Pain-related pictures are useful for studying how individuals respond to pain-related stimulation. Such pictures can occasionally be found in databases for affective pictures. However, a validated database specifically for pain-related pictures is not available yet. ⋯ PERSPECTIVE: This article presents the validation of the experimental pain pictures system, which consists of a set of pain-related pictures. The experimental pain pictures system is composed of pictures depicting different types of pain. Participants rated all the pictures as being negative, arousing, and painful.

Review Meta Analysis
Efficacy and safety of transdermal buprenorphine for acute postoperative pain: A systematic review and meta-analysis.
Transdermal buprenorphine (TBUP) may have some advantages for the management of acute postoperative pain. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of TBUP compared to other analgesics or placebo for acute postoperative pain. A systematic search was conducted using Embase, MEDLINE, and Cochrane Central Register of Controlled Trials (CENTRAL) until December 26, 2022. ⋯ PERSPECTIVE: This systematic review and meta-analysis compared the use of TBUP to other analgesics for postoperative pain. The results showed that there is insufficient evidence to recommend the use of TBUP in this setting. The findings will help clinicians select the most appropriate opioid regimens for postoperative pain.

Numerous studies have found that pain management programs are an effective treatment option for people with chronic pain. However, little is known about when people experience improvements during these programs and why they are effective. Using a secondary analysis, the current study examined the timing and magnitude of symptom change during an 8-week internet-delivered psychological pain management program for people with chronic pain. ⋯ This study highlights the importance of the first few weeks of psychological pain management programs and encourages future work to examine how the mechanisms underpinning rapid change may be harnessed to optimize care for people with chronic pain. PERSPECTIVE: This study found that depression, anxiety, and disability improved rapidly during the first half of an 8-week internet-delivered pain management program, and most of the prepost change had occurred by midtreatment. This work highlights the therapeutic potential of the first few treatment sessions and prompts future research into a rapid responding.

This study sought to evaluate the psychometric properties of a Spanish version of the PEG scale (PEG-S, whose items assess Pain intensity and pain interference with Enjoyment of life and General activity) in a sample of Spanish-speaking adults receiving care for pain at primary care clinics in the Northwestern United States. We evaluated the PEG-S's 1) internal consistency, 2) convergent validity, and 3) discriminant validity. All participants (n = 200, mean age = 52 years [SD = 15], 76% women, mean PEG-S score = 5.7 [SD = 2.5]) identified as having Hispanic or Latino ethnicity, and detailed ethnic origin was predominantly Mexican or Chicano (70%). ⋯ The findings support reliability and validity of the PEG-S for assessing a composite score of pain intensity and interference among Spanish-speaking adults. PERSPECTIVE: We present evidence supporting the reliability and validity of the PEG scale in Spanish (PEG-S) in a sample of adults receiving pain care at primary care clinics in the Northwestern United States. This 3-item composite measure of pain intensity and interference can help clinicians and researchers assess pain among Spanish-speaking adults.

Randomized Controlled Trial
Who Benefits the Most From Different Psychological Chronic Pain Treatments? An Exploratory Analysis of Treatment Moderators.
Different psychological chronic pain treatments benefit some individuals more than others. Understanding the factors that are associated with treatment response-especially when those factors differ between treatments-may inform more effective patient-treatment matching. This study aimed to identify variables that moderate treatment response to 4 psychological pain interventions in a sample of adults with low back pain or chronic pain associated with multiple sclerosis, spinal cord injury, acquired amputation, or muscular dystrophy (N = 173). ⋯ If additional research replicates the findings, it may be possible to better match patients to their more individually suitable treatment, ultimately improving pain treatment outcomes. PERSPECTIVE: Pre-treatment measures of hypnotizability and EEG-assessed brain activity predicted who was more (or less) likely to respond to different psychological pain treatments. If these findings are replicated in future studies, they could inform the development of patient-treatment matching algorithms.
