ABSTRACT
This study examined the determinants of sustained physical activity. Eighty-four participants undertook a 7-weeks walking regime (i.e., a 1-h biometrically-monitored walk, at least 5 days/week), with bioelectrical impedance (BIA) and total cholesterol capillary blood measurements performed before and after programme. To investigate behavioural habit formation, 7 weeks after walking termination, all participants were interviewed and (health) re-tested. Data were modelled with an artificial neural network (ANN) cascading algorithm. Our results highlight the successful prediction of continued physical activity by considering one's physical fitness state, the environmental living context, and risk for cardiovascular disease. Importantly, those artificial neural network models also taking body mass index (BMI) and blood cholesterol as predictors excel at predicting walking continuation (i.e., predictions with 93% predictability). These results are first to highlight the type and importance of available physiological drivers in maintaining a sustained physical activity regime such as walking. They are discussed within the framework of habit formation and the nowadays health and/or wellbeing focus.
ABSTRACT
People's perceptions of climate change represent a growing concern, especially when these perceptions entail the denial of climate change. Past studies have highlighted the detrimental role of conspiracist beliefs concerning climate change regarding people's perceptions on this matter. However, the effects of generic conspiracy beliefs and the different types of beliefs determining skepticism about climate change, as well as that of an individual's personality, are still an open area of inquiry. Our cross-sectional study (N = 842) explored the relationships between the degree to which people hold different generic conspiracy beliefs, their personality characteristics (as defined within the Big Five taxonomy), and climate change beliefs (i.e., in its occurrence and anthropogenic causation). Results indicated common predictors of these dimensions of climate change beliefs, specifically three of the five types of generic conspiracy beliefs, extraversion, agreeability, and intellect/imagination as personality factors. While conspiracy beliefs related to personal well-being emerged as related to climate change skepticism, those in government malfeasance and information control were found to be associated with more acceptance of climate change and its anthropogenic causation. These findings reveal a mixed pattern of relationships between different conspiracist beliefs and climate change perceptions and suggest the complex psychological and ideological underpinnings of the attitudes towards climate change.
