Abstract

Bullying behaviour has remained a global issue with far-reaching consequences on their psychological well-being, social relationships, and academic performance among victims. Studies linking personality traits and self-esteem on bullying behavior within specific cultural contexts are lacking. Therefore, this study examined the predictive ability of personality traits and self-esteem on bullying behaviour among in-school adolescents in Ibadan North Local Government Area. Cross sectional survey design was adopted while purposive sampling technique was used to select the study location. Data were collected from 387 participants using validated scales and analyzed using multiple regression analysis and independent samples t-test to test two hypotheses that were accepted at p < 0.01 level of significance. The result demonstrated that personality traits and self-esteem jointly predicted bullying behavior among study participants [R² = .082, F(6, 380) = 5.66, p < .01]. In addition, the results revealed that agreeableness (β = .24, t = 4.58, p < .01) and conscientiousness (β = -0.12, t = -2.37, p < .01) independently predicted bullying behavior among study participants. However, self-esteem, extraversion, openness to experience and neuroticism did not independently predict bullying behavior among study participants. The novelty of the study is that it is the first time bullying behaviour is studied in a specific cultural milieu in Ibadan. It is recommended that a comprehensive, personality-focused anti-bullying programs be designed and implemented to reflect the cultural and educational contexts among in-school adolescents.

Abstract

Parenting is a multifaceted journey filled with joys, challenges, and responsibilities that significantly affect the well-being of both parents and children. Studies that investigated parenting styles have used different predictors with results giving varied results. This study examines the predictability of perceived parental stress and emotional intelligence on parenting styles among married couples in Ibadan, Nigeria. Cross-sectional survey design was adopted while purposive sampling technique was used to select the study population. Data were collected from 393 participants using validated questionnaires and analyzed using t-test of independent samples and multiple regressions. Two hypotheses were tested and accepted at p <.05 level of significance. The results revealed that perceived parental stress and emotional intelligence jointly predicted parenting styles [R2=.06, F(5,392)= 4.58, p <.05]. In addition, the result indicated that regulation of emotional appraisal (β = 15, t = 2.45, p <.05) and use of emotion (β =.15, t = 2.58, p <.05) dimensions of emotional intelligence independently predicted parenting styles. Finally, gender significantly influenced parenting styles [t(391)= 2.11, p <.05] such that male participants reported higher perceived parenting styles (M= 91.37, SD = 22.49) compared to their female counterparts (M = 87.22, SD= 16.29). The study concluded that perceived parental stress and emotional intelligence are strong predictors of parenting styles among study participants. It is recommended that stress management programs should be put in place to help parents reduce stress levels to improve their ability to provide better parenting care to their children.

Abstract

This study examines the influence of depression and hopelessness on suicidal ideation among undergraduates of the University of Ibadan, Nigeria. The study adopted cross-sectional survey design while purposive sampling technique was used to select the study population. Data were conveniently collected from 200 participants using validated questionnaires and analyzed using zero-order correlation and independent sample t-test statistics and accepted at p <.001 level of significance. The result revealed that depression (r=-.23, p <.00) and hopelessness (r=-.32, p <.001) negatively correlated with suicidal ideation among study participants. Furthermore, both depression [t (197) =-3.65, p < .001] and hopelessness [t(197) = -4.85, p <0.001] significantly contributed to suicidal ideation among study participants. However, there was no gender difference in suicidal ideation among study participants. The study concludes that depression and hopelessness strongly correlated with suicidal ideation among undergraduates of the University of Ibadan. The study recommends that the university authority should have a functional mental health clinic to attend to students diagnosed with suicidal thoughts and other psychological dysfunctions.

Abstract

Efficient transportation management plays a vital role in minimizing operational costs in the tobacco manufacturing industry. This study presents the application of Integer Programming using Excel Solver to optimize distribution logistics and reduce transportation expenses in a cigarette factory. The research employs a quantitative descriptive approach using simulated data representing production capacities and regional demand. A linear programming model is constructed to minimize total transportation costs while considering constraints such as factory capacity, regional demand, and non-negativity of shipment volumes. Excel Solver, as an accessible and widely adopted optimization tool, is utilized to determine the optimal allocation of product deliveries from factories to various distribution zones. The results indicate that Solver provides a cost-effective and practical solution for identifying optimal transport routes, reducing overall distribution costs, and improving operational efficiency. Furthermore, sensitivity analysis reveals the robustness of the model in responding to changes in cost parameters and capacity constraints. The study highlights the strategic potential of spreadsheet-based decision support systems in enhancing supply chain efficiency within the tobacco industry and similar manufacturing sectors..

Abstract

Quality of work-life has continued to dominate research as it is known to affect workers’ performance and organizational productivity. Studies have investigated different predictors of quality of work-life with different results. This study examines organizational climate, organizational safety and workplace stress as predictors of quality of work-life among workers in multinational companies in Rivers State, Nigeria. Cross-sectional survey design was adopted while purposive sampling technique was used to select two multinational companies in the study area. Data were collected from 207 participants using validated questionnaires. Data were analyzed using multiple regressions and independent samples t-test to test two hypotheses which were accepted at p <.001 level of significance. The result indicated that organizational climate, organizational safety and workplace stress jointly predicted quality of work-life among study participants R2 =.398, F( 3, 204) = 124. 461, p < .001. Furthermore, the results revealed that organizational climate (β = .105, p <.001), organizational safety (β= .164, p <.001) and workplace stress (β = -.129, p <.001) independently predicted quality of work-life among study participants. Finally, gender significantly influences quality of work [t(107) = 44.48, p <.001] such that female workers reported higher quality of work-life compared to their male counterparts. The study concludes that organizational climate, organizational safety and workplace stress served as excellent predictors of quality of work-life among study participants. The study recommends that multinational companies should develop positive organizational culture and workplace safety with minimal workplace stress which would improve overall quality of work-life among workers.

Abstract

The prevalence of polycystic ovary syndrome (PCOS) has significant implications on women's health-related quality of life (HRQoL). While the physical aspects of PCOS on HRQoL have been widely studied, studies linking psychological predictors of HRQoL among women with PCOS in Rivers State have received little investigation. Therefore, this study examines the predictive ability of psychological distress, anxiety, depression and stress on HRQoL among women diagnosed with PCOS in Rivers State, Nigeria. The study adopted cross-sectional survey design while purposive sampling technique was used to select the study population. Data were conveniently collected from 206 participants using validated scales and analyzed using multiple regression analysis to test five hypotheses which were accepted at p <.001 of significance. The results show that psychological distress, anxiety, depression and stress jointly predicted HRQoL among women diagnosed with PCOS (R2 = .777, F(4, 202) = 174.780, p<.001). Furthermore, psychological distress, R2= .748, F(1,204) = 605.644, p <.001; depression, R2 = .461, F(1,204) =174.289, p <.001; anxiety, R2 = .507, F(1,204) = 210.133, p <.001, and stress, R2 = .551, F(1,204) = 250.086, p<.001 independently predicted HRQoL among study participants. The study comes as the first among this population and sample. The study recommends government agencies, healthcare providers and other stakeholders to combine gynecological, psychological and lifestyle management strategies to support women diagnosed with PCOS in order to improve their HRQoL.

Abstract

Attachment styles are the foundation on which adult emotional health and interpersonal relationships are built. Studies linking childhood trauma and social support on attachment styles among young adults in Nigeria are lacking. Therefore, this study examines the predictive roles of childhood trauma and social support on attachment styles among young adults in Port Harcourt metropolis. Cross-sectional survey design was utilized while simple random sampling technique was used to select five communities in Port Harcourt metropolis. Data were collected from 278 participants using validated questionnaires and analyzed with multiple regression analysis to test one hypothesis accepted at p =.001 level of significance. The result indicates that childhood trauma and social support jointly predicted attachment styles among study participants, R2 = .274, F(2,275) = 27.50, p = 001. Furthermore, the results reveal that childhood trauma (β = .312, t = 3.59, p =.001) and social support (β = .281, t = 3.30, p =.001) independently predicted attachment styles among study participants. The study concludes that childhood trauma and social support are strong predictors of attachment styles among young adults in Port Harcourt metropolis. The study recommends that primary caregivers should provide a conducive social support system for young adults who have been traumatized to improve their adult relationship.

Abstract

Childhood trauma and social support are two critical constructs that significantly shape adult emotional health and interpersonal relationships. While studies have used different predictors to examine relationship satisfaction among different populations and samples, one group that has been understudy especially in the Nigerian setting is the young adults. Therefore, this study examines the predictive roles of childhood trauma and social support on relationship satisfaction among young adults in Port Harcourt, Rivers State, Nigeria. The study adopted cross-sectional survey design while purposive sampling technique was used to select youth samples from five communities. Data were conveniently collected from 278 participants using validated questionnaires and analyzed using multiple regression to test one hypothesis which was accepted at p = .001 level of significance. The result revealed that childhood trauma and social support jointly predicted relationship satisfaction among study participants, R2 = .248, F (2,275) = 31.56, p=.001. Furthermore, the result indicated childhood trauma (β = .243, t = 2.74, p = .007) and social support (β = .328, t = 3.73, p =.001) independently predicted relationship satisfaction among study participants. The study concludes that childhood trauma and social support are robust predictors of relationship satisfaction among young adults in the Port Harcourt metropolis. The study recommends that parents should foster nurturing and supportive environments and actively build and maintain strong social support networks that would help them cope with challenges and enhance their relationship satisfaction.
