Timeframe: Average over months 1-12

Measured using the Roland-Morris Disability Questionnaire (RMDQ), a 24-item questionnaire that measures the degree to which a low back problem restricts daily activities. Score ranges from 0 to 24 with higher values indicating more disability. Missing monthly outcomes were multiply imputed. Means were estimated using marginal standardization with adjustment for site, time period, risk of chronicity, and baseline RMDQ.

Timeframe: Weeks 1-52

Population: Only participants with at least 35 weeks of follow-up between weeks 1 and 52 are included in the analysis.

Participants report the number of days that low back pain has been a problem in the past 7 days for 52 weeks. This measure is the percent of days that low back pain has been a problem. Mean and confidence intervals are estimated using marginal standardization and bootstrapping. Adjustment for site, time period, and risk for chronicity.

Includes provider visits, emergency department visits, diagnostic imaging scans, hospitalizations, injections and surgical procedures. This is a binary indicator of any care from providers outside the study for low back pain.

Timeframe: Months 4-12

Population: Only participants with at least 6 months of follow-up between months 4 and 12 are included in the analysis.

Over the counter and prescription medication use for low back pain. Since the MC arm intervention includes medications, only months 4-12 (i.e. after the intervention) are considered for this outcome. The measure is the percent of months 4-12 in which medication was used for low back pain. Mean and confidence intervals are estimated using marginal standardization and bootstrapping. Adjustment for site, time period, and risk for chronicity.

There are some participants who completed the RMDQ but not this measure and vice versa. Thus the analysis counts for each time point here may differ somewhat from the Participant Flow tables.

Measured using a 7-point Likert scale: 0 (completely dissatisfied) to 6 (completely satisfied)

Population: The Participant Flow tables show counts of completed follow-up defined by completion of the Roland-Morris Disability Questionnaire (RMDQ). There are some participants who completed the RMDQ but not this measure and vice versa. Thus the analysis counts for each time point here may differ somewhat from the Participant Flow tables.

The PROMIS sleep disturbance scale consists of 4 questions related to sleep disturbance over the past 7 days. The raw score is converted to the T-Score that is reported here. The range of possible scores is 32.0 - 73.3. Higher scores indicate greater sleep disturbance. A score of 50 represents the average score in a general US reference population and 10 is the standard deviation.

The STarT Back Screening Tool is a 9-item questionnaire used to identify prognostic risk factors in patients with low back pain. It assesses physical and psychosocial factors, including referred pain, disability, fear-avoidance, anxiety, and depression. Scores are totaled (0-9) and a psychosocial subscale score (items 5-9, range 0-5) is calculated. Patients are classified as: low risk (total ≤3), medium risk (total ≥4 and psychosocial subscale ≤3), or high risk (total ≥4 and psychosocial subscale ≥4).
