BZUNECK, José Aloyseo; BORUCHOVITCH, Evely  and  RUFINI, Sueli Edi. Teachers' collective efficacy: Construct validity evidence of a questionnaire. Aval. psicol. [online]. 2014, vol.13, n.3, pp. 427-435. ISSN 1677-0471.

This paper describes the construction process and assessment of construct validity evidence of a Brazilian teachers’ collective efficacy instrument. The questionnaire is comprised of a set of twenty-two 5-point Likert scale items that contemplate situations and challenges within the daily routine at schools in which each teacher was required to mark how much he/she believes the teachers as a group were prepared to face said challenges successfully. The sample was composed of 229 teachers from diverse grade levels and geographic regions throughout Brazil. An analysis of principal components followed by a varimax rotation (assuming the actual value of 2.0 as a criterion), revealed a single factor structure which explained 51.26% of the items’ variance. Internal consistency of the scale, estimated by Cronbach’s alpha, was high (α=0.95). Further research and applications of the questionnaire in national educational studies are recommended.

Keywords : teachers; collective efficacy; measurement instrument development; factor analysis.
