Frontiers in Psychology, 15. https://doi.org/10.3389/FPSYG.2024.144432110.3389/FPSYG.2024.1444321https://hdl.handle.net/20.500.14454/2448Introduction: This study is based on the paradigm of collaborative law and the current absence of instruments that evaluate the lawyer-client relationship as a function of the needs of the family system. The objective was to construct and validate an instrument, conceptualizing the lawyer-client relationship as a helping relationship. Method: Two groups of experts and 239 parents (58% mothers and 42% fathers), users of Family Visitation Centers, participated in the study. The content, construct, and criterion validity of the instrument, as well as its invariance for both parents, were analyzed. Results: The resulting 12-item instrument has been shown to have a two-dimensional structure, invariant for both parents, with high psychometric solidity. Discussion: The LCR scale seems to be a valuable and effective measure for use in a legal context, with important correlations with the parents’ psychological well-being, leading to a promising and relevant instrument for the holistic approach to the divorce process.eng© 2024 Martínez-Pampliega, Cormenzana, García-Garnica, Pellón-Elexpuru and MerinoAssessmentCollaborative lawDivorceLawyerParental symptomatologyjournal article2025-03-041664-1078
