A latent profile analysis of trait emotional intelligence to identify beneficial and risk profiles in well-being and job performance: a study among Japanese eldercare nurses

Trait emotional intelligence (EI) is a noteworthy psychological resource in nursing. However, its effects on well-being and job performance are inconsistent. Thus, we explored the latent beneficial and risk profiles of trait EI among 461 Japanese eldercare nurses. Latent profile analysis revealed six latent profiles. In addition, multivariate analysis of covariance (MANCOVA) showed that the profile with the highest overall scores on the trait EI dimensions was associated with the most beneficial outcomes (better well-being, higher job performance). In contrast, the profiles with lower overall scores on the trait EI dimensions showed negative outcomes. Moreover, a disproportional profile, ch…

Trait Emotional Intelligence, Self-Reported Affect, and Salivary Alpha-Amylase on Working Days and a Non-Working Day

This study examined the relationship between trait emotional intelligence (EI) and variation in psychological (positive affect: PA, negative affect: NA) and psychophysiological (salivary alpha-amylase: sAA) indicators among Japanese employees over 3 consecutive days (working day 1, non-working day, working day 2). The analyses revealed that higher trait EI was associated across the days with higher PA, but not with NA. Moreover, diurnal sAA levels were lower in the high trait EI group than in the low trait EI group on the intervening non-working day, and this difference between the EI groups continued to show a tendency to significance on working day 2. The results indicate that higher EI m…

Associations of Trait Emotional Intelligence with Social Support, Work Engagement, and Creativity in Japanese Eldercare Nurses

Associations of Trait Emotional Intelligence with Social Support, Work Engagement, and Creativity in Japanese Eldercare Nurses

Work-related resources can be positive antecedents of employee work engagement (WE) and creativity. Although trait emotional intelligence (EI) and social support may be crucial resources in nursing, their relationships with WE and creativity remain unclear. Hence, with special focus on the role of trait EI, we examined this relationship by applying the job demands-resources (JD-R) model. The participants were 489 eldercare nurses in Japan (female: n = 401; male: n = 88; age = 39.5 ± 11.0 years). The results showed positive associations between EI and the other studied variables. Furthermore, moderated mediation analyses revealed that higher trait EI enhanced the positive association among t…

Trait emotional intelligence and its associations with subjective and physiological well-being

The present thesis examined the association between trait emotional intelligence (EI) and well-being (subjective well-being [SWB] and physiological well-being) among Japanese participants (eldercare nurses and undergraduate university students). This research had four primary goals: First, to identify profiles of trait EI and to investigate their association with SWB (Study I); second, to examine the role of trait EI in the process of SWB (Study II); third, to investigate the association of trait EI with psychological state and physiological well-being in a laboratory-based stress induction condition (Study III); and fourth, to investigate the association of trait EI with affect and physiol…
