The Integration of Social and Neural Synchrony : A Case for Ecologically-Valid Research Using MEG Neuroimaging
2021
The recent decade has seen a shift from artificial and environmentally-deprived experiments in neuroscience to real-life studies on multiple brains in interaction, coordination and synchrony. In these new interpersonal synchrony experiments, there has been a growing trend to employ naturalistic social interactions to evaluate mechanisms underlying synchronous neuronal communication. Here, we emphasize the importance of integrating the assessment of neural synchrony with measurement of non-verbal behavioral synchrony as expressed in various social contexts: relaxed social interactions, planning a joint pleasurable activity, conflict discussion, invocation of trauma, or support giving, and as…
Validity and reliability of the checklist of non-verbal pain indicators in Albanian. First step
2018
Background: in Albania non ci sono strumenti affidabili per valutare la presenza di dolore nei pazienti non-verbalizzanti. L'obiettivo del nostro studio era di fornire una validazione linguistica della checklist in albanese per gli indicatori di dolore non verbale (CNPI). Metodi: dopo la traduzione inversa, abbiamo usato la versione albanese in uno studio trasversale per verificare sia l'affidabilità che la validità di questo strumento in contesti clinici. La Visual Analog Scale è stata adottata come gold standard. Sono stati usati anche il kappa di Cohen e il coefficiente di correlazione di Pearson. La validità costruttiva del CNPI è stata stabilita mediante l'analisi fattoriale esplorativ…
Trans-Contextual Model Predicting Change in Out-of-School Physical Activity: A One-Year Longitudinal Study
2021
The aim of the current study was to test the long-term predictive validity of the trans-contextual model in accounting for variance in adolescents’ out-of-school physical activity measured by self-report and accelerometer based-devices over a one-year period. Secondary school students ( N = 265) aged 11 to 15 years completed a three-wave survey on two occasions in time, spanning a one-year interval, measuring perceived autonomy support in physical education (PE), peer and parent autonomy support in leisure-time, autonomous and controlled motivation in PE and leisure-time, attitude, subjective norms, perceived behavioural control, intention, and out-of-school physical activity both by sel…
L’Outcome-Questionnaire 45.2. Adattamento italiano di uno strumento per la valutazione dei trattamenti psicologici.The Outcome Questionnaire 45.2. It…
2008
Scopo – L’Outcome Questionnaire (OQ-45.2; Lambert et al., 2004) è uno strumento che misura importanti aree di funzionamento psicologico (sintomatologia, problemi interpersonali, funzionamento nel ruolo sociale) di interesse centrale per la valutazione degli esiti psicoterapeutici. In questo studio è stata esaminata la validità cross-culturale dell’OQ-45.2 nella popolazione italiana, confrontando le proprietà psicometriche, l’equivalenza della struttura fattoriale ed i punteggi normativi della versione italiana con quella originale degli USA. Metodo – I dati sono stati raccolti a Bologna e Palermo presso l’Università (N=461), tre strutture pubbliche di salute mentale (N=301) ed un’organizzaz…
Using meta-analytic path analysis to test theoretical predictions in health behavior: An illustration based on meta-analyses of the theory of planned…
2016
Objective Synthesizing research on social cognitive theories applied to health behavior is an important step in the development of an evidence base of psychological factors as targets for effective behavioral interventions. However, few meta-analyses of research on social cognitive theories in health contexts have conducted simultaneous tests of theoretically-stipulated pattern effects using path analysis. We argue that conducting path analyses of meta-analytic effects among constructs from social cognitive theories is important to test nomological validity, account for mediation effects, and evaluate unique effects of theory constructs independent of past behavior. We illustrate our points…
Measuring Internet Gaming Disorder and Gaming Disorder : A Qualitative Content Validity Analysis of Validated Scales
2021
Numerous instruments have been developed to measure gaming-related health problems based on “internet gaming disorder” (IGD) in the third section of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) and “gaming disorder” (GD) in the International Classification of Diseases (11th rev.). However, the criteria in the manuals tend to be operationalized in numerous diverse ways, which can make screening outcomes incomparable. A content validity analysis is needed to reassess the relationships between the diagnostic criteria and the items that operationalize them. The IGD and GD criteria were divided into sematic components. A qualitative content validity analysis was carried ou…
Application of the Chinese Version of the BIS/BAS Scales in Participants With a Substance Use Disorder: An Analysis of Psychometric Properties and Co…
2020
Carver and White developed the Behavioral Inhibition/Behavioral Activation Scales (the BIS/BAS Scales) based on Reinforcement Sensitivity Theory proposed by Gray. Subsequent studies proposed that substance abuse was closely related to Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS). However, researches on the psychometric properties of the BIS/BAS scales in clinical samples are scarce. The present study was conducted to analyze the applicability of the BIS/BAS scales in a sample suffering from a substance use disorder (SUD) and undergoing treatment in compulsory detoxification institutions (n = 1117). Meanwhile, 822 community residents were selected for comparison.…
Initial validation of the Psychobiosocial States in Physical Education (PBS-SPE) scale
2018
The purpose of this cross-sectional investigation was to examine the item characteristics, factor structure, reliability, convergent validity, and nomological validity of the Psychobiosocial States in Physical Education (PBS-SPE) scale. In Study 1, a sample of 1,030 students (582 girls and 448 boys, 10 to 19-year-olds), drawn from middle or high schools, rated the intensity of the 20 items version of the PBS-SPE scale thinking about the feelings they had usually experienced in physical education classes. In Study 2, an additional sample of 1,025 students (578 girls, 447 boys, 10 to 19-year-olds), rated the 16 items of the final version of the scale. Two subsamples also completed an affectiv…
Assessment of Physical and Chemical Stability of Different Magnesium Compounds in Tablets
2020
Modern lifestyle, excessive chemicalization of agricultural products, excessive processing and refining of food, cause a decrease in daily intake of magnesium, cation with an extremely important role in prevention and treatment of many diseases. As a result, there arises the need for extra magnesium intake in the form of dietary supplements. In this study were evaluated the physical and chemical stability of magnesium-containing tablets, depending on the active compound and the excipients used. Magnesium tablets in the form of orotate, lactate, citrate, oxide and hydroxide were taken into study and physical and chemical stability were observed over the validity period, at 6 and at 12 month…
Scienza giuridica, validità e potere in Alf Ross e Herbert Hart
2019
Quella tra Alf Ross ed Herbert Hart è la storia di un amore non corrisposto. Il primo non si lascia sfuggire alcuna occasione per rimarcare quanto la sua concezione del diritto sia, in definitiva, sovrapponibile a quella del secondo il quale, al contrario, giudica con grande severità, unita ad una punta di sarcasmo, la prospettiva giusfilosofica del primo. Gli amori non corrisposti sono senz’altro più interessanti di quelli corrisposti, i quali rischiano di apparire noiosi. In questo saggio cerco dunque di analizzare le ragioni e i fraintendimenti di questa storia d’amore senza lieto fine. Anticipo subito che, sebbene vi siano stati dei fraintendimenti (soprattutto da parte di Hart),vi sono…
