Number of items7 (one per transformational behavior)
Response format5-point frequency scale (1 = Rarely or never to 5 = Very frequently, if not always)

Dimensions & subscales

Unidimensional by design — seven single items (vision, staff development, supportive leadership, empowerment, innovative thinking, leading by example, charisma) that form one global transformational-leadership score.

Reliability (commonly reported)

Alphas are commonly reported around .90–.93.

Validity evidence

Validated against the MLQ and the Leadership Practices Inventory with strong convergent correlations; the single-factor structure is consistently supported. Its brevity trades away subdimension diagnostics, which the authors acknowledge.

Populations & contexts

Originally Australian bank employees rating branch managers; since used across sectors and countries wherever a brief transformational measure is needed.

Origin, translations & adaptations

Australia. Translated into several languages; often chosen in multi-construct surveys for its low respondent burden and free availability.
