Measuring Common Responses to Psychosis: Assessing the Psychometric Properties of a New Measure

Sarah Tully, Adrian Wells, Melissa Pyle, Jemma Hudson, Andrew Gumley, David Kingdon, Matthias Schwannauer, Douglas Turkington, Anthony P. Morrison Full Article  Abstract Responses to psychotic experiences are central to cognitive models of psychosis. The current study aimed to develop and validate a self-report measure of common responses to the experience of psychosis. This measure is needed as cognitive and behavioural responses are implicated in the maintenance of psychosis, but there is currently no measure that comprehensively assesses these maintaining factors. The Measure of Common Responses to psychosis (MCR) was developed and utilised in a sample of 487 participants who met criteria for treatment-resistant schizophrenia. Principal components analysis using data from 287 participants reduced the initial item pool of 31 items to 15 items with a three...

Interventions to improve the experience of caring for people with severe mental illness: A systematic review and meta-analysis

Udechuku A,  Mayo-Wilson E,  Harrison B,  Young N,  Woodhams P,  Shiers D,  Kuipers E,  Kendall T Full Article  Abstract BACKGROUND: Informal caregiving is an integral part of the care of people with severe mental illness, but the support needs of those providing such care are not often met. AIMS: To determine whether interventions provided to people caring for those with severe mental illness improve the experience of caring and reduce caregiver burden. METHOD: We conducted a systematic review and meta-analyses of randomised controlled trials (RCTs) of interventions delivered by health and social care services to informal carers (i.e. family or friends who provide support to someone with severe mental illness). RESULTS: Twenty-one RCTs with 1589 carers were included in the review. There was evidence suggesting that the carers' experience of care was improved at...

Promoting physical health for people with schizophrenia by reducing disparities in medical and dental care

Moore S, Shiers D, Daly B, Mitchell AJ, Gaughran F Full Article Abstract OBJECTIVE: Acquiring a diagnosis of schizophrenia reduces life expectancy for many reasons including poverty, difficulties in communication, side-effects of medication and access to care. This mortality gap is driven by natural deaths; cardiovascular disease is a major cause, but outcomes for people with severe mental illness are worse for many physical health conditions, including cancer, fractures and complications of surgery. We set out to examine the literature on disparities in medical and dental care experienced by people with schizophrenia and suggest possible approaches to improving health. METHOD: This narrative review used a targeted literature search to identify the literature on physical health disparities in schizophrenia. RESULTS: There is evidence of inequitable access to and/or uptake of physical...

Health inequalities and psychosis: time for action.

Shiers D1, Bradshaw T2, Campion J2. Full Article Abstract People with psychosis face a life-restricting and life-shortening epidemic of obesity, diabetes and cardiovascular disease. This can be predicted by the associated antecedent risk factors evident from early in psychosis, yet remain largely ignored. Greater coordination between primary care, secondary care and public health to systematically prevent and intervene earlier for these physical illnesses offers a realistic solution to reduce this health inequality....

Thematic associations between personal goals and clinical and non-clinical voices (auditory verbal hallucinations)

Filippo Varese, Sara J. Tai, Lydia Pearson & Warren Mansell Full Article Abstract The content of voices is often self-referent, and related to concerns or salient aspects of voice-hearers’ lives. Based on a cybernetic theory of cognition and behaviour known as Perceptual Control Theory (PCT), this study examined whether the content of voices is thematically linked to the more fundamental construct of goals, i.e. internal representations of desired and undesired states. Twenty-two clinical and 18 non-clinical voice-hearers completed self-report measures of personal goals and clinical interviews to gather qualitative descriptions of voice content. Participants’ interview transcripts were systematically contrasted with their reported goals to code instances of thematic correspondence between voice content and personal goals. The analysis revealed that 33 of the 40 participants (82.5%) reported voices that thematically...
