Penilaian uji validitas isi dilakukan melalui penilaian face validity melalui focus group discussion dan penilaian SCVI/Ave yang melibatkan 5 pakar. Uji validitas CFA menggunakan parameter dengan estimator ULS melalui aplikasi JASP for Mac dan uji reliabilitas menggunakan penilaian Cronbach Alpha melalui software SPSS. Hasil: Nilai CVR 0,6 terdapat pada satu item, yaitu item nomor 28 sehingga modifikasi tatanan Bahasa untuk merevisi item ini. Nilai S-CVI/Ave sebesar 0,9. Hasil analisis CFA didapati Chi-square p > 0,05. Indeks kesesuaian model CFI sebesar 0,982, TLI sebesar 0,979, RMSEA sebesar 0,062 dan SRMR sebesar 0,059. Penilaian reliabilitas mendapatkan nilai total Cronbach’s alpha sebesar 0,944. Karakteristik demografi dan pola penggunaan bervariasi berdasarkan jenis kelamin serta persepsi kecanduan subjektif.

The impact of online shopping addiction includes economic problems, legal problems, social problems and a decrease in the overall quality of life for the individual him/herself, family, and those around theirs. However, the availability of early detection instruments for online shopping addiction has not yet exist in Indonesia. Therefore, a validity and reliability test of the Indonesian version of the Compulsive Online Shopping Scale (COSS), as one of the self-report instruments, is needed to produce a valid and reliable early detection instrument for online shopping addiction.

The pilot trial involved 20 adult subjects and the field test involved 319 adult subjects. The assessment of the content validity test was carried out through a face validity assessment through a focus group discussion and an S-CVI/Ave assessment involving 5 experts. The CFA validity test uses parameters with the ULS estimator through the JASP for Mac application and the reliability test uses the Cronbach Alpha assessment through SPSS software Results: The CVR value of 0.6 is found in one item, item number 28, so the modification of the language order is to revise this item. The S-CVI/Ave value is 0.9. The results of the CFA analysis found Chi-square p> 0.05. Model fit index CFI is 0.982, TLI is 0.979, RMSEA is 0.062 and SRMR is 0.059. The reliability assessment obtained a total Cronbach's alpha value of 0.944. Demographic characteristics and patterns of usage vary by gender and the subjective perception of addiction. Conclusion: The Indonesian version of the COSS instrument is valid and reliable because it has good content validity test results, construct validity tests and reliability tests. There are differences in preferences, highest domain of online shopping behavior in men and women which are based on biopsychosocial factors.
