Abstract
Background and purpose
Measuring the adolescent awareness of healthy lifestyle behaviors and the self-efficacy
needed to change behaviors is an important step in improving the health of this population.
The Healthy Lifestyle Beliefs Scale is one such instrument, and it has been used to
measure the healthy behaviors of adolescents in the United States. This study aims
to extend this instrument by evaluating its validity and reliability in Turkish adolescents.
Methods
This methodological, descriptive, correlational study was conducted on 843 adolescents
between October 2019 and November 2019. Data were collected using a socio-demographic
information form and the Healthy Lifestyle Beliefs Scale. Factor analysis, Cronbach's
alpha, and item–total score analysis were used for the data analysis.
Results
The scale consisted of 16 items and three subscales. The three subscales were found
to explain 57.66% of the total variance. The total factor loading was >0.30 in both
exploratory and confirmatory factor analyses. In the confirmatory factor analysis,
all the goodness of fit indexes were >0.91, and the root mean square error of approximation
was <0.08. The Cronbach's alpha coefficient for the overall scale was 0.90, and the
Cronbach's alpha values for the subscales were 0.79–0.84.
Discussion
The Healthy Lifestyle Beliefs Scale for adolescents was found to be a valid and reliable
measurement tool for the Turkish sample.
Practice implications
Determining the healthy lifestyle beliefs of adolescents can contribute to the creation
of healthy lifestyle behaviors.
