Note. DV indicates the dependent variable for the model. Means and within-person variance in negative emotions were regressed on Pain Intensity, Pain Interference and Downtime (Rest) in separate models. Model parameters for Pain Intensity, Pain Interference, and Downtime predicting within-person variance are bolded for ease of interpretation.
