The main goal of our research was to develop a new measure of persistence and
to assess its construct validity and psychometric proprieties. First, we
discuss the history of the psychological construct of persistence, defined
here as the tendency to remain engaged in specific goal-related activities,
despite difficulties, obstacles, fatigue, prolonged frustration or low
perceived feasibility. The developed scale, measuring motivational
persistence, contains three-factors: long-term purposes pursuing, current
purposes pursuing and recurrence of unattained purposes. The results of the
two validation studies conducted, employing both exploratory and confirmatory
factor analysis, advocate the hypothesized structure. Also, the Pearson and
canonical correlations between the three factors of the new self-report scale
and other three related measures (and their factors) indicate good levels of
convergent and divergent validity of the new scale.
