a Mean (SE) of ecological momentary assessment (EMA) of emotional state data, as entered by users on an ad-hoc basis in the eB2 monitoring app. The vertical dotted line represents the declaration of a national emergency (and associated lockdown measures) in Spain on 14/03/20. Vertical shading represents weekends (Saturday and Sunday). b Within-user temporal networks, pre- and post- imposition of lockdown conditions. The same N = 22 users were included in each model. The pre-lockdown model included 324 observations across 36 time points (days), and the post-lockdown model included 122 observations over 34 days. Blue lines represent positive predictive values for a given variable on day n on the value of the connected variable on day n + 1, in the direction indicated by the arrowhead. Edges (connections between nodes) that do not significantly differ from 0 at alpha = 0.05 are not depicted. c Between-users networks, representing covariance of means across participants, pre- and post- lockdown (derived from the same data as b).
