Psychological inflexibility moderates the relationship between thin-ideal internalization and disordered eating

Area of Science:

• Psychology
• Clinical Psychology
• Eating Disorder Research

Background:

• Internalizing thinness ideals is linked to disordered eating.
• Protective factors against disordered eating are crucial for individuals internalizing thinness ideals.
• Psychological flexibility and inflexibility are explored as potential moderators.

Purpose of the Study:

• To investigate psychological flexibility and inflexibility as moderators in the relationship between thin-ideal internalization and disordered eating.
• To identify specific components of psychological inflexibility that influence disordered eating.
• To examine the role of acceptance in this context.

Main Methods:

• College women (N=201) completed measures of psychological flexibility/inflexibility, thin-ideal internalization, and disordered eating.
• Statistical analyses were used to examine moderation effects.

Main Results:

• Psychological inflexibility significantly moderated the link between thin-ideal internalization and disordered eating.
• Specific inflexibility components (Fusion, Lack of Present Moment Awareness, Lack of Values, Inaction) were significant moderators.
• Contrary to hypotheses, acceptance was positively related to disordered eating.

Conclusions:

• Psychological inflexibility exacerbates disordered eating risks associated with thin-ideal internalization.
• Interventions may need to address specific inflexible processes rather than solely promoting acceptance.
• Acceptance of thinness-related thoughts may be detrimental, highlighting the need for value-guided action.
