Direct and indirect effects of the temperament and character on alexithymia: a pathway analysis with mood and anxiety.
OBJECTIVE
We aimed to assess the pathway from personality to alexithymia through mood and anxiety as mediators.


METHODS
Three hundred thirty-four subjects (130 male), whose psychiatric health was verified by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I disorders, completed the Toronto Alexithymia Scale-20 (TAS-20), the Temperament and Character Inventory, the State-Trait Anxiety Inventory (STAI), and the Center for Epidemiological Studies-Depression scale (CES-D). The schematic models for the pathway analysis from Temperament and Character Inventory (TCI) to TAS-20 scores were made.


RESULTS
Low reward dependence (RD), low self-directedness (S-D), and high cooperativeness (CO) had paths to TAS-20 total (P = .000, P = .000, and P = .042, respectively). S-D had also an indirect path via STAI-state to TAS total. On TAS-20 factor 1, low RD, low S-D, and high self-transcendence (ST) had direct effects (P = .004, P = .000, and P = .000, respectively). S-D had also an indirect path via STAI-state and (CES-D) on TAS-20 factor 1. On TAS factor 2, low novelty seeking (NS), high harm avoidance (HA), low RD, low S-D, and high cooperativeness (CO) had direct effects (P = .005, P = .011, P = .000, P = .000, and P = .004, respectively). On TAS-20 factor 3, low RD and S-D had direct effects (P = .002 and P = .000, respectively).


CONCLUSIONS
Current results suggest that although alexithymia is affected by the personality, state-dependent mood and anxiety may mediate the relationship between alexithymia and personality.
