Evaluation of a DVD for women with diabetes: impact on knowledge and attitudes to preconception care
Diabetic Medicine, 07/11/2012
Holmes VA et al. – This study demonstrates the effectiveness of a DVD in increasing knowledge and enhancing attitudes of women with diabetes to preconception care. This DVD could be used as a prepregnancy counselling resource to prepare women with diabetes for pregnancy.Methods
- Ninety-seven women with diabetes (Type 1, n = 89; Type 2, n = 8), aged 18-40 years, completed a pre-DVD and post-DVD intervention study by postal questionnaire.
- Beliefs and attitudes associated with preventing an unplanned pregnancy and seeking preconception care were assessed using a validated questionnaire; scales included benefits, barriers, personal attitudes and self-efficacy.
- Knowledge of pregnancy planning and pregnancy-related risks were assessed by a 22-item questionnaire.
- After viewing the DVD there was significant positive change in women's perceived benefits of, and their personal attitudes to, receiving preconception care and using contraception: change in score post-DVD viewing 0.7 (95% confidence interval 0.3, 1.2), P = 0.003, and 0.8 (0.3, 1.2), P = 0.001, respectively.
- The DVD significantly improved self-efficacy, that is, self-confidence to use contraception for prevention of an unplanned pregnancy and to access preconception care [3.3 (1.9, 4.7), P < 0.001], and significantly reduced perceived barriers to preconception care [-0.7 (-1.2, -0.2), P = 0.01].
- Knowledge of pregnancy planning and pregnancy-related risks increased significantly after viewing the DVD: mean increase was 37.6 ± 20.0%, P < 0.001, and 16.9 ± 21.2%, P < 0.001, respectively.
