Considering the importance of assessing nurses' helping relationship skills, it was necessary to use reliable and context-adapted instruments. Thus, the objective of this study was to assess the psychometric properties of the Helping Relationship Skills Inventory (Inventário de Competências Relacionais de Ajuda, ICRA), by conducting reliability and validity studies to increase the level of confidence or accuracy of the data obtained using this instrument. This quantitative study was conducted on a sample of 690 nurses who worked in six hospitals and eight health centres in Portugal. The results indicate a multidimensional structure of helping relationship skills, divided into four different dimensions (generic, empathetic, communication and contact skills) with a positive correlation between them. Cronbach's alpha for each dimension was higher than .79, showing a good internal consistency of the items within each factor.
