Multisite Randomized Controlled Trial of CareSTEPS: A Supportive Care Intervention for the Family Caregivers of Patients With Advanced Lung Cancer.

Objectives: Patients with advanced lung cancer (LC) face significant physical, psychological, and functional challenges, increasing their reliance on caregivers for practical and emotional support. This study evaluates the efficacy of CareSTEPS (Self-Care, Stress management, Symptom management, Effective communication, Problem-solving, and Social support), a 6-week telephone-delivered intervention designed to improve psychological functioning (depression and anxiety symptoms) and reduce caregiver burden among family caregivers of patients with advanced LC. Methods: In this multisite, open-label, parallel-group randomized controlled trial, 174 caregivers (74.1% female individuals, 40.2% from a racial or ethnic minority group) of patients with stage IIIB or IV NSCLC or extensive-stage SCLC completed baseline surveys and were randomly assigned to CareSTEPS (n = 87) or usual care (n = 87) using stratified block randomization. Caregivers in the CareSTEPS arm received a manual with information on self-care, stress management, symptom management, effective communication, problem-solving, and social support. They also participated in six weekly telephone sessions with Masters-level trained interventionists with a mental health background, who provided psychoeducation, skills training, and support. Eight weeks after baseline, caregivers completed a follow-up survey. Results: Using an intent-to-treat framework, analyses of covariance were conducted to assess the efficacy of CareSTEPS, with Conclusions: The CareSTEPS intervention reports great promise in meeting the critical support needs of the family caregivers of patients with advanced LC, significantly improving caregivers' psychological functioning and reducing their burden. Overall, the findings emphasize the importance of incorporating caregiver support into the comprehensive management of advanced LC. Clinical Trial Registration: ClinicalTrials.gov NCT02414672.
