| Summary: | INTRODUCTION: Number of active smokers in
Malaysia is increasing despite availability of stop smoking
clinics and smoking cessation medications. Thus, the
practice of the healthcare professionals involved in
providing smoking cessation intervention using evidence based guidelines needs to be assessed using validated
assessment tool. Newly invented reliable and valid
questionnaire is needed to be develop locally. This study
aimed to develop and validate a newly modified
questionnaire to assess the knowledge, attitude and
practice of medical doctors based on national smoking
cessation guidelines and factors contributing to the score.
METHODS: The 22 items consist of mixture of true/false
choice questions and Likert scaling response based on
domain of 5A’s (ask, assess, advice, assist, arrange) and
5R’s (relevant, risks, rewards, roadblocks, repetitions) of
the national stop-smoking guideline. The questionnaires
were distributed to 131 primary care doctors. Reliability
was determined using Cronbach’s alpha for internal
consistency while construct validity was assessed using
factor analysis. RESULTS: A high degree of internal
consistency was observed for these 22-items (Cronbach’s
alpha = 0.87), with good knowledge subscale (0.72),
attitude subscale (0.58) and practice subscale (0.92).
Factor analysis showed five meaningful components
which represent the smoking cessation framework.
DISCUSSION: This study indicates that this
questionnaire is most reliable and valid tool to assess the
knowledge, attitude and practice on stop smoking
guidelines compared to previously available
questionnaire. |
