Empirically-derived subgroups of Facebook users and their association with personality characteristics: a Latent Class Analysis

2018

Abstract In recent years, considerable research effort has been directed at the identification of relationships between psychological variables and Facebook usage indicators. However, the identification of homogeneous subgroups of individuals based on similar Facebook usage characteristics still presents a challenge. This study aims: (1) to empirically determine homogeneous groups of Facebook users based on variables regarding their personal experience on Facebook, by using a Latent Class Analysis; and (2) to examine the association between an individual's personality and interpersonal characteristics and the empirically-derived profiles of Facebook usage. Eight hundred and eleven Facebook …

FACEBOOK ADDICTION? UNO STUDIO SU STILI RELAZIONALI E CARATTERISTICHE DISFUNZIONALI IN SOGGETTI CON DIVERSE TIPOLOGIE DI UTILIZZO DEL SOCIAL NETWORK

Background: Previous studies on individual characteristics related to Facebook usage seems to support that active Facebook users are more likely to be higher in attachment anxiety or in extraversion, but specific interpersonal profiles of individual’s Facebook usage are still missing in the literature. The aims of the current study were: a) to investigate whether there is a specific interpersonal profile of Facebook users, and b) to explored the contribution of participants’ personality and interpersonal relationship characteristics on their profile group membership. Methods: We investigated a group of 811 subjects (aged from 17 to 61 years) with questionnaires measuring personality traits,…

Motives to practice exercise in old age and successful aging: A latent class analysis.

2018

Abstract Purpose The aim was to classify motives for exercising trying to find sets of related cases that share common motivations, and to relate these latent classes to markers of successful aging. Methods 725 old adult aged 55 to 97 years were sampled in several Spanish towns. Instruments: Successful Aging Inventory (SAI), International Physical Activity Questionnaire (IPAQ), Health Survey SF-8, Satisfaction with Life Scale (SWLS), and motives to practice exercise, were used. Latent Class Analyses (LCAs) were estimated. The classes obtained were compared on markers of successful aging. Results Three latent classes were deemed optimal. Significant differences for several markers of success…

The reasoned action approach applied to health behavior: Role of past behavior and tests of some key moderators using meta-analytic structural equati…

2018

Abstract Rationale The reasoned action approach (RAA) is a social cognitive model that outlines the determinants of intentional behavior. Primary and meta-analytic studies support RAA predictions for multiple health behaviors. However, including past behavior as a predictor in the RAA may attenuate model effects. Direct effects of past behavior on behavior may reflect non-conscious processes whereas indirect effects of past behavior through social cognitive variables may represent reasoned processes. Objective The present study extended a previous meta-analysis of the RAA by including effects of past behavior. The analysis also tested effects of candidate moderators of model predictions: be…

Frailty Status Typologies in Spanish Older Population: Associations with Successful Aging

2020

Background: Defining frailty typologies would contribute to guiding specific care interventions. These typologies could additionally be related to different health outcomes. This study aims at identifying subgroups of frail older adults based on the physical frailty phenotype and examining the relationships of these frailty profiles with quality of life and perceived health. Methods: This study relies on data from the SHARE project, namely a representative sample of 1765 Spanish-dwelling older adults identified as frail or pre-frail. Analysis included general descriptive statistics, exploratory latent class analysis (LCA) to determine the number of frailty subgroups, and LCA with covariates…

Identification of bronchiolitis profiles in Italian children through the application of latent class analysis

2020

AbstractBackgroundBronchiolitis is the primary infection of the lower respiratory tract in children under 2 years of age. Although it is generally considered a single nosological entity, recent studies suggested remarkable clinical heterogeneity. To date, no studies have identified classes of children with bronchiolitis within the Italian population. This study aimed to identify discrete profiles of Italian children hospitalized with bronchiolitis using a clustering approach and to compare findings with those obtained in international cohorts.MethodsThis was a retrospective single-centre study conducted on children aged ≤2 years hospitalised with bronchiolitis (n = 401) at the Department of…

Profiles of Internet Use and Health in Adolescence : A Person-Oriented Approach

2021

(1) Background: Internet use has become an integral part of adolescents’ daily lives. It is important to understand how adolescents use the internet, and how this use is associated with demographic factors and health from a person-oriented perspective. (2) Methods: The study applied the Finnish nationally representative HBSC data (persons aged 11, 13, and 15, n = 3408), descriptive observation, latent class analysis, and multinomial logistic regression analysis. (3) Results: Entertainment activities (listening to music) and socially oriented activities (liking posts, talking online) were the most prevalent among adolescents, but gender differences emerged. Five different internet user profi…

Validity and Internal Consistency of the Preschool-FLAT, a New Tool for the Assessment of Food Literacy in Young Children from the Training-To-Health…

2020

Background: The importance of assessing “food literacy” since youth has been highlighted and, to this purpose, valid and consistent instruments are needed. This study aimed to assess the validity and internal consistency of the preschool-FLAT (Food Literacy Assessment Tool). Methods. 505 children from 21 kindergartens, recruited within the Training-to-Health Project in Palermo (Italy), underwent oral sessions and activities on food-related aspects. Their knowledge/skills were recorded in the preschool-FLAT. The following scale measures were assessed: Content validity; internal consistency (Chronbach’s alpha coefficients); construct validity (Structural Equation Modeling&md…

Barriers and incentives for Italian paediatricians to become smoking cessation promoters: a GARD-Italy Demonstration Project

2020

Background: Paediatricians rarely devote any time to screening and treatment for parental tobacco use. The present project is part of a Global Alliance against Chronic Respiratory Diseases (GARD)-Italy Demonstration Project, aimed to increase the skills of primary care physicians and paediatricians as "promoter of smoking cessation". The aims of this study were: (I) to identify latent classes of barriers and incentives for smoking cessation counseling among paediatricians using latent class analysis (LCA); (II) to investigate risk factors for inclusion into the identified classes. Methods: In 2018, 1,500 Italian paediatricians were invited to complete an online survey on passive smoke expos…
