  • Be autonomous or stay away! Providing evidence for autonomy beliefs as legitimizing myths for the stigma of schizophrenia ( ¡Sé autónomo o mantente al margen! Ofreciendo evidencias para las creencias …

    Open AccessDimitrios Lampropoulos, Themistoklis Apostolidis et al.ARTICLEInternational Journal of Social…2022

    Authors suggest that in liberal contexts, groups considered as lacking autonomy, such as people with schizophrenia, can face stigma. Following Social Dominance theory, we hypothesized that perceived autonomy of people with schizophrenia mediates the relation between SDO and stigmatizing attitudes. Participants from the general population ( N = 255; 76.5% women, Mage = 25.33, SD = 12.3) responded to our questionnaire assessing one’s SDO, perceived…

  • Ideology and the stigma of schizophrenia: Applying the dual‐process motivational model in the French and Greek contexts

    Open AccessDimitrios Lampropoulos, Konstantina Chatzigianni et al.ARTICLEJournal of Community & Applied…2021Cited by: 2References: 7

    The authors have underlined the influence of issues of power and ideology on the stigma of schizophrenia. The dual‐process cognitive‐motivational model of ideology and prejudice has shown that for deviant and derogated groups, such as people with schizophrenia, both authoritarianism and social dominance orientation can predict prejudice. However, this model has not been tested in relation to the stigma of schizophrenia. In this paper, we apply th…

  • Representing the citizenship of mental health users in French mental health policy: A critical analysis of the official French texts on mental health policies since 2005

    Open AccessDimitrios Lampropoulos, Themistoklis Apostolidis et al.ARTICLECritical Social Policy2021References: 31

    Research has shown that mental healthcare policies aimed at achieving autonomy and integration for people with mental disorders have been developing all over the world. Critics working from a governmentality perspective have argued that these changes are associated with broader neoliberal strategies and aims. In France however, there is no systematic work on this development. In this study, we have applied Bacchi’s ‘What’s the Problem Represented…

  • The dynamics of public opinion following terror attacks: Evidence for a decrease in equalitarian values from Internet Search Volume Indices

    Open AccessJais Adam‐troian, Jais Troian et al.ARTICLECyberpsychology Journal of…2019

    The tendency of terror attacks to generate increased right-wing attitudes is a direct prediction from the motivated cognition approach to political ideology (Jost, 2017). However, due to methodological and theoretical problems, evidence for this ‘right-shift’ hypothesis is currently mixed. To address these issues, we introduce for the first-time search volume indices (SVI) analysis to the study of public opinion dynamics by assessing the effects …

  • Evidence for indirect loss of significance effects on violent extremism: The potential mediating role of anomia

    Open AccessJais Adam‐troian, Ouissam Baidada et al.ARTICLEAggressive Behavior2019Cited by: 4References: 66

    Psychological research suggests that violent extremism (e.g., terrorism) stems partly from existential motives, such as individuals’ need to achieve significance in life after experiencing failure, ostracism, or humiliation (Significance Quest Theory; SQT). Parallel investigations from sociology and criminology established similar findings by linking anomia—a syndrome including feelings of meaninglessness, powerlessness, isolation, self‐estrangem…

  • National identification and support for discriminatory policies: The mediating role of beliefs about laïcité in France

    Open AccessJais Adam‐troian, Thomas Arciszewski et al.ARTICLEEuropean Journal of Social…2019Cited by: 3References: 45

    In France, laïcité is a legal principle enforcing State secularism. However, research indicates that Modern (vs. traditional) beliefs about laïcité (ML) help legitimate prejudice against minorities. From Social Identity Theory, we hypothesized that ML should be positively linked with national identification, stereotyping, prejudice and support for discrimination. Accordingly, we demonstrate that ML independently predicts support for discriminator…

  • Behave like a responsible adult” – Relation between social identity and psychosocial skills at stake in self-management of a chronic disease

    David Fonte, Marie-Claude Lagouanelle-Simeoni et al.ARTICLESelf and Identity2017

    We show that the development of psychosocial skills promoting self-management of a chronic disease is associated with the acquisition of a social identity valued in the ideological context of reference. To do this, we focus on a skill that is important for people suffering from a chronic disease to acquire: Assuming responsibility for self-managing one’s own pathology. Because acting responsibly is also a skill socially attributed to the identity…
