Abbreviation: PDCDS, Post-Discharge Coping Difficulty Scale.
Includes 457 intervention and 460 control participants (owing to failure to complete the 14-day telephone call), unless otherwise indicated.
Score ranges from 0 to 100, with high scores indicating more difficulty coping. Marginal means and differences in the PDCDS score are obtained from linear regression models, adjusted for stratification factors (neighborhood poverty and state). The 95% CIs for the difference include the null-hypothesized value of 0.
Marginal means and ratio for time until return to normalcy are obtained from censored Poisson regression models with a bound at 15 days for those parents who had not returned to normal at the 14-day call, adjusted for stratification factors. The 95% CIs for the ratio include the null-hypothesized value of 1.
Includes 458 intervention participants.
Marginal means and ratio for number of red flags recalled are obtained from Poisson regression models, adjusted for stratification factors and the number of potentially correct answers for the patient’s condition. The 95% CIs for the ratio exclude the null-hypothesized value of 1.
Includes 417 intervention and 444 control participants.
