In a method for providing a self-administered survey using a bar coded survey questionnaire having a plurality of survey questions and a plurality of selectable responses to the questions, with the selectable bar coded responses (10) being scannable for storing the selected responses (10); the improvement comprising providing a bar code scannable skip pattern prompt (12a, 12b) embedded in a scannable bar code pattern (10) also containing the selectable response (14a, 14b), the skip pattern prompt (12a, 12b) being dependent on the selected response (14a, 14b); selecting a response to a particular survey question by scanning (22) the bar code pattern (10) associated with the selected response (14a, 14b); storing the selected response (14a, 14b) based on the scanned bar code pattern (10) and displaying (24) a prompt message, indicating a next question to be answered in the survey questionnaire based on the same scanned bar code pattern (10), whereby a single scanning of the selected bar code pattern (10) provides both the response selected (14a, 14b) and the skip pattern (12a, 12b) to the next question to be answered for providing branching directly from the scanned response (10).
