Link Between Irrational Beliefs and Important Markers of Mental Health in a German Sample of Athletes: Differences Between Gender, Sport-Type, and Performance Level

Adverse competition-related cognitions questionnaire (ACCQ): Development and preliminary validation of a measure identifying different factors of athletes' cognitions related to competitions

This research project presents the development and preliminary validation of a German version of the Adverse Competition-related Cognitions Questionnaire (ACCQ) and comprises four studies. In Study 1, 101 athletes and 124 coaches from different team and individual sports generated a large pool of cognitions, which was reduced to an initial item pool of 54 cognitions through a multi-step procedure with different experts. In Study 2, the underlying factor structure of the questionnaire was examined by an exploratory factor analysis (N2 = 348), which revealed six factors (athletic comparison, coach devaluation, devaluation of one's own performance, appreciation by coach and family, inner resistance against competitions, and general exhaustion) with 26 items retained. Subsequently, in Study 3, the results were re-examined with a confirmatory factor analysis (CFA, N3 = 419; CFI = 0.91, RMSEA = 0.06, SRMR = 0.06). In addition, preliminary support for the construct validity (i.e., convergent, divergent, and concurrent validity) of the ACCQ was obtained by examining associations among the ACCQ subscales and theoretical correlates such as social comparison, cognitive interference, irrational performance beliefs, and fear of negative evaluation. In Study 4, a second CFA (N4 = 153; CFI = 0.89, RMSEA = 0.06, SRMR = 0.07) was conducted to test the identified 6-factor solution in a sample of high-performance competitive athletes. With its broad range of factors, the ACCQ provides a useful and valid measure for assessing different adverse competition-related cognitions, offering a wide range of potential applications in research and sport psychology practice.

The Mind-Body Problem in the Context of Neuropsychiatric Symptoms in Patients with Coronavirus Disease 2019

Objective

This study is to determine the possible pathophysiological parameters associated with the development of anxiety and impaired consciousness in patients with acute coronavirus disease (COVID-19).

Methods

Descriptive pathophysiological and pathopsychological data was collected from 89 patients hospitalized due to COVID-19 across 7 infectious hospitals, where 14 trainees in psychiatry and neurology collected data from December 2020 to June 2021. Contingency tables and logistic regression analyses were made to reveal associations and to detect predictors of patients' states of anxiety or impaired consciousness.

Results

Anxiety and impaired consciousness were observed in 28 patients (31.50%); 22 (25.00%) presented with anxiety symptoms, and 7 (7.90%) had impaired consciousness. The degree of their association was low (Fisher's exact = 0.675 (df = 1), P = .495). Different pathophysiological mechanisms were shown to determine the development of anxiety or impaired consciousness within COVID-19. Predictors of anxiety were oxygen saturation (OR = 1.26; 95% CI, 1.04-1.54; P = .021), cardiovascular disorders (OR = 0.14; 95% CI, 0.04-0.52; P = .003), disorders of the nervous system (OR = 0.05; 95% CI, 0.01-0.84; P = .038), and urogenital system (OR = 0.13; 95% CI, 0.02-0.87; P = .035). The predictive power of the model was 80.23% (P ≤ .001). The development of impaired consciousness was associated with age (OR = 1.11; 95% CI, 1.01-1.21; P = .025) and C-reactive protein level (OR = 1.02; 95% CI, 0.99-1.04; P = .060), and the predictive power of the model was 94.52% (P ≤ .001).

Conclusion

The prevalence of psychopathological disorders associated with acute COVID-19 was high: n = 28 (31.50%) for anxiety and impaired consciousness. Moreover, a 1.00% increase in the saturation index was associated with a 1.3-fold increase in the patient's risk of developing anxiety. Thus, anxiety symptoms may be considered within a personality rather than an infectious-inflammatory response to COVID-19.

The Influence of Physical Exercise Frequency and Intensity on Individual Entrepreneurial Behavior: Evidence from China

Physical exercise can benefit individuals' physical and mental health and also influence individuals' long-term behavioral choices. Doing exercise is particularly important given that physical exercise can impact individuals' cognitive abilities and positive emotional states, which may further impact entrepreneurial behavior. Therefore, understanding the relationship between exercise and entrepreneurial behavior is essential, because it can provide policy suggestions for popularizing athletic activities and boosting entrepreneurship. Consequently, the present study examined whether physical exercise could predict entrepreneurial behavior and the possible psychological mechanisms within this relationship. Based on the 2017 Chinese General Social Survey (CGSS2017), this study tested the hypotheses using the Probit and Tobit models. The results showed that individuals' physical exercise intensity and frequency positively affected their entrepreneurial behavior. In addition, five variables moderated the relationships between physical exercise and individual entrepreneurial behavior: urban-rural differences, education level, marital status, the existence of minor children, and age. Moreover, positive emotions and physical/mental health mediated the influence of physical exercise (exercise frequency and exercise intensity) on individual entrepreneurial behavior. Endogeneity explanations were ruled out by including instrumental variable, copula terms and adopting coarsened exact matching.
