Italian Psychometric Validation of the Multidimensional Students’ Health-Promoting Lifestyle Profile Scale
Health and well-being are commonly needed
to achieve a sufficient or satisfactory level of existence, and they are
essential concepts for health promotion. Furthermore, health has been defined
as a positive dynamic process and not merely an extension of illness-avoidance
behavior.
A health-promoting
lifestyle is a multidimensional pattern of self-initiated actions and
perceptions that serve to maintain or enhance an individual’s level of
wellness, self-actualization, and fulfillment. Practicing daily
health-promoting lifestyle behaviors is an important component of maintaining
and improving health.
The present study
examined the factorial structure and assesses the psychometric properties of
the adapted multidimensional Health-Promoting Lifestyle Profile II (HPLP-II) Scale,
considering a sample of Italian university students who participated to an
online survey. The study was conducted in the middle of
the 2015-2016 academic year (around 75 days) to avoid seasonal holidays and
stressful periods that are usually concentrated at the beginning of the
semester (because of the novelty of the challenge of college) and the end of
the semester (because of examinations). In this period, 642 students responded
to the request to participate to the survey, of which 517 (80.53%) answered
almost all required information in the online questionnaire.
Internal
consistency was assessed for the entire instrument as well as for each
subscale. The HPLP-II Scale showed a high overall internal consistency: the
Cronbach’s α coefficient for the
total 52-item scale was 0.90. Four of the six subscales were associated with
good values of the Cronbach’s α coefficient, whereas two subscales had lower
values. Hence corrected item-total correlation was calculated and 26 items that
decreased the scale’s reliability were deleted. The remaining 26 items were
first subjected to Principal Component Analysis that suggested a conceptually
meaningful five-factor model. This result was further supported by the first-order
confirmatory factor analysis, in which all the factor loadings were
statistically significant.
In conclusion, the
results indicate that the HPLP-II Scale seems to be a valuable tool for
studying representations of the promotion of well-being and lifestyle, and its
Italian version could be applied to the Italian population as a tool to
evaluate a health-promoting lifestyle.
