Policing requires the mastering of emotions and the application of psychological principles such as emotional intelligence in dealing with members of the public. However, the corporate image of the police has not been good worldwide and there is increasing need for research in this area. Studies on emotional intelligence among police officers are scarce and are needed to understand the problems confronting this important sector of society. Therefore, this study investigated the psychosocial determinants of emotional intelligence among police officers in Ibadan, Nigeria. A survey research design was employed, and data were collected through a standardized questionnaire, the Eysenck Personality Scale and the Emotional Intelligence Scale. Two hundred and fifty-eight police officers from four different police stations in the Ibadan metropolitan area were accessed through a purposive sampling technique. The results revealed that educational qualifications did not significantly influence the emotional intelligence of police officers (F(8, 251) = .21, p > .05). There was a significant gender difference in emotional intelligence (t(256) = 2.17, p < .05), with males scoring significantly higher (X = 79.38, SD = 11.33) than their female counterparts (X = 75.43, SD = 15.26). It was also found that there was no significant difference in emotional intelligence between older and younger police officers (t(256) = .34, p > .05). Furthermore, the personality attributes extraversion, neuroticism and psychoticism did not significantly predict emotional intelligence jointly (F(3, 256) = 1.65; p > .05), and only neuroticism significantly predicted emotional intelligence independently (β = –.15, p < .05). Finally, there was no significant influence of the interaction of gender and the personality attribute of extraversion–introversion on emotional intelligence among Nigerian police officers in Ibadan. The study concluded that gender and the personality dimension of neuroticism are determinants of emotional intelligence and we recommend an emotional intelligence training programme for the Nigeria police.
Background and Purpose Poststroke depression (PSD) is a common complication after stroke. There is no adequate treatment for PSD. This study examined efficacy of cognitive rehabilitation therapy (CRT) in the treatment of PSD among stroke survivors. Methods An experimental design, 30 participants with poststroke depression were randomly assigned into 3 groups of cognitive rehabilitation therapy (CRT), psychoeducation (PE), and the control group (CG). CRT consisted of nine sessions with three-phased sessions focusing on activity stimulation, negative thoughts, and people contacts, PE consisted of nine sessions focusing on knowledge on stroke and poststroke depression, and the CG group was on the waiting list. The BDI scale was used for assessing PSD at posttest. Results There was a significant difference in the efficacy of CRT, PE, and the CG on PSD, with CRT–CG mean difference of −9.4 ± 3.11 and PE–CG 1.0 ± 3.83. Furthermore, stress was not a confounding variable on the efficacy of CRT. The type of therapy significantly influenced PSD at posttest, with the CRT having greater mean reduction to CG (−11.1 ± 3.1) than PE to the CG (3.0 ± 3.8). Conclusions Cognitive rehabilitation therapy significantly reduced poststroke depression. Hence, it should be integrated as an adjunct treatment of poststroke depression.
Background: In the continuous search for accessible, reliable and sensitive biomarkers for early detection of environmental lead exposure, authors determined the interaction between blood lead level (BLL), the conventional marker of lead exposure, and the indices of calcium and bone metabolism in children.Methods: This cross-sectional study involved 309 apparently healthy children from eight public primary schools in Ibadan, Nigeria who were classified as Elevated BLL (EBLL) and control based on standard cut-off for childhood BLL. BLL, serum Ca (tCa), phosphate, magnesium (Mg), 25-hydroxy-Vitamin D, alkaline phosphatase (ALP), urinary calcium (uCa) and urinary deoxypyridinoline (uDPD) were determined using AAS, HPLC and ELISA as appropriate. Bone-specific ALP (B-ALP) and ionized calcium (iCa) were calculated using standard formulae. Data analyses involved Student’s t-test, Pearson correlation and multivariate regression analysis. p<0.05 was considered statistically significant.Results: BLL and 25-OH-Vitamin D levels were increased in EBLL (0.4±0.1 µmol/L and 60.1±10.7 mmol/L) compared with control (0.2±0.0 µmol/L and 55.1±14.3 mmol/L) p <0.05. No significant differences existed in the levels of ALP, B-ALP, uCa, uDPD, tCa, iCa, phosphate and Mg in both groups (p>0.05). BLL had significant positive correlation with uCa (r=0.176, p=0.002) (p<0.05) but no significant correlation with uDPD, ALP, B-ALP, tCa, iCa, phosphate, Mg and 25-OH-Vitamin D (p>0.05). BLL could be accounted for by uCa by applying the equation, BLL=0.329+0.324uCa.Conclusions: Urinary calcium could be a promising predictive biomarker for early recognition of significant environmental lead exposure in children.
Blood lead level (BLL) is insufficiently sensitive for early detection of Lead-induced neurotoxicity (LIN). This study determined the possible role of the combination of BLL, intelligent quotient (IQ) and erythrocyte acetylcholinesterase (AChE) activity in the early detection of LIN in Children. Apparently healthy children (n=309) from eight public primary schools in Ibadan, Nigeria were recruited and classified into: children with Elevated BLL (EBLL) and children with Acceptable BLL (control) based on CDC cut-off for childhood lead exposure. Neurological indices (speech, memory, cranial nerves and cerebellar functions), IQ, BLL and erythrocyte AChE activity were assessed using standard methods, Standard Progressive Matrices, AAS and HPLC respectively. Statistical analysis involved Student’s t-test, Pearson’s correlation and multivariate regression. p<0.05 was considered significant. There were 169 (54.7%) children with EBLL while there were 140 (45.3%) control children. Both groups exhibited normal speech, memory, cranial nerves and cerebellar functions. However, IQ was lower in EBLL children (85.9±11.6) compared with control (91.5±14.0) while BLL and AChE activity were higher in EBLL children (0.4±0.1 µmol/l; 117.5±25.5 µkat/l) compared with control (0.2±0.0 µmol/l; 59.4±10.2 µkat/l). BLL showed inverse correlation with IQ (r=–0.134, p=0.019) but positive correlation with AChE (r=0.978, p≤0.001). 16.2% of the observed variation in BLL could be accounted for by AChE using the equation; [BLL=–0.007+0.003 AChE] p<0.05. Elevated blood lead level is prevalent among the school children and appears to have adverse effect on their IQ. Erythrocyte AChE could be a promising marker for early recognition of significant environmental lead exposure and lead-induced neurotoxicity in children.
IntroductionEpilepsy has long been associated with cognitive dysfunction and educational underachievement. The purpose of the study was to describe the baseline findings from a larger prospective study.MethodsNew cases of epilepsy aged 6-16 years seen at a paediatric neurology clinic in Ibadan, Nigeria were evaluated for any evidence of cognitive impairment. Intelligence quotient (IQ) of the participants was measured using the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Scores on cognitive subtests and Full Scale IQ (FSIQ) were computed and association between the subsets scores and seizure variables were calculated.Results40 children, 24 males and 16 females were studied and their ages ranged from 6 to 16 years with a mean of 10.8 (SD=3.0) years. Global intellectual functioning as measured by the WISC-IV was in the normal range (FSIQ scores <85) for 52.5% (n = 21) of the participants and the remaining participants (47.5%) scored between the borderline and severe category for intellectual disability. The strongest correlation was between ‘caregiver's assessment of school performance’ and FSIQ, (r = 0.70; p< 0.001). Age at onset of epilepsy and seizure type had no significant association with scores on the WISC-IV composite scores.ConclusionThere is a high prevalence of significant cognitive dysfunction in Nigerian children with epilepsy, even in the absence of any known brain insult. All children with epilepsy should have routine IQ assessment following diagnosis, in order to allow for early intervention when indicated, and thus, improved outcomes.
Background: To prevent completed suicide among young adults in the university, assessment of suicidal ideation should be encouraged. This study aims to investigate the reliability, exploratory factor analysis, and validity of adult suicidal ideation questionnaire among Nigerian university students. Methods: Descriptive cross-sectional survey was the preferred choice of research design for this study utilizing convenience sampling technique to recruit participants. 6 universities divided into two equal numbers between federal-funded and state-funded ones in Nigeria were selected, and 2,702 students were sampled to fill the questionnaires. Instruments for data collection included Rosenberg Self-esteem questionnaire and Kessler Psychological distress scale to validate ASIQ. Ethical clearance for this study was collected from Olabisi Onabanjo University Teaching Hospital, Nigeria. Results: The results of the study showed that internal consistency of ASIQ was .951 while validity analyses proved that self-esteem and psychological distress diverged and converged respectively with the three subdomains of suicidal ideation as measured by ASIQ. Conclusion: This study concludes that ASIQ has slight modification from the original version among young adults in Nigeria. The scale is reliable and valid but as a 22-item instrument on a 5-point Likert scale.\ Keywords: Adult suicidal ideation questionnaire; psychometric properties; Nigerian University students.
