If you only need the buying answer: the eBook route is the cheapest option in this snapshot, but the current paperback is still below the sampled marketplace and used-print comparators. That makes this another case where short-term digital wins on price, while print still has a reasonable case if you want a keepable reference.

What this book actually teaches
The Science and Treatment of Psychological Disorders is a psychology text about psychopathology, treatment models, research evidence, and clinical comparison across disorders. The book matters because it helps readers connect scientific understanding to treatment reasoning rather than treating disorders as isolated summary chapters.
That gives the book some lasting value for psychology and counseling students, especially if abnormal psychology and treatment frameworks will reappear later. But that later value has to be weighed against the lower-cost eBook route in the current market.
When print is still worth buying
The honest cheapest route is the eBook. But the current paperback remains lower than the sampled marketplace and used-print options, so it is not a bad ownership price. The print decision makes more sense when you expect the book to remain useful after the course rather than just during it.
I would lean toward the eBook for the lowest-cost short-term access. I would lean toward print for readers who want a keepable psychological-disorders reference to return to later in psychology or counseling training.
