Time frame: After enrollment (before intervention) and 10 weeks later (after intervention)
The short version is a 9 item questionnaire that assesses metamemory. It consists of three scales measuring satisfaction with one's memory (MMQ Satisfaction), self-perception of one's everyday memory abilities (MMQ-Ability), and use of practical memory strategies in day-to-day life (MMQ Strategy). Items are rated on a 5-point Likert scale. The MMQ-9 demonstrates strong psychometric properties, with Cronbach's alpha scores of 0.92 for Satisfaction, 0.86 for Ability, and 0.79 for Strategy, indicating high internal consistency, and intraclass correlation coefficients of 0.89, 0.84, and 0.78, respectively, showing good test-retest reliability. Convergent validity is supported by correlations with related measures (e.g., 0.74 for Satisfaction and 0.70 for Strategy), while discriminant validity is confirmed by negligible correlations with unrelated constructs (e.g., 0.08 for Satisfaction).
