スポーツ・プログラム参加者のアドヒアランスに関する研究 : 計画的行動理論(Theory of planned behavior)の適用

The purpose of this study is to apply the theory of planned behavior to clarify adherence
of sports program participants who were altendants of 6-month program in community-based
sports facility. A questionnaire survey was conducted with a total of 1，960 participants of
6-month sports program. The respondents consist of 1，578 adherers and 382 non-adherers
and 1，115 usable questionnaires were obtained，resulting is a response rate of 56.9 percent.
In order to consider effects of the period of duration，th e samples who first participated in
this program were analyzed. As a result，108 participants were continuously next 6-month
program participants (adherers) and 74 participants were not continuously them (non-adherers).
Multiple regression analysis were utilized to assess the relationships behavior (continuous
participation) intention and three factors that are attitude toward behavior，subjective norm
(percieved social support)，and percieved behavioral control.
The major findings are summarized follows:(1)The theory of planned behavior is
applicables to examine adherence of sports program participants. (2) Multiple regression
analysis revealed significant relationships between behavior (continuous program participation)
intention and attitude toward behavior (β=.193，P less than .01) and percieved behavioral
control (β=-.269，p less than .01)，but subjective norm was not significant(R=.394，P less
than .01). (3) Continuity-withdrawal behavior (next 6-month program) related to percieved
behavioral control (γ=-.249，p less than.01) as well as behavioral intention (γ=.534，
p less than .01). Discussion focused on implications for progarm management and
methodological issues concerning the theory of planned behavior as applied to adherence research.
