does not give good accuracy only 0.58. Log-rank test showed that the variables attitude, problem Prayer,
interaction history and treatment reactions had different survival curves between the categories of each
variable. The interaction history variable does not meet the proportional hazard assumption so that the Cox
model used is stratified and time-dependent Cox. The best model is the Cox stratified model with the
interaction having the smallest AIC value of 286.84. Factors that have a significant effect on the time to
improve mental conditions are gender and the main complaint in the patient strata who have a history of
interaction and the age variable in the stratum of patients who have had a history of interaction.
