Canadian public safety personnel (PSP) experience high rates of mental health disorders and face many barriers to treatment. Internet-delivered cognitive behavioral therapy (ICBT) overcomes many such barriers, and is effective for treating depression, anxiety, and posttraumatic stress disorder (PTSD) symptoms.
This study was designed to fill a gap in the literature regarding the use of ICBT tailored specifically for PSP. We examined the effectiveness of a tailored ICBT program for treating depression, anxiety, and PTSD symptoms among PSP in the province of Saskatchewan.
We employed a longitudinal single-group open-trial design (N=83) with outcome measures administered at screening and at 8 weeks posttreatment. Data were collected between December 5, 2019 and September 11, 2020. Primary outcomes included changes in depression, anxiety, and PTSD symptoms. Secondary outcomes included changes in functional impairment; symptoms of panic, social anxiety, and anger; as well as treatment satisfaction, working alliance, and program usage patterns.
Clients reported large symptom reductions on measures of depression and anxiety, as well as moderate reductions on measures of PTSD and secondary symptoms, except for social anxiety. Most clients who reported symptoms above clinical cut-offs on measures of depression, anxiety, and PTSD during screening experienced clinically significant symptom reductions. Results suggested good engagement, treatment satisfaction, and working alliance.
Tailored, transdiagnostic ICBT demonstrated promising outcomes as a treatment for depression, anxiety, and PTSD among Saskatchewan PSP and warrants further investigation.

加拿大公共安全人员（PSP）心理健康障碍发生率高，且面临许多治疗障碍。互联网认知行为疗法（ICBT）克服了许多此类障碍，对治疗抑郁、焦虑和创伤后应激障碍（PTSD）症状有效。
本研究旨在填补针对 PSP 专门设计的 ICBT 使用文献中的空白。我们考察了为萨斯喀彻温省 PSP 量身定制的 ICBT 方案治疗抑郁、焦虑和 PTSD 症状的有效性。
我们采用纵向单组开放试验设计（N=83），在筛选和治疗 8 周后进行结果测量。数据收集于 2019 年 12 月 5 日至 2020 年 9 月 11 日之间。主要结局包括抑郁、焦虑和 PTSD 症状的变化。次要结局包括功能障碍、恐慌、社交焦虑和愤怒症状的变化，以及治疗满意度、工作联盟和方案使用模式。
客户报告称，在抑郁和焦虑测量方面的症状大幅减轻，在 PTSD 和次要症状测量方面的症状中度减轻，除了社交焦虑。在筛选时报告抑郁、焦虑和 PTSD 测量值超过临床临界值的症状的大多数客户经历了临床显著的症状减轻。结果表明良好的参与度、治疗满意度和工作联盟。
针对萨斯喀彻温省 PSP 的量身定制、跨诊断 ICBT 显示出作为治疗抑郁、焦虑和 PTSD 的有前途的结果，值得进一步研究。
