Background/Objectives: Despite the increasing recognition of person-centered care (PCC), existing evaluation tools often have profession-specific limitations, lacking broad applicability across interdisciplinary contexts. This study aimed to develop and validate the Person-Centered Care Instrument (PCCI), designed to assess the competence of healthcare providers from diverse professions. Methods: Using a two-round modified Delphi technique, ten experts validated an initial pool of 63 items. The process assessed both face validity (overall appropriateness) and content validity using a 9-point Likert scale and the Item-level Content Validity Index (I-CVI). Items with a median rating of 6 or higher and an I-CVI of ≥0.70 were retained. Results: The final PCCI consists of 37 items, with a scale-level content validity index of 0.65. Three items achieved universal agreement among the experts (I-CVI = 1.0). For the final 37-item PCCI, the Scale-level Content Validity Index (S-CVI) was 0.65, and the index based on universal agreement was 0.22. Conclusions: The developed PCCI demonstrated good face and content validity, making it a valid and broadly applicable tool for assessing competence in delivering PCC. This instrument can support quality improvement initiatives and help promote a culture of empathy and respect in healthcare.

Background/Objectives: This study aimed to develop the Technological Competency as Caring in Healthcare Providers Instrument (TCCHI) for multidisciplinary use, based on Locsin’s theory of Technological Competency as Caring in Nursing. Methods: A content validation design employing a modified Delphi technique was conducted with a multidisciplinary panel of 10 healthcare experts (recruited by purposive sampling based on expertise in technology/caring). The preliminary 67-item pool was derived from a literature review and theoretical alignment. Two Delphi rounds were implemented to establish face and content validity. Qualitative feedback from Round 1 guided item refinement for Round 2. The Wilcoxon matched-pairs signed-rank test was used to confirm the response stability between rounds. Results: Among the 67 initial items, 38 were retained after two Delphi rounds, achieving an I-CVI of 0.80–0.90. Response stability was established (p > 0.05). The resulting 38 items were categorized into six refined concepts reflecting the integration of technology and caring. Inter-rater consistency, assessed by the Intraclass Correlation Coefficient (ICC), was moderate (Round 1 ICC = 0.49; Round 2 ICC = 0.50), suggesting initial variability among the multidisciplinary panel. Conclusions: The TCCHI is a comprehensive and theoretically grounded instrument applicable across diverse healthcare disciplines. However, the moderate inter-rater consistency suggests that further empirical validation is required. Further psychometric evaluation, including confirmatory factor analysis and internal consistency reliability testing, is required to establish construct validity and strengthen the instrument’s applicability in diverse healthcare settings.

Background/Objectives: In patients with schizophrenia, gait disturbances (e.g., reduced walking speed and stride length) are linked to neural dysfunction and extrapyramidal symptoms. To inform gait rehabilitation strategies, this study examines the relationships of walking speed with extrapyramidal symptoms, stride length, antipsychotic dosage, ankle joint range of motion, and body composition in patients with chronic schizophrenia. Methods: Sixty-eight patients with chronic schizophrenia were included. All variables were described based on their measurement levels using non-parametric methods. Spearman’s rho was calculated to assess correlations. For multiple linear regression analyses, backward stepwise elimination was used to determine variables associated with walking speed. Statistical significance was set to p < 0.05. Results: Walking speed was positively correlated with stride length, chlorpromazine-equivalent dose, ankle plantar flexion, body mass index, bone mineral content, trunk muscle mass, and skeletal muscle mass index. In contrast, it was negatively correlated with drug-induced extrapyramidal symptoms scale (DIEPSS) scores for gait, bradykinesia, tremor, overall severity, and age. The multiple linear regression indicated that DIEPSS 2 bradykinesia level and ankle plantar flexion angle, adjusted for a 26% variance, best explained the walking speed. Conclusions: A lower bradykinesia severity and a higher ankle plantar flexion are associated with higher walking speeds. Thus, it is critical to assess stride length, bradykinesia, angle/limitation/torque of ankle plantar flexion, trunk and upper and lower limb muscle masses, and walking speed in patients with chronic schizophrenia. Specific strategies for gait rehabilitation should focus on stride training, plantar flexion strengthening exercises, and balance training.

Background/Objectives: With the increasing need for interprofessional team-based care, a practical framework is necessary to evaluate the caring competencies of healthcare providers. This study aimed to develop a refined, concise version of the Technological Competency as Caring in Healthcare Instrument (TCCHI) by: (1) reducing the items from the original 38-item Delphi-validated pool through confirmatory factor analysis (CFA) and (2) providing a preliminary assessment of its structural validity and reliability. Methods: An online survey was conducted with 528 healthcare professionals across Japan. The CFA process began with the 38 items identified in a previous Delphi study. To optimize model fit and ensure interprofessional applicability, items were systematically refined based on both statistical criteria and theoretical relevance, resulting in a 12-item, three-factor structure. Results: The final 12-item model demonstrated an improved and generally acceptable fit: chi-square to degrees of freedom ratio (χ2/df) = 3.96, comparative fit index (CFI) = 0.947, Tucker–Lewis Index (TLI) = 0.931, and Root Mean Square Error of Approximation (RMSEA) = 0.0749. All factor loadings were statistically significant (p < 0.001) and ranged from 0.437 to 0.83. Composite reliability (CR) for the three factors ranged from 0.700 to 0.827, meeting the threshold for internal consistency. While average variance extracted (AVE) values for some factors were below 0.50, the overall model provided a stable and theoretically consistent structure, albeit as a preliminary psychometric refinement. Conclusions: This study provides preliminary evidence for the structural validity and reliability of a refined 12-item, three-factor TCCHI. By offering a concise measurement tool aligned with caring theory, the TCCHI has the potential to support interprofessional assessment, education, and professional development in technology-mediated healthcare environments. However, further research is required to address issues of discriminant validity and confirm measurement invariance across different professional groups.

Background/Objectives: As healthcare increasingly depends on technology, instruments to evaluate the caring competencies of healthcare professionals beyond the nursing domain have become essential. This study aimed to develop the Technological Competency as Caring in Healthcare Providers Instrument (TCCHI) for multidisciplinary use, based on Locsin's theory of Technological Competency as Caring in Nursing. Methods: The face and content validation process used a two-round modified Delphi method. Ten experts were consulted to assess the proposed 67 items. Face validity addressed the overall appropriateness and relevance of the items, while content validity involved rating their relevance using the Content Validity Index with a 9-point Likert scale over two rounds. Items with a median rating of 6–9 and an item-level Content Validity Index (I-CVI) of ≥ 0.80 were retained. Results: Among the 67 initial items, 38 were retained after two rounds of the Delphi method, with an I-CVI of 0.80–0.90, indicating strong content validity. Conclusions: The TCCHI is a comprehensive and theoretically grounded instrument applicable across healthcare disciplines. TCCHI can measure the following concepts: (1) supporting healthcare professionals’ growth, (2) building trusting relationships with patients, (3) providing person-centered care, (4) enhancing the physical and emotional comfort of patients, (5) promoting patient learning and growth, and (6) engaging in ethico-moral practice. Using this instrument, healthcare professionals can evaluate their caring competencies in technologically advanced settings. The TCCHI can also be used to create in-service training plans and evaluate their effectiveness.

The rising prevalence of physical comorbidities among patients with mental illness has increased the relevance of physical rehabilitation within psychiatric care. However, specific physical rehabilitation practices in specialized psychiatric hospitals in Japan remain insufficiently documented. This exploratory and descriptive study aimed to characterize the rehabilitation content provided and to categorize patient characteristics and comorbidities in a single specialized psychiatric hospital using an expert-led consensus approach. Clinical data from 150 patients (median age 71.0 years) who received physical rehabilitation were retrospectively analyzed. Patient categorization was conducted through a multidisciplinary consensus-building process involving an expert panel of physical therapists, occupational therapists, psychiatrists, and nurses, each with over 10 years of clinical experience. Using a hierarchical rule set based on International Classification of Diseases, 10th Revision (ICD-10) codes and clinical referral data, five distinct categories were identified: Disuse Syndrome (41%), Neurologic Disorders (20%), Lower Limb Lesions (18%), Parkinson’s Syndrome (15%), and Upper Limb Lesions (6%). Across all categories, rehabilitation interventions focused on foundational motor therapies, such as range of motion (27%) and strength training (23%). Mobility-oriented interventions were selectively provided to patients with high bedridden status based on clinical potential. Overall, practices in this setting primarily targeted disuse syndrome and maintenance of basic motor function and were delivered with input from multiple professional disciplines; such practices may inform future research on structured multidisciplinary rehabilitative approaches, especially for aging psychiatric populations.
