This study aimed to conduct the validity and reliability of the (Pictures of Facial Affect) POFA test for the Turkish population and contribute to increasing the number of tests that are still insufficient in our country.
This descriptive, randomized controlled study was conducted in two steps, namely Step 1 (Pilot Study and Validity Studies) and Step 2 (Reliability Study Step). The number of participants was planned regarding the original study by which the POFA test was developed. The EYES test was also used for comparison. In the pilot study, the most widely identified emotions from 47 of 110 photos in the POFA test were chosen as the new POFA picture set to be used in the reliability and validity study under the name "POFA Test Short Form". A total of 100 participants, including 82 healthy volunteers and 18 essential tremor (ET) patients, were enrolled in the first step of the study. Another cohort of 22 healthy volunteers was enrolled in the second step of the study for test-retest reliability analysis.
A significant positive correlation was found between the total POFA Test Short Form and EYES Test scores in the healthy volunteer group in terms of criterion-related validity (r=0.44, p<0.01). There were statistically significant differences between healthy volunteers and ET groups regarding EYES Total, POFA Total, POFA Sadness, POFA Anger, and POFA Neutral scores. It was observed that the 47-item POFA Test Short Form total score showed skewness and kurtosis, which demonstrated suitability for clinical use.
The POFA Test Short Form was found to be a valid and reliable assessment tool in the Turkish population to be used in studies on emotion recognition and was shown to be beneficial for the discrimination of healthy individuals and ET patients.
本研究旨在对土耳其人群进行面部表情图片（POFA）测试的有效性和可靠性评估，并为增加我国目前仍较为匮乏的测试数量做出贡献。
本描述性随机对照研究分两步进行，即第一步（预试验和效度研究）和第二步（信度研究阶段）。根据最初开发POFA测试的研究来规划参与者数量。还使用EYES测试进行比较。在预试验中，从POFA测试的110张照片中的47张里最常识别出的情绪被选为新的POFA图片集，用于信度和效度研究，命名为“POFA测试简表”。研究的第一步共招募了100名参与者，包括82名健康志愿者和18名特发性震颤（ET）患者。研究的第二步又招募了22名健康志愿者进行重测信度分析。
在健康志愿者组中，就效标关联效度而言，POFA测试简表总分与EYES测试得分之间存在显著正相关（r = 0.44，p < 0.01）。在EYES总分、POFA总分、POFA悲伤、POFA愤怒和POFA中性得分方面，健康志愿者和ET组之间存在统计学显著差异。观察到47项POFA测试简表总分显示出偏态和峰态，表明适合临床使用。
发现POFA测试简表是土耳其人群中用于情绪识别研究的有效且可靠的评估工具，并且显示出对区分健康个体和ET患者有益。
