| Description | The Acquiring Motives Questionnaire (AMQ; David, Forbes, & Norberg, 2024) is designed to measure psychological motivations underlying excessive acquisition of possessions. Developed in conjunction with the Saving Motives Questionnaire (SMQ), it was constructed based on a comprehensive literature review and expert consultation. The 55-item scale was evaluated using nonclinical and clinical samples, including individuals with hoarding disorder (HD) and compulsive buying-shopping disorder (CBSD), as well as control participants. Findings from factor analysis, item response theory, reliability, and validity assessments were reported to support the scale’s development and applicability. |

| Format | Participants rate statements on a 5-point Likert scale: 0 = “never,” 1 = “rarely,” 2 = “sometimes,” 3 = “frequently,” and 4 = “very often.” Subscale scores are averaged, with higher scores indicating greater motivation. |
| Administration Method | Electronic |
| Number of Items | 55 |
| Factors and Subscales | Subscales include: Positive Social, Positive Sales, Positive Reward, Positive Use/Info, Positive Historical, Positive Helping Others, Positive Identity, Positive Collecting, Positive Beauty, Negative Social, Negative Sentimental, Negative Mistakes, Negative Coping, and Negative Collecting. |
| Reliability | Internal Consistency: Subscale reliability ranged from ω = 0.81 to 0.92. Test-Retest Reliability: Most subscales demonstrated ICCs between 0.70 and 0.88, except Positive Use/Info (ICC = 0.67) and Positive Helping Others (ICC = 0.68), which were slightly below 0.70. |
| Validity | Construct Validity: Supported by factor and item response theory analyses. Convergent and Divergent Validity: Stronger correlations were observed between similar subscales (e.g., AMQ Positive Social and SMQ Positive Social). Criterion Validity: Demonstrated through correlations with measures of hoarding and compulsive buying, as well as the ability to differentiate between controls and individuals with HD and/or CBSD. |
| Factor Analysis | Exploratory Factor Analysis: Initial analyses identified 13 factors. Confirmatory Factor Analysis: Supported a 14-factor model, which was superior to alternative models. |
