Background: The SI! Program promotes cardiovascular health through a
multilevel school-based intervention on four lifestyle-related
components: diet, physical activity, understanding the body and heart,
and management of emotions. We report here the development and
validation of the KAH (knowledge, attitudes and habits)-questionnaire
adapted for elementary school children (6-7 years old) as a tool for the
forthcoming evaluation of the SI! Program, where the KAH scoring will be
the primary outcome. The efficacy of such an intervention will be based
on the improvements in children's KAH towards a healthy lifestyle.
Methods: The questionnaire validation process started with a pool of
items proposed by the pedagogical team who developed the SI! Program for
elementary school. The questionnaire was finalized by decreasing the
number of items from 155 to 48 using expert panels and statistical tests
on the responses from 384 children (ages 6-7). A team of specialized
psychologists administered the questionnaire at schools providing
standard directions for the final administration. The internal
consistency was assessed using Cronbach's a coefficients. Reliability
was measured through the split-half method, and problematic items were
detected applying the item response theory. Analysis of variance and
Tukey's test of additivity were used for multiple comparisons.
Results: The final KAH-questionnaire for elementary school children
should be administered to children individually by trained staff. The 48
items-questionnaire is divided evenly between the 4 components of the
intervention, with an overall Cronbach's a = 0.791 (a = 0.526 for diet,
a = 0.537 for physical activity, a = 0.523 for human body and heart, and
a = 0.537 for management of emotions).
Conclusions: The KAH-questionnaire is a reliable instrument to assess
the efficacy of the SI! Program on instilling healthy lifestyle-related
behaviors in elementary school children.
