Psychometric properties of the Problematic Use of Social Networks (PUS) scale in Arabic among adolescents.

BACKGROUND: The Problematic Use of Social Networks (PUSN) scale assesses for the first time the comparative use of social networks along with addictive tendencies. However, it has only been validated in a Spanish sample. This study aimed to evaluate the psychometric properties of the Arabic version of the PUSN (PUSN-Ar) among Lebanese adolescents. METHODS: A total of 379 adolescents aged between 15 to 18 years (M = 16.07 years; 64.9% females) participated in this cross-sectional study conducted between January and May 2022. The problematic use of social networks-SNS (PUSN) scale yields of two subscales: addiction-related consequences of SNS use (SNS-ARC) and negative social comparison (SNS-NSC). The Beirut Distress Scale, the Smartphone Addiction Scale and the Jong-Gierveld Loneliness Scale were used to assess psychological distress, smartphone addiction and loneliness respectively. RESULTS: The PUS-Ar scale exhibited a two-dimensional structure (Comparative Fit Index [CFI] = .97; Root Mean Square Error of Approximation [RMSEA] = .08), consistent with the original scale. Both subscales, Negative Social Comparison (α = .96) and Addictive Consequences (α = .92), demonstrated excellent reliability. Additionally, measurement invariance was verified between males and females at the configural, metric and scalar levels. No significant difference was found between males and females in terms of SNS-NSC (20.75 ± 10.15 vs 21.09 ± 9.51; t(377) = -.32; p = .751) and SNS-ARC (19.08 ± 8.61 vs 19.76 ± 6.77; t(377) = -.79; p = .430). The SNS-ARC subscale was more correlated to smartphone addiction than the SNS-NSC (r = .73; p < .001 vs r = .54; p < .001) whereas both subscales were significantly associated with more stress and more loneliness. CONCLUSION: The data collected in this study provided support for all the hypotheses formulated. Consequently, the PUS-Ar was deemed a suitable scale to measure problematic SNS among Lebanese adolescents. The PUS-Ar is currently available to researchers for use in evaluating PSNSU in Lebanon. However, it is important to note that further research is needed to explore its applicability and generalizability across different populations and contexts.

Validation of the pathological narcissistic inventory (PNI) and its brief form (B-PNI) in the Arabic language.

BACKGROUND: The Pathological Narcissism Inventory (PNI) is a multidimensional measure developed to assess narcissistic grandiosity and narcissistic vulnerability. We aimed to validate the Arabic version of the original Pathological Narcissistic Inventory (PNI) and its brief form (B-PNI) in a community sample of Lebanese adults. METHODS: The English language PNI items were translated into Arabic following a rigorous translation, back-translation, and linguistic evaluation. A total of 401 participants were administered the translated PNI, as well as previously validated Arabic versions of the Big Five Inventory-2, the Rosenberg Self-esteem Scale, the Patient Health Questionnaire (PHQ-9), and the Impulsivity-8 Scale. RESULTS: Exploratory and confirmatory analyses supported the existence of seven first-order and two second-order factors of the PNI and B-PNI. Except for exploitativeness where females scored lower than males, no other significant differences by gender were observed for the remaining PNI subscale scores. Additionally, scores on all the subscales exhibited good reliability, while the associations with external measures supported the concurrent validity of the translated instrument. CONCLUSION: The results of this study suggest that scores on the PNI and B-PNI are highly reliable with satisfactory concurrent and factorial validity, providing an assessment of broadly defined pathological narcissism among the Lebanese young adult population. The availability of the Arabic PNI and its brief form should facilitate improved understanding of pathological narcissism in Arabic cultures and the different factors that govern narcissistic personality pathology.

Psychometric properties of an Arabic translation of the Functionality Appreciation Scale (FAS) in Lebanese adults.

The Functionality Appreciation Scale is a widely used instrument for the measurement of an individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). Here, we examined the psychometric properties of a novel Arabic translation of the FAS. A sample of 826 Lebanese adults completed the FAS, as well as previously validated measures of body appreciation, disordered eating attitudes, orthorexia, and self-esteem. Exploratory and confirmatory factor analyses supported a unidimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, with women reporting significantly greater functionality appreciation than men. FAS scores were found to have adequate composite reliability and adequate patterns of convergent and criterion-related validity. Additionally, functionality appreciation predicted self-esteem once the effects of all other variables had been accounted for, supporting incremental validity. Overall, these results suggest that the Arabic FAS is a psychometrically valid tool for the assessment of functionality appreciation. The availability of the Arabic FAS should facilitate improved understanding of the effectiveness of existing interventions designed to promote greater physical activity in the Lebanese context.
