Testing the self-efficacy of my volunteers

I needed to know which type of self efficacy my volunteers had (high/low) towards physical activity. I used  Health-Specific Self-Efficacy Scales created by Ralf Schwarzer & Britta Renner to get a self-efficacy rating of my volunteers. It worked out that 4 had high self-efficacy towards physical activity and 4 had low self-efficacy towards physical activity. The questionnaire can be found at
