Adjusted odds ratios with 95% confidence intervals for predictors of increased psychological stress during COVID-19 lockdown measures. The shaded area represents variables that were not assessed in the adolescent sample, and therefore could not be considered as predictors for the adolescent model. Adjusted odds ratio was according to the logistic regression model, with covariates of baseline stress level and age. Reduced logistic regression adolescent model: covariate baseline stress level odds ratio 0.62, 95% CI 0.57–0.68, P < 0.001. Reduced logistic regression parental model: covariate baseline stress level odds ratio 0.65, 95% CI 0.60–0.71, P < 0.001; covariate parental age odds ratio 1.02, 95% CI 0.99–1.04, P = 0.16. ^aAssessed with the Procrastination Questionnaire for Students (Prokrastionationsfragebogen für Studierende). ^bAssessed with the short form of the Difficulties in Emotion Regulation Scale. ^cAssessed with the Parenting Self-efficacy Questionnaire (Fragebogen zur Selbstwirksamkeit in der Erziehung). ^dAssessed with the Perceived Stress Scale (PSS-4). ^eNot included in final model after backwards elimination of predictors.
