Section 2: Instrument Description
a) Instrument Function: What does it measure?
BAI is a tool used to measure the level of anxiety in persons aged 18 and above. It is the criteria referenced assessment instrument. The Beck Anxiety Inventory provides professionals with a strong basis on which to anchor their diagnosis and decisions about the same (Beck et al., 1988; Beck & Steer, 1993). The instrument can be used to measure baseline anxiety to establish how effective treatment is as it goes on. It can also be applied as an outcome measure during the post-treatment period.
(a) Population: Who does the instrument target?
Adults and adolescents- to measure their anxiety levels
(b) How is the instrument used and scored?
The instrument can be used verbally by a trained expert or administered by self and cored by hand
(c) What type of scores does the instrument produce?
The instrument uses a manual scoring or Q-global scoring approach. Q-global is an internet-based site for administration of tests, scoring them, and reporting. It is the home of the industry’s universal standard for assessment. It can be accessed by all internet users. Q-global is fast and efficient in organizing information for examinees, generation of scores, and production of reports that are accurate and comprehensive. The scores range from 0 to 63 and are classified as minimal anxiety, mild anxiety, moderate and severe with scores of 0-7, 8-15, 16-25, and 30-63 respectively (Beck et al., 1988; Gillis, Haaga & Ford, 1995; Halfaker et al., 2011). Generally, the scores are generated from the raw score, although T-scores also exist along with percentiles informed by Psych Corp’s sample of community adults.
Section 3: Psychometric Properties
Describe the norm group. Explain if it is representative, current, and large enough? Explain if the instrument is appropriate for multicultural populations?
The respondents are requested to report how much they have been bothered during the week by each of the 21 symptoms before the BAI testing completion, including the day of completion. Each of the symptoms is provided with four answer options considered to be all possible, i.e., Not at all= 0; mild moderately=2, severely=3(Beck et al., 1988). The scoring formula is a simple process for anyone with the knowledge of the English language, even at the basic level. Furthermore, the tool has attracted validation in various languages across the globe, including Chinese, German, Icelandic, Spanish, French, among others (Oh et al., 2018). The tool is a reliable discriminating tool for anxious and non-anxious people. Therefore, it is widely used as a screening tool for anxiety in a wide range of clinical environments. Thus, it would be accurate to say that it is used by multicultural communities.
Describe the reliability evidence of test results (test-rest, alternate forms, internal consistency, inter-rater reliability). Is there enough reliability evidence to make a decision whether to use or not to use the instrument?
Eighty-three patients drawn from a group that had completed their BAI indicated an average item correlation of .60 Beck & Steer, 1993; Biggs, 2008). The internal consistency using Cronbach’s alpha stretches from .92 to -94 for adults test, and the re-test reliability is .75. The BAI has demonstrated acceptable reliability. It also shows discriminant and convergent validity for people aged 14 to 18 years in inpatient setups and outpatient (Beck et al., 1988; Gillis et al., 1995). Therefore, the BAI is psychometrically sound to warrant usage.
Describe the validity evidence of test results (content, criterion-related, construct). Is there enough validity evidence to make a decision whether to use or not to use the instrument?
The concurrent validity compared with the Hamilton Anxiety Rating is .51; .58 for state and .47 in Trait subscales of State-Trait Anxiety Inventory (STAI) form Y. It reads 54 for the seven days mean anxiety rating of the weekly record of anxiety and depression (Beck et al., 1988; Beck & Steer, 1993). Thus, yes, the scale provides sufficient validity to inform a decision to use it.
Describe and summarize at least two different professional reviews of the test, i.e., Mental Measurement Yearbook, Tests in Print, or other sources.
A review of survey-based test usage research in the 90s shows that the BAI was not highly ranked for measuring anxiety at the onset. Now, an existing literature review on how popular the BAI in psychology training or settings of practice has not been analyzed systematically. However, Piontrowsky and Gallant pointed out that BAI is the most visible scale for anxiety in the literature of research between 2000 and 2005. Still, the area of clinical assessment is widely competitive with many mental health scales emerging in both the research and professional literature. Furthermore, as from the middle of the 90s, regulatory restrictions on the use of multi-method assessment have been a barrier in practice. Historically, therefore, the acceptance of BAI professionally has remained unclear about the extent of usage in training and clinical setups, relative to other instruments in use.
The current study seeks to address the gap in the literature available. Thus, the author was identified via an in-depth literature review, studies using the survey method relating to the assessment of personality, which have been documented on graduate training in testing in psychology and the usage patterns of the test starting from 1989 to 2017. The systematic search produced 45 articles that included a dissertation study. This was used for this review. The findings indicate that the BAI has been utilized and relied on moderately, at least in 21 out of the 35 practice settings survey and in seven out of the ten academic internship studies. While the BAI tool has neither been common nor popular as other tests, such as the BDI, this review indicates that as from 2010, the BAI has begun to gain traction with professional usage, generates notable excitement in assessment training circles, and is adopted by clinical faculties.
The present review, while reflecting the level of usage of the BAI, indicates that 10 of the 14 studies from 2010 onwards reported that the BAI a. is recognized and depended on highly in practice and assessment training, b. a valued tool for clinicians of mental health practice and c. regarded s the choice instrument among a wide range of setups and professional users for self-reporting measures in assessing disorders of mood. Other factors, such as likely competitors, including new measures or already established ones that may affect the trends in the future relating to the use of the BAI, were discussed. Also, there should research effort directed at investigating the common the negative affectivity common factor portrayed in the BAI when distinguishing anxiety from depression in tracing outcomes of treatment (Piotrowski, 2018).
The creation and development of a self-report inventory of 21 items for gauging anxiety severity in psychiatric subjects, according to Beck et al. (1988), is defined. The first pool consisting of 86 items was drawn from scales that were already in existence: the checklist of anxiety, the desk reference checklist of the physician, and the anxiety born out of the situation checklist. Several analyses were used to reduce the pool of items. The outcome, the BAI is a scale of 21 items that indicated high consistency internally (??=?.92), and reliability of test-retest over a week, r(81)= .75. The tool discriminated against anxiety among the diagnostic groups from those that were not anxious. Furthermore, the BAI underwent correlation, moderately, with the revised Hamilton anxiety rating scale, i.e., r(150)=.51, and was slightly correlated with the revised Hamilton Depression Rating Scale of r(153)=.25
In their review, Leyfer, Ruberg & Woodruff-Borden (2006) administered the BAI and the Anxiety Disorders Interview Schedule (ADIS-IV) to 193 adult subjects at a Midwestern university drawn from a research and treatment center for anxiety. They compared the BAIs scores of four factors from persons with a basic diagnosis of generalized anxiety disorder, social or specific phobia, panic syndrome with or without agoraphobia, OCD, and without a psychiatric diagnosis. The BAI and factor cut scores, specificity, sensitivity, including the negative and predictive values were computed for each of the groups. The results in the study concur with earlier findings that the strongest aspect of the BAI is its effectiveness in assessing anxiety symptoms. This review expounds the notion by emphasizing that BAI can and should be used as an effective and efficient screening tool for anxiety disorder.
Section 4: Practical Aspects
How much time is required to administer the instrument?
5 - 10 minutes
How easy or difficult is it to administer, score, and interpret the instrument?
The BAI is a scale with 21 items designed to measure the severity of anxiety (Beck et al., 1988; Beck & Steer, 1993. The respondents are required to rate items based on a scale of four starting from 0, which indicates no anxiety to 3, which indicates severe anxiety. The ratings are drawn from items collected in the past week, and the items are added up to arrive at the full scores starting from 0 to 3(Beck & Steer, 1993). Thus, it is concluded that scoring and administering the tool is as simple as it gets, but the interpretation of outcomes might be a bit hard. By rereading the manual, each user can interpret the outcomes. Nevertheless, it is preferred that the interpretation should be made by an expert.
What is the cost of the instrument (including manuals, test booklets, answer sheets, computer administration, and scoring, etc.)?
The BAI is found in 3 packages. They include 1. Q-Local Software scoring and Reporting, 2. Q-global, Web-Based Administration, Scoring and Reporting, and 3. Manual Scoring Their prices range as provided in the table below.

How useful is the instrument manual?
Since the tool can be used easily, the manual is just as easy to follow. Nevertheless, some users might encounter challenges using it irrespective of the version of the tool used. Even with the exceptions, there are no formal reviews available. Still, Chadwick Center Specialists, and the treatment staff, clinicians, researchers, and doctors have commented on the instrument and manual favorably (DeFeo, 2005). Many of the staff members have expressed their liking for the scale as a measure because it can be administered easily.
Section 5: Strengths, weaknesses, and overall test evaluation
Strengths
Using BAI, patients are asked to respond to 21 items, which they rate on a scale of 0 – 3. Every item describes the subjective, panic or panic-related, somatic anxiety symptoms. It comes with steady psychometric characteristics and is sensitive to change. The BAI is comparatively short, easy to administer, and scored. The tool has also been increasingly applied in various rheumatic conditions such as arthritis and fibromyalgia.
The BAI tool is versatile and gives the users a chance to get a comprehensive measure of symptoms relating to anxiety. It also allows users to assess a wide range of emotional, cognitive, physical, and behavior related symptoms that indicate important aspects of anxiety.
BAI is reported to show clear discrimination between the anxious subjects and those who are not in diagnostic groups. The qualities are summarized as thus:
Ideal for screening anxiety
It is valid clinically valid
Can be administered easily, scored easily and interpreted just as easily
The data availed from some patients diagnosed with panic disorder with agoraphobia, panic disorder, panic disorder, minus agoraphobia, OCD, general anxiety, and social phobia.
BAI is known to be a fast screening method. It is used to diagnose anxiety. The tool can be used for self-reporting or administered orally. The list of 21 questions is precise predictors of anxiety disorder. It is, therefore, a useful diagnostic tool for clients. It can determine baselines for clients. Through the course of therapy, BAI can be applied in assessments of client symptomatology that progress. When compared to other anxiety measures, the BAI is seen to discriminate symptoms of depression better. The tool has been validated in various countries. Studies are demonstrating that the measure can be applied across a wide range of cultures. The accurate reports help the clinician and the individuals to monitor progress.
Weaknesses
The down-sides of Becks Assessment Instrument include incidences of decreased validity in certain populations, especially the older people. Just like the other tools that we have reviewed, the measure fails to detect the presence of anxiety, specifically. It only gives evidence of general anxiety signs. The self-reported questionnaires include self recalled bias risks and the fact that it cannot measure biological parameters objectively. It has also faced criticism regarding its predominant preoccupation with physical indicators of anxiety. The core weaknesses include the limited range of symptoms evaluated and the absence of studies of validation focused on rheumatologic populations (Julian, 2011).
The BAI was developed because there was a need to reduce overlap with symptoms of depression, and thus appears to target somatic signs such as dizziness and the racing of the heart. In health conditions, the symptoms have the likelihood of overlapping with some physical elements of medical complications. Therefore, there would be a need to interpret cautiously. The tool also does not assess other basic symptoms of anxiety, such as worrying and related cognitive elements of anxiety. Finally, it has been observed that the BAI fails to adequately discriminate between depression and anxiety in populations in primary care. BAI also only measures anxiety over one week.
Although a good number of items pick out the somatic anxiety symptoms, the measure does not identify other symptoms of anxiety that show in people that have been exposed to traumatic conditions. Some researchers have suggested that the BAI could be picking physiological elements of anxiety such as panic. Such elements are important in assessing PTSD. There are a high number of research studies directed at PSTD because of its high comorbidity. These studies show that many people experience panic disorders in situations of exposure to trauma and that similar symptoms seem to re-occur later (Nixon & Bryant, 2003).
BAI symptoms have been associated with health status measures (Wetherell&Gatz, 2005). This suggests that in samples that manifest health concerns such as medical trauma, a measure of anxiety that picks cognitive as opposed to somatic aspects of anxiety could be essential. Since there are studies that show that females score higher, compared to males, there is a need for separate norms based on gender. Psychometric studies of adolescents in the US have predominantly involved, largely, samples of people of the white race. There is a need to carry out more research that involves samples of people from across the cultural, racial, and ethnic spectrum.
Overall test evaluation
Given the review of the BAI above, the conclusion is that it is effective in measuring anxiety within its defined scope. However, unless it is accompanied by other tools that incorporate ruminative elements of anxiety, the BAI could render an only limited assessment of anxiety in measuring rheumatology cases.
