Coping and Self-Efficacy Mediate Mood Improvements in Brain Tumor Caregivers

Caregivers of patients with primary malignant brain tumors manage a unique constellation of clinical challenges, including the rapid cognitive and physical decline of their loved ones [1, 2]. The psychological burden in this population is substantial, with nearly 40% to 48% of caregivers experiencing clinically significant symptoms of anxiety and depression [3]. Despite the devastating impact of these tumors on the family unit, evidence-based supportive care resources tailored specifically to the neuro-oncology setting have historically been limited [4, 3]. While data from a randomized controlled trial of 120 caregivers demonstrate that a six-session telehealth intervention can significantly reduce anxiety (p = 0.008) and depression (p = 0.004), the specific mechanisms driving these improvements require further investigation [5, 4]. A recent secondary analysis now examines the specific psychological pathways, such as improved coping ability (a mediator accounting for 75% of the total intervention effect on anxiety), through which this targeted intervention exerts its therapeutic effects [6, 7].
