Cognitive Fusion, Ruminative Response Style and Depressive Spectrum Symptoms in a Sample of University Students.

Psychological inflexibility is related to depressive symptoms through the 'ruminative response style' (RR) and 'cognitive fusion' (CF). We aimed at exploring whether university students were more exposed to CF, RR and depressive symptoms because of their intellectual performance than non-university students of the same age. We compared university students (US) ( = 105) vs. non-university students (NUS) ( = 76) through online administration of the 'Cognitive Fusion Questionnaire' (CFQ-7), the 'Depression-Zung Self-Assessment Scale' (ZSDS) and the 'Perseverative Thinking Questionnaire' (PTQ) (study protocol #0077818/2022, approved by the Ethical Committee of the University of Pisa, Italy). University students scored significantly higher than non-university students in the CFQ-7 Total Score (27.5 ± 9.4 vs. 24.4 ± 9.5; = 0.040), ZSDS Total Score (41.1 ± 7.7 vs. 39.0 ± 7.3; = 0.031), PTQ Total Score (26.1 ± 13.1 vs. 21.8 ± 13.9; = 0.029), PTQ 'Repetitiveness' (5.3 ± 2.8 vs. 4.5 ± 2.9; = 0.034), 'Intrusiveness' (5.8 ± 3.0 vs. 4.8 ± 3.1; = 0.046) and 'Repetitive Negative Thinking capturing mental resources' (5.0 ± 3.1 vs. 4.0 ± 3.0; = 0.013) (MANOVA analysis). In a binary logistic regression analysis of US (with ZSDS scores < 44 vs. ≥44 as the dependent variable, and PTQ Total Score and dimensions, CFQ-7 Total Score, age and gender as the covariates), PTQ Total Score predicted the more severe depressive symptomatology (OR = 1.44, 95% CI: 1.017-2.039; = 0.040). We believe that RR and CF should be specifically targeted through psychoeducational/psychotherapeutic interventions in university students.
