The impact of Patient and Public Involvement in the SlowMo study
BACKGROUND: The SlowMo study demonstrated the effects of SlowMo, an eight-session digitally supported reasoning intervention, on paranoia in a large-scale randomized-controlled trial with 362 participants with schizophrenia-spectrum psychosis. AIM: The current evaluation aimed to investigate the impact of Patient and Public Involvement (PPI) in the SlowMo study. METHOD: PPI members were six women and three men from Sussex, Oxford and London with …
Effect of initiating drug treatment on the risk of drug-related poisoning death and acquisitive crime among offending heroin users
For heroin-using offenders, initial contact with treatment services does not appear to reduce the likelihood of a future acquisitive offence
Modeling bivariate change in individual differences
A number of structural equation models have been developed to examine change in 1 variable or the longitudinal association between 2 variables. The most common of these are the latent growth model, the autoregressive cross-lagged model, the autoregressive latent trajectory model, and the latent change score model. The authors first overview each of these models through evaluating their different assumptions surrounding the nature of change and ho…
Pathways through opiate use and offending
Confounding in longitudinal studies in addiction treatment research
Background: The effectiveness of treatment for people with substance use disorders is usually examined using longitudinal cohorts. In these studies, treatment is often considered as a time-varying exposure. The aim of this commentary is to examine confounding in this context, when the confounding variable is time-invariant and when it is time-varying. Method: Types of confounding are described with examples and illustrated using path diagrams. Si…
Does income relate to health due to psychosocial or material factors? Consistent support for the psychosocial hypothesis requires operationalization with income rank not the Yitzhaki Index
Why does Income Relate to Depressive Symptoms? Testing the Income Rank Hypothesis Longitudinally
An Existential-Humanistic View of Personality Change
Increasingly, psychological research has indicated that an individual's personality changes across the lifespan. We aim to better understand personality change by examining if personality change is linked to striving towards fulfilment, as suggested by existential-humanistic theories of personality dynamics. Using the Wisconsin Longitudinal Study, a cohort of 4,733 mid-life individuals across 10 years, we show that personality change was signific…
Do hot spots of deprivation predict the rates of suicide within London boroughs
Geographical epidemiology, spatial analysis and geographical information systems
We provide a relatively non-technical glossary of terms and a description of the tools used in spatial or geographical epidemiology and associated geographical information systems. Statistical topics included cover adjustment and standardisation to allow for demographic and other background differences, data structures, data smoothing, spatial autocorrelation and spatial regression. We also discuss the rationale for geographical epidemiology and …
Sequence analysis in multilevel models. A study on different sources of patient cues in medical consultations
Negative life events, social support and gender difference in depression
Ecological association between suicide rates and indices of deprivation in the north west region of England
Background and objective: Most published research on the ecological relationship between suicide rates and indices of deprivation uses only one level of population aggregation—for example, by local authorities. These ecological associations have been studied at both the local authority and the electoral ward level. Methods: Data on all deaths for which suicide or an open verdict was returned between 1996 and 1998 in the North West Government Offi…
Prevalence of psychiatric disorders in young people in the care system
Recently, professional and political concern has grown about the severity and types of problems experienced by young people in the care system, this group being one of the most vulnerable in terms of psychological disturbance. Their risk of psychiatric ill health is higher than that of any other easily identified group in our society,1 and studies have consistently identified a high incidence of behavioural problems.2 No study has systematically …
The Camberwell Assessment of Need
BACKGROUND: People with severe mental illness often have a complex mixture of clinical and social needs. The Camberwell Assessment of Need (CAN) is a new instrument which has been designed to provide a comprehensive assessment of these needs. There are two versions of the instrument: the clinical version has been designed to be used by staff to plan patients' care; whereas the research version is primarily a mental health service evaluation tool.…
A Brief Mental Health Outcome Scale
BACKGROUND: The Global Assessment of Functioning (GAF) is a quick and simple measure of overall psychological disturbance. However, there is little research on the reliability and validity of this measure in severely mentally ill populations. METHOD: Multidisciplinary keyworkers assessed 103 patients at monthly intervals over a 6-month period. Overall GAF scores were obtained, with additional separate ratings for symptoms and disability. These we…
Cognitive behavioural therapy for drug‐resistant psychosis
A small controlled trial of cognitive behaviour therapy for drug‐resistant psychosis is reported. The study was designed as a pilot study for a future larger and longer randomized controlled trial. The therapy was offered to patients with a diagnosis of schizophrenia or schizo‐affective psychosis who presented unremitting positive symptoms. An average of 16 sessions were delivered over a six‐month period. The results of this pilot study are promi…
Measuring psychiatric disorder in the community
SYNOPSIS Many of the standardized interviews currently used in psychiatry require the interviewer to use expert psychiatric judgements in deciding upon the presence or absence of psychopathology. However, when case definitions are standardized it is customary for clinical judgements to be replaced with rules. The Clinical Interview Schedule was therefore revised, in order to increase standardization, and to make it suitable for use by ‘lay’ inter…
Design and Analysis of Reliability Studies
An introduction to measurement models measures of proximity, agreement and disagreement reliability, consistency and stability designs for reliability studies covariance-components models components of variance statistical methods for categorical measurements. Appendices: expected values linear combinations of measurements the delta technique computer software
Cyclical variation in psychotropic drug prescription
In this study it is shown that drug prescription is subject to cyclical variation throughout the year, but that the patterns of variation for different types of drug are different. Some of the reasons for, and the implications of, this finding are discussed
