7/23/2012
This document is private and confidential. It contains two statistical analyses of the data at intake and
then both 6 months and 12 months. Frequencies, descriptive statistics and repeated measures t-tests
are included. Additionally, the report contains graphical analyses using SPSS and statistical
interpretations.
Pain Outcomes Questionnaire Statistical Analysis
Research Question: will the implementation of TCC’s coaching program affect those suffering with
chronic pain using the Pain Outcomes Questionnaire as the measurement system.
Null hypothesis: Implementation of the coaching program will not affect the total scores on the POQ
Alternative hypothesis: Implementation of the coaching program will affect the total scores on the
POQ.
Method: Data was collected using the POQ. Measurements were taken before the coaching began with
a total of 14 participants from intake to 6 month follow up and13 participants from intake to 12 months.
Data from the POQ was entered into SPSS software. Descriptive statistics, frequencies and repeated
measure t-tests were performed on both sets of data. Frequency data was performed on the entire
data set (n = 14).

A paired-sample t test was conducted to evaluate whether there was a reduction in scores on the POQ
upon completing 6 months of coaching. The results indicated that there was a significant change in
the POQ scores from with the POQ scores at 6 months (M = 42.6 , SD = 23.5), t(13) = 6.8, p < .000. The
95% confidence interval for the mean difference between the two ratings resulted in a reduction of 42
points on the POQ. Additionally, 7 of the 8 of the subscales were statistically significant which
included Pain (p < .000), Mobility (p < .000), Activities of Daily Living (p < .000),Vitality (p < .000),
Negative Affect (p < .000) and Fear (p < .000). Healthcare Visits was not statistically significant (p<
.147)
Using the rating scale from the outpatient POQ, these results can be interpreted as follows: After 6
months of coaching, the total scores on the POQ dropped from the 50-74% range of pain to 10-24%
range.
From a preliminary data analysis it was also noted that all the mean scores for all the subscales
decreased.

Intake to 12 Months Data Analysis
A paired-sample t test was conducted to evaluate whether there was a reduction in scores on the POQ
upon completing 12 months of coaching. The results indicated that there was a significant change in
the POQ scores from intake to 12 months (M = 29.8, SD = 17.8 ), t(12) = 9.4, p < .001. The 95%
confidence interval for the mean difference between the two ratings resulted in a reduction of 59
points on the POQ. Additionally, all 7 subscales were statistically significant which included Health
Care Visits (p < .02), Pain (p < .00), Mobility (p < .00), Vitality (p < .00), Negative Affect (p < .01) and
Fear (p < .00).
Using the rating scale from the outpatient POQ, these results can be interpreted as follows: After 12
months of coaching, the total scores on the POQ dropped from the 50-74% range of pain to 10-24%
range.
From a preliminary data analysis it was also noted that all the mean scores for all the subscales
decreased.
