Analysis was carried out in SPSS to determine before (Pre) and after (Post) treatment of participants from the two groups, that is, level of anxiety among children who between 3 to 13 years and adult opiate substance abuse for adults aged 65 and above.

Wilcoxon Signed Rank test was used to examine Spence Children's Anxiety Scale (SCAS) outcome variables for the levels of anxiety between children of ages 3 to 13 (Reardon et al., 2018). The variables SCAS_Pre_Total and SCAS_Pst_Total, which were the sums of score items before and after treatment, were used. Analysis was as shown in Table 1.

Table 1

According to the analysis, Z (52) = -.962, p = .336. The descriptive statistics showed that children anxiety was higher after treatment (M = 67.76, SD = 9.29) compared to before treatment (M = 67.64, SD = 9.50). The difference was not significant however since the p-value was greater than .05.

Wilcoxon Singed Rank Test was also used to examine the difference in mean scores for adult opiate substance abuse (ASI) before and after treatment. Table 2 showed the results of the analysis.

Table 2

Analysis indicated that Z (44) = -3.584, p < .01. According to descriptive statistics, the ASI scores after treatment were higher (M = 27.67, SD = 6.45) compared to ASI scores before treatment (M = 27.67, SD = 6.45). The differences in opiate substance abuse among older people showed that treatment significantly increased the intake since p-value was less than .05 level of significance.

When a control and treatment group are considered, Mann-Whitney U test was the most suitable test to determine the difference in means for SCAS and ASI scores between those who received treatment and those who did not (Lin et al., 2021). The analysis were as shown in Table 3.

Table 3

Analysis indicated that the difference was not significant for both SCAS_Pre_Total (Z (52) = -.565, p = .572) and SCAS_Pst_Total (Z (52) = -.582, p = .561).

Table 4 shows the Mann-Whitney U test for the opiate substance abuse scores.

Table 4

Analysis indicated insignificance difference in means between treatment and control group for both ASI_Pre_Total (Z (44) = -.746, p = .456) and ASI_Pst_Total (Z (44) = -1.48, p = .139).
