Thesis advisor: Larry H. Ludlow / Item Response Theory (IRT) is a contemporary measurement technique which has been used widely to model testing data and survey data. To apply IRT models, several assumptions have to be satisfied. Local item independence is a key assumption directly related to the estimation process. Many studies have been conducted to examine the impact of local item dependence (LID) on test statistics and parameter estimates in large-scale assessments. However, in the heath care field where IRT is experiencing greater popularity, few studies have been conducted to study LID specifically. LID in the health care field bears some unique characteristics which deserve separate analysis. In health care surveys, it is common to see several items that are phrased in a similar structure or items that have a hierarchical order of difficulties. Therefore, a Guttman scaling pattern, or a deterministic response pattern, is observed among those items. The purposes of this study are to detect whether the Guttman scaling pattern among a subset of items exhibit local dependence, whether such dependence has any impact on test statistics, and whether these effects differ when different IRT models are employed. The score-based approach - forming locally dependent dichotomous items into a polytomous testlet - is used to accommodate LID. Results from this dissertation suggest that the Guttman scaling pattern among a subset of items does exhibit moderate- to high-degree of LID. However, the impact of this special LID is minimal on internal reliability estimates and on the unidimensional data structure. Regardless of which models are employed, the dichotomously-scored person ability estimates are highly correlated with the polytomously-scored person ability estimates. However, the impact of this special LID on test information differs between Rasch models and non-Rasch models. Specifically, when only Rasch models are involved, test information derived from the LID-laden data is underestimated for non-extreme scores; whereas, when non-Rasch models are used, the opposite finding is reached –that is, LID tends to overestimate test information. / Thesis (PhD) — Boston College, 2008. / Submitted to: Boston College.

During a 12-months period from 1 April 1966 to 31 March 1967 all infants born of Maori and Polynesian Pacific islander parentage domiciled within the Auckland Health District were included in a longitudinal infant health survey, and those that came under the supervision of the public health nurses in the district were followed up wherever practicable for a period of 12 months. The survey was primarily concerned with the social, biological, and operational (personal health services) factors likely to affect the health status and growth progress of infants of these migrant families undergoing the social processes of urbanisation--Part 1 - Introduction.

This study was aimed at identifying factors that are associated with the implementation of the nutrition surveillance programme in Zambia. The objective of the study was to determine the knowledge, attitude and practice of district level health personnel about nutrition surveillance.
