To investigate whether substance abuse is a direct factor in the explanation of homelessness or one that operates indirectly through disaffiliation and human capital processes to place individuals at greater risk of the condition.
Analyses were conducted using data on substance abuse and homeless experiences from a random probability sample of 481 homeless persons and those at risk of homelessness in Cook County, Illinois. Covariance structure models were used to assess substance abuse, human capital, and disaffiliation as potential precursors of homelessness, with particular attention paid to the direct and indirect role of substance abuse in the loss of domicile.
Analysis of several nested models of homelessness links substance abuse only indirectly to loss of domicile, primarily through its impact on social and institutional affiliations. Contrary to expectations, substance abuse did not impact homelessness indirectly by diminishing the accumulation of human capital.
The role of disaffiliation as a proximate cause of homelessness was confirmed. This locates the phenomenon within the context of society itself, as a direct result of a breakdown in the social bonds necessary for human community. Substance abuse plays a critical role in this breakdown, negatively influencing social as well as institutional relationships.
调查药物滥用是导致无家可归的直接因素,还是通过脱离社会关系和人力资本过程间接起作用,从而使个体面临更高的无家可归风险。
利用来自伊利诺伊州库克县481名无家可归者及有无家可归风险者的随机概率样本中的药物滥用和无家可归经历数据进行分析。协方差结构模型用于评估药物滥用、人力资本和脱离社会关系作为无家可归潜在先兆的情况,特别关注药物滥用在失去住所方面的直接和间接作用。
对几个嵌套的无家可归模型的分析表明,药物滥用仅通过其对社会和机构关系的影响间接与失去住所相关。与预期相反,药物滥用并未通过减少人力资本积累间接影响无家可归状况。
证实了脱离社会关系是无家可归的直接原因。这将该现象置于社会本身的背景下,是人类社区所需社会纽带破裂的直接结果。药物滥用在这种破裂中起关键作用,对社会和机构关系产生负面影响。
