The Peters et al.Delusions Inventory (PDI) was designed to measure delusional ideation in the normal population, using Present State Examination as a template.The multidimensionality of delusions incorporated by assessing measures distress, preoccupation, and conviction.Individual items were endorsed one four adults on average.No sex differences found, an inverse relationship with age obtained.Good internal consistency its concurrent validity confirmed percentages common variance three...
There is increasing evidence that in the general population there are schizotypal traits and symptoms can be measured psychometrically. Norms reported for a new 21-item version of Peters et al. Delusions Inventory (PDI; 1999b). The PDI, originally based on Present State Examination, incorporates multidimensionality delusions by including measures distress, preoccupation, conviction. A total 444 healthy individuals completed PDI two other questionnaires measuring florid social desirability....
To assess the reliability and validity of Southampton mindfulness questionnaire (SMQ), a 16-item measure mindful awareness distressing thoughts images.A total 256 people participated, comprising non-clinical community sample 134 (83 meditators 51 non-meditators) clinical 122 with current psychosis. concurrent validity, participants half (total 197 participants) completed attention scale (MAAS). Predicted links were assessed affect, 59 patients validated to link between intensity 'delusional'...
Objectives. Previous research into schizotypy has shown that certain groups of people have similar experiences to the positive symptoms schizophrenia but remain functioning members society, such as those with profound religious (Jackson & Fulford, 1997). Method. The focus present study was explore incidence delusional ideation in New Religious Movements (NRMs). Hare Krishnas and Druids were compared two control (non‐religious Christian), deluded, psychotic in‐patients on delusions...
Background Cognitive models propose that faulty appraisal of anomalous experiences is critical in developing psychosis, particularly delusions. A data gathering bias may be fundamental to abnormal Aims To examine whether there a people at high risk psychosis Method Individuals with an at-risk mental state ( n =35) were compared matched group healthy volunteers =23). Participants tested using modified version the ‘beads’ reasoning task different levels difficulty Results When demands high,...
Members of the general population were screened for delusion-proneness using Peters et al. Delusions Inventory (PDI). Two groups formed from participants who scored in upper and lower quartiles PDI compared on a probability judgment task Need Closure scale (NFC). The study investigated whether "jump-to-conclusions" (JTC) reasoning bias, characteristic deluded participants, could be found delusion-prone individuals. NFC was as motivational factor that may correlate with this bias. Evidence...
Individuals reporting persistent psychotic experiences (PEs) in the general population, but without a “need for care”, are unique group of particular importance identifying risk and protective factors psychosis. We compared people with PEs no care” (non‐clinical, N=92) patients diagnosed disorder (clinical, N=84) controls (N=83), terms their phenomenological, socio‐demographic psychological features. The 259 participants were recruited from one urban rural area UK, as part UNIQUE (Unusual...
Acting on command hallucinations in psychosis can have serious consequences for the individual and other people is a major cause of clinical public concern. No evidence-based treatments are available to reduce this risk behaviour. We therefore tested our new cognitive therapy challenge perceived power voices inflict harm voice hearer if commands not followed, thereby reducing hearer's motivation comply.In COMMAND, single-blind, randomised controlled trial, eligible participants from three...
The Psychotic Symptom Rating Scales (PSYRATS) is an instrument designed to quantify the severity of delusions and hallucinations typically used in research studies clinical settings focusing on people with psychosis schizophrenia. It comprised auditory (AHS) subscales (DS), but these do not necessarily reflect psychological constructs causing intercorrelation between clusters scale items. Identification important some contexts because item clustering may be caused by underlying etiological...
Background. Previous twin studies investigating the heritability of schizotypy have often had limited power and failed to measure disorganization/social anxiety component. Method. Seven hundred thirty-three female pairs, drawn from Institute Psychiatry Volunteer Twin Register, completed Oxford–Liverpool Inventory Feelings Experiences Peters et al . Delusions Inventory. Structural equation modelling was carried out on scores for MZ DZ pairs. Results. The best fitting models all scales...
Outcome measures for cognitive behavior therapy psychosis (CBTp) have been derived from pharmacological studies, focusing on symptom change rather than outcomes such as distress or fulfilment. This study presents the development and psychometric properties of a new outcome measure (CHoice In Cbt psychosEs [CHOICE]), which reflects more strongly aims CBTp priorities service users. Service users who had received participated in focus groups to discuss their priorities, using topic guide...
Given the variable response to cognitive-behavioral therapy (CBT) when added antipsychotic medication in psychosis and evidence for a role of pretherapy level frontal lobe-based cognitive function responsiveness CBT other disorders, this study examined whether brain activity associated with working memory neural network predicts clinical schizophrenia.Fifty-two outpatients stable on at least one distressing symptom schizophrenia willing receive addition their usual treatment 20 healthy...
The stigma and negative societal views attached to schizophrenia can make the diagnosis distressing. There is evidence that poor insight into symptoms of disorder need for treatment may reflect use denial as a coping style. However, relationships between other styles have seldom been investigated.We examined associations insight, distress number in 65 outpatients with (final n=57) cross-sectional study.We found (i) awareness problems correlated greater distress, (ii) 'preference positive...
Objectives Psychotic‐like anomalous experiences are not inherently distressing, nor do they inevitably lead to clinical conditions. However, distress is an important predictor of onset and relapse in psychosis, a primary indicator problematic mental health. This study aimed identify factors that predict across three groups with experiences. Design methods used cross‐sectional design. Participants ‘Diagnosed’ ( n = 35), ‘At Risk’ 20), ‘Undiagnosed’ 36) completed the Appraisals Anomalous...
Background Previous studies have suggested that beliefs about voices mediate the relationship between actual voice experience and behavioural affective response. Method We investigated power (omnipotence), intent (malevolence/benevolence) emotional response (resistance/engagement) using Beliefs About Voices Questionnaire – Revised (BAVQ-R) in 46 hearers. Distress was assessed a wide range of measures: voice-related distress, depression, anxiety, self-esteem suicidal ideation. Voice...
The Cognitive Biases Questionnaire for psychosis (CBQp) was developed to capture 5 cognitive distortions (jumping conclusions, intentionalising, catastrophising, emotional reasoning, and dichotomous thinking), which are considered important the pathogenesis of psychosis. Vignettes were adapted from Style Test (CST),1 relating "Anomalous Perceptions" "Threatening Events" themes. Scale structure, reliability, validity investigated in a group, CBQp scores compared with those depressed healthy...
Psychotic experiences (PEs) are common in the general population but do not necessarily reflect a risk status if they occur relative isolation or distressing. Emerging evidence suggests that PEs might be experienced as more benign for individuals from collectivistic low- and middle-income countries (LAMIC) compared with individualistic high-income (HIC). The aim of this study was to determine whether: (1) self-reported less distressing community samples LAMIC than HIC; (2) network is...
Environmental noise causes cognitive impairment, particularly in executive function and episodic memory domains, healthy populations. However, the possible moderating influences on this relationship are less clear. This study assessed 54 participants (24 men) a battery (measuring psychomotor speed, attention, function, working memory, verbal learning memory) under three (quiet, urban, social) conditions. IQ, subjective sensitivity, sleep, personality, paranoia, depression, anxiety, stress,...
