Opioids are frequently prescribed for chronic low back pain (CLBP). Psychiatric illness, such as high levels of depression and anxiety symptoms, is a common co-occurrence in chronic pain patients (and is termed comorbid negative affect [NA]). The purpose of the study is to determine whether CLBP patients with either a high vs. a low or moderate degree of NA have different pain relief responses to oral opioids.
The level of high, moderate or low NA was determined based on the participant's score on the Hospital Anxiety and Depression Scale (HADS). The HADS is a self-reported questionnaire that has 14 questions related to 2 domains: Anxiety subscale (7 questions) and Depression subscale (7 questions). Each item on the questionnaire is scored from 0 (least amount of anxiety/depression) to 3 (greatest amount of anxiety/depression), with total score between 0 and 21 for either anxiety or depression. Participants were assigned to high, moderate or low NA groups using the following HADS score criteria:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Low Negative Affect (NA) | Active Comparator | Participants with low NA (HADS score ≤5 on each subscale) received placebo or active opioid drug (immediate-release morphine 15 to 30 mg or oxycodone 5 to 10 mg) up to three times a day as needed for 1 week each in random order, followed by morphine or oxycodone titrated to a maximum allowable daily dose in morphine equivalents of 30 mg for short-acting medication and 60 mg for long-acting medication, respectively, three times a day for up to 20 weeks, followed by morphine or oxycodone tapering (individualized opioid dose was decreased by approximately 25% each week) for 4 weeks. |
|
| Moderate NA | Active Comparator | Participants with moderate NA (HADS score ≥6 to ≤8 on each subscale) received placebo or active opioid drug (immediate-release morphine 15 to 30 mg or oxycodone 5 to 10 mg) up to three times a day as needed for 1 week each in random order, followed by morphine or oxycodone titrated to a maximum allowable daily dose in morphine equivalents of 30 mg for short-acting medication and 60 mg for long-acting medication, respectively, three times a day for up to 20 weeks, followed by morphine or oxycodone tapering (individualized opioid dose was decreased by approximately 25% each week) for 4 weeks. |
|
| High NA | Active Comparator | Participants with high NA (HADS score ≥9 on each subscale) received placebo or active opioid drug (immediate-release morphine 15 to 30 mg or oxycodone 5 to 10 mg) up to three times a day as needed for 1 week each in random order, followed by morphine or oxycodone titrated to a maximum allowable daily dose in morphine equivalents of 30 mg for short-acting medication and 60 mg for long-acting medication, respectively, three times a day for up to 20 weeks, followed by morphine or oxycodone tapering (individualized opioid dose was decreased by approximately 25% each week) for 4 weeks. |

| Percent Change in Average Daily Pain Score | Participants rated their average lower back pain over the past 24 hours using an 11-point scale (0=no pain to 10=worst possible pain) and recorded it in an electronic diary. The percent change in pain score from baseline is calculated using weekly averages for up to 20 weeks. Linear mixed modeling (LMM) analysis was used to allow for inclusion in the analysis of the majority of participants with any missing data. For the LMM model, group, group × week, average baseline pain, and opioid use at baseline (yes/no) were entered as fixed effects using an autoregressive covariance structure. Participant, intercept, and week were entered as random effects, using a compound symmetry covariance structure. A positive change from baseline indicates an improvement. | Baseline and Week 20 |

NA level determined by Hospital Anxiety and Depression Scale (HADS) score: Anxiety and Depression subscales with 7 questions each, each question scored 0 (least) to 3 (greatest) amount of anxiety/depression, total score 0-21. High NA=score ≥9 on each subscale, Moderate NA=score ≥6 to ≤8 on each subscale, Low NA=HADS score ≤5 on each subscale.
Volunteers with chronic low back pain (CLBP) and psychiatric illness (comorbid negative affect [NA]) were recruited to participate in this trial.
