Can any one suggest me how i can assess sports specific self efficacy? Is there a valid tool available? Can i modify the items of existing tools measuring a specific type of self efficacy?
There is a lot of scales that assess self efficacy. A lot of them were developed by the workgroup of Prof Ralf Schwarzer, wo developed the well known Health Action Process Approach Model (HAPA). You can find assessment tools on their website for free: http://www.hapa-model.de/
Most of them are not sport specific but can be used to assess self efficacy regarding physical activity.
I know a german scale for the specific assessment of self efficacy for physical activity but it is only published in german. You can find it here: https://www.sport.uni-freiburg.de/de/institut/Arbeitsbereiche/psychologie/messinstrumente
I measured self efficacy for physical activity as described in the following paper.
In the paper the items are fully described on english so you could use them citing the paper.

Moritz Petzold thank you for the response. But i am looking for a measure to assess self efficacy in sports (generic) and not for an aspect of sports (eg physical activity).
I think i don't understand what you search. The scales are measuring overall self efficacy for physical activity. Or so you search something for specific forms of sports?
this research has used the asked measure
