PMID 31406866WHAT IT FOUND
Japanese adults with type 2 diabetes described views of connecting with others who have diabetes on a 36-item questionnaire.
It captured perceived benefits, barriers, diabetes worry, positive and negative social feelings, and self-management ability. It did not test whether peer support improves diabetes care.
Key findings
01The final scale contained 36 items grouped into six factors: perceived benefits, perceived barriers, perceived severity of diabetes, positive attitude, negative attitude, and perceived self-management ability.
02The scale was analysed in 289 patients with type 2 diabetes after excluding those with missing answers.
03The scale's items hung together consistently: the whole scale scored 0.893, and subscales scored from 0.719 to 0.911.

What it does not show
Only Japanese patients with type 2 diabetes were studied, so the scale may not work the same way in other cultures. Patients with serious complications, cognitive impairment, gestational diabetes, or communication difficulty were excluded, so it says nothing about those groups. The study tested measurement properties only; it did not test whether peer relationships, nurse advice, or use of the scale improves diabetes self-management or health outcomes. The factor structure found six factors instead of the expected four, so the original concept map did not fit perfectly. Of 378 questionnaires distributed, 289 were analysed after missing answers were excluded. Concurrent validity was partial: the total score and three subscales correlated with a reciprocity scale, while three subscales did not.
Declared interests
The study did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
The easy way to misread this
Do not conclude that peer support improves diabetes outcomes or that this scale has been shown to change nurse care. It measured patients' views in one Japanese sample and did not test whether using it helps self-management or blood glucose control.
