Background/Description
The Overall Anxiety Severity and Impairment Scale (OASIS) is a self-report measure of anxiety that assesses the severity and impairment caused by anxiety symptoms. It is intended to be used in a variety of clinical and research settings, and can be administered in a group or individual setting. The OASIS consists of 16 items that measure the severity and impact of anxiety symptoms on daily functioning, such as difficulty concentrating, avoidance of social situations, and physical symptoms of anxiety. The items are rated on a 5-point scale, with higher scores indicating greater severity and impairment. The OASIS has been found to be a reliable and valid tool for assessing anxiety in clinical populations, and is often used in conjunction with other measures of anxiety to assess the effectiveness of treatment for anxiety disorders.
Scoring
To score the Overall Anxiety Severity and Impairment Scale (OASIS), the responses to each of the 16 items are totaled to produce a total score. The total score can range from 16 to 80, with higher scores indicating greater severity and impairment. It is important to note that the OASIS is a continuous measure, meaning that any score within the range of 16 to 80 is possible. There is no predetermined “cutoff” score that indicates the presence or absence of anxiety. Instead, the score on the OASIS is used to assess the severity and impairment caused by anxiety symptoms in an individual, and to monitor changes in severity and impairment over time. It is typically used in conjunction with other measures of anxiety to assess the effectiveness of treatment for anxiety disorders.
Reliability and Validity
The Overall Anxiety Severity and Impairment Scale (OASIS) has been found to have good reliability and validity. Reliability refers to the consistency of a measure, or the extent to which it produces the same results over time or across different administrations. Validity refers to the extent to which a measure accurately reflects what it is intended to measure.
In the study “Development and Validation of an Overall Anxiety Severity and Impairment Scale (OASIS)” by Norman SB, Hami-Cissell S, Means-Christensen AJ, and Stein MB, the OASIS was found to have good internal consistency, with a Cronbach’s alpha coefficient of .88. This indicates that the items on the scale are highly correlated with one another and measure a single underlying construct. The OASIS was also found to have good test-retest reliability, with a Pearson’s correlation coefficient of .80. This indicates that the scale produces consistent results over time.
In terms of validity, the OASIS was found to be significantly correlated with other measures of anxiety, including the Beck Anxiety Inventory and the State-Trait Anxiety Inventory. This suggests that the OASIS is measuring anxiety and is not simply a general measure of distress. Additionally, the OASIS was found to be sensitive to changes in anxiety symptoms over time, with scores on the scale decreasing significantly following treatment for anxiety disorders. This indicates that the OASIS is able to accurately reflect changes in anxiety severity and impairment. Overall, the results of the study suggest that the OASIS is a reliable and valid tool for assessing anxiety in clinical populations.
Available Versions
There is only one version of the Overall Anxiety Severity and Impairment Scale (OASIS) that I am aware of. The OASIS is a 16-item self-report measure of anxiety that assesses the severity and impairment caused by anxiety symptoms. The items on the OASIS are rated on a 5-point scale, with higher scores indicating greater severity and impairment. The OASIS is typically administered in a group or individual setting and can be completed in 5 to 10 minutes. It is often used in conjunction with other measures of anxiety to assess the effectiveness of treatment for anxiety disorders.
