Purpose of the Questionnaire (Scale)

The TAVM-15 is primarily designed to measure short-term memory dynamics, focusing on an individual’s ability to retain and recall information over a brief period. The questionnaire is intended for use with adults and older individuals, particularly those showing signs of memory decline. It is utilized by researchers, clinical psychologists, and cognitive assessment specialists for diagnosing memory disorders and evaluating the impact of age or potential interventions on memory recall.

Questionnaire (Scale) Analysis

The TAVM-15, developed by A. Maridaki-Kassotaki in 1998, includes 15 exercises assessing the ability to retain and recall numbers, words, or visual information within a limited timeframe. The tool is structured into three subscales:
Phonological Retention (e.g., repetition of nonwords),
Visuospatial Retention (e.g., recall of visual patterns),
Sequential Recall (e.g., recall of digit sequences).

Scoring

Each correct response earns 1 point. The maximum score per subscale is 5, with a total score of 15. Higher scores indicate better short-term memory performance.

Statistical Analysis

The total score range is from 0 to 15:
Scores from 0 to 5 indicate low retention capacity,
6 to 10 reflect moderate retention,
11 to 15 denote high retention.
For the individual subscales, a score of 2 or less is considered weak, while a score of 4 or more is deemed strong.

Validity of the Questionnaire (Scale)

The TAVM-15 demonstrates high validity, supported by its correlation with established memory assessment tools such as Baddeley’s Working Memory Model, and by findings from scientific studies, including those by Gathercole et al. (1994) and Maridaki-Kassotaki (1998).

Reliability of the Questionnaire (Scale)

The test shows excellent internal consistency, with a Cronbach’s alpha of 0.89, and high test-retest reliability, with r = 0.92, indicating stability in measurement.
