Modeling the Factors That Determine Sustainable Development Goal 12 in University Students
Abstract
:1. Introduction
2. Framework
- Sustainable Consumption Behavior (SUS BEH) refers to the responsible use of goods and services to minimize environmental impact and ensure the conservation of natural resources for current and future generations.
- Sustainable Consumption Habits (SUS HAB) refer to the practices individuals can adopt to lead more sustainable lifestyles and positively impact society. This includes actions such as consuming less, selecting products with lower environmental impacts and reducing the carbon footprint associated with everyday activities.
- Green Purchasing (GR PURCH) refers to the practice of buying products and services that have a lower impact on human health and the environment compared to similar options. For a purchase to be considered green, it must meet specific criteria that demonstrate a reduced environmental footprint. This concept is related to consumer trends and habits, such as a growing preference for organic products over conventional ones.
- Environmental Education and Information (ENV EDU) empowers individuals to explore environmental issues, engage in problem-solving, and take action to improve the environment. This process promotes a deeper understanding of environmental challenges and helps develop the skills necessary for making informed and responsible decisions. Key topics include awareness and sensitivity to environmental challenges, knowledge and understanding of environmental issues, attitudes that reflect concern for the environment, and motivation to enhance or preserve the environment.
- Environmental Influence (ENV INF) refers to various conditions in the surrounding environment, as well as structures and external sources such as friends, family, communities, and social or technological factors that can affect individual development.
- Social Environmental Pressure (SOC PR) refers to the different conditions or groups that can influence individual development by applying various forms of pressure. Cultural and social norms also establish expectations for how individuals should behave in different contexts. Additionally, media and social networks can exert significant pressure by setting behavioral standards related to the environment.
- Government Action (GOB AC) includes initiatives by local authorities aimed at fostering environmental stewardship among community members. These efforts seek to inspire community members to actively participate in the care of our shared environment.

- -
- RQ 8 (H5). Sustainable Habits correlate positively with Sustainable Behavior.
- -
- RQ 9 (H6). Green Purchase influences Sustainable Consumption Behavior.
3.4. Research Method
- -
- Indicator Reliability: Outer loading for each indicator should meet or exceed 0.70 (Lowry & Gaskin, 2014).
- -
- Internal Consistency Reliability: Assessed using Cronbach’s alpha (α) and Composite Reliability (CR), with a threshold of ≥ 0.70 for both (Hair et al., 1998).
- -
- Validity:
- Convergent Validity: Average variance extracted (AVE) should be ≥ 0.50 (Hair et al., 2017).
- Discriminant Validity: Verified by three methods:
- ○
- Fornell–Larcker criterion (Hair et al., 2017);
- ○
- Cross-loadings; (Hair et al., 1998);
- ○
- Heterotrait-monotrait ratio (HTMT) (Hair et al., 2017).
- -
- Check for collinearity issues (VIF < 5);
- -
- Evaluate the significance and relevance of the relations in the structural model (p < 0.05);
- -
- Analyze the R2 level (with thresholds of 0.190 for weak, 0.333 for moderate and 0.670 for substantial);
- -
- Assess Q2 values (should be over zero);
- -
- Check the model’s fit (SRMR ≤ 0.08; RMStheta ≤ 0.12).
4. Results
4.1. Measurement Model
- -
- Internal Consistency Reliability Tests
- -
- Discriminant Validity
4.2. Structural Model Validation
- -
- The Standardized Root Mean Square Residual (SRMR). In this study, the SRMR was 0.082, which is below the threshold of 0.10 recommended by (Lohmöller, 1989).
- -
- The Normed Fit Index (NFI), as proposed by (Chin & Newsted, 1999). Higher values close to 1 indicate a better fit, with values above 0.9 representing an acceptable fit level (Lohmöller, 1989; Hu & Bentler, 1999). Here, the NFI value was 0.658.
