Valuing Questionnaire

ACT’s emphasis on values
“…creative hopelessness, defusion, connecting with self,
acceptance, contact with the present moment, and valuing
must lead to actual concrete differences in the client’s
behaviour that service those valued ends”
(Strosahl et al., 2004)
“While ACT allows for symptom alleviation, it is not a main
target or the therapeutic goal. Rather the focus is on what
we call broadband outcomes. Such outcomes are about
helping the client move in life directions that they truly care
about”
(Eifert & Forsyth, 2005)
“All ACT techniques are eventually subordinated to helping the
client live in accord with his or her chosen values.”
(Hayes et al.,1999, p.205)
Values assessment in ACT
research to date
 Values measures not used as primary
outcome measures in most ACT studies
 Not all studies include values measures
 Those that do usually operationalise as
quality of life/satisfaction with life: state
not behaviour
Existing values measures
 Outside ACT
 Rokeach Values Questionnaire
 Schwartz Values Survey
 Values In Action (VIA)
 Inside ACT


VLQ
Bull’s Eye
Chronic Pain Values Inventory (CPVI)
Survey of Life Principles
Personal Values Questionnaire (PVQ)
Difficulties with individual domains
methods
 Having domains considered individually do not represent
how values work – i.e., out of context of choice, promote
intellectualised / idealised choosing; ranking would be
more realistic but creates psychometric limitations
 Therefore, empirically all domains get high importance
ratings: little differentiation (McCracken & Yang, 2006)
 Also high social desirability
 Difficult to weight/combine across domains meaningfully.
 Time is limited; valuing as a verbal-linguistic activity is relatively
unlimited. e.g.,Low consistency in one domain due to high
consistency in another domain may still reflect living relatively
ideal valued living
 One behaviour may serve more than one value; one valued
domain may be served by many behaviours
 Assessing by domain increases number of items; makes
it difficult to capture other ACT-specific qualities of values
in a brief measure
Methodology: Item generation
 Searched key ACT texts for “value” references to comprehensively
cover the concept from an ACT perspective

Methodology: Item generation
 Apparent key features of values from ACT standpoint:
 Clarity
 Priority
 Chosen; Pliance not main source of control
“Justification of actions involves fitting them into existing culturally supported verbal
networks…in many ways this is the exact opposite of valuing” (Hayes et al., 1999,
p.208)
 Enactment
“To some degree, we engage in an act of valuing each time we do something that is
purposive or instrumental” (Luoma et al., 2007, p.131)
 Persistence
“If the client bases living entirely on the absence of emotional or cognitive obstacles,
then valued directions cannot be pursued in a committed fashion (Hayes et al,
1999, p.210).
 Engagement/vitality
“living in accord with one’s values lends an inherent sense of purpose and vitality that
makes confronting monsters a legitimate and honourable undertaking” (Hayes et
al., 1999, p.209)
 Consistency/stability
“Values are more abstract and global than concrete verbal goals and thus provide a
kind of verbal glue that makes sets of verbal goals more coherent” (Hayes et al,
1999, p. 207); “Basic values seldom change” (Hayes et al., 1999, p.259)
Methodology: Item generation
 Brainstormed a list of items to tap each facet.
 Initially gave list of 64 items to friends/family to rate readability
(clear, not sure, unclear) & provide comments
 A list of the 64 items then given to one group (n=4) of ACT experts
to rate how well each item represents valuing on a scale of 0 to 4.
 Items deleted/amended on feedback, new items generated, 79item list provided to 3 other experts to rate for representativeness
(Thanks to Patty Bach, Rob Zettle, Robyn Walser, Russ Harris, Joe
Ciarrochi, Kirk Strosahl, Jennifer Plumb)
 Final list of 70 items.
 Questionnaire starts with the statement:


“1. Please read each statement carefully and then select the number
which best describes how much the statement was true for you
DURING THE PAST WEEK, INCLUDING TODAY.
Likert Scale from 0 (Not At All) to 6 (Completely)

I tried to work towards important goals, but something always got in the way
I had unpleasant thoughts and emotions that stopped me from achieving my goals
Difficult thoughts, feelings or memories got in the way of what I really wanted to do
It seemed like I was just ‘going through the motions’, rather than focusing on what
was important to me
I spent a lot of time trying to please other people
I found it hard to follow through on important activities because of unpleasant
thoughts and feelings
Most of what I did was to please other people, rather than doing what’s important to
me
I was basically on “auto-pilot” most of the time
When things didn’t go according to plan, I gave up easily
I found it hard to stay focused and engaged with what I was doing

Summary of Valuing
Questionnaire Findings
 General (rather than domain-specific) values measure
 Captures two facets of valuing (r = -.516)
 Factors are internally reliable
 Items generated in consultation with ACT experts and
literature
 Convergent Validity demonstrated with established
ACT & Non-ACT measures, although is VQ functioning
as mood measure in current form or is it that existing
ACT Values measures are problematic?
How should a valuing questionnaire
be validated? Future work
 ?Test more “behavioural” item version
 Comparing questionnaire responses to other means of capturing
valued behaviour (e.g., diaries, EMA)
 Correlation between Valuing Questionnaire responses and size of
domain-specific values-behaviour correlations
 Developing norms for clinical and high-achieving/ “successful”
populations
 Sensitivity to change: in general; to values-focused interventions
AND OF COURSE FINALISING THE STATISTICAL ANALYSES ON
THE CURRENT DATA SET
Primary outcome measures in ACT studies
17 studies: 8 measure distress/symptoms; 2 measure willingness, 4 measure
problem behaviours, 3 objective/indirect measures of problem behaviour.
0 directly measure changes in valued living.

“What percentage of the time did you feel you were spending time on the
things that are important to you?” (0-100)
 % time spent in things important: 48.31% → 71.55% over therapy
 Valued action was not a significant predictor of quality of life after
acceptance controlled

Existing values measures
 Values In Action (VIA)
 Designed to measures 24 “character strengths”
(e.g., creativity, vitality, kindness)
 Individual rates agreement with statements
describing behaviour representative of strength
(e.g., “am able to come up with new and different
ideas”) A = very much like me – E = very much
unlike me
 High item numbers (e.g., 213-item version used by
MacDonald et al, 2008)
 Trait-like in standard form: encourages personality
assessment
Existing values measures
Valued Living Questionnaire (VLQ)
(Wilson et al., 2010)
 Individual rates each of 10 valued domains 1-10 for
Importance and how consistently has lived according to how
much they value the domain:










Family relations
Marriage/couples/intimate relations
Parenting
Friendships/social
Employment
Education/training
Recreation
Spirituality
Citizenship/Community Life
Physical Well-being
Existing values measures
 Bull’s eye (Lungdren et al, 2005):
 Individual places x to represent how
consistent his/her actions are to
his/her valued direction
 Distance from bull’s eye =
discrepancy in valued living
 Final Bullseye = psychological barriers
to valued living. Individual places X
representing persistence in pursuing
values in face of barriers
 Test-retest reliability r = .86
 Mediation of follow-up changes in
seizures, personal wellbeing from
ACT for epilepsy (Lungdren et al.,
2008)
VLQ
(Wilson et al., 2010)
 Validation with n=338
undergraduates and Butcher
Treatment Planning Inventory
 Importance range limited: mean
ratings from 7.43 – 9.46
 Importance-consistency product
normally distributed
 One factor accounts for 35%
variance: item-factor loadings
ranged .39 - .65.
 Internal consistency importance
α = =.77 and consistency α =.75
: interpretation needs validation.
VLQ
(Wilson et al., 2010)
 Consistency subscale correlation with ‘% time on things that
are important to you’ = .4 (Hayes et, 2010)
 Very low correlation with AAQ r = -.14
 Correlation with MCSD r = .25
 ?VLQ ‘consistency’ wording confusing when individuals rate
domain low importance
CPVI
McCracken & Yang, 2006:
 6 domains (family, intimate relations, friends, work, health,
growth & learning)
 Rate importance 0 (not at all) - 5 (extremely important)
 Rate success 0(not at all) – 5 (extremely successful)
 Importance-success discrepancies unrelated to pain intensity
 α = .82 (success, discrepancy)
CPVI
CPVI cont..
 Discrepancy score is sensitive to
change (Johnston et al., 2010)
 Moderate relations to general
health (SF-36) .36-.53 & unique
variance after Acceptance &
mindfulness in 7/8 SF-36 scales
(McCracken & Vellerman, 2010)
 Prospectively predict pain-related
anxiety and impairment (Vowles &
McCracken, 2008)

 52 items representing 10 universal values cluster of Schwartz
 Each rated 1-9 for importance, pressure to hold & 1-5 putting into
practice & success in implementing.
 Norms for university students for Importance, Pressure, Success,
Activity for each item.
Personal Values Questionnaire
(PVQ)
(Blackledge et al)
 9 values domains (full version); 3 value domains (family, couple
relationships, friendships)
 Individual writes down their value statement in each domain and
then rates on 1-5 scale:









Importance
Commitment to living the value
Desire to improve progress
Success in living the value in last 10 weeks
Social pressure to hold value
Guilt/shame if value was not important
Importance free of social pressure
Extent the value makes life meaningful
Experience fun and enjoyment when living consistently with value
