Mean score = 4.50 – 5.00 means leadership of the Chiefs of Health Centers was at a very high level Mean score = 3.50 – 4.49 means leadership of the Chiefs of Health Centers was at a high level Mean score = 2.50 – 3.49 means leadership of the Chiefs of Health Centers was at a moderate level Mean score = 1.50 – 2.49 means leadership of the Chiefs of Health Centers was at a low level Mean score = 1.00 – 1.49 means leadership of the Chiefs of Health Centers was at a very low level Part 3: Teamwork of the Chiefs of Health Centers in which researcher uses the questionnaire constructed by Atchara Suepsangad (1997) based on the concept of Woodcock (1989) to evaluate teamwork of the Chiefs of Health Centers.

The questionnaire relating to teamwork of the Chiefs of Health Centers consists of 10 parts and 67 questions as follows.

Mean score = 4.50 – 5.00 means teamwork was at a very high level Mean score = 3.50 – 4.49 means teamwork was at a high level Mean score = 2.50 – 3.49 means teamwork was at a moderate level Mean score = 1.50 – 2.49 means teamwork was at a low level Mean score = 1.00 – 1.49 means teamwork was at a very low level Reliability Assessment of Research Instrument Reliability assessment of research instrument was done by analyzing content validity of the questionnaires and calculating reliability value of the research tool. The process was as follows. 41 1. Content validity: The questionnaire relating to leadership of the Chiefs of Health Centers constructed by Kirati Rungchaeng (2000) and the questionnaire relating to teamwork constructed by Atchara Suepsangad (1997) were assessed for their content validity and improved in accordance with the suggestions of experts. Researcher did not conduct self-assessment of both questionnaires. 2. Reliability: Researcher tried out the questionnaire relating to leadership of the Chiefs of Health Centers constructed by Kirati Rungchaeng (2000), with reliability value of 0.97, and the questionnaire relating to teamwork constructed by Atchara Suepsangad (1997), with reliability value of 0.96, with 30 Chiefs of Health Centers who are working in Chachengsao province and have similar characteristics to the sampling group and find reliability value by using Cronbach’s coefficient alpha (Yuwadee Ruecha et al., 2000, p. 127) as follows. ⎡ s 2 ⎤ n ∑ i α = ⎢1 − 2 ⎥ n − 1 s ⎣⎢ t ⎦⎥ α = Reliability coefficient of questionnaire n = Number of data of questionnaires 2 si = Variance of score of each question 2 st = Variance of total score of all questionnaires It was found that overall Cronbach’s alpha coefficient of the questionnaire related to leadership of the Chiefs of Health Centers was equivalent to .92 whereby charismatic influence is .70; individualized consideration is .69; intellectual stimulation was .87; and inspirational motivation was .83. The questionnaire related to teamwork of the Chiefs of Health Centers was equivalent to .96 where balance in roles equals to .81; clear purposes and conformity to goals was .74; openness and confrontation is .83; mutual support and sincerity was .83; cooperation and conflict was .78; flexible method of work conduct was .81; regular teamwork revision was .86; personnel development was .74; good relations within a group was .69; and effective communication was .73. Then, all questionnaires were examined by thesis 42 advisors in order to check for accuracy and appropriateness of language, congruence with research objectives, and content coverage. Suggestions obtained from the thesis advisors were used for further improvement of the questionnaires. The improved questionnaires were, then, examined by experts for accuracy and the obtained suggestions were used for additional improvement. Data Collection Data collection in this research contained the following steps. 1.

Then, researcher collected the data by asking the target groups to fill out information at the same time. If they had any doubts, the target groups could immediately ask researcher. Research spent time with each group about 30 minutes and the total duration for data collection was 3 weeks. 5.

The study of leadership and teamwork of the Chiefs of Health Centers was analyzed by using basic statistics, including percentage, mean and standard deviation. 3. The study of the relationship between leadership and teamwork of the Chiefs of Health Centers in Chonburi province was analyzed by using analytical ststistics in analyzing Pearson product moment correlation coefficient, by interpreting coefficient alpha (r) as follows (Prakong Kannasoot, 1992). Value from 0.70 to 1.00 had correlation value in a high level Value from 0.30 to 0.69 had correlation value in a moderate level Value from 0.00 to 0.29 had correlation value in a low level .
