In this study, we examined associations between university lecturers' perceived autonomy support (PAS), adaptability, organisational commitment, and psychological wellbeing. A sample of university lecturers (N = 102) from a single ex-polytechnic higher education institution in the United Kingdom completed validated scales for each construct in the spring term. Inspired by prior work in pre-tertiary education with schoolteachers, a conceptual model of predicted relations was developed and tested using structural equation modelling (SEM). Findings showed that PAS was positively associated with lecturers' adaptability, organisational commitment, and psychological wellbeing; however, adaptability was unable to influence these outcomes independently of its association with PAS. The findings extend prior work with schoolteachers suggesting that, while adaptability is of importance, its influence may be more salient at pre-tertiary level-where there is typically heightened regulation and lower autonomy-and less salient when autonomy options are wider, as is the case in higher education.
