Prevalence, Levels and Correlates of Intellectual Disability among Adolescents Incarcerated in a Correctional Facility in Kaduna, North-Western Nigeria

Abstract

BACKGROUND Adolescents with intellectual disability are disproportionately represented within correctional facilities. Studies have shown that such adolescents are vulnerable to manipulation and influence including coercion into homosexual relationships, as well as to being victims of homicide compared to others. However, there are few studies on intellectual disability among adolescents in correctional facilities in Northern Nigeria. This study thus aimed to assess the prevalence, levels and correlates of intellectual disability among adolescents in a correctional facility in Kaduna, Northwestern, Nigeria. MATERIALS AND METHODS This cross-sectional study was conducted among all the adolescents incarcerated at the Borstal Training Institution in Kaduna, North-western Nigeria between March and June 2018 who gave informed consent/assent. Data collection was done using a sociodemographic questionnaire; Raven’s Progressive Matrices (RPM); Adverse Childhood Experiences (ACE) Questionnaire and Perceived parental support questionnaire. RESULTS The 93 participants aged 13 years to 19 years were all males with a mean age of 17.71 years (SD ±1.19). The majority (88.2%) were below average intellectually while 58.1% were intellectually defective. Participants with below-average IQ had experienced parental death (χ2 = 4.099, p=0.043), had mothers with less than 12 years of education (χ2 = 5.653, p=0.015) and scored lower on perceived combined parental support (t=-4.704, p=0.032), maternal (t=-4.334, p=0.000) and paternal support (t=-3.506, p=0.001). CONCLUSIONS Intellectual disabilities are prevalent among adolescents in incarceration. There is a need to put in place programs for the identification of such adolescents in our correctional facilities so that programs which minimize the disability while emphasizing the adolescents' strengths can be instituted thus probably reducing their representation in the prison population as well as enhancing the success of rehabilitation back into the society. In addition, identified correlates should be incorporated into targeted prevention strategies for vulnerable adolescents effectively and sustainably to reduce their occurrence.
