The Current Opioid Misuse Measure (COMM) is a self-report measure of risk for aberrant medication-related behavior among persons with chronic pain who are prescribed opioids for pain. It was developed to complement predictive screeners of opioid misuse potential and improve a clinician's ability to periodically assess a patient's risk for opioid misuse. The aim of this study was to cross-validate the COMM with a sample of chronic noncancer pain patients. ⋯ Results of the cross validation suggest that the psychometric parameters of the COMM are not based solely on unique characteristics of the initial validation sample. The COMM seems to be a reliable and valid screening tool to help detect current aberrant drug-related behavior among chronic pain patients.

Comparative Study
Comparing the STarT back screening tool's subgroup allocation of individual patients with that of independent clinical experts.
The STarT Back Screening Tool (SBST) is validated to subgroup primary care patients with back pain into risk groups relevant to initial decision-making. However, it remains unclear how the tool's allocation of individuals compares with subjective clinical decision-making. We evaluated agreement between clinicians and the SBST's allocation to risk subgroups, and explored reasons for differences observed. ⋯ Clinicians make inconsistent risk estimations for primary care patients with back pain when using intuition alone, with little agreement with a formal subgrouping tool. Unlike clinicians, the SBST could not make a sophisticated synthesis of patient preferences, expectations, and previous treatment history. Although acknowledging the limitations of back pain subgrouping tools, more research is needed to test whether their use improves consistency in primary care decision-making.

Systems controlling cardiovascular function are closely coupled with the perception of pain. Heart rate variability (HRV) is a well-established noninvasive measure of cardiac autonomic control. We hypothesized that pain may alter HRV in the newborn infant and that HRV analysis could be used as an indicator of prolonged pain in the newborn infant. ⋯ The results of this study indicate that postoperative pain is associated with a decreased high-frequency HRV in full-term newborn infants. Our findings suggest that HRV could be used as an indicator to assess prolonged pain in the newborn infants.

Catastrophic appraisal has been implicated as a possible cause of psychiatric morbidity, psychological distress, and physical impairment in individuals with chronic pain. At issue in this study was whether catastrophizing was associated with psychiatric morbidity in a population sample of National Guard members. In addition, we sought to determine whether it could account for individual differences in psychological distress and impaired physical function in the presence of acute and chronic pain. ⋯ Although catastrophizing beliefs are common in clinical settings, this study suggests that the phenomenon may be prevalent in the population at large and likely to influence the outcome of acute as well as chronic pain.
