How I See Me-A Meta-Analysis Investigating the Association Between Identities and Pro-environmental Behaviour

When a #Selfie is Healthy: How Self-Persuasion Through User-Generated Content Influences Intentions

As user-generated content (UGC) increasingly shapes the digital communication landscape, this study explored how message creators may persuade themselves to engage in healthier activities. In an online experiment, participants (N = 404) were asked to select a topic (healthy eating or exercising) and view a screenshot from a fictitious health organization. Afterward, participants were randomly assigned (based on topic) to: (a) create a video, (b) watch a video, or (c) a control group, and answer a questionnaire. A mediation analysis showed that message-creation was associated with more positive attitudes, self-identity, and self-efficacy. In turn, these variables were associated with greater intentions to adopt healthy practices. Merely watching a video (or doing nothing) was less influential. The data suggest specific mechanisms by which self-persuasion may affect behavior in digital health contexts, particularly via self-efficacy. Results also suggest recommendations for practitioners to leverage the persuasive influence of UGC in health-promotion campaigns.

Social targeting conservation subsidies in the Western Lake Erie Basin

Achieving public conservation objectives often requires voluntary conservation on private land. However, some landowners are reluctant to participate in voluntary conservation programs, even when offered financial incentives. Heterogeneity in willingness to participate suggests that policymakers can improve conservation outcomes by strategically targeting subsidy program outreach, messaging, and design to landowners who are more likely to enroll, which we call "social targeting." This paper informs social targeting a subsidy to farmers to construct wetlands in the Western Lake Erie Basin in the United States. We use a discrete choice survey and a latent class model to identify preference heterogeneity and farmer attributes associated with willingness to construct wetlands. Willing respondents prefer larger projects, but fully subsidized construction is vital for participation. Simulation results highlight that even the most willing farmers are unlikely to install a wetland if construction is not fully subsidized. Policy practitioners should target outreach to younger farmers and larger farms. Outreach strategies should focus on private benefits from the wetland, such as aesthetic values and hunting opportunities, highlight farmer responsibility for Lake Erie water quality, and promote positive social norms surrounding wetland construction.

Pro-environmental behavior to improve the quality of life with social value orientation as moderator: findings from Indonesia

Environmental degradation endangers human life. Future generations will be at risk if the necessary impact is not immediately addressed. Addressing environmental issues and enhancing quality-of-life (QoL) require pro-environmental behavior. This study aimed to examine the moderating role of social-value-orientation (SVO) in the association between pro-environmental behavior and QoL. Conducting in Indonesia and involving 402 students i.e., 303 female-students (Mages = 20.48 years, SD = 1.42) and 99 male-students (Mages = 20.49 years, SD = 1.42), this study used General Ecological Behavior Scale (α = 0.83), the WHOQOL-BREF (α = 0.87), and the triple-dominance of SVO. JASP 0.17.2.1 was performed to analyse data namely descriptive statistics and testing the moderating effect. The results showed that pro-environmental behavior and SVO predicted QoL (R2 = 0.247, F(3.398) = 45.533, p = 0.001), SVO moderated the association between pro-environmental behavior and QoL significantly (β = 0.141, p = 0.002). These findings have important implications for the sustainable behavior's promotion and the QoL's improvement.

Proenvironmental self identity as a moderator of psychosocial predictors in the purchase of sustainable clothing

Previous research investigated the impact of psychosocial predictors (e.g. attitude, social and moral norm, perceived behavioral control, intention) on sustainable clothing purchasing. To date, no studies considered whether proenvironmental self-identity moderates the effects of these predictors on behavior. In this study, we adopted an intrapersonal approach and a longitudinal design to assess the moderating role of proenvironmental self-identity in predicting intentions and behaviors, considering gender differences. 250 participants completed an initial questionnaire on the predictors of three sustainable clothing purchasing. A month later, they filled out a second questionnaire to self-assess these behaviors. The results showed that social and internalized norms (moral norms) were notably influential of participants' intentions. Affective attitude influenced behavior positively, while cognitive attitude had a negative influence. When considering the moderating role of proenvironmental self-identity, significant gender differences emerged. Women with a weak proenvironmental self-identity expressed a higher intention to purchase sustainable clothing when they had high affective attitudes and descriptive norm but low cognitive attitudes. Women with a strong proenvironmental self-identity intended to purchase sustainable clothing when they had high moral norms and cognitive attitudes but low descriptive norm. Man with a weak proenvironmental self-identity and high positive affective attitude increased their future SCP.

Soft plastic fishing lures as a potential source of chemical pollution - Chemical analyses, toxicological relevance, and anglers' perspectives

Soft plastic lures (SPLs) are commonly used artificial lures in recreational angling. Anglers regularly lose SPLs while fishing and there is little knowledge about the environmental impacts of lost SPLs. As with other plastic items, SPLs contain phthalates and other persistent additives that may leach into water. In this study, 16 randomly chosen SPLs of common models were analyzed for the leaching of persistent, water-soluble plastic additives, including phthalates. The estrogenicity of sample extracts from a subsample of 10 SPLs was assessed using luciferase reporter gene bioassays. Over a period of 61 days, 10 of the 16 SPLs leached the targeted phthalates dimethyl phthalate (DMP), diethyl phthalate (DEP), benzyl butyl phthalate (BBP) and di-n-butyl phthalate (DnBP) at median detectable concentrations ranging from 10 ng/g sample BBP to a median of 1001 ng/g DMP as well as 45 persistent, mobile, and toxic (PMT) plastic additives. DEP was detected most frequently in 8 SPLs, followed by BBP (2 SPLs), DMP (2 SPLs) and DnBP (1 SPL). The extract from one SPL with comparatively low phthalate and PMT plastic additive levels was active in the bioassay, indicating high endocrine-disruptive potential, presumably due to unknown additives that were not among the target substances of the methodology used in this study. The study was supplemented by a mail survey among anglers, in which attitudes of anglers towards SPLs were investigated. The survey indicated that SPL loss is a common event during angling. Most participants were concerned about potential ecological impacts of SPLs, wanted the ingredients of SPLs to be labelled and supported legal restrictions concerning toxic ingredients of SPLs. The study shows that SPLs are a potential source of environmental pollution, may pose human health risks and need further investigation, considering the frequent use of SPLs in recreational angling.

Exploring the role of identity in pro-environmental behavior: cultural and educational influences on younger generations

It is of paramount importance to gain an understanding of pro-environmental behavior if we are to successfully tackle the climate crisis. The existing body of research provides evidence that identity influences pro-environmental behavior. However, such research is often over-generalised and researchers are challenged to conduct robust analyses with regard to specific local, cultural and educational factors. The present study aims to investigate whether personal or social identity has a distinct effect on three different dimensions of pro-environmental behavior, using the principles of self-categorisation theory. Additionally, the study seeks to determine whether one of these two factors, the individual or the social factor, is predominant over the other. The study group consisted of cooperative students in Germany, typically a group with high professional ambitions. The data was collected in a cross-sectional survey with a total of 568 cooperative students from academic disciplines in engineering and economics. The reliability of the scales is satisfactory (ω = 0.76-0.88), and the hypotheses are tested by estimating structural equation models. Our research demonstrates that while social identity exerts a stronger influence on activist behavior than personal identity, personal identity has a more pronounced effect on consumer behavior than social identity. Nevertheless, no general statement can be made regarding the relative strength of the effects of personal and social identity on pro-environmental behavior dimensions.

Influence of Appeal Type and Message Framing on Residents' Intent to Engage in Pro-Environmental Behavior

In this intervention study, we examined the effects and psychological processes of different types of messaging intended to promote waste-separation behavior on the intent of residents to separate household waste and to engage in other pro-environmental behaviors (PEBs). Based on three studies (one survey with 76 residents and two experiments with 446 residents) in China, our results revealed that environmental appeals increased residents' intent to separate waste and engage in other PEBs, whereas monetary incentives had no effect. Although the main effects of the framing of messages on the intent to separate waste and other PEBs were not significant, we found an interactive effect of appeal type and message framing. When matched with loss framing, an environmental appeal indirectly generated a stronger positive impact by stimulating an individual's environmental risk perception. When monetary incentives matched with loss framing, individual pro-environmental identity weakened, thereby inhibiting the positive impact on intent to separate waste. With this study, we provide important theoretical support for the selection and optimization of waste-separation intervention strategies and guidance for persuading residents to engage in more PEBs.

A safe and just operating space for human identity: a systems perspective

A safe and just operating space for socioecological systems is a powerful bridging concept in sustainability science. It integrates biophysical earth-system tipping points (ie, thresholds at which small changes can lead to amplifying effects) with social science considerations of distributional equity and justice. Often neglected, however, are the multiple feedback loops between self-identity and planetary boundaries. Environmental degradation can reduce self-identification with nature, leading to decreased pro-environmental behaviours and decreased cooperation with out-groups, further increasing the likelihood of transgressing planetary boundaries. This vicious cycle competes with a virtuous one, where improving environmental quality enhances the integration of nature into self-identity and improves health, thereby facilitating prosocial and pro-environmental behaviour. These behavioural changes can also cascade up to influence social and economic institutions. Given a possible minimum degree of individual self-care to maintain health and prosperity, there would seem to exist an analogous safe and just operating space for self-identity, for which system stewardship for planetary health is crucial.

What Factors Affect Farmers' Levels of Domestic Waste Sorting Behavior? A Case Study from Shaanxi Province, China

Waste sorting is a key element for solving the current predicament of rural waste management. In the pilot areas of China, farmers' domestic waste sorting behavior (DWSB) varies significantly, whereas there are few studies exploring the mechanism of its formation. To fill this research gap, this study constructs a research model of the internal logic of farmers' waste sorting levels (i.e., no sorting; sorting recyclable waste; sorting recyclable and kitchen waste; and sorting recyclable, kitchen, harmful, and other waste) by considering circumstantial constraints (social norms in external factors) and psychological behavioral antecedents (personal norms and group identity in internal factors). Based on pilot survey data from farmers in Shaanxi Province, China, the results of the ordered logit model indicate that social norms and personal norms were the most significant predictors of the level of DWSB, while group identity was found to have no significant influence. Furthermore, the results of the grouping regression analysis showed that personal norms had a positive moderating effect on the relationship between social norms and farmers' DWSB. Therefore, a more positive social atmosphere, better education, and personal environmental moral responsibility for domestic waste sorting should be established to enhance their levels of waste sorting behavior.

Envy and Environmental Decision Making: The Mediating Role of Self-Control

Emotions have strong impacts on decision making, yet research on the association between social interpersonal emotion and environmental decisions is limited. The present study uses experimental manipulation and cross-sectional investigation to examine how envy state and personality trait envy influence environmental actions. In Study 1, participants were manipulated to elicit benign and malicious envy, and it was found that benign envy acts as an antecedent of pro-environmental behavior, while malicious envy could contribute to behavior harmful to the environment. Study 2 replicated the results of Study 1 and examined the mediator of self-control through a correlational study. Consequently, people who are high in malicious envy tend to engage in more environmentally harmful activities rather than living a sustainable life, while dispositional benign envy could significantly predict pro-environmental behavior. Moreover, the link between dispositional malicious envy and environmental behavior can be explained by trait self-control, while the mediating effect was silent in dispositional benign envy. The findings shed new light on the impact of social interpersonal emotion on making environmental decisions and its related psychological mechanisms.

Attitudes, Habits, and Behavior Change

Efforts to guide peoples' behavior toward environmental sustainability, good health, or new products have emphasized informational and attitude change strategies. There is evidence that changing attitudes leads to changes in behavior, yet this approach takes insufficient account of the nature and operation of habits, which form boundary conditions for attitude-directed interventions. Integration of research on attitudes and habits might enable investigators to identify when and how behavior change strategies will be most effective. How might attitudinally driven behavior change be consolidated into lasting habits? How do habits protect the individual against the vicissitudes of attitudes and temptations and promote goal achievement? How might attitudinal approaches aiming to change habits be improved by capitalizing on habit discontinuities and strategic planning? When and how might changing or creating habit architecture shape habits directly? A systematic approach to these questions might help move behavior change efforts from attitude change strategies to habit change strategies.
