Alterations in the neuroendocrinological stress response to acute psychosocial stress in adolescents engaging in nonsuicidal self-injury.

OBJECTIVE

To investigate the neuroendocrinological stress response to acute psychosocial stress in a clinical sample of female adolescents engaging in nonsuicidal self-injury (NSSI).

METHODS

The Trier Social Stress Test (TSST), a standardized psychosocial stress protocol, was performed in 14 female patients who engaged in NSSI and 14 healthy control subjects. NSSI was assessed by the Functional Assessment of Self-Mutilation (FASM). Salivary cortisol, heart rate, and affective states, assessed by the Positive and Negative Affect Schedule (PANAS), were measured during the TSST.

RESULTS

We found an attenuated cortisol response to acute psychosocial stress in female adolescents with NSSI, whereas no group differences were observed in heart rate and emotional response to the TSST.

CONCLUSIONS

These findings indicate that the HPA axis is hyporesponsive in adolescents with NSSI. Therefore, reduced secretion of cortisol could play a role in promoting vulnerability of these individuals to acute stress and maladaptive stress responses.
