This study provides an overview of components of teacher identity that are found in quantitative measurement instruments; and reports on the psychometric quality of these measurement in- struments. Our search included studies that assessed components of teacher identity published in English-written, peer-reviewed articles between 2000 and 2018. We analyzed a total of 59 components in 20 studies. After we categorized the components on the basis of a substantive analysis, six main domains of teacher identity became apparent: Self-image, Motivation, Commitment, Self-efficacy, Task perception, and Job satisfaction. Whereas the overall psycho- metric properties of the measurement instruments used in the different studies were acceptable to good, our systematic overview revealed several conceptual and methodological issues that need to be resolved. The results may contribute to the further operationalization of the complex construct of teacher identity.
This longitudinal study investigated reciprocal associations among various professional identity tensions and Dutch primary student teachers’ teacher identity. Students (N = 201, 82.9% female) completed the professional identity tensions scale and the teacher identity measurement scale across three waves. Random intercept cross-lagged panel models showed that five out of nine investigated professional identity tensions were negatively associated with teacher identity at the inter-individual level. At the intra-individual level, no significant cross-lagged relationships were detected. Our findings imply that the development of professional identity tensions and teacher identity are not automatically interrelated and should, therefore, be both explicitly addressed in teacher education.
The purpose of this study was to develop and evaluate an interprofessional identity measurement instrument based on Extended Professional Identity Theory (EPIT). The latter states that interprofessional identity is a social identity superordinate to a professional identity consisting of three interrelated interprofessional identity characteristics: belonging, commitment and beliefs. Scale development was based on five stages: 1) construct clarification, 2) item pool generation, 3) review of initial item pool, 4) shortening scale length (EFA to determine top four highest factor loadings per subscale; 97 dental and dental hygiene students), and 5) cross-validation and construct validity confirmation (CFA; 152 students and 48 teachers from six curricula). Explained variance of the EPIS was 65%. Internal consistency of the subscales was 0.79, 0.81 and 0.80 respectively and 0.89 of the overall scale. CFA confirmed three-dimensionality as theorized by EPIT. Several goodness-of-fit indexes showed positive results: CFI = 0.968 > 0.90, RMSEA = 0.039 < 0.05, and SRMR = 0.056 ≤ 0.08. The factor loadings of the CFA ranged from 0.58 to 0.80 and factors were interrelated. The Extended Professional Identity Scale (EPIS) is a 12-item measurement instrument with high explained variance, high internal consistency and high construct validity with strong evidence for three-dimensionality.
