Factors Influencing the Choice and Retention of Engineers as Adjunct Professors in Higher Education Institutions

Abstract

Abstract– This study examines the factors influencing the choice and retention of engineers as adjunct professors in a Dominican multicampus university (n=150). Using a cross-sectional quantitative design grounded in Self-Determination Theory (SDT), the Job Demands–Resources (JD-R) model, and organizational justice theory, validated composite indices were constructed for intrinsic and extrinsic motivation, positive and negative emotions, professional contribution, institutional satisfaction, and institutional difficulties. Results show that intrinsic motivation predominates over extrinsic (M=4.26 vs. 3.19; p<.001, r=0.776), and that negative emotions are the strongest predictor of turnover intent (ρ=+0.421, p<.001). Experiencing a critical breaking point multiplies the probability of not continuing fivefold (OR=4.86, p=.004). Institutional communication and collegial climate are the top-rated facilitators; pay equity and assignment stability are the main obstacles.
