Background: The Screening Inventory of Psychosocial Problems (SIPP) is a short, validated self-administered questionnaire to identify psychosocial problems in cancer patients. The one page 24-item questionnaire assesses physical complaints, psychological complaints, and social and sexual problems. There is very little known about the effectiveness of using the SIPP in consultation settings.
Aim: The aim of this study is to test the hypothesis that using the SIPP may prevent underdiagnosis of early symptoms reflecting psychosocial problems, should facilitate communication between physicians and patients about psychosocial distress and may contribute to adequate referral to relevant psychosocial caregivers.
Methods: A Cluster Randomized Controlled Trail (CRCT) is developed using a Solomon four-group design (two intervention and two control groups) to evaluate the effects of using the SIPP. Radiotherapists instead of patients are at random allocated to experimental or control groups. All included patients are randomized into the groups with and without pre-measurement. Psychosocial distress, quality of life, patients' satisfaction about communication with their radiotherapist during first consultation and the number and type of referred patients to psychosocial caregivers are assessed. Self-administered assessments are conducted at four times: pre-test before first consultation (T1), and post-tests directly following the first consultation (T2), three months (T3) and one year after (T4) the first measurement. Medical information are gathered from patients' medical records. Furthermore, a process evaluation is carried out.
Relevance: Using the SIPP may lead to a reduction of psychosocial problems and better quality of life, both on the short and long term. If the SIPP proves to be effective, the results of this project may contribute to motivate health care workers to use the SIPP as a standard method for early detection of psychosocial distress in oncology departments in the Netherlands and abroad.
