In the absence of more detailed information, it seems like you are interested in "structural equation models", or SEM. This is a broad class of multivariate methods that incorporate latent constructs into a regression framework, often specified through path diagrams similar to yours. (That said, you actually have most of the arrows pointed in the wrong direction for a true path diagram. This makes it look like your treatment groups are the outcomes!)
In general, you use a path diagram that captures the theoretical relationships between the variables and/or constructs of interest, using this to build a variance-covariance matrix. The "structural" component of the SEM model is what captures the basic regression relationships, while the "measurement" model embeds a factor analysis-type structure into the model to capture the latent variables (indeed, both regression and factor analysis can be viewed as a special case of a more general SEM).
Within SEM, there are a number of different types of model. You allude to multi-group analysis in your comment. There are many others, and it's impossible to give more specific recommendations without knowing more about what all of these variables represent. Three words of caution:
1) Sample size. Typically, you need relatively large sample sizes to reliably fit an SEM, especially one with multiple latent constructs. One of the costs of SEM being a flexible and powerful model is that they are complicated, and the number of parameters can grow pretty quickly. If your sample size is small (e.g. <50), you are likely better served approaching the problem in a different way.
2) Model identification. There is a lot of literature on this issue in the SEM world. There's a bit of a learning curve to understanding it, but generally it becomes intuitive pretty quick, and you can often diagnose many identification problems just by glancing at a path diagram when you get enough experience with it. For example, looking at your path diagram, I immediately see a potential identification issue with your two "Control" factors, which only have two indicators loaded onto each one. This is likely to be underidentified; that is you don't have enough information to reliably estimate those factors, without modifying the model in some way (e.g. allowing the two factors to be correlated with one another).
3) Non-normal dependent variables. While there is a decent amount of literature on the issue of integrating the generalized linear model framework into SEM, and several software packages that will fit some of these models, it is still a more complicated and difficult model. In my experience, the software on these can be finicky for anything but the most simple models.
