Description

The State-Trait Anxiety Inventory for Children (STAIC-40) is a standardized psychological assessment tool designed to evaluate anxiety levels in children and adolescents aged 9–12 years.

The instrument distinguishes between two different forms of anxiety:

State Anxiety, which refers to anxiety experienced in response to specific situations or events and may change rapidly depending on circumstances.

Trait Anxiety, which represents a more stable and persistent tendency to experience anxiety across different situations.

The STAIC-40 provides a comprehensive assessment of children’s anxiety experiences by examining both temporary emotional states and more enduring anxiety tendencies.

Objective

The primary objective of the STAIC-40 is to provide a reliable and valid method for assessing anxiety levels in children and adolescents.

The scale aims to:

Assess situational anxiety responses.

Evaluate general anxiety proneness.

Support the identification of anxiety-related difficulties.

Assist in designing appropriate psychological interventions to support children’s mental health.

Structure and Content

The STAIC-40 consists of 40 items, divided into two subscales:

State Anxiety Scale, consisting of 20 items assessing current anxiety feelings related to immediate situations.

Trait Anxiety Scale, consisting of 20 items assessing general and relatively stable anxiety tendencies.

Items are rated using a Likert-type response format that evaluates the frequency or intensity of anxiety-related feelings.

Data Collection and Use

The STAIC-40 is completed by the child, with support from an adult such as a parent or teacher when necessary.

The items assess the frequency and intensity of anxiety-related emotions experienced by the child.

The collected data can be used for:

Assessment of anxiety symptoms.

Identification of children requiring psychological support.

Development of individualized intervention and coping strategies.

Monitoring changes in anxiety levels over time.

Scoring and Calibration

Each STAIC-40 item is rated using a Likert scale, typically ranging from:

1 = Not at all

to

3 = Very much.

State anxiety and trait anxiety scores are calculated separately by summing the responses of their respective items.

Higher scores indicate higher levels of anxiety.

Score interpretation involves comparing obtained scores with normative values for the relevant age group.

Statistical Analysis

Statistical analysis of STAIC-40 data may include:

Descriptive statistics, including means, standard deviations, and score distributions, to evaluate anxiety levels.

Reliability analysis using Cronbach’s alpha coefficient to assess internal consistency of the state and trait anxiety dimensions.

Comparisons with normative data to determine the relative severity of anxiety symptoms within age groups.

Correlation analyses with other psychological measures to examine relationships between anxiety and variables such as emotional adjustment, stress, and psychological functioning.

Comparative analyses to examine differences in anxiety levels according to age, gender, clinical characteristics, or environmental conditions.

Validity

The STAIC-40 has been validated through comparisons with other anxiety assessment scales and clinical evaluations.

Its validity is supported by its ability to differentiate between children with and without anxiety disorders.

Reliability

The reliability of the STAIC-40 is evaluated through internal consistency analysis using Cronbach’s alpha coefficient.

Reported reliability coefficients for both state and trait anxiety dimensions are typically high, indicating good internal consistency and measurement stability.

Applications

The STAIC-40 is widely used in:

Child and adolescent psychology.

Clinical assessment of anxiety disorders.

Educational psychology.

Research on emotional development and mental health.

Evaluation of psychological interventions aimed at reducing anxiety.
