Neighborhood disorder, sleep quality, and psychological distress: Testing a model of structural amplification

Using data from the 2004 Survey of Texas Adults (n=1504), we examine the association between perceived neighborhood disorder and psychological distress. Building on previous research, we test whether the effect of neighborhood disorder is mediated and moderated by sleep quality. Our specific analytic strategy follows a two-stage theoretical model of structural amplification. In the first stage, perceptions of neighborhood disorder increase psychological distress indirectly by reducing sleep quality. In the second stage, the effect of neighborhood disorder on psychological distress is amplified by poor sleep quality. The results of our analyses are generally consistent with our theoretical model. We find that neighborhood disorder is associated with poorer sleep quality and greater psychological distress. We also observe that the positive association between neighborhood disorder and psychological distress is mediated (partially) and moderated (amplified) by poor sleep quality.
