Online mental health self-help services are of societal importance and increasingly popular. Therefore, we have developed an online platform offering free self-help to the Turkish public with modules based on Cognitive Behavioral Therapy (CBT) targeting depression, anxiety, and stress respectively. The main purpose of this study is to describe the user profile of this platform. A pre-intervention self-report assessment including general demographic information and the Brief Symptom Inventory questionnaire during October 2020 until September 2022. 8331 participants completed the assessment and created an account out of the 11.228 users who registered during a two-year period, of which 8.331 (74%) completed the assessment and created an account. The majority of these users were female (76.17%), highly educated (82%), single (68%) and actively studying or working (84%). Slightly more than half (57%) of the platform user had not received psychological assistance before, while those who did receive previous assistance indicate to have benefitted from that (74%). The psychological symptoms of users are widely distributed, encompassing a broad range of user profiles. Approximately half of all users actively used the platform, while the other half did not complete any module. Among active users, the course “coping with depressive mood” was the most popular (41.45%), followed by “coping with anxiety” (37.25%) and “coping with stress” (21.30%). Offering a free online CBT self-help platform to the Turkish public seems feasible, with strong uptake among both man and woman struggling with a variety of psychological symptoms. Further research is needed to assess user satisfaction and change in symptoms over time during platform use by means of a feasibility trial.

在线心理健康自助服务具有社会重要性并且越来越受欢迎。因此，我们开发了一个在线平台，为土耳其公众提供免费自助服务，其模块基于认知行为疗法（CBT），分别针对抑郁、焦虑和压力。本研究的主要目的是描述该平台的用户概况。干预前自我报告评估，包括 2020 年 10 月至 2022 年 9 月期间的一般人口统计信息和简要症状调查问卷。在两年期间注册的 11,228 名用户中，有 8331 名参与者完成了评估并创建了账户，其中8.331 (74%) 完成了评估并创建了帐户。这些用户大多数是女性（76.17%）、受过高等教育（82%）、单身（68%）和积极学习或工作（84%）。略多于一半（57%）的平台用户之前没有接受过心理援助，而那些曾经接受过心理援助的人表示曾从中受益（74%）。用户的心理症状分布广泛，涵盖广泛的用户画像。大约一半的用户积极使用该平台，而另一半则没有完成任何模块。在活跃用户中，“应对抑郁情绪”课程最受欢迎（41.45%），其次是“应对焦虑”（37.25%）和“应对压力”（21.30%）。向土耳其公众提供免费的在线 CBT 自助平台似乎是可行的，受到各种心理症状困扰的男性和女性的强烈接受。需要进一步研究通过可行性试验来评估用户满意度以及平台使用过程中症状随时间的变化。
