Final answer:
To identify response sets in a Likert scale, reverse scoring pre-coded answers and using a validity scale like the Lie Scale is effective in detecting if respondents are presenting themselves in a socially desirable light.
Step-by-step explanation:
In order to identify response sets in a Likert scale, the best approach would be to reverse the scoring of pre-coded answers. This technique is often employed in psychological assessments and helps to identify patterns of answers that suggest a respondent may be trying to present themselves in a socially desirable light rather than answering honestly. For example, if a Likert scale included statements with both positive and negative connotations about a topic, and a respondent consistently chose the most positive option, reversing the scoring of some items can help reveal if they are 'faking good'. Including a validity scale, such as the Lie Scale, in a self-report inventory is another method used to detect if respondents are presenting themselves unrealistically in a positive light. It is not enough to rely on participants following instructions not to deceive, nor should the survey only include items about socially desirable behaviors, as this could skew the results.
