A Model for Development of Prevention and Controlling Effectiveness of Dengue Haemorrhagic Fever of Village Health Volunteer Leader in Yasothon Province.

Abstract

This research aimed to (1) study factors affecting the effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader in Yasothon Province, (2) formulate adevelopment model of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader in YasothonProvince,and(3) implement and evaluate the effectiveness of developed model of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader in YasothonProvince. The research procedures were divided into threestages. The first stage was a quantitative research, the researcher investigated factors which affected the effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader by formulating a model of effectiveness of prevention and controlling as an outcome variable. Two hundred and seventy six subjects (276) of village health volunteersleader involved in this study were recruited using a rational ratio of each districtfrom nine districts in Yasothon Province. The required data were collected using the questionnaire and data analysis was performed using computer programs. Statistics used for hypothesis testing included Structural Equation Model: SEM by LISREL. Pearson correlation and path analysis were used for analysis of correlations between factors affecting the effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader, using a level of statistical significant at .05. In the second stage, the researcher constructed the development model the effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteerleaderinYasothonProvince by using the study result from the first stage. Twenty involved people were participated in the workshop to co-operatively criticized and evaluated the effectiveness of the formulated model by using focus groups, brain storming and presentation to achieve the conclusions and recommendations for improving the effectiveness of the developed model. In the third stage, the researcher implemented the model. The model was evaluated by 28 subjects and 30 control group in order to compare the effectiveness between two groups. The major findings revealed the followings: 1. The developed causal factors showed harmony with the empirical data. Four causal factors effects on the effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteer leader in YasothonProvincewere found in high to low ranking including: team working (0.15) participation(0.12), role perception (0.10) and leadership (0.03). 2. The development model of the effectiveness of prevention and controlling of
dengue haemorrhagic fever of village health volunteerleader in YasothonProvinceconsisted of nine activities : team working, life position,mysterious pictures,top-eggs, role and duty, role playing,seek for leadershipand mentors activity. 3. The evaluation results showed higher effectiveness of prevention and controlling of dengue haemorrhagic fever of village health volunteerleader in Yasothon Province as a whole and in twoaspects: more effectiveness than before implementation of model. Breteau Index (B.I.) value and a numberof patient withdenguehaemorrhagic Fever were decreased at the .05 level of statistical significance. Keywords : Development model, Effectiveness, Village health volunteer leader
