Validation of the Sleep Quality Questionnaire among senior students in Benin City, Nigeria.

Background: The Sleep Quality Questionnaire (SQQ) is a short and easy-to-understand resourceful tool for measuring poor sleep quality; however, it remains to be validated. Aim: The focus of this study is to determine its reliability and validity among Nigerian adolescents. Setting: Four gender-mixed schools within Benin City, Nigeria were selected to participate in the study. Methods: Questionnaires containing the SQQ, the Sleep Condition Indicator (SCI), which is a validated scale, and the Hospital Anxiety and Depression Scale (HADS) from 377 students selected from the junior and senior secondary school students were analysed. Results: The mean age calculated was 14.78 years for 174 male and 203 female students. Cronbach's alpha for the SQQ scale was 0.70. It correlated strongly with the SCI (rho = 0.93, p = 0.00), weakly with the HADS depression (rho = -0.19, p < 0.01) and anxiety (rho = -0.30, p < 0.01), but had no association with gender. Factor analysis revealed three factors with an eigenvalue greater than 1. Factors 1-3 accounted for 31.78%, 15.16% and 11.26% of the variance, respectively, totalling 58.2%. The reliability of each of the three factors was as follows: factor 1, 0.75; factor 2, 0.47; and factor 3, 0.62. The SQQ demonstrated good specificity and sensitivity at a cut-off point of 18. Conclusion: It is therefore recommended that the SQQ be included in the screening of sleep-related problems in adolescents, both in the primary and secondary care settings in Nigeria. Contribution: The research shows that the Sleep Quality Questionnaire is both a reliable and valid screening tool among adolescents in Nigeria. Its brevity and simplicity further promote its use in clinical and non-clinical settings.

Gender and other risk factors associated with risky behaviours among Nigerian adolescents.

Risky behaviours in adolescents, apart from substance use, and their associate factors, have not been thoroughly investigated in Nigeria. Hence, there is a need to study the prevalence of risky behaviours and their relationship with gender and other potential risk factors. Data comprising socio-demographic, risky behaviours, personality traits, religious orientation and substance use were obtained from 300 randomly selected secondary school students. Two risk groups (low and high) based on the number of risky behaviours were determined. Male was a risk factor for theft (OR = 2.1; 95%CI = 1.17-3.95), bullying (OR = 2.76; 95%CI = 1.37-5.56) and fighting (OR = 2.14; 95%CI = 1.35-3.40). Fifty-two (17.3%) of the students were of high-risk behaviour group. Furthermore, private school (ß = 1.05; P = 0.010), poor perceived relationship with teachers (ß = 1.21; P = 0.002), polygamy (ß = 1.20; P = 0.002) and lifetime cigarette use (ß = 1.07; P = 0.027) were predictors of high-risk behaviour group. Substantial proportion of adolescents in Nigeria exhibit risky behaviours of which gender and other factors play a significant role.

Prevalence and correlates of depression and anxiety disorder in a sample of inmates in a Nigerian prison.

BACKGROUND TO THE STUDY: Prisoners tend to be marginalized and deprived of the rights and privileges that other citizens in the community enjoy. Their separation from families, adverse effects on health of prison environment, and the uncertainty about the future place a great psychological burden on them which can lead to the development of mental illness. AIMS AND OBJECTIVES: The aim of this study was to determine the prevalence of psychiatric morbidity (depression and anxiety) and the associated factors among a sample of the prison inmates. MATERIALS AND METHOD: The study was descriptive and cross-sectional in design; it was conducted in a medium security prison in Benin City, Nigeria. Participants were interviewed with the Self-Reporting Questionnaire-20, the Hospital Anxiety and Depression Scale, and a socio-demographic questionnaire. Two hundred and fifty-two prisoners who were selected by systematic sampling techniques participated in the study and the data were analyzed using the 16th version of the SPSS with the statistical level of significance set at p < 0.05. Data were presented in tables; frequencies and percentages were calculated. Chi-square and logistic regression statistical tests were performed to determine variables that have relationship with psychiatric morbidity. RESULTS: The mean age of the respondents was 33.6 years (SD ± 9.29), and the majority of the respondents (43.7%) were in the age range 21-30 years. The prevalence of general psychiatric morbidity (SRQ-20 caseness) was 80.6%, while 72.6% and 77.8% were found to be positive for depression and anxiety symptoms respectively on the HADS. Overall, 84.5% of the respondents had at least one type of psychiatric morbidity. Age, marital status, self-reported physical and mental health, previous mental illness, imprisonment status, prison accommodation, prison meal, and health care services were found to be significantly associated with depression, anxiety or general psychiatric morbidity. Self-reported poor current mental health was the only variable that predicted all the three types of psychiatric morbidity. CONCLUSION: Prisoners in this study, and as in previous reports, had high prevalence rates of psychiatric morbidity. Thus, prisoners have a need for regular psychiatric screening and treatment. The consequences of untreated psychiatric morbidity and the need for improved health care services and infrastructure in the prison were discussed.
