Medicines are cost-effective interventions for the treatment and management of health problems. This research was carried out to determine the common health problems and medicine-use practices in treating health problems in Lamingo, Jos, Nigeria. A total of 109 households covering 676 individuals were recruited and followed up for a period of one month between 6 November 2010 and 11 December 2010. A structured interview was conducted on weekly visits to households to identify illnesses suffered by household members and treatment given. The results showed that 146 common health problems representing 1.3 cases per household per month were found. The cost of treatment per household per month was found to be $14.7. Infectious and parasitic diseases (44.6%), diseases of the digestive (11.0%) and respiratory system (9.6%) were common in the community. Self-medication was common (34.6%) and the patent medicine stores were the most common sources of medicines. Common classes of medicines used by community members were analgesics (23.6%), antimalarials (17.9%) and antibiotics (14.2%). Factors that influenced choice of treatment were previous knowledge and experience of family members with service provider and treatment (44.4%), cost (18.9%) and severity of condition (16.7%). There is, therefore, high occurrence of health problems and self-medication practices in the Lamingo community.

The present study assessed the dimensionality and item difficulty targeting to person ability of HKAPIUM scale using Rasch Wright map approach. A HKAPIUM instrument (Cronbach’s alpha = 0.71) containing eighteen (18)-items was administered to 121 trained healthcare professionals involved in the management of uncomplicated malaria in 24 selected primary health care (PHC) facilities in Plateau state, Nigeria. The respondents filled and returned the instrument and the data was analyzed using Bond&Fox software®. The Rasch principal components analysis (Rasch-PCA) of the item residuals indicated variance explained values of 52 (knowledge), 41.1 (attitudes), and 55.4 (practices) and eigenvalues of the first contrast as 1.2, 1.8, and 1.5, respectively, which were within acceptable values thatindicated the unidimensionality of the three constructs of the HKAPIUM scale. The result showed moderate items difficulty levels for all the three constructs. The mean person ability levels of respondents with-respect-to knowledge-related items were low, while their mean person ability levels in endorsing the attitudes and practices-related items were good. The study revealed unidimensionality of the 3 constructs of HKAPIUM scale, with observed mismatch between item difficulty levels of the constructs with most of the person ability levels of the respondents.
