The Development of Three Questionnaires to Assess Beliefs about Green Exercise

[DNVF Memorandum: Objectives and Methods of Physical Activity-Related Health Services Research]

The DNVF Memorandum: Objectives and Methods of Physical Activity-Related Health Services Research summarizes, for the first time, the highly interdisciplinary and interprofessional field of physical activity-based health care in the German healthcare system. In addition to providing a conceptual framework and definition of key measures and concepts in physical activity-related health care research, existing research gaps and needs are identified, and methods for advancing this relatively young field of research are described. A particular focus of this study is the relevant outcome parameters and their standardized assessment using established and valid measurement tools. The memorandum aims to establish a general understanding of the complex subject of promoting physical activity and sports therapy in the context of healthcare, to give an impulse to new research initiatives, and to integrate the currently available strong evidence on the effectiveness of physical activity and exercise into healthcare.

Psychophysiological mechanisms underlying the effects of outdoor green and virtual green exercise during self-paced walking

Physical activity in the presence of nature can lead to additional, more distinct mental health benefits such as lower stress and anxiety levels and an overall better psychological state when compared to indoor physical activity. Interestingly, the brain mechanisms underlying the effects of green exercise (GE) and virtual green exercise (VGE) on psychological responses are hitherto under-researched. The present study sought to deepen our understanding of the brain mechanisms underlying the effects of GE and VGE during self-paced walking. Thirty individuals took part in the present study. Two experimental (i.e., GE and VGE) and a control condition (CO) were administered in a randomized and counterbalanced order. Participants were asked to walk for ¼ mile at a pace of their choosing and self-report their psychological states at various timepoints during the exercise trials. Heart rate variability and the brain's electrical activity were monitored continuously throughout the experimental protocol. An accelerometer was used to identify the beginning and end of each step. The results indicate that both experimental manipulations were sufficient to influence the majority of psychological and psychophysiological parameters. The most pronounced effects were identified for GE when compared to CO and VGE. VGE was also sufficient to evoke positive emotions and partially reallocate attention externally, although such effects were less pronounced than those observed for GE. The brain mechanisms underlying the abovementioned psychophysiological responses may be associated with significant changes in theta activity throughout the cerebral cortex as well as increased connectivity in the frontal and parietal areas.

Applying behaviour change models to policy-making: development and validation of the Policymakers' Information Use Questionnaire (POLIQ)

BACKGROUND

The purpose of this study was to develop and validate the Policymakers' Information Use Questionnaire (POLIQ) to capture the intention of individuals in decision-making positions, such as health policy-makers, to act on research-based evidence in order to inform theory and the application of behaviour change models to decision-making spheres.

METHODS

The development and validation comprised three steps: item generation, qualitative face validation with cognitive debriefing and factorial construct validation. Confirmatory factor analysis was applied to estimate item-domain correlations for five predefined constructs relating to content, beliefs, behaviour, control and intent. Cronbach's alpha coefficient was calculated to assess the overall consistency of questionnaire items with the predefined constructs. Participants in the item generation and face validation were health and policy researchers and two former decision-makers (former assistant deputy ministers) from the Canadian provincial level. Participants in the construct validation were 39 Canadian decision-makers at various positions of municipal, provincial and federal jurisdiction who participated in a series of policy dialogues focused on childhood disability.

RESULTS

Cognitive debriefing allowed for small adjustments in language for clarity, including simultaneous validation of the English and French questionnaires. Participants found that the questions were clear and addressed the domains being targeted. Internal consistency of items belonging to the respective questionnaire domains was moderate to high, with estimated Cronbach's alpha values ranging from 0.67 to 0.84. Estimated item-domain correlations indicated moderate to high measurement performance for the domains norm, control and beliefs, whereas weak to moderate correlations resulted for the constructs content and intent. Estimated imprecision of factor loadings (95% confidence interval widths) was considerable for the questionnaire domains content and intent.

CONCLUSION

Measuring decision-makers' behaviour in relation to research evidence use is challenging. We provide initial evidence on face validity and appropriate measurement properties of the POLIQ based on a convenience sample of decision-makers in social and health policy. Larger validation studies and further psychometric property testing will support further utility of the POLIQ.

Intention to comply with solid waste management practices among households in Butajira town, Southern Ethiopia using the theory of planned behavior

Background

One of the world’s most serious environmental issues is solid waste management. It is critical for researchers to understand the intention to comply with solid waste management. Thus, we aim to determine the intention to comply with solid waste management practice among households in Butajira Town using the Theory of Planned Behavior.

Method

A community-based cross-sectional study was conducted on a sample of 422 households in Butajira from June 1 to June 30, 2020. The constructs and principles of the theory of planned behavior (TPB) were measured. We selected using a systematic sampling method and collected data by using a structured interviewer-administered questionnaire. Data was analyzed using SPSS version 25.0. The predictors of intention to practice solid waste management were identified using a multivariable linear regression model. A P-value of less than 5% was considered to declare a significant association.

Results

The findings demonstrated that intention to practice solid waste management explained 86% of the variance explained by all predictors. The perceived behavioral control construct had the greatest impact on households’ behavioral intentions to comply with solid waste management practice (β = 0.16; CI (0.14, 0.18), followed by attitude (β = 0.15; CI (0.11, 0.21) and subjective norms (β = 0.12; CI (0.06, 0.17).

Conclusion

Our study also found that intention has a substantial influence on the behavior of solid waste management practices. Therefore, there is a need to enhance service utilization for solid waste management and to improve outdoor solid waste dropping behavior through door-to-door collection services by municipality. Furthermore, further longitudinal research should be done through intervention mapping.

A mixed-methods exploration of virtual reality as a tool to promote green exercise

The salutogenic effects of green exercise are widely recognised, yet many individuals do not engage in this health-related behaviour. Using a convergent mixed methods approach, this study explored the impact of experiencing nature through Virtual Reality (VR) on the decision-making process relating to green exercise. Three experimental trials were conducted (overall n = 136), in which healthy adults were exposed to different VR scenarios reproducing a virtual walk in an existing urban green area. Participants reported medium–high rating of intent to visit the location. Significant pre-to-post increments in future green exercise intention were observed after the VR exposure, though a significance difference was not achieved in comparison with a control condition. Qualitative analysis revealed the impact of the VR experience on behaviour regulation, and highlighted the pivotal role of anticipated emotional benefits. Despite scepticism, the VR experience was effective in arousing curiosity to explore natural environments, which was associated with environmental perceptions as well as nostalgic and socio-cultural perspectives.

Intention to reduce food waste: A study among Malaysians

Malaysia, also known as a food haven, is currently facing an excessive food waste problem which poses a threat to the environment. The objective of this research is to study the factors that affect the behavioral intention of Malaysians to reduce food waste. This study employs the Theory of Planned Behavior (TPB) and the Norm Activation Model (NAM) to better understand the behavioral intention of Malaysians toward reducing food waste. A cross-sectional study was conducted, using 352 self-administered survey questionnaires. Data collected were analyzed through PLS-SEM analysis. The results show that awareness of consequences (AC) and ascription of responsibility (AR) influence personal norms, while attitude, perceived behavioral control, and personal norms (PN) have significant effect on behavioral intention (BI) to reduce food waste. Furthermore, PN partially mediates the relationship between AC and BI as well as AR and BI. This study offers critical insights which will benefit the Malaysian Government, Non-Governmental Organizations (NGOs), and other related parties in recognizing factors influencing the intention to reduce food waste which can be adopted to develop practical solutions to curb food waste in Malaysia.Implications: This study offers critical insights to the Malaysian Government, non-governmental organizations (NGOs), and other related parties in recognizing factors influencing the intention to reduce food waste which can be adopted to develop practical solutions to curb food waste in Malaysia.

The effect of the visual exercise environment on the response to psychological stress: a pilot study

Background: Performing physical activity whilst exposed to nature can improve health. However, there is little evidence of its impact on stress outcomes. The aim of this study was to examine the influence of the visual exercise environment on the response to a psychosocial stressor. Methods: Eighteen participants were randomized to one of three conditions: i. nature; ii. built or; iii. control condition. Participants exercised for 30 min on a treadmill at 50% of their VO₂max whilst viewing a video of either a natural or built environment or a blank screen. Following the exercise, participants completed the Trier Social Stress Test (TSST), a standardized laboratory stressor. Salivary samples were collected before, during and after the TSST to calculate cortisol reactivity and recovery. Results: One-way ANOVA revealed a significant effect of viewing condition on cortisol reactivity [F _{(2, 11)} = 4.686, p = .034; n ² _p  = .460]; with significantly lower reactivity in the built compared to the nature condition (p = .027, d = 1.73). There was no effect of condition on cortisol recovery (p = .137; n ² _p = .257). Conclusions: In the context of the adverse health impact of lower (i.e., blunted) cortisol responding, these findings could indicate a negative impact of the built environment on stress responses.

Psychometric Properties of a Theory of Planned Behavior Questionnaire for Assessing the Midwives' Intention to Provide Planned Home Birth Services in Nigeria

We developed and psychometrically tested a Theory of Planned Behavior (TPB) questionnaire which focused on assessing the midwives' intention to provide planned home birth (PHB) services. This is a quantitative, cross-sectional survey, conducted among 226 midwives working in ten participating health facilities. The reliability and validity of the theoretical constructs were assessed. The Cronbach's alpha values were >0.8 for all scales, suggesting satisfactory internal consistency. Confirmatory factor analysis revealed sufficient convergent validity (the average variance extracted was >0.5 for each construct) and discriminant validity. The study gathered an evidence of the usefulness of TPB in the specific context of PHB.

MacIntyre T, Calogiuri G. Enable, Reconnect and Augment: A New ERA of Virtual Nature Research and Application

Being exposed to natural environments is associated with improved health and well-being, as these environments are believed to promote feelings of “being away” from everyday struggles, positive emotional reactions and stress reduction. Despite these positive effects, humanity is becoming increasingly more distanced from nature due to societal changes, such as increased urbanization and the reduced accessibility of natural environments. Technology is also partly to blame, as research suggests that people replace nature contact with increased screen time. In this cross-section between nature and technology, we find technological nature which is progressing towards a point where we may be capable of simulating exposure to real nature. Concerns have been raised regarding this technology, as it is feared it will replace real nature. However, research suggests that virtual nature may have a more positive impact on society than a mere replacement of real nature, and this review propose several areas where virtual nature may be a beneficial addition to actual nature (Enable), help people reconnect with the real natural world (Reconnect) and “boost” human-nature interactions (Augment). Based on the current research and theoretical framework, this review proposes guidelines for future research within these areas, with the aim of advancing the field by producing high quality research.

About Intentions to Donate for Sustainable Rural Development: An Exploratory Study

The Theory of Planned Behaviour (TPB) was used to investigate factors affecting the intention of citizens to donate money altruistically for sustainable rural development projects in Spain. To achieve this aim, individuals’ attitudes, subjective norms and perceived behavioural control have been considered; also, Azjen’s model was further extended to include additional elements: Moral norms, past behaviour, knowledge and some background factors. Respondents completed an online questionnaire assessing domains elaborated in the extended TPB model. Hierarchical multiple regression analysis revealed support for the model. Attitudes, injunctive norms, perceived behavioural control, moral norms, past behaviour, crowdfunding knowledge, age and employment condition were found to have positive and significant influence on intentions to donate. Theoretical and applied implications of the results are discussed, highlighting important considerations for public policy.
