Collecting Self-report Data

• Self-report data usually are collected by an oral interview or written questionnaire.
• Open-ended questions permit respondents to reply in a narrative fashion, whereas closed-ended (or fixed alternative) questions offer response options from which respondents must choose.
• Another response bias is known as ac quiescence, which is a yea-sayer’s tendency to agree with statements regardless of their content. A converse problem arises when people (nay-sayers) disagree with most statements.
