SCAS Preschool Scale

SCAS Preschool Scale

A validated, parent-rated version of SCAS is appropriate for youth ages 3-6. The measure comprises six subscales. Clinicians can administer this measure in five to ten minutes. They rated each item on a 4-point Likert scale from zero (“Never”) to three (“Always”). 

The youth self-report version shows high internal consistency (α = .92-.93), adequate test-retest reliability over six months (α=.60), and high concurrent validity with the RCMAS (Reynolds & Richmond, 1978; Spence, 1998). The parent-report version correlates significantly with the youth self-report version and the DSM-IV-TR criteria of the anxiety disorders associated with the SCAS subscales. The SCAS is available in over 20 languages (e.g., Chinese, Spanish, Arabic, and Japanese).

Alcohol Use Disorders Identification Test (AUDIT): Brief Description and Interpretation

Brief Description and Interpretation of Alcohol Use Disorders Identification Test 

Alcohol Use Disorders Identification Test (AUDIT) was developed by the WHO; the total number of items is 10. The maximum score of each item is 4. The minimum is 0, so the total score is 10x4=40, and the minimum is 0. Item 0 to 8 has a scoring of 0,1,2,3,4 i.e. five anchors while item 8 and nine has 3 anchors each with scoring of 0,2,4. It is used to assess alcohol consumption, drinking behaviours, and alcohol-related problems. It is most suited for primary care physicians and shows good sensitivity and specificity. If the score is above 8.

Symptoms and Functioning Severity Scale (SFSS): A Summary Scoring and Interpretation

Symptoms and Functioning Severity Scale (SFSS)

The key measure of therapy success is the Symptoms and Functioning Severity Scale (SFSS).1 

This scale examines the intensity of general symptoms and symptoms related to children and adolescents' most prevalent mental health problems (ADHD, CD, ODD, depression, and anxiety). 
It comprises a 5-point Likert scale for each item ("never," "rarely," "occasionally," "frequently," and "very often"). A total score, an externalising score, and an internalising score are all provided by the SFSS. Youngster, caregiver, and clinician versions are available.  A 26-item version (SFSS-Full) and 2 other variations (SFSS Short Form A and Short Form B) are the different versions. Therapists apply these later 2 versions during alternate therapy sessions to assess change over a short period (i.e., weekly or biweekly sessions).

The Clock Drawing Test

 The Clock Drawing Test

The clock drawing test is one of the most popular and quickly applicable neuropsychiatric test that we use to detect dementia in patients with suggestive signs of dementia. The application of the clock drawing test utilises the following cognitive abilities of the patient:
  1. Verbal comprehension
  2. Working memory
  3. Spatially coded knowledge
  4. Constructive skills
  5. Planning, which is one of the executive function functions

The clock drawing test DOES NOT test orientation to time.

Scoring and Administration

to administer and score
