The present study aimed to determine the fit of the predictive model of suicidal ideation based on early maladaptive schemas mediated by difficulty in emotion regulation in teachers. This study is an applied study in terms of its purpose and a descriptive correlational study in terms of its method, which was conducted using structural equation modeling. The statistical population consists of all teachers working in schools in Tehran during the spring of 2025, from which 320 people were selected using the available sampling method. The research instruments included the Beck Scale for Suicide Ideation (1979); the Emotion Regulation Difficulties Scale by Gratz & Roemer (2004) and the Young Schema Questionnaire-short form (1998). Data analysis was performed using structural equation modeling. The results showed that the predictive model of suicidal ideation based on early maladaptive schemas mediated by difficulty in emotion regulation in teachers fits the collected data. Suicidal ideation is predicted based on early maladaptive schemas in teachers (P=0.001, β=0.400). Suicidal ideation is predicted based on difficulty in emotion regulation in teachers (P=0.001, β=0.378).
