PMID 33195758WHAT IT FOUND
Patients with type 2 diabetes can be asked how much they want family or friends to help with diabetes care and how much help they actually receive.
The nondirective support part was dependable, but the directive support part was not.
Key findings
01The original 11-item questionnaire was reduced to a 7-item version after factor analysis.
02The nondirective support subscale had internal consistency of 0.76 for preference and 0.75 for reality, while the directive support subscale had 0.51 and 0.48.
03The scale asks both how much support patients want and how much support they actually receive.

What it does not show
The scale was tested for the first time, and the authors say more studies are needed to confirm its validity. The authors did not test whether the same person would give similar answers over time. Content validity was checked by experts without scoring each item quantitatively. The directive support subscale had poor internal consistency, so its score should not be treated as reliable. The items were based on categories from studies in an American population and tested in a Chinese community sample, so wording may not carry the same meaning in other groups. The study did not test whether using the scale changes care, behavior, or diabetes outcomes.
Declared interests
The study was supported by the National Natural Science Foundation of China, grant 71673009, and the authors declared no competing financial interests or personal relationships.
The easy way to misread this
Do not assume the directive support score is dependable. Its internal consistency was 0.51 for preference and 0.48 for reality, and the paper did not test whether using the scale improves diabetes care.
