Psychometric Evaluation of the Sex After Myocardial Infarction Knowledge Test in Iranian Context

To translate, adapt, and assess the psychometric properties of the Sex After MI Knowledge Test in Iranian context (where MI is myocardial infarction).A cross-sectional descriptive survey was performed. The sample comprised 250 patients with MI. Confirmatory factor analysis was applied to extract three indicators.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.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.
