- Populations: Middle Adolescents
- Age ranges: 16-17
- Languages: English
- Countries: Israel
Items
Subscales
- Attitude, 8 Items
- Peer Norms, 16 Items
- Perceived-Control, 4 Items
Example Items
- “If a couple goes on a date, and the boy is initiating a sexual intercourse with the girl, and she is resisting, should he persist?”
- “To what degree do you think your close friends believe that if a [boy/girl] initiates a [make-out/sexual intercourse] and the [boy/girl partner] [is passive/resists], s/he should persist”
- “if [I/my-partner] initiate a sexual act (make-out or intercourse), and [my-partner is not/I am not] interested, I can always stop it”
Responses
Items used a 5 point Likert-type scale, 0 = should certainly not, 4 = should certainly persist.

Team comments
The Perceived Control subscale did not reach our threshold for adequacy in terms of internal consistency.

Definitions
Face validity: How well a measure appears to represent the construct it is supposed to be measuring.
Convergent validity: How well a measure correlates with other hypothetically-related measures.
Construct validity: The extent to which a measure reflects the construct it was designed to evaluate.
Internal consistency: The extent to which items in a scale capture aspects of the same construct.
Test-retest: The degree to which measurement scores are consistent over a short period of time (usually 2 weeks).
Readability: The ease with which a reader can understand the questionnaire items.
Key
- Green: Meets validation criteria
- Red: Does not meet validation criteria
- Unknown: Evidence not available
