We inspected the distributions of number of pain sites; scores on the SES, GDS, pain intensity, and pain interference measures; strategy helpfulness scores for strategies used by 25% or more participants (to ensure an adequate subgroup size); and number of treatments used; none were substantially skewed (i.e., skewness > 1.0).
The results of the one-way ANOVA for the FSS-7 interference measures revealed a significant main effect for diagnostic group (F [19.81] p < 0.001).
Stroop Colour Word Interference Test scores were calculated as the time difference for completion of the interference measures minus the non-interference tasks; attention/psychomotor speed as absolute times on the Stroop 1 and 2 subtests (Stroop, 1935).
However, existing work has the following limitations: (1) the energy model adopted is quite unrealistic — only transmit power is often considered and homogeneous decay of the radio signal with distance is assumed; (2) the interference measure does not account for multi-hop communications.
This finding might imply that the BPI interference scale measures are partly responded to as more of a global interference measure.
As a secondary endpoint, daily sleep interference scores were measured for all study participants by assessing the degree to which pain interfered with sleep during the previous 24 hours on an 11-point numerical rating scale.
The present analysis focuses on the number of days out of the last 30 that physical health was not good and analogous measures for mental health, interference of health with activities, and pain.
Lifestyle interference: assessment tools, time points and outcomes measures for caregivers for quantitative studies.
HRQOL measures included the number of days out of the last 30 that physical health was not good and analogous measures for mental health, pain, and interference with activities, as well as a composite "healthy days" measure developed by CDC.
Nevertheless, we assume the expected interference as a suitable measure for obtaining frequency assignments.
