Purpose: The objective of the present study was to investigate the prevalence of the type-D personality
and identify the relationship between type-D personality, fatigue, and quality of life (QoL) in infertile
women.
Methods: A total of 149 infertile women were recruited between October 2020 and January 2021. The
participants were assessed through self-administered questionnaires using the type- D personality scale-
14, fatigue severity scale, and fertility QoL instrumental questionnaire. Data were analyzed using the
independent t-test, chi-square test, Pearson's correlation coefficients, and multiple regression analysis
using the SPSS/WIN 25.0 program for Windows.
Results: Approximately 40.9% of infertile women were classified into the type-D personality group,
which showed significantly higher fatigue and lower QoL than the non-type-D personality group. Fatigue
was the most influential factor on the QoL of infertile women (b ¼ .23, p ¼ .003), followed by the
duration of infertility treatment (b ¼ .22, p ¼ .003), type-D personality (b ¼ .18, p ¼ .025), and
relationship with spouse (b ¼ .17, p ¼ .024). These variables account for approximately 22% of the
variance.
Conclusions: Intervention programs that consider fatigue, type-D personality, relationship with spouses,
and treatment duration may be useful for improving QoL in infertile women.
