Psychological Assessment 

Psychological assessments can be an extremely useful tool to measure a range of factors and assist in understanding neuropsychological, behavioural and emotional functioning. These instruments below however are not useful in isolation and require a specific question, background data and collateral information. A Psychological assessment is the combination of clinical interviews, observations, self-reports, alternative sources of information and psychometric instruments. Below are some of the most common psychometric tools used along with a brief description.   

 

WISC-V

The Wechsler Intelligence Scale for Children (WISC-V) is designed for children aged 6-16 years old and takes approximately 50-70 minutes to complete. The WISC-V provides a general overview of a child's cognitive functioning and intelligence.

Scores derived form the WISC-V include a Full-Scale IQ, Verbal Comprehension Index, Visual Spatial Index, Fluid Reasoning Index, Working Memory Index, and Processing Speed Index. Scores indicate a child's ability against the normal population and gives insight into cognitive functioning, deficits, strengths and learning difficulties.   

The WISC-V is mainly used in a battery of tests to assess cognitive functioning, the need for educational intervention, cognitive development and to assess for learning difficulties. 


WAIS-IV

The Wechsler Adult Intelligence Scale (WAIS-IV) is designed for adults and older adolescents aged 16-90 years old and takes anywhere between 1-2 hours to complete. The WAIS-IV provides a general overview of an adults cognitive functioning and intelligence. 

The WAIS-IV provides 6 scores including the Full-Scale IQ, The General Ability Index, Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed. Scores are compared to a sample that is representative of a normal distribution in the population. 

The WAIS-IV can be used to obtain a comprehensive assessment of general cognitive functioning. When use din a battery the WAIS-IV can also assist in identifying intellectual disabilities, cognitive strengths and weaknesses. Results can guide treatment planning and occupational decisions. 


WMS-IV

The Wechsler Memory Scale (WMS-IV) is a neuropsychological assessment of memory in adolescents and adults aged 16-90 years old and takes approximately 90-120 minutes to complete. The WMS-IV measures memory functioning.   

The WMS provides 5 scores in relation to a person's memory including Auditory Memory, Visual Memory, Visual Working Memory, Immediate Memory, and Delayed Memory.

Due to the specificity of the WMS-IV it is designed to be used within a battery of tests to provide a robust picture of memory functioning. This can be useful for neuropsychological assessments, identifying impairments or detoriation in memory and also useful for better understanding cognitive functioning. 


CMS

The Child Memory Scale (CMS) is a comprehensive learning and memory assessment designed to evaluate learning and memory functioning for ages 5 - 16. The CMS takes approximately 35-50 minutes to complete. 

The CMS assesses functioning in 3 domains including auditory/verbal learning & memory, visual/nonverbal learning & memory, and attention/concentration.   

The CMS is useful in analysing learning and memory processes along and in a battery can be used to identify disabilities such as ADHD, specific language impairment, learning disabilities and other neurological conditions. 


PAI

The Personality Assessment Inventory (PAI) is a 344-item self report  assessment that assesses personality and psychopathology. It takes approximately an hour to complete.

The PAI can be administered for a variety of reasons including information in regards to psychopathology, treatment planning, crisis intervention, family separation and suitability for nominated occupational roles. 


WIAT-III

The Wechsler Individual Achievement Test (WIAT-III) is designed to measure academic achievement for individuals aged 4-50 years. The WIAT III takes approximately anywhere between 70-140 minutes to complete.

The WIAT-III assesses achievement across 4 domains including Mathematics, Oral Language, Reading and Written Expression. 

The WIAT-III  is used to identify academic strengths  weaknesses, inform decisions regrading eligibility for educational services and assist in the diagnosis of specific learning disorders.
