|---|---|

Sample 1
In Sample 1 (N=186), our 14-item Daily PCS was administered daily for 14 days to replicate the 3-factor structure at the daily level, and to select the ideal 5 items for a brief Daily PCS.

Sample 2
In Sample 2 (N=209), the 5-item Daily PCS was administered daily for 14 days with short forms for PROMIS Pain Intensity, Depression, Anger, and Anxiety included on days 1, 7, and 14.

Sample 3
In Sample 3 (N=318), the 5-item Daily PCS was administered daily for 14 days with short forms for PROMIS Pain Intensity, Depression, Anger, and Anxiety included on days 1, 7, and 14.
In addition, assessments of pain, mood, activity, sleep, energy level, and positive affect were administered daily for the 14-day period.

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. |
