The meaning of membership as perceived by Plymouth Brethren

Thesis (Ph.D.)--Boston UniversityThe purpose of the investigation was to determine how communicants of the religious body, Plymouth Brethren II, the Open Brethren, have perceived the meaning of membership. An assembly in Massachusetts and three assemblies in Missouri were chosen as examples. From these assemblies fifty-one individuals were chosen for personal interviews. They were selected in such a manner that the numbers of people in the cross-section reflected the observed proportion of age and sex differences in the assemblies studied. The Brethren are a religious body who originated in Dublin about 1827. They are called Plymouth Brethren by those outside the fellowship. Assemblies of the body were gathered in England at an early date, and the movement can be found in most of the English-speaking countries of the world. The assemblies are characterized by a dispensationalist theology, a strict social code of conduct, and an organization, or lack of it, patterned on their interpretation of the New Testament church. There are no clergy, no boards. Each missionary goes out on his own by faith. The movement has been riven by schism over the years. The Open Brethren is the largest of the Brethren groups [TRUNCATED

Assessing The Validity Of A Culturally Modified Drinking Motives Questionnaire For Use In Aboriginal Communities

Alcohol related harms disproportionately affect Aboriginal people in Australia. Motives to drink have been identified as the most proximal factor to alcohol consumption.The aim of this study is to assess the validity of a culturally modified Drinking Motives Questionnaire-Revised (DMQ-R) (Cooper, 1994) with Aboriginal participants. The study was cross sectional, utilising data collected via face-to-face surveys with a sample of adult Aboriginal participants. A convenience sample of 135 Aboriginal men (n=41) and women (n=94) from the Pilbara Region of Western Australia, who had consumed alcohol in the preceding 12 months. The Culturally modified DMQ-R (CDMQ-R) developed in consultation with Aboriginal community researchers and a local Aboriginal Community Reference Group was the primary outcome measure for this study. Confirmatory Factor Analysis indicated the four-factor model of drinking motives as measured by a culturally modified DMQ-R was valid for use with Aboriginal people of the Pilbara region. While most items loaded on the factor solution as hypothesised, there were some minor discrepancies which suggest further modification may be needed. In addition, the reduction of the original five-point scale to a three-point scale created statistical challenges. Future research might seek to further refine the DMQ-R for this population and determine an appropriate method for expanding the response scale incorporating advice from Aboriginal people

Women’s Barriers to Weight Loss, Perception of Future Diabetes Risk and Opinions of Diet Strategies Following Gestational Diabetes: An Online Survey

Weight loss after gestational diabetes (GDM) reduces the risk of type 2 diabetes (T2DM); however, weight loss remains challenging in this population. In order to explore perceptions of T2DM risk, barriers to weight loss, and views of diet strategies in women with previous GDM, a cross-sectional online survey of n = 429 women in Australia aged ≥18 years with previous GDM was conducted. Opinions of intermittent energy restriction (IER) were of interest. Seventy-five percent of responders (n = 322) had overweight or obesity, and 34% (n = 144) believed they had a high risk of developing T2DM. Within the Theoretical Domains Framework, barriers to weight loss were prominently related to Environmental Context and Resources, Beliefs about Capabilities, and Behavioural Regulation. Exercising was the most tried method of weight loss over other diet strategies (71%, n = 234) and weight loss support by a dietician was appealing as individual appointments (65%, n = 242) or an online program (54%, n = 200). Most women (73%, n = 284) had heard of IER (the “5:2 diet”), but only 12% (n = 34) had tried it. Open comments (n = 100) revealed mixed views of IER. Women in Australia with previous GDM were found to lack a self-perceived high risk of developing T2DM and expressed barriers to weight loss related to their family environment, beliefs about their capabilities and behavioural regulation. IER is appealing for some women with previous GDM; however, views vary

Incorporating polygenic risk into the Leicester Risk Assessment score for 10-year risk prediction of type 2 diabetes

Aims: We evaluated whether incorporating information on ethnic background and polygenic risk enhanced the Leicester Risk Assessment (LRA) score for predicting 10-year risk of type 2 diabetes. Methods: The sample included 202,529 UK Biobank participants aged 40–69 years. We computed the LRA score, and developed two new risk scores using training data (80% sample): LRArev, which incorporated additional information on ethnic background, and LRAprs, which incorporated polygenic risk for type 2 diabetes. We assessed discriminative and reclassification performance in a test set (20% sample). Type 2 diabetes was ascertained using primary care, hospital inpatient and death registry records. Results: Over 10 years, 7,476 participants developed type 2 diabetes. The Harrell's C indexes were 0.796 (95% Confidence Interval [CI] 0.785, 0.806), 0.802 (95% CI 0.792, 0.813), and 0.829 (95% CI 0.820, 0.839) for the LRA, LRArev and LRAprs scores, respectively. The LRAprs score significantly improved the overall reclassification compared to the LRA (net reclassification index [NRI] = 0.033, 95% CI 0.015, 0.049) and LRArev (NRI = 0.040, 95% CI 0.024, 0.055) scores. Conclusions: Polygenic risk moderately improved the performance of the existing LRA score for 10-year risk prediction of type 2 diabetes

Development and Validation of an Online Survey to Assess Perception of Diabetes Risk and Barriers and Facilitators to Weight Loss Following Gestational Diabetes

Our objective was to describe the development and validation of a survey investigating barriers to weight loss, perception of diabetes risk, and views of diet strategies following gestational diabetes (GDM). The survey underwent three stages of development: generation of items, expert evaluation, and pilot testing. A content validation index (CVI) was calculated from expert responses regarding item relevance, coherence, clarity, and response options. Experts also responded to the domain fit of questions linked to the Theoretical Domains Framework (TDF). Pilot responders answered the survey and responded to review questions. Six experts in the field of nutrition, midwifery, psychology, or other health or medical research completed the expert review stage of the survey. In the pilot test, there were 20 responders who were women with previous GDM and who were living in Australia. The overall CVI from the expert review was 0.91. All questions except one received an I-CVI of >0.78 for relevance (n = 35). Fourteen of the 27 items linked to the TDF received an agreement ratio of <1.0. Twenty-seven of the 31 pilot questions were completed by ≥90% of responders. Pilot review questions revealed an agreement percentage of ≥86% (n = 12) regarding the survey’s ease to complete, understand, importance, length, and interest level. The final survey tool consists of 30 items and achieved content validation through expert evaluation and pilot testing

Sexual function in 16- to 21-year-olds in Britain

Purpose: Concern about young people's sexuality is focused on the need to prevent harmful outcomes such as sexually transmitted infections and unplanned pregnancy. Although the benefit of a broader perspective is recognized, data on other aspects of sexuality, particularly sexual function, are scant. We sought to address this gap by measuring the population prevalence of sexual function problems, help seeking, and avoidance of sex in young people. Methods: A cross-sectional stratified probability sample survey (Natsal-3) of 15,162 women and men in Britain (response rate: 57.7%), using computer-assisted self-interviews. Data come from 1875 (71.9%) sexually active, and 517 sexually inactive (18.7%), participants aged 16–21 years. Measures were single items from a validated measure of sexual function (the Natsal-SF). Results: Among sexually active 16- to 21-year-old participants, 9.1% of men and 13.4% of women reported a distressing sexual problem lasting 3 months or more in the last year. Most common among men was reaching a climax too quickly (4.5%), and among women was difficulty in reaching climax (6.3%). Just over a third (35.5%) of men and 42.3% of women reporting a problem had sought help, but rarely from professional sources. Among those who had not had sex in the last year, just &gt;10% of young men and women said they had avoided sex because of sexual difficulties. Conclusions: Distressing sexual function problems are reported by a sizeable minority of sexually active young people. Education is required, and counseling should be available, to prevent lack of knowledge, anxiety, and shame progressing into lifelong sexual difficulties

Reducing car-use for leisure: can organised walking groups switch from car travel to bus and train walks?

This paper deals with the significant leisure travel sector, focusing on the attitudes of organised walking groups towards public transport use. A series of interviews with walking group leaders explored the design of organised walks, and factors affecting journeys to and from start points. The themes presented suggest an overlying group culture involving mainly circular walks, reached by car. The research indicates an underlying engrained dependency on cars to reach walks and a degree of opposition to using public transport, which generally contradicts widely–held attitudes towards protecting the environment. Future research should focus more in depth on the long-term removal of psychological barriers to using public transport for leisure, and persuasive measures aimed at groups
