Understanding complaint channel usage in multichannel retailing
2019
Abstract This study aims to understand customer patterns of channel usage to voice complaints to multichannel retailers. Data were collected from multichannel shoppers for apparel in Spain by means of an online survey. Latent Class Analysis on complaint channel (store, website, mobile app and social media) usage was performed. The analysis identifies four customer segments that use complaint channels differently. Channel dependencies emerged, particularly related to mobile app usage. The study then explores how the identified patterns are related to channel usage for information search and purchase and to the quality of the relationship with the retailer. Results provide theoretical and man…
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 …

Adjustment disorder as proposed for ICD-11: Dimensionality and symptom differentiation
2014
Although Adjustment Disorder as a diagnostic category is widely used in clinical practice it is critically discussed that it has not been conceptualized as a category with unique symptoms. Hence, the conceptualization of Adjustment Disorder is subject to substantive change in ICD-11 including core symptoms and additional features in a uni-faceted concept. Adjustment Disorder was assessed with a self-rating instrument in a representative sample of the German general population (N=2512). Confirmatory factor analyses (CFA) were applied to test the dimensionality of symptoms according to the new diagnostic concept. Latent class analysis (LCA) was applied to test whether there are distinguishabl…
Typical symptom change patterns and their predictors in patients with social anxiety disorder: A latent class analysis
2020
Abstract Objectives The use of trajectories and analysis of change patterns is a promising way toward better differentiation of subgroups in psychotherapy studies. Research on change patterns in social anxiety disorder (SAD) are still rare, although SAD is one of the most common mental disorders. In a secondary analysis of data from the SOPHO-NET-trial (ISRCTN53517394) this study aimed to investigate change patterns and their predictors in a sample of SAD patients. Methods Patients with SAD (N = 357) were randomly assigned to cognitive-behavioral or psychodynamic therapy. The Liebowitz Social Anxiety Scale (LSAS) was assessed at 1st session (pre), 8th session, 15th session and at the end of…
A Measure of Trust: The Italian Regional Divide in a Latent Class Approach
2017
Social differences within countries may partly explain the lack of economic convergence and the persistence of regional disparities. The case of Italy is emblematic: economic gap between North and South remains at high levels with large differences in social capital and in trust. In this paper, we use the micro data from the ISTAT “Aspects of Daily Life” Survey to build a measure of “trust in others” and a measure of “trust in institutions” through a latent class model to attribute a trust score to the Italian households and the Italian regions and, in this way, to add elements of knowledge useful to policies. Our measures confirm a persistent territorial divide although the regional mappin…
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 …
Latent class identification in wheezing preschool children
2016
Background and aim Since the forced oscillation technique (FOT) has not been used in previous studies on wheezing phenotyping in preschool children, we applied FOT in a large series of outpatients visited at IBIM. Methods We analyzed 256 consecutively enrolled ≤5 years children with doctor diagnosis of wheezing. Latent Class Analysis (LCA) was performed considering the following personal characteristics: type, cause, recurrence in last 12 months, respiratory resistance (Avr_R(8)), atopy, history of eczema, rhinitis and upper airways infections. High resistance is defined as positive residual of regression on sex, age, height and weight. Risk factors were considered meaningful when they yiel…
Do shippers’ characteristics influence port choice criteria? Capturing heterogeneity by using latent class models
2022
Abstract This paper focuses on the study of Spanish ceramic tile exporters' port choice criteria, an industry that is characterized by a low unit value index. Thus, transport costs highly influence the competitiveness of their products in international markets, representing a relatively high percentage of the value of the shipment. It is therefore critical for this type of industry to have access to efficient door-to-door maritime chains. Determinants of port choice are analysed through a latent class model allowing to link class membership to specific characteristics of the shippers and their shipments such as the size of the company, the value of the shipment, the destination market and t…
Heterogeneity in general practitioners’ preferences for quality improvement programs: a choice experiment and policy simulation in France
2016
International audience; Despite increasing popularity, quality improvement programs (QIP) have had modest and variable impacts on enhancing the quality of physician practice. We investigate the heterogeneity of physicians’ preferences as a potential explanation of these mixed results in France, where the national voluntary QIP – the CAPI – has been cancelled due to its unpopularity. We rely on a discrete choice experiment to elicit heterogeneity in physicians’ preferences for the financial and non-financial components of QIP. Using mixed and latent class logit models, results show that the two models should be used in concert to shed light on different aspects of the heterogeneity in prefer…
