A researcher is investigating the effect of a new relaxation technique on reducing test anxiety in VCE students. They use a self-report questionnaire to measure anxiety levels before and after the intervention. To ensure the measurement validity of the questionnaire, what would be the MOST important step for the researcher to take?
Administer the questionnaire to a large sample of VCE students to increase statistical power.
Compare the questionnaire results with another established and validated measure of test anxiety.
Ensure that the questionnaire is administered in a quiet and comfortable environment to minimize extraneous variables.
Calculate the internal consistency of the questionnaire items to ensure they are measuring the same construct.

In this unit students explore the demand for sleep and the influences of sleep on mental wellbeing. They consider how changes to a person’s sleep-wake cycle can affect psychological functioning. Students explore the concept of mental wellbeing, including social and emotional wellbeing as a multidimensional and holistic framework. They apply a biopsychosocial approach to specific phobia, exploring how biological, psychological and social factors are involved in its development and management. A student-designed scientific investigation involving the generation of primary data related to mental processes and mental wellbeing is undertaken in either Unit 3 or Unit 4 or across both Units 3 and 4, and is assessed in Outcome 3 of this unit.
Students undertake a student-designed scientific investigation in either Unit 3 or Unit 4, or across both Units 3 and 4, related to mental processes and mental wellbeing. The investigation involves the generation of primary quantitative data. Students apply key science skills to develop and test a research question, gather and analyse data, and communicate findings in a structured scientific poster. A logbook is maintained for authentication and assessment purposes.
