The Revised Cheek and Buss Shyness Scale


In the early 1980s, there was a growing interest in understanding personality traits related to social behavior, and shyness was one such trait that garnered attention. Shyness is a complex personality characteristic involving feelings of apprehension and tension during social situations. Researchers aimed to develop a reliable and valid measure to assess shyness, which led to the creation of the Cheek and Buss Shyness Scale.

In their introduction, Cheek and Buss highlighted the lack of a standardized and widely accepted measure for assessing shyness at the time. They emphasized the need for a tool that could capture the multifaceted nature of shyness, encompassing both social discomfort and a desire for social interaction.

The Cheek and Buss Shyness Scale was designed to measure shyness along two main dimensions: social discomfort and social avoidance. Social discomfort refers to feelings of anxiety or unease in social situations, while social avoidance involves behaviors aimed at minimizing or escaping social interactions.

The scale was created through a process of item selection and validation, involving the assessment of its reliability and validity across different samples. It consists of self-report items that individuals respond to based on their experiences and feelings in social situations.

Administration, Scoring and Interpretation

  • Provide participants with a copy of the RCBS questionnaire.
  • Ask participants to read each item carefully and decide to what extent it is characteristic of their feelings and behavior.
  • Ask participants to fill in the blank next to each item by choosing a number from the scale printed below.
  • Remind participants that there are no right or wrong answers, and that they should answer honestly.

Reliability and Validity

The Revised Cheek and Buss Shyness Scale (RCBS) is a widely used measure of shyness that has been shown to have good psychometric properties.

The RCBS has high internal consistency, meaning that the items on the scale are all measuring the same construct (shyness). The Cronbach’s alpha coefficient for the RCBS is typically around .85, which is considered to be excellent.

The RCBS also has good test-retest reliability, meaning that scores on the scale are stable over time. The correlation between RCBS scores obtained at two different points in time is typically around .70, which is considered to be good.

The RCBS has been shown to have good convergent validity, meaning that it correlates with other measures of shyness and social anxiety. For example, the RCBS correlates with the Liebowitz Social Anxiety Scale (LSAS) at .60, and with the Social Interaction Anxiety Scale (SIAS) at .50.

The RCBS has also been shown to have good discriminant validity, meaning that it does not correlate too highly with measures of other constructs, such as neuroticism and extraversion. For example, the RCBS correlates with neuroticism at .30, and with extraversion at -.40.
