Detecting Change in Needs-Supplies Fit Through Reliable Change Methodology.

Studying change is a critical part of psychology and science in general. Studies often treat fit as static and use between-person designs to assess change. Accordingly, potentially insightful within-person information is frequently overlooked. The current study aimed to establish the utility of reliable change methodology within the domain of organizational psychology, using needs-supplies fit as a guiding framework. When employee needs can be tracked with a fair degree of clarity, organizations can devise better strategies to routinely address discrepancies between desired employee needs and organizational offerings. This longitudinal study used secondary data from 258 secondary school teachers. The Needs-Supplies Fit Scale was administered. The study's hypothesis was assessed through reliable change methodology. When considering all the participants that experienced at least some change across time intervals (n = 148), 23.65% (n = 35) of this change was meaningful. This declined to 17.33% meaningful change when factoring in the entire sample, including those who did not experience any change. When organizations are aware of the ever-evolving needs of employees, quicker action can be taken to avoid impending person-environment misfit. This study contributes to existing within-person studies that showcased the malleability of needs-supplies fit and emphasize the value of placing a more prominent focus on the individual.
