BACKGROUND/OBJECTIVES:
The illustrated Healthy Eating Practice Questionnaire (HEPQ) was previously developed to assess food preferences, eating behaviors, hand/oral hygiene practices, and nutrition knowledge among Korean preschool children. Nevertheless, the lack of an integrated scoring system has limited its interpretability. This study developed a scoring system and a web-based platform with tailored feedback using a child-parent dyad approach.
SUBJECTS/METHODS:
The development process consisted of 5 phases: 1) questionnaire preparation for online use, 2) formulation of the scoring system, 3) determination of the cut-off values for three levels of healthy eating practices based on a child-parent survey, 4) technical development of the online platform, and 5) usability evaluation. A scoring system was established by standardizing the domain scores to a 100-point scale. One hundred child– parent pairs participated in the survey to calculate the Healthy Eating Practice Score (HEPS) and determine cut-off values for the HEPS levels. The validity of the cut-off values was examined by a comparison with the Nutrition Quotient for Preschoolers (NQ-P). A web-based platform was developed, and 47 child–parent pairs were used to assess its usability.
RESULTS:
Significant positive correlations were observed between child and parent HEPS across all domains. The HEPS-based classification showed good discriminative ability because higher HEPS levels were consistently associated with higher NQ-P scores in children and parents. The web-based HEPQ was easy to use and understand, and almost all participants (97.9% of children and 93.6% of parents) reported no difficulties using the platform.
CONCLUSION
The web-based HEPQ platform with an integrated scoring system provides a valid, user-friendly tool for assessing and interpreting healthy eating practices in preschool children. This platform supports parental engagement in children’s healthy eating practices and provides a practical tool for evaluating the effectiveness of nutrition education in early childcare settings.

Purpose:
Total hip arthroplasty (THA) is performed using various approaches, including posterior, lateral, and direct anterior approaches.The most beneficial method is controversial. Each approach has its advantages and disadvantages. This study compared patient satisfaction after bilateral THA using the direct anterior and lateral approaches on the same patient, considering the advantages and disadvantages of each approach.
Materials and Methods:
This study examined 30 patients who underwent bilateral THA: two with femoral neck fractures, 18 with osteonecrosis of the femoral head, six with borderline dysplasia-induced hip osteoarthritis, and four with degenerative hip osteoarthritis.Without distinguishing between the left and right sides, THA was performed randomly using the direct anterior approach on one side and the lateral approach on the other. The results of THA were compared using different approaches on the same patient, and patient satisfaction was evaluated.
Results:
Surgery using the direct anterior approach for THA showed favorable results in terms of the initial postoperative pain compared to surgery using the lateral approach. On the other hand, there was no significant difference observed after one month post-surgery. Among the participants, three preferred the direct anterior approach; four preferred the lateral approach, and 23 reported no preference.
Conclusion
In THA, the direct anterior approach may offer advantages in terms of initial postoperative pain and rehabilitation compared to the lateral approach. Nevertheless, the pain and joint function one month after surgery were similar between the two approaches.Therefore, the choice of approach should be determined by the surgeon's preference or experience, as both methods appear rational.

Nutrition Research and Practice 2025;19(6):985-1001
BACKGROUND/OBJECTIVES:
An illustrated questionnaire, the Healthy Eating Practice Questionnaire (HEPQ), was developed and validated to assess healthy eating practices among Korean preschool children.
SUBJECTS/METHODS:
The development process consisted of 4 phases: (1) item generation based on a literature review and focus group interviews, (2) item refinement through expert consultation, (3) illustration design, and (4) validation. One hundred and eighty-seven child–parent pairs and 24 teachers participated in the validation study. The reliability was examined using test–retest analysis, and the validity was assessed by comparing the children’s self-reports with those of their parents and teachers. The level of agreement was determined using the percentage agreement, kappa statistics, and intraclass correlation coefficient (ICC).
RESULTS:
The final 30-item questionnaire consisted of 4 domains: food preferences, eating behaviors, hand/oral hygiene practices, and nutrition knowledge. Most items showed a percentage agreement above 60% and kappa coefficients exceeding 0.5 in test–retest analysis, indicating acceptable consistency. The child–caregiver agreement was moderate to substantial, with kappa values generally above 0.4. The domain-level ICCs indicated good reliability (ICC = 0.49–0.83) and validity (ICC = 0.33–0.77) across all domains and subgroups.The comparisons by age showed that 4-yr-olds provided valid and reliable responses comparable to 5-yr-olds. The parents and teachers confirmed that the illustrated format was easy for the children to understand and complete independently.
CONCLUSION
The HEPQ showed satisfactory reliability and validity for assessing healthy eating practices among preschool children. The illustrated format enhances comprehension and engagement, supporting its applicability for research and nutrition education in daycare settings.

Clinical Psychopharmacology and Neuroscience 2025;23(4):683-706
Objective:
Since its development in 2002 by the Korean College of Neuropsychopharmacology and the Korean Society for Affective Disorders, the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) has undergone five revisions.
Methods:
To improve survey efficiency, reflect general clinical practice, and facilitate comparisons with previous KMAP-DD revisions, the overall structure of the questionnaire was retained. The six sections of the questionnaire were as follows:1) pharmacological treatment strategies for major depressive disorder with and without psychotic features; 2) pharmacological treatment strategies for persistent depressive disorder and other depressive disorder subtypes; 3) consensus on treatment-resistant depression; 4) selection of an antidepressant in consideration of safety, adverse effects, and comorbid physical conditions; 5) treatment strategies for special populations (children/adolescents, elderly, and women); and 6) non-pharmacological biological therapies. First-, second-, and third-line treatment recommendations were statistically derived.
Results:
Compared to KMAP-DD 2021, only minor changes were noted, due to the limited introduction of new medications or treatment modalities. Nonetheless, notable shifts included an increased preference for atypical antipsychotics (AAPs), and higher preference of combination strategies involving AAPs and mood stabilizers, indicating a more proactive and intensive treatment trend in Korea.
Conclusion
KMAP-DD is expected to serve as a valuable clinical resource by providing expert consensus-based recommendations on specific treatment strategies and pharmacological options for major depressive disorders, thereby supporting the integration of real-world clinical practice with evidence-based medicine.

Psychiatry Investigation 2024;21(1):28-36
Objective:
We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders.
Methods:
A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type. The most preferred value in each category in the total population was identified, and differences in the preference ratio of each item among the disease groups were compared.
Results:
A total of 707 participants were surveyed. In the total population, patients reported high efficacy (44.01%±21.44%) as the main wish for medication, themselves (37.39%±22.57%) and a doctor (35.27%±22.88%) as the main decision makers, and tablet/capsule (36.16%±30.69%) as the preferred type of drug. In the depressive disorders group, the preference ratio of high efficacy was significantly lower, and the preference ratio of a small amount was significantly higher than that of the psychotic disorder and bipolar disorder groups. The preference ratio of a doctor as an important decision maker in the bipolar disorder group was higher compared to the other groups.
Conclusion
This study revealed the preference for medications and showed differences among patients with psychiatric disorders. Providing personalized medicine that considers a patient’s preference for the drug may contribute to the improvement of drug compliance and outcomes.

Korean Journal of Community Nutrition 2023;28(3):206-219
Objectives:
Screen time refers to the time spent using screen media, such as televisions, smartphones, computers, or tablets. Excessive exposure to screen media has been reported to negatively impact young children’s health and development, including overweight, short sleep duration, and language delays. This study examined the association of screen time and mealtime media use with dietary behaviors among preschool children.
Methods:
A cross-sectional survey was conducted on parents of children aged three to five years using the online questionnaires of the Nutrition Quotient for Preschoolers (NQ-P) and the Dietary Screening Test (DST). Data from 261 children’s parents were analyzed.
Results:
Of the 261 children, 96.9% used screen media, 55.6% used screen media for two hours or more daily, and 30.7% were exposed to screen media during meals. The NQ-P scores were significantly lower in the children with longer screen time and mealtime media use. Children who used screen media for two hours or more and those exposed to screen media during meals consumed kimchi less frequently and confectionery and sugar-sweetened beverages more frequently than children who used less than two hours and were not exposed to screen media during meals. In addition, they were more likely to be picky about food, refuse to eat, and less likely to feed themselves than children with shorter screen time and no mealtime media use.
Conclusions
This study reported an association between unhealthy dietary behaviors, feeding difficulties, and screen time and mealtime media use among preschool children. Further research should explore effective strategies for reducing children’s screen time.

Clinical Psychopharmacology and Neuroscience 2023;21(1):188-196
Objective:
The Functioning Assessment Short Test (FAST) is a relatively specific test for bipolar disorders designed to assess the main functioning problems experienced by patients. This brief instrument includes 24 items assessing impairment or disability in 6 domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. It has already been translated into standardized versions in several languages. The aim of this study is to measure the validity and reliability of the Korean version of FAST (K-FAST).
Methods:
A total of 209 bipolar disorder patients were recruited from 14 centers in Korea. K-FAST, Young Mania Rating Scale (YMRS), Bipolar Depression Rating Scale (BDRS), Global Assessment of Functioning (GAF) and the World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF) were administered, and psychometric analysis of the K-FAST was conducted.
Results:
The internal consistency (Cronbach’s alpha) of the K-FAST was 0.95. Test-retest reliability analysis showed a strong correlation between the two measures assessed at a 1-week interval (ICC = 0.97; p < 0.001). The K-FAST exhibited significant correlations with GAF (r = −0.771), WHOQOL-BREF (r = −0.326), YMRS (r = 0.509) and BDRS (r = 0.598). A strong negative correlation with GAF pointed to a reasonable degree of concurrent validity. Although the exploratory factor analysis showed four factors, the confirmatory factor analysis of questionnaires had a good fit for a six factors model (CFI = 0.925; TLI = 0.912; RMSEA = 0.078).
Conclusion
The K-FAST has good psychometric properties, good internal consistency, and can be applicable and acceptable to the Korean context.

Background:
The association of myosteatosis measured using visual muscular quality map in computed tomography (CT) with nonalcoholic fatty liver disease (NAFLD), its severity, and fibrosis was analyzed in a large population.
Methods:
Subjects (n=13,452) with abdominal CT between 2012 and 2013 were measured total abdominal muscle area (TAMA) at L3 level. TAMA was segmented into intramuscular adipose tissue and skeletal muscle area (SMA), which was further classified into normal attenuation muscle area (NAMA) and low attenuation muscle area (LAMA). The following variables were adopted as indicators of myosteatosis: SMA/body mass index (BMI), NAMA/BMI, NAMA/TAMA, and LAMA/BMI. NAFLD and its severity were assessed by ultrasonography, and liver fibrosis was measured by calculating the NAFLD fibrosis score (NFS) and fibrosis-4 index (FIB-4) scores.
Results:
According to multiple logistic regression analyses, as quartiles of SMA/BMI, NAMA/BMI, and NAMA/TAMA increased, the odds ratios (ORs) for NAFLD decreased in each sex (P for trend <0.001 for all). The ORs of moderate/severe NAFLD were significantly higher in the Q1 group than in the Q4 group for SMA/BMI, NAMA/BMI, and NAMA/TAMA in men. The ORs of intermediate/high liver fibrosis scores assessed by NFS and FIB-4 scores increased linearly with decreasing quartiles for SMA/BMI, NAMA/BMI, and NAMA/TAMA in each sex (P for trend <0.001 for all). Conversely, the risk for NAFLD and fibrosis were positively associated with LAMA/BMI quartiles in each sex (P for trend <0.001 for all).
Conclusion
A higher proportion of good quality muscle was associated with lower risks of NAFLD and fibrosis.
