The items’ content are related to the core problem processes derived from an ACT/RFT perspective and specifically linked to the experience of infertility: a) Cognitive fusion (e.g., When I start thinking about my infertility it is difficult to do anything else); b) Experiential avoidance (e.g., I need to control my negative thoughts and feelings about infertility); c) Conceptualized self (e.g., Not being able to have children defines me as a person); d) Conceptualized past and future [e.g., I am invaded by thoughts and fantasies about the future (e.g., results of medical tests and treatments, whether or not I will be able to become a parent)]; e) Lack of values, confusion of goals with values (e.g., The infertility experience prevents me from getting involved with other important things in my life); f) Inability to commit with values driven actions [e.g., I often do not persist in doing things that could be important (e.g., being with friends, invest in the relationship with my partner)]. Respondents are asked to rate each item using a 1 “Never true” to 7 “Always true” scale.
