General Collective Efficacy Scale

The General Collective Efficacy (CE) Scale is a 26-item measure of the mechanisms through which CE, defined as perceptions regarding a group's ability to execute actions related to a common goal, operate. The scale contains 6 factors related to CE: social response; social networks and personal agency; social attachment; common vision; associational participation; and community organization and leadership. In addition, CE scales for men and women were developed to allow for examinations of gender-specific mechanisms through which CE operates. The scale was originally developed within a sanitation and hygiene project in rural Ethiopia.

Scoring Procedures

Collective Efficacy (CE) factor scores may be calculated in two ways: as either average or average weighted scores. In either approach, higher factor scores represent higher levels of perceived behavioral control over the respective CE factors.

Average CE factor scores are calculated by summing responses for all items in each factor and dividing that sum by the number of items subsumed under that factor. This scoring is simpler however it assumes that all items have the same level of influence on the latent factor, which may not necessarily be the case. Therefore, a second approach was used in which one calculated the weighted average CE factor scores. Weights were applied to be equal to the item's initial factor loadings or loadings prior to generating an average score.
