The aim in this study is to determine the Turkish version validity and reliability of the Fonseca Anamnestic Index.

Approximately 60% of individuals with temporomandibular disorders (TMD) reported increased pain intensity from midlevel to severe. This was seen at the end of the intervention or work related activities in the quarter of individuals. Therefore, the correct diagnosis of TMD is very important to reduce the economic cost. Fonseca Anamnestic Index (FAI) is an easy and understandable questionnaire. This questionnaire consists of 10 questions that provide a versatile evaluation of the temporomandibular joint (TMJ) in the head and neck, whether there is pain during chewing, the presence of parafunctional habits, range of motion, joint sounds, malocclusion, and emotional stresses. The participants give one of the answers to the questions "Yes = 10 points, Sometimes = 5 points, No = 0 points". As a result of the total of the points, the participants are evaluated as "TMD-None = 0-15 points, Mild-TMD = 20-40 points, Moderate TMD = 45-60 points, Severe-TMD = 100 points". The aim of this study was to evaluate the validity and reliability of the Turkish version of FAI. The study of validity and reliability is planned with 50 individuals with TMD. The sociodemographic characteristics of the individuals will be questioned by the investigators and then the patients will be evaluated with FAI, Craniofacial Pain and Disability Inventory (CF-PDI), Neck Disability Index (NDI), Tampa Scale for Kinesiophobia (TSK), Pain Catastrophizing Scale (PCS), Headache Impact Test-6 (HIT-6), Jaw Functional Limitation Scale (JFLS) (Turkish version) and Visual Analogue Scale (VAS). The test-retest will be re-administered by face-to-face interview technique after 1 week. The results will be analyzed using the SPSS version 22.0 computer package program.
