Development and validation of the Acquiring and Saving Motives Questionnaires: For use in clinical and nonclinical populations.

Our consumer-driven culture has negative impacts for individuals who are vulnerable to clinical hoarding and compulsive shopping. Because of this, there is an ever-present need to have standardized tools to assess why we acquire and save things we might not need. In this article, we present the development of the Acquiring Motives Questionnaire (AMQ) and Saving Motives Questionnaire (SMQ), which were written based on a thorough literature review and consultation with 22 experts in the field. After piloting with two large nonclinical samples, we administered the measures to another large nonclinical sample (N = 535; Mage = 24.4, 74.2% female, 54.6% White) and then a community sample of individuals with hoarding disorder and/or compulsive buying-shopping disorder and controls without any mental health diagnoses (N = 159; Mage = 42.54, 85.5% female, 59.7% White). Confirmatory factor analyses supported a 14-factor model for the AMQ and a 14-factor model for the SMQ. All subscales demonstrated good internal consistency (ω = 0.81-0.96), 2-week test-retest reliability (intraclass correlation coefficient = 0.67-0.83), and convergent, divergent, and criterion validity. The measures also distinguished between controls and individuals with hoarding and/or compulsive buying diagnoses. Findings highlight that acquiring and saving behaviors are both motivated by the pursuit of positive emotions and the avoidance of negative emotions, which is consistent with our theoretical understanding of these clinical issues. Based on our findings, we make suggestions for psychological interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
