To validate the Social Media Disorder scale in Nigerian adolescents by determining its unidimensional structure, reliability, sensitivity, specificity, and criterion validity.
A total of 516 and 1213 pre-university students in two universities were randomly recruited and assessed using the 9-item Social Media Scale and the 12-item General Health Questionnaire (in the second survey only).
46.3% and 56.3% of respondents in the first and second surveys met the criteria for social media disorder, respectively. Factor loading of items on the latent factor (addiction) was moderate. The model yielded a fairly acceptable fit in both samples. The averaged measure for intra-class correlation was acceptable (0.612). The internal consistency (Cronbach's alpha) was good (0.713 for sample 1 and 0.724 for sample 2). The test-retest reliability among the 113 respondents was good (r=0.696, p<0.001). The item-total correlations were all significant. Sensitivity of each item ranged from 67.7% (tolerance) to 91.3% (escape); specificity of each item ranged from 41.2% (escape) to 87.6% (displacement). For criterion validity, the total Social Media Disorder scale score correlated with General Health Questionnaire items that assess self-esteem, depression, and mood, as well as the total score.
The 9-item Social Media Disorder scale is acceptable for screening social media disorder in pre-university students in Nigeria. The high prevalence of social media disorder should be of concern to counsellors, teachers, and mental health practitioners. Strategies for public health education on social media use are needed in Nigeria.
通过确定其单一维度结构、信度、灵敏度、特异性和标准效度，验证尼日利亚青少年社交媒体障碍量表。
在两所大学共随机招募了 516 名和 1213 名预科生，分别使用 9 项社交媒体量表和 12 项一般健康问卷（仅在第二次调查中）进行评估。
第一次和第二次调查中分别有 46.3%和 56.3%的受访者符合社交媒体障碍标准。项目在潜在因素（成瘾）上的因子负荷适中。该模型在两个样本中都有相当不错的拟合度。平均的组内相关测量值是可接受的（0.612）。内部一致性（Cronbach's alpha）良好（样本 1 为 0.713，样本 2 为 0.724）。113 名受访者的重测信度良好（r=0.696，p<0.001）。各项目的项目-总分相关性均显著。每个项目的灵敏度范围从 67.7%（宽容）到 91.3%（逃避）；每个项目的特异性范围从 41.2%（逃避）到 87.6%（置换）。对于标准效度，社交媒体障碍量表总分与评估自尊、抑郁和情绪的一般健康问卷项目以及总分相关。
9 项社交媒体障碍量表可用于筛查尼日利亚预科生的社交媒体障碍。社交媒体障碍的高患病率应引起辅导员、教师和心理健康从业者的关注。尼日利亚需要制定关于社交媒体使用的公共卫生教育策略。
