(author)Research to establish (work related) risk factors of sickness absence is usually restricted to self-reported measures of sickness absence. When risk factors and outcome measures are both collected with self-administered questionnaires, however, this may suffer from monomethod bias. In the current research, absence was measured both with self...article 2010
