Original article: Grotzinger, A. D., Mann, F. D., Patterson, M. W., Tackett, J. L., Tucker-Drob, E. M., & Harden, K. P. (2018). Hair and salivary testosterone, hair cortisol, and externalizing behaviors in adolescents. Psychological Science, 29, 688–699. doi:10.1177/0956797617742981
In the original article, there were five instances in which the unit of measure for hair cortisol and testosterone was given as pg/ml instead of pg/mg. The following are corrected versions of these passages:
“The lower limit of sensitivity for both hair testosterone and cortisol was 0.1 pg/mg (Gao et al., 2013).” (p. 691)
“Participants with below-threshold values were, therefore, given a value of 0.1 pg/mg, because excluding these participants altogether would have omitted informative data and potentially biased results.” (p. 691)
“Sensitivity analyses excluding participants below the 0.1 pg/mg threshold for hair testosterone also indicated the same general pattern of findings, with two notable exceptions (see Table S5 in the Supplemental Material).” (p. 693)
Table 2, Column 1, Row 3: “Hair testosterone (pg/mg)” (p. 694)
Table 2, Column 1, Row 4: “Cortisol (pg/mg)” (p. 694)
The article will be updated to reflect these changes.
