Factorial invariance of the Patient Health Questionnaire and Generalized Anxiety Disorder Questionnaire.

Objectives: The UK's Improving Access to Psychological Therapies (IAPT) programme uses the Patient Health Questionnaire Depression Scale (PHQ-9; Kroenke, Spitzer, & Williams, , J. Gen. Intern.

Effect of dyspepsia on survival: a longitudinal 10-year follow-up study.

Objectives: Most chronic and recurrent gastrointestinal (GI) symptoms in the community are caused by functional GI disorders, such as functional dyspepsia and irritable bowel syndrome (IBS). It is not known, however, whether these conditions affect mortality. We present the results of a large community-based prospective study that examines this issue.

The development, regulation and use of biopesticides for integrated pest management.

Over the past 50 years, crop protection has relied heavily on synthetic chemical pesticides, but their availability is now declining as a result of new legislation and the evolution of resistance in pest populations. Therefore, alternative pest management tactics are needed. Biopesticides are pest management agents based on living micro-organisms or natural products.

Integrated pest management portfolios in UK arable farming: results of a farmer survey.

Background: Farmers are faced with a wide range of pest management (PM) options that can be adopted in isolation or alongside complementary or substitute strategies. This paper presents the results of a survey of UK cereal producers, focusing on the character and diversity of PM strategies currently used by, or available to, farmers. In addition, the survey asked various questions pertaining to agricultural policy participation, attitude towards environmental issues, sources of PM advice and information and the important characteristics of PM technologies.

Irritable bowel syndrome: a 10-yr natural history of symptoms and factors that influence consultation behavior.

Objective: Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder. The natural history of the condition has been studied extensively, but few studies have examined factors that predict its new onset or health care-seeking behavior.

Methods: Individuals, now aged 50-59 yr, originally enrolled in a population-screening program for Helicobacter pylori (H.

Effect of sibling number in the household and birth order on prevalence of Helicobacter pylori: a cross-sectional study.

Background: Infection with Helicobacter pylori (H. pylori) is acquired mainly in childhood, with studies demonstrating this is related to living conditions. Effects of sibling number and birth order on prevalence of infection have not been extensively studied.

Who consults with dyspepsia? Results from a longitudinal 10-yr follow-up study.

Objective: Dyspepsia is common, and the condition is often chronic, with a relapsing and remitting nature. Factors influencing the decision to consult a physician with symptoms remain unclear.

Methods: The authors conducted a 10-yr follow-up longitudinal survey of individuals originally involved in a community-screening program for Helicobacter pylori (H.

Initial poor quality of life and new onset of dyspepsia: results from a longitudinal 10-year follow-up study.

Background: Numerous studies examining the prevalence and natural history of dyspepsia in the general population have been conducted. However, few have reported the effect of quality of life on the development of dyspepsia. A 10-year longitudinal follow-up study examining the effect of quality of life on subsequent dyspepsia was performed.

A community screening program for Helicobacter pylori saves money: 10-year follow-up of a randomized controlled trial.

Background & Aims: Population screening and treatment of Helicobacter pylori has been advocated as a means of reducing mortality from gastric cancer, as well as dyspepsia and dyspepsia-related resource use. Previous programs have failed to demonstrate a significant effect on mortality or resource use, but follow-up was only for 1 or 2 years. We aimed to determine the effect of screening for H pylori on dyspepsia and dyspepsia-related resource use over 10 years.
