Social Anxiety Questionnaire for Adults (SAQ-A30)

Abstract

The Social Anxiety Questionnaire for Adults—Short Form (SAQ-A30; Caballo et al., 2012) is a psychometric instrument comprising 30 items designed specifically for the assessment of social phobia (also known as Social Anxiety Disorder) across various social contexts. The SAQ-A30 represents a significant revision and shortening of the original 72-item Social Anxiety Questionnaire for Adults (SAQ-AR; Caballo et al., 2010). This revision was undertaken to ensure the inclusion of critical social situations that were either underrepresented or entirely absent in the longer, preceding version.

The development process began with an extensive initial pool of 512 items, which was systematically refined through expert consensus, resulting in a 118-item intermediate scale. Subsequent rigorous statistical reduction, utilizing both exploratory and confirmatory factor analyses, yielded the final 30-item scale. The SAQ-A30 is structured around five distinct dimensions of social anxiety: interactions with the opposite sex, public speaking/authority figures, assertive expression of negative emotions, interactions with strangers, and criticism/embarrassment. The scale exhibits strong internal consistency, reported at 0.93, and its validity has been partially demonstrated through convergent validity studies, although discriminant validity was not formally tested in the original validation research.

Purpose

The primary purpose of the Social Anxiety Questionnaire for Adults (SAQ-A30) is to provide a concise yet multidimensional measure of social anxiety in adult populations. The scale is specifically oriented towards assessing the severity of social phobia across a spectrum of challenging social situations.

Unlike some unidimensional measures, the SAQ-A30 is designed to capture the complexity and heterogeneity of social anxiety by dividing the construct into five distinct, clinically relevant subdomains. This allows clinicians and researchers to pinpoint specific areas where an individual experiences the highest levels of distress, thereby facilitating tailored treatment planning and refined diagnostic evaluation.

Construct

The psychological construct measured by the SAQ-A30 is Social Anxiety, encompassing the fear and avoidance of social situations due to concerns about being negatively judged, scrutinized, or humiliated by others. The scale views social anxiety not as a monolithic construct, but rather as a configuration of context-specific fears.

The resulting five-factor structure reinforces the multidimensional nature of social anxiety, moving beyond simple generalized fear to target specific interactional domains. These dimensions cover both performance-related fears (e.g., public speaking) and interactional fears (e.g., initiating conversations with strangers or the opposite sex), providing a detailed profile of an individual’s social phobic symptoms.

Validity

The validity of the SAQ-A30 was partially established during its development and validation phase in 2012. Specifically, the authors focused on demonstrating strong convergent validity, which indicates that the scale measures what it intends to measure by correlating highly with other established measures of the same construct.

Convergent validity was supported through significant positive correlation with the Liebowitz Social Anxiety Scale–Self-Report (LSAS-SR), a highly respected and widely used measure of social anxiety. This finding confirms that the SAQ-A30 effectively captures the core features of social anxiety consistent with other established instruments. However, the original validation study noted that discriminant validity—the extent to which the SAQ-A30 is distinct from measures of related but separate constructs (e.g., generalized anxiety or depression)—was not formally tested.

Reliability

The reliability of the SAQ-A30, specifically its internal consistency, was found to be exceptionally high. Internal consistency refers to the degree to which all items in a test measure the same underlying construct.

The reported Cronbach’s alpha coefficient for the total scale score is 0.93. This value is indicative of excellent reliability, suggesting that the 30 items are highly interrelated and consistently measure the overall severity of social anxiety. This high level of internal consistency enhances confidence in the stability and precision of the total score derived from the SAQ-A30.

Factor Analysis

The structure of the SAQ-A30 was determined through a rigorous, two-step statistical procedure involving both exploratory and confirmatory factor analyses. This process was crucial in reducing the initial large item pool (512 items) down to the final 30 items while ensuring the resulting scale maintained clear dimensional integrity.

The analyses identified and confirmed a structure consisting of five distinct factors or dimensions of social anxiety:

• Public Speaking/Authority Figures: Anxiety related to performance and interaction with superiors.
• Interactions with the Opposite Sex: Distress and avoidance in romantic or social situations involving the opposite gender.
• Assertive Expression of Negative Emotions: Difficulty or anxiety associated with expressing disagreement, annoyance, or setting boundaries.
• Interactions with Strangers: Fear related to initiating or maintaining conversations with unfamiliar people.
• Criticism/Embarrassment: Sensitivity and fear concerning negative evaluation or public humiliation.

Instrument

Test Type: Revision

Format: Self-Report Inventory/Questionnaire

Language Available: Spanish (Original development language, given the multinational sample), likely translated into Portuguese and other languages represented in the study cohort.

Population Group: Human (Male and Female)

Age Group: Adolescents (16+ years), Adults (18 years and older), Young Adults, Thirties, Middle Age, and Elderly (up to 68 years in the non-clinical sample).

Population Details: The scale was validated on a large, multinational sample encompassing both non-clinical subjects (ages 16–68) and mental health center patients (ages 16–66). The extensive geographical scope included participants from numerous Spanish- and Portuguese-speaking countries: Mexico, Colombia, Spain, Peru, Brazil, Chile, Bolivia, Portugal, Argentina, Uruguay, Venezuela, El Salvador, Guatemala, Honduras, Paraguay, and Ecuador. This multinational validation supports the scale’s multicultural applicability.

Test Methodology: The SAQ-A30 uses a Likert-type scale where respondents rate the level of unease, stress, or nervousness provoked by each social situation on a 5-point scale. The scale ranges from 1 (“Not at all”) to 5 (“Very High or Extremely High”). The instructions emphasize honest self-reporting regarding the emotional distress caused by the described situations.

Note on Control Items:

Items 10 (Being mugged or robbed by an armed gang) and 27 (One of my parents getting seriously ill) are designated as control items. These items are not included in the calculation of dimension scores or the total questionnaire score. They are used to check the validity of the respondent’s answers; a response of 1 or 2 on both of these items may suggest that the questionnaire was answered randomly or carelessly, as these are situations expected to provoke high distress in most individuals.
