Self-Esteem, Social Anxiety, and Affective Lability as Predictors of Academic Achievement in Pediatric Nursing Students: A Mediation Analysis
,
Abstract
Objective: To assess levels of self-esteem, social anxiety, and affective lability among pediatric nursing students; to examine their associations with academic achievement; and to test whether social anxiety and affective lability mediate the self-esteem–achievement relationship.
Method: A descriptive cross-sectional study was conducted among 370 nursing students aged 17-24 years using purposive sampling. Instruments included the Coopersmith Self-Esteem Scale (self-esteem), the Liebowitz Social Anxiety Scale-Self-Report (LSAS-SR), the Affective Lability Scale (ALS-18), and academic achievement records from the pediatric nursing course. Sociodemographic variables were also collected. Data were analyzed using Pearson correlations and mediation analysis with Hayes PROCESS Model 4.
Results: Students demonstrated moderate self-esteem, mild-to-moderate social anxiety, and clinically notable affective lability (mean ALS-18 = 42.3 ± 11.7; scores > 40 indicate clinically notable emotional dysregulation). Self-esteem showed a significant positive correlation with academic achievement (r = 0.42, P < 0.01). Social anxiety (r = -0.38, P < 0.01) and affective lability (r = -0.36, P < 0.01) were each negatively correlated with both self-esteem and academic achievement. Mediation analysis revealed that social anxiety and affective lability partially mediated the relationship between self-esteem and academic achievement (indirect effect = 0.19, 95% CI: 0.08 to 0.33), accounting for 41% of the total association between self-esteem and academic achievement (proportion mediated = 0.41). No significant associations were found between sociodemographic variables and self-esteem.
Conclusion: Self-esteem is positively associated with academic achievement among pediatric nursing students. Cross-sectional mediation analysis indicates that this association is statistically consistent with a model in which social anxiety and affective lability together account for 41% of the total association. However, causal interpretation requires longitudinal replication. Psychiatric screening for emotional dysregulation and social anxiety using validated tools such as the ALS-18 and LSAS may help identify at-risk students, but experimental studies are needed to test whether interventions targeting these constructs improve academic outcomes.
