Beneficial effects of human-animal contact on human health have contributed to the wide distribution of animal-assisted interventions (AAIs). While considerable effort has been devoted to the study of human welfare during AAIs, potential effects on therapy animals have been addressed less frequently. The aim of this study was to determine baseline and work-related levels of cortisol, a glucocor-ticoid hormone that mediates physiological responses to arousal, in certified therapy dogs and therapy dogs in training. All dogs (n = 21) participated in weekly group-AAIs in adult mental healthcare. Saliva samples were collected over the course of AAIs and on non-working days and analysed with a cortisol enzyme immunoassay. Analysis of the results revealed that according to their cortisol responses, both therapy dogs and therapy dogs in training were not stressed by AAIs. However, cortisol levels during work in certified therapy dogs performing AAIs on- and off-lead varied significantly, suggesting that further investigation into the use of a lead or other methods of giving therapy dogs opportunities to approach or avoid human contact is needed.

The DSM-5 introduced Internet gaming disorder (IGD) as a condition needing more research. Proposed criteria include tolerance, preoccupation, deceiving, or continued excess despite psychosocial problems. However, studies suggest differences between addicted and engaged players. Therefore, this study investigated differences between engagement and addiction in a German-speaking sample of expert World of Warcraft players. Using an online-based questionnaire, 682 participants were surveyed (Mage=23.26 years; 84.9% male) from German-speaking areas. An adapted version of the "Asheron's call" questionnaire (which covers six addiction criteria, including salience, euphoria, and tolerance), the WHOQOL-BREF, the Gaming Motivation Scale, the BDI, the SPIN, and a brief version of the personality questionnaire BFI-10 were used. The average gamer in the sample played on level 87.93 and had been playing for 5.42 years. Addicted players had higher scores on the BDI and SPIN and significantly lower scores in all dimensions of quality of life. Addicted gamers played for 39.25 hours per week (engaged players: 11.93 hours per week) with significantly higher scores in items tapping achievement and immersion. There were differences regarding the BFI-10 in terms of "agreeableness," "conscientiousness," and "neuroticism." The results suggest that factors such as achievement and immersion set engaged and addicted users apart. Addiction seems to be significantly more connected to other psychopathologies such as depression and social anxiety. The results suggest that euphoria, tolerance, and cognitive salience should be handled with caution when it comes to a classification of IGD similar to (behavioral) addiction.

Veterinary medicine is a highly complex profession that includes a very specific set of stressors that range from individual to social aspects, with several of them being relevant risk factors for a variety of conditions. The aim of this systematic review was to identify and cluster the material on stressors and suicidality in the veterinarian practice published during the last 10 years. The systematic review was conducted employing the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using PubMed, PsycNet, Google Scholar, Medline, PsycINFO, PSYNDEX and Web of Science (2012–present) by two independent researchers resulting in the inclusion of 30 quantitative and mixed methods studies. Results of these studies on stressors were categorized using the bio-psycho-social model showing that social stressors play a prominent role. This category includes the largest number of stressors indicating that the human–human interactions in the veterinarian practice are the main stressor, underlining that training in communication techniques is a potential starting point for interventions. In addition to stressors, the results showed an additional category “psychological consequences” describing mental health disorders and suicide. Although there are still gaps in research there is enough evidence to establish more tailored health promotion measures for veterinarians.

Within the field of veterinary medicine the gender distribution has changed, since most graduates are now females. Studies show that female veterinarians represent a vulnerable group for stress and stress-related illnesses. The goal of the study was to identify typical profiles of stress management strategies and to clarify if vets are well-equipped to cope with occupational stressors. Within a cross-sectional design 78 female veterinarians from Austria and Germany were surveyed using a self-report test-battery assessing twenty different coping styles. Statistical analysis included one sample t-tests and Cohen’s d as a concurrent effect size measure. The results showed that female veterinarians are significantly more likely to use negative coping styles for their stress e.g., rumination (t(74) = 6.733, p = < 0.001, d = 0.726) or escapism (t(72) = 2.173, p = 0.033, d = 0.281) when compared to the norm population. Amongst other studies these findings contribute to a systematic diagnosis which is necessary for the development and implementation of standardized stress management interventions for the veterinary education and training e.g., courses for improving communication and stress management skills and regular supervision or intervision (exchange with professional peers). Due to existing stigmatization concerning mental health, low-barrier counseling services should be provided for veterinarians who already feel stressed.
