Our research explored the factor structure and the reliability of the Italian version of the Emotion Regulation Checklist ERC; Shields, A.,& Cicchetti, D. (1997). Emotion regulation among school-age children: The development and validation of a new criterion Q-sort scale. Developmental Psychology, 33, 906-916, an instrument that has been widely adopted in studies using parents and/or teachers as informants. We carried out two studies evaluating the properties of the Italian ERC (ERC-I) when completed by parents and teachers, respectively. Study 1 participants were kindergarten and elementary school children for whom the ERC was completed by their mothers. Study 2 involved kindergarten and elementary school children for whom the ERC was completed by their teachers. The work confirms the two-factor structure of the instrument, supporting structure validity and the reliability of ERC.
