Clinicians recognize the importance of monitoring aberrant medication-related behaviors of chronic pain patients while being prescribed opioid therapy. The purpose of this study was to develop and validate the Current Opioid Misuse Measure (COMM) for those pain patients already on long-term opioid therapy. An initial pool of 177 items was developed with input from 26 pain management and addiction specialists. Concept mapping identified six primary concepts underlying medication misuse, which were used to develop an initial item pool. Twenty-two pain and addiction specialists rated the items on importance and relevance, resulting in selection of a 40-item alpha COMM. Final item selection was based on empirical evaluation of items with patients taking opioids for chronic, noncancer pain (N=227). One-week test-retest reliability was examined with 55 participants. All participants were administered the alpha version of the COMM, the Prescription Drug Use Questionnaire (PDUQ) interview, and submitted a urine sample for toxicology screening. Physician ratings of patient aberrant behaviors were also obtained. Of the 40 items, 17 items appeared to adequately measure aberrant behavior, demonstrating excellent internal consistency and test-retest reliability. Cutoff scores were examined using ROC curve analysis and reasonable sensitivity and specificity were established. To evaluate the COMM's ability to capture change in patient status, it was tested on a subset of patients (N = 86) that were followed and reassessed three months later. The COMM was found to have promise as a brief, self-report measure of current aberrant drug-related behavior. Further cross-validation and replication of these preliminary results is pending.

The original Screener and Opioid Assessment for Patients with Pain (SOAPP) is a conceptually derived self-report questionnaire designed to predict aberrant medication-related behaviors among chronic pain patients considered for long-term opioid therapy. The purpose of this study was to develop and validate an empirically-derived version of the SOAPP (SOAPP-R) that addresses some limitations of the original SOAPP. In successive steps, items were reduced from an initial pool of 142 to a 97-item beta version. The beta version was administered to 283 chronic pain patients on long-term opioid therapy. Items were evaluated based on data collected at follow-up, including correlation with the Aberrant Drug Behavior Index (ADBI), derived from interview data, physician ratings, and urine toxicology screens. Twenty-four items were retained and comprise the final SOAPP-R. Coefficient α was .88, and receiver operating characteristics (ROC) curve analysis yielded an area under the curve (AUC) of .81 (p < .001). A cutoff score of 18 showed adequate sensitivity (.81) and specificity (.68). The obtained psychometrics, along with the use of a predictive criterion that goes beyond self-report, suggest that the SOAPP-R is an improvement over the original version in screening risk potential for aberrant medication-related behavior among persons with chronic pain. Perspective:There is need for a screener for abuse risk in patients prescribed opioids for pain. This study presents a revised version of the Screener and Opioid Assessment for Patients with Pain (SOAPP-R) that is empirically-derived with good reliability and validity, but is less susceptible to overt deception then the original SOAPP v.1.

At present, while there is insufficient empirical evidence that psychological screening before surgery or device implantation helps to improve treatment outcomes, the current literature suggests that psychological factors such as somatization, depression, anxiety, and poor coping, are important predictors of poor outcome. More research is needed to show if early identification and treatment of these factors through psychological screening will enhance treatment outcome.

Physicians can encounter problems in prescribing opioids for some patients with chronic pain such as multiple unsanctioned dose escalations, episodes of lost or stolen prescriptions, and positive urine drug screenings for illicit substances. This study explored the usefulness of questions on abuse history in predicting problems with prescribing opioids for patients at a hospital-based pain management program. One hundred forty-five (145) patients who were taking long- and short-acting opioids for their pain were classified as high or low risk on the basis of their responses to interview questions about 1) substance abuse history in their family, 2) past problems with drug or alcohol abuse, and 3) history of legal problems. The treating physicians completed a questionnaire about problems that they had encountered with their patients. Problem behaviors were verified through chart review. No differences in demographic characteristics were found between those classified as high and low risk. Patients who admitted to a family history of substance abuse, a history of legal problems, and drug or alcohol abuse were prone to more aberrant drug-related behaviors, including a higher incidence of lost or stolen prescriptions and the presence of illicit substances in their urine (P < 0.05). Patients classified as high risk also had a significantly higher frequency of reported mental health problems and motor vehicle accidents. More of these patients smoked cigarettes, tended to need a cigarette within the first hour of the day, took higher doses of opioids, and reported fewer adverse effects from the medications than did those without such a history (P < 0.05). This study demonstrates that questions about abuse history and legal problems can be useful in predicting aberrant drug-related behavior with opioid use in persons with chronic noncancer pain.

This manuscript describes the development and initial validation of a self-report questionnaire designed to assess an individual's readiness to adopt a self-management approach to their chronic pain condition. Theory and preliminary empirical work informed the development of a pool of items that were administered to a sample of individuals reporting chronic pain. Analyses of the data support a four factor measure that is consistent with the transtheoretical model of change and associated stages of change model. Each of the four factors, precontemplation, contemplation, action, and maintenance, was found to be internally consistent and stable over time. There was also substantial support for each factor's discriminant and criterion-related validity.

There has been a need for a brief assessment tool for providers who treat chronic pain patients to determine potential risk of abuse when prescribed opioids for pain. The purpose of this study was to develop and begin the validation of a self-administered screening tool (Screener and Opioid Assessment for Patients with Pain, SOAPP) for chronic pain patients considered for long-term opioid therapy. A consensus of 26 pain and addiction experts was obtained on important characteristics of chronic pain patients that predict future medication misuse using concept mapping. A 24-item SOAPP (version 1.0) was developed based on this consensus and was administered to 175 patients who were taking opioids for chronic pain. After 6 months, 95 of these patients were re-evaluated. Validation of the SOAPP was conducted by identifying those patients exhibiting aberrant drug-related behavior as determined by any of the following: a positive score on the Prescription Drug Use Questionnaire (PDUQ) interview, positive urine toxicology screen, and/or ratings by staff as to whether patients had a serious drug problem. Of the original 24 items, 14 SOAPP items appeared to predict subsequent aberrant behaviors. Coefficient alpha for these 14 items was acceptable for a short scale (0.74). Receiver operating characteristics curve analysis yielded an area under the curve of 0.881 (P<0.001), suggesting adequate sensitivity and specificity for a screening device. These reliability and predictive validity results suggest that the SOAPP is a promising step toward screening risk potential for substance misuse among persons with chronic pain.

Chronic pain patients who have limited access to opioids may be redirected to methadone maintenance centers for management of their pain. Unfortunately, little information exists on the incidence and characteristics of methadone maintenance patients with chronic pain. The aim of this study was to survey individuals at methadone maintenance centers in order to determine the prevalence of chronic pain and to explore differences between patients with and without pain in this treatment setting. Of 248 participants interviewed at three centers, 152 (61.3%) reported chronic pain. Compared with patients without pain, those with pain reported significantly more health problems (P < 0.001), more psychiatric disturbance (P < 0.05), more prescription and nonprescription medication use (P < 0.001), and greater belief that they were undertreated (P < 0.001); 44% of those with pain believed that opioids prescribed for their pain had led to an addiction problem. Most of the methadone maintenance patients stated that they had always required some substance (alcohol or opioids) to feel normal. These results raise many questions about chronic-pain treatment policies and resources for persons with a history of substance abuse. Further investigations are needed to define the needs of this population and to improve their access to effective pain management.

Chronic pain patients who show aberrant drug-related behavior often are discontinued from treatment when they are noncompliant with their use of opioids for pain. The purpose of this study was to conduct a randomized trial in patients prescribed opioids for noncancer back pain who showed risk potential for or demonstration of opioid misuse to see if close monitoring and cognitive behavioral substance misuse counseling could increase overall compliance with opioids. Forty two patients meeting criteria for high risk for opioid misuse were randomized to either standard control (High-Risk Control; N=21) or experimental compliance treatment consisting of monthly urine screens, compliance checklists, and individual and group motivational counseling (High-Risk Experimental; N=21). Twenty patients who met criteria indicating low potential for misuse were recruited to a low-risk control group (Low-Risk Control). Patients were followed for 6 months and completed pre- and post-study questionnaires and monthly electronic diaries. Outcomes consisted of the percent with a positive Drug Misuse Index (DMI), which was a composite score of self-reported drug misuse (Prescription Drug Use Questionnaire), physician-reported abuse behavior (Addiction Behavior Checklist), and abnormal urine toxicology results. Significant differences were found between groups with 73.7 % of the High-Risk Control patients demonstrating positive scores on the DMI compared with 26.3% from the High-Risk Experimental group and 25.0% from the Low-Risk Controls (p<0.05). The results of this study demonstrate support for the benefits of a brief behavioral intervention in the management of opioid compliance among chronic back pain patient at high-risk for prescription opioid misuse.
