# 3.6.12.280 DCLAD (Child) professional questionnaire scoring step 6 - interim THP score

## Summary

Step 6 of the professional questionnaire scoring regime gives a weighting to the scores already obtained. This adjusted THP questionnaire score becomes the interim THP questionnaire score.

Explanation: Adjustments are made in recognition of the greater impact of certain functional domains (1.1.F.280), and to ensure the assessment remains consistent throughout.

## Adjusting the raw scores (1.1.R.10)

The following table explains the steps in the adjustment of the raw scores.

Note: References to question numbers are from the Disability Care Load Assessment (Child) Determination 2010, not the claim form.

Step Description
1

Questionnaire weighting

Each of the 10 domain scores are divided by 2.
2

Milestone weighting (1.1.W.20)

For domains 1, 2, 3 and 5, 6, 7 the weighted scores are calculated by multiplying the score for each domain by 10/10.
3

Milestone weighting

For domains 4 (hygiene) and 8 (grooming), the weighted scores are calculated by multiplying the score for each domain by 10/9. This results in a higher score.

Example: A weighting of 10/9 applied to a score of 2 will provide a new result of 2.22.

Explanation: These 2 domains each have 9 milestones, compared with 10 for the other domains. An adjustment is necessary to ensure these scores have the same weight as those from other domains.

Note: For domains 9 and 10 the weighted scores are not adjusted in this step.

4

Self-care skill score

To calculate the self-care skill score the weighted scores from the 3 self-care skills domains (3, 4 and 5) are averaged by adding them together and dividing the result by 3.

Explanation: Feeding and mealtime skills, hygiene and grooming skills, and dressing skills are really 3 elements of the same functional domain of self-care skills.

5

Raw score

The raw scores are the:
• questionnaire weighted scores (step 1) for domains 9 and 10,
• milestone weighted scores (step 2 or 3) for functional domains 1, 2, 6, 7 and 8,
• average self-care skills score (step 4) divided by 3 for domains 3, 4 and 5.
6

Functional weighting for domain 1 (1.1.W.30)

The raw score for domain 1, on receptive language skills, is multiplied by 1.2.

Explanation: A weighting is applied to this domain to reflect that a disability in this area has a greater impact on the child and family.

7

Functional weighting for domain 10

The raw score for domain 10, on special care needs, is multiplied by 2.

Explanation: A weighting is applied to this domain to reflect that a disability in this area has a greater impact on the child and family.

8

Interim THP questionnaire score

The total weighted scores for each domain are calculated by adding the functional weighting scores for functional domains 1 and 10, and the raw scores for domains 2 - 9. These scores are added together to calculate an interim THP questionnaire score.
