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

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, <italic>p</italic> < .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. [ABSTRACT FROM AUTHOR]
