BackgroundKnowledge and awareness about childhood autism is low among health workers and the general community in Nigeria and other Sub-Saharan African countries. Poor knowledge and awareness about childhood autism, especially among health workers can compromise early recognition and interventions which had been known to improve prognosis in children with autism. In formulating policy and designing interventions for these children, there is need to develop a reliable tool that can be used in assessing baseline knowledge about childhood autism among health workers and the impact that future continued education and awareness campaign may have on such baseline knowledge. Knowledge about childhood autism among health workers (KCAHW) questionnaire was designed for this purpose.MethodsThe KCAHW questionnaire is a nineteen (19) item self-administered questionnaire that is divided into four domains. KCAHW questionnaires were distributed to fifty (50) psychiatric nurses involved in community mental health services in South-Eastern Nigeria to complete. After two weeks period, the KCAHW questionnaires were re-administered to the same fifty (50) psychiatric nurses to assess their knowledge about childhood autism and to assess the test-retest reliability and internal consistency of this questionnaire.ResultsKCAHW questionnaire showed good test-retest reliability when the mean domain and total scores at first and second time administration were compared. The four mean domain scores and the mean total scores at first and second time administration were significantly correlated. The questionnaire also had a good overall internal consistency when the mean scores of the four domains were correlated with mean total scores (Cronbach's alpha = 0.97).ConclusionThe KCAHW questionnaire is a reliable tool for assessing knowledge of health workers about childhood autism. It would be a useful tool in improving early recognition of features of autism among affected children in Sub-Saharan African and other developing countries of the world where knowledge and awareness about childhood autism is low.

Background: In designing programs to raise the community level of awareness about childhood autism in sub-Saharan Africa, it is logical to use the primary healthcare workers as contact point for education of the general public. Tertiary healthcare workers could play the role of trainers on childhood autism at primary healthcare level. Assessing their baseline knowledge about childhood autism to detect areas of knowledge gap is an essential ingredient in starting off such programs that would be aimed at early diagnosis and interventions. Knowledge of the healthcare workers on availability of facilities and law that would promote the required interventions is also important. This study assessed the baseline knowledge about childhood autism and opinion among Nigerian healthcare workers on availability of facilities and law caring for the needs and rights of children with childhood autism and other developmental disorders.

Background: Because of their peculiar sociocultural background, healthcare workers in subSaharan African subcultures may have various conceptions on different aspects of autism spectrum disorders (ASD), such as etiology, treatment and issues of prognosis. These various conceptions, if different from current knowledge in literature about ASD, may negatively influence help-seeking behavior of parents of children with ASD who seek advice and information from the healthcare workers. This study assessed the opinions of healthcare workers in Nigeria on aspects of etiology, treatability and preventability of childhood autism, and relates their opinions to the sociodemographic variables.

The prevalence of autism spectrum disorder (ASD) among sub-Saharan African children with intellectual disability is about 0.7% more than three decades ago. During this period, the prevalence of ASD has been on the increase worldwide. Studies are not available in recent times addressing epidemiology of ASD among sub-Saharan African children. The present study assessed the prevalence of ASD among Nigerian children with intellectual disability. Forty four children with intellectual disability were assessed for diagnosis of childhood autism based on criteria specified in F84.0 section of International Classification of Diseases, Tenth Edition (ICD-10) Diagnostic Criteria for Research. Five (11.4%) of the children studied met the diagnostic criteria for childhood autism. Male/female ratio was 4:1. There is need for large scale epidemiological studies of ASD among sub-Saharan African children to clearly define the inter-relationship between ASD and intellectual disability in this population and to help in health care policy formulation.
