Contrasting the three scoring approaches using data with simulated missingness among those with complete SRE data (n=516): Correlations of SRE summary scores from the three approaches with SRE summary scores from observed complete data and with “simulated alcohol-effect endorsement.”

Note. Only participants who were randomly assigned to have at least one missing score were included (n=228) because participants who were randomly assigned to have no missing scores (n=288) had exactly the same values across the four response-to-alcohol summary scores.
This is the number of non-missing items for a given participant, which in this case of simulated missingness was purely a function of the random assignment of different missing data patterns to different participants.
