Received 15 February 2008; received in revised form 18 March 2008; accepted 18 March 2008. published online 13 June 2008.
Objective
To develop the Cognitive Appraisal Scale for Infertility (CASI) and assess it for reliability and validity.
Design
Cross-sectional and longitudinal study.
Setting
A private fertility institute in Japan.
Patient(s)
223 infertile women being treated at the institute.
Intervention(s)
Administration of questionnaire at initial consultation and 6 months later.
Main Outcome Measure(s)
A self-rating questionnaire of perceptions and feelings about infertility on a four-point Likert scale, the State-Trait Anxiety Inventory (STAI), and the Self-rating Depression Scale (SDS). Internal consistency (Cronbach's α), test–retest reliability coefficients, and concurrent validity correlations.
Result(s)
Factor analysis identified eight factors with 35 items: difficulty accepting infertility, decrease in self-esteem, acceptance/coming to terms with new self-identity, despair, loss of libido and erosion of marital relationship, guilt, denial, and self-imposed isolation. Internal consistency for factors 1 and 2 was 0.88 and 0.82, for factors 3 to 8 was from 0.68 to 0.58. Test–retest reliability coefficients were 0.90 to 0.72. Concurrent validity correlations between CASI and STAI, and SDS ranged from 0.54 to 0.29.
Conclusion(s)
The CASI, a new and potentially useful scale to assess emotional responses to infertility, is still in development. Further refined CASI and standardized scores of each subscale could be efficient for clinical practice.
