Table 2.

Bivariate polychoric correlations with an intention to receive influenza vaccine.

Table of influenza vaccine survey items by code with polychoric correlation coefficients. The table lists 19 items with polychoric correlation values, indicating the strength of association between questions about the influenza vaccine and respondents′ attitudes or behaviors. The correlations range from 0.86 to 0.33. The highest correlation (0.86) is for the question about the responsibility to get vaccinated to protect others (SP1). The second highest (0.84) concerns the importance of the vaccine for personal health (TF6). Other notable correlations include family and friends′ influence (0.80, SP3), perceived protection from the vaccine (0.78, TF4) and community protection (0.73, TF5). Trust in health workers (0.66, TF8) and recommendations from health workers (0.60, SP6) also show significant correlations. Lower correlations are seen with questions about ease of access and affordability (0.45, P5; 0.41, P6; 0.39, P7) and awareness of the vaccine (0.51, TF3). The lowest correlation (0.33) is related to perceived severity of influenza (TF2).
