| Abstract |
| |
| Objective: Because the practical application of motivational interviewing (MI) for health practitioners has been
highlighted as a limitation to the approach, the purpose of this pilot study was to assess the impact of a one-day
training workshop in MI applied through Co-Active life coaching (CALC) skills on health care practitioners’ perceived
competence, autonomy and attitudes toward facilitating health-behavior changes. |
| |
| Methods: A pre-test/post-test multiple baseline design was used with 10 health care practitioners. Data was
collected beginning 25 days prior and for 4 weeks post-training. Participants received a 7.5 hour interactive workshop
in January 2011. The Perceived Competence Scale, the Perceived Autonomous Motivation Scale and the Nutrition
in Patient care Survey were adapted and administered to assess attitudes toward facilitating health-behavior changes
in clinical care. |
| |
| Results: Significant increases in perceived competence [Cohen’s effect size d=4.61], perceived autonomy
[d=1.62], practitioner efficacy [d=2.22], and behavior change in routine care [d=1.69] were reported and remained
clinically significant four weeks after the training. |
| |
| Conclusion: Participation in this applied workshop was effective and should be explored further with a larger
group. |
| |
| Practice Implications: This training improved practitioners’ comfort to counsel behavior changes and may be a
useful training model for health professionals. |

| Introduction |
| |
| The majority of health conditions causing disease and death
in Canada and western society are, at least in part, behaviorally modifiable
[1-3]. Usage of primary health care consultation in Canada
is high [4]. In 2005, 77% of Canadians aged 18 to 64 years reported
that they had consulted a general practitioner in the previous year.
Unfortunately, recent research suggests that lifestyle counseling by
physicians is minimal [5-7]. The lack of behavior change counseling
may be explained in part by the minimal amount of time physicians
and patients spend together during a primary care visit, often not
more than 10 minutes [8,9]. Other health care professionals such as
pharmacists, nurses, and dietitians have been identified as particularly
accessible, and interact with patients for a longer duration during visits
[8,10] placing them in a good position to provide motivational support
[11,12]. Consequently, non-physician health professionals are in a key
position to be involved in behavior change counseling [13-15]. |
| |
| One communication technique receiving increased support for
assisting health practitioners with behavior change conversations
is Motivational Interviewing (MI) [16]. MI is used to resolve
ambivalence and a growing body of evidence supports the position
that MI principles are effective for activating various health-related
behavior changes in individuals including lowering dietary fat intake
[17], improving adherence to medication regimes [18], enhancing
compliance with exercise programs [19], as well as several other health related
improvements [20,21]. |
| |
| Although MI is well described, and has been widely researched
in the health care field, health care professionals receive varied and
often minimal training towards its practical application [22]. Research indicates that a major challenge with MI in a setting such as daily
clinical practice is the lack of understanding about how to integrate the
concepts into practice [23]. This may explain the inconsistent results of
MI interventions [23-25]. |
| |
| Co-Active Life Coaching (CALC) [26] is a theoretically grounded
behavior change method [27]. Recent research has found that a
probable reason for much of CALC’s effectiveness lies in the fact that its
tools provide tangible methods to bring the tenets of MI to practical use
[27,28]. The current study was part of a mixed-methods investigation
to explore qualitatively and quantitatively, the impact of a one-day
CACL workshop on practitioners’ experiences of behavior change [29]. |
| |
| The purpose of this study was to assess quantitatively the impact
of a one-day training workshop in MI applied through CALC skills
on health care practitioners’ perceived competence, autonomy and
attitudes toward facilitating health-behavior changes among patients
in daily clinical practice. It was hypothesized that improvements
would be reported in attitudes, perceived competence, and autonomy
to facilitate health behavior changes among patients. |
| |
| Methods |
| |
| A pre-test/post-test multiple baseline design was employed to
examine the impact of MI via CALC tools training workshop on
various aspects of participants’ attitudes toward behavior change
facilitation in daily clinical practice. Ten health care practitioners from
various specialties volunteered to take part in the study; all were female;
five registered nurses; two pharmacists; two social workers; and one
dietitian. Participants ranged in age from 26- 65 years with 60% between
ages 38-55. Ninety percent of participants had 10 or more years of fulltime
experience in their current specialty and one participant had two
years’ experience. Two participants had previous MI training which
consisted of one hour or less. Full participant demographic details are
presented in Table 1. |
| |
|
Table 1: Demographic Information of Health Care Practitioners (n=10.) |
|
| |
| Participants were eligible if they were health care practitioners
working full-time and had an interest in improving their patient communication
and facilitating behavior change in their patients. |
| |
| Two certified Co-Active coaches, with extensive experience
facilitating workshops focused on the application of MI through
CALC for health care practitioners, provided a seven and a half hour
interactive training workshop. Together, this team has conducted many
MI/CALC workshops (n > 20), most geared to multidisciplinary health
care professionals. Health care practitioners were recruited within
the Thames Valley Family Health Team and attended the training
workshop in MI via CALC tools. |
| |
| Participants engaged in between one and five baseline
measurements with the first baseline questionnaire completed 25
days prior to participation in the workshop. Upon completion of
the workshop, participants filled out the same questionnaires again,
immediately after the workshop. Thereafter, at weeks one (seven days)
and four (30 days) post-workshop questionnaire were completed by
each participant. A visual timeline outlining the study structure and
data collection period is provided in Figure 1. |
| |
|
Figure 1: Step by step timeline of questionnaire administration pre- and
post-workshop. Twenty-five days prior to the workshop, two participants, 01
and 02, completed baseline assessments in the form of questionnaires. For
participants 01 and 02 the baseline questionnaires were completed every
five days until the workshop date for a total of five baseline measurements.
Participants 03 and 04 completed the first baseline measurements 20 days
prior to the workshop and every five days until the workshop date for a total
of four baseline measurements. Participants 05 and 06 began baseline
questionnaires 15 days prior to the workshop for a total of three baseline
measurements, and so on.After participation in the workshop, all participants
completed the assessment questionnaires at the end of the training day. Post
workshop questionnaires were completed at seven days and 30 days post workshop
(one and four weeks). These were completed individually by each
participant at each time point. Note. The baseline questionnaires and post assessment
questionnaires are identical. |
|
| |
| Multiple baseline single subject design |
| |
| This study utilized a multiple baseline single subject research design
to determine consistency in practitioners’ self-reported motivation,
efficacy, and competency towards working with patients to facilitate
health behavior changes prior to the intervention [30,31]. Multiple
baseline measurement methodology has been shown to be both reliable
and effective in assessing experimentally the types of changes under
investigation in this study [30,31]. |
| |
| Measures |
| |
| Perceived competence scale (PCS): The Perceived Competence
Scale (PCS) [32] was adapted and used to assess participants’
competency to facilitate behavior changes among their patients. This is
a previously validated, short questionnaire based on self-determination
theory with an internal consistency value of 0.8 [32-34]. Items on the
PCS are written to be specific to the relevant behavior or domain being
studied and thus an adaptation was made so that the scale would
address perceived competence to facilitate health behavior changes. |
| |
| Perceived autonomous motivation scale: The Perceived
Autonomous Motivation Scale [35] measured practitioners’ level of
perceived internal motivation to pursue behavior change counseling
among their patients. The scale is validated and reliable and has been
used in a recent study investigating physician motivation to counsel
tobacco dependent patients to quit [35]. This scale was adapted to
reflect behavior counseling in clinical practice. |
| |
| Adapted nutrition in patient care survey (NIPS): The Nutrition
in Patient care Survey (NIPS) [36] was adapted to address practitioners’
attitudes toward facilitating health behavior changes in routine
clinical care. NIPS is a validated tool containing five subscales to
assess nutrition in routine care, clinical behavior, practitioner patient
relationship, patient behavior/motivation and practitioner efficacy
[36]. This tool has good internal consistency and test-retest reliability.
The test-retest reliability for the subscale ‘Nutrition in routine care’
has been shown to be 0.80 when tested on 107 medical students [36].
For ‘Physician-patient relationship’ the reliability was reported at 0.55.
The reliability is 0.50 and is 0.64 for ‘Patient behavior/motivation’ and
‘Physician efficacy’ respectively. This scale is considered useful to predict
patient care practices and to evaluate research on clinical or education
interventions [36]. Four of the NIPS subscales questions were adapted.
The only adaptations were that the words ‘nutrition counseling’ was
changed to ‘behavior change facilitation’ and the word ‘physician’ was
changed to ‘health care practitioner’ to address the topic of behavior
change facilitation. The subscales are entitled: a) Behavior change in
routine care; b) Practitioner-patient relationship; c) Patient behavior/
motivation; and d) Practitioner efficacy. |
| |
| The responses to each statement on the NIPS scale were scored on
a Likert Scale where responses ranged from 1 (strongly disagree) to 5
(strongly agree). Item 6 on the practitioner-patient relationship scale:
“Patients need specific instructions about how to change their behaviors”
was changed to be reverse scored because the MI applied with CALC
approach views the client as being fully competent to identify their own
answers and solutions to challenges, and practitioners are encouraged
to use probing questions rather than advice-based behavior change
methods [26,37]. Item 3 on the practitioner efficacy scale: “For most
patients, health education does little to promote adherence to a healthy
lifestyle” was changed from being reverse scored to being scored as is,
for the same reason as above. |
| |
| Data analysis and interpretation |
| |
| The data was plotted on graphs (Figure 2 and Figure 3 included
as supplementary) for each participant individually. Kazin [31] describes the use of visual inspection to analyze graphs for changes in
measures involving a very small sample size, as demonstrating statistical
significance in trends with low numbers poses a challenge. A change in
mean reflects each participant’s average level of perceived competence/
autonomy/etc., and whether it changed over the baseline period and/
or after the intervention. Cohen’s statistical method for examining the
degree of effect of an intervention on dependent variables was used via
the rule for effect size [38]. Cohen operationally defined a small effect
as d=0.2, an effect that is not noticeable to the human eye; medium
effect, d=0.5 is noticeable to the unaided eye of a trained researcher
or clinician; and large effect, d=0.8, is noticeable to the untrained eye
such as a study participant. Cohen’s rule for interpreting effect size was
used to objectively evaluate participants’ pre-post attitudes on the four
sub-scales of the adapted NIPS scale and perceived competence and
autonomy to facilitate behavior change among patients in routine care.
For this study, it was determined that evidence of a large effect on the
above outcome measures would best support the conclusions that a
clinically significant change had occurred as a result of the intervention
(as this would represent a change that was noticeable to the study
participants). |
| |
| Results |
| |
| Individual effect sizes were calculated for each participant. These
effect sizes were averaged to give an overall best estimate of effect.
Scores for each participant were graphed and analyzed using visual
inspection for the Perceived Competence Scale and the Perceived
Autonomy Scale and will also be presented. |
| |
| Perceived competence |
| |
| The maximum score possible on the Perceived Competence Scale
[32] was 35 and participants’ scores for this study ranged from 10 to 32
with higher scores indicating greater perceived competence to facilitate
behavior change among patients in routine care. |
| |
| Individual effect sizes for the perceived competence scale ranged
from d=1.73 to 20.82 and the average of the individual effect sizes was
d=4.61. This effect size indicates a clinically significant improvement in
participants’ perceived competence to facilitate behavior change after
completion of the training. Furthermore, visual inspection reveals an
increase in each participant’s scores for perceived competence. This
data is presented in Figure 2 (included as supplementary). |
| |
| Perceived autonomy |
| |
| The maximum score possible on the Perceived Autonomy Scale[35]
was 28 and scores for this study ranged from 18 to 28 with higher scores
indicating greater perceived autonomy to facilitate behavior change
among patients in routine care. |
| |
| Individual effect sizes for the Perceived Autonomy Scale ranged
from d=0.00 to 4.08 and the average of the individual effect sizes was
d=1.62. This effect size indicates a clinically significant improvement
in participants’ perceived autonomy to facilitate behavior change after
completion of the training. Furthermore, visual inspection reveals an
increase in the majority of participants’ scores for perceived autonomy.
This data is presented in Figure 3 (included as supplementary). It
should be noted that the highest possible score on this scale is 28
and two participants consistently scored themselves at 28 during the
baseline period, and thus there was no room to show a possible increase
after the intervention period. |
| |
| Adapted NIPS scale |
| |
| Scale ‘Behavior change in routine care’ had a maximum possible
score of 40. Participants’ scores in this study ranged from 28 to 40 with
higher scores indicating more positive attitudes towards facilitating
behavior change in routine care. ‘Practitioner-patient relationship’
had a maximum possible score of 40. Scores for this scale ranged
from 23 to 39. Scale 3: ‘Patient behavior motivation’ had a maximum possible score of 15 and scores for this scale ranged from three to 12.
‘Practitioner efficacy’ had a maximum possible score of 30. Scores in
this study ranged from 17 to 26 with higher scores indicating more
positive attitudes towards the efficacy of health care practitioners to
help facilitate behavior changes among patients. |
| |
| NIPS effect sizes: Participants scores for ‘Practitioner efficacy’
revealed a large increase (Cohen’s d=2.22] with individual effect sizes
ranging from d=0.73 to d=4.24. The overall effect for this scale was
d=2.22. |
| |
| Individual effect sizes for the ‘Behavior change in patient care’
scale ranged from d=-0.71 to 9.53 and the average of the individual
effect sizes was d=1.69. Participants’ scores on the ‘Practitioner-patient
relationship’ scale revealed a moderate increase (Cohen’s d= 0.61].
Individual effect sizes for this scale ranged from d=-1.87 to d=11.24.
Effect size of scores for attitudes towards ‘Patient behavior/motivation’
revealed individual effect sizes ranging from d=-2.83 to d=1.47 with
an average overall effect of d=-0.48, indicating a medium decrease.
Participants’ scores for ‘Practitioner efficacy’ revealed a large increase
(Cohen’s d = 2.22] with individual effect sizes ranging from d = 0.73 to
d = 4.95. |
| |
|
| The overall effect sizes for ‘Practitioner-patient relationship’ and
‘Patient behavior/motivation’ did not show clinically significant
changes. The effect sizes for the ‘Practitioner efficacy scale’ and
‘Behavior change in patient care’ indicated a clinically significant
improvement in participants’ attitudes towards behavior change
counseling in daily clinical practice after completion of the training
intervention. Individual effect sizes and averages for each scale of the
adapted NIPS scale are listed in Table 2. |

| Discussion |
| |
| The objective of the present study was to determine whether
participation in an seven and a half hour MI via CALC tools training
workshop improved health care practitioners’ perceived competence,
perceived autonomy, or attitude towards behavior change in routine
care as assessed through four scales: a) Practitioner efficacy; b)
Behavior change in routine care; c) Patient behavior/motivation;
and d) Practitioner patient relationship. The major findings were
that perceived autonomy, perceived competence, attitude toward
practitioner efficacy to facilitate behavior change and attitude towards
behavior change in routine care improved after participation in the
training. These improvements were still clinically significant four
weeks after the training workshop. |
| |
| There are several important study limitations that must be considered when interpreting the results. First, given the voluntary
nature of the study, the presence of selection bias is a concern.
Participants who volunteer for this training may have had a high
motivation to learn and implement new techniques and are not
necessarily representative of all health care practitioners. Second, all
measures were self-reported, thus reporting biases cannot be ruled
out. Third, the small sample size reduced the power of the study and
precluded the ability to examine more nuanced relationships among
various subgroups of study participants (e.g., by specialty or gender).
Finally, even though several clinically significant findings did emerge,
and methods were employed to isolate the impact of the training itself,
attributing these positive changes solely to the training intervention
would be inappropriate, given that no control group was used [39]. |
| |
| Practice implications |
| |
| These findings are important because they clearly demonstrate that
practitioners are more likely to engage in behavior change conversations
with patients if they feel more capable and amenable to do so, and these
conversations will increase the likelihood that patients will engage in
healthier choices/ behaviors. For example, in the work by Williams et al.
[35], who studied both physicians and non-physicians’ predictors and
motivations to counsel patients about smoking cessation, the authors
reported that improvements in perceived competence and perceived
autonomy predicted changes in counseling behavior [35]. Perceived
autonomy is of particular significance as the self-determination theory
[40] proposes that a change in perceived competence only affects
motivation when the changes are experienced as autonomous [35].
Therefore, the results of this study suggest that after the MI/CALC
workshop, participants felt more autonomously motivated to engage
in behavior change conversations with patients and thus, may engage
in this activity more often. |
| |
| Successfully incorporating MI into a setting such as daily clinical
practice is not well understood currently and studies report mixed
results [23-25]. This may be due to the lack of understanding about how
to integrate the concepts into practice [23]. Co-Active Life Coaching
[26] tools can provide tangible methods to bring the tenets of MI to
practical use [28] and training health care practitioners in such tools
may help increase the amount and effectiveness of behavior change
counseling. Up until the implementation of this study, the utility of an
MI workshop using CALC tools on practitioners’ attitudes, perceived
competence, and motivation to facilitate behavior change in patients
had not been researched. Research evaluating MI training suggests skill
gains are inconsistent and practitioners often do not achieve desired
competency levels [41]. In sharp contrast, the findings from this study
provide a preliminary understanding of the utility of this type of MI training that incorporates specific CALC skills to ameliorate health
practitioners’ attitudes toward and perceived competency in working
with their clients. |
| |
| Behavior-related illnesses are a major health issue for North
Americans and people around the world, and research must continue
to evaluate innovative approaches to assist health care practitioners
in facilitating effective behavior change counseling. Despite the
limitations of this study, MI applied via CALC tools training shows
promise as a strategy to improve health care practitioners’ incentive
to address behavior change in daily clinical practice. Future research
should focus on a larger scale study and include more objective
measures of practitioner counseling behavior. |
