Structural equation modeling was utilized to test a hypothesized model for the effects of negative biases, thought suppression, experiential avoidance, and mindfulness on pathological anxiety. Self-report scales were used to measure each construct. Confirmatory factor analyses were used to test the factor structure of each scale. Identified factors were disparate from those in previous research on some scales, so items from scales were pooled to create scales for each construct. Alternate models were tested. No models showed adequate fit. Significant paths between most constructs partially supported our theory. Surprisingly, thought suppression did not predict anxiety. This finding is important because previous literature cites parallels between thought suppression and experiential avoidance to explain the role of experiential avoidance in anxiety. Additionally, the effects of mindfulness on anxiety were mediated by experiential avoidance and negativity bias, providing a possible explanation for the efficacy of mindfulness based treatments for anxiety.
