Reliability Title

The reliability and validity for the initial testing of the SHOTS survey with over 600 parents was very strong. In addition, in a second study using the SHOTS survey (Baker, 2010), the reliability and validity measures were equally as strong as the initial study.

Internal Consistency: Internal consistency is supported in two studies with Cronbach's alpha's of .93 (Table 1)

Temporal Reliability: Support for stability across time was demonstrated with a Pearson's R of .851 (Niederhauser, 2010)

A detailed description of the reliability and validity can be found in the following manuscript:

A $50 processing fee and a licensing agreement is required to use the SHOTS survey. In addition, a licensing agreement is required for incorporation of the SHOTS survey into computer software. Contact Dr. Victoria Niederhauser (vniederhauser@me.com) regarding licensing agreements. Inquire Now
