Development and psychometric analysis of the smombie scale for adolescents.

PURPOSE: Adolescent pedestrian accidents are increasing because of the "smombie" phenomenon, referring to pedestrians who are distracted by their smartphones and become unaware of their surroundings. In the field of nursing, this phenomenon can negatively affect adolescents' health and well-being. We developed the "smombie scale for adolescents" and examined its psychometric properties. DESIGN AND METHODS: We revised five items and the response scale of an existing smombie scale for adults based on cognitive interviews and content validity test, and included guiding descriptions for adolescents. Using the revised scale, we surveyed 430 adolescents from South Korea to assess construct validity through confirmatory factor analysis. To review group validity, a logistic regression was conducted using responses to the item on whether participants experienced accidents related to smartphone usage on the street or sidewalk. RESULTS: The 15 items in the four-factor structure, which was validated using confirmatory factor analysis, demonstrated: a chi-square value (p) of 232.63 (< 0.001), root mean square error of approximation of 0.06, goodness of fit index of 0.93, and Tucker-Lewis index of 0.94. The scale's Cronbach's α was 0.85, indicating good internal consistency. Logistic regression results considering actual accident occurrence showed that Factor 1 (perceived risk) and Factor 3 (pending instant message) were significantly correlated with smombie-related accidents. CONCLUSIONS: The smombie scale for adolescents demonstrated adequate construct and group validity, and good reliability. PRACTICE IMPLICATIONS: Its application can yield valuable insights into the effectiveness of pediatric nurses' educational and preventative efforts related to the smombie phenomenon in adolescents.

Development and psychometric properties of the social adjustment scale for youth cancer survivors in South Korea.

Objective: We developed a new scale-the Social Adjustment Scale for Youth Cancer Survivors-and examined its psychometric properties. Methods: In the scale's development stage, preliminary items were constructed based on the results of a concept analysis of the hybrid model, literature review, and interviews. These items were then reviewed through content validity and cognitive interviews. In the validation stage, 136 survivors were recruited from two children's cancer centers in Seoul, South Korea. An exploratory factor analysis was performed to identify a set of constructs, and validity and reliability were tested. Results: Starting with 70 items constructed through literature review and interviews with youth survivors, the final scale comprised 32 items. The exploratory factor analysis identified four domains-namely, role achievement in one's present position, harmony in relationships, disclosure and acceptance of cancer history, and preparation and expectation for future roles. Correlations with quality of life indicated good convergent validity (r â€‹= â€‹0.82, P â€‹< â€‹0.001). The Cronbach's α of the overall scale was 0.95, indicating excellent internal consistency; and the intraclass correlation coefficient was 0.94 (P â€‹< â€‹0.001), suggesting high test-retest reliability. Conclusions: The Social Adjustment Scale for Youth Cancer Survivors exhibited acceptable psychometric properties in measuring the social adjustment of youth cancer survivors. It can be used to identify youths facing difficulty in adjusting to society after treatment and to investigate the effect of interventions implemented to promote social adjustment among youth cancer survivors. Future research is needed to examine the applicability of the scale in patients across diverse cultural backgrounds and healthcare systems.

The relationships of perceived susceptibility, perceived severity, and subjective norms with COVID-19 preventive behaviors: a secondary data analysis comparing adolescents and emerging adults in South Korea.

PURPOSE: Based on the health belief model and theory of planned behavior, this study investigated how age group (adolescence and emerging adulthood) moderated the relative effects of perceived susceptibility, perceived severity, and subjective norms on preventive behavior against coronavirus disease 2019 (COVID-19). METHODS: This secondary data analysis utilized data from adolescents (n=272) and emerging adults (n=239). Hierarchical multiple regression analysis was performed to test the moderating effect of age group on the relationships among variables. RESULTS: Higher perceived susceptibility (ß=.21, p<.001), perceived severity (ß=.14, p=.002), subjective norms (friends) (ß=.26, p<.001), subjective norms (parents) (ß=.44, p<.001), and subjective norms (schools) (ß=.28, p<.001) enhanced COVID-19 preventive behaviors. Moderated regression analysis showed that subjective norms (friends and school) impacted preventive behavior in adolescents more than in emerging adults. CONCLUSION: Given the need to increase perceived susceptibility and severity among adolescents and emerging adults, these findings provide baseline data for designing effective COVID-19 prevention interventions that consider the developmental characteristics of different age groups. Interventions by health centers at universities can strengthen COVID-19 preventive behavior among emerging adults. As adolescents are influenced by friends, their peer roles must be strengthened to enhance adherence to COVID-19 preventive guidelines.

Smartphone Usage Patterns and Their Physical, Psychological, and Cyber-Behavioral Predictors Among Adolescents in South Korea.

BACKGROUND: Adolescents are described as digital natives, with smartphones deeply embedded in their lives. However, limited literature on smartphone usage patterns exists. This study examined adolescents' smartphone usage patterns and their physical, psychosocial, and cyber-behavioral profiles. METHODS: We used latent profile analysis and a person-centered approach to investigate 11 items on smartphone use purpose and use time. Participants were 2324 first-year middle-school students (aged 13 years) from a nationally representative dataset. RESULTS: Four distinct profile groups were observed: minimalist users, entertainment users, social users, and multifunctional users. The 4 profiles differed by gender and physical (physical activity and obesity), psychosocial (relationships with their parents, depression, and academic lethargy), and cyber-behavioral (smartphone use time, computer use time, and cyber delinquency) status. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Our findings have key research and real-world implications for developmental psychologists and school health providers, specifically for those who work with adolescents, to address concerns regarding adolescents' smartphone use. CONCLUSIONS: Adolescents use smartphones at varying times and for various purposes. A better understanding of adolescents' smartphone usage and purposes can help parents and school health providers develop and implement interventions.

The effectiveness of home visiting programs for the prevention of child maltreatment recurrence at home: a systematic review and meta-analysis.

PURPOSE: This systematic review aimed to investigate the effectiveness of home visiting programs targeting parents who have maltreated their children on the prevention of child maltreatment recurrence. METHODS: Major databases were searched (Ovid-Medline, PubMed, Cochrane Library, CINAHL, and RISS). The frequency of maltreatment was measured for the meta-analysis, which was conducted using Review Manager 5.2 software. The effect size was measured using odds ratios (ORs). RESULTS: Six studies were included in the analysis, none of which were conducted in South Korea. The meta-analysis demonstrated that the risk of child maltreatment recurrence significantly decreased after a home visiting program was implemented (OR=0.45, 95% confidence interval [CI]=0.29-0.68). Nurses were the most common intervention providers. CONCLUSION: Home visiting programs should be provided for families in which maltreatment has already occurred to prevent the recurrence of maltreatment and foster a home environment in which children can live safely. Since the rate of child maltreatment in Korea is increasing, further research is needed to develop and implement home visiting programs in which nurses play a major role in preventing the recurrence of child maltreatment.

Factors associated with preventive behaviors for COVID-19 among adolescents in South Korea.

PURPOSE: COVID-19's infection rate among adolescents is increasing; hence, it is important to prevent it as it can spread in the community through transmission in schools. It is crucial to determine the extent to which adolescents follow COVID-19 preventive measures and identify factors relating to such behaviors to implement more effective health education. This study aimed to understand factors related to COVID-19 preventive behaviors using the theory of planned behavior (TPB) and the health belief model (HBM) among adolescents in South Korea. DESIGN AND METHODS: A cross-sectional face-to-face questionnaire survey was conducted among 272 adolescents in South Korea. Structural equation modeling was used to examine the relationships between perceived susceptibility, perceived severity, attitude, subjective norms, perceived behavioral control, intention, and COVID-19 preventive behaviors. RESULTS: Among adolescents' COVID-19 preventive behavior scores, wearing masks was the highest and distancing was the lowest. Adolescents' adherence to COVID-19 preventive behaviors was directly or indirectly associated with their perceived susceptibility, perceived severity, subjective norms, perceived behavioral control, and intention. CONCLUSIONS: Attention to mitigate social isolation is important to improve compliance with COVID-19 preventive behaviors. Perceived susceptibility, perceived severity, subjective norms, perceived behavioral control, and intention explained 61.3% of adolescents' COVID-19 preventive behaviors, there is a need for education to promote relevant factors. PRACTICE IMPLICATIONS: To increase adolescent awareness of COVID-19 and increase attitudes, subjective norms, and perceived behavior control, nurses need to provide education including the evidence for COVID-19 preventive behavior to increase adolescents' understanding and active implementation of those behaviors.

[Bereavement Care for Parents in the Neonatal Intensive Care Unit: A Literature Review]. / ì‹ ìƒì•„ 집중치료실 기반 사별 간호의 ë¬¸í—Œê³ ì°°.

PURPOSE: The purpose of this study was to review studies investigating the effect of bereavement care provided for parents in the neonatal intensive care unit. METHODS: We conducted a literature review of databases (MEDLINE, Embase, Cochrane Library, and CINAHL) for studies published in English and four databases (RISS, KISS, NANET, and KoreaMed) for Korean studies. The selection criteria included original articles that evaluated the parents' perceptions or responses to bereavement care provided in the neonatal intensive care unit. Of 889 articles from the initial screening, 66 articles underwent full-text review and five articles were finally selected for analysis. RESULTS: None of the studies was conducted in Korea. Only one study used a randomized control trial design. The forms of bereavement care reviewed included a provision of a memory package, grief information, and emotional and/or social support from peers or health care providers. The effectiveness of bereavement care was measured by including grief, social support, and depression. CONCLUSION: Bereavement care can be considered to be beneficial for relieving grief reactions and enhancing the personal growth of bereaved parents. Future research should assess the needs of bereaved parents in Korea. Nurses may play a role in developing the bereavement care for parents.

Social Adjustment of Adolescent Cancer Survivors: A Concept Analysis.

PURPOSE: This study aimed to identify the attributes of social adjustment among adolescent cancer survivors using concept analysis and to propose a definition of the concept. METHODS: In accordance with the hybrid model of concept analysis, this study employed a three-phase circular process comprising theoretical, fieldwork, and final analysis phases. A thorough literature review was conducted using MEDLINE, Embase, and Korean databases, followed by qualitative fieldwork with seven participants. The results derived from the theoretical and fieldwork phases were integrated into the final analysis phase. RESULTS: Four attributes of social adjustment were found in adolescent cancer survivors: having harmonious relationships with friends, having harmonious relationships with boy/girlfriends, fulfilling their present roles, and planning for and expecting future roles. The following definition of social adjustment of adolescent cancer survivors is proposed: "the conquering of difficulties arising from the continuum of childhood cancer and the achievement of the developmental tasks of typical adolescents." CONCLUSION: Social adjustment of childhood cancer survivors is crucial for integrating them into society. The findings of this study provide a basis for developing an instrument to measure the social adjustment of adolescent cancer survivors and for developing of interventions that target this group.

Oxidative stability of extracts from red ginseng and puffed red ginseng in bulk oil or oil-in-water emulsion matrix.

BACKGROUND: Explosive puffing can induce changes in the chemical, nutritional, and sensory quality of red ginseng. The antioxidant properties of ethanolic extracts of red ginseng and puffed red ginseng were determined in bulk oil and oil-in-water (O/W) emulsions. METHODS: Bulk oils were heated at 60°C and 100°C and O/W emulsions were treated under riboflavin photosensitization. In vitro antioxidant assays, including 2,2-diphenyl-1-picrylhudrazyl, 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid, ferric reducing antioxidant power, total phenolic content, and total flavonoid content, were also performed. RESULTS: The total ginsenoside contents of ethanolic extract from red ginseng and puffed red ginseng were 42.33 mg/g and 49.22 mg/g, respectively. All results from above in vitro antioxidant assays revealed that extracts of puffed red ginseng had significantly higher antioxidant capacities than those of red ginseng (p < 0.05). Generally, extracts of puffed red and red ginseng had high antioxidant properties in riboflavin photosensitized O/W emulsions. However, in bulk oil systems, extracts of puffed red and red ginseng inhibited or accelerated rates of lipid oxidation, depending on treatment temperature and the type of assay used. CONCLUSION: Although ethanolic extracts of puffed red ginseng showed stronger antioxidant capacities than those of red ginseng when in vitro assays were used, more pro-oxidant properties were observed in bulk oils and O/W emulsions.

Mobile Technology in Undergraduate Nursing Education: A Systematic Review.

OBJECTIVES: This study aimed to identify and systematically review the literature on the use of mobile technology in nursing education. The research findings could evidence the effectiveness of mobile technology in undergraduate nursing students' learning outcomes. METHODS: Computerized searches were conducted using the Ovid-MEDLINE, Ovid-EMBASE, Cochrane Library, and CINAHL databases for relevant primary studies and limited to those between 2000 and February 2018. Only randomized controlled trials (RCTs) and quasi-experimental studies published in either English or Korean were included and critically appraised using Joanna Briggs Institute tools. RESULTS: Seven RCTs and 7 quasi-experimental studies were identified. The mobile device and intervention applied varied throughout all the studies. Studies published earlier in the 2000s found that immediate access to clinical and pharmacological referencing information through the mobile device increased students' efficacy in clinical practice. Later studies, which were mostly conducted in Korea, reported that smartphone-based applications could promote nursing students' learning motivation and satisfaction but not their clinical skills and knowledge. CONCLUSIONS: We still seem to be in the beginning stage of implementing mobile technology in nursing education due to the limited implication of mobile technology and inconsistent research conclusions. In the future, rigorous primary empirical studies are needed to suggest the effective use of mobile devices in nursing education.

Effects of α-tocopherol on the oxidative stability and incorporation of deuterium in volatiles from a linoleic acid-deuterium model system.

The effects of α-tocopherol on the oxidative stability and incorporation of deuterium in volatiles were evaluated in linoleic acid-water model systems treated at 60°C by analyzing headspace oxygen depletion, formation of lipid hydroperoxides, and profiles of headspace volatiles. Deuterium oxide accelerated the rates of linoleic acid oxidation compared to samples in deuterium-free water. As the concentration of α-tocopherol increased from 0 to 1500 ppm, the consumption of headspace oxygen and the formation of volatiles decreased, whereas the contents of lipid hydroperoxides did not decrease in the linoleic acid-water system. The mass to charge ratios (m/z) of volatiles in linoleic aciddeuterium oxide were significantly higher than those with deuterium oxide-free water. Generally, the presence of α-tocopherol decreased the mass to charge ratios (m/z) of volatiles including pentanal, hexanal, t-2-heptenal, and 2-octenal, implying that α-tocopherol may be involved in the aldehyde formation from lipid oxidation.

Antioxidant Properties of Aqueous Extract of Roasted Hulled Barley in Bulk Oil or Oil-in-Water Emulsion Matrix.

UNLABELLED: Antioxidant properties of the aqueous extracts of hulled barley (Hordeum vulgare L.) that had been roasted at 210 °C for 20 min were determined in bulk oil and oil-in-water (O/W) emulsions. Bulk oils were heated at 60, 100, and 180 °C, and O/W emulsions were oxidized under riboflavin photosensitization. The content of phenolic compounds was analyzed by high-performance liquid chromatography, and in vitro antioxidant assays were also conducted. The major phenolics contained in the aqueous extract of roasted hulled barley (AERB) were p-coumaric, ferulic, protocatechuic, chlorogenic, 4-hydroxybenzoic, and vanillic acids. Depending on the concentration and oxidation temperature, AERB had antioxidant or prooxidant properties in bulk oil. At 60 °C, AERB at a concentration of 0.5% acted as a prooxidant, whereas at 1.0% it acted as an antioxidant. At 100 °C, AERB acted as an antioxidant irrespective of concentration. In 180 °C conditions, 0.5% AERB acted as a prooxidant, whereas other concentrations of AERB acted as antioxidants. In the case of riboflavin photosensitized O/W emulsions, AERB showed antioxidant properties irrespective of concentration. Antioxidant abilities of AERB are affected by the food matrix, including bulk oil and O/W emulsions, and concentrations of AERB, even though diverse phenolic compounds may display high antioxidant properties in in vitro assays. PRACTICAL APPLICATION: Roasted barley has been widely used as a tea ingredient in East Asian countries such as Korea, China, and Japan. The highly antioxidative properties of the aqueous extracts of roasted barley have been confirmed in bulk oil and O/W emulsions as well as in vitro assays because of the presence of phenolic compounds. The results of this study can contribute to the development of antioxidant-rich beverages using roasted barley by aiding in the selection of proper food matrix-containing extracts of high phenolic compounds, as well as by expanding consumers' choices for healthy beverages.

Antioxidant properties of ascorbic acid in bulk oils at different relative humidity.

The effects of relative humidity (RH) on the antioxidant properties of ascorbic acid (10, 20, 42, and 84ppm) were investigated in stripped corn oils stored at 60°C. The degree of oxidation in oils was determined by analysing headspace oxygen content and conjugated dienoic acids. The oxidative stability of bulk oils without addition of ascorbic acid was significantly different depending on the RH. As the concentration of ascorbic acid increased from 10 to 84ppm, oxidative stability increased significantly irrespective of RH (p<0.05). Generally, oils containing ascorbic acid at low RH had higher oxidative stability after storage at 60°C than those at high RH. The antioxidant properties of ascorbic acid were greatly influenced by both the moisture content in the oil and the ascorbic acid concentration.

Effects of relative humidity on the antioxidant properties of α-tocopherol in stripped corn oil.

The effects of relative humidity (RH) on the antioxidant properties of α-tocopherol (10, 20, 42, and 84 ppm) were determined in stripped corn oil oxidised at 60°C. The degree of oxidation in oils was determined by analysing headspace oxygen content and conjugated dienoic acids (CDAs). Changes in moisture and α-tocopherol content were also monitored. The oxidative stability of stripped corn oil and stability of α-tocopherol differed significantly depending on the RH. As the concentration of α-tocopherol increased from 10 to 84 ppm, oxidative stability decreased significantly irrespective of RH. The remaining α-tocopherol content decreased as RH increased, suggesting an important role for moisture content in the stability of α-tocopherol. Antioxidant properties of α-tocopherol were greatly influenced by both moisture content in oil and α-tocopherol concentration.
