RESUMEN

The dissolved organic matter (DOM) with high mobility and reactivity plays a crucial role in soil. In this study, the characteristics and phytotoxicity of DOM released from the hydrochars prepared from different feedstocks (cow manure, corn stalk and Myriophyllum aquaticum) under three hydrothermal carbonization (HTC) temperatures (180, 200 and 220°C) were evaluated. The results showed that the hydrochars had high dissolved organic carbon content (20.15 to 37.65 mg/g) and its content showed a gradual reduction as HTC temperature increased. Three fluorescent components including mixed substance of fulvic acid-like and humic acid-like substances (C1, 30.92%-58.32%), UVA humic acid-like substance (C2, 25.27%-29.94%) and protein-like substance (C3, 11.74%-41.92%) were identified in hydrochar DOM by excitation emission matrix spectra coupled with parallel factor analysis. High HTC temperature increased the relative proportion of aromatic substances (C1+C2) and humification degree of hydrochar DOM from cow manure, while it presented adverse effects on the hydrochar DOM from corn stalk and Myriophyllum. aquaticum. The principal component analysis suggested that feedstock type and HTC temperature posed significant effects on the characteristics of hydrochar DOM. Additionally, seed germination test of all hydrochar DOM demonstrated that the root length was reduced by 8.88%-26.43% in contrast with control, and the germination index values were 73.57%-91.12%. These findings provided new insights into the potential environmental effects for hydrochar application in soil.

RESUMEN

BACKGROUND: Sexual and reproductive empowerment (SRE) is an important determinant of women's and girls' health yet measuring it is complex due to cultural and domain-specific variations. This study describes the process of adapting an SRE scale consisting of four domains (self-efficacy; future orientation; social support; and safety) and testing its psychometric properties among Arabic speaking adolescent girls in Lebanon. METHODS: An SRE scale developed in a Western context was adapted in four steps: (1) reviewing the scale and selecting culturally appropriate domains for translation to standard Arabic; (2) conducting cognitive interviews with 30 11-17-year-old adolescent girls in Lebanon; (3) administering the scale to 339 refugee adolescent girls who participated in an early marriage intervention; and (4) conducting confirmatory factor analysis (CFA) on the data to assess the scale's psychometric properties. RESULTS: The original model for the 13-item, four-domain adapted scale demonstrated poor fit in CFA. After iteratively removing two items, scale properties were improved, albeit were not optimal. The validity and reliability results for the self-efficacy domain were acceptable. Cognitive interview data revealed that Arab adolescent girls understood self-efficacy in relational terms, recognizing that autonomous decision-making is not necessarily favored but is influenced by parents and family. CONCLUSIONS: This study presents an effort to customize an SRE scale for use in studies on the health of adolescent girls in an Arab cultural context. Findings from cognitive interviews highlight the importance of taking into consideration relationality in adolescent sexual and reproductive decision-making. The self-efficacy domain in the adapted scale demonstrates acceptable psychometric properties and is recommended for use in health studies to capture SRE.

RESUMEN

PURPOSE: The purpose of this study was to develop an Infertility Perception Scale for Women (IPS-W). METHODS: Initial items were based on an extensive literature review and in-depth interviews with five infertile women and fifteen women not diagnosed with infertility. Forty-one items were derived from a pilot survey. Data were collected from 203 women who had experienced intrauterine insemination (IUI) and in-vitro fertilization (IVF) more than once. The data were analyzed to verify the reliability and validity of the scale. RESULTS: Four factors containing 21 items were extracted from the exploratory factor analysis (EFA) to verify the construct validity. The four factors of infertility perception scale were perceived feelings, personal stigma, social stigma, and acceptance. These factors explained 59.3% of the total variance. The confirmatory factor analysis (CFA) confirmed a four-factor structure of the 21-item IPS-W. All fit indices were satisfactory (χ2/df ≤ 3, RMSEA < 0.08). These items were verified through convergent, discriminant, known group validity, concurrent validity testing. The internal consistency reliability was acceptable (Cronbach's α = 0.90). CONCLUSION: The scale reflects the perception of infertility within the cultural context of Korea. The findings can help nurses provide support that is appropriate for individual circumstances by examining how women experiencing infertility perceive infertility.

RESUMEN

BACKGROUND: Adverse Childhood Experiences (ACEs) and Parental Alienation (PA)are forms of adverse events negatively affecting children globally. The current study was to identify a revised ACEs measure that includes a screening item for PA. METHODS: A total of 231 undergraduate students, ages 18 to 37, were surveyed for this analysis. A factor analyses was performed to identify what PA item, out of four, would correlate most strongly with existing ACEs scale items. Convergent and divergent validity was assessed. An exploratory factory analyses was conducted to identify factor structure of scale items and a confirmatory factory analysis of extracted factors was used to assess model fit. RESULTS: Over half (60 %) of the sampled population reported at least one ACEs item. All four PA items were significantly correlated with converging constructs (r = 0.68, p < .01). Out of four PA items, one PA item significantly outperformed the other three items in relation to convergent validity and was used to create a new ACEs-PA scale item (r = 0.33, p < .01). A two factor solution was identified with the new PA item loading, accounting for 35 % of the variance, explaining more variance in both outcomes (R2 = 0.43 and R2 = 0.16) than the original ACEs scale when comparing the adjusted R2 values (R2 = 0.35 and R2 = 0.13). Limitations This study used participant self-reporting methods subjecting it to retrospective bias. CONCLUSION: Within the population, the new PA item factored significantly with existing ACEs, suggesting the capture of an additional adverse childhood experience.

RESUMEN

OBJECTIVE: To compile a scale of Chinese college students' perception of teachers' differential behavior and to provide a reference for college students to establish correct life values, promote college students' physical and mental health, and reduce teachers' differential treatment. METHODS: Open-ended questionnaires and expert interviews were used to conduct interviews and correspondence with 58 college students, ten psychologists, and six psychologists to form an initial questionnaire. Then, the scale's exploratory factor analysis, confirmatory factor analysis, and reliability and validity test were conducted on 7053 college students from 18 universities in 6 provinces (municipalities directly under the Central Government). RESULTS: The Chinese college students' perception of teachers' differential behavior scale has two dimensions: teacher prejudice and preference. Each dimension includes three aspects: emotional feedback, behavior orientation, and opportunity privilege, and each aspect have a total of 4 items. The consistency test coefficients of each dimension and each factor of the prepared scale are all above 0.7, and the split-half reliability is above 0.6. Confirmatory factor analysis shows that the six-factor structural model fits well (χ2/df = 4.287, RMSEA = 0.066, CFI = 0.950, TLI = 0.919). Using the generalized anxiety disorder scale and the patient health questionaire-9items as empirical criteria, each factor in the scale demonstrated significant correlations with both the GAD scale and the patient health questionaire-9items. CONCLUSIONS: The Chinese college students' perception of teachers' differential behavior scale has a two-dimensional six-factor structure and has good reliability and validity. It can be used as an effective tool to measure Chinese college students' perceived teacher differential behavior.

RESUMEN

The adjustment of stroke survivors is self-directed and multi-dimensional. This study developed an adaptive behavior scale for stroke survivors reflecting these characteristics and performed a psychometric evaluation. The item pool was derived based on conceptual attributes and indicators of adaptive behaviors for stroke survivors. Ten experts assessed the content validity. The scale was refined through pilot testing and interviews with 10 stroke survivors. From December 2021 to May 2022, a self-report questionnaire consisting of a five-point Likert scale was administered to 215 stroke survivors visiting a university hospital in S City, South Korea. Item analysis and confirmatory factor analysis were conducted to assess the construct validity; reliability was confirmed using Cronbach's α. The final scale comprised three factors and 16 items: taking an optimistic view, restructuring daily activities to suit oneself, and carrying out one's daily life. The confirmatory factor analysis indicated a good fit for the three-factor model; Cronbach's α coefficient of the scale was 0.90, indicating a very good internal consistency. This easy-to-use, concise self-report scale applies to stroke survivors from subacute to chronic stages, providing healthcare professionals with the basic data needed to assess their adaptation. It may also facilitate individualized intervention program development to improve stroke survivor adaptation.

RESUMEN

BACKGROUND: This study aimed to analyze the psychometric properties of the Brief-COPE Inventory and to determine its concurrent validity by examining its association with perceived stress among Peruvian nurses. METHODS: A psychometric study was conducted with 434 Peruvian nurses to evaluate the psychometric properties of the Brief-COPE Inventory through confirmatory factor analysis. Three stepwise variable selection regression models were implemented. RESULTS: The three-factor model of the Brief-COPE Inventory demonstrated adequate fit indices (root mean square error of approximation = 0.052, standardized root mean square residual = 0.068, and both the comparative fit index and the Tucker-Lewis index = 0.95). Additionally, the factors were significantly correlated (p < 0.001), and the reliability was adequate (ω = 0.90). Nurses reported a medium level of perceived stress, with associated factors including having received stress management training, fear of COVID-19, and problem-focused coping strategies (p < 0.05). CONCLUSION: This study confirms that the Brief-COPE Inventory is a valid tool for measuring coping strategies among Peruvian nurses due to its good model fit, excellent reliability, and concurrent validity with perceived stress. However, further research is needed to assess its validity in the specific areas of performance perceived by nursing professionals.

RESUMEN

Hip Disability and Osteoarthritis Outcome Survey (HOOS) was developed as a region- and disease-specific outcome to assess hip disability. Despite the use of the HOOS in clinical practice and research, psychometric analyses of the scale in a large dataset of patients have not been performed. As such, the purposes of this study were to assess the structural validity of the HOOS in patients who underwent a total hip arthroplasty. Data were obtained from the Surgical Outcome System (SOS) global registry. Confirmatory factor analysis (CFA) was conducted to assess the scale structure of the 40-item HOOS and exploratory factor analysis (EFA) was conducted to identify a parsimonious scale structure. The parsimonious model identified was subjected to multi-group and longitudinal invariance testing and LGC modeling. The original five-factor, 40-item HOOS did not meet recommended model fit indices values (CFI = 0.822, TLI = 0.809, IFI = 0.822, RMSEA = 0.085). Alternate model generation identified an alternative model (i.e., HOOS-9). Sound model fit was identified for the HOOS-9 (CFI = 0.974, TLI = 0.961, RMSEA = 0.046). Invariance testing criteria were also met between groups (i.e., age and sex) and across time. Lastly, a nonlinear growth trajectory was identified in responses pertaining to hip disability. The original scale structure of the 40-item HOOS was not supported. The HOOS-9 met contemporary model fit recommendations, along with multi-group and longitudinal invariance testing. Our findings support the preliminary use of the HOOS-9 to assess hip function and disability in research and clinical practice.

RESUMEN

The microbial terroir is an indispensable part of the terroir panorama, and can improve wine quality with special characteristics. In this study, eight autochthonous yeasts (Saccharomyces cerevisiae), selected in Huailai country, China, were trailed in small-scale and pilot fermentations for both white (Riesling and Sémillon) and red (Cabernet Sauvignon and Syrah) wines and evaluated by GC-MS analysis and the rate-all-that-apply (RATA) method. Compared to commercial yeast strains, the indigenous yeasts were able to produce higher concentrations of ethyl esters and fatty acid ethyl esters, and higher alcohol, resulting in higher odor activity values of fruity, floral attributes. Marked varietal effects were observed in the pilot fermentation, but yeast strains exerted a noticeable impact in modulating wine aroma and sensory profile. Overall, indigenous yeast could produce more preferred aroma compounds and sensory characteristics for both white and red wines, demonstrating the potential for improving wine quality and regional characteristics.

RESUMEN

BACKGROUND: Obesity is commonly aggregated with indices of metabolic health. Proponents of body positivity approaches question whether body size is a determinant of health and well-being. Our objective was to conduct an exploratory factor analysis (EFA) to determine if body size measurements factor load with or independent of metabolic health measures. METHODS: The EFA was conducted on n= 249 adults using baseline data from four weight loss trials (Sample 1: n = 40; Sample 2: n = 52; Sample 3: n = 53; Sample 4: n = 104). An EFA of nine items (systolic blood pressure [SBP], diastolic blood pressure [DBP], hemoglobin A1c [HbA1c], HDL-cholesterol [HDL], LDL-cholesterol [LDL], total cholesterol [TC], body mass index [BMI], body fat percent BF%], and waist circumference [WC]) was conducted with oblique rotation. RESULTS: Three factors were retained, which produced a model explaining 87.5% of the variance. Six items loaded strongly (>0.8) under three components and were selected for retention (Factor 1: LDL and TC; Factor 2: BMI and WC; Factor 3: SBP and DBP). CONCLUSION: Body size measures loaded separately from measures of metabolic health and metabolic health were further split into lipid- and blood pressure-focused factors. These results support weight-neutral interventions to improve overall health and well-being.

RESUMEN

OBJECTIVE: To evaluate the psychometric properties of the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ-70) among general hospital psychiatric outpatients. METHODS: A total of 2000 participants responded to the survey. Factor analyses were used to test the construct validity of the scale. Convergent validity was evaluated by the correlation between UPPSAQ-70 and symptoms measured using the Chinese versions of Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Patient Health Questionnaire-15 (PHQ-15), Somatic Symptom Disorder - B Criteria Scale (SSD-12) and Pittsburgh Sleep Quality Index (PSQI). RESULTS: The nine-factor model was supported (χ2 = 8816.395, df = 2309, χ2/df = 3.818, RMSEA = 0.053, CFI = 0.929). The UPPSAQ-70 showed significant correlation with the SAS (r = 0.396, P < .001), SDS (r = 0.451, P < .001), PHQ-15 (r = 0.381, P < .001), SSD-12 (r = 0.324, P < .001) and PSQI (r = 0.220, P < .001). UPPSAQ-70 and its subscales showed good internal consistency with Cronbach's alpha coefficients ranging from 0.79 to 0.96. CONCLUSIONS: The UPPSAQ-70 was a rating scale with good construct validity and reliability, which can measure overall health in the biological, psychological, and social domains for Chinese psychiatric outpatients, but its convergent validity still requires further empirical research.

RESUMEN

PURPOSE: Although school-based planned education has steadily been introduced, master-apprentice learning is still an indispensable part of medical education. All medical clinical teachers begin their careers as medical students, often without knowing exactly how they will learn to teach. Kilminster and Jolly identified three primary functions of clinical supervisors including clinical teaching, support and guidance, and work supervision. Therefore, we designed a study using questionnaires to assess the three factors of clinical educators for past supervised experiences, including 'being instructed,' 'being supported,' and 'being supervised,' based on Kilminster and Jolly's illustration in 2000, to see the relationship between the three factors mentioned above. MATERIALS AND METHODS: The study started with a literature review to construct the essential items regarding past supervised experiences of physicians as clinical teachers. We invited 10 experts from fields including medical education and experienced clinical teachers to assess the content validity. One hundred physicians in teaching hospitals were sampled for the preliminary test. Another 364 physicians in teaching hospitals were sampled for the formal study of confirmatory factor analysis and pathway analysis. RESULTS: The" Past Supervised Experiences with Educational Roles Scale" showed satisfying reliability with all Cronbach's α values exceeding .80, and three factors from supervised experiences were identified, including 'being supported,' 'being instructed,' and 'being supervised.' In our model, the 'being supported' experience could positively affect 'being supervised' with significance, directly and indirectly, by being instructed. CONCLUSIONS: Our study developed a validated instrument that allows investigation of the formation of better-supervised experiences from current physicians. Our findings inspired us to focus more on supportive coaching in teaching and supervising medical trainees. Our study indicated that faculty development for skills of supporting students is crucial to effective clinical teaching and supervision.

RESUMEN

Despite the importance of social support in ostomy care, the Multidimensional Scale of Perceived Social Support (MSPSS) does not appear to be validated in the context of ostomy care. This study evaluated the psychometric characteristics of MSPSS in ostomy patients and their informal caregivers. The MSPSS was tested in a sample of 775 participants with confirmatory factor analysis. Internal consistency reliability was assessed with the ordinal Omega coefficient. Criterion-related validity was ascertained via hypothesis testing by correlating the scores of the MSPSS with other measures. MSPSS for patients and caregivers has a three-factor structure with a good fit. Internal consistency reliability of the factors was excellent. Concurrent validity was supported by the negative correlations between MSPSS scores with depression and stoma-related QoL, and the positive correlations with perceived mutuality. Our research indicates that the MSPSS is a sound measure of social support for ostomy patients and their caregivers.

RESUMEN

BACKGROUND: Palliative care provides holistic support, addressing physical, psychological, social, emotional, and spiritual dimensions of suffering, known as "total pain", to improve patients' quality of life. Patients often rely on healthcare professionals, particularly nurses, for support. This study aimed to develop and validate questionnaires assessing nurses' perceptions of psychological, social, and spiritual issues in palliative care and their effectiveness in managing them. METHODS: Two self-rated questionnaires were created: the Psychological, Social, and Spiritual Problems of Palliative Patients' Questionnaire and the Effectiveness in Coping with the Psychological, Social, and Spiritual Challenges of Palliative Care Patients. The study surveyed 237 nurses caring for palliative patients in Split Dalmatian County, Croatia. RESULTS: The questionnaires demonstrated high reliability with Cronbach's α values of 0.98 and 0.99. Factor analysis revealed four factors for the first questionnaire and three for the second. Nurses primarily perceived patients as experiencing fear and emotional/spiritual suffering, with the greatest difficulty coping with the fear of the disease outcomes. Nurses acknowledged the need for improvement in addressing patient challenges, highlighting gaps in the Croatian system. CONCLUSIONS: Ongoing efforts are crucial to prioritize palliative care globally, with nursing professionals playing a vital role in symptom management.

RESUMEN

PURPOSE: This study aimed to develop a Hybrid Clinical Practicum Environment Scale for Nursing Students (HCPES-NS) and verify its validity and reliability. METHODS: The HCPES-NS was constructed following the DeVellis guidelines. The initial items were written based on a literature review and individual in-depth interviews. Content validity was verified through an expert panel review. To confirm the validity and reliability of the scale, a survey was conducted with 449 nursing students enrolled in 12 nursing colleges. Data were analyzed using item analysis, exploratory factor analysis, confirmatory factor analysis, concurrent validity, and reliability tests. RESULTS: Factor analysis showed that the HCPES-NS consists of 15 items on five subdomains: clinical site atmosphere, interpersonal relationship, alternative online practicum contents, provision of learning information, and clinical performance facilitation. A higher score indicated a more positive perception of the clinical practicum environment. The concurrent validity of the HCPES-NS was confirmed by its positive correlation with the Clinical Learning Environment Scale (r = .77). The Cronbach's α reliability of the HCPES-NS was .84. CONCLUSION: The HCPES-NS is both valid and reliable. This scale reflects the clinical practicum environment and includes an online practicum factor. It may be used effectively by faculty members and educators to evaluate nursing students' perceptions of clinical practicum environments.

RESUMEN

PURPOSE: Restricted and/or repetitive displays of behavior, interests, or activities (RRBs) are one of the core symptom domains of autism spectrum disorder (ASD). Current and past research indicates two 'clusters' of RRBs in children with ASD: repetitive sensorimotor (e.g., hand/finger and more complex motor mannerisms) and insistence on sameness (e.g., resistance to changes in the environment) behaviors. The current study aims to fill a gap by examining how RRBs may diverge in individuals with ASD and with other neurodevelopmental disorders (ONDD) in a clinical sample. METHODS: A total of 558 individuals were seen at a tertiary care clinic for a comprehensive clinical assessment of ASD. The sample was split into ASD (n = 292 individuals) and ONDD (n = 266) groups based on clinical diagnosis. Exploratory factor analyses were conducted using Autism Diagnostic Interview-Revised (ADI-R) RRB item scores for the overall sample, the ASD group, and the ONDD group. RESULTS: Exploratory factor analysis of ADI-R RRB items indicated a 2-factor solution for the full sample and ASD group. Items loaded onto two factors comprised of "Repetitive Sensorimotor" and "Insistence on Sameness" behaviors, consistent with previous literature. Results demonstrated a unique loading pattern for the non-ASD group, with items clustering into "Higher Order" (e.g., circumscribed interests) and "Lower Order" (e.g., hand and finger mannerisms) behaviors. CONCLUSION: The results of the current study may point towards using RRBs to guide screening of children who are referred for an ASD evaluation to better identify children who are at higher risk of having ASD.

RESUMEN

Current knowledge on the sexual fantasies of minor attracted persons (MAPs) is primarily focused on these individuals' attraction to minors. Furthermore, MAPs' sexual fantasies are often perceived as revolving systematically around scenarios involving a minor. However, this raises the question of whether their sexual fantasies extend beyond minors. To explore this, we analyzed data from 403 MAPs (364 men and 39 women), using a modified Joyal Sexual Fantasy Questionnaire (JSFQ). Our exploratory factor analysis (EFA) revealed 5 factors: Male Partner Focused Fantasies (α = 0.905), Female Partner Focused Fantasies (α = 0.882), Coercing Focused Fantasies (α = 0.867), Promiscuous/Unattached Focused Fantasies (α = 0.848), and Romantic/Relational Sexual Fantasies (α = 0.650). These results not only highlight the diversity of MAPs' sexual interests of beyond their attraction to minors, paving the way for further research, but also suggest new perspectives for practitioners.

RESUMEN

Gerontological interventions should address the various geriatric syndromes suffered by the elderly, such as neurodegenerative diseases. Therapeutic lying is an effective and humanizing strategy to deal with dementia, used by various disciplines in the social and healthcare fields. This intervention strategy is made up of all the different responses to reality that are given to a person with cognitive impairment. This study analyzes the validity of the Spanish adaptation of the Attitudes toward Lying to People with Dementia (ALPD) questionnaire, given to 253 social workers who directly and indirectly intervened with older people suffering from cognitive impairment in public and private centers in Spain during the year 2022. The results of the validity and reliability analyses support the psychometric quality of ALPD for use in Spanish social workers. The statistical results indicate a good fit of the bifactor model (person-focused and lie-focused) and show the questionnaire to be reliable, with adequate psychometric properties. The article concludes with a discussion of practical, formative, and ethical challenges for social work in the field of geriatric services.

RESUMEN

Researchers and clinicians are becoming increasingly aware of the importance of assessing positive functioning to inform clinical outcomes. This paper evaluates the Questionnaire on Well-Being (QWB, available for free https://doi.org/10.17605/OSF.IO/GSC3R), a clinically informed instrument that assesses subjective well-being, across two studies. Study One, consisting of treatment-seeking individuals in an assertiveness training sample (n = 495), explored the factorial structure of the QWB, assessed the four-week test-retest reliability, criterion-related validity, and identified a preliminary cutoff point for the QWB with clinical significance. Study Two, including participants from the general public (n = 1561), confirmed the factorial structure of the QWB and further evaluated criterion-related validity. The results provided support for a unidimensional structure for the QWB. Furthermore, the QWB exhibited excellent internal reliability (Cronbach's alpha = 0.93 and 0.94 in Study One and Two, respectively), high test-retest reliability (ICC3 = .50 at a four-week follow-up in Study One), and appropriate criterion-related validity demonstrating positive correlations with positive affect and negative correlations with psychopathology. Finally, a cutoff point on the QWB below 50 was associated with marked psychopathology. These findings provide preliminary support for the usage of the QWB in clinical and non-clinical settings, establishing the QWB as a reliable indicator of subjective well-being.

RESUMEN

BACKGROUND: Early mobilisation is beneficial to support recovery among critically ill patients. The literature highlights the benefits of family engagement in early mobilisation, yet this practice remains underutilised. Effective implementation depends on understanding the key antecedents that influence family engagement in early mobilisation, specifically families' knowledge, contemplation, confidence and readiness. However, no measurement tools currently exist to assess these. Therefore, developing a psychometrically supported instrument is essential to understanding and enhancing families' factors influencing their engagement in early mobilisation. AIM: To develop and evaluate the psychometric properties of an instrument to assess families' knowledge, contemplation, confidence and readiness to engage in early mobilisation. DESIGN: A multi-site cross-sectional survey design. METHODS: Based on established psychological theory (Social Cognitive Theories and Behaviour Change Theories), an item pool was developed to assess families' knowledge, contemplation, confidence and readiness to participate in early mobilisation. To psychometrically evaluate the new tool, a multi-site cross-sectional survey was undertaken from May 2020 to June 2022 across five intensive care units in Australia. Data from 370 families of critically ill patients were used to evaluate the structural, convergent and discriminant validity as well as the reliability of the new instrument. RESULTS: Confirmatory factor analysis indicated good model fit, supporting the proposed structure. All items displayed high standardised factor loadings except one, which improved upon freeing an error covariance. Positive inter-factor correlations were moderate to strong and were substantially lower than the square root of the average variance extracted, supporting both convergent and discriminant validity, respectively. Additionally, all subscales demonstrated well to excellent reliability. CONCLUSION: The findings provide preliminary support for the multiple types of validity evidence and the reliability of the instrument. This new instrument is suitable for use in clinical and research applications to assess families' knowledge, contemplation, confidence and readiness for their engagement in early mobilisation. IMPACT: Family engagement in early mobilisation activities may have multiple benefits but it is not commonly implemented in the ICU. Factors influencing family engagement in early mobilisation are poorly understood. Influential psychological theories highlight the likely importance of knowledge, contemplation, confidence and readiness. A readily available instrument designed to assess these constructs among family members is needed to deepen research understanding and guide clinical practice. The proposed instrument is designed to measure factors influencing family engagement in early mobilisation, which may support healthcare professionals and health services to identify and tailor strategies to support family engagement in early mobilisation. REPORTING METHOD: Recommendations for reporting the results of studies of instrument and scale development and testing was followed to report this study. PATIENT OR PUBLIC CONTRIBUTION: Family members of adult critically ill patients participated in this study, and they provided the data through the survey.
