What Can We Learn From More Than 140,000 Moments of Ecological Momentary Assessment-Assessed Negative Emotion and Ambulatory Blood Pressure? A Systematic Review and Meta-Analysis.

Objective: Two decades of research has examined within-person associations between negative emotion states and ambulatory blood pressure (ABP) using ecological momentary assessment (EMA), but no meta-analysis has been conducted. We conducted this systematic review and meta-analysis to quantify the magnitude of this association and identify moderators, review strengths and weaknesses in conceptual and measurement approaches, and provide recommendations.

Methods: We searched databases (PsycINFO, PubMed), identified 15 studies, and obtained data from 13 studies (n = 2511; 142,307 observations).
