There is a paucity of research into the relationship between personality and health behaviors among cancer survivors. The aim of this study was to investigate whether Type D personality and its two constituent components, negative affectivity (NA) and social inhibition (SI), are associated with health behaviors, quality of life (QoL) and mental distress among colorectal cancer (CRC) survivors.
Population-based study among 2620 CRC patients diagnosed between 2000-2009 who completed measures of personality (DS14), health behaviors, QoL (EORTC QLQ-C30) and mental distress (HADS).
Personality was not associated with BMI or smoking. Those scoring high on NA (with or without SI) were more often non-drinkers and less physically active compared to those scoring high on neither or only SI. Personality (high scores NA) and health behaviors (inactivity) were independently associated with poor QoL and mental distress.
Conclusions: CRC survivors with high scores on NA are at risk to be inactive and have worse health outcomes.
