Purpose: Premenstrual dysphoria is a mood disorder that occurs at 
certain times of the menstrual cycle. The present study was 
conducted with the aim of the effectiveness of compassion-based 
treatment on emotional ataxia and aggression in women suffering 
from premenstrual dysphoria. 
Materiasl and Methods:The current study is a semi-experimental 
type in which a pre-test-post-test design was conducted with a 
control group with measurement at the baseline after the 
intervention and a 3-month follow-up with the control group. 30 
women aged 25 to 40 diagnosed with premenstrual dysphoria 
referred to psychological counseling centers in Sari in 2019 were 
selected and randomly assigned to the experimental group 
(treatment based on compassion) n=15 and the control group (n=15) 
were assigned. All participants completed the demographic 
questionnaire, emotional non-verbal communication questionnaires 
of Toronto (1994), aggressiveness questionnaires of Bass and Perry 
(1992), in three stages. The intervention sessions were conducted 
face-to-face in compliance with health protocols. Hypotheses 
related to the effectiveness of the research intervention were 
analyzed using multivariate covariance analysis and Lametrics post 
hoc test and using SPSS-19 software.
Findings: The results of the present study showed that there is no 
significant difference between the three groups in the mean of ataxia 
and aggression in the pre-test stage, which indicates the 
homogeneity of the two research groups in the pre-test stage, but 
there is a significant difference between the two groups in the posttest and follow-up stages. Which can indicate the effectiveness of 
the intervention on the mentioned variables and also the stability of 
the effectiveness in the follow-up phase. 
Conclusion: Considering the effectiveness of compassion-based 
treatment, this treatment should be prioritized.
