“…Therefore, studies need to be made with other samples from other Arabic-speaking countries to replicate the findings and determine which ones are valid. Nevertheless, the findings of this research do not differ from those of other studies using different versions of the FPS-R in samples with different languages [ 8 , 24 , 26 , 46 , 47 ]. Second, the nature of the procedure that requires imagination might have affected the results since some of the children might not have experienced burning their hand; yet, the procedure was used as it had been in several previous studies [ 48 , 49 ].…”

The Faces Pain Scale-Revised (FPS-R) is widely used to assess pain intensity in young people. The aims of this research were to study the convergent and discriminant validity and reliability properties of a culturally adapted version of the FPS-R for its use with Arabic-speaking individuals. The sample consisted of 292 students living in Lebanon. They were interviewed online, asked to imagine themselves in one of two given situations based on their age (8–12 and 13–18 years old), and then asked rate the intensity of pain they would experience using the FPS-R-Arabic and a Numerical Rating Scale (NRS-11-Arabic). They were also asked to respond to the Pain Catastrophizing Scale (PCS-C-Arabic). Two weeks later, participants were asked to repeat the same procedure. The data showed strong associations between the scores of the FPS-R-Arabic and NRS-11-Arabic (r = 0.72; p < 0.001), which were higher than the associations of the scores of the FPS-Arabic with the PCS-C-Arabic scores (z = 7.36, p < 0.001). The associations between the FPS-R-Arabic scores on the two measurements were also strong (r = 0.76; p < 0.001). The findings support the convergent and discriminant validity and reliability of the FPS-R-Arabic scores when used to measure pain intensity in young people aged 8 to 18 years old.

To assess postoperative pain intensity in adults, the numeric rating scale (NRS) is used. This scale has shown acceptable psychometric features, although its scale properties need further examination. We aimed to evaluate scale properties of the NRS using an item response theory (IRT) approach. Data from an international postoperative pain registry (QUIPS) was analyzed retrospectively. Overall, 346,892 adult patients (age groups: 18-20 years: 1.6%, 21-30 years: 6.7%, 31-40 years: 8.3%, 41-50 years: 13.2%, 51-60 years: 17.1%, 61-70 years: 17.3%, 71-80 years: 16.4%, 81-90 years: 3.9%, >90: 0.2%) were included. Among the patients, 55.7% are female and 38% had preoperative pain. Three pain items (movement pain, worst pain, least pain) were analyzed using 4 different IRT models: partial credit model (PCM), generalized partial credit model (GPCM), rating scale model (RSM), and graded response model (GRM). Fit indices were compared to decide the best fitting model (lower fit indices indicate a better model fit). Subgroup analyses were done for sex and age groups. After collapsing the highest and the second highest response category, the GRM outperformed other models (lowest Bayesian information criterion) in all subgroups. Overlapping categories were found in category boundary curves for worst and minimum pain and particularly for higher pain ratings. Response category widths differed depending on pain intensity. For female, male, and age groups, similar results were obtained. Response categories on the NRS are ordered but have different widths. The interval scale properties of the NRS should be questioned. In dealing with missing linearity in pain intensity ratings using the NRS, IRT methods may be helpful.

“…A Rasch measurement analysis could add to this body of evidence statistically by fixing the discrimination parameter equal across all items and assessing the extent to which the category difficulty parameters should be held constant across items (RSM) or freely estimated across items (PCM). Furthermore, with the ability to test the better fitting polytomous Rasch model (i.e., RSM vs. PCM), one can assess the extent to which the MSAS scale should be considered an interval-level (RSM) or ordinal-level (PCM) scale [36]. Secondly, an experimental study on the MSAS is suggested to further evaluate its ability to separate MSA participants with known trait differences.…”

Background: With the growing need to promote muscle strengthening activity (MSA) for improved health-related quality of life (HRQOL) comes the growing need for proper measurement of MSA behavior. The purpose of this study was to examine test and item functioning of the MSA scale (MSAS) using item response theory (IRT). Methods: The current research fit data from a sample of N = 400 respondents to two different graded response models (GRMs), a three-item muscular strength scale and a three-item muscular endurance scale. For each GRM, model-data fit was examined and IRT assumptions assessed. Results: An unconstrained GRM was found to fit the data better than the constrained model (Δ G 2 Strength = 10.3, p = .006, RMSEA = .043 & Δ G 2 Endurance = 7.0, p = .031, RMSEA = .021). GRM boundary location parameters covered the latent trait scale well for both strength (bs: -4.26 to 2.58) and endurance (bs: -3.86 to 1.79) scales with each item showing adequate fit to the data (all RMSEAs < .05). Test information was approximately evenly distributed around a theta of zero with summed information from theta ranges ±4 of 92.8 (strength) and 93.5% (endurance). Only 2.3 and 1.5% of persons misfit the strength and endurance GRMs, respectively. Conclusion: The MSAS has shown to be a valid tool for measuring MSA behavior in adults using modern psychometric theory.

Abstract: According to these findings, the interval scale properties of the FPS-r may be questioned. Item response theory methods may help to solve the problem of missing linearity in pain intensity ratings using FPS-r.
