This study examined the association between positivity (POS) and salivary cortisol and alpha-amylase (alpha-Amy) production in healthy male volunteers. The findings showed distinct patterns of salivary cortisol and alpha-Amy production between individuals with high POS and low POS. Further research is needed to confirm whether these differences are linked to a better quality of life in individuals with higher levels of positivity.
A large variety of positive outcomes including social adjustment, psychological well-being and health, have been recently closely associated with positivity (POS). On the assumption that differences in the POS degree might be associated with different individual neuroendocrine assets that enables people to cope effectively with stress, the present study examined the association between POS, salivary cortisol and alpha-Amylase (alpha-Amy) production in a group of healthy male volunteers university students, respectively scoring high (POS-H,N = 10) and low (POS-L,N = 10) in POS. Participants were selected from a larger sample of 300 students of the Medical School at Sapienza University of Rome on the basis of their positivity level: POS was analysed and the upper and lower 25% were invited to participate in this new study. The findings report a distinct salivary cortisol and alpha-Amy production in the study population: in comparison to the POS-H group, the POS-L subjects presented a lower salivary cortisol awake response (CAR) and a flattened alpha-Amy production at 30 and 60 min after awakening. In addition, salivary cortisol and alpha-Amy areas under the curve (AUCs), which were calculated as indicators of the two subclinical biomarkers production during the first hour after awakening, resulted significantly lower in the POS-L group in comparison to the POS-H group. Further studies on larger and different populations are needed to definitively confirm that the different cortisol and alpha-Amy secretion patterns between POS-H and POS-L individuals is associated with a potentially better capacity to preserving an adequate quality of life in individuals being equipped with a system apparently able to better respond to external and/or internal stimuli. Lastly, a better understanding of the biological correlates of POS is crucial to design psychological interventions able to take advantage of individuals' assets and thus to integrate and strengthen the efficacy of traditional medications.
