A Theoretical Model Is Developed Through Qualitative Research

A theoretical model is developed through qualitative research. The model explains family dynamics in relation to a new leukemia diagnosis for an infant. The researcher now tests the model, using structural equation modeling (SEM) . The final model contains family size, parental age, availability of extended family support, economic status, insurance status, and parental religious beliefs, as they predict anger, depression, effective decision-making, parental self-care, and cohesion. Which of the following are true, in relation to the model's variables?

A) Parental religious belief is an exogenous variable.
B) Leukemia diagnosis is an exogenous variable.
C) Extended family support is an endogenous variable.
D) Insurance status is an exogenous variable.
E) Effective decision-making is an endogenous variable.
F) Residual is NOT represented by any of the following: family size, parental age, availability of extended family support, economic status, and insurance status.
