Sustainability implies improvements in responsible behaviors such as recycling and energy saving. Yet, ecological behaviors cannot be improved only by attending to personal variables; focus must also be put on the collective variables. The main aim of this research was to analyze how individual variables (environmental values) and collective variables (collective efficacy for ecological behavior) interact to explain recycling (Study 1; 502 students of Spanish universities) and energy-saving behaviors (Study 2; 544 students of Ecuadorian universities). Participants completed an online questionnaire that reflected all the studied variables. Ecological behaviors were collected through frequency scales. The results of the moderated analyses performed with Process for SPSS confirmed the moderating effect of collective efficacy in the relationship that both preservation and appreciation established with recycling and energy-saving behavior alike. This moderating effect was also confirmed in the relationship that utilization developed with recycling, but not with energy saving. Thus, collective efficacy directly influences pro-environmental behavior, but also interacts with the personal values of individuals. Consequently, the results indicate the need to encourage collective efficacy for ecological behaviors of individuals, groups, collectives, and communities.

Understanding the variables that influence pro-environmental intentions is key to promoting pro-environmental actions. In this research, we analyze how the sense of responsibility toward climate change and implicit theories about climate change (ITCC) interact to condition individual pro-environmental intention. A total of 48 psychology students with a mean age of 19 years were randomly divided into two experimental groups and participated in a pretest–posttest experiment. The experimental manipulation consisted of reading a news extract regarding scientific research: one group was given information stating that climate change is still reversible, instilling incremental ITCC; the other group was given the opposite information, instilling static ITCC. The results of the one-way ANOVA (F = 4.206, p < .05) showed that people with incremental ITCC presented a greater intention to behave in a pro-environmental way than did individuals with static ITCC. Moreover, the moderating analysis showed that ITCC act as a moderating variable in the relationship between the sense of responsibility and pro-environmental behavioral intentions. The sense of responsibility predicted pro-environmental behavioral intentions when individuals held incremental ITCC (p < .01) but not when they held static ITCC (p = .901). This research emphasized the relevance of promoting incremental ITCC interventions in the environmental education field, as the sense of responsibility toward climate change is deterministic but not in itself enough to acquire the intention to behave in a pro-environmental way.

Connectedness to nature influences the well-being and health of individuals, communities, and the planet.Although there are different validated scales, none include the three fundamental aspects of any attitude: the affective, behavioural, and cognitive components. The study main objective was to develop and validate an integral tool, the ABC Connectedness to Nature scale (ABC-CNS), which would enable the measurement of the affective, behavioural, and cognitive aspects of this construct. The questionnaire was administrated to 1,375 students (878 Ecuadorian and 497 Spanish). Exploratory factor analysis retained the three expected factors. Confirmatory factor analyses confirmed a robust adjustment for the tridimensional structure, but cultural invariance was not attained: although the ABC-CNS is valid for both countries, the scores cannot be compared in both cultural contexts analysed. The pattern of relations with other psychological variables (proenvironmental values, appreciation and preservation of nature, and individual and classmates' proenvironmental behaviours) provided evidence of the structure and construct validity. The ABC-CNS scale is an integral, reliable, and short tool to measure connectedness to nature through the proposed dimensions. The tool is suitable for environmental professionals and researchers to assess individuals' connectedness to nature, a psychological variable that may affect individual mental health and proenvironmental behaviour.
