Determine the indicator’s value by using the following methodology:
1) List the messages that you want to assess. Select those messages that claim certain benefits of the behaviour in question, so that the respondent can say whether s/he agrees with them or not. For example, “Mothers! Breastmilk is the only food babies need during the first six months of life. It does not need any other food or fluids."
2) Set the minimum number of messages the respondent needs to see as trustworthy in order to meet the indicator (for example, at least 3 out of 5 messages).
3) Conduct individual interviews with a representative sample of the target group members:
RECOMMENDED SURVEY QUESTION (Q) AND POSSIBLE ANSWERS (A)
Q1: The message in [specify the communication material] says that [specify what the message claims]. To what extent do you believe that such information is or is not true?
A1: _
1) fully believes in what the message says
2) only partially believes in what the message says
3) does not believe in what the message says
4) does not know
4) Repeat the same question for all the other messages you want to assess.
5) Count the number of messages which the given respondent perceived as trustworthy - “fully believed” in what the message says.
6) To calculate the indicator’s value, divide the number of respondents who fully believed in at least the minimum number of messages by the total number of respondents (exclude those who did not know). Multiply the result by 100 to convert it to a percentage.
