Measuring extraordinary experiences and beliefs: A validation and reliability study.

ABSTRACT: Background: Belief in the paranormal is widespread worldwide. Recent surveys suggest that subjective experiences of the paranormal are common. A concise instrument that adequately evaluates beliefs as distinct from experiences does not currently exist. To address this gap, we created the Noetic Experiences and Beliefs Scale (NEBS) which evaluates belief and experience as separate constructs. Methods: The NEBS is a 20-item survey with 10 belief and 10 experience items rated on a visual analog scale from 0-100. In an observational study, the survey was administered to 361 general population adults in the United States and a subsample of 96 one month later. Validity, reliability and internal consistency were evaluated. A confirmatory factor analysis was conducted to confirm the latent variables of belief and experience. The survey was then administered to a sample of 646 IONS Discovery Lab participants to evaluate divergent validity and confirm belief and experience as latent variables of the model in a different population. Results: The NEBS demonstrated convergent validity, reliability and internal consistency (Cronbach's alpha Belief 0.90; Experience 0.93) and test-retest reliability (Belief: r = 0.83 ; Experience: r = 0.77). A confirmatory factor analysis model with belief and experience as latent variables demonstrated a good fit. The factor model was confirmed as having a good fit and divergent validity was established in the sample of 646 IONS Discovery Lab participants. Conclusions: The NEBS is a short, valid, and reliable instrument for evaluating paranormal belief and experience.

Project description:BackgroundCardiovascular disease (CVD) and stroke are global public health problems and cause high mortality, especially in low- and middle-income countries. Knowledge and awareness are critical points in managing the risk in the general population. The Attitudes and Beliefs about Cardiovascular Disease (ABCD) risk questionnaire was developed to evaluate the awareness of stroke and CVD risk. Thus, the government can set up a practical risk assessment and management programme. The initiative will encourage people to seek healthcare timely and reduce the possibilities of developing complications.ObjectiveThis study aimed to translate and validate the ABCD risk questionnaire into the Malay language and evaluate the psychometric properties of the Malay version in the general population in Malaysia.MethodsThe questionnaire was translated using a standard forward-backwards translation method. The validation was perfomed by both expert panels and a potential user group. Next, the exploratory factor analysis was conducted to examine factorial validity. The respondents were selected from the government health clinics and according to the study criteria irrespective of the CVD risk. We used Cronbach's alpha and Raykov's rho to explore the internal consistency and composite reliability of the 18 items from three domains. Finally, the confirmatory factor analysis (CFA) was conducted using a robust maximum likelihood estimator.ResultsThe content and face validity indices were determined to be 0.94 and 0.99 respectively. Data were obtained from 179 respondents (mean age, 36.8 years; female, 68.2%; secondary level education, 51.1%). The internal consistency and composite reliability of the domains showed good results ranging from 0.643 to 0.885. The factor loadings of each item were acceptable (> 0.3), and the fit indices from the CFA resulted in a good model fit [χ2 (p-value = 0.16), SRMR = 0.054, RMSEA = 0.029, CFI = 0.99, TLI = 0.99)].ConclusionsThe Malay version of the ABCD risk questionnaire is a valid and reliable tool to assess the awareness of stroke and CVD risk in the general population in Malaysia.

Project description:BackgroundAlmost 80% of global tobacco usage is concentrated in low- and-middle-income countries (LMICs) like India. Added to this, there is dearth of dedicated tobacco cessation specialist services in healthcare settings in these regions. Identification of challenges in the delivery of cessation interventions and understanding the experiences of tobacco users will aid in formulating successful quit strategies.ObjectivesThis qualitative study in India aimed to understand the perspectives of tobacco-using patients in healthcare facilities regarding tobacco use and cessation.MethodsThis qualitative study was conducted in urban and rural areas of four study sites, two each in the North and South India. Using purposive sampling, patients who were tobacco users were selected from healthcare facilities. The interviews were transcribed, coded and organised into themes. Analysis was done using NVivo 10 software.ResultsA total of 22 in-depth interviews were conducted on participants aged 23 to 80 years who were either current or past tobacco users. A majority of the participants were aware of their increased health risks associated with tobacco consumption and had attempted quitting; however, barriers such as peer influence, formed habit, certain cultural barriers and the addictive nature of nicotine prevented them from successfully quitting. Familial and peer support, the government's role in spreading public awareness, and limiting the sale of tobacco were stated as facilitators for tobacco cessation.ConclusionsThe findings of this study point out that despite awareness of the perils of tobacco among smokers, there are various barriers and beliefs related to tobacco use and cessation. These findings would prove advantageous for policy-makers to implement and promote addiction treatment programmes for successful tobacco cessation efforts. In order to optimise strategies, policies must be well informed by ongoing dialogue between the public, service providers and policy-makers.

Project description:BackgroundThere is strong evidence suggesting that higher levels of cardiorespiratory fitness (CRF) are associated with a healthier metabolic profile, and that CRF can serve as a powerful predictor of morbidity and mortality. In this context, a smartphone app based on the 2-km walk test (UKK test) would provide the possibility to assess CRF remotely in individuals geographically distributed around a country or continent, and even between continents, with minimal equipment and low costs.ObjectiveThe overall aim of this study was to evaluate the validity and reliability of 2kmFIT-App developed for Android and iOS mobile operating systems to estimate maximum oxygen consumption (VO2max) as an indicator of CRF. The specific aims of the study were to determine the validity of 2kmFIT-App to track distance and calculate heart rate (HR).MethodsTwenty participants were included for field-testing validation and reliability analysis. The participants completed the UKK test twice using 2kmFIT-App. Distance and HR were measured with the app as well as with accurate methods, and VO2max was estimated using the UKK test equation.ResultsThe validity results showed the following mean differences (app minus criterion): distance (-70.40, SD 51.47 meters), time (-0.59, SD 0.45 minutes), HR (-16.75, SD 9.96 beats/minute), and VO2max (3.59, SD 2.01 ml/kg/min). There was moderate validity found for HR (intraclass correlation coefficient [ICC] 0.731, 95% CI -0.211 to 0.942) and good validity found for VO2max (ICC 0.878, 95% CI -0.125 to 0.972). The reliability results showed the following mean differences (retest minus test): app distance (25.99, SD 43.21 meters), app time (-0.15, SD 0.94 seconds), pace (-0.18, SD 0.33 min/km), app HR (-4.5, 13.44 beats/minute), and app VO2max (0.92, SD 3.04 ml/kg/min). There was good reliability for app HR (ICC 0.897, 95% CI 0.742-0.959) and excellent validity for app VO2max (ICC 0.932, 95% CI 0.830-0.973). All of these findings were observed when using the app with an Android operating system, whereas validity was poor when the app was used with iOS.ConclusionsThis study shows that 2kmFIT-App is a new, scientifically valid and reliable tool able to objectively and remotely estimate CRF, HR, and distance with an Android but not iOS mobile operating system. However, certain limitations such as the time required by 2kmFIT-App to calculate HR or the temperature environment should be considered when using the app.
