The psychometric properties of the Diabetes Self-Efficacy Scale in Saudis with type 2 diabetes.

PMID 37319293WHAT IT FOUND
The Arabic eight-item diabetes self-efficacy scale had consistent scores and was related to self-management in 154 Saudi adults.
Nurses in Saudi primary care can use it to quickly assess confidence in diet, activity, blood sugar monitoring, and follow-up.
Key findings
01The Arabic Diabetes Self-Efficacy Scale had Cronbach's alpha 0.86, corrected item-total correlations from 0.46 to 0.70, and no item-total correlation below 0.30.
02Exploratory factor analysis found one factor, self-efficacy for diabetes self-management, with all eight items loading above 0.30 and 55.34% of variance explained, and confirmatory factor analysis fit adequately after modelling error correlations (TLI 0.97, CFI 0.98, RMSEA 0.05).
03Arabic self-efficacy scores were related to Arabic self-management scores (r = 0.40, p < 0.001).

What it does not show
Participants were a convenience sample from two primary healthcare centres in one district of Riyadh, so results may not apply to other Saudi regions or settings. Data were collected at a single point in time, and test-retest reliability was not performed. The study was done in one Arabic-speaking country, so generalisability to other Arabic-speaking populations needs testing. The original two-factor structure was not supported; exploratory factor analysis found one factor. The raw confirmatory model did not fit well and only fitted adequately after modelling error correlations. No clinical outcomes were measured, so this does not show that using the scale improves diabetes control.
Declared interests
Funding came from the Deanship of Scientific Research at King Saud University through the College of Nursing Research Center. The author declared no potential conflicts of interest.
The easy way to misread this
Do not read this as evidence that using the scale improves diabetes control. It was tested only once in 154 Saudi adults from two primary care centres, and no test-retest reliability or patient outcomes were reported.
