If a self-report scale has high reliability and validity in group research, we can assume it will have equally high reliability and validity in single-case experiments.

While high reliability and validity in group research is a positive indicator for the quality of a self-report scale, it does not guarantee the same level of reliability and validity in single-case experiments, which require a different type of analysis and interpretation. Therefore, we cannot assume that the scale will perform equally well in both types of research designs.
