Spss statistic software version 27

Data were analyzed using IBM SPSS statistic software version 27. All data underwent Kolmogorov-Smirnov analysis for normality of distribution. Continuous variables are described as means ± standard deviation. Parametric and nonparametric ANOVA (Kruskal-Wallis analysis) of variance with corrected post-hoc Bonferroni tests were used to evaluate the effect of experimental condition (T1/T2) and of group (ON/OFF) on pain ratings. Effects size of post-hoc comparisons were evaluated with Cohen’s d. Differences in the outcome measures between T1 and T2 conditions (delta) were calculated by subtracting the former from the latter. Correlations between pairs of variables were calculated with Pearson’s r; p < 0.05 was considered significant. The Bonferroni correction was applied to multiple comparisons, where needed.

The statistical analysis was performed by ANOVA 1-factor with a Games–Howell post-hoc test, using IBM SPSS statistic software (version 27). The statistical significance was set at 0.05 (p < 0.05).

The internal consistency of the material security scale that demonstrated the extent to which items were measuring the same construct was assessed using Cronbach’s alpha coefficient. A Cronbach’s alpha of 0.7 was deemed acceptable. The analysis of the revised material security scale, based on the final model, was performed using IBM SPSS Statistic software version 27 (SPSS Inc., Chicago, IL, USA).
