“…Further studies should consider the variability between classrooms and take the nested structure of the data into account. In addition, future research might include the assessment of individual (e.g., temperament, anxiety; see Solomon, O'Toole, Hong, & Dennis, ) and environmental variables (e.g., quality of teacher–student interactions, presence of aggressive behaviours within the class; see Cassidy, King, Wang, Lower, & Kintner‐Duffy, ) that may enter the equation. A second limitation is related to the measure of classroom climate used on this study, which not only assesses the emotional component of the environment, but also covers physical and managing aspects of the classroom.…”
