Living Successfully with Chronic Living Successfully with Chronic Pain: Pain:
• A cross sectional study of chronic pain patients
• Results
• Discussion
BackgroundBackground• Chronic pain is pain that persists beyond 6
months or continues after the normal time of healing
• Complex multifactorial causes, both physiological and psychological
• Survey of 46,394 people in 15 European countries19% of adults of working age had moderate to severe chronic pain
(Brevik et al, 2006)
BackgroundBackground
• Theories suggesting psychogenic causation have not been supported by empirical evidence
• Behavioural and Cognitive understandings have fit the data better, have been influential in understanding pain and helpful to clinicians in treating pain
(Sullivan et al, 1995; Keefe, Brown, Wallston et al., 1989; Turner, Mancl & Aaron, 2004; Ellis & D’Eon, 2002; however Dixon et al, 2004 found less stable)
• Strong relationships between catastrophising and most indices of functioning:Pain intensity, disabilty and distress (Severeijins et al., 2001)
Quality of life (Lame et al., 2005)
Depression (Geisser et al, 1994; Jensen et al, 1991; Turner et al, 2000)
Observable pain behaviour & spousal responses(Sullivan et al, 2004; Boothby et al, 2004; Keefe et al, 2000)
Coping FrameworkCoping Framework• Strong evidence that coping behaviour is related to
pain intensity, emotional and physical functioning(Keefe et al, 1997; 2004; Jensen et al, 1991; Haythornthwaite et al, 1998)
• Coping means behaving in certain ways and thinking in certain ways in an effort to minimise pain, minimise distress and maintain function
• Variability in types of coping and their effectiveness(Haythorthwaite et al, 1998)
AcceptanceAcceptance• Coping frameworks offer an incomplete model
• Efforts at minimising pain and emotion may paradoxically reduce function
(McCracken, 1988; McCracken et al, 2004; McCracken and Eccleston, 2003; 2006; McCracken and Samuel, 2006)
• Pain control / coping can be viewed as a form of avoidance behaviour
• Avoidance of stimuli enhances their aversive properties(McCracken 1998)
AcceptanceAcceptance• Acceptance based treatment aims to reduce
efforts to control or minimise pain & distress
• Mindfulness and willingness experiential techniques are used to promote willingness to have pain
• In order that people make direct contact with values and value linked goals that give life meaning and purpose
AcceptanceAcceptance• Defusion techniques are used to de-literalise and
decenter from distress and thoughts that are associated with distress, in an effort to change the function of these experiences in cueing avoidant behaviour
• Preliminary evidence suggests ACT based treatments for pain are effective
(McCRacken et al., 2005; Vowles & McCracken, 2008; Dahl, Wilson & Nilsson, 2004; Wicksell, Dahl, Magnusson & Olsson, 2005)
AcceptanceAcceptance• Many cross sectional, prospective, experimental
and mediational studies support the finding that acceptance based approaches and understandings provide a fuller understanding of adjustment in chronic pain
(Wicksell et al., 2008; McCracken, Vowles & Gauntlet-Gilbert, 2007; McCracken and Vowles, 2007; 2008; McCracken, Gauntlett-Gilbert & Vowles, 2007; Vowles,
McCracken and Eccleston, 2007; Paez-Blarina, Luciano et al., 2008; McMullen, Barnes-Holmes et al., 2008; McCracken & Yang, 2006; Hates et al, 1999; Masedo &
Esteve; 2007; Gutierrez, Luciano et al., 2004)
SummarySummary• Pain patients’ behavioural functioning is
compromised
• Pain patients’ emotional functioning is also affected
• Beliefs & appraisals are strongly associated with behavioural and emotional functioning
• Acceptance also appears to play an important role in emotional and behavioural functioning.
Research QuestionsResearch Questions
• How are these constructs related?
• Which predicts emotional and behavioural functioning better: appraisals or acceptance?
• Are certain appraisals associated with catastrophising and acceptance?
MethodMethod• Cross sectional study
• Standardised Questionnaire measurement
• Clinical sample of heterogenous chronic pain patients
• Recruited from Pain clinics in Tayside and Lothian
MeasuresMeasures• Demographics: age, gender, duration of pain…
• Chronic Pain Acceptance Questionnaire (CPAQ: McCracken et al., 2004)
“I’m getting on with the business of living no matter what my pain is”“Controlling pain is less important than other goals in my life”
• Pain Catastrophising Scale(PCS: Sullivan et al., 1995)
“I worry all the time whether the pain will end”“There’s nothing I can do to reduce the intensity of the pain”
“My pain is a mystery to me”“My pain has serious financial consequences”
• McGill Pain Questionnaire – Short Form(MPQ-SF: Melzack, 1987)
• Hospital Anxiety & Depression Scale(HADS: Zigmond and Snaith, 1983)
MeasuresMeasures• Roland & Morris Sickness Impact Profile
(R&MSip: Roland & Morris, 1983)
“I have to lie down and rest more”“I try to get other people to do things for me”“I only walk short distances”“I avoid heavy jobs around the house because of pain”“I try not to kneel or bend”
AnalysisAnalysis
• Path analytic modelling was used(Bramwell, 1996)
• Power analysis indicated a sample size of 109 participants would be needed to detect a medium effect size at alpha 0.05 and power 0.80
(Green, 1991; Cohen, 1992)
