The risk of suicide is approximately two times higher in patients with breast cancer compared to the general population. Suicide risk factors are widely investigated but research on the protective factors is lacking. We investigated whether each subscale of grit, consistency of interest, and perseverance of effort, could serve as a protective factor against suicidality.
Participants were recruited at the Stress Clinic for Cancer Patients, a psycho-oncology clinic at Asan Medical Center from May 2019 to March 2021. A total of 140 female patients with breast cancer completed self-administered questionnaires including Grit scale, Distress thermometer, and Mini International Neuropsychiatric Interview (MINI) suicidality module. We used PROCESS macro for analyzing the mediation model to identify the protective factors for suicidality.
Our findings showed that perseverance of effort showed statistically non-significant associations with psychological distress (p=0.403) and suicidality (p=0.945), however, consistency of interest decreased suicidality through psychological distress (β=-0.015; 95% confidence interval, -0.035 to -0.002).
The result shows that consistency of interest can be a protective factor against suicidality by reducing psychological distress.
与普通人群相比，乳腺癌患者的自杀风险大约高出两倍。自杀风险因素已得到广泛研究，但对保护因素的研究却很缺乏。我们调查了坚毅的各个子量表，即兴趣的一致性和努力的坚持性，是否可以作为预防自杀倾向的保护因素。
2019年5月至2021年3月，在峨山医学中心的心理肿瘤门诊——癌症患者压力诊所招募参与者。共有140名女性乳腺癌患者完成了自我管理问卷，包括坚毅量表、痛苦温度计和迷你国际神经精神病学访谈（MINI）自杀倾向模块。我们使用PROCESS宏分析中介模型，以确定自杀倾向的保护因素。
我们的研究结果表明，努力的坚持性与心理困扰（p=0.403）和自杀倾向（p=0.945）之间在统计学上无显著关联，然而，兴趣的一致性通过心理困扰降低了自杀倾向（β=-0.015；95%置信区间，-0.035至-0.002）。
结果表明，兴趣的一致性可以通过减轻心理困扰成为预防自杀倾向的保护因素。
