Development of nursing handoff competency scale: a methodological study

BACKGROUND

Nursing handoff competency is the ability of the nurse performing the handoff to select and interpret the necessary information for patient care and to convey it efficiently to the nurse accepting the handoff. Nursing handoff is an important nursing task that ensures nursing care continuity, quality and patient safety. This study aimed to develop a scale to measure nursing handoff competency and verify its validity and reliability.

METHODS

This study adopted a methodological design. A research process included three phases: (1) scale development (literature review and interviews); (2) scale validation (validity and reliability); (3) standard setting. Data were collected from 496 clinical nurses currently working in hospital wards, intensive care units, and emergency rooms, and who independently perform a handoff in South Korea.

RESULTS

The final scale comprises a self-reported 4-points Ilert scale with 25 items based on four factors: knowledge on handoff methods, identification of patient information, judgment and transfer of nursing situation, and "formation of supportive relationships. Construct validity, criterion-related validity, and discrimination validities were verified and the fitness of the scale revealed good results in confirmatory factor analysis. The Cronbach's α of the whole tool was.912 and the cut-off score for satisfied/unsatisfied was.72.

CONCLUSIONS

The developed scale can evaluate the nurse's handoff competencies and determine whether training is necessary. The measurement results of the scale can be used to select training subjects and compose the contents of the education program.

Evaluation of the reliability and validity of the health regulatory focus scale in Chinese samples

This study sought to validate the psychometric properties of the Health Regulatory Focus Scale (HRFS), emphasizing its manifestation and association with personality traits in a Chinese context. Originally developed by Ferrer, the HRFS gauges individuals' inclinations either to avoid negative health outcomes (prevention focus) or achieve positive health outcomes (promotion focus). Our cross-sectional analysis involved a diverse sample of 652 Chinese participants, averaging 39.6 years in age (SD = 9.39). Data were analyzed using SPSS and AMOS, and both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were employed to assess the HRFS's factor structure. Additionally, we evaluated convergent and discriminant validity, criterion-related validity, internal consistency reliability, and test-retest reliability. The CFA results (CFI = 0.985, TLI = 0.971, RMSEA = 0.059, and SRMR = 0.047), combined with McDonald's omega value (0.916) and the test-retest correlation coefficient (0.78) for the HRFS, underscore its robust construct validity and reliability. Furthermore, the promotion dimension of the HRFS exhibited significant positive correlations with all dimensions of the Chinese Adjectives Short Scale of Big-Five Factor Personality (BFFP-CAS-S). In conclusion, the HRFS's Chinese adaptation offers a reliable and valid instrument for assessing health regulatory focus.

Validation of the Korean Version of Patient-Centered Care Tool: For Outpatients

Aim

The objective of this study was to assess the validity and reliability of the Korean version of the patient-centered care (K-PCC) instrument for outpatients. The study was conducted due to the absence of a measurement tool specifically designed to evaluate patient-centered care for outpatients.

Design

This study is a methodological study to verify the validity and reliability of the Korean version of Patient-Centered Care (K-PCC) to measure patient-centeredness for outpatients.

Methods

As a first step for the evaluation of the tool, the content validity was verified by expert panel. Then, a total of 400 outpatients were recruited, and construct validity was verified through confirmatory factor analysis (CFA) as the second step for the evaluation of the tool. The convergent and discriminant validity of the tool was verified by calculating the standardized factor loads, construct reliability (CR), and average variance extracted (AVE), and calculating the correlation square between the factors as the third and fourth steps for the evaluation of the tool. And as a fifth step for the evaluation of the tool, criterion validity was evaluated by comparing the correlation with the patient-centeredness measurement tool for inpatients (PEx-inpatient). In estimating reliability, internal consistency reliability coefficients were calculated.

Results

The confirmatory factor analysis supported good fit for the Korean patient-centered care instrument (K-PCC), and the eight-factor structure was validated. The scale comprises 21 items across eight factors: patient preferences (4 items), physical comfort (2 items), coordination of care (2 items), continuity and transition (3 items), emotional support (2 items), access to medical care (3 items), information and education (2 items), and family and friends (3 items). The Cronbach's alphas ranging between 0.73 and 0.88.

Conclusion

The Korean patient-centered primary care instrument is a valid and reliable scale to measure patient-centered care for outpatients in the Korean medical environment.

[Psychometric Properties of the Korean Version of Self-Efficacy for HIV Disease Management Skills]

PURPOSE

This study evaluated the validity and reliability of Shively and colleagues' self-efficacy for HIV disease management skills (HIV-SE) among Korean participants.

METHODS

The original HIV-SE questionnaire, comprising 34 items, was translated into Korean using a translation and back-translation process. To enhance clarity and eliminate redundancy, the author and expert committee engaged in multiple discussions and integrated two items with similar meanings into a single item. Further, four HIV nurse experts tested content validity. Survey data were collected from 227 individuals diagnosed with HIV from five Korean hospitals. Construct validity was verified through confirmatory factor analysis. Criterion validity was evaluated using Pearson's correlation coefficients with the new general self-efficacy scale. Internal consistency reliability and test-retest were examined for reliability.

RESULTS

The Korean version of HIV-SE (K-HIV-SE) comprises 33 items across six domains: "managing depression/mood," "managing medications," "managing symptoms," "communicating with a healthcare provider," "getting support/help," and "managing fatigue." The fitness of the modified model was acceptable (minimum value of the discrepancy function/degree of freedom = 2.49, root mean square error of approximation = .08, goodness-of-fit index = .76, adjusted goodness-of-fit index = .71, Tucker-Lewis index = .84, and comparative fit index = .86). The internal consistency reliability (Cronbach's α = .91) and test-retest reliability (intraclass correlation coefficient = .73) were good. The criterion validity of the K-HIV-SE was .59 (p < .001).

CONCLUSION

This study suggests that the K-HIV-SE is useful for efficiently assessing self-efficacy for HIV disease management.

Impact of pressure ulcer prevention knowledge and attitude on the care performance of long-term care facility care workers: a cross-sectional multicenter study

BACKGROUND

The Long-Term Care Insurance Act in the Republic of Korea has enabled the elderly population to receive benefits through the long-term care system since July 2008. Because one nurse or nursing assistant is assigned to 25 elderly persons and one care worker is assigned to 2.5 elderly persons in long-term care facilities, registered nurses should educate care workers to participate in pressure ulcer prevention activities. This descriptive study investigated the effect of the knowledge and attitude related to pressure ulcer prevention on care performance.

METHODS

Data were collected from February 20 to December 15, 2021 using a structured questionnaire targeting 165 care workers in four long-term care facilities located in I-city and Y-gun, Gyeongsangbuk-do. The questionnaires of the knowledge, attitude, and care performance developed for nurses were modified to survey the care workers. The content validity was verified on a 4-point scale by 10 clinical experts. A preliminary survey was conducted for 30 care workers, and the contents of the modified questionnaire were further revised. Data analyses were performed by t-test, one-way ANOVA, Scheffé test, Pearson's correlation coefficient, and a multiple linear regression modeling using the SPSS/WIN 25.0 program.

RESULTS

Care performance on pressure ulcer prevention had a significant positive correlation with knowledge (r = 0.692, p < .001), attitude (r = 0.426, p < .001), work experience (r = 0.760, p < .001), amount of experience (r = 0.712, p < .001), and the number of training sessions received (r = 0.551, p < .001). In multiple regression modeling, work experience (β [standardized coefficient beta] = 0.534, p = .000), knowledge (β = 0.323, p = .000), and attitude (β = 0.103, p = .049) related to pressure ulcer prevention were identified as variables significantly affecting care performance. The regression model explained 65.4% with 5 independent variables.

CONCLUSION

To prevent bedsores in long-term care facilities, it is necessary to educate care workers regularly about pressure ulcer prevention. In addition, clinical guidelines could help standardize the pressure ulcer prevention work of caregivers, strongly regulating their practice in all long-term care facilities and monitoring bedsore prevention regularly.

Validating the use of the Wijma Delivery Expectancy/Experience Questionnaire in Mainland China: a descriptive, cross-sectional study

BACKGROUND

Fear of childbirth (FOC) is a common psychological problem in Chinese pregnant women. FOC can influence both maternal health and infants' wellness. Special assessment tools for FOC in Mandarin Chinese are currently lacking. The aim of this study was to evaluate the psychometric properties of the Mandarin Chinese of the Wijma Delivery Expectancy/Experience Questionnaire Version A (W-DEQ-A).

METHODS

We recruited 364 Chinese pregnant women from April 2021 to July 2021. Translation and cultural adaptation, as well as reliability and validity testing were conducted. Analyses included the content validity, structural validity, criterion-related validity, convergent validity and reliability. The content validity indices were used to assess the content validity of the tool. The structural validity was tested through exploratory factor analysis and confirmatory factor analysis. The Cronbach's alpha coefficient was used to evaluate the reliability of the W-DEQ-A Chinese version.

RESULTS

The Chinese translation showed excellent similarities and equivalence to the original version, with the satisfactory content validity. Factor analysis indicated 5 factors, accounting for 57% of the total variance. Both criterion-related validity and convergent validity proved to be acceptable. The reliability was tested with a Cronbach's alpha coefficient of 0.911 for the total scale.

CONCLUSION

The W-DEQ-A Chinese version is a reliable and valid tool to identify FOC in Mandarin Chinese-speaking populations.

[The Validity and Reliability of the Korean Version of Readiness for Practice Survey for Nursing Students]

PURPOSE

This study aimed to evaluate the validity and reliability of the Korean version of the Readiness for Practice Survey (K-RPS).

METHOD

The English Readiness for Practice Survey was translated into Korean using the Translation, Review, Adjudication, Pretesting, and Documentation (TRAPD) method. Secondary data analysis was performed using the dataset from the New Nurse e-Cohort study (Panel 2020) in South Korea. This study used a nationally representative sample of 812 senior nursing students. Exploratory and confirmatory factor analyses were also conducted. Convergent validity within the items and discriminant validity between factors were assessed to evaluate construct validity. Construct validity for hypothesis testing was evaluated using convergent and discriminant validity. Ordinary α was used to assess reliability.

RESULTS

The K-RPS comprises 20 items examining four factors: clinical problem solving, learning experience, professional responsibilities, and professional preparation. Although the convergent validity of the items was successfully verified, discriminant validity between the factors was not. The K-RPS construct validity was verified using a bi-factor model (CMIN/DF 2.20, RMSEA .06, TLI .97, CFI .97, and PGFI .59). The K-RPS was significantly correlated with self-esteem (r = .43, p < .001) and anxiety about clinical practicum (r = -.50, p < .001). Internal consistency was reliable based on an ordinary α of .88.

CONCLUSION

The K-RPS is both valid and reliable and can be used as a standardized Korean version of the Readiness for Practice measurement tool.

Translation and Psychometric Evaluation of the Female Sexual Resourcefulness Scale (FSRS) in South Korea

Women have less control over decisions about risky sexual behavior and condom use than men. This power imbalance makes women vulnerable when having sexual relationships with their partner. However, no measurement tool has been developed to measure female sexual resourcefulness, which measures women's self-perceived sexual right to self-determination. This study examined the psychometric properties of the Korean version of the female sexual resourcefulness scale (FSRS). Convenience sampling was conducted using social networking services. The participants were 217 women in their early 20s. Validity and reliability were examined using item analysis, factor analysis, and correlation with self-efficacy on condom use and self-efficacy in refusing sex, and Cronbach's alpha. Twelve items were selected for the study. Three factors were extracted through factor analysis, explaining 62.03% of the variance and showing a good model fit in the K-FSRS. Reliability was high, as indicated by a Cronbach's alpha of 0.85. These results indicate that the K-FSRS may be an appropriate instrument for measuring sexual resourcefulness among young Korean women.

Psychometric Properties of the Korean Version of the Environmental Health Literacy Scale

The environmental health literacy (EHL) scale evaluates media-specific and general EHL levels in three domains: knowledge, attitude, and behavior. This study aimed to adapt the EHL scale developed by Lichtveld et al. into the Korean language (K-EHL scale) and to verify its reliability and validity. Survey data was collected from 492 adults (19-65 years) residing in Korea. The study process included translation procedures, content validity verification, pre-testing, the actual survey, and statistical analysis for validation and selection of the final items. The scale-level content validity index was 0.92, and one item was removed. Multiple exploratory factor analyses condensed the K-EHL into 2 factors and 38 items. The "Environmental health knowledge and attitude" factor (14 items) measures information, feelings, and thoughts about environmental health. The "Environmental health behavior" factor (24 items) comprises behaviors responding to environmental health. A construct validity (criterion and discriminant validity) was verified using confirmatory factor analysis for goodness of fit (CFI = 0.901, TLI = 0.863, GFI = 0.923, NFI = 0.862, and RMSEA = 0.08). Internal consistency reliability test results showed a Cronbach's α of 0.81 for the total items. This study is the first to introduce the EHL in Korea, and it also presents a validated evaluation tool. The K-EHL is expected to elucidate EHL levels in Korea. In the future, the EHL scale can be enhanced using this tool.

Development of Critical Reflection Competency Scale for Clinical Nurses

Critical reflection develops nurses' critical thinking and clinical reasoning competency. It is necessary to develop a validated scale to measure critical reflection competency considering the clinical situation and nursing context. Therefore, this study analyzed the concept of critical reflection, developed a scale to measure critical reflection competency, and verified its validity and reliability. The concept of critical reflection and components of the scale were confirmed through literature review and results of previous studies on content analysis. A total of 64 preliminary items were derived on a 5-point Likert scale. The adequacy of vocabulary and expression was checked, and a content validity test was conducted. An I-CVI value of 0.88-1.00 was computed. Construct validity was conducted through an exploratory factor analysis, and data collected from 296 clinical nurses were analyzed. Five factors and nineteen items were derived, and the explanatory power was found to be 53.02%. Cronbach's α of the scale was 0.853. Future studies need to develop a critical reflection education program and utilize this concept as an educational strategy. We propose a study to verify the effect of applying an educational program using the critical reflection competency scale developed in this study.

The Development and Validation of a Perceived Nursing Support Scale for Mothers of Preterm Infants

PURPOSE

Many studies have maintained that nursing support is necessary and essential for mothers of preterm infants; however, the perceived nursing support for mothers of preterm infants has not been sufficiently measured. This study aimed to develop a perceived nursing support scale for mothers of preterm infants (PNSS-MP).

METHODS

The preliminary items of the PNSS-MP were developed through a literature review and in-depth interviews with mothers of preterm infants. Content validity and face validity were assessed by experts and mothers of preterm infants. A pilot study was conducted to confirm the feasibility and comprehension of the scale. To validate the PNSS-MP, 223 mothers of preterm infants were surveyed. Exploratory factor analyses were performed to confirm construct validity. Convergent and discriminant validity were analyzed using a multitrait-multimethod (MTMM) matrix. Reliability was tested by calculating Cronbach's alpha and performing split-half testing.

RESULTS

The PNSS-MP consisted of 27 items and was categorized into five factors, explaining 65.27% of the total variance. The factors were named: "baby care support" (7 items), "mental care support" (6 items), "maternal role support" (6 items), "introducing resources support" (4 items), and "information delivery support" (4 items). The overall reliability of the scale was .95.

CONCLUSION

The PNSS-MP adequately reflected the neonatal intensive care unit (NICU) in South Korea. Additionally, the PNSS-MP proved relatively valid and reliable; therefore, it can be used to measure nursing support in the NICU.

The Psychological Responses of Nurses Caring for COVID-19 Patients: A Q Methodological Approach

Anxiety among nurses attending patients at the forefront of the global coronavirus disease-19 (COVID-19) pandemic is on the rise. Accordingly, examining the psychological response of nurses who have attended COVID-19 patients is necessary. This study aimed to categorize and characterize the psychological responses of nurses who have experienced COVID-19 patient care based on the Q methodology. The Q-sample extracted 34 statements, and the P-sample marked 22 nurses who had operated a screening clinic and experienced patient care in the local base hospitals treating COVID-19 using convenience sampling. The findings suggest that nurses who have experienced COVID-19 patient care fall into three categories based on the following psychological responses: (1) fear of social stigma, (2) anxiety about the risk of infection, and (3) burden of infection prevention and control nursing. Therefore, it is expected that the results of this study may serve as the basis for emotional support programs that are capable of understanding and mediating the psychological state of nurses who care for patients with COVID-19.

Validation of the Korean Version of the Nursing Profession Self-Efficacy Scale: A Methodological Study

Background: The Nursing Profession Self-Efficacy (NPSE) scale was developed to reflect the characteristics of nursing tasks. This study was conducted to validate the Korean version of the NPSE (K-NPSE) scale. Methods: The NPSE scale with nineteen items was translated into Korean after forward and backward translation according to Devellis’ guideline. For the exploratory factor analysis (EFA), 298 nurses participated and criterion-related validity and reliability were verified. For the confirmatory factor analysis (CFA), 218 other nurses participated. Content validity, criterion-related validity, and internal consistency reliability were examined. Additionally, construct validity was examined. SPSS and AMOS were used for the data analyses. Results: Nineteen items were selected after evaluating the content and cognitive validity and comprised three factors: “Professional (10 items)”, “Advocating (4)”, and “Caring (5)”. Construct validity was supported by the CFA. Criterion-related validity was supported by comparison with the General Self-Efficacy Test (r = 0.43, p < 0.001). Cronbach’s alpha of the K-NPSE was 0.93. Conclusions: Study findings indicate that the K-NPSE could be useful for assessing nurses’ self-efficacy. The K-NPSE may be used as a valuable reference for developing programs or policies that promote nursing professionals. It is expected that continued use of this scale in various clinical settings to further generalize and validate the scale.

Development and validation of a self-control competency scale for late-school-aged children

Purpose

The aim of this study was to develop a self-control competency scale for school-aged children and to confirm its reliability and validity.

Methods

This study involved methodological research to verify the reliability and validity of a self-control competency scale for school-aged children. Data were collected from 438 students in the fifth and sixth grades of elementary school.

Results

The self-control competency scale was composed of 13 items and six subscales (control of relationship with one’s teacher, problem-solving, peer empathy, control of relationships with one’s peers, impulse control, and emotional control). The internal consistency reliability of the scale was evaluated using Cronbach’s α, which was .83 for the entire scale and ranged from .65 to .76 for the subscales. The model of six subscales was validated by CFA (CMIN/df=1.977; p<.001, GFI=.94, SRMR=.050, RMSEA=.065, IFI=.95, TLI=.93, CFI=.95). Concurrent validity was evaluated by comparing this scale to the scale developed by Nam and Ok (2000), and a significant correlation was found (r=.82, p<.001). On this scale, higher scores indicate higher levels of self-control among late-school-aged children.

Conclusion

This scale can be used as a valid and reliable instrument for examining self-control competency among late-school-aged children.

[Reliability and Validity of Korean Version of Nursing Students' Anxiety and Self-Confidence with Clinical Decision Making Scale]

PURPOSE

The purpose of this study was to adapt, modify, and validate the Nursing Anxiety and Self-Confidence with Clinical Decision-Making Scale (NASC-CDM©) for Korean nursing students.

METHODS

Participants were 183 nursing students with clinical practice experience in two nursing colleges. The construct validity and reliability of the final Korean version of the NASC-CDM© were examined using exploratory and confirmatory factor analyses and testing of internal consistency reliability. For adaptation and modification, the instrument was translated from English to Korean. Expert review and a cross-sectional survey were used to test the instrument's validity.

RESULTS

The Korean version of the NASC-CDM© (KNASC-CDM) was composed of 23 items divided into four dimensions: (i) Listening fully and using resources to gather information; (ii) Using information to see the big picture; (iii) Knowing and acting; and (iv) Seeking information from clinical instructors. The instrument explained 60.1% of the total variance for self-confidence and 63.1% of the variance for anxiety; Cronbach's α was .93 for self-confidence and .95 for anxiety.

CONCLUSION

The KNASC-CDM can be used to identify anxiety and self-confidence in nursing students' clinical decision-making in Korea. However, further research should be done to test this instrument, as it is classified differently from the original NASC-CDM© version.

Translation and validation of the Korean version of the Diabetic Foot Ulcer Scale-Short Form

The purpose of this study was to translate the Diabetic Foot Ulcer Scale-Short Form (DFS-SF) into Korean and evaluate its psychometric performance in patients with diabetic foot ulcers (DFUs). The DFS-SF was translated into Korean using translation guidelines from the World Health Organization. The Korean version of DFS-SF (DFS-SF-K) went through the full linguistic validation process and was evaluated in 320 Korean patients with DFU. For this study, Cronbach's alpha was used to evaluate the reliability of the DFS-SF-K. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and known-group validity were conducted to examine construct validity. Correlation of the DFS-SF-K with SF-36 was used to test concurrent validity of the DFS-SF-K. Cronbach's alpha was >0.70 for all scales. Factor loadings of the 29 items on the six subscales ranged from 0.82 to 0.95. The six-subscale model was validated by CFA (x² /df = 4.55, P < 0.001, RMR = 0.06, GFI = 0.73, NFI = 0.90, TLI = 0.91, CFI = 0.92, RMSEA = 0.10). Spearman's correlations and known-groups comparisons supported construct validity. The newly translated DFS-SF-K may be used to assess the impact of QoL with DFUs in Korean patients.

PURPOSE

To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability.

METHODS

A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's α (0.90 for total item, 0.80 to 0.88 for factors).

RESULTS

The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90.

CONCLUSION

These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

[Reliability and Validity of the Korean Version of the Perinatal Post-Traumatic Stress Disorder Questionnaire]

PURPOSE

The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was designed to measure post-traumatic symptoms related to childbirth and symptoms during postnatal period. The purpose of this study was to develop a translated Korean version of the PPQ and to evaluate reliability and validity of the Korean PPQ.

METHODS

Participants were 196 mothers at one to 18 months after giving childbirth and data were collected through e-mails. The PPQ was translated into Korean using translation guideline from World Health Organization. For this study Cronbach's alpha and split-half reliability were used to evaluate the reliability of the PPQ. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group validity were conducted to examine construct validity. Correlations of the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory (BAI) were used to test a criterion validity of the PPQ.

RESULTS

Cronbach's alpha and Spearman-Brown split-half correlation coefficient were 0.91 and 0.77, respectively. EFA identified a 3-factor solution including arousal, avoidance, and intrusion factors and CFA revealed the strongest support for the 3-factor model. The correlations of the PPQ with IES, BDI-II, and BAI were .99, .60, and .72, respectively, pointing to criterion validity of a high level.

CONCLUSION

The Korean version PPQ is a useful tool for screening and assessing mothers' experiencing emotional distress related to child birth and during the postnatal period. The PPQ also reflects Post Traumatic Stress Disorder's diagnostic standards well.
