meaning of “pain” through
experiences usually related
to injuries in early life
Dimensions of Chronic Pain
Loneliness

Anxiety
Depression
Psychological Factors
Pathological Process
Physical Factors

Is pain a learned behavior?
• William Fordyce - Operant conditioning model
• Pain behaviour is rewarded by
– solicitous attention
– not having to work
– access to drugs
• To treat need to: ignore pain behavior, reward
non-pain behavior (e.g. physical activity)

Cultural and spiritual factors

Pre-dispositional
Factors
Social factors
Pain perceptions
Behavioral factors

Fear Avoidance Model
Fear of Pain and Re-injury
• Fear of pain, movement, or re-injury thought to lead
to avoidance behaviors and hyper-vigilance to pain
Disability
Social & Environmental Factors
• Environmental responses to pain behaviors
can inadvertently reinforce pain & disability.
• There are several examples of reinforcements:

• “The awareness that emerges through paying

and non-judgmentally to the unfolding of
experience moment to moment.”
• Kabat-Zinn, 2003.
The clinical use of mindfulness meditation for the selfregulation of chronic pain.
Kabat-Zinn J, Lipworth L, Burney R.
Ninety chronic pain patients were trained in mindfulness meditation in a 10week Stress Reduction and Relaxation Program. Statistically significant
reductions were observed in measures of present-moment pain, negative
body image, inhibition of activity by pain, symptoms, mood disturbance,
and psychological symptomatology, including anxiety and depression. Painrelated drug utilization decreased and activity levels and feelings of selfesteem increased. Improvement appeared to be independent of gender,
source of referral, and type of pain. A comparison group of pain patients did
not show significant improvement on these measures after traditional
treatment protocols. At follow-up, the improvements observed during the
meditation training were maintained up to 15 months post-meditation
training for all measures except present-moment pain. The majority of
subjects reported continued high compliance with the meditation practice as
part of their daily lives. The relationship of mindfulness meditation to other
psychological methods for chronic pain control is discussed.

Being Mindful - Jon Kabat-Zinn
• Mindfulness creates space around our pain,
allowing us to work with it without being
overwhelmed.
Mindfully Working with Pain
3 Basic Strategies for Working with Pain:
1. focusing on the pain
2. focusing on the mental and emotional reactions to
the pain
3. focusing away from the pain onto something
soothing and pleasant
Mindfully Working with Pain

 Free-Floating with the Discomfort
 Breath Pleasure
 Relaxing with Out Breath
 Pleasure of O2 Entering the Body

CBT – Chronic Pain Management
• Teach Activity-Rest
Cycling (Pacing)

activity causes pain
• Pain and suffering
increase over time
• Activity decreases over
time
CBT – Chronic Pain Management
• Time-Contingent Medication Use
• Relapse Prevention
• Acceptance (e.g., Mindfulness Meditation)
• Couples/Family Communication Therapy
• Treat Co-morbid Conditions
Motivate Self management

Defuse Myths about Chronic Pain
Avoid “Psychologizing” the Problem
“Listen” and Avoid Power Struggles
Communicate Understanding in the Reality of
Pain Experience
Motivating Self management
• Introduce a Model (eg., Gate Control)
• Encourage Realistic Expectations
– (eg., 50% pain reduction, improved daily function,
etc.)
• Get a Commitment from the Patient
• Collaborate With the Patient Against “it”
Avoid these messages to the client
• Let pain be your guide
• The pain is being caused by psychological
factors
• The pain is not real – there is no reason for
your pain
Messages to Give Clients
• Pain can cause suffering
• Can’t always change pain, but you can reduce
suffering
• Reducing suffering and pain behavior can lead
to reduced pain
“Pain may be inevitable but misery is optional”
