psychometric properties of the persian version of the early life experiences scale (eles)

Background: early relationships with parents and their influence on the development of psychopathology have been a topic of interest from different theoretical approaches. early-life experiences have long-term distributive effects on children’s psychological and behavioral development. objectives: the present study aimed to determine the validity and reliability of the early life experiences scale (eles). methods: for developing the persian version of the eles, the original scale was translated, reconciled, and back-translated. a sample of 231 students from iran university of medical sciences selected by convenience sampling method in 2019 - 2020 responded to the questionnaires, namely the eles, difficulties in emotion regulation scale (ders), schizotypal trait questionnaire-b form (stb), and self-compassion scale (scs) short-form. the construct validity of the eles was determined via confirmatory factor analysis and divergent and convergent validity. internal consistency and test-retest reliability (two-week interval) were applied to evaluate the reliability. data analysis was performed using lisrel (version 8.80) and ssps (version 20) software. results: the results showed that the eles is a reliable and valid tool with good internal consistency and test-retest reliability (> 0.70). concerning convergent validity, eles showed a significant positive correlation with ders (r = 0.26) and stb (r = 0.37). it also showed a significant negative relationship with self-compassion (r = 0.45), which indicates the desired divergent validity. the results support the three-factor structure of this scale (submissiveness, feeling valued/unvalued, and feeling threatened) (comparative fit index (cfi): 0.96, normed fit index (nfi): 0.95, root mean square error of approximation (rmsea): 0.08). conclusions: the early life experiences scale showed adequate validity and reliability and can be applied in evaluating early life experiences in the iranian population.
