Abstract:This study focused on examining the reliability and convergent validity of the measurement instrument “Affect Grid” in ESM research. 19 participants answered six Affect Grids a day, for seven days. Previously, they filled out the neuroticism scale of the short form Eysenck Personality Questionnaire (EPQ-S). To assess reliability, a stability analysis was conducted. Additionally, participants’ neuroticism scores were compared to mean Valence scores, in order to assess the convergent validity.The stability analysis revealed no fixed effect for time, and correlation analyses revealed significant results for the stability of mean Valence and Arousal scores. In the validity analyses, neuroticism was found to be negatively correlated to Valence. Overall, this research is one of the first on the reliability and validity of the Affect Grid. Besides the limited sample size, the findings suggest that the Affect Grid is a reliable measurement tool. In combination with the evidence for convergent validity, the Affect Grid is recommended to be used in future ESM research.
