Abstract

Objective: Personality traits can affect humans' mental health. In the present study, we aimed to assess the relation of loneliness to personality traits and also to inequality in socio-economic status in girl students. Methods: In a cross-sectional study, investigated the relations of personality traits to loneliness in girl students in Ilam from 2014 to 2015. A multistage cluster random sampling method was used to select the participants. The NEO-FFI and University of California, and Los Angeles questionnaires were used for data collection. Data were analyzed by IBM SPSS and Distributive Analysis Stata Package (DASP). Results: Among 400 recruited participants, 149 (37.2) were categorized as having loneliness. The concentration index (CI) for loneliness was 0.19 (95 confidence interval CI] 0.07, 0.27), which indicated that loneliness was observed more in persons with high socioeconomic status. The risk of loneliness was 38 lower in persons with higher scores in neuroticism (adjusted odds ratio (AOR) = 0.62, 95 CI: 0.48, 0.91). Conclusion: We found that socio-economic inequality was observed in relation to loneliness with girls of higher socioeconomic status reporting more loneliness. Therefore, more attention should be directed by policymakers to determining the main contributors to inequality contributors and loneliness in advantaged societies.
