Abstract Purpose The purpose of this study was to identify the explanatory power of the affective, cognitive and evaluative aspects of identity with work teams in predicting team effectiveness, represented by the variables: satisfaction with the team, manager-assessed team performance and objective indicators of performance. Design/methodology/approach Data were collected from 131 work teams of a Brazilian public organization with units in all state capitals of the country. Work team identity scale, the work team satisfaction scale, the team performance scale and objective performance indicators collected based on the achievement of the goals set for the units that make up the organization were used. To test the predictive model, three regressions were conducted using the stepwise method. Findings Regression analysis results showed that the evaluative dimension explains about 6% of the performance assessment given by managers, whereas the affective dimension explains 63% of the satisfaction with work teams. No significant results were found for the objective performance indicators. Originality/value The observed findings demonstrate the pertinence of understanding the work team identity as a collective and multidimensional phenomenon, as well as the contribution of its different components in explaining variables that represent effectiveness.

Resumo O objetivo desse estudo é desenvolver e validar uma escada de identidade com equipes de trabalho composta pelas dimensões afetiva, cognitiva e avaliativa. Dois estudos foram conduzidos. O estudo 1 buscou evidências de validade para uma escala de identidade com equipes de trabalho. Os dados foram coletados em uma amostra de 364 pessoas. O estudo 2 verificou a estabilidade da solução fatorial encontrada no estudo 1. A amostra foi composta por 367 empregados de uma organização pública brasileira. A estrutura fatorial final compõe-se por 20 itens distribuídos em três fatores e capaz de explicar 65% da variância. Indicadores de consistência interna foram satisfatórios (0,79 < α < 0,94 para o Alpha de Cronbach e 0,52 < x < 0,75 para a média de correlações item-total). A escala desenvolvida pode ser considerada uma contribuição teórica e um avanço para a mensuração da identidade com equipes de trabalho.

Abstract The aim of this study is to develop and validate a scale of identity with work teams composed of affective, cognitive, and evaluative dimensions. Two studies were conducted. Study 1 sought evidence of validity for a scale of identity with work teams. Data were collected from a sample of 364 people. Study 2 verified the replicability of the factor solution found in Study 1. The sample consisted of 367 employees of a Brazilian public organization. The final factor structure consists of 20 items divided into three factors, capable of explaining 65% of the variance. Indicators of internal consistency were satisfactory (0.79 < α < 0.94 for Cronbach's Alpha and 0.52 < x < 0.75 for the item-total correlations mean). The scale developed can be considered a theoretical contribution and an advance for the measurement of identity with work teams.

Resumen El objetivo de este estudio fue desarrollar y verificar las evidencias de fiabilidad de una escala de identidad con el equipo de trabajo, compuesta por las dimensiones afectiva, cognitiva y evaluativa. Dos estudios fueron realizados. El primero busco evidencias de fiabilidad de la escala de identidad con los equipos de trabajo. Los datos fueron recogidos de una muestra de 364 personas. El estudio 2 se propuso verificar la replicabilidad de la solución factorial encontrada en el estudio 1. La muestra estuvo compuesta por las respuestas dadas por 367 empelados de una organización pública brasileña. La estructura factorial final se compuso de 20 ítems distribuidos en tres factores y fue capaz de explicar 65% de la varianza. Los indicadores de consistencia interna fueron satisfactorios (0,79 < α < 0,94 para Alpha de Cronbach y 0,52 < x < 0,75 para el valor medio de la correlación ítem-total). El desarrollo de la escala puede ser considerada una contribución teórica al campo, así como un avance en dirección de la medición de la identidad con equipos de trabajo.
