“…inconsistencies. Because the field of psychoneuroendocrinology relies heavily on IAs for the measurement of hormone concentrations, this potential instability in IA validity across studies poses a direct and serious challenge to the reproducibility of research in the field (see Baker, 2015;Roy et al, 2019). Follow-up research will be needed to identify the exact causes for instability in EIA-MS correspondence, such as variance in antibody performance or matrix interference, to improve measurement validity and in turn enhance reproducibility.…”

“…Two recent studies that adopted mass-spectrometry based testosterone measurement and used the same outcome measure as previous studies found some evidence for reproducible dual-hormone interactions (e.g. Ronay et al, 2018;Roy et al, 2019).…”

The challenge hypothesis makes specific predictions about the association between testosterone and status-seeking behaviors, but the findings linking testosterone to these behaviors are inconsistent. The dual-hormone hypothesis was developed to help explain these inconsistencies. Specifically, according to this hypothesis, testosterone's association with status-seeking behavior depends on levels of cortisol. Here, we (1) describe the dual-hormone hypothesis in relation to the challenge hypothesis; (2) review recent studies that tested the dual-hormone hypothesis as well as meta-scientific evidence of heterogeneous dual-hormone findings across studies; (3) discuss potential explanations for this heterogeneity, including methodological considerations, contextual factors, and individual differences; and (4) provide recommendations for new work aimed at testing and extending the dualhormone hypothesis.

“…Indeed, it is acknowledged that there is both a smaller prevalence of psychopathic traits in females compared to males (Verona & Vitale, 2006) and the manner by which said psychopathic traits and behaviours manifest might differ as a function of sex (Cale & Lillienfeld, 2002). However, not only have associations between testosterone and psychopathy been documented in women (Glenn et al, 2011, Roy et al, 2019, but there was no variation between PCOS+ or PCOS-groups across any of the facets of psychopathy, either affective (i.e., interpersonal manipulation, callous affect) or behavioural (i.e., erratic lifestyle, anti-social behaviour) in nature.…”

“…Interestingly however, when measuring psychopathic traits explicitly, the positive relationships between testosterone and psychopathy documented in Welker et al (2014) and Roy et al (2019) were only present in the context of high, not low, cortisol. Specifically, the associations reported in Roy et al held for the interpersonal manipulation, erratic lifestyle, and antisocial, but not affective facets of psychopathy explored in the current research.…”

A comparison of the manifestation of psychopathic traits between women with and without Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome (PCOS) impacts 5-10% of women of reproductive age and is characterized by increased testosterone, psychological distress, and dampened affect. However, little research exists into wider personality traits associated with increased testosterone, such as psychopathy. As such, psychopathic traits in a community sample of women with (n=82) and without (n=85) PCOS were compared using MANOVA. No group differences were found in any facet of psychopathy (interpersonal manipulation, callous affect, erratic lifestyle, anti-social behavior). The null results reported here increase our knowledge pertaining to personality in women with PCOS, particularly with relation to historically-deviant personalities, such as psychopathy.
