Researchers recruited the participants between September 2022 and March 2023 using convenience sampling. The sample consisted mainly of female and undergraduate students. Psychological flexibility, neuroticism, and subjective well-being were assessed with validated self-report measures.

The investigators used correlation and regression analyses to examine relationships among the variables, latent profile analysis to identify psychological flexibility profiles, and mediation analysis to assess the indirect association through neuroticism. The latent profile analysis classified 44.2% of participants as having moderate psychological flexibility, 29.6% as having high psychological flexibility, and 26.2% as psychologically inflexible. Subjective well-being differed significantly across these three profiles.

The high-flexibility group had the highest scores, and the psychologically inflexible group had the lowest. These are statistical associations observed within the study sample and do not demonstrate that psychological flexibility caused the differences in well-being. The mediation analysis found that neuroticism carried a statistically significant indirect association between psychological flexibility and subjective well-being.

The result does not show that changing neuroticism would change a student’s well-being, nor does it establish a clinical effect. The authors said the findings support the need for psychological support for students with low psychological flexibility, while the use of convenience sampling and self-report measures limits how broadly the results can be generalized.
