TL;DR: Paroxetine appears to have a “true” pharmacological effect on the psychological but not on the somatic symptoms of depression and anxiety, which appears to be mostly duplicated by placebo.

TL;DR: The authors did not find any significant recall period effect on PF8c responses, and recommend the use of the PROMIS physical function standard, with no specified recall time period.

TL;DR: The authors fit a nominal response item response theory model to responses to the Health Care Engagement Measure (HEM) and found that higher response category distinctions, such as responding 3 (very true) versus 2 (mostly true) were considerably more discriminating than lower response categories distinctions.

TL;DR: In this paper, the authors conducted cognitive interviews followed by a nation-wide mail survey of US Veteran Administration (VA) healthcare users, where data were collected on 49 candidate healthcare engagement items, as well as measures of self-efficacy for managing symptoms, provider communication, and perceived access Items were subjected to exploratory bifactor, statistical learning, and IRT analyses Cognitive interviews were completed by 56 patients and 9552 VA healthcare users with chronic conditions completed the mail survey Participants were mostly white and male but with sizable minority participation.
