The random allocation sequence will be generated by an independent statistician using a computer-based random number table (Excel or SPSS). To ensure allocation concealment, the randomization sequence will be kept in sequentially numbered, opaque, sealed envelopes (SNOSE). After verifying inclusion and exclusion criteria and obtaining informed consent, the corresponding envelope will be opened, and the participant will be assigned to the designated group. The outcome assessor will be blinded to group allocation. N/A breast cancer. Intervention 1: Control group: The control group received only standard medical care during the study period and did not receive any group or individual psychotherapy intervention.

The research tools included the Life Expectancy Questionnaire (BHI), the Behavioral Regulation Questionnaire (BRI), and the data were analyzed using independent and paired t-tests and Pearson correlation coefficient. The findings showed that after the intervention, the experimental group had a significant improvement in all variables compared to the control group.
