convergent validity was measured by comparing the Turkish version of SF-MPQ responses with the results of the NRS. SF-MPQ Discriminant construct validity was determined by Pearson’s ICC 95% CI correlations with the patient’s blood pressure values. A
probability value of p < 0Æ05 was considered to indicate a significant effect.
Results
Sample characteristics
The mean age of the patients with leukaemia who participated in the research was 53Æ42 ± 8Æ59 years. Of the patients 57Æ7% were women and 42Æ3% men; 37Æ5% of them were
primary school graduates (Table 1).
Reliability analysis
According to the Wilcoxon’s signed-rank test, there was no difference between test and retest values of the total, sensory, affective, ETPI and VAS scores (p > 0Æ05). Internal consistency was found adequate at both assessments with Cronbach’s a 0Æ88 for test and 0Æ91 for retest. Test–retest reliability was found to be ICC = 0Æ85 for total score, 0Æ84
for sensory score, 0Æ82 for affective score and 0Æ70 for ETPI score. The test–retest reliability for the VAS of SF-MPQ was found to be 0Æ64 (Table 2).
Validity analysis
Correlation between the total, sensory and affective scores of the Turkish version of the SF-MPQ and the NRS was tested for construct validity. The resulting correlation was r = 0Æ61 (p < 0Æ01) for test and r = 0Æ68 (p < 0Æ01) for retest, demonstrating moderate correlation. For concurrent validity, the Table 1 Demographic characteristics of the subjects (n = 130)
