Demographic characteristics of the sample.

* HDRS: Hamilton Depression Rating Scale; CRS: Clinical Rating of Severity; MIDAS: Migraine Disability Assessment; EDSS: Expanded Disability Status Scale; Hoehn & Yahr: Hoehn & Yahr Score; NIHSS: National Institutes of Health Stroke Scale; CGI: Clinical Global Impression (CGI); MMSE: Mini Mental State Examination; ADS: Alcohol Dependence Scale.
** In substance dependency, 44 persons had alcohol dependence as their main diagnosis. The data reported here refer to the 34 of those from whom the ADS data were available. Mean is not reported because of the low N. For all other substance dependency conditions, the intention was to collect data with the ‘Severity of Dependence Scale’. There were, however, a larger number missing data and the results are, therefore, not reported.
Demographic characteristics of the sample.

* HDRS：汉密尔顿抑郁量表（Hamilton Depression Rating Scale）；CRS：临床严重程度评定量表（Clinical Rating of Severity）；MIDAS：偏头痛残疾评估量表（Migraine Disability Assessment）；EDSS：扩展残疾状态量表（Expanded Disability Status Scale）；Hoehn & Yahr：霍恩-雅尔评分（Hoehn & Yahr Score）；NIHSS：美国国立卫生研究院卒中量表（National Institutes of Health Stroke Scale）；CGI：临床总体印象量表（Clinical Global Impression, CGI）；MMSE：简易精神状态检查量表（Mini Mental State Examination）；ADS：酒精依赖量表（Alcohol Dependence Scale）。
** 在物质依赖群体中，共有44名受试者以酒精依赖为主要诊断。本次报告的数据纳入其中34名可获取ADS数据的受试者。由于样本量较小，未报告其均值。针对其余各类物质依赖亚型，研究原计划采用依赖严重程度量表（Severity of Dependence Scale）开展数据采集，但因存在大量缺失数据，相关结果未予报告。
