El análisis factorial evidenció la existencia de una matriz de dos factores que explicó el 43.12% de la varianza total observada. Se obtuvieron evidencias favorables sobre validez y consistencia interna del instrumento (a= .86). Conclusiones. La versión ecuatoriana del BDI-II posee estructura bifactorial consistente con la versión original y adaptaciones precedentes realizadas al instrumento en otros países de habla hispana. Es apto para ser utilizado en el diagnóstico de síntomas depresivos en población adolescente en el contexto ecuatoriano.     The Beck Depression Inventory (BDI-II) is one of the most widely used clinical and research instruments to assess depression. Objective. To adapt and validate the BDI-II for its use in the identification of depressive symptoms in the adolescent population of Ecuador. Method. Instrumental study oriented to obtain the cultural adaptation, validity and reliability evidences of the BDI-II. A total of 871 adolescents between 13 and 18 years of age selected by non-probabilistic sampling participated. The content validity of the instrument was evaluated by means of judges' criteria and calculation of Kendall's W concordance coefficient. Factorial analysis was performed using the Principal Component Method. The association between variables was analyzed with Spearman's Rho correlation coefficient. The Beck Hopelessness Scale (BHS) and the Mood Rating Scale (EVEA) were used to evaluate the convergent validity of the BDI-II. Results. Factor analysis showed the existence of a two-factor matrix that explained 43.12% of the total variance observed. Favorable evidence was obtained on the validity and internal consistency of the instrument (a= .86). Conclusions. The Ecuadorian version of the BDI-II has a bifactorial structure consistent with the original version and previous adaptations made to the instrument in other Spanish-speaking countries. It is suitable for use in the diagnosis of depressive symptoms in the Ecuadorian adolescent population.

The aim of this study was to examine the psychometric properties of an adapted version of the Quantitative Checklist for Autism in Toddlers (Q-CHAT), an early screening tool that quantifies autistic traits dimensionally, in a community sample of Chilean children aged 18-24 months. An intentional non-probabilistic sampling was used. All primary caregivers of children aged 18-24 months who attended health check-up at four primary care clinics in Chile's Araucanía region during the study period were invited to participate. One hundred and eighty-eight toddlers were screened. Evidence of construct validity was determined through Exploratory Factor Analysis (EFA), evidence of convergent validity with the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F), and evidence of reliability through internal consistency and test-retest. The EFA showed a two-factor structure, which explained 42.2 % of the variance: “Restrictive and Repetitive Patterns” (factor 1), and “Communication and Social Interaction” (factor 2). The total Q-CHAT scores correlated positively and significantly with the total M-CHAT-R/F scores (r=0.59, p<0.01) with a large effect size. Internal consistency was acceptable for the scale in general (α=0.74), acceptable for factor 1 (α = 0.76) and good (α=0.85) for factor 2. Regarding test-retest stability, the intraclass correlation coefficient was good (ICC=0.86, p<0.001). In terms of the factor structure evidenced by the EFA, the two factors are theoretically consistent with the current diagnostic criteria of the DSM-5. The evidence of validity and reliability of Q-CHAT is encouraging when considering its use as an early detection tool in Chile.

Background: In health-care settings, the use of the Neuropsychiatric Inventory-Nursing Home (NPI-NH) may not always be consistent with the authors’ guidelines, which affects its reliability. To avoid this bias, a diary version of the NPI (NPI-Diary) was developed. Aims: This study aimed to evaluate the psychometric properties (internal consistency and reliability) of the NPI-Diary, and examined its convergence with the NPI-NH. Methods: Two raters administered the NPI-NH and NPI-Diary to 40 participants with Alzheimer’s disease, selected randomly from a hospital’s weekly turnover. Results: The NPI-Diary exhibited adequate internal consistency (total: α = 0.581) and test-retest reliability (total: ρ = 0.711; p < 0.01). The interrater reliability values (ICC) for the NPI-NH and NPI-Diary differed significantly (Total: NPI-NH ICC = 0.506, NPI-Diary ICC = 0.879; Frequency: NPI-NH ICC = 0.51, NPI-Diary ICC = 0.798; Severity: NPI-NH ICC = 0.491, NPI-Diary ICC = 0.809). The convergent validity between the two inventories was also significant (total: ρ = 0.48; p < 0.01). Conclusions: The NPI-Diary showed more appropriate validity and reliability compared to the NPI-NH, when administered in a highly variable sample, as is generally the case in the current health-care setting.

Introduction: Tobacco is the only legal product that kills a large proportion of its consumers when used as intended by its manufacturer. The effect of nicotine as a driving substance on smoking has been established for decades. Still, very little is known on how the biopsychosocial determinants relationship affects levels of nicotine addiction in smokers, especially in the urban low-income population. The study aimed to validate measurement scales related to biopsychosocial factors that will be used in the future study to evaluate biopsychosocial components that influence nicotine addiction among urban poor smokers. Methods: Exploratory factor analysis (EFA) using the principal component analysis with varimax rotation and Kaiser normalization was used to assess the factor structure. Then, the confirmatory factor analysis (CFA) was conducted to assess the unidimensionality, validity, and reliability of the latent construct. Results: EFA showed extraction of factors according to their original scales with all factor loading and communality's values were above 0.5. During CFA, factor loading less than 0.6 was deleted. Convergent validity verified by computing the Average Variance Extracted (AVE) for every construct range between 0.528 – 0.801. The Fitness Indexes achieved the required level (RMSEA=0.05, CFI=0.937, Chisq/df=1.7). Meanwhile, the Discriminant Validity Index range between 0.75-0.89, which is higher than the correlation coefficient value. Internal consistency assessed from Composite Reliability range between 0.714-0.965. Conclusion: The measurement scales are valid and reliable to assess the intended constructs among low-income male smokers in the urban area.

The Center for Epidemiological Studies-Depression (CES-D) scale is a widely used measure of depressive symptoms, but its psychometric properties have not been adequately evaluated among adults with HIV/AIDS. This study used an item response theory approach (Rasch analysis) to evaluate the CES-D’s validity and reliability in relation to key demographic and clinical variables in adults with HIV/AIDS. A convenience sample of 347 adults with HIV/AIDS (231 males, 93 females, and 23 transgenders; age range 22–77 years) completed the CES-D. A Rasch model application was used to analyze the CES-D’s rating scale functioning, internal scale validity, person-response validity, person-separation validity, internal consistency, differential item functioning (DIF), and differential test functioning. CES-D scores were generally high and associated with several demographic and clinical variables. The CES-D distinguished 3 distinct levels of depression and had acceptable internal consistency but lacked unidimensionality, five items demonstrated poor fit to the model, 15% of the respondents demonstrated poor fit, and eight items demonstrated DIF related to gender, race, or AIDS diagnosis. Removal of misfitting items resulted in minimal improvement in the CES-D’s substantive and structural validity. CES-D scores should be interpreted with caution in adults with HIV/AIDS, particularly when comparing scores across gender and racial groups.

Objective: This study aimed to compare the adaptability of the adapted version of Stress and Anxiety to Viral Epidemics-9 (SAVE-9) for public workers and the SAVE-6 scale and to validate them among public workers who are on the frontline of the coronavirus disease 2019 pandemic.Methods: A total of 300 public workers responded to the anonymous online survey during April 1–12, 2021. Principal component analysis was conducted with varimax rotation to explore the factor structure of this scale. Confirmatory factor analysis was also used to explore construct validity. Spearman correlation analysis of the scale with the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9) was performed to explore the convergent validity. The cut-off score in accordance with the mild degree of generalized anxiety symptoms (GAD-7 score of 5) was defined using the receiver operating characteristic (ROC) analysis.Findings: The single-structure model of each scale (the adapted version of SAVE-9 and SAVE-6) was adopted based on the results of the parallel analysis. Because SAVE-6 showed good construct validity, but the adapted version of SAVE-9 did not, we adopted to apply the SAVE-6 scale to assess the anxiety response of public workers in response to the viral epidemic. SAVE-6 showed good internal consistency (Cronbach's alpha = 0.817; McDonald's Omega = 0.818) and good convergent validity with GAD-7 (rho = 0.417, p &lt; 0.001) and PHQ-9 (rho = 0.317, p &lt; 0.001) scale scores. The appropriate cut-off score for SAVE-6 was determined to be ≥ 16.Conclusion: The SAVE-6 scale, as compared to the public workers' version of SAVE-9, is a reliable and valid rating scale to assess the work-related stress and anxiety of public workers due to the viral epidemic.

The purpose of present study is to develop and verify the questionnaire aimed at assessing the degree of unembodiment in the Internet as a consequence of using modern information technologies. The use of modern information technologies is associated with disembodiment, liberation of the Self from the body and related experiences. Immersion in virtual reality and “disembodiment” can cause the existential position of “unembodiement”, the features of which, according to the concept of the English psychologist R. Lang, are most clearly manifested in the clinic of schizoids. The study was conducted in the form of a psychodiagnostic survey, during which the reliability and validity of the developed method for assessing unembodiement on the Internet was tested. The main sample of the study was 809 people (31% of males), mostly university students, aged 17 to 25 years (M=18.73; SD=0.98). Smaller samples were used to study convergent and discriminant validity: 423, 324, 148 and 128 people. Correlations with measures of psychological consequences of Internet use, self-efficacy and life-meaning orientations reported convergent validity, and correlations with measures of intelligence and creativity reported discriminant validity. The results of principal component analysis and confirmatory factor analysis (CFI=0.936, TLI=0.925, RMSEA=0.055, SRMR=0.059) confirm the construct validity of the method, which includes three subscales (Unembodiment as Virtualization, The Preference of the Internet, and Vitality of the Embodied Self) and a general scale (Unembodiment in the Internet). The one-step reliability of the scales varied from 0.7 to 0.9. The scales Vitality of the Embodied Self and The Preference of the Internet had a high level of discrimination, the scale Unembodiment as virtualization ― moderate. The developed questionnaire meets the requirements of validity and reliability and can be used to study the phenomenon of unembodiment on the Internet.

Abstract Background A blended learning environment is multifaceted and widely used in medical education. However, there is no validated instrument for exploring students’ learning in a blended learning environment in medical programs. This study aimed to develop and validate an instrument for exploring how medical students learn in an undergraduate medical program that employs a blended learning approach. Method Using Artino’s seven step approach, we developed a questionnaire to investigate how medical students learn in a blended learning environment. For pilot testing, 120 students completed this 19-item questionnaire. These 19-items were evaluated for construct and convergent validity across an expert medical education panel. Further item testing was analysed with principal component analysis (PCA) with varimax rotation for item reduction and factor estimation. Hence, validity was thoroughly addressed to ensure the questionnaire was representative of the key focus questions. Cronbach’s Alpha was used for item reliability testing, and Spearman’s Rho was used for the correlation between the questionnaire items and the extensively used MSLQ. Hence, validity and reliability were systematically addressed. Results Exploratory Factor analysis identified four factors F1 and F3: Resources: Accessibility & Guidance (14-items), F2: Learning behaviours: Social and Contextual (5-items), and F4: Motivational factors: Intrinsic and Extrinsic Motivation (4-items). Internal consistency and reliability tests were satisfactory (Cronbach’s Alpha ranged from 0.764 to 0.770). Conclusions The resulting Blended Learning Questionnaire (BLQ) was determined to be a reliable instrument to explore undergraduate medical students’ learning in a blended learning environment.

Background/objective The ADL-focused Occupation-based Neurobehavioral Evaluation (A-ONE) can be used to evaluate both performances of activities of daily living (ADL) tasks and neurobehavioural problems that interfere with ADL task performance among clients with neurological disorders. Research studies have demonstrated acceptable psychometric properties of the original version of the A-ONE as well as the Rasch analysed version. The aim of this study was to examine the reliability and validity of the Japanese version of the A-ONE (A-ONE J). Methods Rasch analysis was performed on data obtained from eight different hospitals in Japan on performances of 150 individuals diagnosed with a stroke based on the functional independence (FI) scale items. The rating scale structure was investigated and internal validity and reliability were examined. Unidimensionality of the items was examined by mean square infit values and principal component analysis of residuals. The targeting between person ability and item difficulty was explored, as well as the separation reliability. Finally, psychometric values and item difficulty hierarchies obtained in this study were compared to the original Rasch analysis of the A-ONE. Results The rating scale structure might be improved by collapsing two categories twice (from five categories to three categories). Unidimensionality of the items was obtained for 20 items. Targeting was acceptable, and separation reliability for item calibrations was high and acceptable for people. Conclusion/limitations: This study provides important information regarding the possibilities for revising the ordinal A-ONE J FI Scale, converting it into a unidimensional scale. Further study with increased and more diverse sample is needed.

Medical professionals require adequate abilities to identify others’ emotions and express personal emotions. We aimed to determine the validity and reliability of an empathy measuring tool in medical students for this study. We employed Spreng’s Toronto Empathy Questionnaire (TEQ) as a starting point for this validation. The process was performed in several steps, including an English-Romanian-English translation and a focus group meeting to establish each question’s degree of understandability and usability, with minor improvements of wording in each step. We checked internal and external consistency in a pilot group (n = 67). For construct and convergent validity, we used a sample of 649 students. The overall internal and external reliability performed well, with Cronbach’s alpha = 0.727 and respective ICC = 0.776. The principal component analysis resulted in 3 components: prosocial helping behavior, inappropriate sensitivity, dismissive attitude. Component 1 includes positively worded questions, and components 2 and 3 include negatively worded questions. Women had significantly higher scores than men in convergent validity, but we did not highlight any differences for other demographic factors. The Romanian version of the TEQ is a reliable and valid tool to measure empathy among undergraduate medical students that may be further used in subsequent research.

Abstract Background Conventional median sternotomy is widely used in cardiac surgery, while thoracoscopic cardiac surgery, which is considered to have aesthetic advantages, is being performed increasingly more often in China because patients’ requests for minimally invasive procedures yielding aesthetically pleasing results have significantly increased. Few studies have been conducted to assess surgical scars after cardiac surgery. Compared to the median sternotomy approach, multiple-incision totally thoracoscopic cardiac surgery requires smaller but numerous and scattered incisions. In addition to two working ports on the upper and lower margins of the right breast, an inguinal incision and an axillary incision are made. Therefore, does totally thoracoscopic cardiac surgery truly have aesthetic advantages? This study has the following objectives: (a) to compare median sternotomy cardiac surgery and total thoracoscopic cardiac surgery in terms of the long-term cosmetic outcomes of post-operative scars and (b) to evaluate the effectiveness of the Scar Cosmesis Assessment and Rating scale in combination with the numeric rating scale in the assessment of surgical scars after cardiac surgery. Methods Consecutive patients who visited our institution from January 2019 to May 2019 for cardiac surgery via median sternotomy or the totally thoracoscopic approach and followed up for at least one year were included. Inter-rater reliability, internal consistency and convergent validity were evaluated for the Scar Cosmesis Assessment and Rating scale and the numeric rating scale. Clinical characteristics and the scores of the two scales were compared between the two groups using Student’s t test or the Mann-Whitney U test. Results Thirty-one patients underwent cardiac surgery via the totally thoracoscopic approach, and 42 patients underwent cardiac surgery via the median sternotomy approach. No significant differences were found in the demographic or clinical data between the two groups. The validity and reliability of the two scales were satisfactory. For the Scar Cosmesis Assessment and Rating scale, the median sternotomy group scored statistically significantly higher than did the totally thoracoscopic group on the “overall impression” and “patient question” subscales (P < 0.05). The overall scores of the Scar Cosmesis Assessment and Rating scale and numeric rating scale were statistically significantly different (P < 0.05). Conclusions The Scar Cosmesis Assessment and Rating scale in combination with the numeric rating scale is an effective tool for the assessment of scar aesthetics after cardiac surgery. Surgical scars of totally thoracoscopic cardiac surgery can yield desirable cosmetic outcomes in Chinese individuals, especially in susceptible individuals with a high risk of keloid and hypertrophic scars. Patients with appropriate indications can undergo cardiac surgery with the totally thoracoscopic approach and exhibit a satisfactory scar appearance.
