Internal structure of the Patient Health Questionnaire-9: A systematic review and meta-analysis.

Purpose: This review aimed to evaluate the internal structure (structural validity, internal consistency, and measurement invariance) of the Patient Health Questionnire-9 (PHQ-9), which is one of the most widely used self-administered instruments for assessing and screening depression.

PubMed, Embase, CINAHL, PsycINFO, and Cochrane Library databases were searched from their inception up to February 28, 2023.

Relationship Between Electronic Health Literacy and Self-Management in People With Type 2 Diabetes Using a Structural Equation Modeling Approach.

Background: Electronic health (eHealth) literacy is a relatively new concept used to determine health outcomes. However, it is not well known how eHealth literacy relates to health outcomes such as diabetes self-management.

Purpose: This study was designed to examine the relationships among eHealth literacy, self-efficacy, social support, and self-management in people with Type 2 diabetes.

Measurement invariance of the patient health questionnaire-9 depression scale in a nationally representative population-based sample.

The Patient Health Questionnaire-9 (PHQ-9) is widely used to measure the severity of depressive symptoms and to screen for depressive disorder, but its measurement invariance has received little research attention. The aim of this study was to assess the measurement invariance of the PHQ-9 across various sociodemographic and medical-condition groups. The structural validity and internal consistency of the PHQ-9 were also assessed as the prerequisite properties for measurement invariance.

Methods: Data were analysed using the PROCESS macro of SPSS.

Development and psychometric evaluation of a new brief scale to measure eHealth literacy in people with type 2 diabetes.

Background: The internet has become a major source of health information, and obtaining appropriate information requires various abilities and skills, labeled as electronic health literacy (eHealth literacy). The existing instruments for measuring eHealth literacy are outdated because they were developed during the Web 1.0 era, or not sufficiently sensitive for people with a specific condition or disease because they were designed to assess eHealth literacy over a broad range for a general population.

[Psychometric property of an instrument 4: reliability and responsiveness].

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.

Factors Associated with Cyto-Histological Misinterpretation of Cervical Smear according to Menopausal Status.

Objectives: This study aimed to compare histological outcomes between pre-menopausal and post-menopausal women with cervical cytological abnormalities and to investigate the clinical factors affecting the misinterpretation of cytology and histology.

Methods: We conducted a retrospective analysis of 599 patients with abnormal cervical cytology who underwent loop electrosurgical excision procedure (LEEP) between January 2010 and May 2019. Baseline characteristics were collected, including age, height, weight, body mass index, gravity, parity, and menopausal status.

Development and effects of a post-traumatic growth program for patients with breast cancer.

Purpose: This study aimed to develop a post-traumatic growth (PTG) program, based on the PTG promotion resources suggested by Cahlhoun, Cann, and Tedeschi, and to apply it to breast cancer patients to determine its effect.

Methods: A non-equivalent control group pretest-posttest experimental design was used. In total, 74 participants were enrolled in this study, with 37 in the experimental group and 37 in the control group.

Pathways Linking Health Literacy to Self-Management in People with Type 2 Diabetes.

Health literacy is considered to be an emerging determinant of health behaviors and outcomes. The underlying mechanisms linking health literacy to diabetes self-management are currently unclear. This study assessed a mediation model consisting of a direct pathway between health literacy and self-management, and indirect pathways via social isolation only, self-efficacy only, and social isolation and self-efficacy serially in people with type 2 diabetes.

eHealth Literacy Instruments: Systematic Review of Measurement Properties.

Background: The internet is now a major source of health information. With the growth of internet users, eHealth literacy has emerged as a new concept for digital health care. Therefore, health professionals need to consider the eHealth literacy of consumers when providing care utilizing digital health technologies.

[Psychometric properties of an instrument 3: convergent, discriminant, known-groups, and criterion validity].

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.

Psychometric properties of the revised Diabetes Knowledge Test using Rasch analysis.

Objective: The revised Diabetes Knowledge Test (DKT2) is the instrument that is the most widely used for measuring diabetes knowledge; nevertheless, its structural validity has never been evaluated. This study aimed to determine the psychometric properties of the DKT2.

Methods: This study performed a secondary data analysis of people with diabetes recruited at university hospitals.

[Psychometric properties of an instrument 2: structural validity, internal consistency, and cross-cultural validity/measurement invariance].

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.
