Evidence of Technical Quality
Populations for which technical quality evidence has been collected

Evidence in based on a multistage cluster sample of 6th, 8th, and 11th grade students in Oregon.

Reliability evidence

Internal consistency estimates (Cronbach's alpha) reported separately for subscales and by grade and gender. Estimates ranged from 0.50 to 0.93.

Validity evidence
Evidence based on content
The initial item pool was compiled from existing instruments. A second wave of pilot testing was used to look for empirical evidence of redundance (based on inter-item correlations) or lack of discrimination (low variance).
Evidence based on response processes
Items were pilot tested using cognitive interviews to remove ambiguous or unclear items.
Evidence based on internal structure
Principal component analysis (Arthur et al., 2002) was used to determine scale dimensionality.
Evidence based on relations with other variables
Relationships between risk and protective factor scales and self-reports of drug abuse and delinquency were in the anticipated direction (Arthur et al., 2002).
