چکیده انگلیسی
Suicide, self-injury, and predisposing vulnerabilities aggregate in families. Those at greatest risk often show deficits in two biologically-mediated domains: behavioral control and emotion regulation. This pilot study explored electroencephalographic and cardiovascular indices of self-regulation among typical and suicidal adolescents (nâ¯=â¯30/group) and biological family members (mothers, fathers, and siblings). We measured event-related potentials during a flanker task designed to evoke impulsive responding and respiratory sinus arrhythmia (RSA) at rest and during social rejection. Multilevel models indicate control families' RSA was unaffected by social rejection (slopeâ¯=â¯0.136, pâ¯=â¯.097, dâ¯=â¯0.09), whereas clinical families demonstrated RSA withdrawal (slopeâ¯=â¯â0.191, pâ¯=â¯.036, dâ¯=â¯â0.13). Clinical families displayed weaker positive voltage (Pe) deflections following behavioral errors relative to controls (coefficientâ¯=â¯â2.723, pâ¯=â¯.017, dâ¯=â¯â0.45), indicating risk for compromised cognitive control. Thus, families with suicidal adolescents showed autonomic and central nervous system differences in biological markers associated with suicide risk.
