Abstract

Purpose

The patient-reported outcome becomes important to evaluate the situation perceived by the patients and to develop new strategies. This study aims to adapt the Acromegaly Treatment Satisfaction Questionnaire (Acro-TSQ), which was specially developed for patients with acromegaly, into Turkish by conducting a validity and reliability study.

Methods

After the translation and back-translation process, Acro-TSQ was filled in by face-to-face interviews with 136 patients diagnosed with acromegaly and currently receiving somatostatin analogue injection therapy. Internal consistency, content validity, construct validity, and reliability of the scale were determined.

Results

Acro-TSQ had a six-factor structure and explained 77.2% of the total variance in the variable. The Cronbach alpha value calculated for internal reliability showed high internal consistency (Cronbach’s alpha = 0.870). Factor loads of all items were found to be between 0.567 and 0.958. As a result of EFA analysis, one item fell into a different factor in the Turkish version of the Acro-TSQ, different from its original form. CFA analysis shows that acceptable fit values are obtained for fit indices.

Conclusion

The Acro-TSQ, a patient-reported outcome tool, shows good internal consistency, and good reliability, suggesting it is an appropriate assessment tool for patients with acromegaly in the Turkish population.
