Background and Aims: Breast cancer not only affects physical health but also impacts psychological well-being and quality of life. Reduced meaning in life, emotional disturbances, and fatigue are common consequences. Therefore, investigating effective psychological interventions to enhance quality of life and meaning in life is essential. This study aimed to compare the effectiveness of mindfulness-based cognitive therapy and positive psychotherapy on meaning in life and quality of life in women with breast cancer.
Materials and Methods: This quasi-experimental study employed a pretest–posttest design with follow-up and a control group. The sample included 45 women with breast cancer attending hospitals in Tehran, Iran, during 2023–2024, randomly assigned into three groups (two intervention groups and one control group). Participants completed the Meaning in Life and Quality of Life questionnaires. Data were analyzed using repeated-measures multivariate analysis of variance (MANOVA) to assess the effects of group, time, and the group-by-time interaction.
Results: The findings indicated that both interventions significantly improved meaning in life and quality of life, compared to the control group (p < 0.01). However, the effect size at follow-up demonstrated greater durability of mindfulness-based cognitive therapy (MBCT) than positive psychotherapy. Specifically, MBCT showed larger effect sizes than positive psychotherapy for meaning in life (0.501 vs. 0.256) and for the quality-of-life domains of physical functioning (0.581 vs. 0.372) and role limitations due to physical problems (0.740 vs. 0.470), indicating a more sustained treatment effect (p < 0.01).
Conclusion: The findings suggest that both therapeutic approaches were effective; however, mindfulness-based cognitive therapy demonstrated greater effectiveness and longer-lasting effects than positive psychotherapy. These results may inform the development of psychological interventions and supportive care programs for patients with breast cancer
