The given case of family participation is an example of correlational design  

A correlational study is a type of research strategy that looks at the relationships between two or more variables. Correlational studies are not experiments, so neither the variables nor the experimenter's control are altered.

In domains like psychology, biology, and sociology, correlational studies are typically recognised as research designs that attempt to ascertain whether or not there is a relationship between variables; they do not aim to ascertain how that relationship functions.

An association between two variables is called a correlation. They can be strong or weak, positive or negative. The two things might not always correlate. When using a correlational study design, no variables are within the researcher's direct control or manipulation.
