Self-Esteem Assessment Based on Self-Introduction: A Multimodal Approach to Personality Computing

= 63) and collected 40-second self-introduction videos along with Rosenberg Self-Esteem Scale (RSES) scores. Features were extracted from three modalities-visual, audio, and text-and three-class models were trained using the dataset of 211 participants. Results indicated that the late-fusion multimodal model achieved the highest performance (Accuracy, ACC = 0.447 ± 0.019; Macro-averaged F1, Macro-F1 = 0.438 ± 0.020) and further demonstrated cross-sample generalizability when validated on the independent sample of 63 participants (ACC = 0.381, Macro-F1 = 0.379). Reliability testing showed good interrater consistency (Fleiss' κ = 0.723, Intraclass Correlation Coefficient, ICC = 0.745). Criterion-related validity analyses indicated that the proposed method was significantly correlated with life satisfaction, subjective happiness, positive and negative affect, depression, anxiety, stress, relational self-esteem, and collective self-esteem. Moreover, incremental validity analyses indicated that the multimodal model provided additional predictive value for positive affect beyond the RSES. Taken together, these findings provide preliminary evidence that multimodal behavioral features can assist in achieving automated self-esteem evaluation, offering a feasible, low-burden complement to traditional self-report.
