Psychometric properties of the dependent ideation scale

Abstract Dependent ideation is based on (patriarchal) gender mandates and romantic love ideals leading to the idea that a partner is absolutely necessary in a person’s life; this attitude is associated with fear of being single, abnegation, and difficulty receiving affection. Method: The construction of the scale used a sequential derivate method including a first phase focused on content validity followed by a transversal design approach for exploratory factor analysis and confirmatory factor analysis (CFA) with a different population sample. Finally, using the same design, convergent and discriminant validity correlations between two different measurement instruments were obtained. The total sample included 617 participants from the state of San Luis Potosí (center) and the city of Tijuana (northern border), both in Mexico. Results: Content validity was determined using Kendall’s W with an average of .272, as well as Aiken’s V, with an average of .905. CFA indicated a composite reliability > .75 for all factors, AVE > .50 and MSV < .209. Therefore, the instrument’s reliability and validity properties were found to be adequate to measure dependent ideation. Additionally, remarkable criterion, convergent, and discriminant validity values were obtained.
