The 20-item Toronto Alexithymia Scale (TAS-20; Bagby, Parker, & Taylor, 1994; Bagby, Taylor, & Parker, 1994) is the most widely used self-report measure of the alexithymia construct. The TAS-20 comprises 3 factors that assess difficulty identifying feelings, difficulty describing feelings, and externally oriented thinking. Although the instrument is being increasingly used with adolescent respondents, the psychometric properties of the TAS-20 have not been systematically evaluated in preadult populations. In the present study, we examined measurement invariance of the factor structure, internal reliability, and mean levels of responses on the TAS-20 in groups of younger adolescents (aged 13-14 years), middle adolescents (aged 15-16 years), and older adolescents (aged 17-18 years), as well as in a comparison group of young adults (aged 19-21 years). Formal readability analysis of the TAS-20 assessment was also conducted. Results revealed systematic age differences in the factor structure and psychometric properties of the TAS-20, with the quality of measurement progressively deteriorating with younger age. Much of this effect could be attributed to the reading difficulty of the scale. The use of the TAS-20 with teenage respondents is not recommended without appropriate adaptation and further psychometric validation. Several adaptation strategies are discussed.

Despite a wealth of research on the validity of alexithymia and its association with a number of common medical and psychiatric disorders, the fundamental question of whether alexithymia is best conceptualized as a dimensional or categorical construct remains unresolved. In the current investigation, taxometric analysis is used to examine the nature of the latent structure of alexithymia. Several nonredundant taxometric procedures were performed with item sets from the 20-item Toronto Alexithymia Scale (R. M. Bagby, J. D. A. Parker, & G. J. Taylor, 1994) as indicators. These procedures were applied separately in large community (n = 1,933) and undergraduate (n = 1,948) samples and in a smaller sample of psychiatric outpatients (n = 302). The results across various taxometric procedures and the different samples provide strong support that alexithymia is a dimensional construct. Some theoretical implications of these findings for research on the alexithymia construct are discussed.

Certain coping strategies alleviate stress and promote positive psychological outcomes, whereas others exacerbate stress and promote negative psychological outcomes. However, the efficacy of any given coping strategy may also depend on personal resiliency. This study examined whether personal resiliency moderated the effects of task-oriented, avoidance-oriented, and emotion-oriented coping strategies on measures of depression, anxiety, stress, positive affect, negative affect, and satisfaction with life. Results (N = 424 undergraduates) showed higher personal resiliency was associated with greater use of task-oriented coping strategies, which were in turn associated with more adaptive outcomes, and less reliance on nonconstructive emotion-oriented strategies, which in turn were associated with poorer psychological outcomes. In addition, individual differences in personal resiliency moderated the effects of task-oriented coping on negative affect and of emotion-oriented coping on negative affect and depression. Specifically, proactive task-oriented coping was associated with greater negative affect for people lower in personal resiliency. Moreover, high personal resiliency attenuated the negative effects of emotion-oriented coping on depression and negative affect. The effects of avoidance-oriented coping were mixed and were not associated with or dependent on levels of personal resiliency.

Although several brief instruments are available for the emotional intelligence (EI) construct, their conceptual coverage tends to be quite limited. One notable exception is the short form of the Emotional Quotient Inventory (EQ-i:S), which measures multiple EI dimensions in addition to a global EI index. Despite the unique advantage offered by the inventory, psychometric properties of the EQ-i:S scores have not yet been systematically evaluated. Such an evaluation was the main goal of the present investigation. Using data from 2,508 undergraduates, the authors conducted 2 studies involving factor structure, internal reliability, 6-month temporal stability, and construct validity of the EQ-i:S responses, both for the total EQ scale and for each constituent dimension. The results supported the multidimensional measurement structure of the EQ-i:S, with each dimension producing internally consistent, temporally stable, and theoretically meaningful responses. Scores on the EQ-i:S were associated more strongly with performance on an ability test of EI and with a conceptually similar construct of alexithymia than with the broader dimensions of basic personality and explained nontrivial amounts of incremental variance in the criterion symptoms of attention deficit/hyperactivity disorder. Moreover, scores on each EQ-i:S dimension exhibited unique patterns of associations with the validation variables. The discussion highlights the advantages of the multidimensional approach in the assessment and study of EI.

Amid the growing efforts to promote positive youth development, trait emotional intelligence (TEI) has emerged as an important protective factor in the processes of resilience and adaptation. The inclusion of a brief form of the Emotional Quotient Inventory-Youth Version (EQi:YV-Brief) in the Canadian National Longitudinal Survey of Children and Youth (NLSCY) presents a unique opportunity to study the developmental dynamics of TEI during the transition from childhood to adolescence. However, before drawing any inferences about construct continuity and change, researchers must establish that the EQi:YV-Brief functions equivalently over time. This study tested configural, metric, scalar, and residual measurement invariance of the EQi:YV-Brief over a 6-year period from late childhood (age 10-11) to adolescence (age 16-17). Longitudinal mean and covariance structures models were fitted to the data from 773 NLSCY participants (51% girls) who completed the EQi:YV-Brief at 4 biennial cycles. Three of the 4 EQi:YV-Brief subscales were found to be fully invariant at ages 12-13 through 17-18 and partially invariant at age 10-11. Controlling for partial noninvariance, we also investigated patterns of rank-order stability and mean-level change in TEI. These exploratory analyses showed that individual differences in TEI became increasingly more stable with age and that changes in mean TEI levels followed a complex nonlinear pattern over time. The results supported the longitudinal utility of 3 of the 4 EQi:YV-Brief subscales used in the NLSCY, supporting their further use in research on the developmental dynamics of TEI.
