The thing I've found most frustrating about the framing and discussion around these things in a clinical setting (in my limited experience, with people who were probably not trained specifically in these concepts) is that it's basically not allowed to say that your understanding doesn't fit on the "locus of control" spectrum (for example, if you reject mind-body dualism, without which the assumed concepts of "internal" and "external" are somewhat absurd). According to the worksheet, I must have some kind of one-dimensional "core belief" about the power of self versus environment. Some of the concepts and research around this seem promising, but in my experience as a patient/client, the practice leaves a lot to be desired. More broadly, I've been frustrated by a lot of the clinical psychology that focuses on highly stereotyped beliefs. Too much of it reads like just-so stories; Alice looks at Bob's behavior and then treats her own speculations about Bob's beliefs as though they're actual observations.
