About this study

The Pain Catastrophizing Scale (PCS; 13 items; factors: rumination, helplessness, magnification) (Sullivan 1995) measures trait catastrophizing in the context of actual or anticipated pain. Currently, there is no validated tool for measuring pain catastrophizing at the daily level. Lack of a validated daily measure stands as a barrier for studies that aim to characterize mechanisms of pain treatment and how PC adaptation / change occurs.

Primary outcomes

  1. Factor Analysis & PROMIS Correlation for Samples 2 & 3

    Time frame: 14 days

    The validation process involves identifying, of the original 14 PCS items, which items show the largest factor loadings to the underlying factor structure that fits the data best, using model fit indices that will determine appropriate fit of the statistical model to the data, as well as convergent validity with other relevant measures (pain intensity, depression, anxiety, anger), which is tested through the use of Pearson correlations.

    Metrics used to test the hypothesis: Intraclass correlations were used to establish variability. RMSEA, CFI, TLI, and WRMR as our goodness of fit indices for arriving at 3- and 5-item measures, and to compare the measures. Reliability was tested using α. Correlations between daily pain, mood, activity, sleep, and energy were tested using pearson coefficients.

    Intent was to measure correlations between the brief PCS and the PROMIS for validation sample 2, and correlations between the brief PCS and the PROMIS for validation sample 3.
