Case history and initial assessment
T
HE PARTICIPANTwas a female ama-
teur judoka who was ranked within the
top six in Great Britain at the start of the
intervention. The participant trained three
times a week. Preliminary interviews with the
participant revealed that she lacked self-effi-
cacy (self-confidence) for training and com-
petition after having a year out from
competing due to the break-up of a long
standing personal relationship. Although
self-confidence is a term often used by ath-
letes to describe a belief in their ability to be
successful, psychologists typically refer to the
construct of self-efficacy. Self-efficacy is
defined as ‘…a belief in one’s capabilities to
organise and execute the courses of action
required to produce given attainments’
(Bandura, 1997, p.3). The term self-efficacy
reflects situation-specific self-confidence (i.e.
the belief to successfully execute a specific
move in judo) as opposed to global self-con-
fidence (i.e. confidence in your ability as a
judoka) which is more of a personality trait
or disposition (Cox, 2002). Bandura (1986,
1997) proposes that performance accom-
plishments (i.e. experiencing success), vicar-
ious experiences (i.e. viewing a skilled
performer), verbal persuasion (i.e. positive
self-talk) and emotional arousal (i.e. being
emotionally ready and optimally aroused)
are all essential elements that determine an
individual’s level of self-efficacy.
Following a discussion with her coach the
participant had decided to return to training
and competition and to ‘give it one more
go’. Since returning to training the partici-
pant reported that she felt ‘inferior’ and ‘did
not deserve to be on the mat’ as well as expe-
riencing thoughts of failing during training
and competition. This was often the case
when the participant was faced with familiar
opponents. The participant believed that
these thoughts stemmed from a poor run of
form prior to her break from competition.
Because of her low level of self-efficacy the
participant believed that she had become
‘soft’ on the mat, which prevented her hav-
ing the necessary ‘edge’ to compete at a high
level. The participant’s performances were
poorer than past seasons and this was caus-
ing her worry and frustration.
The participant wished to have a greater
belief in her ability prior both to training
and competition. She also wanted to per-
form well in the upcoming National Trials
(which were three months away at the start
of the study) and be more consistent
throughout competitions during the season.
To provide a baseline measure of the type of
Using hypnosis to increase self-efficacy:
A case study in elite judo
Jamie B. Barker & Marc V. Jones
An elite female judoka reported a debilitating level of self-efficacy relative to judo performance. Pre- and
post-intervention data were collected via a specifically designed self-efficacy questionnaire (SEQ) that con-
sisted of seven items relating to good judo performance. An intervention programme consisting of eight hyp-
nosis sessions was conducted. These sessions comprised the delivery of general ego-strengthening,
sport-specific ego-strengthening and self-hypnosis suggestions. A pre-performance routine using self-hypnosis
was developed for use prior to training and competition. Data from the SEQ were inconclusive, as there
was a trend towards higher self-efficacy prior to the intervention. However, the participant reported a pos-
itive perception of hypnosis and believed that the use of hypnosis resulted in increased self-belief during both
training and competition. Although further research is needed the findings of this case study suggest that
hypnosis can be used to enhance self-efficacy in sport performers.
mental strategies employed by the partici-
pant the Test of Performance Strategies
(TOPS; Thomas, Murphy & Hardy, 1999)
was administered. In addition, a specifically
developed Self-Efficacy Questionnaire
(SEQ) was completed within 24 hours of the
training session or competition. The SEQ
consists of seven items relating to good judo
performance based on the micro-analytic
approach to self-efficacy assessment outlined
by Treasure, Monson and Lox (1996). The
seven items consisted of the following:
aggression, gripping, newaza (arm locks/
strangles), upping the pace, attacking first,
positive attacking and focus. The participant
noted how certain she had felt of completing
each move successfully in her last training
session/competition. As such, the question-
naire required the participant to recall the
level of self-belief they felt they had about
successfully completing the identified per-
formance-related items during actual per-
formance. A rating of 100 indicated high
certainty and a rating of 0 indicated no belief
in her ability to complete the tasks. Baseline
data were collected over nine training ses-
sions and competitions.
Problem formulation
The intake interview indicated that the par-
ticipant reported a debilitating level of self-
efficacy prior to performance. In addition,
the participant’s mean score on the SEQ was
46.91 (S.D. = 4.01). The results from the pre-
intervention TOPS revealed that the partici-
pant used relaxation strategies much more
frequently in competition as opposed to
training. In addition, she indicated that the
use of imagery and self-talk in training and
competition was infrequent and that she
engaged in a lot of negative thinking when
performing in competition (see Table 1).
Self-efficacy is regarded as a strong and
consistent predictor of successful individual
athletic performance (Kane, Marks, Zaccaro
& Blair, 1996; Treasure, Monson & Lox, 1996).
Self-efficacy levels are proposed to impact per-
formance by determining levels of motivation
which will be reflected in the challenges indi-
viduals undertake, the effort they expend and
levels of perseverance (Bandura, 1997). Self-
efficacy judgements have also been shown to
influence certain thought patterns (e.g. goal
intentions, worries, causal attributions) and
emotional reactions such as, pride, shame,
happiness, and sadness (Bandura, 1997).

38 Sport &Exercise Psychology Review Vol 1 NoThere is a plethora of research docu-
menting the effectiveness of a variety of men-
tal techniques in facilitating self-efficacy
within the sport domain (Zinsser, Bunker &
Williams, 2001). Evidence can be found sup-
porting the use of goal setting (Kane et al.,
1996; Locke & Latham, 1990; Schunk, 1991),
positive feedback (Escarti & Guzman, 1999;
Schunk, 1995), imagery (Feltz & Riessinger,
1990; Jones, Mace, Bray, McRae & Stock-
bridge, 2002) and self-talk (Feltz, 1988;
Wilkes & Summers, 1984).
In the current study hypnosis was used as
an intervention to enhance self-efficacy.
Hypnosis can be defined as ‘…an induced
temporary condition of being in a state that
differs mentally and physiologically from a
person’s normal state of being’ (Weitzenhof-
fer, 2000, p.221). Suggestions are given dur-
ing hypnotic trance to alter perceptions,
thoughts, feelings, sensations which facilitate
a long-term change in behaviour (Unestahl,
1983). Recent research by Pates and col-
leagues has focussed on the effectiveness of
hypnosis in generating an appropriate psy-
chological state for competition (Pates,
Cummings & Maynard, 2002; Pates & May-
nard, 2000; Pates, Maynard & Westbury,
2001; Pates, Oliver & Maynard, 2001). These
researchers have been consistently able to
induce a flow state and demonstrate
enhanced performance across a wide variety
of tasks. Despite these positive findings,
there is a need for further research to evalu-
ate the efficacy of hypnosis on psychological
variables such as self-efficacy, in order for
hypnosis to be considered as a performance
enhancing strategy by the sport science com-
munity (Pates, Cummings &Maynard, 2002;
Taylor, Horevitz & Balague, 1993).
Intervention
Initially, the participant revealed that she was
sceptical about the use of hypnosis as a per-
formance enhancing technique. This was a
result of viewing stage hypnosis which
resulted in the construction of a negative
perception. Therefore, prior to the hypnotic
intervention the participant was presented
with information about hypnosis, the nature
of a trance state, and the procedure that
would be followed when inducing a hypnotic
trance. This was to alleviate any misconcep-
tions about hypnosis, to facilitate rapport
(Heap & Aravind, 2001) and alleviate any
anxiety the participant was experiencing
about the use of hypnosis (Hammond,
1990).The participant was also informed
that an appropriately qualified individual
would deliver the hypnosis sessions (all ses-
sions were delivered by the first author, who
holds a Certificate in Clinical Hypnosis from
the London College of Clinical Hypnosis).
Following this, the participant provided
informed consent to participate in the inter-
vention.
The hypnotic intervention commenced
with three sessions that adopted general ego
strengthening suggestions. The sessions
lasted approximately 70 minutes each and
were consultant led. Each session consisted
of the following phases: induction, deep-
ener, post-hypnotic suggestions (PHS) and
awakening. These sessions introduced the
individual to hypnosis and presented them
with suggestions that would stimulate posi-
tive thoughts and behaviours (Hammond,
1990). Then, three sessions that adopted
judo specific ego strengthening suggestions
were undertaken. Again each session lasted
approximately 70 minutes, were consultant
led, and comprised of an induction, deep-
ener, PHS and awakening. An original script
was developed with the athlete to make it
more personal and specific to judo training
and competition. Here terms and phases
that the participant was familiar with were
used. The post-hypnotic suggestions used are
reported in Figure 1 overleaf. The final part
of the intervention comprised two sessions
(each 80 minutes in length and consultant
led) focussing on developing the partici-
pant’s ability to use self-hypnosis. The self-
hypnosis sessions contained the following
phases; induction, deepener, PHS (focussing
on installing self-hypnosis suggestions) and
awakening. This stage provided the partici-
pant with instructions on how to undertake
self-hypnosis when alone. In addition, sug-
gestions focussing on feelings and sensations
were presented (Liggett, 2000). Following
this session the participant was instructed on
how to induce self-hypnosis and was asked to
practice twice daily and to keep a diary doc-
umenting their experiences as well as the
depth of trance they achieved. Frequency of
practice was measured by the completion of
a practice chart which was collected from the
participant each week. This revealed that she
had adhered to her twice daily practice of
self-hypnosis. From these sessions a pre-per-
formance routine that used self-hypnosis was
developed. The routine comprised using
self-hypnosis two hours prior to each train-
When you practice and compete…you will no longer think nearly so much about yourself…you will
no longer dwell nearly so much upon yourself and your difficulties…and you will become much
less conscious of yourself…much less pre-occupied with yourself…and with your feelings…
Every time you practice and compete…your nerves will become stronger and steadier…more
composed…you will become much less easily worried…much less easily agitated…much less easily
fearful and apprehensive…much less easily upset…you will find it much easier to ‘step up’ on the
mat prior to judo performance…
When standing on the mat prior to judo practice and competition you will be able to think more
clearly…you will be able to concentrate more easily…you will be able to give your whole undivided
attention to whatever you are doing…to the complete exclusion of everything else…and you will
find it easier to ‘step up’…
Every time you practice or compete…youwill become and remain… emotionally much calmer…
much more settled…much less easily disturbed…much more dominant…more assertive…stronger
and powerful…more so than you have felt for a long time…
Every time you practice and compete…youwill become and youwill remain…less tense…both
mentally and physically…
And asyou become…and asyou remain…less tense when standing on the mat prior to and during
practice and competition…you will develop much more confidence in yourself…more confidence in
your abilityto do…not only what you have…to do each day…but more confidence in your ability
to do whatever you oughtto be able to do…without fear of failure…without fear of
consequences…without unnecessary anxiety…without uneasiness…
Because of this…every time you practice or compete… you will feel more and more
independent…more able to stick up for yourself…to stand on your own feet to hold your
own…more assertive and powerful… no matter how difficult or trying things may be…
Every time you practice and compete…you will feel a greater feeling of personal well being…a
greater feeling of personal safety and security…more than you have felt for a long, long time…
And because all these things will begin to happen…exactly as I tell you they will happen…more
and more rapidly…powerfully…and completely…with every treatment I give you…you will feel
more confident when standing on the mat prior to both training and competition…
You will consequently become much more able to rely upon…to depend upon…yourself…your own
efforts…your own judgement…your own opinions…in both practice and competition…
Figure 1: Post-hypnotic sport specific ego strengthening suggestions
ing session for a period of four weeks. The
routine was then adapted for the partici-
pant’s first competition of the season when
the participant would use hypnosis at the fol-
lowing times: the night before competition,
morning of the event and upon arrival at the
venue. Here the participant would find a
place that was quiet and where they could
comfortably position themselves without dis-
tractions, and then they would close their
eyes and focus on deep, slow and controlled
breathing. After approximately five minutes
the participant would present themselves
(internally) with positive suggestions that
focussed on self-belief, success and concen-
tration (similar to those outlined in Figure
1). Then the participant would awaken by
opening their eyes and moving their fingers
and toes. The participant later reported that
she was able to find quiet places to conduct
her routine and that she was able to a attain
a deep level of trance when using self-hyp-
nosis in this situation.
Throughout the intervention regular con-
tact was maintained with the participant,
which comprised telephone calls or meetings.
This was not only to facilitate adherence and
outcome, but also to monitor the participant’s
views and feelings about the use of the mental
skill (i.e. hypnosis) and adapt the intervention
if required (Shambrook & Bull, 1999).
Results
In order to analyse the effectiveness of the
intervention 16 post-intervention data points
(SEQ) were collected. The TOPS was also
completed again and a post-intervention
interview was conducted to assess the partic-
ipant’s perception of the intervention. It is
worth noting that data point 25 in Figure 2
represents participation in the National Judo
Trials. In addition, 10 follow-up measures six
months after the intervention were also col-
lected. Data were analysed via visual analysis
and a comparison of pre and post descriptive
statistics. Visual analytical techniques were
used in order to eliminate small effects and
hence promote large intervention effects
(Baer, 1977).
Figure 2 highlights that self-efficacy
increased (during pre- and post-interven-
tion phases) with each training session that
was completed. However, post intervention
and during the follow-up phase this
increase is more gradual and constant. The
participant indicated that during session
17, her mind was filled with positive
thoughts and images about successful per-
formance for the first time since returning
to training and competition. The data also
indicate that the participant experienced
her highest level of self-efficacy (up to that
point) for the National Trials (data point
Figure 2: Pre- and Post-Intervention and 6-Month Follow-Up Self-Efficacy (SEQ) Scores
25). Visual analysis of the pre- and post-
intervention mean scores indicated a mean-
ingful difference across the SEQ scores
(SEQ pre M = 46.91, SD = 4.01; SEQ post M
= 52.52, SD = 2.88).
The post-intervention TOPS scores
revealed an overall improvement in the indi-
vidual’s use of psychological strategies dur-
ing training and competition. The
improvement centred upon an increase in
the use of imagery and self-talk in training
and competition and a reduction in the use
of negative thinking during competition
(Table 1). For example, the participant
reported visualising successful performance
during training session 17.
A post-intervention interview with the
participant revealed that she now held the
intervention in positive regard. She
reported that the intervention helped her
to have greater belief in her ability (i.e. an
increased frequency of positive thoughts),
to feel more relaxed and focused prior to
training and competition and also that
hypnosis had increased her self-belief in
other life situations (e.g. job interview and
a university presentation). Although the
participant had highlighted that she was
sceptical regarding the use of hypnosis at
the beginning of the intervention, she
indicated that she would now recommend
the technique to other athletes. Further-
more, she reported that there had been a
definite change in the belief she had in
her own ability, stating that the ‘self-belief
is now back’. In short, the hypnosis had
become an integral part of her judo
preparation.
The participant finished sixth in the
National Trials, which was slightly lower than
she had aimed for (her goal was to finish
within the top five). However, she reported
feeling pleased with how she had performed
in the competition and overall she was
pleased with her recent performances and
reported being appreciative of the interest
and enthusiasm shown by the consultant in
aiding her development.
Discussion
The study examined the effects of a hypnotic
intervention on an elite judoka experiencing
low levels of self-efficacy during training and
competition. As the number of training ses-
sions increased so did the participant’s level
of self-efficacy. Accordingly, it seems that
training experiences over the study period,
such as performance accomplishments and
vicarious experiences, have contributed to
this increase (Bandura, 1997). However, evi-
dence from the participant implies that hyp-
nosis encouraged a greater use of positive
self-talk and imagery during training and com-
petition. This supports Bandura’s (1986) pre-
diction that verbal persuasion is a significant
factor impacting upon an individual’s level
of self-efficacy. In addition, the participant
felt the hypnotic intervention had allowed
her to feel more (appropriately) psychologi-
cally prepared for competition. Therefore,
supporting research by Pates and colleagues
who successfully used hypnosis to induce
flow states in participants across a variety of
sport related tasks (e.g. Pates & Maynard,
2000; Pates, Cummings &Maynard, 2002).
The use of educational material relating
to hypnosis and the development of a close
rapport with the participant (via telephone
calls and meetings) was thought to aid the
participant’s adherence to the intervention
protocol. From a practical point the estab-
lishing of rapport and reducing the impact
of negative perceptions towards hypnosis
cannot be underestimated in facilitating a
successful outcome (Hammond, 1990; Heap
& Aravind, 2001).
The participant reported a positive per-
ception towards hypnosis and attributed the
use of hypnosis to her having greater self-
belief in her judo ability both in training and
competition. In addition, she also indicated
that her increase in self-efficacy had trans-
ferred into other life tasks. The participant
also successfully incorporated hypnosis into
her judo preparation and reported it being
an integral part of her training schedule six
months after the study.
One potential limitation of the study is the
inability to state that hypnosis was the contrib-
utory factor in facilitating a change in behav-
iour. It appears that the participant
experienced an increase in self-efficacy as she
began training following her return to compe-
tition. However, the participant did report that
the hypnosis was helpful in enhancing her self-
efficacy. Further research is needed within
sport psychology to consistently document the
effect of hypnosis on self-efficacy and other
psychological variables that impact sport per-
formance, such as anxiety and motivation.
