Problem:
In the fields of psychology and counseling, where several variables are involved, multivariate models are crucial. A study can examine several variables simultaneously and comprehend their relationships by using a multivariate model. This is advantageous since it produces findings that are more correct. The requirement for a sizable sample size is a major drawback of multivariate models. According to Gama et al. (2021), their study had limitations. According to Gama et al. (2021), recall bias may have resulted from the retrospective design of the cross-sectional study. Only those who reported an index event that happened after childhood were included in the study. Participants were asked to report PTSD symptoms depending on their most severe experience. Additionally, the results may have been overstated due to the sample's preponderance of female participants. According to Giacomucci et al. (2025), there were difficulties in another study as well. According to the study, there was no control group, no follow-up assessments, and the treatment group was not assigned at random. Although they are challenging to incorporate into a naturalistic treatment program, each of these could improve the research design and validity of the study outcomes. Need Assignment Help?
