Diabetes Attitude Scale: Validation in Type-2 Diabetes Patients in Multiple Centers in China

Abstract

ObjectiveThe aim of the paper is to report the development and psychometric testing of Diabetes Attitude Scale.MethodA prospective study was performed. The cultural equivalency and content validity of the Diabetes Attitude Scale were determined by panels of endocrinologists, physiologists, nurses and dieticians. An accurate and usable translation was obtained for each of five subscales examining attitudes on need for special training, the seriousness of type-2 diabetes, the need for controlling the condition, its psychosocial impact and the degree of autonomy given to patients in decision making. The validation was derived from 5961 patients with type-2 diabetes, recruited from 50 centers in 29 provinces throughout China between March 1st and September 30th, 2010.ResultsThe modified Diabetes Attitude Scale showed an acceptable level of internal consistency. The strength of the inter-correlations among the domains of five subscales suggests that the instrument measures related but separate domains of patients' attitudes toward diabetes. Moreover, the test-retest intraclass correlation coefficients were high enough to support the stability of the Chinese version of the third version of the scale.ConclusionsThe psychometric properties of the Chinese version of Diabetes Attitude Scale demonstrated satisfactory validity and reliability and appeared to effectively evaluate attitudes toward diabetes in patients with type-2 diabetes.

Changes in attitudes toward diabetes in nursing students at diabetes camp

“…Content validity of the DAS3 was assured by having new items generated by a panel of 22 diabetes experts. The tool has been validated with patients in Venezuela with a Cronbach's alpha of 0.628, (Marcano & Velasquez, 2019), in China with 0.813 (Lou et al., 2014) and Iran with 0.68 (Mahjouri et al., 2011). Recently, the DAS3 was validated for use by 120 Brazilian health professions, demonstrating a Cronbach's alpha of 0.60 and intraclass correlation coefficient of 0.65 (Chaves Vieira et al., 2017).…”

Evaluation of eating disorders, kinesophobia and disfunctional attitudes in patients with type 2 diabetes mellitus

“…The items are answered with a sevenpoint Likert type rating, and the responses are scored as follows: 1: strongly agree, 2: agree, 3: somewhat agree, 4: neutral, 5: somewhat disagree, 6: disagree, and 7: strongly disagree. Items 2,6,12,17,24,29,30,35,37, and 40 are scored inversely. While the lowest score that can be obtained from the scale is 40, the highest score is 280 points.…”
