The key aspects of this model are that the person appraises a VH as a threat to their physical or psychological wellbeing (Gauntlett-Gilbert and Kuipers, Reference Gauntlett-Gilbert and Kuipers2003, Reference Gauntlett-Gilbert and Kuipers2005), which understandably leads to fear or anxiety, and in turn leads to the use of safety seeking behaviours (such as avoidance and escape) to prevent the feared outcome. Whilst interesting as case studies, there is little in the reports to show that the VH specifically were targeted in treatment, and further evidence is required before it is possible to conclude that there is evidence of effective treatment for distressing VH.Ĭollerton and Dudley ( Reference Collerton and Dudley2004) adapted the cognitive model of distressing auditory hallucinations (AH) (Morrison, Reference Morrison2001) to help understand and treat distressing VH. There are a few case reports using cognitive behavioural therapy for psychosis (CBTp) (Callcott, Dudley, Standardt, Freeston and Turkington, Reference Callcott, Dudley, Standardt, Freeston, Turkington, Hagen, Turkington, Berge and Grawe2010 Hutton, Morrison and Taylor, Reference Hutton, Morrison and Taylor2012 O'Brien and Johns, Reference O'Brien and Johns2013). However, there is an absence of evidence of specific benefit of medication for VH (Collerton, Mossimann and Perry, Reference Collerton, Mosimann and Perry2015) or for psychological therapies (Waters et al., Reference Waters, Collerton, Jardri, Pins, Dudley and Blom2014). Given the prevalence, distress and impact of VH there is a need for effective treatments. The presence of VH is linked to increased disability and greater likelihood of in-patient status (Meuser, Bellack and Brady, Reference Mueser, Bellack and Brady1990 Waters et al., Reference Waters, Collerton, Jardri, Pins, Dudley and Blom2014). Visual hallucinations (VH) are relatively common, with around 27% of individuals with a diagnosis of schizophrenia (Waters et al., Reference Waters, Collerton, Jardri, Pins, Dudley and Blom2014) reporting VH. Attempts should also be made to replicate across therapists and centres. Further research should consider alternative methods of capturing behavioural change. This study replicates and extends the findings in showing potential value of CBT VH. Change was not evident on the standardized measures. Changes in frequency of VH were reported in two cases. Formal visual analysis of the data supported by statistical analysis indicated significant changes for appraisal and affect, with replication across three participants. Standardized measures were completed at each phase change. Participants used daily diary measures to record appraisals, affect, and behaviours related to the distressing VH. A multiple-baseline experimental single-case design methodology was used with five participants who received a CBT VH treatment package. Hence, this study aimed to measure change in appraisal, affect, and behaviour as a consequence of CBT VH, to improve understanding of the process of change. Preliminary research applying interventions to a novel presenting issue are enhanced by utilizing designs that allow strong inferences to be made about the effect of the intervention. There has been limited application of cognitive behavioural therapy (CBT) to the treatment of distressing visual hallucinations (VH) in people with psychosis.
