Digital Drift.
Many people spend hours scrolling through social media on their smartphones before going to sleep. A psychologist wants to investigate whether there is a relationship between daily smartphone screen time (measured in minutes via a tracking app) and subjective sleep quality (measured using a new 10-item self-report questionnaire). They decide to use a correlational research design.
Explain how the researcher could assess the 'criterion validity' of the self-report questionnaire used to measure sleep quality in this study.
