School Nurse Confidence with Diabetes Devices in Relation to Diabetes Knowledge and Prior Training: A Study of Convergent Validity
Authors' conclusion
DDCS score is related to prior training and experience, providing evidence for the scale's convergent validity. The DDCS may be a useful tool for assessing school nurse readiness to use devices and identify areas to enhance knowledge and practical skills.
Study context
- Population
- School nurses in Pennsylvania271 completed surveys
- Outcome
- Association of DDCS score with school nurse diabetes knowledge (DKT2), experience and training
Methodological detailsconvergent validity study
- Convergent validity study
Main finding
As reported in the abstract
- Mean Diabetes Device Confidence Scale (DDCS) score (range 1-5), moderate confidence with devices overall
- 3.16±0.94
- Mean DKT2 score
- 89.5±0.1%
- Correlation of DKT2 score with DDCS score, weak and not significant (Spearman)
- r=0.12, p=0.06
- Formal device training associated with higher mean DDCS score
- p<0.001
- Assisting ≥5 students with diabetes devices in past 5 years associated with higher mean DDCS score
- p<0.01
- Student caseload 1000-1500 associated with higher mean DDCS score
- p<0.001
Observational data: associations, not effects.
