| ABSTRACT | |||
| The aim of this study was to develop a scale for assessing and
predicting adolescents' physical activity behavior in Spain and Luxembourg
using the Theory of Planned Behavior as a framework. The sample was comprised
of 613 Spanish (boys = 309, girls = 304; M age =15.28, SD =1.127) and 752
Luxembourgish adolescents (boys = 343, girls = 409; M age = 14.92, SD =
1.198), selected from students of two secondary schools in both countries,
with a similar socio-economic status. The initial 43-items were all scored
on a 4-point response format using the structured alternative format and
translated into Spanish, French and German. In order to ensure the accuracy
of the translation, standardized parallel back-translation techniques were
employed. Following two pilot tests and subsequent revisions, a second order
exploratory factor analysis with oblimin direct rotation was used for factor
extraction. Internal consistency and test-retest reliabilities were also
tested. The 4-week test-retest correlations confirmed the items' time stability.
The same five factors were obtained, explaining 63.76% and 63.64% of the
total variance in both samples. Internal consistency for the five factors
ranged from α = 0.759 to α = 0. 949 in the Spanish sample and
from α = 0.735 to α = 0.952 in the Luxembourgish sample. For both
samples, inter-factor correlations were all reported significant and positive,
except for Factor 5 where they were significant but negative. The high internal
consistency of the subscales, the reported item test-retest reliabilities
and the identical factor structure confirm the adequacy of the elaborated
questionnaire for assessing the TPB-based constructs when used with a population
of adolescents in Spain and Luxembourg. The results give some indication
that they may have value in measuring the hypothesized TPB constructs for
PA behavior in a cross-cultural context.
