  • For test-retest reliability, it is important to consider whether the attributes of the construct being measured is temporally stable or not. For responsiveness, it needs a longitudinal study design including a treatment/intervention known to induce a change on the construct to be measured.

Psychometric properties of an instrument 2: structural validity, internal consistency, and cross-cultural validity/measurement invariance (측정도구의 심리계량적 속성 2: 구조타당도, 내적일관성 및 교차문화타당도/측정동일성)

  • Structural validity, internal consistency, and cross-cultural validity/measurement invariance are psychometric properties of the internal structure of an instrument. In psychometric studies published in Korean nursing journals, structural validity has mainly been assessed using confirmatory factor analysis. Cross-cultural validity/measurement invariance has rarely been evaluated. It is recommended for Korean nursing researchers to evaluate the internal structure of instruments using a greater variety of methods, such as item response theory, Rasch analysis, multi-group confirmatory factor analysis, and differential item functioning.

  • Source memory is a cognitive process that combines the representation of the origin of the episodic experience with an item. By studying this daily process, researchers have made fundamental discoveries that make up the foundation of brain and behavior research, such as executive function and binding. In this paper, we review and conduct a bibliometric analysis on source memory papers published from 1989 to 2020. This review is based on keyword co-occurrence networks and author citation networks, providing an in-depth overview of the development of source memory research and future directions. This bibliometric analysis discovers a change in the research trends: while research prior to 2010 focused on individuality of source memory as a cognitive function, more recent papers focus more on the implication of source memory as it pertains to connectivity between disparate brain regions and to social neuroscience. Keyword network analysis shows that aging and executive function are continued topics of interest, although frameworks in which they are viewed have shifted to include developmental psychology and meta memory. The use of theories and models provided by source memory research seem essential for the future development of cognitive enhancement tools within and outside of the field of Psychology.

  • 내용타당도는 측정도구의 내용이 측정하고자 하는 구성개념을 얼마나 적절히 반영하고 있는가에 대한 것이다. 그 과정은 예비측정 도구 개발 단계와 개발된 것이 측정하고자 하는 구성개념을 잘 반영하는지를 판단하는 단계로 나누어 볼 수 있다. 첫 번째 단계에서는 측정하고자 하는 구성개념에 대한 개념화와 예비질문지 개발이 이루어진다. 그 후, 전문가와 측정도구를 사용하고자 하는 대상자를 대상으로 개발된 예비문항의 관련성, 포괄성, 및 이해성을 판단하게 된다.

Internal Structure of the Health-Related Quality of Life Instrument with 8-Items in a Nationally Representative Population (한국형 건강 관련 삶의 질 측정도구(Health-Related Quality of Life Instrument with 8-Items)의 심리계량적 내적구조 평가: 국민건강영양조사 8기 1차년도 자료 적용)

  • Purpose: This study evaluated the internal structure (structural validity, internal consistency, and measurement invariance) of the Health-Related Quality of Life Instrument with Eight Items (HINT-8), developed to measure Korean people's health-related quality of life. Methods: A secondary analysis was conducted using data from the Korea National Health and Nutrition Examination Survey, involving 6,167 adults aged over 18 years. The structural validity of the HINT-8 was assessed using exploratory graph analysis and confirmatory factor analysis. Internal consistency and measurement invariance were analyzed using McDonald's omega (ω) and multigroup confirmatory factor analysis, respectively. Results: The HINT-8 had a single dimension and good internal consistency (ω =.804). The one-dimension HINT-8 exhibited matric invariance but not scalar invariance across sociodemographic groups (sex, age, education, and marital status). Further, it exhibited scalar or partial scalar invariance across medical condition groups (hypertension, diabetes, depressive symptoms, and cancer). Conclusion: The study finds that the HINT-8 demonstrated satisfactory structural validity and internal consistency, indicating its suitability for practice and research. However, the HINT-8 scores cannot be compared across different groups regarding sex, age, education, and marital status, as the interpretation varies within each sociodemographic category. Conversely, interpretation of the HINT-8 is consistent for individuals with and without hypertension, diabetes, depressive symptom, and cancer.

  • Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in a room. Architectural design has a need for daylight prediction. But it is difficult to predict the illuminance values in daylight system. Using various Daylight simulation software is easy and simple, but we can find different results under the same conditions. This study compares with illuminance values from simulation (Lightscape 3.2, Relux 2007, Radiance 3.9) and Mock-up experiment with a same space and parameter of daylight (location of space and window, date, time and sky condition).

  • 인간은 누구를 막론하고 미지의 지역에 대한 동경과 아울러 그 지역을 방문해 보고자 하는 기본적인 심리를 가지고 있다. 특히 경제적 여유가 신장되고 관광에 대한 일반의 관심이 대단히 높아지면서 우리 주변에 산재하고 있는 관장자원들에 대해 관심을 가지게 된다. 지속적으로 늘어나는 관광객들 개개인의 서로 다른 욕구와 취향, 또는 외부적 여건으로 인한 지각(Perception)의 결과 관광 환경에 대한 상이한 Image가 형성될 것이며, 이는 곧 관광 주체로 하여금 관광지를 선택하게 하는데 있어서 중요한 역할을 하게 될 것이다. 관광지리학 분야에서의 관광자원 또는 Wildness에 대한 인지행동론적 연구는 1960년대의 주관적 환경을 강조하는 행태지리학에서 시작되었으며 관광 목적지에 대한 지각, 인지, Mental Map, 관광행태 등을 포함하고 있다. 이러한 연구들은 대부분 계량적이고 실증적인 시대의 전형적인 산물로서 관광객들의 직접적인 관광형태로 나타나게 하는 의사결정 과정을 중시하는 것이다. 일반적으로 환경에 대한 인지는 과거에 개인의 경험과 현재의 다양한 주변 여건에 의해 크게 달라질 수 있다. 오늘날 인지행태론적 연구는 관광지리학 뿐만 아니라 심리학, 사회학, 인류학 등 사회과학 전반에 걸쳐 연구가 활발하게 이루어 지고 있다. 따라서 본 논고에서는 관광지 및 관광자원에 대한 국내외의 인지행태론적 연구를 검토해 보고 이러한 연구에 많이 이용되고 있는 MDS 분석법을 살펴 보고자 한다.

  • Before evaluating convergent, discriminant, and known-groups validity, it is suggested to design an instrument that reflects hypothetical relationships or differences with other comparator instruments or groups. For criterion validity, a gold-standard instrument measuring the same construct should be carefully selected.

  • The purpose of this study is to suggest the objective basic data for applying to development and conservation management of the national park through the quantitative analysis of the visual quality included in the and physical environment of the Tokyusan National Park. For this, spatial images and structures, of natural elements have been analyzed by factor analysis algorithm, and degree of visual quality has been measured mainly through questionnaries. Result of this study can be summarized as follows. Factors covering the spatial image of the Tokyusan National Park landscape have been found to be the overall synthetic evaluation, appeal, spatial, natural quality and dignity factors such as the overall synthetic evaluation, spatial and appeal yield high factor scores. The main factors determining the degree of visual quality are the clearness valley, peculiarity of configuration, natural of trail, harmony of suitable artificial planting and temple.

  • The purpose of this research is to provide synthesized findings on the effect of volunteering among the elderly on their life satisfaction and depression. In order to do that, we conducted a systematic review and meta-analysis from selected studies which were published in Korea. From five databases and three government web sites, 47 research papers were selected based on the eligible criteria and the 53 effect size data were extracted. The results are: The effect size of elderly volunteering on life satisfaction was 0.348 with 95% confidence interval of 0.286 to 0.408. The summary effect of elderly volunteering on depression was -0.310 with 95% confidence interval of -0.439 to -0.169. These findings suggest that elderly volunteering is an effective intervention for their psychosocial health, providing some evidence in the area of volunteering policies and practices.
