Depression Screening in Patients Undergoing Radiation Therapy For Cancer

RATIONALE: Gathering information about depression in patients with cancer may help doctors learn more about the disease and plan the best treatment.

PURPOSE: This clinical trial is studying depression screening in patients undergoing radiation therapy for cancer.

OBJECTIVES:

Primary

* Assess the feasibility of a screening procedure for major depression in cancer patients undergoing definitive or palliative radiotherapy.

Secondary

* Establish the rates of major depression identified through diagnostic telephone interviews.
* Estimate the false negative rate (1-sensitivity) and false positive rate (1-specificity) of the 9-item Patient Health Questionnaire (PHQ-9) and the 25-item Hopkins Symptom Checklist (HSCL-25).
* Compare the false negative rate of 2 items addressing mood disturbance on the PHQ-9 relative to all 9-items on the PHQ-9 and to the HSCL-25.
* Examine the sensitivity to changes in depression severity of the PHQ-9, the HSCL-25, and the Structured Clinical Interview for DSM-IV (SCID) .
* Correlate both depressive symptoms and major depression in terms of sociodemographic and clinical variables.
* Establish the nature and adequacy of existing care, patient preferences, treatment availability, and barriers to depression treatment utilization for patients identified with major depression using the Assessment of Mental Health Services and Barriers to Care.
* Assess rates of continued elevations of depressive symptoms, seeking and receipt of care, and barriers to care at follow-up in these patients.
* Examine the differences in study objectives based on institution characteristics with regard to existing psychosocial services that are provided on-site and integrated in cancer care.

OUTLINE: This is a multicenter study.

* Depression screening: Patients complete screening depression questionnaires, including the Hopkins Symptom Checklist (HSCL-25) and the 9-item Patient Health Questionnaire (PHQ-9) that includes a 2-item PHQ, and a Health Status Questionnaire at baseline.
* Diagnostic telephone interview: Within 2 weeks, patients who screen positive for depression and select patients who screen negative for depression undergo a diagnostic telephone interview that includes modules of the Structured Clinical Interview for Diagnosis-DSM-IV (SCID) related to major depression, bipolar disorder, adjustment disorders, and queries concerning past and current mental health treatment and barriers to treatment. The Assessment of Mental Health Services and Barriers of Care questionnaire is also administered by the clinical interviewer. Clinical interviewers provide patients who are found to be depressed with a list of community resources, and offer assistance in obtaining treatment, if needed. Patients are also encouraged to discuss these options with their oncology health care team.
* Follow-up interview: At 3 months, patients who receive a research diagnosis of major depression, dysthymia, bipolar disorder, or cancer-related adjustment disorder in the initial SCID-DSM-IV undergo another diagnostic telephone interview and are reassessed for the initiation and continuation of treatment, current depressive symptoms, and receipt of cancer care. The HSCL-25, PHQ-9, and Assessment of Mental Health Services and Barriers of Care questionnaires and the SCID-DSM-IV are also administered by the clinical interviewer. Treatment options and referrals are discussed with patients who remain depressed and are not in treatment.
