[Validation of the Questionnaire of Emotional Maladjustment and Adaptive Resources in Infertility (DERA)]

Validation of the Questionnaire of Emotional Maladjustment and Adaptive Resources in Infertility (DERA). Given the absence of measures to help psychologists working with infertile couples, this paper presents the process of developing a standardized measure to assess emotional maladjustment and adaptive resources in this population. A cross-sectional design was utilized to gather data from the assisted reproduction units of two public hospitals. Preliminary analyses were performed with a sample of 85 infertile patients. Psychometric properties of the measure were tested with a second sample of 490 infertile patients. Concerning reliability analyses, alpha indexes were adequate both for the measure and its factors. Concerning validity, second-order factor analysis yielded a four-factor solution that conjointly explains 56% of the total variance. Additional analyses with a third sample of 50 participants from the general population matched with a sample of 50 infertile participants were performed. In sum, this measure seems to be a useful psychological assessment tool to determine emotional adjustment, and individual, and interpersonal resources, for coping with infertility diagnosis and treatment.
