VALIDATION OF THE INDONESIAN VERSION OF THE PARTNER’S EMOTIONAL DEPENDENCY SCALE (SED): A RASCH MODEL APPROACH

Abstract

This research aimed to verify the Indonesian version of the Partner’s Emotional Dependency Scale (SED), originally developed by Camarillo et al. (2020) in Spanish. The SED is a unidimensional scale with 22 items designed to measure emotional dependence on a partner. This is the first time the instrument has been adapted, particularly for use in Indonesia. The validation process employed the Rasch model to ensure the scale’s reliability and accuracy in the Indonesian context. The study involved 229 participants (F = 185, M = 44), aged between 18 and 35 (MAge = 25.5, SD = 4.23). The results confirmed the unidimensionality of the SED scale, with 2 – 3 items contributing to the second dimension. The 5-point Likert scale functioned effectively, enabling respondents to distinguish between different response options. The person-item interaction reliability was found to be .85, and the item reliability was .98, indicating excellent reliability of the SED scale items. All items were evenly distributed across the scale from high to low difficulty. However, items number 1, 3, and 7 (SED 1, SED 3, SED 7) were identified as less suitable for measuring emotional dependence and respondents found it difficult to answer these specific questions. Furthermore, three items (SED 5, SED 6, and SED 19) exhibited Differential Item Functioning (DIF) due to gender bias. The study concludes that, with some revisions and improving the translation, the Indonesian version of the SED scale could be a valuable tool for measuring the level of emotional dependence on a partner in the Indonesian population.
