Psychometric Properties of the Greek Inventory of the Dimensions of Emerging Adulthood (IDEA): University Student Perceptions of Developmental Features

Emerging adulthood, the transitional period from adolescence to adulthood, differs demographically and is associated with the cultural and socioeconomical environment one lives in. Its key dimensions have been explored in many countries including the USA through the IDEA instrument (Reifman et al. in J Youth Dev 2(1):1-12, 2007). Five dimensions have been identified and associated with specific items. In this paper, we aim to measure the psychometric properties of the IDEA used to measure key developmental features associated with emerging adulthood in Greece. A total of 592 University Humanity and Science students, both male (29.3 %) and female (70.7 %), aged 18-30 years were asked to complete a questionnaire battery including the IDEA and a set of demographic questions. We used structural equation modeling to identify factors underlying the IDEA. We identified three factors, which we named "Identity exploration/Feeling in-between," "Experimentation/Possibilities/Self-focused" and "Negativity/Instability." The first two factors appeared to be more prominent in our sample, while evidence of negativity and instability was limited among the study participants. Further analyses assessed the impact of demographic characteristics of participants on the above three factors. Age, gender and type of studies appeared to exert some influence on the perception of main features of emerging adulthood. Further research linking the criteria to the developmental features characterizing this distinct age group is required in order to unveil the intricacies of the phenomena of emerging adulthood in Greece.
