Shyness Scale (SS)

Abstract

The Shyness Scale (SS), also referred to as the McCroskey Shyness Scale, is a 14-item self-report instrument designed to measure an individual’s actual communication behavior related to reduced talking. Developed by McCroskey and Richmond, this scale is unique in its deliberate distinction between shyness—defined strictly as reduced talking behavior—and related constructs such as Communication Apprehension (fear of communicating) or Willingness to Communicate (WTC, inclination to initiate communication).

The SS employs a 5-point Likert scale format and has demonstrated strong psychometric properties, including high internal consistency (alpha reliability estimates greater than 0.90) and high predictive validity distinct from other communication measures.

Purpose

The primary purpose of the Shyness Scale (SS) is to provide a precise, self-reported measure of an individual’s tendency toward reduced talking, which the authors define as the core behavioral manifestation of shyness. It serves to identify individuals who exhibit quiet or reserved communication patterns, specifically by quantifying the frequency of their verbal output.

The scale was developed to address limitations in earlier shyness measures in the field of Psychology that confounded behavioral components with affective or motivational components, thereby yielding uninterpretable scores. The SS offers a focused assessment of communication behavior only.

Construct

The psychological construct measured by the SS is shyness, operationalized strictly as the actual communication behavior of reduced talking. The developers emphasize that this construct must be kept separate from other related variables in communication research:

• Shyness (SS): Refers to the overt, observable behavior—the reduction in the quantity or frequency of verbal communication.

• Communication Apprehension (CA): Refers to the affective state—the fear, anxiety, or nervousness associated with anticipating or engaging in communication.

• Willingness to Communicate (WTC): Relates to the orientation—the predisposition or internal motivation to initiate communication when given the opportunity.

By focusing solely on reduced talking, the SS provides a clean measure of behavioral inhibition in social interaction.

Validity

The Shyness Scale demonstrates strong evidence of validity, particularly concerning its distinct measurement properties. It is reported to possess excellent face validity, as the items clearly relate to the observable behavior of talking or being quiet.

Research further confirms high predictive validity for the SS. This predictive power is shown to be independent of measures assessing Communication Apprehension (CA) or Willingness to Communicate (WTC). This independence confirms that the SS successfully predicts unique variance related to quiet communication behavior, confirming its success in measuring the intended construct without contamination from anxiety or motivation.

Reliability

The internal consistency of the Shyness Scale (SS) is reported to be outstanding. The measure has consistently generated high alpha reliability estimates, specifically stated as exceeding 0.90 (>.90).

An alpha coefficient above this threshold suggests that the 14 items comprising the scale are highly homogenous and measure the single underlying dimension of behavioral shyness with substantial consistency and precision across different administrations.

Factor Analysis

While the primary source material does not detail the results of formal factor analysis (e.g., specific factor loadings or variance explained), the reported high internal consistency (alpha reliability >.90) strongly implies that the 14 items load onto a single, robust factor consistent with the scale’s design as a unidimensional measure of reduced talking behavior.

Instrument

Test Type: Self-report questionnaire / Psychometric scale

Format: 14 items scored on a 5-point Likert-type scale.

Language Available: English (Original development language).

Population Group: General population; widely utilized in communication and educational research settings.

Age Group: Adolescents and Adults.

Population Details: Measures individual differences in overt communication behavior of reduced talking.

Test Methodology: Respondents rate 14 statements reflecting talking behavior using a scale ranging from Strongly Disagree = 1 to Strongly Agree = 5. The final score is calculated using a formula that accounts for both positively and negatively keyed items.

Items of the Shyness Scale (SS)

Directions: Below are fourteen statements that people sometimes make about themselves. Please indicate whether or not you believe each statement applies to you by marking whether you:

Strongly Disagree = 1; Disagree = 2; Neutral = 3; Agree = 4; Strongly Agree = 5

1. I am a shy person.
2. Other people think I talk a lot.
3. I am a very talkative person.
4. Other people think I am shy.
5. I talk a lot.
6. I tend to be very quiet in class.
7. I don’t talk much.
8. I talk more than most people.
9. I am a quiet person.
10. I talk more in a small group (3-6) than others do.
11. Most people talk more than I do.
12. Other people think I am very quiet.
13. I talk more in class than most people do.
14. Most people are more shy than I am.

Scoring:

Please score your responses as follows:

Step 1. Add the scores for items 1, 4, 6, 7, 9, 11, and 12.

Step 2. Add the scores for items 2, 3, 5, 8, 10, 13, and 14.

Step 3. Complete the following formula: Shyness = 42 plus Total of Step 1 minus Total of Step 2.

Your score should be between 14 and 70. Scores above 52 indicate a high level of shyness. Scores below 32 indicate a low level of shyness. Scores between 32 and 52 indicate a moderate level of shyness.
