- ItemDevelopment and Validation of Redeemer’s University Romantic Jealousy Scale (RUN-RJS)(North American of Psychology, 2022) Ogunsemi, Joshua O.There is a paucity of indigenous assessment tools to measure severities of romantic jealousy among the Nigerian population despite its high prevalence reported in the literature. The development and validation of a romantic jealousy scale titled Redeemer's University Romantic Jealousy Scale (RUN-RJS) was thus initiated. A principal component analysis extracted 6 components from items whose eigenvalues exceeded 1. Eleven items loaded best in the first component; 9 items loaded in the second component while 12 items loaded in the third component. The scree plot analysis retained three components (romantic jealousy symptoms). The RUN-RJS has a Cronbach's alpha of .89, .89, .86 for the three dimensions of cognitive, emotional and behavioural subscales. Measures of convergent validity and discriminant validity showed that the RUN-RJS is gender-sensitive, has robust psychometric properties and is recommended as a diagnostic tool for romantic jealousy among adults in Nigeria.
- ItemDevelopment and Validation of the Redeemer’s University Adverse Childhood Experiences Scale(North American Journal of Psychology, 2024) Ogunsemi, Joshua O.Assessing adverse experiences is essential when considering their long-term effects on individuals and the health of communities. This study aimed to develop and validate the Redeemer’s University Adverse Childhood Experience Scale (RUACES) among Nigerian adolescents. A cross-sectional study was conducted in Lagos State, Southwest Nigeria; 316 participants (147 males and 169 females) were selected among in-school adolescents from Lagos State between the ages of 11–19 years (Mean = 15.5; SD=1.66). An initial 45 items were generated through FGD and a thorough literature search. An exploratory factor analysis (EFA) using principal component analysis was used to extract 14 components. Of the 45 items, 18 loaded optimally on the first factor, 3 on the second, and 2 on the fourth and eighth factors. Items in the first and second components were retained, while others were removed due to their complex structure and insufficiency. Cronbach's alpha for the RUACES was found to be .87. Concurrent validity coefficients between RUACES and Benevolence Childhood Experiences and between RUACES and Childhood Trauma Questionnaire were found to be r = -.325 (p < 0.001) and r = .367 (p < 0.001), respectively. Based on these results, the Redeemer’s University Adverse Childhood Experience Scale exhibits adequate psychometric qualities. The scale can be used in an educational centre and child and adolescent clinic to assess adolescents who experienced adversity during childhood and are currently experiencing adversity.
- ItemInfluence of Peer Pressure, Loneliness and Self-esteem on Pre-marital Sexual Activities among Undergraduates in Redeemer's University, Osun State, Nigeria(Asian Journal of Education and Social Studies, 2025-06) Ogunsemi, Joshua O.Pre-marital sexual activities have been identified as pressing social and public issues among university students, with severe implications for contracting sexually transmitted diseases. The objective of this study was to examine the influence of psychological factors (loneliness, peer pressure and self-esteem) on pre-marital sexual activities among Redeemer's University undergraduates. Using a cross-sectional design, three hundred and eighty undergraduates - 194 males and 186 females between the ages of 16 and 25 years (M=18.99, SD=1.61) were purposively selected for the study. A self-reported questionnaire consisting of a demographic data form, University of California Loneliness Scale (UCALS), Yielding to Peer Pressure Scale (YPPS) , Rosenberg Self-Esteem Scale (RSES) and the Sexual Abstinence Behaviour Scale (SABS) was used to collect data. Descriptive statistics, multiple linear regression, and an independent sample t-test were utilised for the inferential data. The findings revealed a percentage variance of 5% for psychological components (loneliness, peer pressure and self-esteem) and 14% for sociodemographic variables on pre-marital sexual activities. Self-esteem [β = -.13, t = -2.57, p<.05], loneliness [β = .14, t = 2.79, p <.05], and peer pressure [β = .12, t = 2.33, p <.05] were significant predictors of pre-marital sexual activity. Significant gender differences were observed in pre-marital sexual activities among the participants (t (380) = -7.23, p <.01), surprisingly with females having higher tendencies to engage in pre-marital sexual activity compared to their male counterparts. It is recommended that mental health counsellors implement programmes to enhance the self-esteem and social skills of those identified as vulnerable in the undergraduate population.
- ItemPerceived Vulnerability to COVID-19 Infection and Psychosocial Well-Being of Nigerian Residents(International Journal of Innovative Research in Medical Science (IJIRMS), 2020) Ogunsemi, Joshua O.The outbreak of the novel (SARS-CoV-2), known as COVID-19, has sparked global severe physical and mental health concerns in many spheres. Part of the identified mental health factors affecting people's psychosocial well-being is an increased level of health worries due to the perception of vulnerability, which has been raised by excessive exposure to news, information on rising cases, mortality, and many others. This study focuses on the predictive influence of perceived vulnerability to COVID-19 infection among Nigerian residents during the COVID-19 outbreak. A total of 355 Nigerians, 175 (49.3%) males, 180 (50.7%) females aged between 18 years and 42 years (M = 27.24, SD =7.05) participated in the study through an online snowball method. Data was collected using the Perceived Vulnerability to Disease Questionnaire (PVDQ) and Mental Health Continuum Scale- Short Form (MHC-SF). Analysis of results reveals a high prevalence of low psychosocial well being. That perceived vulnerability to COVID-19 infection significantly predicts psychosocial wellbeing (F (1,353) = 71.8, adj. R2 =.165, p <.01) among respondents. No significant sex influence was observed on psychosocial well-being; educational qualifications and marital status were found to significantly influence the psychosocial well-being of Nigerians during the COVID-19 Pandemic. The authors conclude that perceived vulnerability to COVID-19 infection predicts the psychosocial well-being of Nigerian residents during the COVID-19 Pandemic outbreak.
- ItemPredictive Roles of Cognitive and Behavioural Emotion Regulation Strategies on Loneliness among Undergraduate Students at Redeemer's University, Nigeria(2024-06-01) Ogunsemi, Joshua O.Loneliness is a public health concern as it tends to be a risk factor for mental disorders. This study investigated the predictive impact of cognitive and behavioural emotion regulation on loneliness among undergraduate students at Redeemer's University Ede, Osun State. A Cross sectional research design was employed for the study. A convenient sampling technique was adopted in selecting a total of 321 participants (224 females and 97 males) (Mean age=18.30, SD=1.78). The sample responded to self-report measures of Cognitive Emotion Regulation Questionnaire (CERQ), Behavioural Emotion Regulation Questionnaire (BERQ) and 3-item Loneliness Scale. Three hypotheses were generated and tested using Multiple and Linear Regression analyses. Results showed that participants who felt lonely were characterised cognitively by greater use of rumination (β=.22, p < .01) and self-blame (β=.22, p < .01), and lesser use of other cognitive strategies. Behaviourally, loneliness was characterized by greater use of actively ignoring stressful situations (β= .16, p < .01). Gender and age did not predict loneliness. Still, gender has a significant relationship with withdrawal [r (319) = .12, p < .05] while age has with acceptance [r (319) = -.11, p < .05] and ignoring [r (319) = -.22, p < .01]. Based on the findings of this study, it is seen that individual differences in emotion regulation may play an important role in explaining loneliness and could therefore represent a promising treatment plan.
- ItemPSYCHOACTIVE SUBSTANCE DEPENDENCE AMONG NIGERIAN YOUNG PEOPLE: ADVOCACY FOR DECRIMINALIZATION POLICY(Journal of Behvaioural Studies, 2024) Ogunsemi, Joshua O.The prevalence of drug use among young people is on the increase in recent years despite the myriad cross-cutting tasks and preventive measures taken to stem this tide. Psychoactive Substance Dependence (PSD) suggests a helplessness in the user to stop the consumption of the drug despite its potential harm. Studies on PSD among Nigerian students is scarce hence the attempt of this study to bridge this gap. About 332 male and female students responded to the Substance Dependence Scale (SDS) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Descriptive and inferential statistics were used to analyse data. Reported prevalence of psychoactive substances use are 16.9% (alcohol), 7.2% (sedatives), 7.2% (hallucinogens), 3.0% (inhalants), 3.0% (amphetamines), 2.4% (cocaine), 2.0% (cannabis), 2.0% (opioid) and 1.2% (tobacco). The nature of PSD showed that 5.6% are not in control of their psychoactive substance use, 27.2% are anxious on missing doses, 9.4% are worried about their substance use. 22.8% wish they could stop the use of illicit drugs, while 5.0% find it difficult to abstain from drugs. In all, 21.7% and 7.2% of participants reported mild, moderate, and severe PSD, respectively. Significant gender influence was observed on PSD, with males reporting a higher mean score than female students. No significant mean score difference was found in PSD of secondary and tertiary education students. Judging that a considerable number of illicit drugs users are “hooked” to drugs and indirectly crying for help, this study advocates a drug decriminalization policy that treats as victims rather than criminalize users caught in possession illicit drugs particularly within Nigerian school premises
- ItemPsychometric Properties and Validation of Mini International Personality Item Pool (Mini-IPIP) among Nigerian Population(Advances in Research, 2022) Ogunsemi, Joshua O.Aims: There is a dearth of information on the psychometric properties of measures of personality in the 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%) males and 106 (48.4%) females, between the ages of 35 and 61 years, with a Mean age = 46.49 ± SD = 6.23. The participants included administrative, technical and junior staff working in the University of Ibadan, Oyo State, and Southwestern 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 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.
- ItemSatisfaction With Life Scale (SWLS): Confirmatory Factor Analysis and Psychometrics Properties Among Sample of Nigerian Middle-Aged Workers(Corpus Intellectual, 2024) Ogunsemi, Joshua O.Measuring the cognitive aspect of well-being is significant in today’s world due to its link with mental health. The current study examined the factorial structure, psychometric properties and concurrent validity of the Satisfaction with Life Scale (SWLS) within the Nigeria socio-cultural setting. At the initial phase of the study, 109 participants working in a government-owned University in Oyo State, Nigeria, completed the five-item SWLS and their information was analysed utilising confirmatory factor analysis. One hundred and ten participants from a privately-owned university in Osun State, Nigeria, were used to validate the instrument with a similar measure concurrently: the six-item Riverside Life Satisfaction Scale (RLSS) at the second phase. The SWLS possess a satisfactory reliability (Omega (ωt) = .84). The model fit indicators observed after exposing the SWLS to confirmatory factory analysis revealed moderately suitable fitness and acceptable item loading for a single factor scale. A statistically significant Pearson’s (r) of = 0.79, p<.01 was observed between SWLS and RLSS. The SWLS possess acceptable psychometric properties. It is valuable for investigating life satisfaction within Nigeria's sociocultural contexts.

- ItemSociodemographic Factors and Life Satisfaction as Predictors of Retirement Anxiety among Staff in Nigerian Universities(North American Journal of Psychologyh, 2023) Ogunsemi, Joshua O.Retirement anxiety is a major phenomenon among employees who have negative expectations about their future retirement; however, information on the impact of psychosocial factors on retirement anxiety is scarce. This study investigated the effect of demographic characteristics and life satisfaction on three factors of retirement anxiety among Nigerian university employees. Retirement anxiety was conceptualised in three dimensions, namely, personal obligation, financial planning, and social detachment concerns. Using a cross-sectional survey method, 306 non teaching staff were purposively selected from four universities in South west Nigeria. Participants completed the Redeemer’s University Retirement Anxiety Scale (RURAS), Satisfaction with Life Scale (SwLS) and a socio-demographic information form. Data were analysed using hierarchical multiple regression. High retirement anxiety in all the domains was observed among males, junior staff, older workers, those with fewer educational qualifications, and those with a large family size. A higher number of years on the job predicted personal obligation concerns, but did not predict financial planning and social detachment concerns. Job status predicted social detachment and financial planning concerns, but did not predict personal obligation. Lower life satisfaction was significantly associated with higher retirement anxiety across the three domains. Results showed that particular demographic and occupational attributes, and poor satisfaction with life, contributed to retirement anxiety. Psychological interventions and revision of retirement benefits laws are recommended to address retirement anxiety.
- ItemThe Moderating Effects of Social Support and Gender on the Relationship between Environmental Justice Perceptions, Environmental Engagement, and Well-Being among Residents of Ota(2024-12) Ogunsemi, Joshua O.Background: In urban areas where environmental challenges and socio-economic disparities are prevalent, such as Ota, Nigeria, the complex interplay between environmental justice perceptions, environmental engagement, and well-being presents significant challenges. These issues are exacerbated by inadequate social support systems and gender disparities, making it challenging to address environmental injustices effectively and improve the overall well-being of residents. Methods: This study employed a cross-sectional survey design, involving a total of 324 participants, aged 18 - 65 years (mean age = 43; SD = 16.79) that were recruited using a stratified random sampling technique. Data were collected using the Scales of Psychological Well-Being (SPWB); Environmental Justice Perception Scale (EJPS); Olabisi Onabanjo University Attitude Toward Environmental Engagement Scale (OOUATEES); and the multidimensional scale of perceived social support (MSPSS), descriptive and Pearson correlation matrix, and analysed using hierarchical regression models. Results: The findings indicated that better perceptions of environmental justice are associated with higher levels of general well-being [β = 0.25, t = 4.66, p < 0.00]. Engagement in pro-environmental behaviours was also positively linked to improved well-being [β = 0.16, t = 2.99, p < 0.00]. Environmental engagement significantly moderated the relationship between environmental justice perceptions and general well-being, amplifying the positive effects (β = 0.25, t = 4.66, p < 0.01). However, social support and gender did not significantly moderate these relationships, suggesting that the primary influences of environmental justice (β = 0.26, t = 4.83, p < 0.01) and environmental engagement (β = 0.19, t = 3.82, p < 0.01) are robust enough to overshadow the moderating roles of these variables. Conclusion: The study highlights the critical role of environmental justice perceptions and pro-environmental engagement in enhancing general well-being among residents of Ota. While social support and gender are important factors in well-being, their moderating effects may be less pronounced in environments with strong predictors like environmental justice and engagement. These findings underscore the need for targeted interventions that promote environmental fairness and active engagement in environmental activities to improve overall well-being.
- ItemVALIDATION OF THE GA MING ADDICTION SCALE (GAS) ON NIGERIAN ADOLESCENTS(International Journal of Recent Advances in Multidisciplinary Research, 2020-08) Ogunsemi, Joshua O.A cross-sectional survey design utilizing an ex-post factor design was adopted to validate the Gaming Addiction Scale (GAS) using Nigerian secondary school adolescents. A purposive sampling technique was used to select the 338 (mean age and SD13.60 ±1.867) participants made up of 149 males and 189 females from several randomly selected secondary schools in a Local Government Area of Edo State, Nigeria. Participants responded to Gaming Addiction Scale (GAS) and Internet Gaming Disorder Test(IGD-20).Observed internal consistency of GAS showed a Cronbach's alpha coefficient of .75, a Spearman-Brown coefficient of.71 and Guttman Split-Half coefficient of.71. All but one of the items in the scale reported acceptable goodness-of-fit measures revealing corrected item-total correlations range of .192 to .523.Significant positive correlation was also observed between GAS and IGD-20 revealing concurrent validity score of (r = .459, P= .000).Determined new norms for GAS were scores51.81 for male and 47.98for female. GAS is gender sensitive and has acceptable psychometricproperties for Nigerian population.
