An attitude scale is used to measure attitudes towards issues, institutions, or groups of people. It provides a quantitative measure on a continuum from extremely positive to extremely negative. The Likert scale and Thurstone technique are two common methods for indirectly measuring attitudes. The Likert scale uses statements rated on a 5-point agreement scale, while the Thurstone technique has judges sort statements into categories to determine scaled values. Attitude scales are useful but have limitations such as respondents potentially hiding their true attitudes or being unaware of them. Overall, attitude scales remain a valuable tool for measuring attitudes in social research.
