    Depressed and swiping my problems for later: The moderation effect between procrastination and depressive symptomatology on internet addiction
    (2019) Hernandez, Cristobal; Rivera Ottenberger, Diana; Moessner, Markus; Crosby, Ross D.; Ditzen, Beate
    Based on insights from the model of compensatory intemet use and emotion regulation theory, this study aimed to explore two possible mechanisms explaining the reliable association between depressive symptomatology and intemet addiction: procrastination on the internet and flow experiences online. Data were collected from 529 high school students, with a mean age of 15.2 years (SD = 1.30), enrolled in six schools in a metropolitan region of Chile. Voluntary participants completed self-reported measures of internet addiction, depressive symptomatology, procrastination on the interne, and flow experiences online. A three-level hierarchical linear model was calculated to evaluate the potential moderator effect of flow and procrastination on the relationship between depressive symptomatology and internet addiction. Results revealed that procrastination moderated this relationship while flow experiences online did not. The findings are discussed in terms of their implications for research and clinical practice, highlighting the importance of considering the intentions behind interne usage.

    Dyadic Coping and Its Underlying Neuroendocrine Mechanisms - Implications for Stress Regulation
    (2019) Zietlow, Anna-Lena; Eckstein, Monika; Hernandez, Cristobal; Nonnenmacher, Nora; Reck, Corinna; Schaer, Marcel; Bodenmann, Guy; Heinrichs, Markus; Ditzen, Beate
    Previous research suggests that neuroendocrine mechanisms underlie inter-individual stress coping in couples. The neuropeptide oxytocin (OT), while regulating stresssensitive HPA-axis activity might be crucial in this process. The purpose of this study was to examine the impact of dyadic coping abilities and OT on HPA-axis outcomes and constructive behavior during couple conflict. We conducted a secondary analysis of our previous database (Ditzen et al., 2009), assessing the modulating role of dyadic coping and intranasal OT on couple conflict behavior. The data revealed a significant interaction effect of the dyadic coping by oneself score and OT on cortisol responses during couple conflict, suggesting that particularly individuals with low a priori dyadic coping benefit from OT in terms of dampened HPA-activity. The results are in line with previous research suggesting OT's central role for stress regulation and prosocial behavior. Furthermore, an interaction with dyadic coping indicates adaptations in the sensitivity of the OT system during the individual attachment and relationship history. These data add to the evidence that the neuroendocrine attachment systems influence couple behavior. Future studies of neurobiological mechanisms underlying dyadic coping will be of high relevance for the development of prevention and intervention programs.

    Objective: Key to reducing COVID‐19 morbidity and mortality and reducing the need for further lockdown measures in Canada and worldwide is widespread acceptance of COVID‐19 vaccines. Vaccine hesitancy has emerged as a key barrier to achieving optimal vaccination rates, for which there is little data among Canadians. This study examined rates of vaccine hesitancy and their correlates among Canadian adults. Methods: This study analyzed data from five age, sex and province‐weighted population‐based samples to describe rates of hesitancy between April 2020 and March 2021 among Canadians who completed online surveys as part of the iCARE Study, and various sociodemographic, clinical and psychological correlates. Vaccine hesitancy was assessed by asking: “If a vaccine for COVID‐19 were available today, what is the likelihood that you would get vaccinated?” Responses were dichotomized into ‘very likely’, ‘unlikely’, ‘somewhat unlikely’ (reflecting some degree of vaccine hesitancy) vs ‘extremely likely’ to get the vaccine, which was the comparator. Results: Overall, 15,019 respondents participated in the study. A total of 42.2% of respondents reported vaccine hesitancy over the course of the study, which was lowest during surveys 1 (April 2020) and 5 (March 2021) and highest during survey 3 (November 2020). Fully adjusted multivariate logistic regression analyses revealed that women, those aged 50 and younger, non‐Whites, those with high school education or less, and those with annual household incomes below the poverty line in Canada (i.e., $60,000) were significantly more likely to report being vaccine hesitant over the study period, as were essential and healthcare workers, parents of children under the age of 18, and those who do not get regular flu vaccines. Believing engaging in infection prevention behaviours (like vaccination) is important for reducing virus transmission and high COVID‐19 health concerns (being infected and infecting others) were associated with 77% and 54% reduction in vaccine hesitancy, respectively, and having high personal financial concerns (worried about job or income loss) was associated with 1.33 times increased odds of vaccine hesitancy. Conclusion: Results point to the importance of targeting vaccine efforts to women, younger people and socioeconomically disadvantaged groups, and that vaccine messaging should emphasize the benefits of getting vaccinated, and how the benefits (particularly to health) far outweigh the risks. Future research is needed to monitor ongoing changes in vaccine intentions and behaviour, as well as to better understand motivators and facilitators of vaccine acceptance, particularly among vulnerable groups.
