Facebook chat. 4. This is
getting serious if you start kissing your
girlfriend's home page or a VRML virtual walk
through a park is your idea of a date.5. Your
bookmark takes 20 minutes just to scroll from top
to bottom or 8 of 10 people in your friend's list
you have no idea of who they are. 6. When you
meet people you start introducing yourself by
following "see you in Facebook" or your dog has
its own Facebook profile. You invite anyone
you've met and any notifications, messages and
invites reward you with an unpredictable high,
much like gambling.

- Youtube Addiction Disorder (YAD)
- Google Search Addiction Disorder (GSAD)
- Widget Addiction Disorder (WAD)
- Twitter Addiction Disorder (TAD)
- Blackberry Addiction Disorder (BAD)
10Speculation about Internet Gambling
- Internet gambling is prolific and growing
- Growth increases exposure
- Increased accessibility makes internet gambling
more addictive than other types of gambling - No standardized product safety regulations to
protect vulnerable populations
11State of Knowledge Internet Gambling
- Very little peer-reviewed and published empirical
research - Theoretical propositions and opinion papers
represent most of the professional discussion
surrounding this topic - The available empirical findings are from studies
that use variations of retrospective self-report
methodology
12Methods Procedures
- Used PubMed PsycINFO databases to identify the
gambling literature that included - Internet and gambling
- Three inclusion criteria for studies
- Published between 1903 2007 in peer-review
journals - Have the word gambling and Internet in one of
four citation fields title, keyword, abstract,
and text - Have some relevance to the field of gambling
studies - 30 publications met these criteria
13- We classified these 30 into three publication
groups - Commentaries - articles with no empirical data
- Self-report surveys - articles with empirical
data provided by participants - Actual Internet gambling - articles with data
describing actual Internet Gambling

15Internet Gambling Publications
16"...self-report appears to have all but crowded
out all other forms of behavior. Behavioral
science today... mostly involves asking people to
report on their thoughts, feelings, memories, and
attitudes.... Direct observation of meaningful
behavior is apparently passe" (p.
397).Baumeister, R. F., Vohs, K. D., Funder,
D. C. (2007). Psychology as the science of
self-reports and finger movements whatever
happened to actual behavior? Psychological
Science, 2(4), 396-403.
17Solutions
- Approaches need to go beyond retrospective
self-report and include objective measures, such
as actual Internet gambling behavior - Using actual behavior avoids the difficulties
inherent in self-report (National Research
Council, 1999) as well as the need to compress
the information about actual behavior occurring
during long intervals into a few summary
descriptions elicited by survey questions
18Internet Gambling Risk and Resource?
- Internet Gambling provides unique opportunities
for the study of gambling behavior and problems. - Unlike land-based gambling, the very technology
that makes Internet gambling a potential risk
allows for the study of actual real-time gambling
behavior.
19bwin / Division on Addictions Research
Collaborative
20BWin / DOA Collaborative Objectives
- To address the dearth of scientific information
on Internet gambling, bwin and the DOA have
entered into a seminal research collaboration
relying substantially on data provided by bwin
subscriber gaming activity. - The principal goal of this project is to
empirically examine Internet gambling. - A second goal is to provide Bwins current
corporate social responsibility department with
evidence-based research, tools, and programs
about problem gambling, so that they can
effectively protect the health of the general
public as well as the industry.

25Types of Bets
- Fixed-Odds
- bets made on the outcomes of sporting events or
games in which the amount paid for a winning bet
is set by the betting service - relatively slow-cycling betting propositions the
outcomes of a bet are generally not known for
hours or even (in the case of cricket matches)
days - Live-Action
- bets made on propositions about outcomes within a
sporting event (e.g., which side will have the
next corner kick or whether the next tennis game
in a match will be won at love by the server) - More rapidly cycling betting propositions
provides many, relatively quick-paced, betting
propositions posed in real-time during the
progress of a sporting event

49Caveat
- We dont know how much disposable income these
betters had available - Therefore, it is not possible to calibrate the
social harm these losses might have caused
50Conclusion
Despite the caveat about discretionary funds, the
results do suggest problem gambling is not as
common among Internet sports bettors as the
speculations and the consequent conventional
wisdom suggested.
51Inside the Virtual Casino Internet Casino
Gambling
52Sports Betters Revisited
- Most people play moderately
- 1 of the sample played differently from the
rest, making a median of 4.7 bets every other day - Most peoples play adapted, following the
prototypical public health adaptation curves - 1 of the sample did not adapt
53Casino Play Hypotheses
- Individuals betting in virtual casinos will
exhibit riskier behaviors than observed among
Internet sports bettors and poker players. - Example more excessive loss patterns or time
spent gambling - Moderate and consistent gambling among the
majority of the population - A small minority (i.e. 5 or less) will exhibit
excessive gambling behavior.
54Internet Casino Gamblers
- Ever played Casino Games (n 8,472)
- 20 of Longitudinal Sample
- Excluded (n 4,250)
- Gambled 3 or fewer times (4,225)
- Gambled with promotional funds (10)
- Gambling began less than one month before the end
to the study (15) - Final sample (n 4,222)
55Demographics
- Average age 30
- 93 male
- Spread out across 46 countries
- Only 1 gender difference

Wagering decreased as losses increased shows
rational decision making
This is high because the outcome of casino
gambling is a function of chance and the house
odds
Shows day-to-day betting consistency
58Casino vs Sports Gambling
Frequency of play for each game type
Cost of play for each game type
- Even though casino spending was higher than
spending on other types of games, the cohort of
casino bettors played less frequently than the
sports bettors. - The observation that casino game bettors incur
larger losses at each gambling session compared
to sports bettors is consistent with our
hypothesis that casino-type games offer an
additional risk for players.
59Implications
- Few people play internet casino games
- 18 of bwin subscribers played, half of whom
never played more than three days. - The typical daily cost of casino gambling is
considerably larger than the sports betting costs
of this cohort.
60Total stakes wagered on casino games
61Gambling behavior of extreme 5 and 95 subgroups
of casino bettors
62Cost of Casino Gambling
- The top 5 of casino gamers lost a significantly
smaller percent of their total wagers compared to
the rest of the casino gamblers (t 21.0, ndf
871, P lt 0.001).
63Limitations
- Casino gambling might not have been so popular
because bwin is primarily a sports betting
service. - Females are underrepresented, although their
betting behavior did not differ much from that of
males.
64Responsible Gambling Efforts in the Virtual World
65Unique Opportunities for Intervention
- Tracking software for early identification of
people who are at-risk for developing problems - Limit-setting
- Time
- Losses
- Deposits
- Pop-up messaging and email by request or by design
66Corporate Social Responsibility
- Corporate Deposit Limits
- Self-limitation of Deposits
67Deposit Limits
- bwin Interactive Entertainment, AG imposes
corporate deposit limits on its subscribers and
allows subscribers to set specific deposit
limits, if they are lower than the corporate
limits - Subscribers who try to deposit more than the
allowed amount receive from bwin a notification
message about the attempt to exceed the deposit
limit and bwin rejects the attempted deposit
Broda, LaPlante, Nelson, LaBrie, Bosworth,
Shaffer, 2008
68Expectations
- Users who receive a notification constitute a
group of extremely engaged gamblers - Excessively large betting, high loss or high
frequency of gambling - Receiving a notification acts as a warning sign
- Gambling behavior would attenuate after such
notification
69Sample Description
- 160 (0.3 5 women) of the sample received at
least one notification (Exceeders) - Exceeders received between 1 and 267
notifications (M14 notifications)
70Gambling Behavior Before After Notification
- After receiving notification
- Exceeders did not reduce their number of active
betting days - Exceeders patterns of losses did not change
- Exceeders increased their average size of bet
- Exceeders decreased the average number of bets
per active betting day
Exceeders made fewer, larger bets per active
betting day after notification
71Summary
- In general, the mere existence of deposit limits
might serve as a harm reduction device - Exceeding established limits can serve as an
indicator for heavy betting behavior and large
overall losses - Notification systems for exceeding deposit limits
do not completely curtail betting behavior, but
are associated with changes in betting strategy - Moving away from smaller more frequent bets to
larger more infrequent bets
72General Comment on Notification Systems
- Apparent need to re-think the use of notification
systems as harm reduction devices for those
at-risk for excessive patterns of betting - Similar limitations for other such systems
- People who were given feedback that BAC exceeded
legal limits have been subsequently observed to
drive - Drivers who receive speed tickets are at
increased risk of receiving subsequent speeding
tickets - Smokers who receive biomedical feedback do not
initiate appreciable changes toward quitting
smoking
73Self-limitation of Deposits
- bwin Interactive Entertainment, AG allows
subscribers to self-impose deposit limits that
are lower than those defined by corporate policy - Attempts to exceed self-imposed deposit limits
are blocked by the company software system
Nelson, LaPlante, Peller, Schumann, LaBrie,
Shaffer, in press
74Expectations
- Participating in the self-limitation system could
be an indicator of potential disordered gambling - Users who self-limit constitute a group of
extremely engaged gamblers - Self-limitation will promote healthier gambling
behavior - Decreased stakes, bets, and frequency of betting
75Sample Description
- 567 (1.2) of the sample participated in the
self-limitation system (Limiters) - 7 of these individuals placed these limits
before they made their first bet - 11 ceased betting completely after they
self-imposed limits
76Limiters versus Others Pre-limit Comparisons
- Limiters played a greater diversity of gambling
games - Limiters bet on more days within their active
betting period - Limiters placed more bets per day
- Limiters wagered less money per bet
- Limiters and others did not differ in terms of
- Total wagered, net loss, percent lost
77Results Games Played
78Gambling Behavior Before After Self-Limitation
- Limiters behavior after imposing limits
generally moved in the direction of fewer bets - For example, for fixed odds betting, limiters

80Summary
- Limiters were more active bettors than others
- Place more bets, bet on more days during active
period, bet on greater diversity of products - If self-limitation is a sign of disordered
gambling, involvement might be as important to
indicating gambling-related problems as
expenditures
81General Limitations
- Limiting resources are only helpful if people can
access them easily
82General Limitations
- Interventions will only work if the message gets
through to the target
83General Limitations
- Real behavior measures provide an unbiased
assessment of actual Internet gambling, but
cannot be used to determine rates of
gambling-related problems - Healthy changes in gambling behavior for our
sample do not preclude unhealthy changes in
gambling behavior, or other behavior, on other
websites or activities
84Concluding Thoughts
- The Internet provides some unique opportunities
for harm reduction devices that might be executed
with some success - Internet gambling is likely to continue to grow
during the next decades, and empirical
examination is necessary to the development of
safe and effective responsible gaming
intervention efforts
