Abstract:
Objective:To evaluate the validity and reliability of the Problem Area in Diabetes Scale (PAID) for assessing diabetes-related distress in patients with type 2 diabetes. Methods:Totally 203 outpatients with type 2 diabetes from a tertiary hospital in Beijing were selected. They were assessed with PAID,Hamilton Depression Scale (HAMD-17),Patient Health Questionaire-9(PHQ-9),World Health Organization Five item Well-Being Index (WHO-5 ),Mini-International Neuropsychiatric Interview (MINI)and HbA1 C. Item analysis and exploratory factoranalysis were conducted to test constructive validity. Concurrent validity was evaluated by the correlation coeffi-cients with the other instruments mentioned above. Totally 3 1 subjects were retested 4 weeks later to obtain the test-retest reliability. Results:Exploratory factor analysis produced 4 factors,including emotional,therapeutic,diet and perceived society support problems specific to diabetics. The total variance contribution ratio was 64. 33%. Except i-tem 7 and 20,no item was across two factors. The correlation coefficients of each item with relevant subscale score ranged from 0. 67 to 0. 86. The PAID scores were positively correlated with the scores of HAMD-17,PHQ-9 and HbA1C (r=0. 48,0. 43,0. 21,P<0. 001 or 0. 01),and negatively correlated with WHO-5 scores (r=-0. 46,P<0. 001). The Cronbach's αcoefficients were 0. 94 for the total scale and 0. 81 -0. 88 for the 4 subscales. The test-retest reliability coefficient was 0. 65 for the total scale and 0. 53-0. 73 for the 4 subscales. Conclusion:The validi-ty and reliability of the Problem Area in Diabetes Scale are acceptable in Chinese mainland,and can be available to assess the stress related to diabetics.
