Purpose: Adolescent and young adult (AYA) patients with cancer have few opportunities to connect with patients of the same generation while hospitalized. Although anxiety is frequently reported by them, there are no reports on the psychological effectiveness of an in-hospital patient support program based on peer support. This study aimed to evaluate the effectiveness of a program, termed Adolescent and Young Adult Hiroba (AYA Hiroba), for anxiety in AYA patients with cancer. Methods: This single-center, prospective, observational study in 24 AYA patients with cancer was conducted at the National Cancer Center Hospital in Japan. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) was used to evaluate the primary outcome, anxiety. The Distress Thermometer (DT) was used to evaluate the secondary outcome, distress. The two outcomes were assessed before and after participation in AYA Hiroba. The Net Promoter Score (NPS) was used to evaluate satisfaction after participation in AYA Hiroba. Participants' free-text descriptions of the program were categorized according to similarities and differences. Results: The HADS-A and DT scores were significantly lower after the program than before (p < 0.001), as was the percentage of AYA patients with cancer with high distress (p = 0.04). The NPS was 27, which was lower than the value of 52 obtained in our previous study. Requests and suggestions to improve the program were grouped into three categories: content, facilitation, and online connection environment. Conclusion: This study suggests the preliminary effectiveness of the in-hospital peer support program for anxiety in AYA patients with cancer. The Clinical Trial Registration number: UMIN000045779.

院内同伴支持计划青少年 Hiroba 对青少年癌症患者焦虑的初步效果。

目的：患有癌症的青少年和青年 (AYA) 患者在住院期间很少有机会与同代患者建立联系。尽管他们经常报告焦虑，但没有关于基于同伴支持的住院患者支持计划的心理有效性的报告。本研究旨在评估一项名为青少年和青年 Hiroba (AYA Hiroba) 的计划对治疗 AYA 癌症患者焦虑症的有效性。方法：这项单中心、前瞻性、观察性研究是在日本国家癌症中心医院对 24 名 AYA 癌症患者进行的。使用医院焦虑和抑郁量表-焦虑（HADS-A）来评估主要结果——焦虑。应激温度计（DT）用于评估次要结果——应激。在参加 AYA Hiroba 之前和之后评估了这两个结果。净推荐值 (NPS) 用于评估参与 AYA Hiroba 后的满意度。参与者对项目的自由文本描述根据相似点和差异进行分类。结果：项目结束后，HADS-A 和 DT 评分显着低于项目前 (p < 0.001)，AYA 癌症患者高度痛苦的百分比也是如此 (p = 0.04)。NPS 为 27，低于我们之前研究中获得的 52 值。改进该计划的请求和建议分为三类：内容、便利性和在线连接环境。结论：本研究表明院内同伴支持计划对 AYA 癌症患者的焦虑具有初步效果。临床试验注册号：UMIN000045779。
