Anxiety and depression among long-term survivors of cancer in Australia: results of a population-based survey.

OBJECTIVE

To assess the prevalence and predictors of anxiety and depression among a heterogeneous sample of long-term adult cancer survivors.

DESIGN AND PARTICIPANTS

Cross-sectional survey of 863 adults diagnosed with a new histologically confirmed cancer (local or metastatic) between 1 April and 30 November 1997 and still alive in 2002, living in NSW, able to read and understand English adequately, physically and mentally capable of participating, and aware of their cancer diagnosis, who were randomly selected from the New South Wales Central Cancer Registry.

MAIN OUTCOME MEASURES

Prevalence of anxiety and depression assessed by the Hospital Anxiety and Depression Scale; and factors (patient, disease, and treatment characteristics; coping style; social support) predicting clinical or borderline levels of anxiety and depression.

RESULTS

Levels of anxiety and depression were low; only 9% of participants reported clinically important levels of anxiety and 4% reported depression. The strongest predictive factors of borderline or clinical anxiety were previous treatment for psychological illness, maladaptive coping styles (helplessness-hopelessness, anxious preoccupation) and poor social support. Borderline or clinical depression was most strongly predicted by previous treatment for psychological illness, being an invalid pensioner, maladaptive coping style (helplessness-hopelessness) and poor positive social interaction.

CONCLUSIONS

By 5 years after diagnosis, most survivors had adjusted well to their cancer experience, with levels of anxiety and depression similar to those of the general population. Nevertheless, a small and important group of long-term survivors continue to experience adverse psychological effects and need assistance. Monitoring of psychological wellbeing and referring patients when appropriate need to be integrated into routine care for cancer survivors.
