Systematic review investigating the mental health trajectories associated with the COVID-19 pandemic

The dataset comprises datasets related to two coordinated systematic reviews on COVID-19 and mental health. Both were parts of a set of systematic reviews that prospectively registered in PROSPERO (CRD42020179703), with a protocol posted prior to initiation (https://osf.io/96csg/).

Together, the datasets capture both pre–post pandemic comparisons and prospective longitudinal assessments, providing a comprehensive synthesis of mental health trajectories associated with the COVID-19 pandemic.
