Le but principal de cette thèse est d'explorer le sentiment d'amour passionnel dans les relations romantiques. L'amour passionnel est définit comme « un état de désir intense à d'union avec un autre ». Ce construit est généralement considéré comme une expérience universelle fortement associée à l'attraction sexuelle et possédant un impact considérable sur les dimensions émotionnelles, cognitives et comportementales. Le but principal de cette thèse était d'apporter de nouveaux éléments montrant que les expériences subjectives de l'amour passionnel sont culturellement et contextuellement déterminées et qu'il existe néanmoins une certaine universalité des cognitions et comportements lorsque les personnes déclarent être amoureuses. De plus, nous avons étudié l'effet de l'amour passionnel sur les processus cognitifs. Au total, 1000 étudiants ont participé à 4 études différentes. Des sujets français et brésiliens ont répondu à l’Échelle d'Amour Passionnel (PLS) dans le but d'étudier leurs sentiments d'amour passionnel sur la base des composantes cognitive, émotionnelle et comportementale. Les représentations sociales de l'amour passionnel de ces mêmes groupes ont été explorées à partir d'analyses structurelles d'associations de mots. Les processus cognitifs de l'amour passionnel ont été testés dans une étude sur la relation entre l'amour passionnel et les expériences sensorielles et une étude sur l'effet de l'amour passionnel sur les productions créatives. Les résultats obtenus avec la PLS ont montré les mêmes propriétés psychométriques en France et au Brésil. Dans les deux cas, l'analyse factorielle a révélé une composante principale avec des consistances internes élevées. Les sujets qui ont déclaré être amoureux ont semblé aimer avec le même niveau de passion dans les deux cultures mais des différences de genre ont été retrouvées au Brésil. L'analyse des associations de mots a indiqué des différences contextuelles, culturelles et de genre. En ce qui concerne les processus cognitifs, l'amour passionnel a un effet positif sur l'attraction physique et l'expérience sensorielle mais nous n'avons pas trouvé de relation entre l'amour passionnel et la créativité (pensées divergentes et convergentes). Les résultats de ces différentes études sont présentés et discutés en s'appuyant sur les perspectives interculturelle, neuropsychologique et évolutionniste de l'amour romantique. L'amour passionnel peut être vécu de plusieurs façons mais ses manifestations sont universelles. Nous concluons que l'amour passionnel est principalement un phénomène biologique qui peut être influencé par la culture, assurant des reproductions réussies de notre espèce. / The main goal of this thesis is to explore the romantic feelings of passionate love widely defined as a state of longing with another. This construct is generally considered to be a universal experience strongly associated with sexual arousal and capable of having a strong effect in emotional, cognitive and behavioral dimensions. The main goal of this project is to provide further evidence about the contention that although subjective experiences of passionate love are culturally and contextually determinate, people all over the world present the same symptoms of passionate love with the same intensity when they consider being in love. Plus, the influences of passionate love on cognitive processes were tested in other studies. A total of 1000 college students participated in 4 different studies. The Passionate Love Scale (PLS) was administrated on Brazilian and French subjects in order to explore their evaluation of passionate love through cognitive, emotional and behavioral components. The social representations of these same groups about passionate love were explored with a structural analysis of word associations. Cognitive processes were tested through one study about the relationship between passionate love and sensory experience and another one about the effect of passionate love in creative productions. The results found with the PLS indicated the same psychometric properties in France and in Brazil. In both cases, the factorial analysis indicated one stronger dimension with high internal consistencies. Subjects in love seemed to love with equal passion in both cultures but gender differences were found in Brazil. The analysis of the word association revealed contextual, cultural and gender differences. Passionate love had a positive effect in low cognitive processes (physical attraction and sensory experience) but no effect in high cognitive tasks (divergent and convergent thinking). The results of these different studies are presented and discussed in the light of cross-cultural, neuropsychological and evolutionary perspectives on romantic love. Passionate love might be experienced in a number of ways but its manifestation is universally the same. It is concluded that passionate love might be mainly a biological phenomenon with minor cultural variations directed to insure reproductive success in our species.

Following Snyderman and Rothman (1987, 1988), we surveyed expert opinions on the current state of intelligence research. This report examines expert opinions on causes of international differences in student assessment and psychometric IQ test results. Experts were surveyed about the importance of culture, genes, education (quantity and quality), wealth, health, geography, climate, politics, modernization, sampling error, test knowledge, discrimination, test bias, and migration. The importance of these factors was evaluated for diverse countries, regions, and groups including Finland, East Asia, sub-Saharan Africa, Southern Europe, the Arabian-Muslim world, Latin America, Israel, Jews in the West, Roma (gypsies), and Muslim immigrants. Education was rated by N = 71 experts as the most important cause of international ability differences. Genes were rated as the second most relevant factor but also had the highest variability in ratings. Culture, health, wealth, modernization, and politics were the next most important factors, whereas other factors such as geography, climate, test bias, and sampling error were less important. The paper concludes with a discussion of limitations of the survey (e.g., response rates and validity of expert opinions).

ABSTRACT Depression is one of the oldest known mental health conditions. It is acknowledged to be a global health problem that affects people from any culture or ethnic group. The prevalence of depression widely varied across countries and cultures. The cross-cultural relevance of the concept of depression, its screening or diagnosis, and cultural equivalence of items used to measure symptoms of depression has been area of research interest. Differences in prevalence rates in depression have been suggested as being due to research artifacts, such as use of instrument developed for one culture to another culture. With the current trend of globalization and increased rate of immigration, the need for measurement scales that can be used cross-culturally is becoming essential. Translation and adaptation of existing tools to different languages is time saving and cost effective than developing a new scale. The Center for Epidemiologic Studies Depression Scale [CES-D; (Radloff, 1977)] has been widely used as a screening tool for depressive symptoms in community and clinical settings. It has been widely accepted and translated to multiple languages and its measurement equivalence tested across groups. This study was designed as a mixed method study. The purpose of this study was three fold: (a) translate and adapt the CES-D scale into Tigrigna Language for use by Tigrigna speaking Eritrean immigrants in the United States using the forward backward translation and cognitive interview techniques (b) test the psychometric properties of the Tigrigna version CES-D scale using confirmatory factor analysis under the framework of structural equation modeling and (c) test measurement equivalence of the scale by comparing data collected from 253 Eritrean immigrants using the Tigrigna version CES-D scale with a secondary data collected from 1918 non Eritrean US citizens using the English version CES-D scale in a separate study. The baseline four factor CES-D scale model originally suggested for the general population fitted the data from both samples. The fit indices for the Tigrigna sample were (χ2 = 299.87, df = 164, RMSEA = .06, SRMR = .06, GFI = .89, and CFI = .98) and for the English sample (χ2 = 1496.81, df = 164, RMSEA = .07, SRMR = .04, GFI = .92, and CFI = .98). The Multi-group confirmatory factor analysis showed reasonably adequate fit (χ2 (328) = 1796.68, RMSEA= .07, SRMR = .06, GFI = .89, CFI = .98). Fourteen of the 20 CES-D items were invariant across the two samples suggesting partial metric invariance. Partial full factor invariance was also supported. In conclusion, the findings of this study provide adequate evidence in support of the applicability of the four factor CES-D scale for measuring depressive symptoms in Tigrigna speaking Eritrean immigrants/refugees in the United States.
