Psychometric Properties and Validation of the 9-Item Social Media Scale Among Pre-University Students in Nigeria.

OBJECTIVE: To validate the Social Media Disorder scale in Nigerian adolescents by determining its unidimensional structure, reliability, sensitivity, specificity, and criterion validity. METHODS: 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). RESULTS: 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. CONCLUSION: 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.

Quality of sleep and psychological distress in glaucoma

Background: People living with glaucoma are psychologically burdened because of the threat of visual loss. Therefore, understanding the psychosocial issues and quality of sleep holds important implications for the recognition, prevention, and treatment of emotional problems among people with glaucoma. This study investigated the quality of sleep and psychological distress among people with glaucoma.Methods: This was a cross-sectional study of adults recruited over a period of 12 weeks from a glaucoma clinic of a Teaching Hospital in south-west Nigeria. The quality of sleep and psychological distress were evaluated using the Pittsburgh Sleep Quality Index and General Health Questionnaire respectively.Results: Ninety-three adults with glaucoma participated in the study. The mean age was 62.33 ± 15.25 years. Fifty-seven (61.3%) of the subjects were poor sleepers while 27 (29.0%) were psychologically distressed. Psychological distress correlated with global sleep score (r = 0.399, p = 0.000), subjective sleep quality (r = 0.341, p = 0.001), sleep latency (r = 0.245, p = 0.018) and sleep disturbance (r = 0.279, p = 0.007).Conclusion: Psychological distress and sleep disturbances were common among patients with glaucoma. Concerns about these issues should be incorporated into routine clinical evaluations of patients with glaucoma
