Background: Research studies show a high penetration rate of Facebook usage among Nigerian most of which are compulsive. The Bergen Facebook Addiction Scale (BFAS) had been validated in many languages and is used in many countries but not yet in Nigeria. This study validates BFAS to determine psychometric properties acceptable for Nigerian population.Method: A total of 864 (mean age 20.5) undergraduates purposively selected from two stateowned and two privately owned Universities in Osun state southwestern Nigeria made up of 352 male and 512 females, participated in the study. Participants responded to Bergen Facebook Addiction Scale (BFAS), Internet Addiction Test (IAT), and Smartphone Addiction Scale-Short Version (SAS-SV).Section 6. Psychology 32Results: Determined new norm for the six factors of BFAS for both male and female ranged from ≥ 42.3 (relapse) to ≥ 50.5 (mood modification). Internal consistency showed a Cronbach's coefficient of .90, a Spearman-Brown coefficient of .83 and Guttman Split-Half coefficient of .83. All items in the scale reported acceptable goodness-of-fit measures revealing corrected item-total correlations range of .88 to .90. All the factors of BFAS had acceptable Cronbach standardized alpha ranging from salience .73, to mood modification .81. Significant positive correlation was observed between the scales revealing concurrent validity scores of r = .558, p= .000 between BFAS and SAS-SV and r = .508, p = .000 between BFAS and IAT.Conclusion: BFAS is none gender sensitive and has acceptable psychometric properties for Nigerian population.

Background: In 2018, the Nigerian Communication Commission affirmed that more than 100 million Nigerians made use of the Internet. A good percentage of internet usage is maladaptive. A valid, reliable, and socio-culturally sensitive assessment instrument is essential to study internet usage patterns in Nigeria. Young’s Internet Addiction test (IAT) has been validated in many countries, but not in Nigeria. Objectives: This study aimed to validate IAT to determine psychometric properties acceptable in a Nigerian population. Materials and Methods: A total of 184 Nigerian University undergraduates (77 males and 107 females), mean age = 20.5, were purposively drawn, and they responded to IAT, the Smartphone Addiction Scale-Short Version (SAS-SV), and the Bergen Facebook Addiction Scale (BFAS). Results: The Cronbach’s α of the six IAT factors ranged from 0.25 (anticipation) to 0.69 (salience). The observed overall Cronbach’s α coefficient of 0.79 was obtained for IAT. The corrected item-total correlations ranged from 0.73 to 0.84. The concurrent validity score was observed to be r = 0.54 between IAT and SAS-SV and r = 0.58 between IAT and BFAS. A significant positive correlation was equally observed between the IAT and BFAS factors, ranging from conflict (r = 0.322, P = 0.000) to relapse (r = 0.488, P = 0.000). The new norm determined for IAT in the Nigerian population was ≥ 38.5 for males and ≥ 40.8 for females. Conclusions: IAT is gender-sensitive and has acceptable psychometric properties for the Nigerian population.

This study was carried out to observe the link between parental factors and Conduct Disorder (CD) among Nigerian school adolescents. A cross-sectional survey research design was adopted for the study where multi-stage sampling techniques led to selecting 1006 participants (mean age = 15.4 years) from six secondary schools in Ibadan, Oyo State, Southwestern Nigeria. Participants responded to Socioeconomic Status (SES) scale, the Parenting Styles Scale (PSS) and Frequency of Delinquent Behaviour Scaling Instrument (FDBSI). A high prevalence of CD was observed. We also observed that parenting styles significantly influenced conduct disorders. Responsive parenting is not a significant predictor of CD, while control parenting significantly predicted CD. Parental occupation significantly influenced CD, with formal occupation types having higher mean scores for both fathers and mothers. Finally, there was a significant influence of socioeconomic status on conduct disorder among the participants. Findings concluded that there is a high prevalence of conduct disorder. Authoritarian and uninvolved parents with formal occupation and families with higher socioeconomic status were conduct disorder determinants among adolescents.

The physical and psychological health challenges of Self-Medication (SM) for a pregnant woman and the unborn child spotlights it as an emergency. This unwraps a gap in epidemiological studies on SM and associated psychopathological symptoms among Nigerian pregnant women. This study examines the predictive influence of self-medication with Over The Counter (OTC) drugs on manifested psychopathological symptoms among pregnant women attending antenatal clinic in State Specialist Hospital, Osogbo, Osun State, southwestern Nigeria. Purposively selected 277 pregnant women ( x age = 29.33; SD = 4.77) participated in the study. The participants responded to the Substance Abuse Prevalence Inventory, Self-Medication Test (SMT), and Awaritefe Psychological Index (API). Findings reveal a low prevalence of psychoactive drug use (2.8%) and a high prevalence of (OTC) drug self-medication (31.4%) and psychopathological symptoms (34.7%). Self-medication with OTC drugs independently and significantly predicted severities of insomnia (β = .178, p = .001), intellect disorder (β = .244, p = .000), heat disorder (β = .109, p = .046), mood disorder (β = .188, p = .001), head region disorder (β = .162, p = .003), alimentary tract disorder (β = .118, p = .030), general somatic disorder (β = .244, p = .000), and general psychopathology (β = .229, p = .000). The study reports a high prevalence of psychopathological symptoms among the Nigerian sample and concludes that the SM of OTC drugs is a significant predictor of the severity of the symptoms of psychopathology among pregnant women.
