Design and validation of appearance and content of an oral health questionnaire for parents or caregivers of children with cerebral palsy
2018
Introduction: Cerebral palsy is a syndrome that involves a large number of childhood movement and posture disorders, resulting in activity limitation. It is attributed to non-progressive alterations in the fetal or infant brain. This disorder can also be accompanied by oral alterations, some of which can be prevented if the caretaker knows how to manage them. An adequate knowledge of oral health on the part of the caregivers has a positive impact on the oral status of their patients. Objective: To design and validate a questionnaire to assess the oral health knowledge of caregivers of children with cerebral palsy. Methods: A literature search was conducted to identify published questionnair…
Test-retest reliability of adolescents' self-reported physical activity item in two consecutive surveys.
2019
Background National monitoring of school-aged physical activity (PA) behaviours is necessary to inform policy makers. The Finnish School-aged Physical Activity (FSPA – LIITU in Finnish) is a physical activity monitoring study, collecting data from young adolescents aged 11 to 15 years through a nationally representative sample. This study included a single self-reported item question on moderate to vigorous intensity physical activity (MVPA) from the preceding seven days. The question is used widely in the WHO Collaborative Cross-National Health Behaviour in School-aged Children (HBSC) study as a measure of meeting international PA recommendations. This study evaluated the test-retest relia…
Reliability and validity of a new accelerometer-based device for detecting physical activities and energy expenditure.
2018
Background Objective assessments of sedentary behavior and physical activity (PA) by using accelerometer-based wearable devices are ever expanding, given their importance in the global context of health maintenance. This study aimed to determine the reliability and validity of a new accelerometer-based analyzer (Fibion) for detecting different PAs and estimating energy expenditure (EE) during a simulated free-living day. Methods The study consisted of two parts: a reliability (n = 18) and a validity (n = 19) test. Reliability was assessed by a 45 min protocol of repeated sitting, standing, and walking (i.e., 3 × 15 min, repeated twice), using both Fibion and ActiGraph. Validity was assesse…
The vaccinaTion & Hpv Knowledge (THinK) questionnaire: a reliability and validity study on a sample of women living in Sicily (southern-Italy)
2019
Objective The aim of this study was to introduce the VaccinaTion & Hpv Knowledge (THinK) questionnaire to assess knowledge about human papillomavirus (HPV) and attitude to HPV-vaccination. Its reliability and validity was demonstrated in a sample of women living in Sicily (southern Italy). Methods A cross-sectional survey was conducted on a sample of 220 women at the “Paolo Giaccone” University Hospital in Palermo (Sicily), aged 18–61. Data were analyzed through Cronbach’s alpha and exploratory factor analysis, followed by a structural equation model with measurement component. The two-level data structure was explicitly considered. Results Three dimensions were found: “knowledge of HP…
Glucose metabolism and self-regulation — Is insulin resistance a valid proxy of self-control?
2016
Abstract Glucose metabolism has been suggested as an underlying biological factor of self-control stimulating a range of studies exploring the associations between glucose and self-control. Research on interindividual trait-like differences in glucose metabolism and self-control is sparse, as most previous research has focused on associations between state self-control performance and momentary glucose levels. In two experiments in healthy participants (n = 60, mean age 35.2 ± 13.9, 58% women; n = 103, mean age 25.8 ± 6.3, 67% women) consisting of a baseline assessment and a laboratory session, we examined whether trait markers of glucose metabolism (fasting glucose levels, oral glucose tol…
Validation of the Walking Behavior Questionnaire (WBQ): A tool for measuring risky and safe walking under a behavioral perspective
2020
Abstract Introduction Although daily walking implies several potential benefits for the health and well-being of people, and, besides the raise of more “walkable” cities, it is currently being promoted as an active transportation means that is rich in benefits for its users, road risks affecting pedestrians, together with their high vulnerability to suffer severe injuries as a consequence of traffic crashes, have turned into a relevant concern for both policymakers and public health practitioners. In this regard, risky and positive (proactively safe) behaviors have acquired a substantial relevance for the study and prevention of traffic causalities involving different road users, including …
Relationship of subjective helplessness and pain perception after electric skin stimuli
2000
Objective and subjective controllability of painful stimuli are important factors in pain perception. The present study investigated direct and indirect effects of uncontrollability on perceived pain intensity in humans. Forty-eight healthy male volunteers participated in a laboratory experiment using a reaction time paradigm to induce controllable or uncontrollable feedback conditions in two randomly selected groups. Under controllable conditions, unpleasant electric skin shocks were applied, only when the actual time exceeded an individual threshold; under uncontrollable conditions, skin shocks were applied randomly using a yoked control design. Subjective helplessness, perceived pain int…
Evaluating the statistical methodology of randomized trials on dentin hypersensitivity management
2017
The present study aimed to evaluate the characteristics and quality of statistical methodology used in clinical studies on dentin hypersensitivity management. An electronic search was performed for data published from 2009 to 2014 by using PubMed, Ovid/MEDLINE, and Cochrane Library databases. The primary search terms were used in combination. Eligibility criteria included randomized clinical trials that evaluated the efficacy of desensitizing agents in terms of reducing dentin hypersensitivity. A total of 40 studies were considered eligible for assessment of quality statistical methodology. The four main concerns identified were i) use of nonparametric tests in the presence of large samples…
Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion
2020
This is a pre-print of a published study: Renko, E., Knittle, K., Palsola, M. et al. Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion. BMC Public Health 20, 1568 (2020). https://doi.org/10.1186/s12889-020-09653-x Background: In order to achieve real-world impacts, successful behavior change interventions need to be scaled up and broadly implemented. Implementation is challenging however, and the factors influencing successful implementation are not fully understood. This study describes the nationwide implementation of a complex theory-based program to promote physical activity and reduce sedentary behavior in vocational school…
Real-world EUROCRINE® registry data challenge the reliability of Bethesda cytopathology for thyroid surgery indication
2021
Abstract Objectives Fine-needle aspiration cytology (FNAC) is recommended by international guidelines for the preoperative evaluation of suspicious thyroid nodules >1 cm. Despite robust evidence from endocrine centers demonstrating the key role of FNAC results for the indication of surgery, the method is not routinely used in European clinics. The database EUROCRINE®, which was introduced in 2015 with the scope of registering operations of the endocrine system, allows for a large-scale analysis of the current service reality in Europe concerning FNAC use and associated accuracy. Methods Operations performed to “exclude malignancy”, registered from January 2015 to December 2018 in EUROCRI…
