Purpose:
To translate, adapt, and assess the psychometric properties of the Sex After MI Knowledge Test in Iranian context (where MI is myocardial infarction).
Design And Methods:
A cross-sectional descriptive survey was performed. The sample comprised 250 patients with MI. Confirmatory factor analysis was applied to extract three indicators.
Findings:
The Sex After MI Knowledge Test indicated good reproducibility (Cronbach's α = .76, Intraclass correlation (ICC) = 0.729, CI = 0.7280-0.781, p < .001 ICC: Intraclass correlation). Nonnormed and normed fit indices (FI) were 0.89, and incremental and comparative FIs were 0.90. Goodness-of-fit index (GFI) and adjusted GFI were below the criteria. After a varimax rotation, the first six items of the instrument explained 58.71% of total variance.
Practice Implications:
The instrument showed acceptable psychometric properties in terms of construct validity and internal consistency. The instrument might be used to stimulate conversations patients with MI regarding sexual knowledge and concerns.
