This study aimed to synthesise recent findings identifying a curvilinear model of Stressful Life Events (SLEs) and a range of good outcomes, with studies finding Psychological Flexibility a more explanatory good outcome underpinning those previously found in this curvilinear model. Participants recruited through social media (n = 298) reporting as Psychologically Flexible and Psychologically Inflexible, as assessed by the Acceptance and Action Questionnaire – II (AAQ-2) were compared in their amount of experienced SLEs at four levels: none, low, medium, and high. This was calculated using the sample mean and spread of data using an adjusted version of the Life Stressor Checklist – Revised (LSC-R). The Big Five Inventory – short (BFI-S) and the Valuing Questionnaire (VQ) were controlled for in a Multiple Hierarchical Logistic Regression. As additional variables were controlled for, medium levels of SLEs remained significant and became more predictive of Psychological Flexibility. Main findings support perspectives that the Yerkes-Dodson Law may be a principle of many facets of human behaviour. Higher VQ scores did not strengthen this relationship, rather, results indicate that AAQ-2 components which may be influenced by SLEs were those pertaining to openness to experience than commitment to values in this analysis. Further, only BFI-S trait Neuroticism significantly predicted Psychological Inflexibility.
