| Abstract: | ObjectivesA German version of the Self-reported Habit Strength Index (SRHI) for both sports and everyday physical activity (PA) was validated against subjective and objective criterion measures of PA.Design and methodData were obtained from 260 participants (21.4% women) in study 1 and 86 participants (58.1% women) in study 2. Both studies assessed habit strength for PA (sports and everyday PA) by the SRHI and PA by the Baecke Questionnaire (Sport, Leisure and Work Index) as subjective criterion measure, as well as by accelerometry (Step Activity Monitor or GTM1 Actigraph) as objective criterion measure. Bivariate correlations as well as path analyses were computed for the associations between the SRHI scores and subjective and objective criterion measures of PA.ResultsHighest associations for subjective criterion measure were found for habit strength for sports and the Sport Index in both studies. The Leisure Index was predicted by habit strength for sports and everyday PA. For objective criterion measures, habit strength for sports was most significantly associated with total PA in study 1 and moderate intense PA in study 2. Habit strength for everyday PA was a significant predictor of moderate intense and total PA in study 1 and low intense PA in study 2.ConclusionThe present studies replicated high internal consistencies of the SRHI for sports and everyday PA and could partially confirm their validity with subjective and objective criterion measures. The SRHI for sports seems to be more robust than the SRHI for everyday physical activity. |
