The sample size was 25 participants selected using a purposive sampling technique. Data were collected using a bullying knowledge questionnaire and statistically analyzed using the Wilcoxon Signed Rank Test.

The statistical test results showed a p-value of 0.000 < 0.05, indicating that psychoeducation through Google Sites was effective in increasing knowledge about bullying among junior high school adolescents.
