Panel Data Structural Equation Models. DV represents a generic outcome (Dependent) Variable; CI = participant has Chronic Illness, MH = Mental Health (SWEMWBS or KESSLER), S = Social provision score, R = specific social support (can Rely on someone when sick), L = Loneliness. Subscripts indicate the survey wave: 0 is the pre-pandemic wave, wave 1 is the first lockdown, wave 2 is between lockdowns, wave 3 is the third lockdown. Panel A shows the model used to estimate the trends in outcomes and mediators across the waves. Panel B shows the longitudinal mediation model (residual terms associated with endogenous variables are suppressed for brevity). For certain variables, a baseline measure (wave 0) is missing, in which case the model excludes the baseline variable and all paths associated with it
