Psychometric Properties of the Bergen Social Media Addiction Scale in Korean Adolescents

초록

Background: The Bergen Social Media Addiction Scale (BSMAS) is a self-report scale used to measure the severity of social media addiction symptoms. Although the BSMAS has been validated and proven to be reliable in Korean adults, few studies have examined its psychometric properties in Korean adolescents. Therefore, the aim of this study was to confirm the validity and reliability of the BSMAS in Korean adolescents.Methods: The BSMAS, the Social Media Addiction Proneness Scale (SMAPS), and the Social Network Site Use Motives Scale-Revised (SUMS-R) were administered to a cohort of 296 Korean adolescents. Confirmatory factor analysis (CFA) was performed to examine the construct validity. Internal consistency and convergent validity were examined. Additionally, measurement invariance tests across gender and age were conducted.Results: The modified one-factor model exhibited a good model fit. The BSMAS showed statistically significant correlations with all eight subscales of the SUMS-R and with the SMAPS, confirming convergent validity. The BSMAS showed high Cronbach's alpha, and its items showed acceptable item-total correlations. Measurement invariance testing across genders confirmed configural and metric invariance, but scalar invariance was not achieved. In contrast, the measurement invariance test across age groups demonstrated stronger evidence of invariance.Conclusions: These results suggest that the BSMAS is a useful tool for assessing social media addiction in Korean adolescents and provide preliminary evidence of its validity in this population. However, the failure to confirm scalar invariance emphasizes that gender-specific comparisons should be interpreted with caution. Antecedentes: La Escala de Adicci & oacute;n a las Redes Sociales de Bergen (BSMAS) es una escala de autoinforme utilizada para medir la gravedad de los s & iacute;ntomas de adicci & oacute;n a las redes sociales. Aunque la BSMAS ha sido validada y ha demostrado ser fiable en adultos coreanos, pocos estudios han examinado sus propiedades psicom & eacute;tricas en adolescentes coreanos. Por lo tanto, el objetivo de este estudio fue confirmar la validez y fiabilidad de la BSMAS en adolescentes coreanos.M & eacute;todos: Se administraron el BSMAS, la Escala de Propensi & oacute;n a la Adicci & oacute;n a las Redes Sociales (SMAPS) y la Escala de Motivos de Uso de Redes Sociales Revisada (SUMS-R) a una cohorte de 296 adolescentes coreanos. Se realiz & oacute; un an & aacute;lisis factorial confirmatorio (AFC) para examinar la validez del constructo. Se examinaron la consistencia interna y la validez convergente. Adem & aacute;s, se realizaron pruebas de invariancia de medici & oacute;n seg & uacute;n g & eacute;nero y edad.Resultados: El modelo modificado de un solo factor mostr & oacute; un buen ajuste al modelo. La BSMAS mostr & oacute; correlaciones estad & iacute;sticamente significativas con las ocho subescalas de la SUMS-R y con la SMAPS, lo que confirma la validez convergente. La BSMAS mostr & oacute; un alto alpha de Cronbach, y sus & iacute;tems mostraron correlaciones aceptables entre los & iacute;tems y el total. La prueba de invarianza de la medici & oacute;n entre g & eacute;neros confirm & oacute; la invarianza configuracional y m & eacute;trica, pero no se logr & oacute; la invarianza escalar. Por el contrario, la prueba de invariancia de medici & oacute;n en los distintos grupos de edad demostr & oacute; una evidencia m & aacute;s fuerte de invariancia.Conclusiones: Estos resultados sugieren que la BSMAS es una herramienta & uacute;til para evaluar la adicci & oacute;n a las redes sociales en adolescentes coreanos y proporcionan pruebas preliminares de su validez en esta poblaci & oacute;n. Sin embargo, el hecho de no haber podido confirmar la invarianza escalar pone de relieve que las comparaciones espec & iacute;ficas por g & eacute;nero deben interpretarse con cautela.
