This study aimed to identify how the psychological characteristics of college students are reflected in understanding sustainable development goals (SDGs) by examining college students' psychological characteristics, including attitude, interests, motivations, and self-efficacy, through the Sustainable Development Goals Psychological Inventory (SDGPI). The relationships among SDGs attitude, SDGs interest, SDGs motivation, and SDGs self-efficacy were analyzed by Pearson product-moment correlation coefficients. In addition, the Mann-Whitney U test and Kruskal-Wallis one-way analysis of variance were used to explore the differences among the college student groups in terms of gender, grade, and major in relation to attitude and personal characteristics. Attitude scores based on regression analysis were used to predict college students' interest, motivation, and self-efficacy in relation to the SDGs. According to the results, (a) the college students considered the three most important SDGs to be good health and well-being (SDG 3) (49.72%), quality education (SDG 4) (41.39%), and no poverty (SDG 1) (32.22%), while the three least important SDGs were decent work and economic growth (SDG 8) (41.11%), partnerships for the goals (SDG 17) (38.06%), and response consumption and institutions (SDG 12) (30.83%); (b) the SDGPI had a high reliability, with a Cronbach's alpha of 0.942; (c) there was a significant positive correlation between attitude and the variables of interest, motivation, and self-efficacy; (d) differences in attitudes, interest, and motivation between men and women were distinct and women scored much higher in these three subscales than men; (e) attitude could explain significant variance in interest, motivation and self-efficacy. In addition, attitude, interest, and motivation could account for self-efficacy. This study supports the development of sustainability education (SE) at the college level by providing new insights into college students' psychological characteristics in relation to the SDGs.
