A recent study has revealed that reductions in pain intensity may not be the earliest signs of improvement chronic pain patients show in response to effective pain management.

Researchers said that, “This study demonstrates that
pain intensity scores are not robust predictors of psychosocial outcomes
longitudinally. Instead, other factors such as sleep initiation, psychological
distress, and disability appear to be important targets for intervention that
may promote effective pain reduction.”
Utilizing retrospectively collected data from 666 treatment-seeking
patients with an average age of 49.6 years where 67.9% are women with chronic
pain, cross-lagged models were constructed to assess the correlation between
average pain intensity and disability, sleep initiation and maintenance, and
psychological distress. The analysis was performed over a 1-year time frame.
The models revealed that greater pain-related interference
with sleep maintenance, but not sleep initiation, was significantly predictive
of higher pain intensity at the following time point.
Additionally, more severe baseline symptoms of
depression, as well as anxiety and disability significantly associated with
worse pain intensity at the next time point.
On the other hand, pain intensity had no such lagged
effect on depression, anxiety, or disability.
Results point to a complex temporal relationship among
pain intensity and other clinical indicators of chronic pain. Specifically,
while pain intensity revealed an initial lagged effect on sleep at a follow-up time
point, the lack of similar effect on other significant variables suggest that
intensity need not be the central measure of improvement following treatment.
Researchers said, “Our results highlight the need for
multifactorial assessment and treatment of individuals with chronic pain and,
further, suggest that in may not be necessary to reduce pain intensity before
improvements in sleep, mood, and function can occur.”
