The '''State-Trait Anxiety Inventory''' ('''STAI''') is a psychological inventory consisting of 40 self-report items on a 4-point [[Likert scale]]. The STAI measures two types of [[anxiety]] – state anxiety and trait anxiety. Higher scores are positively correlated with higher levels of anxiety. Its most current revision is Form Y and it is offered in more than 40 languages.<ref name="Tilton">{{cite journal |last1=Tilton |first1=S. R. |title=Review of the state-trait anxiety inventory (STAI) |journal=News Notes |volume=48 |issue=2 |year=2008 |pages=1–3 }}</ref> |
|||
The STAI was developed by psychologists [[Charles Spielberger]], R.L. Gorsuch, and R.E. Lushene. Their goal in creating the inventory was to create a set of questions that could be applied towards differentiating between the temporary condition of "state anxiety" and the more general and long-standing quality of "trait anxiety." This was a new development because all other questionnaires focused on one type of anxiety at the time.<ref>{{cite journal |vauthors=Heeren A, Bernstein EE, McNally RJ |title=Deconstructing trait anxiety: a network perspective |journal=Anxiety Stress Coping |year=2018| pmid = 29433339 |pages = 262–276 |volume = 31|issue = 3|doi = 10.1080/10615806.2018.1439263 |s2cid=4443186 |url=https://doi.org/10.1080/10615806.2018.1439263 }}</ref> |
|||
Spielberger also constructed other self-report state-trait scales purported to measure various other emotions and dispositions such as the State-Trait Anxiety Inventory for Children (STAI-CH), the State-Trait Curiosity Inventory (STCI), the State-Trait Anger Scale (STAS), the State-Trait Anger Expression Inventory (STAXI), and the State-Trait Personality Inventory (STPI). |
|||
Spielberger also created other self-report state-trait scales purported to measure various other emotions and dispositions. These include the State-Trait Anger Scale (STAS) and the State-Trait Anger Expression Inventory (STAXI). Alternate forms of the STAI have been developed, including a short-form version (STAI-6) as well as a child form, the State-Trait Anxiety Inventory for Children (STAIC).{{fact|date=December 2017}} |

The STAI requires a sixth grade reading level. It is used to aid diagnosis in clinical and other medical settings, including the [[differential diagnosis]] of anxiety and depression.<ref>{{cite journal |vauthors=Heeren A, Bernstein EE, McNally RJ |title=Deconstructing trait anxiety: a network perspective |journal=Anxiety Stress Coping |year=2018| pmid = 29433339 |pages = 262–276 |volume = 31|issue = 3|doi = 10.1080/10615806.2018.1439263 |s2cid=4443186 |url=https://doi.org/10.1080/10615806.2018.1439263 }}</ref> |

==State Anxiety (A-State)== |
|||
==History== |
|||
State anxiety (A-State) can be defined as fear, nervousness, discomfort, and the arousal of the [[autonomic nervous system]] induced temporarily by situations perceived as dangerous (i.e., how a person is feeling at the time of a perceived threat).<ref name="Sydeman" /> |
|||
[[Charles Spielberger]] was not alone in creating the STAI, R.L. Gorsuch, and R.E. Lushene also contributed to its development. It underwent revision to its current form in 1983.<ref>{{cite book |last1=Spielberger |first1=C.D. |last2=Gorssuch |first2=R.L. |last3=Lushene |first3=P.R. |last4=Vagg |first4=P.R. |last5=Jacobs |first5=G.A |year=1983 |title=Manual for the State-Trait Anxiety Inventory |publisher=Consulting Psychologists Press }}{{pn|date=December 2017}}</ref> It was developed as a method to assess two types of anxiety, state and trait, in the fields of practice and research. The inventory was developed in a way so that it could be one set of questions that when given the proper direction, could be applied towards the assessment of a specific type of anxiety. Some of the information used in the inventory was taken from other forms of measurement, and in the case of The Affect Adjective Check List (AACL), was even subject to the slight change of its current adjectives. After the inventory had been developed it underwent research to determine if it could be concluded as a valid source of assessment before it could be taken any further.<ref name="Sydeman">{{cite book |last1=Spielberger |first1=Charles D. |last2=Sydeman |first2=Sumner J. |year=1994 |chapter=State-Trait Anxiety Inventory and State-Trait Anger Expression Inventory |editor1-first=Mark Edward |editor1-last=Maruish |title=The use of psychological testing for treatment planning and outcome assessment |pages=292–321 |location=Hillsdale, NJ |publisher=Lawrence Erlbaum Associates |isbn=978-0-8058-1162-9 }}</ref> |

==The State-Trait Anxiety Inventory== |
|||
Examples: A child feels anxious when confronted by a large, strange animal. A person feels anxious to get on an airplane for the first time. |
|||
The State Trait Anxiety Inventory is a test/questionnaire given to adults that shows how strong a person’s feelings of anxiety are. It is offered and translated in twelve languages: English, Chinese, Danish, Dutch, Finnish, French, Italian, Norwegian, Portuguese, Spanish, Swedish, and Thai.<ref name="Verhoef">{{cite book |last1=Verhoef |first1=M. |last2=Ware |first2=M. |last3=Dryden |first3=T. |last4=Paterson |first4=C. |last5=Kania |first5=A. |year=2013 |title=State Trait Anxiety Inventory }}{{pn|date=December 2017}}</ref> It was developed to provide both short and reliable scales based on a person's answers to access state and trait anxiety.{{fact|date=December 2017}} |

==Trait Anxiety (A-Trait)== |
|||
Feelings of unease, worry, tension, and stress can be defined as [[anxiety]].<ref>{{cite book |last1=Nolen-Hoeksema |first1=S. |year=2011 |title=Abnormal psychology |edition=5th |page=522 |location=New York, NY |publisher=McGraw-Hill }}</ref> It is usually accompanied by a situation that causes these feelings for example, a big test or interview. Also, [[Prisoner|prisoners]] can experience such symptoms.'''<ref>{{Cite journal |last=Walters |first=G. D. |date=2022 |title=Separate Roles for State and Trait Anxiety in the Formation of SHU Syndrome: Testing a Moderated Mediation Hypothesis. |url=https://doi-org.library3.webster.edu/10.1177/00328855211069142 |journal=[[Prison Journal]] |volume=102 |issue=1 |pages=25–46}}</ref>''' It can also be caused by anxiety disorders such as Obsessive Compulsive Disorder (OCD) or Generalized Anxiety Disorder (GAD). The STAI tests two different types of anxiety, state and trait anxiety.{{fact|date=December 2017}} |
|||
Trait anxiety (A-Trait) can be defined as a relatively enduring disposition to feel stress, worry, and discomfort.<ref name="Sydeman" /> |
|||
State anxiety (S-anxiety) can be defined as fear, nervousness, discomfort, etc. and the arousal of the [[autonomic nervous system]] induced by different situations that are perceived as dangerous. This type of anxiety refers more to how a person is feeling at the time of a perceived threat and is considered temporary.<ref name="Sydeman" /> |
|||
Examples: A child experiences anxiety in social situations and is always anxiety prone throughout their childhood and adulthood. A person experiences anxiety in an array of normal situations such as going to the grocery store or going to work. |
|||
Trait anxiety (T-anxiety) can be defined as feelings of stress, worry, discomfort, etc. that one experiences on a day to day basis. This is usually perceived as how people feel across typical situations that everyone experiences on a daily basis.<ref>{{cite journal |vauthors=Heeren A, Bernstein EE, McNally RJ |title=Deconstructing trait anxiety: a network perspective |journal=Anxiety Stress Coping |year=2018| pmid = 29433339 |pages = 262–276 |volume = 31|issue = 3|doi = 10.1080/10615806.2018.1439263 |s2cid=4443186 |url=https://doi.org/10.1080/10615806.2018.1439263 }}</ref> |

==Forms== |
==Forms== |
||
This inventory is made up of 40 questions, and distinguishes between a person’s state anxiety and their trait anxiety. The two forms of anxiety are separated in the inventory, and both are given their own 20 separate questions. When participants rate themselves on these questions, they are given a 4-point frequency scale. The frequency scales differ between the two types of anxiety. There are two main forms of the Inventory, Form X and Form Y.<ref name="Sydeman" /> |
|||
Form X of the STAI was revised from the original STAI to develop a better way of measuring both state and trait anxieties. This was done in order to better differentiate between patients suffering from anxiety and depressive disorders when being diagnosed. By revising the STAI, many questions from the original inventory were replaced.<ref name="Sydeman" /> |
|||
===State-Trait Anxiety Inventory (Form X)=== |
|||
The original Form X of the STAI was revised resulting in Form Y.<ref name="Sydeman" /> |
|||
Form Y of the STAI was constructed by replacing items from Form X. By doing so, Form Y in turn has better defined state and trait anxiety factors. The major difference between Form X and Form Y is that Form Y has a better simple structure, as well as the anxiety factors being better differentiated and stable than Form X. This form of the STAI is currently being used more often than the original Form X.<ref name="Sydeman" /> |
|||
===State-Trait Anxiety Inventory (Form Y)=== |
|||
Form Y of the STAI is a more popular version with improved psychometric properties.<ref name="Sydeman" /> |
|||
==Scoring== |
==Scoring== |
||
The State-Trait Anxiety Inventory is one of the first tests to assess both state and trait anxiety separately. Each type of anxiety has its own scale of 20 different questions that are scored.<ref name="Gros">{{cite journal |doi=10.1037/1040-3590.19.4.369 |pmid=18085930 |title=Psychometric properties of the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA): Comparison to the State-Trait Anxiety Inventory (STAI) |journal=Psychological Assessment |volume=19 |issue=4 |pages=369–81 |year=2007 |last1=Grös |first1=Daniel F |last2=Antony |first2=Martin M |last3=Simms |first3=Leonard J |last4=McCabe |first4=Randi E }}</ref> Scores range from 20 to 80, with higher scores correlating with greater anxiety. The creators of this test separated the different anxieties so both scales would be reliable. This means the S-anxiety scale would only measure S-anxiety and the T-anxiety scale would only measure T-anxiety, the ultimate goal in creating this test. They found they could not achieve this if the questions were the same to examine both types of anxiety. Each scale asks twenty questions each and are rated on a 4-point scale.<ref name="Gros" /> Low scores indicate a mild form of anxiety and high scores indicate a severe form of anxiety. Both scales have anxiety absent and anxiety present questions. Anxiety absent questions represent the absence of anxiety in a statement like, “I feel secure.” Anxiety present questions represent the presence of anxiety in a statement like “I feel worried.” More examples from the STAI on anxiety absent and present questions are listed below. Each measure has a different rating scale. The 4-point scale for S-anxiety is as follows: 1.) not at all, 2.) somewhat, 3.) moderately so, 4.) very much so. The 4-point scale for T-anxiety is as follows: 1.) almost never, 2.) sometimes, 3.) often, 4.) almost always.<ref name="Sydeman" /> |
|||
==Uses== |
|||
The 4-point A-State intensity response scale is as follows: |
|||
# not at all |
|||
# somewhat |
|||
# moderately so |
|||
# very much so. |
|||
The various State-Trait tests each evaluate different emotions. The State-Trait Anxiety Inventory measures anxiety by assessing someone’s state and trait anxiety. The STAI was one of the first tests to examine state and trait anxiety at the same time. There are two forms of the STAI, one for children, and for adults. The scale is useful for many different socio-economic backgrounds and groups and anyone that has the equivalence of a sixth grade reading level, it therefore can be utilized for many people. Clinicians use this in diagnosing patients in a clinical setting. It is also used to diagnose clinical anxiety in surgical and other medical patients as well as in mental health patients. The STAI, itself, assesses anxiety but also can be used to make a discrimination when wondering whether a patient is experiencing anxiety or depression. This inventory is used in research projects. Various journal articles have used the STAI in conducting research and comparing different ethnic groups, age groups, etc. regarding anxiety. <ref name="CD">{{cite book |last1=Spielberger |first1=C.

|||
There is also a State Trait Anxiety Inventory for children, or the STAIC. The STAIC distinguishes between how prone a child is to anxious behavior and emotional anxiety. It is very similar to the STAI, and is based on the same concept as the adult measure. This measure is used for children between the ages of 9–12. It includes two sets of 20 questions, 20 questions for A-State anxiety and 20 questions for A-Trait anxiety, that is easily read, and if needed can be verbally read to younger children.<ref name="CD" /> |
|||
Spielberger also developed a few other scales, the State-Trait Anger Scale, the State-Trait Personality Inventory, and the State-Trait Anger Expression Inventory.<ref name="Verhoef" /> |
|||
===State-Anxiety=== |
|||
* "I feel at ease." |
|||
* "I feel upset." |
|||
===Trait-Anxiety=== |
|||
* "I lack self-confidence." |
|||
* "I am a steady person." |
|||
==Additional Scales== |
|||
The STAIC (a downward extension of the STAI) can be administered to children up to junior high school level (aged 9–12 years). If necessary, the items can be verbally read out to younger children.<ref name="CD" /> Spielberger also constructed other self-report scales, including the State-Trait Anger Scale (STAS) and its short-form (STAS-6), the State-Trait Anger Expression Inventory (STAXI), and the State-Trait Personality Inventory (STPI),<ref name="Verhoef" /> |
|||
===State-Trait Anger Scale (STAS)=== |
===State-Trait Anger Scale (STAS)=== |
||
[[Anger]] is an emotional state when feelings can vary in intensity, from irritation, to annoyance, to the extremes of fury or rage. This differs from [[hostility]] and [[aggression]] in that anger is much less complex than hostility or aggression, while both of these states can include feelings of anger.<ref name="Sydeman" /> |

The STAS is very similar in format to the STAI. However, this scale was formed instead to measure anger as an emotional state and how prone to anger people are. |

||
This scale measures both state and trait anger, it is similar to the STAI in assessing state and trait emotions. State anger (S-Anger) is a psychobiological state or condition. This state consists of varying intensities of anger. It is assumed that S-Anger would change over time, based on the situations of the person. Trait anger (T-Anger) is defined by the [[individual differences]] in how often that S-Anger was experienced over time. |
|||
===State-Trait Anger Expression Inventory (STAXI-2)=== |
|||
The STAXI-2 (revised 2nd edition) purports to measure an individual's experience, expression, and control of anger. The STAXI-2 includes self-report scales purported to measure State Anger, Trait Anger, Anger Expression-Out, Anger Expression-In, Anger Control-Out, Anger Control-In, and Anger Expression Index. Ratings are on a 4-point forced-choice response scale. The State Anger scale measures transient anger intensity, while the Trait Anger scale measures the frequency of angry feelings. The Anger Expression-In scale measures the extent to which one “holds things in” or suppresses anger, whereas the Anger Expression-Out scale measures the actual expression of aggression. The Anger Control-In scale measures the extent to which the suppression of anger is controlled, whereas the Anger Control-Out scale measures the constraint of overt anger expression. Even when the overt expression of anger (Anger-out) is minimal, the STAXI-2 can capture anger that may be present where Anger-in scores are high. A person’s handling of anger may lie between overcontrol and undercontrol which the STAXI-2 can help identify. |
|||
The STAXI-2 comprises 57 items, which make up 7 separate scales as follows:<ref name="Sydeman" /> |
|||
# S-Anger: 15 items |
|||
# T-Anger: 10 items |
|||
# AX/In: 8 items; Measures how often feelings of anger are experienced and are held in and not acted on. |
|||
# AX/Out: 8 items; Measures how often feelings of anger are acted upon towards people or objects. |
|||
# ACon/In: 8 items; Measures how often an individual tries to control of suppressed anger. |
|||
# ACon/Out: 8 items; Measures how often an individual tries to control the outward expression of anger. |
|||
# AX: 24 items; Measures how often anger is generally being experienced and expressed. |
|||
Psychometric Properties: |
|||
Item Homogeneity: Based on the STAXI-2 normative sample (N > 1,900), a median Cronbach alpha coefficient of .87 for the STAXI-2 has been reported, with alphas for the AX index ranging from .75 to .82.<ref>Spielberger, C. D., & Reheiser, E. C. (2004). Measuring anxiety, anger, depression, and curiosity as emotional states and personality traits with the STAI, STAXI, and STPI. In M. Hersen, D.L. Segal, & M. Hilsenroth (Eds.), ''Comprehensive Handbook of Psychological Assessment (Vol. 2): Personality Assessment'' (pp. 74-80). New York: Wiley.</ref> High alpha coefficients however may be indicative of a narrow scale with little breadth of measurement of the relevant construct/factor.<ref>{{cite journal | last1 = Boyle | first1 = G.

|||
Reliability: Over a two-month interval, test-retest (stability) coefficients for a French adaptation of the STAXI-2 (N = 139) were found to be .70 for the trait anger scale and .32 for the state anger scale, respectively (in accord with state-trait theory).<ref name="Borteyrou">{{cite journal | last1 = Borteyrou | first1 = X. | last2 = Bruchon-Schweitzer | first2 = M. | last3 = Spielberger | first3 = C.

==State-Trait Personality Inventory (STPI)== |

'''Variable''' |

The STPI is useful for measuring the four affects of anxiety, depression, anger and curiosity. The STPI measures these constructs both as traits/dispositions and as transitory emotions/states.<ref>Spielberger, C. D. et al. (1995).

'''Description''' |
|||
The 80-item STPI includes 10 items for each of eight state-trait scales. The STPI was derived from the State-Trait Anxiety Inventory (STAI),<ref name="Spielberger, C. D., Gorsuch, R. L." /> and the State-Trait Anger Expression Inventory (STAXI).<ref>Spielberger, C. D. (1999). ''Professional Manual for the State-Trait Anger Expression Inventory-2'' (STAXI-2). Odessa, FL: Psychological Assessment Resources.</ref> For state items, instructions are to respond as to one’s present feelings "at this very moment" on a 4-point response scale. For trait items, instructions are to respond as to how one generally feels. As with the single-dimension scales (STCI, STAI, STAS, STDI), the STPI items are mainly adjective ratings. |

'''Test-Retest Reliability''' |

Stability coefficients for the A-Trait scale were found to range from .73 to .86 across 3-15 week intervals, whereas the median stability coefficient for the A-State scale was .33 as would be expected for a situationally sensitive measure.<ref name="Spielberger, C. D., & Reheiser, E. C." /> Thus, two-week stability coefficients for the state anger scale were .27 (males) and .21 (females), while for the trait anger scale .70 (males) and .77 (females).<ref>{{cite journal | last1 = Jacobs | first1 = G.

This scale measures both state and trait anger, it is similar to the STAI in assessing state and trait emotions. State anger (S-Anger) is a psychobiological state or condition. This state consists of varying intensities of anger. It is assumed that S-Anger would change over time, based on the situations of the person. Trait anger (T-Anger) is defined by the [[individual differences]] in how often that S-Anger was experienced over time.<ref>{{Cite web |last=Spielberger |first=Charles |date=1988 |title=State-Trait Anger Expression Inventory |url=http://dx.doi.org/10.1037/t29496-000 |access-date=2023-07-12 |website=PsycTESTS Dataset}}</ref> |

For example, the trait depression scale exhibited an overall median correlation of .78 with the Beck Depression Inventory (BDI), the Zung Self-Rating Depression Scale (ZUNG), and the Center for Epidemiological Studies Depression Scale (CES-D)—(for a psychometric review of these scales, see Boyle<ref>{{cite journal | last1 = Boyle | first1 = G.

The corresponding median correlation with the state depression scale was .66. Spielberger and Reheiser also found that the A-trait scale correlated .73 with the Taylor Manifest Anxiety Scale (TMAS), and .85 with the Cattell Anxiety Scale Questionnaire (ASQ).<ref>Cattell, R.

The STAXI provides objective and shortly scored measures of a person’s experience, expression, and control of anger. It consists of 44 items, which make up 7 scales.<ref name="Sydeman" /> These scales measures six components of anger: |

State-Trait Anxiety Inventory | |
---|---|
Purpose | measures 2 types of anxiety |
The State-Trait Anxiety Inventory (STAI) is a psychological inventory consisting of 40 self-report items on a 4-point Likert scale. The STAI measures two types of anxiety – state anxiety and trait anxiety. Higher scores are positively correlated with higher levels of anxiety. Its most current revision is Form Y and it is offered in more than 40 languages.[1]
The STAI was developed by psychologists Charles Spielberger, R.L. Gorsuch, and R.E. Lushene. Their goal in creating the inventory was to create a set of questions that could be applied towards differentiating between the temporary condition of "state anxiety" and the more general and long-standing quality of "trait anxiety." This was a new development because all other questionnaires focused on one type of anxiety at the time.[2]
Spielberger also created other self-report state-trait scales purported to measure various other emotions and dispositions. These include the State-Trait Anger Scale (STAS) and the State-Trait Anger Expression Inventory (STAXI). Alternate forms of the STAI have been developed, including a short-form version (STAI-6) as well as a child form, the State-Trait Anxiety Inventory for Children (STAIC).[citation needed]
The STAI requires a sixth grade reading level. It is used to aid diagnosis in clinical and other medical settings, including the differential diagnosis of anxiety and depression.[3]
History
[edit]Charles Spielberger was not alone in creating the STAI, R.L. Gorsuch, and R.E. Lushene also contributed to its development. It underwent revision to its current form in 1983.[4] It was developed as a method to assess two types of anxiety, state and trait, in the fields of practice and research. The inventory was developed in a way so that it could be one set of questions that when given the proper direction, could be applied towards the assessment of a specific type of anxiety. Some of the information used in the inventory was taken from other forms of measurement, and in the case of The Affect Adjective Check List (AACL), was even subject to the slight change of its current adjectives. After the inventory had been developed it underwent research to determine if it could be concluded as a valid source of assessment before it could be taken any further.[5]
The State-Trait Anxiety Inventory
[edit]The State Trait Anxiety Inventory is a test/questionnaire given to adults that shows how strong a person’s feelings of anxiety are. It is offered and translated in twelve languages: English, Chinese, Danish, Dutch, Finnish, French, Italian, Norwegian, Portuguese, Spanish, Swedish, and Thai.[6] It was developed to provide both short and reliable scales based on a person's answers to access state and trait anxiety.[citation needed]
Feelings of unease, worry, tension, and stress can be defined as anxiety.[7] It is usually accompanied by a situation that causes these feelings for example, a big test or interview. Also, prisoners can experience such symptoms.[8] It can also be caused by anxiety disorders such as Obsessive Compulsive Disorder (OCD) or Generalized Anxiety Disorder (GAD). The STAI tests two different types of anxiety, state and trait anxiety.[citation needed]
State anxiety (S-anxiety) can be defined as fear, nervousness, discomfort, etc. and the arousal of the autonomic nervous system induced by different situations that are perceived as dangerous. This type of anxiety refers more to how a person is feeling at the time of a perceived threat and is considered temporary.[5]
Trait anxiety (T-anxiety) can be defined as feelings of stress, worry, discomfort, etc. that one experiences on a day to day basis. This is usually perceived as how people feel across typical situations that everyone experiences on a daily basis.[9]
Forms
[edit]This inventory is made up of 40 questions, and distinguishes between a person’s state anxiety and their trait anxiety. The two forms of anxiety are separated in the inventory, and both are given their own 20 separate questions. When participants rate themselves on these questions, they are given a 4-point frequency scale. The frequency scales differ between the two types of anxiety. There are two main forms of the Inventory, Form X and Form Y.[5]
Form X of the STAI was revised from the original STAI to develop a better way of measuring both state and trait anxieties. This was done in order to better differentiate between patients suffering from anxiety and depressive disorders when being diagnosed. By revising the STAI, many questions from the original inventory were replaced.[5]
Form Y of the STAI was constructed by replacing items from Form X. By doing so, Form Y in turn has better defined state and trait anxiety factors. The major difference between Form X and Form Y is that Form Y has a better simple structure, as well as the anxiety factors being better differentiated and stable than Form X. This form of the STAI is currently being used more often than the original Form X.[5]
Scoring
[edit]The State-Trait Anxiety Inventory is one of the first tests to assess both state and trait anxiety separately. Each type of anxiety has its own scale of 20 different questions that are scored.[10] Scores range from 20 to 80, with higher scores correlating with greater anxiety. The creators of this test separated the different anxieties so both scales would be reliable. This means the S-anxiety scale would only measure S-anxiety and the T-anxiety scale would only measure T-anxiety, the ultimate goal in creating this test. They found they could not achieve this if the questions were the same to examine both types of anxiety. Each scale asks twenty questions each and are rated on a 4-point scale.[10] Low scores indicate a mild form of anxiety and high scores indicate a severe form of anxiety. Both scales have anxiety absent and anxiety present questions. Anxiety absent questions represent the absence of anxiety in a statement like, “I feel secure.” Anxiety present questions represent the presence of anxiety in a statement like “I feel worried.” More examples from the STAI on anxiety absent and present questions are listed below. Each measure has a different rating scale. The 4-point scale for S-anxiety is as follows: 1.) not at all, 2.) somewhat, 3.) moderately so, 4.) very much so. The 4-point scale for T-anxiety is as follows: 1.) almost never, 2.) sometimes, 3.) often, 4.) almost always.[5]
Uses
[edit]The various State-Trait tests each evaluate different emotions. The State-Trait Anxiety Inventory measures anxiety by assessing someone’s state and trait anxiety. The STAI was one of the first tests to examine state and trait anxiety at the same time. There are two forms of the STAI, one for children, and for adults. The scale is useful for many different socio-economic backgrounds and groups and anyone that has the equivalence of a sixth grade reading level, it therefore can be utilized for many people. Clinicians use this in diagnosing patients in a clinical setting. It is also used to diagnose clinical anxiety in surgical and other medical patients as well as in mental health patients. The STAI, itself, assesses anxiety but also can be used to make a discrimination when wondering whether a patient is experiencing anxiety or depression. This inventory is used in research projects. Various journal articles have used the STAI in conducting research and comparing different ethnic groups, age groups, etc. regarding anxiety. [11]
Additional scales
[edit]There is also a State Trait Anxiety Inventory for children, or the STAIC. The STAIC distinguishes between how prone a child is to anxious behavior and emotional anxiety. It is very similar to the STAI, and is based on the same concept as the adult measure. This measure is used for children between the ages of 9–12. It includes two sets of 20 questions, 20 questions for A-State anxiety and 20 questions for A-Trait anxiety, that is easily read, and if needed can be verbally read to younger children.[11] Spielberger also developed a few other scales, the State-Trait Anger Scale, the State-Trait Personality Inventory, and the State-Trait Anger Expression Inventory.[6]
State-Trait Anger Scale (STAS)
[edit]Anger is an emotional state when feelings can vary in intensity, from irritation, to annoyance, to the extremes of fury or rage. This differs from hostility and aggression in that anger is much less complex than hostility or aggression, while both of these states can include feelings of anger.[5]
The STAS is very similar in format to the STAI. However, this scale was formed instead to measure anger as an emotional state and how prone to anger people are.[12]
This scale measures both state and trait anger, it is similar to the STAI in assessing state and trait emotions. State anger (S-Anger) is a psychobiological state or condition. This state consists of varying intensities of anger. It is assumed that S-Anger would change over time, based on the situations of the person. Trait anger (T-Anger) is defined by the individual differences in how often that S-Anger was experienced over time.[13]
State-Trait Anger Expression Inventory (STAXI)
[edit]The STAXI provides objective and shortly scored measures of a person’s experience, expression, and control of anger. It consists of 44 items, which make up 7 scales.[5] These scales measures six components of anger:
- S-Anger: 10 questions
- T-Anger: 10 questions
- AX/In: 8 questions; This measures individual differences in how often feelings of anger are experienced and are held in and not acted on.
- AX/Out: 8 questions; This measures individual differences in how often feelings of anger are acted upon towards people or objects.
- AX/Con: 8 questions; This measures individual differences in how often a person tries to control their outward expression of anger.
- AX/Ex: 24 questions; This provides a general view of how often anger is being experienced and expressed.
Six-item State-Trait Anxiety Inventory (STAI-6)
[edit]There is a short-form version of the state scale, consisting of six items chosen for reliability and validity. It is designed to be administered in circumstances that prohibit the use of the full-form, and produces scores that are comparable to using the full version.[14]
