Sleep\u2010severity profiles were derived by principal component analysis of the PSQI components and hierarchical clustering, and their diagnostic composition was compared by chi\u2010squared test. Psychological outcomes were reduced based on their intercorrelation structure and analysed by two\u2010way MANCOVA (Profile \u00d7 TMD status), covarying age and sex.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Two profiles emerged: Mild\u2013Moderate (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200959; PSQI M\u2009=\u20095.25) and Severe Poor Sleepers (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200921; PSQI M\u2009=\u20099.19), TMD being concentrated in the Severe profile (\u03c7\n                      <jats:sup>2<\/jats:sup>\n                      (1)\u2009=\u20099.35,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002). The outcomes reflected a single general\u2010distress dimension indexed by the SCL\u201090\u2010R Global Severity Index (GSI). GSI therefore served as the primary outcome, with body vigilance and affect tested with that dimension partialled out. Profile and Profile \u00d7 TMD effects were significant (TMD main effect, n.s.), both carried by general distress: distress was elevated in the Severe profile (\u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p\u2009=\u20090.17), and the interaction (\u03b7\n                      <jats:sup>2<\/jats:sup>\n                      p\u2009=\u20090.16) reflected distress rising with sleep severity in controls but uniformly elevated in TMD.
