Fam Process 2021 May 3. Epub 2021 May 3.

School of Psychology, University of Queensland, St. Lucia, Qld, Australia.

Couple relationship standards (beliefs about what makes for a satisfying couple relationship) have not included standards held about religion, which is surprising given how important religion is in many parts of the world. In the current study, we developed the Importance of Religion in Couple Relationships Scale (IRCRS) with the aim of having a scale suitable for use across different cultural and religious groups. The IRCRS was administered to three samples: 354 Pakistani residents (178 females, 176 males) who identified as Muslim; 274 Thai residents (157 females, 117 males) who identified as Buddhist; and 165 Westerners (resident in Australia or the United States, 60 males, 105 females) who identified as either not religious (n = 74) or Christian (n = 91).

Emotional Labour and Work-Family Conflict in Voice-to-Voice and Face-to-Face Customer Relations: A Multi-Group Study in Service Workers.

Eur J Psychol 2020 Nov 27;16(4):542-560. Epub 2020 Nov 27.

Department of Psychology, University of Turin, Turin, Italy.

Professions that involve interaction with customers entail great emotional effort: workers are required to show emotions different from their true feeling and they experienced emotional dissonance and verbal aggression from customers. These job demands can generate discomfort and the effects of emotional labour can "expand" in other life domains. The study investigated the relationship among emotional dissonance, customer verbal aggression, affective discomfort at work and work-family conflict, considering differences between two groups of service workers: call centre agents (CA; N = 507, voice-to-voice relation with customers) and supermarket cashiers (SC; N = 444, face-to-face relation with customers).

Perceived discrimination and contextual problems among children and adolescents in northern Chile.

PLoS One 2021 19;16(2):e0246998. Epub 2021 Feb 19.

Departamento de Psiquiatría, Facultad de Medicina, Hospital Clínico Universidad de Chile, Santiago, Región Metropolitana, Chile.

Discriminatory behaviors among inter-ethnic relations in schools have long been noted and studied, but there are several correlations between discriminatory behaviors and other constructs that need further investigation. As an example, the relation between perceived discrimination and contextual problems-which include family, school and peer problems-among children and adolescents in Latin America has received little attention from previous studies. Further, the mediating role of ethnic identification and collective self-esteem in this relation also needs to be considered as they could be proven as protective factors for discriminatory behavior and its outcomes.
