Pain management programs are effective for people with chronic pain. This study found that depression, anxiety, and disability improved rapidly during the first half of an 8-week internet-delivered pain management program, while reductions in pain intensity occurred mainly during the second half of treatment.
Numerous studies have found that pain management programs are an effective treatment option for people with chronic pain. However, little is known about when people experience improvements during these programs and why they are effective. Using a secondary analysis, the current study examined the timing and magnitude of symptom change during an 8-week internet-delivered psychological pain management program for people with chronic pain. The change in 4 outcomes was examined: depression (n = 881), anxiety (n = 561), disability (n = 484), and pain intensity (n = 484). The largest improvements in depression, anxiety, and disability were reported during the first half of treatment (ie, 4 weeks), whereas the largest reductions in pain intensity were reported during the second half of treatment. Half the participants had experienced a clinically meaningful improvement in depression or anxiety, and a third of participants had reported such an improvement in disability by midtreatment (ie, 5 weeks after baseline). In a subgroup analysis (n = 397), this pattern of change in depression and anxiety symptoms did not differ based on the level of therapist guidance. This study highlights the importance of the first few weeks of psychological pain management programs and encourages future work to examine how the mechanisms underpinning rapid change may be harnessed to optimize care for people with chronic pain. Perspective: This study found that depression, anxiety, and disability improved rapidly during the first half of an 8-week internet-delivered pain management program, and most of the prepost change had occurred by midtreatment. This work highlights the therapeutic potential of the first few treatment sessions and prompts future research into a rapid responding.
