Abstract Purpose Personality traits, particularly neuroticism, have an impact on people’s health and lifestyle. Due to lack of previous studies, we examined old cancer survivors (OCSs) versus cancer-free age-matched controls aged ≥ 70 years, regarding prevalence of high neuroticism, health problems in those with high and low neuroticism, and sociodemographic and clinical variables that were significantly associated with high neuroticism. Methods We merged data from a Norwegian population–based health study (the HUNT-3) and from the Cancer Registry of Norway identifying OCSs. Three cancer-free controls were drawn at random for each OCS. Neuroticism was self-rated on a brief version of Eysenck Personality Questionnaire. Between-group statistical comparisons were made between OCS and controls, and among their subgroups with high and low neuroticism. Logistic regression analyses were used to investigate independent variables significantly associated with high neuroticism. Results Twenty-nine percent of OCSs reported high neuroticism while controls reported 30%. OCSs showed significantly lower rate of good life satisfaction than controls. All other between-group comparisons were nonsignificant. Being OCSs was not significantly related to high neuroticism in the regression analyses. Sociodemographic, general health, and lifestyle issues, lack of energy, and low life satisfaction remained significantly associated with high neuroticism in the multivariable analysis. Conclusions The prevalence of high neuroticism was similar in OCSs and controls. High neuroticism was associated with negative health and lifestyle issues in both groups. Keywords Neuroticism .

Introduction Cancer epidemiology shows that the number of old cancer survivors (≥ 70 years) (OCSs) is increasing [5, 34]. Compared to age-matched controls without cancer, OCSs report more health problems, reduced health-related quality of life (HRQoL), and more functional impairment [6, 24, 32, 33]. Previously we have studied how OCSs deal with activities of daily living (ADL-problems) and eventual consequences of

cancer and its treatment [19]. Problems with instrumental ADL are significantly more common in OCS compared with controls (28.5% versus 21.4%). Additionally, when comparing OCS and controls, for female, those in paired relationship, reporting poor self-rated health, hospitalization last year, and low level of neuroti
