The validation of knowledge, attitude and practice questionnaire on breast cancer among women attending family medicine clinic, HUSM.
Masters thesis, Universiti Sains Malaysia.
Abstract
Introduction: Breast cancer is the leading cause of cancer deaths among Malaysian
women. Breast cancer is treatable if detected early, and breast screening has proven
to be the best way for early detection of breast cancer. However, poor awareness and
understanding of the disease contributes to the deaths of many women in Malaysia
Therefore, there is a need to develop a valid and reliable instrument to measure the
knowledge, attitude and practice (KAP) on breast cancer and screening behaviours
among Malaysian women.
Objective: The purpose of this study was to validate the Malay language version of
knowledge, attitude and practice questionnaire (KAPQ) on breast cancer among
women attending Family Medicine Clinic (FMC), Hospital Universiti Sains
Malaysia (HUSM).
Methodology: This was a cross sectional study. The respondents were 227 women
attending FMC, HUSM. They were selected using systematic random sampling. The
questionnaire has been developed based on literatures and several expert opinions.
The questionnaire was then self administered by the respondent. Analysis included
descriptive statistics of all the study variables, determination of the construct validity
using factor analysis and internal consistency reliability using Cronbach's alpha
Results: All of the 227 respondents were analyzed. The mean (SD) age of the
respondents was 29.6 (9.9) years. Majority of the respondents (91.6%) were Malay
and nearly half of them (47.1%) were educated to upper secondary school. Factor
analysis yielded five factors for knowledge domain with eigenvalue greater than one, five factors for attitude domain and only two factors for practice domain. All of the
factors were loaded from 0.477 to 0.872. Meanwhile, Cronbach's alpha reliability
coefficients for all domains were ranged from 0.636 to 0.818.
Conclusion: The Malay language version of KAPQ on breast cancer was found to
be a valid and reliable instrument to be used among Malaysian women. It can be
used easily to measure the KAP on breast cancer and screening behavior, and for
health promotion planning interventions. For greater applicability, it is recommended
that this instrument be tested among ethnically diverse populations.
