Objective: The aim of this study was to translate the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) into Turkish, validate the questionnaire, and provide a cross-cultural adaptation. Methods: The translation process included the following steps, which were performed by a translation committee: (1) translation into Turkish, (2) back translation into English, (3) pretesting, and (4) cross-cultural adaptation. The Turkish version of the PIDAQ was produced subsequent to the translation process. Validity and reliability were measured using the Perception of Occlusion Scale and the aesthetic component of the Index of Orthodontic Treatment Need. The questionnaire was administered to 260 individuals (age range, 18-30 years; mean age, $20.50{\pm}1.9$ years). Structural validity was assessed via factor analysis, and internal consistency was measured using Cronbach's alpha coefficient. Results: Factor analysis revealed a four-factor structure, with factor loadings for included items ranging from 0.380 to 0.868. Few questions were shuffled among domains various factor loadings. Cronbach's alphas for the Turkish version of the PIDAQ ranged from 0.534 to 0.904. Mean scores for the PIDAQ subscale and total scores differed significantly according to Index of Orthodontic Treatment Need and Perception of Occlusion Scale scores. Conclusions: This study provided a Turkish version of the PIDAQ, which could be a useful tool in the evaluation of the psychosocial impact of malocclusion in young Turkish adults.

Evaluation of nutritional status of the elderly imposes different problem from the other age groups. It is essential to use right instrument to assess food consumption. In Korea, the food frequency questionnaire has not been applied widely to elderly people. The purpose of this study is to assess the possibility of employing a semi-quantitative food frequency questionnaire(FFQ) for the Korean elderly to estimate nutrient and/or food intakes. In this study the FFQ for the elderly was developed and validated. The subjects were 144 free-living old women aged from 65 to 90. The FFQ was designed with 4 items for cereals and 86 items for other foods and with frequency of 12 intervals. Three portion sizes were given to select : 1/2 of standard amount, standard amount, and 11/2 of standard amount. ach subject was interviewed with newly developed FFQ form and same subjects were also involved to complete 3-day diet record. Nutrient intake was calculated using software program developed by our group. The nutrient intakes by the FFQ was validated by comparing the results with 3-day diet record. The FFQ estimated significantly higher mean intakes of energy, carbohydrate, protein, fats and vitamin C than did the diet reconrds(p<0.05). Pearson's correlation coefficients between two methods ranged from 0.21 for vitamin Q to 0.69 for alcohol(mean r=0.53). From 32% to 42% of the subjects were classified in the same quintile of nutrient intake by two methods, and 63% to 84% were classified in the same or adjacent quintile. On average, only 4% of the subjects were misclassified into extreme quitiles. The results indicate that the FFQ developed for the elderly in this study is useful for classifying individuals by rank and identifying groups at extremes of nutrient intakes.

Background: The amount of smoking in adolescence increases with a younger age of smoking initiation and affects physical health. To establish and evaluate smoking-related policies, it is important to determine actual smoking status. Validation of self-reported questionnaires can identify the accuracy of the questionnaire data reflecting smoking status. Objectives: The purpose of this study was to evaluate the validity of self-reported smoking status and identify factors affecting the accuracy of self-reported smoking in South Korean adolescents. Methods: This study investigated the consistency between cotinine concentrations and self-reported questionnaire data through the analysis of urine samples collected from 922 adolescents aged 13~18 among the participants of Cycle 3 of the Korean National Environmental Health Survey. Smoking status was classified using the cotinine cut-off point of 39.85 ㎍/L in adolescents, and factors affecting the accuracy were analyzed through multiple logistic regression analysis. Results: The smoking rates according to the self-reported questionnaire and cut-off point-based cotinine concentrations among adolescents were 3.1% and 5.1%, respectively. The results found 97.1% consistency between self-reported smokers and smokers according to cotinine concentration. Factors affecting the discrepancy showed a significant relationship, including gender, secondhand smoke, and use of e-cigarettes. Conclusions: The results can be used as basic data to establish a smoking policy for adolescents through continuous monitoring and improvement of questionnaire items of factors affecting the discrepancy.

This study was conducted to develop a simple flood frequency questionnaire (FFQ) based on the results of contributions of specific floods to absolute intake and between-person variance in nutrients using semi-quantitative FFQ with 93 flood items. The subjects were 554 healthy adults for development of a simple FFQ, and 37 students for a validation test of a developed simple FFQ. The contribution of specific floods to 80% absolute nutrient intake was measured by assessing their percentage in total consumption of a nutrient. To assess the contributions of floods to the between-person variance in the intake of each specific nutrient, stepwise multiple regressions were performed. The number of floods necessary to account for the respective 80% of absolute intake was 11-36, depending on the nutrient, while flower floods (5-16 floods) were required for the corresponding percentage of between-person variation for all nutrients. Important floods for between-person variance include Tangsuyuk (pork) and snacks for energy and fat, fish for protein and polyunsaturated fatty acids (PUFA) and snacks for carbohydrates. Spearman correlation coefficients between 93-itemed FFQ and 63-itemed FFQ ranged from 0.91 for vitamin A to 0.99 for fat in the population data used in developing a simple FFQ. Also, the correlation coefficients between the two FFQs were 0.82-7.92 in the population for the validation test. This study suggests that useful information on dietary intake could be obtained using a simple semi-quantitative FFQ in a large-scale dietary survey in Korea.

Background: The object of this study was to assess the validity and reliability of the Korean versions of chronic obstructive pulmonary disease assessment test (CAT) and Dyspnea-12 Questionnaire for patients with chronic pulmonary obstructive disease (COPD). Methods: For the 127 COPD patients, we obtained the Korean versions of the 3 questionnaires being tested: St George's Respiratory Questionnaire (SGRQ), CAT, and Dyspnea-12 with spirometric measurements. To assess the validity of CAT and Dyspnea-12, their correlation with SGRQ was evaluated. To assess the reliability of CAT and Dyspnea-12, Cronbach's alpha coefficient was evaluated. Results: The mean age of patient participants was $68.6{\pm}7.5$ years; 97.6% were male. The SGRQ score was correlated with the scores of the Korean version of CAT (r=0.71, p<0.0001) and Dyspnea-12 (r=0.73, p<0.0001). The Cronbach's alpha coefficient for the CAT and Dyspnea-12 were 0.77 and 0.78, respectively. Conclusion: The Korean versions of CAT and Dyspnea-12 were shown to be valid and reliable for the Korean COPD patients.

Despite the recent sharp growth in the baby product market, previous studies on preschooler clothing have centered primarily on surveys regarding body size and consumer buying behavior, with little emphasis given to consumption value in preschooler clothing. This study aimed to assess the feasibility of using standards of consumption value to examine the behavior of those who buy preschooler clothing. The research subjects were mothers of preschoolers aged 1 to 6 years. They were asked to complete a questionnaire online at major parenting blogs found on portal sites (n=346). The questionnaire contained 41 questions based on a literature review, and 25 questions having convergent and discriminant validity were analyzed. By conducting a regression analysis of standards of consumption value in preschooler clothing and their perceived value, the feasibility of the standards was assessed. The results showed that consumption value in preschooler clothing was associated with 21 questions and 8 factors. The factors measuring consumption value included vicarious satisfaction, social value, functional value, convenience, financial value, aesthetic value, uniqueness, and circumstantial value. This study is significant in that it expands the scope of research on preschooler clothing, lays the groundwork for measuring consumption value in preschooler clothing, and predicts consumer behaviors by identifying the consumption value among mothers of preschoolers.
