Cross-sectional and longitudinal research both have their advantages and disadvantages in studying how abuse in early childhood affects personality development in middle childhood, adolescence, and adulthood. In a cross-sectional research approach, people of different cohorts will simultaneously be observed at one point in time. Individuals from each of the three groups - middle childhood, adolescence, and adulthood - would be studied at the same time to see if there are any differences among the age groups in personality development as a result of early childhood abuse. A cross-sectional approach is both cost and time effective, as they are relatively inexpensive and take little time to conduct, meaning that there would a diminished chance …show more content…

However, using a longitudinal research design is time-consuming where many of the individuals may choose to drop out of the study, and can be rather expensive to conduct. Additionally, the data may become skewed if the individuals become accustomed to the repeated testing, as it may begin to affect the results. A longitudinal approach could also reflect time of measurement effects, where the age trends are due to the historical period that the data is collected in. This would mean that perhaps the personality development may not be as much affected by the abuse, but rather the historical context in which the individuals being studied grew up
