You would craft a thesis, that will probably end up being something along the lines of "Attachment theory is especially useful for X, Y, and Z in social work practice, but weak at A, B, and C." Then your essay would talk about the points you have listed, in the order you listed them, so that your thesis statement acts as sort of a miniature outline. That will likely give you a structure of
Intro
Summary of theory
Advantages
- Advantage I
- Advantage II
- Advantage III
Disadvantages
- Disadvantage I
- Disadvantage II
- Disadvantage III
Conclusion
That seems to be what the instructions are calling for, at any rate.
