Improved adjusted minimal important change took reliability of transition ratings into account

Objectives: The anchor-based minimal important change (MIC), based on the receiver operating characteristic (ROC) analysis or predictive modeling, is biased by the proportion of improved patients. The adjusted MIC, published in 2017, adjusts the predictive MIC for this bias but does not take the reliability of the transition ratings (i.e., the...

Minimal Clinically Important Difference Estimates Are Biased by Adjusting for Baseline Severity, Not by Regression to the Mean

Minimal clinically important difference (MCID) estimates are often used to interpret change scores from measurement instruments. Researchers debate how MCID values should be estimated. In a recent paper, Tenan et al1 recommended adjusting for baseline severity in the analysis to avoid biased MCID estimates due to regression to the mean (RTM)....

The anchor-based minimal important change, based on receiver operating characteristic analysis or predictive modeling, may need to be adjusted for the proportion of improved patients

Objectives. Patients have their individual minimal important changes (iMICs) as their personal benchmarks to determine whether a perceived health-related quality of life (HRQOL) change constitutes a (minimally) important change for them. We denote the mean iMIC in a group of patients as the “genuine MIC” (gMIC). The aims of this paper are to...

Measurement error of waist circumference: Gaps in knowledge

Objective It is not clear whether measuring waist circumference in clinical practice is problematic because the measurement error is unclear, as well as what constitutes a clinically relevant change. The present study aimed to summarize what is known from state-of-the-art research. Design To identify the magnitude of the measurement error of...

Work-related physical and psychosocial risk factors for sick leave in patients with neck or upper extremity complaints

Objectives: To study work-related physical and psychosocial risk factors for sick leave among patients who have visited their general practitioner for neck or upper extremity complaints. Methods: Three hundred and forty two patients with neck or upper extremity complaints completed self-report questionnaires at baseline and after 3 months. Cox...
