A cross sectional study design was used to investigate the extent of chronic fatigue and the associated psychosocial exposures in a developing country. A cross sectional design may also make it difficult to establish what is cause and what is effect. Cross-sectional design aims to do the same thing, but rather than take a single group of the same ages and repeatedly test them as they grow older, this design takes a group of individual of different ages of developmental stages, and compare how the specific behavior is different from one age group to another. It is an affordable study method. Data on the primary outcome and psychosocial exposures … They may be either single cross-sectional (Figure 3.1).

Because these studies are essentially a “snapshot in time,” the most important concern with interpreting these studies is the inability to establish temporality, which leads to potential reverse causation. 1. Though design is a creative process it has economic consequences insofar as a product's shape, configuration and performance affect its marketability and its cost of production.

CROSS-SECTIONAL DESIGN: "Cross-sectional designs are sometimes thought to be unfair since, and considered to be useful only in instances that varying personality traits, ages, or amounts of life experience would not alter the validity of results." For example, a the control arm of a randomised trial may also be used as a cohort study; and the baseline measures of a cohort study may be used as a cross-sectional study. Cross‐sectional studies serve many purposes, and the cross‐sectional design is the most relevant design when assessing the prevalence of disease, attitudes and knowledge among patients and health personnel, in validation studies comparing, for example, different measurement instruments, and in reliability studies.

Cross sectional data is a part of the cross sectional study. What is Cross-Sectional Study? Hence, the two traditional research designs, longitudinal methods, which examine one group of people (such as people born in a given year), following and reexamining them at several points in time (such as in 2000, 2005, and 2010), and cross-sectional designs, which examine more than one group of people (of different ages) at one point in time.
