This study aims to test the psychometric properties of the Integration of Stressful Life Experiences Scale (ISLES) and examines its associations with psychological distress, satisfaction with life, resilience, and religiosity among individuals affected by the Libyan wars. The sample consisted of 457 participants, with 77.02% female (n = 352) and 22.98% male (n = 105), ranging in age from 18 to 75 years (M_age = 28.82, SD = 11.41). Confirmatory Factor Analysis (CFA) revealed that the one-factor model exhibited excellent fit, with indices: CFI = .997, TLI = .997, RMSEA = .029 (90% CI = [.015, .040]), SRMR = .050. Reliability analysis indicated high internal consistency (ω = .94, α = .94). ISLES scores were negatively correlated with satisfaction with life (r = - .27) and resilience (r = - .39), while correlations with religiosity were non-significant (r = - .09, p = .060). Positive correlations were observed with psychological distress, including anxiety (r = .39), depression (r = .46), and stress (r = .32). Exploratory indirect association analyses showed that ISLES scores were statistically associated with psychological distress through resilience and life satisfaction, whereas no significant indirect association was observed for religiosity. These findings support the one-factor structure of ISLES and highlight context-specific patterns of association in populations exposed to chronic and ongoing trauma
Background The psychological well-being of Egyptian women is shaped by entrenched social, religious, and cultural norms, often resulting in heightened stress and internalized distress. Despite advances in women’s education and activism, empirical work linking everyday sexist discrimination to mental health outcomes in Egypt remains limited. Objectives To assess gender differences in multidimensional psychopathology in Egypt and to examine how the frequency and type of sexist experiences relate to mental health symptom severity among Egyptian women. Design Quantitative, community-based cross-sectional survey. Methods A structured survey was administered to 310 adults—including 195 women—recruited in Cairo and surrounding regions. Validated instruments measured multiple mental health domains (including depression, anxiety, anger, and somatic symptoms) and the frequency of sexist events using the Schedule of Sexist Events. Bonferroni-corrected nonparametric tests and multivariate linear regressions were conducted to evaluate gender differences and associations between sexist discrimination and symptom severity. Results Women reported significantly higher anger, anxiety, and somatic symptoms than men, whereas no other demographic variables predicted symptom burden after correction. Among women, more frequent sexist experiences—particularly sexual degradation and sexism in close relationships—were robustly associated with greater severity across all assessed mental health domains (R2 = 0.307). Conclusion Sexist discrimination emerges as a central determinant of Egyptian women’s mental health, with specific forms of sexism showing strong links to broad psychopathological burden. Policymakers and practitioners should prioritize gender-sensitive prevention strategies, clinical care, and structural reforms to address both public and private sources of sexism-related adversity.
Passion has been involved in psychological processes that emerge in diverse human activities such as physical activity and sports, work, leisure, and interpersonal relationships. As a leisure time activity, few studies have explored the relationships between passion types and subjective well-being for physically active older adults. Two studies were conducted with 1,277 adult runners (642 men; 612 women); age: M = 60.79, SD = 5.32. Study 1 (n = 567; n = 163) aimed to test the psychometric properties of the adapted passion scale. Study 2 (n = 556) aimed (a) to test the mediation of subjective vitality in the relationships among harmonious passion (HP), obsessive passion (OP), and life satisfaction and (b) to test the effect of selected variables on HP and OP. The adapted passion scale had good factorial structure, convergent validity, internal consistency, and temporal stability. It was proved that HP was a positive predictor of vitality, which was a direct positive predictor of life satisfaction, whereas OP was not a significant predictor for vitality and a direct negative predictor of life satisfaction. Vitality was a partial mediator between passion types and life satisfaction. Thus, the adapted passion scale proved to have good psychometric properties and the findings were identical to those of Vallerand and his colleagues.
In Arabic world, few studies are interested in psychological factors influencing the physically activeold adults. The specific goals of the present research are the following: (i) test the factor structureand invariance tests for gender and physical activities for the Arabic version of the passion scale;(ii) test a model that describes a mediator role of subjective vitality in the relationships betweenpassion and life satisfaction (iii) test the presence of differences for gender, physical activity practice,education level and age on passion. Two studies were conducted with 551 physically active gyptian old adult ( n = 354; n = 197). Passion, Subjective vitality and Life Satisfaction scales wereadministered. Passion scale composed of two subscales (harmonious and obsessive). Strong supportfor the complete invariance between groups. Subjective vitality was a mediator in the relationshipsbetween harmonious passion and life satisfaction. Education level and age had an effect on passionsubscales
The specific goals of the present research were twofold: i) to test the structure validity, and internal reliability of scores from the Psychological Flourishing Scale (PFS) with Egyptian college students; and ii) to test the PFS’s temporal stability and convergent validity properties. Two samples of Egyptian college students completed the PFS (n = 374; n = 173) to address the two research aims in two studies. The students also completed the Mental Health Continuum-Short Form (MHC-SF) and the Satisfaction With Life Scale (SWLS) for determining the concurrent validity of scores. In the first study, the internal consistency was evaluated. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed. In the second, the temporal stability and convergent validity were tested. The Arabic version of PFS showed a high internal reliability, structure, and convergent validity, and moderate temporal stability.
Introduction et objectifs Après une étape de validation des questionnaires en langue française de différents besoins fondamentaux (besoin de cognition, de clôture et d’évaluer), nous avons testé dans deux études, l’idée que ces besoins dits fondamentaux pouvaient être assujettis à des contraintes sociales et qu’ils pouvaient être envisagés autrement que comme des caractéristiques stables de la personnalité ou des moteurs motivationnels de l’action. Méthode En utilisant le paradigme des juges (étude 1) et le paradigme de l’identification (étude 2), les résultats plaident en faveur d’une normativité des besoins, tout au moins en ce qui concerne le besoin de cognition et d’évaluer. Résultats Les résultats de la première étude montrent que les individus jugent plus favorablement des cibles présentant de fort besoin plutôt que de faible besoin et ce surtout dans des contextes sociaux à forte utilité sociale (c’est-à-dire le contexte professionnel en comparaison du contexte amical). Les résultats de la seconde étude mettent en évidence que lorsqu’il s’agit de répondre aux questionnaires type des besoins comme le ferait une personne ayant été préalablement bien ou mal évaluée, les participants obtiennent des scores plus élevés sur le besoin de cognition et d’évaluer dans le premier cas que dans le second. Les résultats concernant le besoin de clôture apparaissent plus mitigés. Conclusion Les résultats sont discutés dans une perspective socio-normative. Abstract Introduction and objectives After leading a validation of questionnaires about three fundamental needs in French language (need for cognition, closing and evaluation), we tested in two studies that fundamental needs could be subjected to social constraints and could be considered differently than exclusively like stable personality characteristics and motivational drivers of action. Method Using the paradigm of judges (study 1) and the paradigm of identification (study 2), the results argue for a normative approach, at least as regards the need for cognition and assess. Results The results of the first study show that individuals consider more favorably targets with strong need rather than low need and especially in social contexts with high social utility (that is to say, the professional context in comparison with the friendly context). The results of the second study show that when the questionnaires about needs “as would a person having been previously well or poorly assessed” participants get higher scores high on the need for cognition questionnaire in the first case than in the second. The results regarding the need for closure are more mixed. Conclusion The results are discussed in a socio-normative perspective.
Background: The objectives of this study were to test the factor structure and internal consistency of the 12-item General Health Questionnaire (GHQ-12) and the Subjective Vitality Scale (VS) in elderly French people, and to test the relationship between these two questionnaires. Methods: Using a standard 'forward-backward' translation procedure, the English language versions of the two instruments (i.e. the 12-item General Health Questionnaire and the Subjective Vitality Scale) were translated into French. A sample of adults aged 58-72 years then completed both questionnaires. Internal consistency was assessed by Cronbach's alpha coefficient. The factor structures of the two instruments were extracted by confirmatory factor analysis (CFA). Finally, the relationship between the two instruments was assessed by correlation analysis. Results: In all, 217 elderly adults participated in the study. The mean age of the respondents was 61.7 (SD = 6.2) years. The mean GHQ-12 score was 17.4 (SD = 8.0), and analysis showed satisfactory internal consistency (Cronbach's alpha coefficient = 0.78). The mean VS score was 22.4 (SD = 7.4) and its internal consistency was found to be good (Cronbach's alpha coefficient = 0.83). While CFA showed that the VS was uni-dimensional, analysis for the GHQ-12 demonstrated a good fit not only to the two-factor model (positive vs. negative items) but also to a three-factor model. As expected, there was a strong and significant negative correlation between the GHQ-12 and the VS (r = -0.71, P < 0.001). Conclusion: The results showed that the French versions of the 12-item General Health Questionnaire (GHQ-12) and the Subjective Vitality Scale (VS) are reliable measures of psychological distress and vitality. They also confirm a significant negative correlation between these two instruments, lending support to their convergent validity in an elderly French population. The findings indicate that both measures have good structural characteristics.
En France, l’absence d’une mesure fiable et valide du style attributionnel ou mode explicatif des enfantsa limite´ les investigations dans ce domaine. Le mode explicatif est de´fini par la tendance, ge´ne´rale etstable, d’un individu a` attribuer certaines causes plutoˆt que d’autres, quelles que soient les situations a`l’issue similaire (Peterson & Seligman, 1984). L’objectif du pre´sent article est de valider une versionfranc¸aise du Children’s Attributional Style Questionnaire (CASQ) appele´e : Questionnaire d’e´valuationdu mode explicatif des enfants ou QEMEE. Pour ce faire, les auteurs ont suivi les e´tapes de validationtransculturelle de´finies par Vallerand (1989). Ainsi, un important e´chantillon d’enfants aˆge´s de 9 a` 12 anset de nombreuses analyses statistiques ont permis d’e´valuer les qualite´s psychome´triques de ce ques-tionnaire. Les re´sultats de ces e´tudes re´ve`lent clairement la pre´sence de quatre modes explicatifs chezl’enfant (c.-a`-d. un mode explicatif neutre-bas, optimiste, neutre-haut et pessimiste). Enfin, une versioncourte du QEMEE (c.-a`-d. QEMEE-R) a e´te´ de´veloppe´e. Les re´sultats montrent que cette versionpre´sente des qualite´s psychome´triques satisfaisantes, notamment en ce qui concerne les e´ve´nementsne´gatifs
