*2.4. Data Analysis*

Quantitative data were analyzed with SPSS 23.0 (IBM Corp. Released, Armonk, NY, USA). We used the non-parametric Mann-Whitney U test and Friedman test for analyses. Qualitative data were sorted based on the Kawakita Jiro (KJ) method which is used to organize data into useful categories. It adopts the bottom-up sorting process and is very useful for classifying data. Based on the statement of significance of "Change after group counseling", researchers summarized, coded and recorded responses with concise, independent and clear phrases, extracted representative topics, and formed a comprehensive database of self-reported parsed statements from group members.
