The Intercultural Development Inventory® (IDI®) a theory-based, developmental psychometric instrument grounded in a comprehensive, cross-culturally validated theory of intercultural competence – the Intercultural Development Continuum.
The IDI is a psychometric instrument based on the Intercultural Development Continuum (IDC). As an assessment tool, the IDI measures an individual's or group's progression along a developmental path of increasing complexity in making sense of and responding to cultural differences. The IDI measures both one’s mindset and skillset which allows individuals and groups to better understand successes and challenges related to their intercultural interactions.
The IDI is a developmental assessment of intercultural competence which empowers individuals and groups to increase their effectiveness in how they engage cultural differences. This focus on development can be used to facilitate cooperative conversations and actions directed toward growth rather than judgment and resistance.
The IDI provides in-depth insights on individuals’ and group’s levels of intercultural competence. This is accomplished through customized IDI Individual Profile Reports and IDI Group Profile Reports, which present valid quantitative and qualitative information about how individuals and groups engage cultural difference in their day-to-day interactions with others.
The IDI provides quantitative and qualitative data to support and guide developmentally appropriate actions for individuals and groups. IDI Group Profile results can be used to inform and shape the focus of developmental opportunities for teams, departments, and organizations. For individuals, a customized self-directed Intercultural Development Plan (IDP) guides them through a series of developmentally appropriate activities and self-reflections to increase their intercultural capability.
The IDI is descriptive of mindsets toward making sense of and responding to cultural differences both generally and within particular cultural or group contexts. This means that, regardless of the individual’s or group’s cultural background, the IDI assesses how cultural differences are thought of and navigated. Because of this, the IDI can be used with all individuals and groups, regardless of their cultural background.
The IDI can be used to provide feedback and developmentally appropriate recommendations for both individuals and groups. It can also be used for baseline assessments and organizational development, or as a pre-post assessment in program evaluation. The IDI is also used in various research applications.
This means the IDI a well-designed assessment tool that has been rigorously tested and proven to be valid, reliable, and applicable across different cultures and contexts. It can effectively measure an individual's or group's intercultural competence regardless of their cultural background or setting. In other words, the IDI is a trustworthy and consistent way to evaluate how well someone can navigate and engage with diverse cultures in a way that is meaningful and effective.
Due to available resources, IDI projects may be implemented in phases; for example, certain groups or teams may be invited to complete the IDI first, followed by other teams. Resources may also be allocated further by having individuals opt in to attend an Individual Debrief to receive their Individual Profile Report and Intercultural Development Plan (IDP).
