The Reinforcement Sensitivity Theory of Personality Questionnaire (RST-PQ) originated from the Revised Reinforcement Sensitivity Theory of Personality. This study was conducted to assess the psychometric properties of the Persian version of the RST-PQ among a group of Iranian adults. The cross-sectional study was carried out among 600 Iranian adults utilizing a convenient sampling method, following specific participant selection criteria to enhance the study methodology's transparency (including the age range between 18 and 35 years' participants without major psychiatric diagnoses). Participants completed both the Iranian version of the Reinforcement Sensitivity Theory Personality Questionnaire (RST-PQ) and the Five-Factor NEO-FFI questionnaire. Confirmatory factor analysis, employing the multiple indicators model (MIMIC) approach, was utilized in this study to control for demographic variables such as age and gender. The confirmatory factor analysis results showed an acceptable fit of the proposed six-factor model based on the English version of RST-PQ (CFI = 0.905; RMSEA = 0.053). Also, Cronbach's alpha values confirmed the internal consistency of the proposed structure. In addition, competing models were also used to select the best-proposed model. In this way, different models were evaluated, assuming a change in the correlation intensity between BIS and the Fight-Flight-Freeze System (FFFS). The convergent validity results with the Five-Factor Personality measure provided further support and were consistent with previous research findings. It is crucial to have an Iranian-language version of the RST-PQ to promote RST research and show how this theoretical framework aids in explaining and predicting various actions, whether they are abnormal or healthy.

This study aimed to assess the validity of the Mental Health Continuum-Short Form (MHC-SF) as a measure of mental health among Arabic-speaking North African populations. The study had three objectives: (1) to evaluate the structural validity of the MHC-SF and the Subjective Vitality Scale (SVS); (2) to examine measurement invariance across gender and between Moroccan and Egyptian participants; and (3) to assess whether emotional, social, and psychological well-being dimensions predict subjective vitality. A total of 301 psychology students were recruited from Morocco and Egypt. Using CFA, a three-factor model for the MHC-SF demonstrated good structural validity and the SVS showed good fit, as well. Significant correlations between subjective vitality and mental health were observed, and the regression analysis revealed that mental health factors predicted subjective vitality. The findings support the use of the MHC-SF in Arabic-speaking populations and underscore the relevance of cultural context in assessing mental health.

Self-compassion is increasingly recognized as a core psychological resource within contemporary happiness and well-being research, particularly from a psychological perspective emphasizing optimal functioning, resilience, and personal growth. Using a cross-sectional design, this study examines the associations between self-compassion and indicators of psychological well-being (flourishing, hope, resilience, life satisfaction) as well as psychological distress and test an indirect effect model in which resilience mediated the relationship between self-compassion and positive well-being outcomes. A total of 318 Saudi Arab adults completed measures of self-compassion, flourishing, hope, resilience, life satisfaction, and psychological distress. Results supported the theorized six-factor structure of the Self-Compassion Scale–Short Form and showed that self-compassion was positively associated with flourishing, hope, resilience, and life satisfaction, and negatively associated with psychological distress. Structural equation modeling indicated that resilience exerted a significant indirect effect in the relationships between self-compassion and flourishing, life satisfaction, and hope. These findings are consistent with theoretical perspectives in positive psychology and self-compassion theory, suggesting that resilience functions as a key psychological mechanism linking self-compassion to well-being. From a practical perspective, the results highlight the potential value of interventions aimed at enhancing self-compassion and resilience to promote psychological well-being in Arab populations, particularly in clinical and educational settings.
