| Summary: | Introduction
Perception is an essential factor influencing smoking among
adolescents. Thus, a valid tool for measuring perception is a requisite in smoking
studies. This study further establishes the validity and reliability of a Malay
language version of the Perception Towards Smoking Questionnaire (BMPTSQ)
for assessing the perception of smoking among secondary school-going
adolescents in Malaysia.
Methods
We administered the BM-PTSQ to 669 secondary school students selected
through multistage sampling; 60% of respondents were male (n=398), and 69.9%
(n=463) were from rural areas. Respondents were aged 13–16 years, 36.4%
(n=241) were 13 years, 40.0% (n=265) were 14 years, and 23.6% (n=156) were
16 years old. We used parallel and exploratory factor analysis (EFA) to determine
the domains of the questionnaire. In addition, we also employed EFA, confirmatory
factor analyses (CFA), and Cronbach's alpha to evaluate the construct validity and
reliability of the BM-PTSQ.
Results
EFA and parallel analysis identified two domains in the BM-PTSQ that
accounted for 62.9% of the observed variance, and CFA confirmed the two-domain
structure. The two domains' internal consistency scores ranged from 0.702 to
0.80, which suggested adequate reliability.
Conclusions
The BM-PTSQ has acceptable psychometric validity and is appropriate
for assessing smoking perception and intention among Malaysian secondary
school-aged youth. Researchers should further evaluate this tool's applicability
in a more sociodemographically diverse population. |
