Resistance to Peer Influence Scale

Number of Questions
Creator(s) of Tool
Steinberg, L. & Monahan, K. 2007. Age Difference in Resistence to Peer Influence. Development Psychology, 43(6) 1531-1543.; MacArthur Juvenile Capacity Study
Scoring / Benchmarking
Responses are coded on a 4-point scale, ranging from "really true" for one descriptor to "really true" for the other descriptor, and averaged. Higher scores indicate greater resistence to peer influence.

Scoring instructions: Score each item from 1 to 4 (reading left to right on the instrument). Reverse-score items 2, 6, and 10. Sum the scores for valid responses and divide by the number of valid items. It is recommended that at least 7 items have valid responses.

Higher scores indicate greater resistance to peer influence.
Background / Quality
Items were generated by a group of developmental psychologists with expertise in adolescent psychosocial development and pilot tested with small samples of high school students and college undergraduates.

Examination of the scale’s internal consistency was conducted within each of the four samples separately, using both Cronbach’s alpha as well as confirmatory factor analysis. These analyses indicate that the measure demonstrates adequate and comparable reliability within each sample (Cronbach’s alpha was .70, .76, .74, and .73)
Is there a cost associated with this tool?

The Resistance to Peer Influence measure presents respondents with a series of 10 pairs of statements and asks them to choose the statement that is the best descriptor (sample item: "Some people go along with friends just to keep their friends happy" BUT "Other people refuse to go along with what their friends want to do, even though they know it will make their friends unhappy").

 After indicating the best descriptor, the respondent is then asked whether the description is "Really True" or Sort of True"
