Although deficiencies in emotional responding have been linked to externalizing behaviors in children, little is known about how discrete response systems (e.g., expressive, physiological) are coordinated during emotional challenge among these youth. We examined time-linked correspondence of sad facial expressions and autonomic reactivity during an empathy-eliciting task among boys with disruptive behavior disorders (n = 31) and controls (n = 23). For controls, sad facial expressions were associated with reduced sympathetic (lower skin conductance level, lengthened cardiac preejection period [PEP]) and increased parasympathetic (higher respiratory sinus arrhythmia [RSA]) activity. In contrast, no correspondence between facial expressions and autonomic reactivity was observed among boys with conduct problems. Furthermore, low correspondence between facial expressions and PEP predicted externalizing symptom severity, whereas low correspondence between facial expressions and RSA predicted internalizing symptom severity.
KeywordsConduct problems; Disruptive behavior; Facial expression; Sadness; Autonomic reactivity Conduct disorder (CD) and oppositional defiant disorder (ODD), jointly labeled as disruptive behavior disorders (DBDs) in the DSM-IV-TR (American Psychiatric Association, 2000), are among the most common mental health problems facing youth (Achenbach & Howell, 1993;Knitzer, Steinberg, & Fleisch, 1991). There is now a growing body of literature suggesting that children and adolescents with DBDs have difficulties with several domains of empathic responding, including emotional processing and self-appraisals of emotional experiences (de Wied, Goudena, & Matthys, 2005;Douglas & Strayer, 1996;Herpertz et al., 2005;Strand & Nowicki, 1999). However, other components of empathic responding such as displays of sad facial expressions and autonomic reactivity have only begun to receive empirical attention (Blair, 1999;de Wied et al., 2005;Douglas & Strayer, 1996;Herpertz et al., 2005).Functionalist theories of emotion suggests that the synchronization of emotional response systems plays a critical role in emotional health and that desynchronization contributes to the emergence and maintenance of psychopathology (see Ekman, 1992;Kring, Kerr, Smith, & Neale, 1993;Levenson, 1994;Mauss, Levenson, McCarter, Wilhelm, & Gross, 2005;Sloan, Strauss, Quirk, & Sajatovic, 1997). According to this perspective, as emotions unfold over time, the coordination of emotional appraisal, expressive behavior, and physiological responses should improve the reliability and precision of emotion cues and promote efficient behavioral and social responses (Levenson, 1994 (Feldman-Barrett, 2006), with some authors finding low to moderate correlations between experiential, behavioral, and physiological response domains (Buck, 1977;Gross & Levenson, 1993,1997Kettunen, Ravaja, Näätänen, Keltikangas-Jarvinen, 2000;Lanzetta, Cartwright-Smith, & Kleck, 1976;Mauss et al., 2005), others reporting discrepancies in the direction of effects (Notar...
