Quizplus · Accepted Answer

The nurse investigator is attempting to establish contrasted-groups validity by administering the instrument to two groups with contrasting characteristics - those attending an Alcoholics Anonymous meeting and those belonging to a religious sect known for abstinence from alcohol. This will allow the investigator to use the scores of the two groups to assess the validity of the instrument in differentiating between individuals who are at risk for alcohol-related problems and those who are not.
