    Average (95% CIs) total difficulties score (Strengths and Difficulties Questionnaire) over time by Index of Multiple Deprivation (<i>N</i> = 8,518).

    No full text
    Footnote: Time was modelled as a continuous variable; time points reflect the mean return time (in months) within each time window. The model was adjusted for SARS-CoV-2 PCR result. The individual-level random effect and residual variance are 32.0 and 9.60, respectively, giving an ICC of 0.77. (TIF)</p

    *Give information separately for exposed and unexposed groups. Note: An Explanation and Elaboration article discusses each checklist item and gives methodological background and published examples of transparent reporting. The STROBE checklist is best used in conjunction with this article (freely available on the Web sites of PLoS Medicine at http://www.plosmedicine.org/, Annals of Internal Medicine at http://www.annals.org/, and Epidemiology at http://www.epidem.com/). Information on the STROBE Initiative is available at http://www.strobe-statement.org. (DOCX)</p

    Average (95% CIs) total difficulties score (SDQ) over time (<i>N</i> = 8,518), shown from models for the whole population, by age, sex, and EHCP status.

    Footnote: Time was modelled as a continuous variable; dates reflect the mean questionnaire return time. All models adjusted for initial SARS-CoV-2 PCR result (i.e., trajectories in figure are for test-negatives). The intraclass correlations for the models was 0.77 (total population, by age group and EHCP) and 0.76 (by sex). CI, confidence interval; EHCP, educational health and care plan; SARS-CoV-2, Severe Acute Respiratory Syndrome Coronavirus 2; SDQ, Strengths and Difficulties Questionnaire.</p

    Average (95% CIs) total difficulties score (SDQ) over time by prior mental health (<i>N</i> = 8,518).

    Footnote: Time was modelled as a continuous variable; time points reflect the mean questionnaire return time (in months) within each time window. The model was adjusted for SARS-CoV-2 PCR result. The individual-level random effect and residual variance are 22.5 and 9.56, respectively, giving an intraclass correlation of 0.70. CI, confidence interval; SARS-CoV-2, Severe Acute Respiratory Syndrome Coronavirus 2; SDQ, Strengths and Difficulties Questionnaire.</p

    Average (95% CIs) total difficulties score (Strengths and Difficulties Questionnaire) over time by ethnic group (<i>N</i> = 8,518).

    Model coefficients from mixed-effects (random intercept) models: Total SDQ score over time for the whole sample and from models with interactions between time and age, sex, ethnicity, IMD, EHCP status, prior mental health, prior physical health, and baseline PCR status (<i>N</i> = 8,518).

    Note. Separate models were fitted to explore associations between time on total SDQ score (Model 0) and also by age (Model 1), sex (Model 2), ethnicity (Model 3), IMD (Model 4), EHCP (Model 5), prior mental health (Model 6), prior physical health (Model 7), and baseline PCR status (Model 8). Models 0–7 were additionally adjusted for baseline SARS-CoV-2 PCR result. CI = confidence interval; EHCP = educational health and care plan; IMD = Index of Multiple Deprivation; ref = reference category; SDQ = Strengths and Difficulties Questionnaire; SE = standard error.
