PSYC 4030 Lecture Notes - Lecture 6: Social Desirability Bias, Standard Deviation
Document Summary
Questionnaire data: allows us to compare a client to others of the same age/gender, never formulate based on a questionnaire alone because it does not give us context. Social desirability bias; where the client tries to answer the question the way they think you want them to. Social debasement bias, where the client tries to answer the wrong way. Never give a diagnosis based on questionnaire data because people are susceptible to social desirability or social debasement. Convert responses to t-scores so we can compare them. The population mean is always 50; =50 is average. The standard deviation is always 10; t-scores are always positive. Look at the sd; almost everyone falls within +/- 3 sd from the mean. If t is less than or equal to 64, this is the average range. If t is 65-69, inclusive, this is the borderline (top 7% of gender/age group).
