A team of researchers is investigating the effectiveness of a new cognitive-behavioural therapy (CBT) program designed to reduce anxiety symptoms in adults. They recruit 80 participants with diagnosed Generalised Anxiety Disorder (GAD) and randomly assign them to either a CBT group or a waitlist control group. Anxiety symptoms are measured using a self-report questionnaire before and after the 12-week program. The researchers find that the CBT group shows a statistically significant reduction in anxiety symptoms compared to the control group.
b. Outline three criteria that could be used to evaluate the validity of the researchers’ findings. For each criterion, explain how it applies to this specific study and what the researchers could do to address potential threats to validity.

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.

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.
