Abstract
Objective: This review is to systematically summarize the studies examining physical activity questionnaires in children and adolescents and assess the overall validity and reliability, providing evidence on epidemiology research of physical activity in youth. Methods: A meta-analysis was performed using Stata 14.0 software. PubMed/Medline and EMBASE databases using the following terms:'Physical Activity'AND (' Questionnaire'OR'Self-report'OR'Recall') AND'Valid*'AND (' Reliab*'OR'Reproducib*'OR'Sensitiv*'OR'Responsiv*') AND (' Child*' OR'Adolescen*'OR'Youth') were searched from January 2008 to December 2018. Articles meeting the inclusion criteria were screened and adopting 'COnsensusbased Standards for the selection of health status Measurement Instruments' to evaluate the quality of the included studies. Results: This review yielded 17 articles on 20 different physical activity questionnaires, the total number of 2 778 participants for validity study and 2 137 participants for reliability study. The combined values of correlation coefficients in validity study were 0.27 (95%CI: 0.23-0.31) for moderate-to-vigorous intensity physical activity, 0.24 (95%CI: 0.18-0.30) for moderate intensity physical activity, 0.33 (95%CI: 0.24-0.42) for vigorous intensity physical activity. The combined values of intraclass correlation coefficients in reliability study were 0.75 (95%CI: 0.68-0.83) for moderate-to-vigorous intensity physical activity, 0.56 (95%CI: 0.46-0.65) for moderate intensity physical activity, 0.68 (95%CI: 0.61-0.75) for vigorous intensity physical activity. Conclusion: Until now, no questionnaires were identified for good validity and reliability to assess the physical activity level in young population.

Abstract
BACKGROUND Health-related quality of life (HRQoL) measurement in elderly people can provide appropriate information for an optimal management of physical/mental conditions. The main objective of the present study was to quantitatively assess the HRQoL among healthy elder Iranian individuals as measured by the Short-Form 36 (SF-36) questionnaire, both overall and at the level of each its single component/domain. METHODS This study was designed as a systematic review and meta-analysis, following the "Preferred Reporting Results of Systematic Reviews and Meta-Analyses" (PRISMA) guidelines. Embase, PubMed/MEDLINE, ISI/Web of Science (WOS), Scopus, and Iranian databases such as MagIran, SID and Irandoc were mined from inception up to 1st September 2017. Also the grey literature (via Google Scholar) was mined. Two reviewers independently screened titles/abstracts, assessed full-text articles, extracted data, and appraised their quality using the "Strengthening the Reporting of Observational Studies in Epidemiology" (STROBE) checklist. RESULTS Twenty five studies were included. Mean overall HRQoL was 54.92 [95%CI 51.50-58.33], lower than the value found by studies done in other countries, especially in those economically developed. The sensitivity analysis indicated stability and reliability of results. Pooled scores of each HRQoL domain/sub-scale of the SF-36 questionnaire ranged from 49.77 (physical role functioning) to 63.02 (social role functioning). CONCLUSIONS HRQoL among healthy elder Iranian individuals is generally low. Health policy-makers should put HRQoL among the elderly as a priority of their agenda, implementing ad hoc programs and providing social, economic and psychological support, as well as increasing the participation of old people in the community life and use their experiences.

Systematic reviews. 2017;(1):248
Abstract
BACKGROUND Treatment intensity scores can predict mortality and estimate resource use. They may therefore be of interest for essential neonatal care in low resource settings where neonatal mortality remains high. We sought to systematically review neonatal treatment intensity scores to (1) assess the level of evidence on predictive performance in predicting clinical outcomes and estimating resource utilisation and (2) assess the applicability of the identified models to decision making for neonatal care in low resource settings. METHODS We conducted a systematic search of PubMed, EMBASE (OVID), CINAHL, Global Health Library (Global index, WHO) and Google Scholar to identify studies published up until 21 December 2016. Included were all articles that used treatments as predictors in neonatal models. Individual studies were appraised using the CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS). In addition, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used as a guiding framework to assess certainty in the evidence for predicting outcomes across studies. RESULTS Three thousand two hundred forty-nine articles were screened, of which ten articles were included in the review. All of the studies were conducted in neonatal intensive care units with sample sizes ranging from 22 to 9978, with a median of 163. Two articles reported model development, while eight reported external application of existing models to new populations. Meta-analysis was not possible due heterogeneity in the conduct and reporting of the identified studies. Discrimination as assessed by area under receiver operating characteristic curve was reported for in-hospital mortality, median 0.84 (range 0.75-0.96, three studies), early adverse outcome and late adverse outcome (0.78 and 0.59, respectively, one study). CONCLUSION Existing neonatal treatment intensity models show promise in predicting mortality and morbidity. There is however low certainty in the evidence on their performance in essential neonatal care in low resource settings as all studies had methodological limitations and were conducted in intensive care. The approach may however be developed further for low resource settings like Kenya because treatment data may be easier to obtain compared to measures of physiological status.

Abstract
PURPOSE OF REVIEW The present review aims to provide an update on the various practical applications of the STOP-Bang questionnaire in anesthesia, surgery, and perioperative medicine. RECENT FINDINGS The STOP-Bang questionnaire was originally validated as a screening tool to identify surgical patients who are at high-risk of obstructive sleep apnea (OSA). A recent meta-analysis confirmed that STOP-Bang is validated for use in the sleep clinic, surgical, and general population. Patients with a STOP-Bang score of 0--2 can be classified as low-risk for moderate-to-severe OSA. Those with a score of 5--8 can be classified as high-risk for moderate-to-severe OSA. In patients with a score of 3 or 4, a specific combination of a STOP score at least 2 + BMI more than 35 kg/m or STOP score at least 2 + male or STOP score at least 2 + neck circumference more than 40 cm indicates higher risk for moderate-to-severe OSA. Further, patients with a STOP-Bang score at least 3 can be classified as high risk for moderate-to-severe OSA if the serum HCO3 at least 28 mmol/l. STOP-Bang can be used as a novel tool for perioperative risk stratification because it easily identifies patients who are at increased risk of perioperative complications. SUMMARY STOP-Bang at least 3 was recommended previously to identify the suspected or undiagnosed OSA. To reduce the false positive cases and to improve its specificity, a stepwise stratification is recommended to identify the patients at high risk of moderate-to-severe OSA. Because of its practical application, STOP-Bang is a useful screening tool for patients with suspected or undiagnosed OSA.

Abstract
This systematic review examines the characteristics and psychometric properties of the instruments used to assess self-care behaviors among persons with type 2 diabetes. Electronic databases were searched for relevant studies published in English within the past 20 years. Thirty different instruments were identified in 75 articles: 18 original instruments on type 2 diabetes mellitus self-care, 8 translated or revised version, and 4 not specific but relevant to diabetes. Twenty-one instruments were multidimensional and addressed multiple dimensions of self-care behavior. Nine were unidimensional: three focusing exclusively on medication taking, three on diet, one on physical activity, one on self-monitoring of blood glucose, and one on oral care. Most instruments (22 of 30) were developed during the last decade. Only 10 were repeated more than once. Nineteen of the 30 instruments reported both reliability and validity information but with varying degrees of rigor. In conclusion, most instruments used to measure self-care were relatively new and had been applied to only a limited number of studies with incomplete psychometric profiles. Rigorous psychometric testing, operational definition of self-care, and sufficient explanation of scoring need to be considered for further instrument development.

Women's health issues : official publication of the Jacobs Institute of Women's Health. 2015;(5):586-600
Abstract
PURPOSE Women's poor postpartum psychosocial and behavioral health may negatively affect them and their infants. Validated postpartum screening scales can help to identify problems early, but currently there is limited knowledge in this area. Thus, we conducted a systematic examination of self-administered psychosocial and behavioral scales validated for postpartum women in the United States in the domains of depression, body image, diet, physical activity, smoking, and alcohol use. We examined the characteristics of included scales, their validation samples, and reported psychometric properties. METHOD Nine databases were searched during October 2014 through February 2015. After meeting inclusion/exclusion criteria, article information was extracted independently by two authors, compared, and differences were resolved through discussions. RESULTS The final sample included 23 published articles covering 19 scales. Seventeen were in the domain of depression, and one each in physical activity and dietary domains. None was found in the domains of body image, smoking, or alcohol use. The number of scale items varied from 2 to 35. The majority of scales were originally designed for postpartum women, and validated in one or two postpartum studies with samples of predominantly adult women. If reported, scale reliability coefficients were generally 0.80 or greater and validity coefficients of 0.70 or greater. Five depression scales had favorable sensitivity and specificity using standard cutpoints, but only one was tested across adolescent, low-income, and predominantly ethnic minority postpartum populations. CONCLUSION No U.S.-validated postpartum scales were found for body image, smoking, or alcohol use. Most scales had limited validity testing, and validation was in predominantly advantaged samples. Further scale development and testing are recommended.

African health sciences. 2015;(3):931-40
Abstract
BACKGROUND Well developed and validated lifestyle cardiovascular disease (CVD) risk factors questionnaires is the key to obtaining accurate information to enable planning of CVD prevention program which is a necessity in developing countries. We conducted this review to assess methods and processes used for development and content validation of lifestyle CVD risk factors questionnaires and possibly develop an evidence based guideline for development and content validation of lifestyle CVD risk factors questionnaires. MATERIALS/METHODS Relevant databases at the Stellenbosch University library were searched for studies conducted between 2008 and 2012, in English language and among humans. Using the following databases; pubmed, cinahl, psyc info and proquest. Search terms used were CVD risk factors, questionnaires, smoking, alcohol, physical activity and diet. RESULTS Methods identified for development of lifestyle CVD risk factors were; review of literature either systematic or traditional, involvement of expert and /or target population using focus group discussion/interview, clinical experience of authors and deductive reasoning of authors. For validation, methods used were; the involvement of expert panel, the use of target population and factor analysis. CONCLUSION Combination of methods produces questionnaires with good content validity and other psychometric properties which we consider good.

[Patients on the move: validated methods to quantify physical activity].
Bakker, EA, Eijsvogels, TM, de Vegt, F, Busser, GS, Hopman, MT, Verbeek, A
Nederlands tijdschrift voor geneeskunde. 2015;:A8709
Abstract
Physical activity is an important component in the maintenance and improvement of general health; physical inactivity is, however, an increasing problem in the Netherlands. Requests for advice on physical activity are increasing within the healthcare. Assessment of an individual's physical activity pattern is required to provide tailored advice. There are a number of methods for measuring physical activity; these are divided into subjective and objective methods. Subjective measures include physical activity questionnaires and diaries. Objective measures include indirect calorimetry, measurement with doubly labelled water, heart-rate monitoring and the use of an accelerometer or pedometer. The choice of method depends predominantly on the aim of the measurement, and the availability of personnel, time and financial resources. In clinical practice a validated questionnaire is usually the preferred method, but when measuring effects this should be combined with an objective measurement instrument.

Helmerhorst, HJ, Brage, S, Warren, J, Besson, H, Ekelund, U
The international journal of behavioral nutrition and physical activity. 2012;:103
Abstract
Physical inactivity is one of the four leading risk factors for global mortality. Accurate measurement of physical activity (PA) and in particular by physical activity questionnaires (PAQs) remains a challenge. The aim of this paper is to provide an updated systematic review of the reliability and validity characteristics of existing and more recently developed PAQs and to quantitatively compare the performance between existing and newly developed PAQs.A literature search of electronic databases was performed for studies assessing reliability and validity data of PAQs using an objective criterion measurement of PA between January 1997 and December 2011. Articles meeting the inclusion criteria were screened and data were extracted to provide a systematic overview of measurement properties. Due to differences in reported outcomes and criterion methods a quantitative meta-analysis was not possible.In total, 31 studies testing 34 newly developed PAQs, and 65 studies examining 96 existing PAQs were included. Very few PAQs showed good results on both reliability and validity. Median reliability correlation coefficients were 0.62-0.71 for existing, and 0.74-0.76 for new PAQs. Median validity coefficients ranged from 0.30-0.39 for existing, and from 0.25-0.41 for new PAQs.Although the majority of PAQs appear to have acceptable reliability, the validity is moderate at best. Newly developed PAQs do not appear to perform substantially better than existing PAQs in terms of reliability and validity. Future PAQ studies should include measures of absolute validity and the error structure of the instrument.

Patient questionnaires in rheumatoid arthritis: advantages and limitations as a quantitative, standardized scientific medical history.
Pincus, T, Yazici, Y, Bergman, MJ
Rheumatic diseases clinics of North America. 2009;(4):735-43, vii
Abstract
In many chronic diseases, objective gold standard measures such as blood pressure, cholesterol, and bone densitometry often provide most of the information used to establish a diagnosis and guide therapy. By contrast, in inflammatory rheumatic diseases, information from a patient history usually is considerably more prominent in clinical management. Patient history data can be recorded as standardized, quantitative scientific data through use of validated self-reported questionnaires. Patient questionnaires address the primary concerns of patients and their families. Questionnaire scores distinguish active from control treatments in clinical trials at similar levels to swollen and tender joint counts or laboratory tests. Patient questionnaire data are correlated significantly with joint counts, radiographic scores, and laboratory tests, but usually are far more significant than these measures in the prognosis of severe outcomes of rheumatoid arthritis (RA), including work disability, costs, and premature death. Limitations of patient questionnaires are based on cultural features involving variation in responses among ethnic groups, and a need for translation, although translated questionnaires can be as valuable as a translator. Patient questionnaires do not replace further medical history, physical examination, laboratory tests, and imaging data, and they require interpretation in a context of these standard sources of information at any clinical encounter. Patient questionnaires are useful to monitor patient status in usual clinical care, with almost no effort on the part of the physician and staff if distributed by the receptionist in the infrastructure of office practice.
