iPAWS: Improving Pain Management After Wisdom Tooth Extraction Surgery

The number of participants who complete the active treatment phase will determine feasibility. The treatment will be considered feasible if the number of participants who complete treatment is ≥ 70%.

The Client Satisfaction Questionnaire (CSQ-8) which ranges in scores from 8 to 32 will determine acceptability. Higher scores indicate higher satisfaction (i.e. better outcomes). Treatment will be considered acceptable if the number and percentage of participants who rate their experience either "satisfactory" or "highly satisfactory is ≥ 80%.

Number of days that participants consumed cannabis over the last 3 weeks (weeks 4-6 of treatment) will be measured by the Timeline Followback Interview.

Average pain intensity is assessed during daily Ecological Momentary Assessments using the Numerical Rating Scale (NRS) .

This is assessed on a scale from 0 (no pain) to 10 (most pain possible). Minimum value= 0 and maximum value=10. Higher scores indicate higher levels of pain (i.e. worse outcome).

Analysis will examine average pain levels after treatment (weeks 4-6).

Substance use craving is measured during daily Ecological Momentary Assessments using an item validated in past work: "How strong is your urge to use substances right now? This includes marijuana, alcohol, nicotine, and other drugs."

This is assessed on scale from 0 (no urge) to 10 (strongest urge ever). Minimum value= 0 and maximum value=10 and higher scores indicate higher levels of craving (i.e. worse outcomes).

Analysis will examine responses to this item after treatment (weeks 4-6).

Abstinent days (proportion of days on which no cannabis use is reported) during the last 3 weeks (treatment weeks 4-6). The analysis will control for baseline (defined as proportion of abstinent days in the two weeks preceding the treatment).

Pain interference is assessed during daily Ecological Momentary Assessments using 1 item: "How much is physical pain getting in the way of doing regular daily activities right now, including eating and drinking?" This is assessed on a scale from 0 (not at all ) to 10 (extremely). Minimum value= 0 and maximum value=10. Higher scores indicate higher levels of pain interference (i.e. worse outcome). Analysis will examine ratings of pain interference after treatment (weeks 4-6).

Utilization of non-pharmacological pain coping skills is assessed during daily Ecological Momentary Assessments using a checklist of psychosocial (n=10 items) and physical coping strategies (n=10 items). Responses are binary (yes or no). The minimum value for each type of skill is 0 and the maximum value is 10. Higher scores reflect higher utilization of these skills (i.e. better outcomes). Analysis will examine utilization of non-pharmacological pain coping skills after treatment (weeks 4-6)
