However, to the authors' knowledge, it remains unclear whether threatening IPs that are consistent with disease severity are equally harmful.

Clinical and survival data were collected through the Netherlands Cancer Registry. Subgroups were defined by IPs (Brief Illness Perception Questionnaire) and prognosis (conditional 5\u2010year relative survival) into survivors with 1) IPs consistent with prognosis (\u201crealistic\u201d); 2)  less threatening IPs than expected based on prognosis (\u201coptimistic\u201d); and 3) more threatening IPs than expected based on prognosis (\u201cpessimistic\u201d).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      Compared with survivors with realistic IPs (1230 survivors), those with optimistic IPs (582 survivors) were found to have a higher HRQOL (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.01 on all European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 [EORTC QLQ\u2010C30] scales) and a lower all\u2010cause mortality (hazard ratio, 0.72;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.01), whereas those with pessimistic IPs (645 survivors) had a lower HRQOL (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.01 on all scales) and a higher all\u2010cause mortality (hazard ratio, 1.52;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.01).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>\n                      Optimistic IPs are associated with better HRQOL and survival, even if they may appear to be unrealistic with respect to cancer survivors' prognosis.
