Overview

PHQ-9 may support adjusted depression screening across cancers; cross-sectional data leaves prospective validity and outcome prediction open.

Structured PICO

P
Population
2,059 cancer patients with varying diagnoses 6 months after discharge from a German rehabilitation clinic, and a representative sample of 2,693 people from the general population matched for age and gender.
I
Intervention
Assessment of depression using the Patient Health Questionnaire (PHQ-9)
C
Comparator
General population controls
O
Outcome
Psychometric properties of the PHQ-9 (reliability, factorial structure) and unbiased estimates of depression burden across cancer typespatient reported

The PHQ-9 is a reliable tool for assessing depression in cancer patients, and adjusting for age and gender is crucial for unbiased comparisons of depression burden across different cancer types.

Limitations

  • Examined half a year after discharge from a rehabilitation clinic (potential selection bias)
  • No information on non-participants
  • Limited information on health status of respondents
  • Rehabilitation participants not totally representative of all cancer patients
  • Small sample sizes for some patient groups
