Background:
This study focuses on the design, development, validation, and psychometric properties of the Children’s Environmental Affect Scale (CEAS). The following steps were taken in developing the CEAS.

Materials and methods:
A substantial review of literature on environmental affect and EL helped the researchers identify several scales and questionnaires that, in turn, help establish the item pool. The initial scale derived from this item pool was reviewed by the selected experts (n=17) and then pilot tested with 673 students in 4th -5th grades. These pilot data were subjected to Explanatory Factor Analysis (EFA) to reveal the dimensions underlying these pilot items. Later, the revised version of the scale was administrated to 2412 students in 5th grade as part of a national assessment. The data from this full study were used to validate the factorial structure observed in EFA through using Confirmatory Factor Analysis (CFA) procedures in AMOS.

Results:
The final version of the CEAS employs a Likert-type scale to measure 14 items that reflect three sub-scales; Willingness to take environmental action (5 items, α= .87), Environmental Attitudes (5 items, α= .82) and Environmental Sensitivity (4 items, α= .67).

Conclusions:
-
