1987	Corral, Garibaldi & Encinas	They found in an exploratory study that the use of the shower was the main activity of domestic water consumption. In contrast, the use of the refrigerant was the domestic device with less frequency of use.
1992	Corral & Obregón	They carried out a systematic review of the variables included in the models of pro-environmental behavior. They measured the distance between the residence and the recycling depot, the environmental competencies, the styles and the ecological reasons as the determinants of pro-environmental behavior.
2000	Corral & Zaragoza	They demonstrated through a system of structural equations, four dimensions of recycling behavior, which was determined by the reasons for reuse. In this model, the size of the house and economic status influenced the behavior. However, beliefs through motives influenced reuse behavior. The authors established significant differences between men and women with respect to their knowledge and beliefs about product reuse and recycling.
2000	Hernández et al.	They made known a difference between proportions of non-parametric data, six categories: image and institutional identity, physical and built environment, solid waste, hazardous waste, electric power management and environmental training. Years later, the image of the campus, solid waste and environmental training remained the main problems.
2001	Acosta & Montero	They demonstrated significant associations between responsible environmental behavior, locus of control, knowledge of environmental action, environmental skills and cognitive coping styles related to denial and acceptance of environmental deterioration. As the values of one variable increased, the values of the other variable increased. Acosta and Montero proved that responsible environmental behavior is associated (r = 0.45; p < 0.05) with the skills and knowledge index of environmental action.
2001	Oceja & Jiménez	They evaluated a group of standards, analyzed their degree of compliance and established their classification. They showed that the typology is relevant based on three criteria: personal agreement, formal sanction and social disapproval. They determined differences between norms (legitimate laws and prescriptions are fulfilled more than illegitimate laws and convictions) using the criterion of informed and perceived compliance. And they revealed significant differences between attitudes towards each type of norm.
2002	Guevara & Rodríguez	They proved the tendency of residents of the City of Puebla to respond positively and homogeneously to garbage separation and collection services.
2002	Negrón, Arias & Delbrey	They showed significant differences between men and women regarding the change of their knowledge, after information relative to their knowledge about their health and the environment.
2003	Corral	Revealed through a structural model, the incidence of domestic utensils in water consumption. In this model, the reasons, scarcity and skills, had a negative effect on water consumption.
2003	Frías, López & Díaz	They demonstrated the indirect effect of the macrosystem on antisocial behavior through the microsystem. In the structural model, the exosystem had three indicators and the microsystem with five manifest variables.
2004	Bustos, Flores & Andrade	They argued the direct, positive and significant relationship between two behavioral variables pro-environmental: wash of bathrooms with personal hygiene (r = 0.17; p < 0.01), toilet of teeth with personal bath (r = 0.18; p < 0.01).
2004	Corral & Pinheiro	They established six dimensions of sustainable behavior: austerity, anticipation, altruism, effectiveness, deliberation and saving. They demonstrated positive and significant associations between the dimensions. Later, in a structural model, they proved the reflectivity of the sustainable behavior around the six dimensions referred to.
2004	Corral, Fraijo & Tapia	They revealed four dimensions of water consumption related to the use of basins, showers, irrigation and cleaning. Later they established, through a structural model, the incidence of ecological and utilitarian beliefs in water consumption. Both beliefs correlated negatively.
2004	Urbina	He showed that pollution and scarcity of water are perceived by experts and non-experts as risks.
2005	Aguilar & Valencia	Established through a structural model, the indirect effect of attitude, past behavior, control and personal norm on pro-environmental behavior through intention. In this structure, past behavior was the main determinant of ecological behavior.
2005	Fraj & Martínez	They found the moderating effect of environmental knowledge on the causal relationship between affective, verbal and real commitment. To the extent that environmental knowledge was minimal, the causal link and the percentage of variance were low. In contrast, when the level of environmental knowledge was specialized, the causal relationships and the variance explained increased significantly.
