Alexithymia is a trait characterized by compromised emotion processing. It represents a key risk factor for various psychopathologies, yet its underlying mechanisms remain unclear. According to the attention-appraisal model, one mechanism is experiential avoidance, a tendency to avoid aversive emotional experiences. To investigate this proposed relationship, participants (N = 444) completed questionnaires assessing alexithymia, experiential avoidance, and various psychopathology symptoms. Results showed a strong correlation between alexithymia and experiential avoidance (r = .55, p < .001), with experiential avoidance accounting for 25.4% of the variance in alexithymia. A latent profile analysis identified three distinct subgroups across participants: one with high alexithymia and high experiential avoidance, one with average levels in both, and one with low scores in both. We compared these profiles for their psychopathology levels, showing that the profile highest in both alexithymia and experiential avoidance had the highest symptoms of depression, anxiety, stress, posttraumatic stress disorder, and dissociation. These findings support the attention-appraisal model, suggesting that experiential avoidance may play an important role in alexithymia. When high alexithymia is present, people are generally also engaging in high levels of experiential avoidance. Addressing experiential avoidance may therefore be a useful target in interventions for alexithymia and associated emotional problems.
