Purpose: In young adult cancer survivors (YACSs) to explore the rate of being nonemployed and having low work ability, and to identify factors associated with these two outcomes. Methods: All Norwegian YACSs (N = 3558) diagnosed at ages 19–39 years and treated between 1985 and 2009 for breast or colorectal cancer, leukemia, non-Hodgkin lymphoma, or melanoma, and alive in 2015, were mailed a questionnaire. The response rate was 42%. For treatment, a minimal surgery-only group (N = 198) was defined as reference group, and 1000 YACSs represented the local, systemic, and systemic plus other treatment groups. Work status was compared with normative data. Results: The sample included 63% females. Median age at survey was 49 years (range 27–65), and median time since first cancer diagnosis was 16 years (range 6–31). At survey, 25% (95% confidence interval [CI]: 22–27) of YACSs were nonemployed, and 38% (95% CI: 35–41) reported low work ability. The rate of being nonemployed was similar to normative data. More female YACSs held disability pension compared with normative data. In multivariable analyses, an increasing number of adverse effects (AEs), cardiovascular diseases, lower basic education, reduced level of self-rated health, and increased level of depression were significantly associated with both being nonemployed and having low work ability. Conclusions: In YACSs surveyed at median 49 years of age, 25% were nonemployed and 38% had low current work ability. An increased mean number of long-term AEs and several other health-related factors were significantly associated with both these outcomes. Health care providers responsible for YACSs should be attentive to such factors and work ability.

Background: Population-based reference data on frequently used questionnaires are important for comparative purposes. Due to changes in health and lifestyles, such data should be updated every other decade. The objectives of this study were to establish Norwegian population-based reference data on the Fatigue Questionnaire (FQ) and the Patient Health Questionnaire-9 (PHQ-9) on depression, to compare the FQ-scores with our previous reference data from 1996, and to explore the relationship between the scores on these two instruments. Methods: In 2015, a representative sample of 6,012 Norwegians aged 18–80 years was mailed a questionnaire including the FQ and the PHQ-9, and 36% responded. Complete FQ-scores were delivered by 2,041 subjects, and complete PHQ-9 scores by 2,086 subjects. The scores are displayed according to sex and 10-year age groups. Results: Few 2015 mean scores of mental, physical, and total fatigue differed significantly from those of 1996, and the same was found for the prevalence rates of chronic fatigue. The exception was a significantly lower prevalence in 2015 of mean fatigue scores and prevalence of chronic fatigue in females ≥ 60 years. The prevalence of major depressive episode (MDE) based on the PHQ-9 sum score cut-off ≥ 10 was 5.9% for males and 9.8% for females, and 2.5% and 3.8% using a DSM-based algorithm with at least five endorsed criteria including either anhedonia or depressed mood. The correlation between the FQ and the PHQ-9 was 0.59, implying 36% shared variance. Conclusions: This study showed considerable interrelationship between the FQ and the PHQ-9 constructs. The reference data show that scores on the FQ have only improved significantly in persons aged 60 or more years between 1996 and 2015. Our prevalence findings of MDE based on the PHQ-9 are in accordance with the findings from other countries. The FQ and the PHQ-9 should be used together in epidemiological and clinical studies.

232 family members from 27 Norwegian families with BRCAl mutations were offered genetic testing. 180/232 (78%) chose to be tested, 14/232 (6%) have not yet decided and 38/232 (16%) declined. All 232 persons were invited to fill in the following questionnaires when offered testing: Impact of Event Scale (IES), Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire (GHQ‐28) and Beck Hopelessness Scale (BHS). 207/232 (89%) responded to the questionnaires. Of those declining to be tested 23/38 (61%) answered the questionnaires compared to 170/180 (94%) of those wanting the test (p < 0.0001).A higher proportion of females with a history of cancer than females without such a history had abnormal scores on the IES‐intrusion and GHQ questionnaires (p < 0.001). Healthy females who were deciding on predictive testing had the same or lower prevalence of mental distress compared to the general population, between 4.3% and 18.0% as measured by the different questionnaires. Males did not differ from healthy females on any of the measures.According to their HADS scores, women without a history of cancer deciding on predictive testing for breast‐ovarian cancer had lower or equal levels of mental distress compared to the general population. The high uptake of genetic testing combined with the lower than normal prevalence of mental distress indicates that the activity may continue as practised, awaiting longitudinal data concerning the levels of mental distress after genetic testing.
