Measurement of contextual factors in clinical practice and research: development of an expert-informed toolkit

Contextual factors (CFs) can influence therapeutic encounters and clinical outcomes, yet their measurement remains fragmented, lacking a unified framework to guide tool selection. To identify, appraise, and synthesize CF measurement instruments into an expert-informed clinical toolkit and identify current measurement gaps. An international panel of 15 experts evaluated 227 instruments across five domains (patient/practitioner characteristics, relational dynamics, environment, and treatment) using a hybrid COSMIN-informed appraisal design. Instruments were screened for content validity and psychometric robustness. Twenty instruments were selected for inclusion in the toolkit. Despite identifying high-quality instruments for stable traits, our analysis revealed critical measurement gaps in dynamic, state-responsive processes. Specifically, there is an absence of validated, clinically feasible tools for capturing real-time clinician affective states, non-verbal synchrony, therapeutic touch, and moment-to-moment environmental or procedural interactions. This study provides the first expert-informed framework for assessing CFs. Future research should prioritize developing state-responsive instruments capable of capturing these dynamic elements as they unfold in real-world settings to better understand the contextual drivers of recovery.
