A voice that orders someone to hurt themselves or someone else is one of the highest-risk presentations a clinician working with psychosis will encounter. It is also one of the most likely to get managed as a risk to contain rather than treated as a symptom in its own right. For years the standard response was closer observation and medication, not therapy aimed at the belief.
Only two books cover this ground, and they’re two stages of one research programme rather than rival approaches. The first introduces a new model called Cognitive Therapy for Command Hallucinations and tests it on a small group of patients. The second comes years later, after a much larger trial confirmed the model works, and tackles the harder cases the first book didn’t cover. Together they give you both the theory behind treating command hallucinations directly and a realistic sense of how that plays out with difficult patients.

A Casebook of Cognitive Behaviour Therapy for Command Hallucinations: A Social Rank Theory Approach
Sarah Byrne, Max Birchwood, Peter Trower, and Alan Meaden, Routledge, 2006
This book introduces Cognitive Therapy for Command Hallucinations (CTCH), which is built on social rank theory. The theory holds that how much power someone attributes to a threatening voice, and how weak they feel by comparison, predicts whether they’ll obey it. Rather than treating the hallucination’s content as the target, the therapy goes after those power and rank beliefs directly. The reasoning is that a patient who no longer believes the voice is all-powerful has less reason to comply with it.
The book opens with two chapters making the theoretical case, then a manual chapter setting out the protocol from assessment through formulation to intervention. Seven named case chapters follow, each working through the protocol session by session with a real (anonymised) patient. Several of them were described as complex presentations. The final chapter reports the trial behind the model: a single-site, single-blind RCT of 38 patients, split between CTCH and treatment as usual and followed up at 6 and 12 months.
The trial this book reports on was small and single-site, and the authors are candid that no evidence-based treatment for command hallucinations existed before it. What it couldn’t yet show was whether the effect would hold at scale – that question is exactly what the companion volume below was built to answer.
Recommended for clinicians who want the theoretical rationale and the step-by-step manual, not just a summary of what the technique eventually proved.
Cognitive Therapy for Command Hallucinations: An Advanced Practical Companion
Alan Meaden, Nadine Keen, Robert Aston, Karen Barton, and Sandra Bucci, Routledge, 2013
This is the follow-up manual for clinicians who’ve run the basic CTCH protocol and hit its limits. These include patients who won’t engage, voices tangled up with persecutory delusions, and cases where the standard sequence of techniques simply doesn’t land. The book works through five further named cases and shows unsuccessful attempts alongside the successful ones, rather than presenting only wins. It also breaks the protocol into levels depending on how entrenched a patient’s beliefs about a voice’s power already are. This lets the therapist match the intensity of the intervention to how entrenched the belief already is.
Recommended for clinicians who’ve already worked through the Byrne casebook’s core manual and are now looking for the cases that didn’t go smoothly. This book assumes you know CTCH and need help with what happens when it doesn’t work as written.
