The Relationship Between Loneliness and Personality Traits and Rumination with Suicidal Thoughts in Adolescent Girls

Abstract

The present study aimed to investigate the relationship between loneliness, personality traits, and rumination with suicidal thoughts in adolescent girls in Karaj. This was a descriptive-correlational study. The statistical population included all female high school students in Alzahra, Hejab, and Razieh schools in District 1 of Karaj during the 2022-2023 academic year. A sample of 168 students was selected using convenience sampling. The research instruments included Beck Scale for Suicidal Ideation (1974), Russell’s Loneliness Questionnaire (1980), HEXACO Personality Inventory (2000), and Nolen-Hoeksema & Morrow’s Rumination Questionnaire (1991). Data were analyzed using Pearson correlation coefficient and simultaneous multiple regression analysis. The results indicated a significant positive relationship between loneliness (p<0.01), high emotionality personality factor (p<0.05), and rumination (p<0.01) with suicidal thoughts. Moreover, a significant negative relationship was found between extraversion, openness to experience, agreeableness, and conscientiousness with suicidal thoughts (p<0.01). Regression analysis showed that loneliness, personality traits, and rumination altogether predicted approximately 38% (R^2=0.388) of the variance in suicidal thoughts. Loneliness, emotionality personality trait, and rumination play an effective role in the formation of suicidal thoughts in adolescent girls; therefore, considering these factors is essential for prevention and therapeutic interventions.
