The Importance of Positive Psychological Strengths in Well-Being and Adjustment of Romanian Emerging Adults: A Pattern and Variable-Oriented Approach
2021
Transition to adulthood in countries that have seen recent historical structural changes in society as well as changes in what it means to be an adult represents important contexts for investigations of ways in which positive development and transition to adulthood are experienced. Situated in such context, this cross-sectional study aimed to (1) describe profiles of positive psychological strengths, as measured by the Five Cs of positive youth development (PYD) and (2) document how identified profiles might differ in relation to other aspects of positive and problematic development. Participants were 272 Romanian emerging adults attending university (76% female; aged 19–29 years old, Mage …
Coping with everyday stress and links to medical and psychosocial adaptation in diabetic adolescents.
2003
Abstract Purpose To study coping with everyday stressors in a longitudinal sample of 98 adolescents with insulin-dependent mellitus (type 1) diabetes. Methods The adolescents with type 1 diabetes were classified into three homogeneous groups of metabolic control by latent class analysis, based on annual tests of hemoglobin A1 values. Questionnaires assessing frequent minor stressors as well as ways of coping with these stressors were given annually over the course of 4 years. Latent class analysis revealed three distinctive groups of metabolic control over time. Adolescents who exhibited continuously poor, satisfactory, and good metabolic control. Eighty percent of the adolescents stayed in…
Environmental damage evaluation in a willingness-to-accept scenario: A latent-class approach based on familiarity
2015
In this paper we report on the results of the application of a latent class model that was designed to identify and characterize unobserved preference heterogeneity in the context of a willingness-to-accept (WTA) framework involving negative environmental externalities stemming from the expansion of the Port of Valencia. We investigated the hypothesis that respondents with greater familiarity with the targeted good and any related environmental damage would demand more compensation; that is, they would have a significantly higher WTA. Based on respondents' familiarity with the Port of Valencia and their pre-existing knowledge about the negative consequences of its potential expansion three …
Understanding maritime transport route choice among Irish exporters: A latent class approach
2021
Abstract The reduction in the level of maritime connectivity between Ireland and mainland Europe has been the focus of concern for Irish exporters since the withdrawal of the United Kingdom from the European Union in January 2019. In a post-Brexit scenario, new proposals are being sought to address Ireland's reliance on the UK land-bridge. Policy developments aimed at circumventing the potential negative impact of UK customs checks for Irish exports include the proposals by the European Commission to introduce new direct shipping routes connecting main ports in Ireland with Zeebrugge and Antwerp in Belgium, as well as with Rotterdam in the Netherlands. From a transport policy perspective, f…
Valuing public acceptance of alternative-fuel buses using a Latent Class Tobit model: A case study in Valencia
2020
Abstract The introduction of hybrid electric technology for urban public transportation can be considered a valuable stepping stone to low-carbon mobility. Using the contingent valuation method, a sample of 427 respondents were asked about their willingness to pay for the air pollution reductions associated to a scenario of gradual introduction of hybrid electric buses in Valencia, Spain. Results show that 67% of the respondents are willing to pay extra for the adoption of this electric hybrid technology, being the mean willingness to pay € 0.33 per single bus fare. This would imply a 22% hypothetical increase in current bus fares and shows that public acceptance is critical for the success…
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 …
Mixture Hidden Markov Models for Sequence Data: The seqHMM Package in R
2019
Sequence analysis is being more and more widely used for the analysis of social sequences and other multivariate categorical time series data. However, it is often complex to describe, visualize, and compare large sequence data, especially when there are multiple parallel sequences per subject. Hidden (latent) Markov models (HMMs) are able to detect underlying latent structures and they can be used in various longitudinal settings: to account for measurement error, to detect unobservable states, or to compress information across several types of observations. Extending to mixture hidden Markov models (MHMMs) allows clustering data into homogeneous subsets, with or without external covariate…
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 Effect Of Supplemental Insurance On Health Care Demand With Multiple Information: A Latent Class Analysis
2009
The Medicare program, which provides insurance coverage to the elderly in the United States, does not protect them fully against high out-of-pocket costs. For this reason private supplementary insurance, named Medigap, has been available to cover Medicare gaps. This paper studies how Medigap affects the utilization of health care services. The decision to take out supplemental insurance is likely to be infuenced by unobservable attributes such as actual risk type and insurance preferences. Empirical appraisals to this problem typically rely on the recursive bivariate probit. We exploit the Health and Retirement Study data and some recent advances on latent class analysis to jointly model th…
