This article provides a brief introduction to the Repertory Grid Technique and aims to demonstrate the use of the technique in different social work contexts. The Repertory Grid Technique draws from an open interview procedure that requires respondents to classify and evaluate elements within the environment on a numerical scale according to their own personal constructs. The result of this interview is a cognitive matrix of elements and constructs that can be explored in both a qualitative and a quantitative manner. Several applications for the practice, education and research of social work are suggested, with the overall purpose to heighten the perception of individuals' mental construction of their social life.
