Assessing substance use of homeless persons is a critical task. This study examines the test-retest reliability, concurrent validity, and sensitivity to change of the Time-Line Follow-Back interview, a calendar instrument used to assess days and quantities of alcohol use and days of illicit drug use, in the multisite Collaborative Program to Prevent Homelessness (CPPH). The Time-Line Follow-Back was reliable for assessing use during the past month and the recent 6 months. Results from the Time-Line Follow-Back were correlated with other self-reports of use, with research diagnoses of substance use disorder, and with clinician ratings of severity of substance abuse. The Time-Line Follow-Back detected changes in clients with severe mental illness and in those with less severe psychiatric problems.
评估无家可归者的物质使用情况是一项关键任务。本研究在多地点预防无家可归合作项目（CPPH）中，检验了时间线追溯访谈的重测信度、同时效度以及对变化的敏感性。时间线追溯访谈是一种日历工具，用于评估酒精使用的天数和数量以及非法药物使用的天数。时间线追溯访谈在评估过去一个月和最近6个月的使用情况时具有可靠性。时间线追溯访谈的结果与其他使用情况的自我报告、物质使用障碍的研究诊断以及临床医生对物质滥用严重程度的评分相关。时间线追溯访谈检测到了重度精神疾病患者以及精神问题较轻患者的变化。
