How do Individuals Respond to a Diagnosis of 3PD
How do Individuals Respond to a Diagnosis of 3PD
No studies have explored how patients with chronic dizziness react to a diagnosis of
 Persistent Postural Perceptual Dizziness (3PD) and their beliefs and representations of the
 diagnostic label. Investigating the experience of diagnostic labelling from the perspective
 of patients will allow clinicians to recognise whether this is a helpful term to adopt and
 ways to improve the clinical consultation.

 This is a qualitative study that will consist of semi-structured interviews with people with
 a new diagnosis of 3PD. The main objective of the study is to explore how patients react to
 this diagnostic label, what they understand about their diagnosis and how their own meanings
 affect their expectations and illness perceptions. Between 12-15 patients will be recruited
 from the balance clinic at Guy's Hospital, London, UK. The qualitative data will be analysed
 using thematic analysis which will draw on pragmatic interpretive descriptive methodology.
Semi-structured interviews will be conducted with patients, following a topic guide, which
 may be updated iteratively during the data collection period in response to ideas that may be
 generated. The topic guide explores key topics: (1) the patient's narrative; (2) the illness
 experience; (3) receiving the diagnosis; (4) their understanding of the 3PD label and
 beliefs; (5) expectations of recovery and treatment; (6) psychological and emotional factors;
 and (7) free comments. The interviews will be audio recorded and transcribed verbatim.

 Data will be analysed using inductive thematic analysis. Analysis will be conducted
 concurrently with data collection, allowing themes to be explored inductively as they emerge.
 Analysis will be performed by a multidisciplinary group consisting of a medical student,
 audio-vestibular physician and physiotherapist.

 Analysis will be conducted with the aid of the latest version of computer software NVIVO for
 Windows. The medical student will lead the analysis, generating the initial codes which will
 then be discussed in data analysis meetings held regularly over the data collection and
 analysis period until the group are happy with the coding and themes generated. Data
 collection and analysis will be approached with critical reflexivity in order to reduce the
 risk of bias. The team will ensure the analysis is grounded in the data.

 Patients will be included if they meet the diagnostic criteria for Persistent Postural
 Perceptual Dizziness (3PD). Patients will be excluded if they;

 -  Do not speak English or have special communication needs.

 -  Have cognitive impairment.

 -  Have acute severe psychiatric disorder (e.g. psychosis).

 The investigators plan to interview a minimum of 12 participants and review the need for
 further interviews up to 15 participants if there are new themes developing (i.e. if the
 investigators have not reached data 'saturation').
Inclusion Criteria:

 • Patients who attend the balance clinic at Guy's Hospital and are diagnosed with
 Persistent Postural Perceptual Dizziness (3PD).

 Exclusion Criteria:

 -  Patients who do not speak English or have special communication needs.

 -  Patients with cognitive impairment.

 -  Patients with acute severe psychiatric disorder (e.g. psychosis)
