Psychological inflexibility is a rigid behavioral pattern that interferes with engagement in personally meaningful activities; it is the hypothesized root of suffering in acceptance and commitment therapy (ACT). Thus, the quality of its measurement affects the research, theory, and practice of ACT. The current study aimed to evaluate the discriminant validity and item performance of four measures of psychological inflexibility: the Acceptance and Action Questionnaire—II (AAQ-II), a revised version of the AAC-II (AAQ-3), the Brief Experiential Avoidance Questionnaire (BEAQ), and the Comprehensive assessment of Acceptance and Commitment Therapy processes (CompACT). We analyzed data from community (n = 253), student …

Objective: Hearing loss is a chronic condition that impacts functioning among individuals with hearing loss and caregivers of children with hearing loss. Even though treatments for hearing loss can alleviate functional impairment, psychological factors like psychological inflexibility may interfere with treatment engagement and adherence, undermining the benefits of treatment. Measuring psychological inflexibility may inform care providers’ case conceptualization, improving the quality and precision of audiological interventions. Thus, the current study aimed to develop and validate measures of psychological inflexibility in hearing loss for adults and caregivers of children with hearing loss.

Design: Participants were invited to complete an online survey. …

A Review Of Aaq Variants And Other Context-Specific Measures Of Psychological Flexibility, Clarissa W. Ong, Eric B. Lee, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Psychological flexibility refers to a way of interacting with internal experiences and the external environment that advances one toward chosen values whereas psychological inflexibility reflects rigid adherence to ineffective responses such that valued living is compromised. Psychological flexibility is a critical variable of interest in acceptance and commitment therapy, thus, accurate assessment of this construct is pertinent to professionals in the field. Numerous measures of psychological flexibility for specific conditions exist and the psychometric validation of each of these measures varies in breadth and depth. To orient professionals to the scope of available measures as well as their psychometric properties, …

Assessing Psychological Inflexibility In Hoarding: The Acceptance And Action Questionnaire For Hoarding (Aaqh), Jennifer Krafft, Clarissa W. Ong, Michael P. Twohig, Michael E. Levin

Psychology Faculty Publications

Psychological inflexibility is a psychopathological process referring to the tendency for behavior to be overly controlled by internal experiences to an extent that interferes with quality of life. Some studies indicate that psychological inflexibility is linked to hoarding, but findings have been mixed. This inconsistency may be due to reliance on general measures of psychological inflexibility in prior research as there was previously no validated measure to assess psychological inflexibility as it relates to hoarding. The present study developed and validated a measure of hoarding-related psychological inflexibility, the Acceptance and Action Questionnaire for Hoarding (AAQH) in a college student sample …

The Acceptance And Action Questionnaire – Ii: An Item Response Theory Analysis, Clarissa W. Ong, Benjamin G. Pierce, Douglas W. Woods, Michael P. Twohig, Michael E. Levin

Psychology Faculty Publications

Psychological flexibility is the act of being open to internal experiences while pursuing valued life directions and has been implicated in positive mental health. A lack of psychological flexibility has been implicated in a wide range of mental health problems. In most research, assessment of psychological (in)flexibility has been done with the Acceptance and Action Questionnaire – II (AAQ-II), yet researchers have noted that items on the AAQ-II may not adequately discriminate between responses to experiences and the experiences themselves. Furthermore, little research has examined whether items on the AAQ-II function as intended in terms of assessing psychological (in)flexibility, and …
