Arm && Interventions

Group	Intervention	Description
Cognitive behavioral therapy	Cognitive behavioral therapy	Cognitive behavioral therapy aimed at reducing pain catastrophizing.

Primary Outcome Measures

Name	Time	Method
Feasibility (as determined by attrition rate)	After each cohort completes their 5 group CBT sessions; 1 week after the 5th and final CBT session in each cohort
Change in menstrual pain level assessed via 11-point numeric rating scale (NRS)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
Change in medication use (dosage and frequency of pain medication use)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
Acceptability - participants' views of the intervention's 1) appeal; 2) helpfulness; and 3) ease of participation	Assessed via qualitative interviews which will occur during each participant's post-intervention lab assessment (i.e., during the first two days of the first menstrual period after intervention completion)
Change in pain catastrophizing	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion

Secondary Outcome Measures

Name	Time	Method
Change in menstrual symptoms as assessed by the Menstrual Symptom Questionnaire (MSQ)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
Change in anxiety as assessed by the Brief Symptom Inventory 18 (BSI-18)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
Change in depression as assessed by the Brief Symptom Inventory 18 (BSI-18)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
Change in temporal summation (TS)	Assessed at pre- and post-intervention lab sessions, each of which will occur during the first 2 days of menstruation
Change in conditioned pain modulation (CPM): pain ratings in response to a heat stimulus prior to and after administration of a conditioning pain stimulus (cold water)	Assessed at pre- and post-intervention lab sessions, each of which will occur during the first 2 days of menstruation
Change in somatization as assessed by the Brief Symptom Inventory 18 (BSI-18)	Assessed via questionnaire completed at six time points: pre-intervention lab session, immediately following the completion of the 5th group CBT session, post-intervention lab session, and once a month for three months after intervention completion
