Abstract
OBJECTIVE: The present study aims to explore whether hair cortisol concentration is associated with explicit stress or implicit stress in female methamphetamine addicts. METHODS: Hair samples were collected from 51 female methamphetamine addicts from inpatient addiction treatment programs. Perceived stress was assessed by both explicit and implicit measures through the Perceived Stress Scale (PSS) and the Implicit Association Test (IAT), respectively. RESULTS: The positive relationship between hair cortisol concentration with D-scores of the IAT reached statistically significant difference. A marginal correlation between hair cortisol concentration and scores of the PSS was observed. Additionally, linear regression analysis indicated that D-scores of the IAT are strongly predictive of hair cortisol concentration. CONCLUSION: Hair cortisol concentration is strongly related to implicit stress but only weakly related with explicit stress. Copyright Â
