  • a The “Sum of Informational Sources” score was computed by adding one point for each “yes” response to questions of whether the respondent had received information about PA 161 from six different sources (see Table 2 for wording of questions). Scores ranged from 0=no sources of information to 6=information received in all six ways.

  • b The “Familiarity Index” score was computed by averaging the responses to the four familiarity questions (see Table 3 for wording of questions). Response options ranged from 1=strongly disagree (most negative attitude) to 5=strongly agree (most positive attitude).

  • c The “Attitude Index” score was computed by averaging the responses to the five attitudinal questions (see Table 4 for wording of questions.) Response options ranged from 1=strongly disagree (most negative attitude) to 5=strongly agree (most positive attitude).

  • d The “Sum of Knowledge” score was computed by adding one point for each “yes” response to the two knowledge questions (see Table 5 for wording of questions). Scores ranged from 0=no knowledge to 2=highest level of knowledge.

  • e The “Single Item: Knowledge” score was measured with responses to the statement “I know what PA161 is all about.” Response options were on a five-point scale from 1=disagree strongly to 5=agree strongly.

  • F “Interest to Know” was assessed with a single item: “Are you interested in more information about the PA 161 program?” Correlations with this variable were determined with contingency coefficients. To compute the contingency coefficient for this variable and the variable “Age,” “Age” was categorized by quartiles of responses into four groups (18–22 years; 23–25 years; 26–40 years; 41–70 years). To compute the contingency coefficient for this variable and the average attitude scores, the average attitude scores were categorized by quartiles of responses into four groups (<3; 3–3.5; 3.51–4.17; >4.17).

  • g “Interest to Participate” was measured with responses to the statement “I would like to participate in a PA161 program.” Response options were on a five-point scale from 1=disagree strongly to 5=agree strongly.
