Psychological distress and use of psychosocial support in familial adenomatous polyposis.

OBJECTIVE

Familial adenomatous polyposis (FAP) is characterized by multiple adenomas in the colorectum with a high risk to develop colorectal cancer. It is unclear whether individuals at risk of FAP experience distress due to this potentially life-threatening disease. This nationwide study assessed: (1) the prevalence of psychological distress; and (2) the need for and use of specialized professional psychosocial support.

METHODS

In this cross-sectional study, all individuals from families at high risk for FAP registered at the Netherlands Foundation for the Detection of Hereditary Tumours were invited to complete a questionnaire assessing, among other issues, generalized, cancer-specific and FAP-specific distress.

RESULTS

In total, 525 individuals completed the questionnaire. Approximately 20% of the respondents had moderate to severe levels of FAP-specific distress. Levels of generalized distress were comparable to the general Dutch population. Significantly more individuals with a FAP diagnosis had frequent cancer worries than those at risk of FAP or non-carriers (p=0.02). Distress levels were more strongly associated with psychosocial variables (e.g. perceived cancer risk), than with sociodemographic or clinical variables. Up to 43% of the variance in distress could be explained by all variables combined. Of those moderately to severely distressed, 26% had received specialized professional psychosocial support, while 30% of those did not receive the support they wanted.

CONCLUSIONS

A substantial minority of individuals reported moderate to severe distress levels associated with FAP. However, only one-third of those received specialized professional psychosocial support. We recommend the use of a screening questionnaire to identify individuals in need of such support.
