The Effect of Intensive Short-Term Dynamic Psychotherapy (ISTDP) on Increasing the Psychological Well-Being of Patients with Histrionic Personality Disorder (HPD).

Sometimes obstacles and problems arise in a person's life, which disrupts the adaptation and, as a result, the mental balance of the person and causes mental disorders. The aim of the study was to determine the effect of intensive short-term dynamic psychotherapy on the reduction of psychological symptoms in patients with histrionic personality disorder.

The research design was a randomized controlled trial with a pre-test-post-test design and a control group. The statistical population included all adult women living in Semnan with histrionic personality disorder. To collect information, the revised 90-question disease symptom checklist and Riff's psychological well-being scale were used. Descriptive statistics (mean and standard deviation) and inferential statistics (analysis of covariance) and SPSS-26 statistical software were used for data analysis.

Examining the average difference of each of the components of the psychological symptoms of the intervention group (intensive short-term dynamic psychotherapy) and the control group indicates that by removing the effect of the pre-tests, there is a positive relationship between both groups in the components of independence, self-mastery, personal growth, With others, there is a significant difference in purpose in life, self-acceptance and psychological well-being.

The obtained results show that psychodynamic therapy allows the expression of emotions caused by stress in a safe environment with no feeling of rejection by the therapist, which leads to the growth of these people. Shedler (2010) believes that short-term intensive psychodynamic therapy, in addition to high insight and meaningful effectiveness, leads to long-term improvement of clients. This method, through a corrective emotional experience, makes a person in a suitable environment have the opportunity to face what he has avoided throughout his life and the non-adaptive ways he used to communicate with himself and others (one of the components of psychological well-being). let g
