2.2.2. Anxiety (Outcome)

Anxiety symptoms were assessed using the Spanish version of the Beck Anxiety Inventory (BAI) [14], which has shown high consistency (Cronbach alpha coefficient = 0.93) and moderate correlation (r = 0.32) with the Trait-Anger scale of the STAXI 2 [15] The BAI is composed of 21 items. Each item consists of a different anxiety symptom in which the participant scores how he/she felt in relation to that symptom during the last month, on a scale that varies from 0 (Not at all) to 3 (Severely, it bothered me a lot). The overall scores range from 0 to 63. Scores ranging from 0–7 indicate minimal/no anxiety symptoms; 8–15 indicate mild anxiety symptoms; 16–25 indicate moderate anxiety symptoms, and 26–63 indicate severe anxiety symptoms [14]. For this study, the group of severe anxiety was underrepresented with 4 participants, so they were excluded from the analysis.
