A Randomized Trial Comparing Two Low-Intensity Psychological Interventions for Distressed Patients With Cancer and Their Caregivers
Purpose/Objectives: To compare the effectiveness of two low-intensity approaches for distressed patients with cancer and caregivers who had called cancer helplines seeking support. Baseline distress was hypothesized as a moderator of intervention effect.
Design: Randomized trial.
Setting: Community-based cancer helplines in Queensland and New South Wales, Australia.
Sample: 354 patients with cancer and 336 caregivers.
Methods: Participants were randomized to either a single session of nurse-led self-management intervention or a five-session psychologist cognitive behavioral intervention delivered by telephone. Assessments were undertaken at baseline (preintervention) and at 3, 6, and 12 months.
Main Research Variables: Psychological and cancer-specific distress and post-traumatic growth.
Findings: No significant moderation by baseline cancer-specific distress was noted. For low-education patients, only the psychologist intervention was associated with a significant drop in distress. For all other participants, distress decreased over time in both arms with small to large effect sizes (Cohen's ds = 0.05-0.82). Post-traumatic growth increased over time for all participants (Cohen's ds = 0.6-0.64).
Conclusions: Many distressed patients with cancer and their caregivers may benefit significantly from a single session of a nurse psychoeducation intervention that can be delivered remotely by telephone and supported by self-management materials. Research is needed to develop an algorithm that moves beyond the use of distress as the only indicator for referral to specialist psychological services. Survivors and caregivers with low education and low literacy may require more in-depth and targeted support.
Implications for Nursing: Brief nurse psychoeducation and stress management for cancer survivors and caregivers should be considered as part of a tiered approach to psychosocial care.
