In line with traditional methods of scale construction, exploratory factor analysis was used to examine the homogeneity of the RSCS.
Exploratory factor analysis was conducted for each version of the RSCS separately in order to test whether the wording of items (either negatively or positively) had an effect on responses.
In order to ascertain the internal consistency of the RSCS, alpha coefficients were computed for each set of items loading on a factor.
All items were assigned to their hypothesized categories: the structure that was found with the confirmatory procedure (for both versions of the RSCS) was the same as that for the exploratory analysis conducted on the initial RSCS item pool.
Unlike Bolton's findings, the positive and negative wording of the item statements in the two versions of the RSCS did not define separate dimensions of self-concept.
The UL RSCS Program includes the considerable resources and compliance expertise of Underwriters Laboratories.
UL RSCS offers companies a password-protected database to help organizations manage their restricted substances test data.
UL utilizes an extensive global network of compliance engineers to visit RSCS customers twice each year.
The increasing environmental consciousness of nations will have a growing impact on manufacturers in the electronics and other industries," said Maxime Elbaz, general manager of the UL RSCS Program.
