Handling of missing data and summary scores: For those subjects with more than 50 % of the questions answered, a prorated individual total was calculated using the formula Prorated total = (Sum of question scores) x (n of questions in the subscale)/(n of questions answered). Those subjects with 50 % or more of the questions not answered were given a missing value for the scale. Domain scores were then calculated as the sum of the scores for each question within the factor and the network average score used in further analyses in the broader study
