BACKGROUND: Texting has become central to social life, with adverse effects on physiological functioning. Research into the impact of texting on cortisol secretion is limited. AIM: Thus study aimed to determine how receiving mobile text messages affected salivary cortisol concentrations and investigate the moderating effects of stress, anxiety and depression on cortisol secretion. SETTING: Undergraduate physiology students attending physiology lectures at the Faculty of Health Sciences, University of the Free State, 2016. METHODS: An experimental, crossover, quantitative design was used. Participants were involved over two consecutive days, receiving mobile text messages (intervention) on one day and acting as their own control on the other. Self-reported data on stress, anxiety, depression and subjective experience of the study, and saliva samples were collected. Text frequency and wording (neutral, positive, negative) were varied among participants. RESULTS: Forty-eight students participated in the study. Salivary cortisol concentrations did not differ significantly between the intervention and control days. High anxiety levels were associated with increased cortisol concentrations. No associations with cortisol concentrations were documented in low to moderate anxiety, stress, depression or how participants experienced the intervention. There were no significant differences between text frequency, text emotion and change in cortisol concentrations on the intervention day CONCLUSION: Receiving mobile text messages did not elicit a significant cortisol response in participants. CONTRIBUTION: Findings added to the body of knowledge about the effect of texting on student learning by measuring salivary cortisol concentrations in a lecture setting, with investigation into the moderating effects of stress, anxiety, depression and participants' subjective experience.
