New communication technologies offer novel possibilities for the prevention ofmental illness, in which geographical and psychosocial distances often hamperhelp-seeking. This paper introduces ES[S]PRIT, an Internet-based eating dis-orders (ED) prevention programme for university students. The programmefollows a stepped-care approach combining various support components ofincreasing intensity. These components comprise psychoeducation, symptommonitoring, supportive feedback, peer support, and professional online counsel-ling. Participants who develop substantial ED symptoms during their participa-tion are referred to the University Student Counselling Center. We outline theunderlying concepts and various components of the programme and report firstexperiences with the approach in a sample of German college students. Finally,potentials of the approach are highlighted and the need for further research isstressed.

Introduction
College entry is considered an important transitional phase that is often experienced
as a stressful period causing psychological distress in students (Dyson & Renk, 2006;
Rosenthal & Schreiner, 2000; Soeder, Bastine, & Holm-Hadulla, 2001). Not
surprisingly, elevated prevalence rates of psychiatric disorders have been found in
college student samples (Dyrbye, Thomas, & Shanafelt, 2006; Seliger & Brahler,
2007). Consequently, adolescents who are at risk of the development of a mental
illness might need special support during this difficult phase of leaving home and
entering college to prevent onset of such disorders. However, development of targeted
prevention programmes for this population is still in its infancy.
In particular, symptoms of disordered eating as well as full-syndrome eating
disorders (ED) display common and serious health problems among college-age
women. Thus, many prevention programmes have been developed in the field of ED.
Searching for risk factors, several studies have proven excessive weight and shape
concerns to be associated with the onset of both subclinical and clinical level EDs in
young women (e.g. Stice, 2002). Consequently, ED prevention programmes have

focused on the reduction of such overconcern with weight and shape aiming at a
reduction of the incidence of ED (e.g. Stice & Shaw, 2004).
While the majority of the first generation ED prevention programmes failed to
achieve changes in critical attitudes and behaviours, Internet-based approaches have
produced more promising findings. A recent study shows that the programme
‘Student Bodies’, an eight-week, Internet-based cognitive-behavioural intervention,
caused a substantial reduction in weight and shape concerns in college-age women at
risk for the development of an ED. The study also provided first evidence for the
potential of the programme in the prevention of ED onset in two subgroups of
participants (Taylor et al., 2006).
Over the past years, Internet-based programmes have become widely used in the
treatment and prevention of mental disorders (Carlbring & Andersson, 2006; Myers,
Swan-Kremeier, Wonderlich, Lancaster, & Mitchell, 2004; Patten, 2003; Pull, 2006).
They have the advantage of being accessible from everywhere and at any time,
providing support for participants for whom access to traditional care might be
difficult due to time constraints or other barriers. Many individuals suffering from
mental disorders seek help late, which increases risk for a chronic course of illness.
Technology-enhanced programmes may offer acceptable support to such individuals
in an early phase of their illness, thus allowing for early interventions on a low
intensity level. Additionally, such programmes may help to decrease barriers to
seeking traditional psychotherapeutic treatment if necessary.
Moreover, Internet technology enables clinicians and researchers to monitor
psychological impairment and symptoms in large participant samples at reasonable
time and cost which allows them to provide timely interventions if necessary. Taking
advantage of these options, we developed and piloted a targeted prevention and early
intervention programme (‘ES[S]PRIT’) for college students who are at risk of the
development of an ED.
The intervention strategy of ES[S]PRIT
In contrast to existing prevention programmes, ES[S]PRIT uses a stepped-care
approach by combining several support components of various intensity. Addition-
ally, the programme follows an individualised strategy by matching intensity of
support to participants’ needs. The underlying assumption holds that the participants’
symptoms develop heterogeneously during their participation in the programme:
while the majority of participants will not develop severe ED symptoms during their
participation, others may experience periods in which they need more intense online
support and yet others will need face-to-face counselling and potentially even more
intense psychotherapeutic treatment.
Consequently, ES[S]PRIT monitors relevant factors continuously throughout the
participation in the programme so that users can receive additional interventions in
phases when they need them. This flexible procedure is in contrast to most other
prevention programmes that provide a fixed amount and frequency of support to all
participants (e.g. by offering a fixed number of sessions that are supposed to be
completed one after the other in weekly sequence).

The components of ES[S]PRIT
When individuals first enter the ES[S]PRIT website they are invited to complete a
short online screening questionnaire consisting of the Weight Concerns Scale (WCS;
Killen et al., 1994) and the Short Evaluation of Eating Disorders (SEED; Bauer,
Winn, Schmidt, & Kordy, 2005). After entering their data, they receive an automatic
feedback according to the results. The screening aims at identifying individuals who
are either at risk of developing an ED or who already show mild ED symptoms. If
screened as at risk, individuals are invited to participate in the ES[S]PRIT
programme. Individuals who either do not display any risk of the development of
an ED or report severe ED symptoms and/or undergo current treatment for an ED
are not invited for participation. The complete inclusion and exclusion criteria are
displayed in Figure 1.Individuals eligible for participation are invited to register to the programme by
entering their e-mail address and a username and password. However, all individuals
(independent of whether they participate as registered users or not) can access the
comprehensive information material on the ES[S]PRIT website. This material
includes information on the various forms of ED, their precursors, early signals
of ED and self-help strategies. These contents were provided with support of the
German Federal Centre for Health Education (BZgA, 2007). All registered
participants also have access to the moderated ES[S]PRIT Internet forums where
they can exchange information, and discuss whichever topics they want. Participants
may use the forum to support each other, share experiences and give each other
advice. The contents of the forums are checked by a member of the ES[S]PRIT team
for appropriateness of messages every day. Inappropriate postings, such as messages
including pro-anorectic contents are deleted.
Users who register themselves for participation in ES[S]PRIT automatically enter
the supportive monitoring and feedback programme. Assuming that the participants’
well-being and symptoms change in different ways and at varying speed over time,

the continuous monitoring of relevant factors and behaviours is of high importance
in ES[S]PRIT. Thus, beginning immediately after their registration, participants
receive a weekly reminder via e-mail asking them to complete an online monitoring
questionnaire. This questionnaire includes the SEED (Bauer et al., 2005) and eight
questions assessing the following four dimensions: body dissatisfaction (e.g. ‘How
satisfied have you felt in your body over the past seven days?’ 1�very satisfied;
4�very dissatisfied), overconcern with weight and shape (e.g. ‘Has your eating
behaviour/your weight/your shape had a negative impact on your quality of life over
the past seven days?’ 1�definitely no; 4�definitely yes), unbalanced nutrition and
dieting (e.g. ‘On how many days over the past week have you eaten in a balanced
way?’ 1�every day; 4�never), as well as binge eating and compensatory behaviours
(e.g. ‘On how many days over the past week have you used one or several of
the following means due to a fear of gaining weight: laxatives, vomiting, excessive
exercising?’ 1�never; 4�daily). Monitoring data assessment and feedback are
managed by the software ‘Web-Akquasi’ which was developed for the purpose of
outcome monitoring (Percevic, Lambert, & Kordy, 2004).The main purpose of the monitoring programme is to track participants’
impairment throughout their participation in ES[S]PRIT. It allows for an early
identification of deteriorations and critical periods. Additionally, all participants
receive immediate automatic feedback via e-mail according to their answers of the
monitoring questions. For this purpose, a comprehensive pool of feedback messages
was formulated and integrated into the monitoring programme. The feedback follows
the rationale that had been developed within an intervention using text messaging in
the aftercare treatment of bulimia nervosa (Bauer, Percevic, Okon, Meermann, &
Kordy, 2003). Each of the four above-mentioned dimensions is divided into a
functional and a dysfunctional range. From week to week, a participant can in each
dimension change in four different ways: improve (from the dysfunctional range to
the functional range), deteriorate (from the functional to the dysfunctional range),
stay in the functional range or stay in the dysfunctional range. Each time a
participant completes the monitoring questionnaire, the programme automatically
determines the pattern of change out of these 256 possibilities (4�4�4�4). Then,
one feedback text is selected by chance out of the pool of 10 to 15 pre-formulated
statements for this specific type. Sixteen additional feedback categories were createdfor the first assessment when no comparison to earlier assessments is possible, which
results in a total of 272 different feedback categories. The feedback messages were
formulated according to the following principles: first, the messages provide social
support to participants by signalling interest in their well-being and expressing
concern in case of deteriorations. Second, they give advice on how participants can
counteract negative developments in their eating behaviour and their attitudes
towards weight and shape. In Table 1 some examples of feedback messages are given
for different patterns of change.
In case a participant reports severe deterioration (according to pre-defined
criteria) in the monitoring, an e-mail is sent automatically to the online counsellor
(see below) who in turn would contact the participant via e-mail. All registered users
are also invited to participate in online counselling sessions via Internet chat. Chat
technology is used in two different ways: 1) on a monthly basis, users can participate
in group chat sessions which are guided by a clinician, where participants can ask
general questions concerning ED, treatment options, etc., or share experiences withother participants; 2) additionally, users can register for individual chat sessions to
330 S. Bauer et al.
meet with a clinician on an individual basis to discuss more private questions that
they might not feel comfortable asking in the group setting. To do so, participants
browse an online reservation tool and register for a 30-minute chat session. The
online counsellor automatically receives an e-mail with the date of the chat session
and the username of the participant. Prior to the chat session the counsellor will then
log on to the monitoring software Web-Akquasi and check all information available
for this participant (e.g. course of impairment in the monitoring questionnaires). As
mentioned above, the online counsellor will automatically get an e-mail in the case
that a user reports severe impairment in the weekly monitoring questions. He would
then contact this participant via e-mail inviting her or him for an individual chat
session to clarify whether more intense support is needed. In general, the aim of the
online counselling is to provide support to participants and to give them advice on
what they could do to feel better. However, if the online counsellor realises that
online support is not intense enough, students are referred to face-to-face support
at the Student Counselling Center at the University of Heidelberg. If face-to-face
counselling is not sufficient, the counsellor will discuss with the participant the
options of outpatient or, if necessary, inpatient psychotherapeutic treatment.
In summary, the support tools offered within ES[S]PRIT range from online self-
help via psychoeducation, peer support in the forums and automatised feedback in
the monitoring programme, to group support in guided chat sessions, up to
individual counselling in chat sessions, and, if deemed necessary, referral to the
University Counselling Center for face-to-face counselling.

Inclusion and exclusion criteria
Depending on the initial screening, participants receive a feedback message and are
allocated to a specific user group. A specific feedback message was designed for each
endpoint of the decision tree (see Figure 1). Participants who are excluded are not
directed to the registration area. ES[S]PRIT was conceptualised as a prevention and
early intervention programme for college students who have an increased risk of the
development of an ED. Due to this fact, individuals who already undergo treat-
ment for ED and individuals with substantial ED symptoms are not invited for
participation in the programme. Individuals who do not display any risk � neither in
their WCS nor in their SEED scores � are allowed to register for the message board
but cannot use further ES[S]PRIT functionality.
Preliminary findings
ES[S]PRIT was announced for the first time in an online university newsletter at the
end of January 2007. The first participant registered on 25 January. In early
February, ES[S]PRIT was announced in a regional newspaper and in the last week of
February, posters were placed in students’ cafeterias, offices and bill-boards in
Heidelberg.
By the end of April 2007, 357 persons filled in the screening questionnaire. One
hundred and sixty-six (47%) of these were students, 124 (35%) were enrolled at
Heidelberg University; 279 (78%) of the screenings were filled in by females. The
mean age was 27.4 years (SD�11.1, Median�24), and the mean Body Mass Index
(BMI) amounted to 23.0 (SD�5.45). Twenty-nine individuals (8%) underwent
treatment for an ED. The mean SEED AN Total Severity Index (AN TSI) was 0.83
(SD�0.52, Median�0.75), and the mean SEED BN Total Severity Index (BN TSI)
was M�0.78 (SD�0.77, Median�0.5). Thus, the SEED scores of the sample were
higher than those of a non-clinical sample, and lower as compared to a clinical
sample (see Bauer et al., 2005). Table 2 gives a summary of the results of the screening
procedure.According to the criteria mentioned above, 181 individuals (51%) were invited to
register for full access to the programme. Twenty-nine individuals were excluded
because they already underwent an ED treatment. Another 65 individuals scored too
high according to the ED symptom screening procedure. Therefore a total of 94
individuals (26%) were excluded from the programme due to too severe ED
problems. Eighty-two (23%) displayed no risk and were offered only access to the
message board. We further compared the SEED scores of the individuals invited for
participation with those who were not invited due to too severe impairment. The
results indicate that the screening procedure and participation rules were appropriate
for an ED prevention programme. Individuals excluded (N�94) had a mean AN TSI
of 1.21 (SD�0.63, Median�0.75) which equals the impairment found in clinical
samples. The mean BN TSI of the excluded subgroup was 1.39 (SD�0.88, Median�1.25) which scores between clinical (mean BN TSI�2.14) and non-clinical samples
(mean BN TSI�0.2). Individuals who were allowed to register (N�263) showed
substantially less impairment. Their mean BN TSI was 0.57 (SD�0.59, Median�0.5) and their mean AN TSI was 0.69 (SD�0.39, Median�0.75).
Forty-four individuals (12%) finally registered for the programme and received an
account for the personal area. The mean age of this group was 31.0 years (SD�12.7)
332 S. Bauer et al.
and they had a BMI of M�25.1 (SD�6.3). One participant’s access was limited to
the message board area because he was in the no-risk group. Participants with full
access filled in the monitoring questionnaire 163 times (M�3.8, SD�3.6, range�1�13) which is 83% of the scheduled monitoring questionnaires given on average 3.6
weeks of participation (SD�3.9, range�1�13). Seven participants ended participa-
tion after on average 6.9 weeks (SD�1.4).
Conclusions
College entry is considered to be one of the major life events for young people, often
associated with serious mental problems. In addition to psychological distress, such
problems may also negatively impact students’ achievements. For example, Hysen-
begasi, Hass, and Rowland (2005) report a strong influence of psychological
impairment on the academic productivity of university students. Both reasons
underscore the need for targeted and indicative preventive initiatives in college
student populations.
Over the past years, an increasing number of technology-enhanced prevention
programmes has been developed. Despite some promising recent findings (Taylor
et al., 2006), a systematic review found no overall effects of Internet-based prevention
programmes on ED symptoms (Newton & Ciliska, 2006). The authors state a need
for further refining the strategies applied in online prevention programmes for ED.
The stepped-care approach of ES[S]PRIT might be a first step in this direction. The
continuous monitoring of critical attitudes and behaviours allows clinicians to track
participants’ impairment in weekly intervals. The system automatically alerts the
online counsellor in case of critical developments, allowing for early interventions in
case of severe impairment. The supportive monitoring and feedback programme and
the participants’ ability to use the various support components flexibly according
to their needs display the biggest innovation of ES[S]PRIT as opposed to other
prevention programmes which often follow manualised approaches and mostly
require that all participants use the same amount and intensity of support.
Especially in the field of prevention, this traditional strategy seems questionable.
The majority of participants will not develop an ED despite their increased risk, and
thus might not need an intense intervention. As long as research fails to reliably
predict the heterogeneous courses of symptoms � i.e., ultimately who will develop an
ED and who will not � it might be better to follow a population-based stepped-care
approach, providing low-intensity support for a large number of individuals, allowing
them to access more intense care as soon as they need it. ES[S]PRIT is the first
prevention programme aiming at such a match between participants’ needs and the
type and intensity of support while reaching out for a large number of individuals.

The results of the pilot study indicate that there is a clear need for preventive
action in the student population. Within a few weeks, more than 350 individuals
showed interest in the programme and completed the screening questionnaire. Most
of them displayed either a risk of the development of an ED or reported substantial
impairment. The screening algorithms proved valid with regard to the extent of
impairment in different subgroups.
Twenty-six percent of all individuals who underwent the screening were excluded
from the programme either due to too high ED symptom self-reports, or because
they were already in treatment. This number demonstrates the need for online
support for individuals struggling with ED symptoms. So far, ES[S]PRIT offers only
information material and addresses where these people might seek help. Moreover,
in the context of ED, often the adverse effects of the Internet, such as Pro Ana
websites, have been highlighted (e.g. Norris, Boydell, Pinhas, & Katzman, 2006). It is
important to counteract these developments by offering broad platforms to
disseminate healthy attitudes and social support.
The pilot phase shows that ES[S]PRIT is technically feasible. Given that most
parts of the programme are automated, it is possible to use it in large samples at
reasonable time and cost. However, in our view it is of high importance to connect
such offers to the traditional counselling and health care system. ES[S]PRIT is
offered by the Student Counselling Center of the University of Heidelberg and thus
extends the reach of this institution. It is known that individuals with ED-related
problems often seek help (face-to-face) very late. We assume that programmes such
as ES[S]PRIT might help to get individuals into more intense programmes (face-
to-face counselling or psychotherapeutic treatment if necessary) earlier.
At this early stage, many questions remain to be addressed by future research.
First, the acceptance of the various components needs to be studied. For example, it
is unclear why a substantial proportion of individuals who displayed a risk of an ED
and who were invited to participate in the programme decided not to do so. However,
the participants so far completed 83% of the scheduled monitoring questionnaires.
This finding indicates that individuals who register for the programme have a good
compliance concerning the monitoring component. In future studies we will
systematically study attrition from the programme and if necessary aim at developing
additional components to increase the potential to keep individuals in the
programme. Indicators for modifications of the programme will be available from
the evaluation questionnaires that participants will be asked to complete after three
months of participation as well as at their programme termination.
In the longer term, it is necessary to systematically evaluate the effectiveness of
ES[S]PRIT in a controlled study. Additionally, it will be relevant to investigate the
differential effectiveness of the various support components as well as the impact of
ES[S]PRIT on participants’ help-seeking behaviour, i.e. for example whether
ES[S]PRIT helps to provide early face-to-face interventions for participants who
develop substantial ED impairment during their participation.
