Tara is comparing different age groups at a single point in time, so this is a cross-sectional study. A longitudinal study would follow the same individuals over time and examine changes in anxiety levels within individuals over time. A sequential study would combine elements of both cross-sectional and longitudinal designs by studying different age groups at multiple points in time. An analogue study would use a sample that is not representative of the population of interest, such as using college students as participants.
