Aim To investigate dietitians' perceived adequacy of pre- and
postregistration training in a range of behaviour change techniques,
current main approach to dietary treatment and perceived usefulness of
future training in five core behaviour change modalities.
Method A questionnaire was designed and distributed to all dietitians
registered in the BDA membership base (n = 4202).
Results Three hundred and ninety-four questionnaires were re-
turned. The majority of these respondents had obtained their degree
since 1982 (77%), since when courses were more likely to have
contained a psychological component. Despite the fact that facilitating
dietary behaviour change is a key dietetic role, respondents felt that
they had not received adequate training in behaviour change skills in
their dietetic training. Training was perceived to be most satisfactory in
active listening skills, but this was perceived as barely adequate.
Training was perceived as particularly poor in: applying theories of
cognitive and behavioural therapy (CBT); motivational techniques;
group work skills; and in both theory and skills of relapse prevention.
Although 40% of respondents reported receiving explicitly psycholo-
gically based training, skills-based training (mainly counselling) was
reported by only 25% and was limited by being mainly short 1- or 2-
day courses. Overall, where further training was obtained it was
perceived to be more adequate than that reported within preregistra-
tion dietetic training.
Conclusion Respondents felt that they had not received adequate
training in behaviour change skills in their dietetic training. The
application of CBT, motivational techniques and relapse prevention
was perceived as particularly deficient in training and the majority of
respondents felt that future training would be useful or very useful. In
the current health service climate, where evidence-based practice is
crucial for all practitioners with the emphasis on improved quality of
care with measurable outcomes, research must be funded and
undertaken to support attempts to improve dietitians' effectiveness as
behaviour change agents.

Introduction
Dietitians have traditionally functioned as nutri-
tional advice givers rather than behaviour change
agents. Dietetics originated as a hospital-based
profession with the traditional dietetic interview
being firmly based on the model of the doctor±
patient medical consultation which uses direct
persuasion to get people to change their behaviour
(Hunt, 1995). Dietitians focus on translating
scientific and medical decisions relating to food
and health into terms which everyone can under-
stand (BDA, 1997). In this context, dietitians are
trained how best to teach and advise people about
the important dietary changes that they need to
make rather than how to provide tools to help
people to implement these changes (Rapoport,
1998). Over the last 20 years there has been a shift
from the dietitian acting as a technician delivering
advice to a consultant with expertise in all aspects of
nutrition and dietetics (Judd et al., 1997). This has
been paralleled by a move from practising pre-
dominately within an acute hospital setting to a
more community-orientated base. As a result,
authors have recognized the need for competency
in counselling skills in the dietetics practitioner.
However, in spite of this most dietitians complete
their training without developing specific skills in
behaviour change. The process of facilitating
behaviour change has largely remained in the
domain of applied psychology.
The evidence in support of integrating behaviour
change theory and strategies into dietetic practice is
strong. Studies have shown that nutritional inter-
ventions based on the dissemination of information
are not very effective in bringing about behavioural
change (Glanz, 1985; Shepherd & Stockley, 1987;
Contento et al., 1995). In a review of 217 nutrition
intervention studies, it was found that setting
behaviour change as the goal is a significant factor
in improving dietary practices (Contento et al.,
1995). Effective programmes additionally incorpo-
rated communication and group educational stra-
tegies that were motivating, taught strategies for
behavioural change, included active involvement of
both the individual and the community and
attempted to build health-enhancing environments.
In a more recent review of 76 healthy eating
interventions, the HEA (1997) reinforced these
findings with recommendations that healthy eating
interventions should have a clearly stated theoretical
basis incorporating effective models of communica-
tion and behaviour change, and should adopt a
behaviourally based approach which includes active
involvement of individuals.
The research demonstrates the necessity of
including behavioural methods for effective inter-
ventions, but how important do dietitians perceive
training in behaviour change strategies to be?
Following a survey of dietetic practice, Gilboy
(1994) observed that whilst dietitians have adopted
some counselling strategies, they still lag behind in
the use of adherence-enhancing strategies recom-
mended for behaviour change. Increasingly dieti-
tians themselves have reported the need for
counselling skills training (Isselman et al., 1993).
Adopting a counselling approach and utilizing
counselling skills provides the fundamentals of a
process to help a person to identify problems, assess
needs and promote dietary change. In a BDA
preregistration working group survey examining
structure and content of preregistration education
and training for dietitians, participants perceived
counselling skills as largely absent in courses
(Rogers & Judd, 1996). Communication and
educational methods were considered to be allo-
cated too little time in training by over 50% of
respondents. This has led to recommendations from
the British Dietetic Association/Council for Profes-
sions Supplementary to Medicine Dietitians Board
Joint Working Party that more emphasis is placed
on developing skills in communication and coun-
selling. However, beyond this, specific behaviour
change methods are required to effectively treat
commonly encountered problems, such as obesity.
The British Dietetic Association recognizes that to
offer optimal obesity treatment dietitians must
possess the skills and confidence to help people
through the process of change and equip them to
prevent relapse (BDA, 1997), of which adequate
training is a prerequisite.
The need for training in these methods is
recognized by the profession and if dietitians
themselves desire further training in this area, core
behaviour change training has to be identified and
implemented based on the strengths and weaknesses

of current training. In the first instance, it is helpful
to identify perceived adequacy of current training in
core areas. Such core training areas may include
methods which facilitate the therapeutic alliance
(listening skills), methods which stimulate motiva-
tion for, and reduce resistance to, change (motiva-
tional techniques), strategies for optimizing
behaviour change (cognitive and behavioural ther-
apy) and strategies to help maintain new behaviours
once established (relapse prevention). This survey
aimed to assess how adequate currently practising
dietitians felt that their training in these behaviour
change methods both pre- and post- (where
received) registration had been as a starting point
for further recommendations.
Method
Subjects
In October 1997, a short self-completion question-
naire was mailed to all dietitians registered in the
BDA membership database (n = 4202). Of these,
4029 were based in the UK and 173 were based
overseas. Dietitians were asked to return the
questionnaire by the middle of November. Owing
to resource constraints, no self-addressed envelope
or reminder mailing or follow-up of nonrespon-
dents was undertaken.
Instrument
The questionnaire was designed to elicit informa-
tion regarding perceived adequacy of both pre- and
postregistration training in a range of behaviour
change techniques. The questionnaire consisted of
five sections (Appendix 1): (i) assessed dietetic
training history and any other training received in
psychological interventions; (ii & iii) assessed
perceived adequacy of training (rated on a four-
point likert scale) in five discrete areas of psycho-
logical behaviour change techniques pre- and
postregistration; (iv) asked respondents to identify
their main approach to dietary treatment (Hunt,
1995) eliciting an example of how they would apply
this approach in practice in order to assess the
degree to which this was used to consistently have
the same meaning; and (v) assessed perceived
usefulness (rated on a four-point likert scale) of
future training in the five core behaviour change
modalities addressed in sections two and three.
Statistical analyses
Statistical analyses were carried out using SPSS for
Windows, release 7.5. Valid percentages were used
for reporting results. Content analysis was used to
analyse data in section four.
Results
Questionnaire responses were received from only
394 dietitians, henceforth referred to as respon-
dents, representing 10% of the membership. Levels
of missing data in the different sections vary and so
actual numbers of respondents to each question are
reported.
Training history
Dietetic training
Locations of dietetic training were diverse. The
majority of respondents had been trained in Scot-
land (32%), southern England (28%) and northern
England (26%). The majority of individuals had
qualified by obtaining a BSc degree (39%), a
diploma (35%) or a BSc Hons degree (25%).
Dietetics obtained degree status in 1982 since when
courses were broadened, and were more likely to
have contained a psychological component. The
majority of respondents (77%) had obtained their
degree since 1982.
Perceived adequacy of preregistration dietetic degree/
diploma training
Table 1 shows the perceived adequacy of preregis-
tration training in a range of behaviour change
methods in the 394 respondents.
Perceived adequacy of preregistration dietetic training
in active listening. The modal response for both
reflecting and summarizing skills was barely ade-
quate. Only about one-fifth of respondents per-
ceived their training in this area to be at least
adequate.
Training in behaviour change methods 289

Perceived adequacy of preregistration dietetic training
in cognitive and behavioural therapy (CBT). In
CBT, the modal response was not at all adequate for
seven of the specified techniques, and barely
adequate for theories of behavioural therapy.
Notable exceptions were perceived adequacy for
only two of the techniques: goal setting and self-
monitoring. Training was perceived to be least
adequate in exposure, stimulus control and challen-
ging negative thoughts related to eating.
Perceived adequacy of preregistration dietetic training
in motivational techniques. In motivational tech-
niques, the modal response was not at all adequate
for all techniques specified. Training was perceived
to be least adequate in eliciting motivational
statements and confrontation of conflict regarding
change. It is notable that almost one-quarter of
respondents reported not receiving any training in
motivational techniques.
Perceived adequacy of preregistration dietetic training
in relapse prevention. The modal response was not
at all adequate for all techniques specified. Nearly
half of the respondents perceived training in
theories of relapse prevention and actually mana-

ging high-risk situations to be least adequate. It is
notable that almost one-quarter of respondents
reported not receiving any training in relapse
prevention.
Perceived adequacy of preregistration dietetic training
in group treatment. The modal response was
barely adequate for training in theory and practice
of group treatment.
Other training
Just under half the sample, 195 (49%), completed
the question referring to other training in addition
to their preregistration dietetic training. Although
respondents were asked to name only their other
training in psychological interventions, 354 (90%)
reported having attended a wide range of other
training. This has therefore been included in the
analyses despite not necessarily being totally re-
levant to the question asked. Owing to requesting
course titles of other training received, in some
cases the degree of psychological content in the
named course was unclear as well as how it
compared with other courses. This made reporting
of these data particularly difficult. On the basis of
this limited information, types of training courses
attended were broadly categorized into nine differ-
ent subgroups (Table 2). Number of additional
training courses attended ranged from one to six.
On the basis of this categorization, 147 (42%)
respondents reported attending courses which were
explicitly psychologically related, with 92 (26%)
reporting having attended courses which included
explicitly behaviour change skills-based training.
It was notable that most further training courses
attended that were explicitly skill based were short
1-day or 2-day courses. Very few respondents
reported having attended in depth other training
in behaviour change-based interventions.
Perceived adequacy of dietetic postregistration/other
training
Table 3 refers to the perceived adequacy of further
training in the 195 (49%) respondents who
completed question 3 and reported having attended
this. The table reveals that the majority of
respondents who received other training received

this in active listening skills and were least likely to
have received further training in cognitive and
behavioural therapy or relapse prevention.
Perceived adequacy of other training in active
listening. The modal response for active listening
was adequate, indicating that the majority of
respondents who received additional training in
this area found this to be at least adequate. About
one-quarter perceived their training in this area to
be less than adequate.
Perceived adequacy of other training in cognitive and
behavioural therapy. Training in problem solving,
goal setting and self-monitoring were perceived as
having been covered particularly well. The modal
response for other training in CBT was adequate for
seven of the techniques and barely adequate for
exposure, stimulus control and challenging negative
thoughts related to eating. Similarly to dietetic
training, additional training in exposure, stimulus
control and challenging negative thoughts related to
eating were perceived as having been particularly
poorly covered.
Perceived adequacy of other training in motivational
techniques. The modal response to additional
training in motivational techniques was adequate.

well. On the other hand, theories of motivational
interviewing, eliciting motivational statements and
confrontation of conflict regarding change were
perceived to have been covered particularly poorly.
Perceived adequacy of other training in relapse
prevention. The modal response to additional
training in relapse prevention was adequate. Identi-
fication of high-risk situations was perceived to
have been covered slightly better than actually
managing high-risk situations or theories of relapse
prevention which was not covered at all for almost
one-fifth of respondents.
Perceived adequacy of other training in group
treatment. The modal response to additional
training in group treatment was adequate.
Main approach to dietary treatment
The majority of respondents reported using a
predominantly client-centred approach to dietary
treatment (43%). The next most popular approach
was discussing (29%), then advising (20%), teach-
ing (2%), nondirective (2%) and instructing
(, 1%). A multiple answer indicating the use of a
combination of responses was given by 47% of
respondents.
Three hundred and thirty-five (85%) respondents
gave an example of how they characterized their
practice, e.g. advising means taking a dietary history
and giving information about dietary change to a
patient. Fifty-eight (15%) gave no example. Those
who described `advising' as their main approach to
dietary treatment were more likely to mention
taking a diet history in their example of practice.
Other than that, no central theme emerged within
each category. Two main dilemmas for respondents
emerged across all categories: how to balance the
client's and professional's agendas and the degree to
which it is the dietitians responsibility to prioritize
offering information vs. other interventions when
time is short.
Perceived usefulness of future training
The majority of respondents reported that future
training in active listening, cognitive and beha-
vioural therapy, motivational techniques, relapse
prevention and group treatment would be very
useful (Table 4). Of these, the majority felt that
future training in CBT, motivational techniques and
relapse prevention would be particularly useful.
Discussion
The small sample size means the results must be
interpreted with caution. Compared with other
surveys of dietitians (Hauenstein et al., 1987; Judd
et al., 1997; Cowburn & Summerbell, 1998; Taylor,
1998), the percentage of respondents was low,
although actual numbers of questionnaires received
compare favourably. Results of this survey cannot
therefore be considered as representative of the
profession. Possible explanations of the particularly
poor response rate may firstly be methodological
considerations: the group targeted was not specially
selected for their potential interest in the survey
subject, no self-addressed, prepaid envelope for
return was included nor reminder letters or follow-
up mailings of nonrespondents sent. Secondly, the
recipients of the questionnaire may have been
unfamiliar with the topic and therefore did not
recognize its significance or comprehend what was
being asked. This explanation is supported by

written comments by several respondents who
commented that the survey did not apply to them
as they felt their training in this area was so
deficient.
Despite the fact that facilitating dietary behaviour
change is a key dietetic role, respondents felt that
they had not received an adequate training in
behaviour change skills in their dietetic training.
Training was perceived to be most satisfactory with
regard to active listening skills though this was
perceived as barely adequate. Training was per-
ceived as particularly poor in applying theories of
cognitive and behavioural therapy, motivational
techniques and group work skills and in both theory
and skills of relapse prevention. Although two-fifths
of respondents reported receiving explicitly psycho-
logically based training in addition to their
preregistration training, receiving further explicitly
behaviour change skills-based training (mainly
counselling) was reported by only one-quarter and
was limited by being mainly short 1- or 2-day
courses. Overall, where further training was ob-
tained it was perceived to be superior to that offered
within preregistration dietetic training. Certain key
areas were perceived as particularly deficient in
training across the board, notably the application of
CBT, motivational techniques and relapse preven-
tion.
Many respondents felt constrained by short
appointment duration and were confused about
whether their core role and responsibility was to
provide information, to establish and develop
patients' motivation for change, or to teach
behaviour change strategies which could be im-
plemented by the patient. In general, many
dietitians feel under pressure to see large numbers
of patients. In addition, some may feel that they do
not have adequate time to assist their patients in
effecting change. Dietitians need to find the balance
between size of caseload and clinical effectiveness
and to have the confidence to implement such a
strategy. Nonetheless, a skilful dietitian can opti-
mize effectiveness within even a very restricted
amount of time.
The majority of respondents felt that future
opportunities for training would be useful or very
useful. Most people reported `client-centred' as
their main style of treatment but there was no
consistency in the techniques reported in use under
this category. This suggests that respondents were
not familiar enough with the meanings of the
specified labels or that the terms were not essentially
valid to use. It is likely that education about the true
meaning of some of these approaches was absent
from their training.
In principle, should dietitians be trained in
counselling and behaviour change strategies? There
is enough suggestion from a broad range of research
that CBT is more likely to work than direct
persuasion. It is well known that compliance with
medical advice is poor and with dietary advice it is
often poorer (Glanz, 1979). Some suggest this may
be related to the limitations of the medical model
(Davidson et al., 1987). Using knowledge and
expertise to supply clients with a set plan to follow
is only likely to be adequate for a very small number
of people (Vickery & Hodges, 1986; Glanz &
Eriksen, 1993). Therefore, the information giving
and instructional aspect of dietetic practice should
incorporate motivational and behavioural compo-
nents.
Does the evidence support the case for training
dietitians in a range of different core behaviour
change methods specified in this survey? Most
evidence existing regarding the effectiveness of these
different methods comes from outside the dietetic
profession. A review of using a patient-centred
approach has shown positive health outcomes for a
range of different medical settings (although not
dietetic) in 16 out of 21 studies (Stewart et al.,
1995). This approach has been shown to increase
patient satisfaction after seeing a doctor, improve
compliance with medication, decrease patients'
concerns, decrease raised blood pressure, improve
postoperative surgery and decrease blood sugar in
people with diabetes mellitus (Orth et al., 1987;
Putnam & Lipkin, 1995; Stewart et al., 1995).
Training physicians in communication skills
through problem-defining skills or emotion-hand-
ling skills has been shown to improve the process
and outcome of care without lengthening the visits
(Roter et al., 1995). The evidence for the effective-
ness of CBT is mainly within the context of treating
mental health problems (American Psychological
Association, 1995) and obesity and eating disorders
(Wing, 1992; Fairburn et al., 1993; Wilson, 1995).

In the limited literature in which dietitians have
been trained in CBT, they have been shown to
achieve similar results in weight management as
behavioural psychologists (Paulsen et al., 1976;
McReynolds et al., 1976). The evidence for the
effectiveness for relapse prevention and motiva-
tional interviewing has mainly been demonstrated
within the field of addictive disorders (Miller &
Rollnick, 1991; Marlatt, 1995).
However, if we make the evidence the only
justification for the use of particular methods, we
are missing the importance of the moral and ethical
dimension of treatment. It could be argued that the
basic tenets of patient- or client-centred medicine,
which incorporates six key components (explora-
tion of both the disease and the illness experience,
understanding of the whole person, finding com-
mon ground between client and practitioner,
incorporating prevention and health promotion,
enhancing the relationship and being realistic),
constitute the fundamentals of good practice and
should be key in training any health professional
engaged in helping others change (Stewart et al.,
1995).
In principle, dietitians should be trained in
behaviour change methods and they themselves
recognize a gap in their skills and training. Limited
evidence exists as to whether, in practice, training
dietitans in these methods actually improves their
effectiveness ± the signs are promising, but only
with further research can the question confidently
be answered.
Recommendations
1 The role of the dietitian needs to be redefined as
an agent for behaviour change as well as a
consultant nutritional expert.
2 In the current health service climate, where
evidence-based practice is crucial for all practi-
tioners with the emphasis on improved quality of
care with measurable outcomes (Department of
Health, 1997), research must be funded and
undertaken to support attempts to improve dieti-
tians' effectiveness as behaviour change agents.
3 Consequently, dietitians should review the
degree to which the profession has an adequate
foundation in integrating behaviour change strate-
gies into dietetic practice both at pre- and
postregistration level.

Training in psychological interventions ± a survey
Dear Colleague,
The purpose of this survey is to identify the
psychological techniques that dietitians might be
trained in to help their client's change their eating
behaviours. These techniques are known by a
variety of terms so we have defined some of them.
We would be very grateful if you would complete
the questionnaire. We plan to publish the results
from this survey and to use them to help identify
training needs for dietitians. Thank you very much
for your interest, support and time in completing
this questionnaire,
Yours sincerely,
Lorna Rapoport and Gill Cowburn
