Objective:
To perform the cultural adaptation of the Health Literacy in Dentistry Scale-29 (HeLD-29) for Turkish adults and to evaluate its validity and reliability.
Design:
The Turkish version of the HeLD-29 was adapted through a forward–backward translation procedure consistent with the original 29-item, seven-subscale structure. The scale was first translated into Turkish by two independent translators and then back-translated into English by two different translators. The final analytical sample included 298 adults aged 19–70 years (117 females, 181 males). To assess temporal stability, 60 randomly selected participants completed the scale again after 7–10 days.
Results:
Test–retest reliability demonstrated excellent agreement using the Intraclass Correlation Coefficient (ICC = 0.912;
