Extracted Data From: Mental Health Client-Level Data

This submission includes publicly available data extracted in its original form. Please reference the Related Publication listed here for source and citation information If you have questions about the underlying data stored here, please contact SAMHSA at [e-mail] Details: The Mental Health Client-Level Data (MH-CLD) and the Mental Health Treatment Episode Data Set (MH-TEDS) systems provide information on demographic and socioeconomic characteristics, clinical attributes (including mental health diagnoses and substance use), and National Outcome Measures (NOMs).Where do the data come from?: Providers and facilities funded or operated by SMHAs report their data to their SMHA. SMHAs are responsible for reporting MH-CLD/MH-TEDS data to SAMHSA.Data limitations: The data limitations include the following:MH-CLD represents clients receiving publicly funded mental health and support services.The scope of providers and facilities reporting data varies across states.The mental health diagnoses in the dataset may not represent all diagnoses for individuals who are served. Some individuals have no valid mental health diagnosis reported. If the missing diagnosis is not randomly distributed across providers and/or facilities, estimated prevalence rates of mental health diseases may be biased.National outcome measures are reported by states based on state definitions as per block grant statute.Confidentiality protection: Several measures are taken to protect the confidentiality of all records.Disclosure analysis is used to identify records that have unique combinations of key (mostly) demographic variables that could link a record to an individual.The original location of these records in MH-CLD is changed. If this is not sufficient to satisfy confidentiality standards, further recoding is done on other key variables. The recoding of variables including location is kept minimal, leaving nearly all the data intact. The analysis of the public-use file should not be affected.\"Quote from https://www.samhsa.gov/data/data-we-collect/mh-cld-mental-health-client-level-data/about.

本提交内容包含以原始形式提取的公开可用数据。如需获取数据来源与引用规范，请参阅此处列出的相关出版物。若您对本数据集存储的原始数据存在疑问，请联系美国药物滥用与精神卫生服务管理局（Substance Abuse and Mental Health Services Administration, SAMHSA），联系邮箱为[e-mail]。

详细说明如下：心理健康服务对象级数据（Mental Health Client-Level Data, MH-CLD）与心理健康治疗事件数据集（Mental Health Treatment Episode Data Set, MH-TEDS）系统可提供人口统计学与社会经济特征、临床属性（涵盖精神疾病诊断与物质使用状况）以及国家结局指标（National Outcome Measures, NOMs）相关信息。

数据来源：本数据由州级精神卫生服务管理局（State Mental Health Authorities, SMHAs）资助或运营的服务商与机构向所属SMHAs上报数据，再由SMHAs负责将MH-CLD与MH-TEDS数据汇总上报至SAMHSA。

数据局限性：本数据集存在以下局限：
1. MH-CLD仅覆盖接受公共资助的精神卫生服务与支持服务的服务对象；
2. 上报数据的服务商与机构覆盖范围存在州际差异；
3. 本数据集记录的精神疾病诊断未必覆盖服务对象的全部诊断情况，部分个体未报告有效的精神疾病诊断。若诊断缺失的分布在不同服务商或机构间并非随机，则精神疾病患病率的估计值可能存在偏倚；
4. 国家结局指标由各州依据整笔拨款法规规定的州级定义进行上报。

保密保护措施：为保障所有记录的保密性，本数据集采取了多项防护手段：
1. 开展披露风险分析，识别出包含独特关键（多数为人口统计学）变量组合、可能将记录关联至特定个体的条目；
2. 修改MH-CLD数据集中此类条目的原始位置信息；
3. 若前述措施仍未达到保密标准，则对其他关键变量进行进一步的重新编码。本次变量（含地理位置信息）的重新编码均保持最小化，尽可能保留了全部原始数据的完整性，且不会对该公开使用文件的分析工作造成影响。
