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.

Background: Health care workers (HCWs) are the frontline of coping COVID-19 pandemic, which indicates the importance of improving their mental wellness to better cope with the situation. Objectives: The current study aimed to firstly assess the severity of anxiety and depression and perceived vulnerability to diseases, and secondly to investigate their association with the fear of COVID-19 among Nigerian HCWs. Methods: For this cross-sectional study, a purposefully selected sample of 413 HCWs from two tertiary healthcare institutions in Benin City, Edo State, South-South Nigeria, responded to the Fear of COVID-19 Scale, Hospital Anxiety and Depression Scale, and Perceived Vulnerability to Disease Scale. Data was collected between October 2020 and February 2021. Descriptive statistics were used to summarize socio-demographic variables, while inferential statistics (t-test for independent samples, one-way ANOVA, and linear regression) were used to test hypotheses. Results: A high prevalence of anxiety, depression, and perceived vulnerability to diseases (PVD) was observed. Perceived infectability (β = 0.244, P = 0.000), germ aversion (β = 0.166, P = 0.000), and composite PVD (β = 0.96, P = 0.000) were identified as independent and significant predictors of fear of COVID-19, accounting for 7.5; 3.3, and 9.9% variance in the severities of Fear of COVID-19, respectively. Anxiety and depression showed a significant joint prediction of Fear of COVID-19 severity, accounting for a 4.0% variance in the severity. Fear of COVID-19 was not found to be influenced by sex or job type differences among the HCWs. Conclusions: This study demonstrated a high incidence of anxiety, depression, and perceived vulnerability to COVID-19 among Nigerian HCWs. These reported symptoms of psychopathology are also strong independent and joint predictors of fear of COVID-19.

Aim: This study examined Internet Addiction (IA) and Problematic Smartphone Use (PSU) as predictors of severities of anxiety, depression and psychological distress among university undergraduates in Nigeria. Study Design: Exploratory /Descriptive survey design. Place and Duration of Study: Redeemer’s University Nigeria, between April and August 2018. Methodology: A total of 854 university undergraduates made up of 342 males and 512 females, mean age 20.5 years, were purposively selected from four universities in Osun state, southwestern Nigeria. Internet Addiction Test (IAT), Smartphone Addiction Scale – Short Version (SAS-SV), Beck Anxiety Inventory (BAI), Centre for Epidemiological Studies Depression Scale (CES-D) and General Health Questionnaire (GHQ-12) were used for data collection.  Results: Observed prevalence of studied variables among respondents are: Internet Addiction (IA) 48.6%, Problematic Smartphone Use (PSU) (47.4%), anxiety disorder (50.6%), depression (49.8%) and psychological distress (47.6%). IA independently and significantly predicted severities of anxiety disorder (R² = .01, p = .025), depression (R² = .057, p = .000) and psychological distress (R² = .105, p = .000). PSU independently and significantly predicted severities of depression (R² = .073, p = .000) and psychological distress (R² = .094, p = .000). However PSU failed to significantly predict severity of anxiety disorder (R² = .00, p = .650) among the participants. Conclusion: High prevalence of IA, PSU, anxiety disorder, depression and psychological distress exist among the participants. IA is a significant independent predictor of anxiety, depression and psychological distress. PSU is a significant independent predictor of depression and psychological distress but is not a significant predictor anxiety disorder among Nigerian undergraduates.

Aims: There is dearth of information on the psychometric of measures of personality on Nigerian population. This study investigates the internal consistencies and validity scores on the Mini- International Personality Item Pool (mini-IPIP) on Nigerian respondents. Study Design: A cross-sectional survey design was used to validate the scale. Place of Study: University of Ibadan, Oyo State, South-western Nigeria. Between January and April 2022. Methodology: A multistage sampling technique was used to select two hundred and nineteen (219) individuals, made up of 113 (51.6%) of males and 106 (48.4%) of females, between the age of 35 and 61 years with Mean age = 46.49 ± SD = 6.23. The participants included administrative, technical and junior staff working in the University of Ibadan, Oyo State, and South-western Nigeria. Participants responded to The Big Five Inventory (BFI-10) and Mini-IPIP. The internal consistencies for the Mini-IPIP was calculated and obtained using Cronbach’s (α) reliability coefficient. Also, the concurrent validity coefficient was obtained using Pearson's Correlation Analysis, Min-IPIP was correlated with BFI-10 in order to ascertain the concurrent validity. The items total correlations were also obtained to test the relationship between each item and the composite/total item score. Results: A modest but acceptable internal consistency of Extraversion, α =.80; Agreeableness, α =.79, Conscientiousness, α =.84; Neuroticism, α = .83; and Openness to Experience α =.88 for the factors of mini-IPIP was revealed. Positive concurrent validity coefficient was equally observed between the subsections of Mini-IPIP and the BFI-10 (r = .34, .12, .18, .20, .11 for extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience subscales respectively). Conclusion: These findings provide evidence for the use of Mini-IPIP scale as screening tool for the assessment of human personality in Nigeria based on the five-factor model.
