Latent Profile Analyses of Generalized Anxiety and Depressive Symptoms in Primary Care Patients

Le résumé fourni par la source

Background: Despite their frequent comorbidity of depression and anxiety, previous studies have focused on their co-occurrence without considering symptomatic heterogeneity across patients. We aimed to identify distinct profiles of anxious-depressive symptoms and associated characteristics. Method: Participants were 1,061 patients from the PsicAP clinical trial. Latent Profile Analysis was used to identify distinct subgroups of patients, and multinomial logistic regression models examined associations person-related characteristics. Results: Five distinct symptomatic profiles were identified: 1) mild symptoms (23.66%); 2) moderate depression and mild anxiety symptoms (16.78%); 3) moderate depression and anxiety symptoms (25.64%); 4) moderate-severe symptoms without suicidal thoughts (24.59%); and 5) moderate-severe symptoms with suicidal thoughts (9.33%). Regression analyses showed that higher scores in somatization, disability, emotional suppression, rumination, and metacognitive beliefs, as well as lower quality of life and social support, were significantly associated with more severe profiles. Conclusions: Considering symptomatic heterogeneity in primary care is important for personalizing treatments based on individual profiles. This approach may optimize healthcare resources by offering tailored care.
