The social media scale for depression in adolescence
Social media forms a significant part of adolescents' lives, yet its impact on depression is unclear. We aimed to develop a questionnaire assessing different ways of using social media, and use it to understand potential associations with depression in adolescence. One thousand one hundred and forty adolescents completed an item pool. Factor analyses were conducted to derive the Social Media Scale (SMS). Ant Colony Optimization was used to develo…
Supporting Patients with Psychosis in the Community To Stand Up and Move More: Perspectives of Community Mental Health Staff
People with psychosis typically show high levels of sedentary behaviour and low levels of physical activity. Effective interventions are needed, and staff will play a crucial role in implementation. Aims: To understand staff perspectives on reducing sedentary behaviour and increasing physical activity. Eighteen staff from NHS mental health trust community teams were interviewed, with data analysed using reflexive thematic analysis. Four themes we…
Supporting movement and physical activity in people with psychosis: A qualitative exploration of the carer perspective
BACKGROUND: The need to increase exercise and decrease sedentary behaviour in people diagnosed with psychosis is well-recognised. AIMS: We set out to explore caregivers' perspectives on what supports and prevents physical activity, and how to use carers' support most effectively. METHOD: Fourteen caregivers of people diagnosed with psychosis were interviewed. Data were analysed using reflexive thematic analysis, in collaboration with caregivers. …

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 …
The Disease Influenced Vaccine Acceptance Scale-Six (Divas-6): Validation of a Measure to Assess Disease-Related Covid-19 Vaccine Attitudes and Concerns
Patients with underlying comorbidities are particularly vulnerable to poor outcomes from SARS-CoV-2 infection. Despite the context-specific nature of vaccine hesitancy, there are currently no scales that incorporate disease or treatment-related hesitancy factors. We developed a six-item scale assessing disease-related COVID-19 vaccine attitudes and concerns (The Disease Influenced COVID-19 Vaccine Acceptance Scale-Six: DIVAS-6). A survey incorpor…
Annual Research Review: Immersive virtual reality and digital applied gaming interventions for the treatment of mental health problems in children and young people: the need for rigorous treatment dev…
BACKGROUND: Mental health problems in children and young people are common and can lead to poor long-term outcomes. Despite the availability of effective psychological interventions for mental health disorders, only a minority of affected children and young people access treatment. Digital interventions, such as applied games and virtual reality (VR), that target mental health problems in children and young people may hold a key to increasing acc…
Paranoia and Grandiosity in the General Population: Differential Associations With Putative Causal Factors
Worry, negative self-beliefs, and sleep disturbance have been identified as contributory factors to the onset, maintenance, and severity of paranoia. We tested the specificity of these contributory factors to paranoia compared to grandiosity, a different type of delusional ideation. Data were used from 814 adults from the Nathan Kline Institute-Rockland (NKI-Rockland) study, a general population dataset. Paranoid and grandiose delusional ideation…
Online Social Endorsement and Covid-19 Vaccine Hesitancy in the United Kingdom
We explore the implications of online social endorsement for the Covid-19 vaccination program in the United Kingdom. Vaccine hesitancy is a long-standing problem, but it has assumed great urgency due to the pandemic. By early 2021, the United Kingdom had the world's highest Covid-19 mortality per million of population. Our survey of a nationally representative sample of UK adults ( N = 5,114) measured socio-demographics, social and political atti…
Sleep disturbance and psychiatric disorders
The Experience of Sleep Problems and Their Treatment in Young People at Ultra-High Risk of Psychosis: A Thematic Analysis
We view sleep disruption as a contributory causal factor in the development of psychotic experiences. Clinical trials indicate that psychological interventions targeting insomnia result in improvements in both sleep and psychotic experiences. The aim of this study was to gain the perspective of young people at ultra-high risk of psychosis on their sleep problems and associated psychological treatment. Interviews were conducted with 11 patients, a…
The concomitants of conspiracy concerns
PURPOSE: A conspiracy world view may be a form of mistrust that is typically corrosive to individual and societal well-being. Our aim was to establish the correlates of conspiracy thinking in an epidemiologically representative sample. METHODS: US National Comorbidity Survey-Replication (NCS-R) data were analysed from 5645 people who had completed the item "I am convinced there is a conspiracy behind many things in the world." Results were weight…
Virtual reality in the assessment, understanding, and treatment of mental health disorders
Mental health problems are inseparable from the environment. With virtual reality (VR), computer-generated interactive environments, individuals can repeatedly experience their problematic situations and be taught, via evidence-based psychological treatments, how to overcome difficulties. VR is moving out of specialist laboratories. Our central aim was to describe the potential of VR in mental health, including a consideration of the first 20 yea…
The effects of improving sleep on mental health (Oasis): A randomised controlled trial with mediation analysis
BACKGROUND: Sleep difficulties might be a contributory causal factor in the occurrence of mental health problems. If this is true, improving sleep should benefit psychological health. We aimed to determine whether treating insomnia leads to a reduction in paranoia and hallucinations. METHODS: We did this single-blind, randomised controlled trial (OASIS) at 26 UK universities. University students with insomnia were randomly assigned (1:1) with sim…
A Population-Based Study of Job Stress in Mexican Americans, non-Hispanic Blacks, and non-Hispanic Whites
There is little known about the association between socioeconomic status and job stress in Mexican Americans. To address this issue, data were originated on a community level using personal interviews from working Mexican Americans using a multistage probability sample. In this study we described the population’s sociodemographic characteristics, health conditions, and job stress measures in Mexican Americans, non-Hispanic Whites, and non-Hispani…

Environmental hazards and stress: Evidence from the Texas City Stress and Health Study
BACKGROUND: Substantial research has suggested that exposure to environmental health hazards, such as polluting industrial activity, has deleterious effects on psychological and physiological well-being. However, one gap in the existing literature is comparative analysis of objective and subjective exposure's relative association with various measurable outcomes of exposure. METHODS: These relationships were explored within a community sample of …
Perceived health change in the aftermath of a petrochemical accident: An examination of pre-accident, within-accident, and post-accident variables
BACKGROUND: Little research has been conducted on changes in perceived health after an industrial accident. Using data from an ongoing survey on stress and health in a petrochemical complex in Texas City, Texas, the associations of a petrochemical accident with perceived health changes were examined. METHODS: The mean changes in perceived mental and physical health across pre-accident, within-accident, and post-accident categories were compared. …

Public Support for Both the Environment and an Anti-Environmental President: Possible Explanations for the George W. Bush Anomaly
The authors explore the apparent anomaly of strong public support for the environment and popular public support for a president with a poor environmental rating by groups such as the League of Conservation Voters. In attempting to understand why there have not been public outcries against George W. Bush s anti-environmental policies like those that occurred during the Reagan presidency, the authors present three possible explanations: a lag time…
A cognitive model of the positive symptoms of psychosis
In the last 10 years a consensus has developed that the symptoms of psychosis may be better understood by linking the steps between the phenomenological experiences and social, psychological and neurobiological levels of explanation. Cognitive models of psychosis are an important link in this chain. They provide a psychological description of the phenomena from which hypotheses concerning causal processes can be derived and tested; social, indivi…
The Impact of Managed Care on the Use of Outpatient Mental Health and Substance Abuse Services in Puerto Rico
This paper estimates the impact of managed care on use of mental health services by residents of low-income areas in Puerto Rico. A quasi-experimental design evaluates the impact of a low capitation rate on a minority population using three waves of data from a random community sample. Results indicate that two years after introducing managed care, privatization of mental health services had minimal impact on use. Advocates had hoped health care …

Changes in Age and Sex Specific Tonsillectomy Rates: United States, 1970-1977
National estimates of tonsillectomy rates were generated from the Hospital Discharge Survey for the years 1970 and 1977. A comparison of the rates over the seven-year period revealed significant declines in T&A for all age and sex categories and in tonsillectomy alone for males aged 20 through 29. It was also observed that sex differences found in 1970 persisted in 1977. (Am J Public Health 1982; 72:488-491.)

Geographic variations in breast cancer mortality: Do higher rates imply elevated incidence or poorer survival
OBJECTIVES: Mortality rates from breast cancer are approximately 25% higher for women in the northeastern United States than for women in the South or West. This study examined the hypothesis that the elevation is due to decreased survival rather than increased incidence. METHODS: Data on breast cancer incidence, treatment, and mortality were reviewed. RESULTS: The elevated mortality in the Northeast is apparent only in older women. For women age…
Hospitalization for medical-legal and other abortions in the United States 1970-1977
The National Hospital Discharge Survey records for medical-legal, spontaneous, and "other" abortions (ICDA-8 640-641, 643, and 644 respectively) for 1970-1977 were analyzed to investigate the impact of liberalized access to abortion on abortion-related morbidity in the United States. The analysis suggests that in census regions where an increase in medical-legal abortions performed in hospitals occurred over the study period there was an associat…

Depressive Symptoms in Relation to Physical Health and Functioning in the Elderly
The associations between depressive symptoms and functional disability and chronic conditions are examined in an elderly cohort of 2,806 noninstitutionalized men and women living in New Haven, Connecticut who were interviewed in 1982 as a part of the Yale Health and Aging Project. The aim is to explore several potential sources of invalidity in using the Center for Epidemiologic Studies-Depression scale (CES-D) to measure depressive symptoms in e…
Estimation of Interregional Trade Flows: A Markov Chain Approach
Methods for estimating interregional trade flows do not deal explicitly with middlemen. As a result, in many cases, the estimated flows are biased. In this paper a model which allows an explicit treatment of the middlemen problem is offered. It is suggested that under some simple assumptions regarding the behaviour of middlemen, a Markov chain approach is appropriate. The model is applied to the Israeli dairy industry in 1973. The results obtaine…
Factors Affecting the Utilization of Specialty and General Medical Mental Health Services
This study compares the extent to which need, predisposing, and enabling factors affect the use of mental health services in the specialty and general medical health sectors during a 6-month period. Data are drawn from the first wave of interviews of the Epidemiological Catchment Area (ECA) project at the Yale University site. The results indicate that 1) in the general population, factors affecting use of the two sectors differ; 2) among those u…
