Primary care providers' use of and attitudes towards placebos: An exploratory focus group study with US physicians.
To examine how primary care physicians define placebo concepts, use placebos in clinical practice, and view open-label placebos (OLPs). ⋯ A number of physicians reported prescribing impure placebos in clinical care. Although some primary care physicians were resistant to the possibility of recommending OLPs, others regarded OLPs more favourably, viewing them as potential treatments, albeit with restricted potential. Statement of contribution What is already known? Many physicians report prescribing drugs for the purposes of eliciting a placebo effect. Initial evidence for the efficacy of open-label placebos is promising. What does this study add? A more nuanced description of the circumstances under which primary care physicians report placebo prescribing. A qualitative account of physician attitudes about using open-label placebos in clinical practice.

Development and validation of a 6-item Revised UCLA Loneliness Scale (RULS-6) using Rasch analysis.
The UCLA Loneliness Scale, containing 20 items, is one of the commonly used loneliness scales. Some shorter versions have been developed using factor analysis. The study aimed to shorten the UCLA Loneliness Scale using Rasch and factor analysis methods and test the psychometric properties of the new scale. ⋯ Using Rasch analysis, the proposed RULS-6 constituted a 70% reduction of the number of original items, yet preserved the psychometric properties in independent samples of students and psychiatric outpatients. Statement of contribution What is already known on this subject? The UCLA Loneliness Scale is a common instrument used to gauge loneliness levels. The 20-item revised scale (R-ULS) has acceptable psychometric properties but its construct varies. Due to the length of the questionnaire, administration of R-ULS is not always practical. Short versions vary in items and were developed with classic test theory (e.g., factor analysis). Rasch analysis - providing more accuracy based on measurement theory - could be used instead. What does this study add? Using a Rasch analysis approach, a 6-item scale of loneliness (RULS-6) was created. The RULS-6 was tested in student and clinical samples, meeting Rasch measurement model criteria. The RULS-6 showed promising psychometrics to be used in both non-clinical and clinical samples.

Child catastrophizing about parent chronic pain: A potential child vulnerability factor.
Objective Robust evidence suggests children's catastrophizing about their own pain is a risk factor for poor child pain-related outcomes. In children of parents with chronic pain, child catastrophizing about their parents' pain might be a unique predictor of child pain-related outcomes given their increased exposure to parental chronic pain and disability. The objective of this study was to examine associations between child and parent catastrophizing about their own and each other's pain and child and parent pain-related outcomes. ⋯ Child catastrophizing about parent chronic pain and its association with child outcomes has not been examined. What does this study add? Greater child catastrophizing about parent chronic pain is associated with greater child internalizing and CPT pain. These effects were seen beyond the association of child and parent catastrophizing about their own pain.

'It's like being conscripted, one volunteer is better than 10 pressed men': A qualitative study into the views of people who plan to opt-out of organ donation.
Objectives To overcome the shortage of organ donors, Scotland and England are introducing an opt-out organ donor registration system in 2020. This means individuals will be automatically considered to consent for donation unless they actively opt-out of the register. Research has found that emotional barriers play a key role in donor decisions under opt-in legislation, yet little is known about factors that influence donor decisions under opt-out consent. ⋯ What does this study add? This study explored why people plan to opt-out of the new system in Scotland and England. Medical mistrust and bodily integrity concerns remain as salient barriers under opt-out laws. Fears of unwarranted government control and a perceived threat to one's freedom of choice emerged as a novel barrier.
