BASIS-24 Pre and Post-test Assessments With Patients

This data is best viewed on a desktop computer or tablet. If you are using a mobile device, please turn your device horizontally to view.

The psychometric properties of the BASIS-24 were determined through field testing (inpatient N= 2,623; outpatient N= 3,228). Internal Consistency coefficients (Cronbach’s alpha) were computed for each BASIS-24 subscale and for the overall score, Test-Retest Reliability coefficients analysis demonstrated excellent test-retest reliability, and Discriminant Validity indicated significant differences between subject groups.

The Behavior and Symptom Identification Scale (BASIS-24) consists of 24 items divided into 6 subscales and is a self-administered tool structured to assess co-occurring mental health and/or substance abuse treatment from the patient’s perspective. Behaviors and symptoms relating to the prior week are rated by the patients taking the survey upon admission and discharge.

The six subscales include the following:

  • Depression and level of adaptive functioning, including difficulties with concentration, coping strategies, nervousness and depressive symptoms
  • Relationships, focusing on feeling connected and compatibility with others
  • Self-Harm, such as suicidal ideation
  • Emotional Lability, emphasizing mood and dysregulation
  • Psychosis, including auditory and visual hallucinations as well as persecutory thoughts/beliefs
  • Substance Abuse, highlighting urges, cravings, and repercussions

There is also an overall score which is a composite of the means of all 24 items.

Below are the full results of the BASIS-24.

BASIS-24 Total Mean Differences

The overall findings of the Behavior and Symptom Identification Scale (BASIS-24) indicate that when patients first admitted to Evolutions Treatment Center, their perception of and emotions related to different areas of their life (including depression and level of functioning, including concentration, coping strategies, nervousness and depressive symptoms, relationships, focusing on connection and compatibility, self-harm and suicidality, emotional dysregulation and mood issues, psychotic symptoms, as well as urges, cravings, and repercussions associated with substance abuse) were more difficult or problematic at admission than upon discharge from treatment. Patients reported that they had between a little to a moderate level of difficulty (1.2263) overall in the above domains upon admission to treatment. Upon discharge, patients’ perceived level of difficulty lowered to between experiencing a little difficulty to no difficulty (.6788) in these same domains. This difference in level of perceived difficulty was statistically significant when conducting a two tailed paired samples T-Test with a 95% confidence interval.
