Projection media are valued widely in psychological assessment. However, various pitfalls exist in the administration and interpretation thereof, for instance cross-cultural influences. Seeking to enhance trustworthiness without compromising the projective power of responses, this study investigates the influence of a Dynamic Assessment Technique of Questioning (DATQ) during projective assessments with adolescents in mono- and cross-cultural situations as well as the influence of culture on the emotional assessment situation using DATQ. The main findings suggest a positive influence of DATQ in mono- and cross-cultural assessments regarding projections, projection assessment processes and participants’ emotional experiences, as well as a lowering of cultural barriers. Interview data reveal cultural influences on projected content, suggesting the relevance of a conversation about culture in all cross-cultural assessments for more accurate interpretation of responses. All standardised instructions and procedures should be revisited to control for cultural influences on assessment.
