Calculated - Total score based on an 8-item questionnaires ranking likelihood of dozing off Johns MW 1991 (PubMed ID: 1798888). Scale 0-3 for individual items; 0 to 24 for overall score. Algorithm: The ESS_SUENO is computed by adding ALL 8 ITEMS (SPEA12A TO SPEA12H). If any item is missing then ESS_SUENO is missing. Warning: The levels of each item need to be recoded as follows: No chance (from 1 to 0), slight chance (from 2 to 1), moderate chance (from 3 to 2) and high chance (from 4 to 3).Search for all ESS variables within this dataset
