Assessment Interview

Background: Despite the importance of effective assessment and treatment of negative symptoms among patients with psychosis, no validated instruments are available in the Republic of North Macedonia. The aim of this paper was to explore psychometric properties, namely factorial structure, internal consistency, convergent and discriminant validity of the Clinical Assessment Interview for Negative Symptoms (CAINS).Subjects and methods: In this cross-sectional study 82 outpatients diagnosed with psychosis (64 with schizophrenia and 18 with bipolar disorder; female=34, mean age=41.05±10.09) were assessed.Results: The exploratory factor analysis revealed two factorial structure of the negative symptoms as measured by the CAINS, i.e. ‘expression and motivation’ and ‘pleasure’. Two items aimed to measure motivation for family relations and motivation for work/school activities loaded on the expression factor instead on motivation and pleasure factor which differs from the original version of the CAINS. Convergent validity was proven by positive relationship to negative symptoms as measured by the BPRS. Positive, but weak correlation with BPRS positive symptoms demonstrated its discriminant validity. Internal consistency of overall CAINS scale and its two subscales was very high.Conclusion: The CAINS can be used to assess negative symptoms in individuals with psychosis in the Macedonian clinical context. Consequently, this work can provide a foundation for further clinical advancement and research of negative symptoms in Macedonian healthcare.

Abstract Background Limited diffusion and utilization of health technology has greatly halted the improvement of resource integration and healthcare outcomes. However, the dynamic mechanism of health technology diffusion in the context of integrated care system (ICS) remained largely unknown. The purpose of this study was to develop and validate the scale on Dynamics of Health Technology Diffusion in Integrated Care System (DHTDICS) for providing instruments to investigate the health technology diffusion in ICS.Methods The scale was initially designed on the basis of the proposed model developed from previous research. And it was validated in a cross-sectional questionnaire survey. Exploratory factor analysis was used to assess domains in the questionnaire, and analyzed factorials, internal consistency and validity of the questionnaire. Results Reliability analysis revealed excellent internal consistency, as the value of Cronbach’s alpha all greater than 0.80 for four of the domains in this study. An acceptable validity was confirmed through tests of construct validity, convergent validity and discriminant validity. With respect to the potential domains and dimensions that DHTDICS contributes, the results highlight the existence of 4 domains: personal beliefs, technical drivers, organizational readiness and external environment.Conclusions The findings of this study will be capable to serve as a valid instrument to measure health technology diffusion, and be also helpful in developing future intervention strategies to promote the health technology diffusion in ICS.

The aim of this monocentric cross-sectional study was to evaluate the psychometric characteristics of the Italian version of the Level of Exposure-Dental Experiences Questionnaire (LOE-DEQ) in an Italian sample of 253 dental patients ranging from 18–80 years of age. The LOE-DEQ assesses 16 potential dental distressing experiences and 7 general traumatic life events through 4 subscales: (1) dentists’ behaviour and patients’ emotions (DBPE); (2) distressing dental procedures (DDP); (3) other distressing dental events (ODDE); and (4) general traumatic events (GTE). Confirmatory factor analysis showed that the original 4-factor model had adequate fit to the data obtained from the Italian sample. Criterion validity was partially confirmed as only DBPE and DDP positively correlated with dental anxiety. Similarly, convergent validity was also partially confirmed as DBPE, DDP, and ODDE correlated with negative beliefs towards the dentist and the dental treatment. Discriminant validity was fully confirmed, as all correlations were below 0.60. Finally, DDP was the factor most associated with high dental anxiety. This study offers evidence of the reliability and validity of the LOE-DEQ in the Italian context, providing Italian researchers and dentists with a tool to assess dental and general distressing experiences in dental patients.

Collective Empowerment

Background The role of online health communities (OHCs) in patient empowerment is growing and has been increasingly studied in recent years. Research has focused primarily on individualistic conception of patients’ empowerment, with much less attention paid to the role of OHCs in the development of patients’ collective empowerment. Although OHCs have immense potential for empowerment that goes beyond the individual, the concept and scale of collective empowerment in OHCs have not yet been developed or validated. Objective This study aimed to develop an instrument for measuring collective empowerment in online health communities (CE-OHC) and to test its quality by investigating its factorial structure, reliability, construct validity, and predictive validity. Methods The CE-OHC scale was developed according to a strict methodology for developing valid and reliable scales. An initial set of 20 items was first tested in the pilot study conducted in 2016 using a sample of 280 registered users of Slovenia’s largest OHC. A refined version with 11 items was tested in the main study conducted in 2018 on a random sample of 30,000 registered users of the same OHC. The final sample comprised 784 users. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to investigate the factorial structure, discriminant validity, and convergent validity of the scale. Cronbach alpha coefficient was used to determine the CE-OHC scale’s internal consistency. To establish the predictive validity, ordinary least squares regression was performed to test the role of CE-OHC in users’ civic participation. Results The EFA resulted in a two-factor solution, and the two factors—knowledge of resources and resource mobilization for collective action—together explain 63.8% of the variance. The second-order CFA demonstrated a good fit to the data (root mean square error of approximation=0.07) and the scale had a good internal consistency (alpha=.86). Although evidence of the scale’s convergent validity was partially provided, discriminant validity of the scale remained unconfirmed. Overall, CE-OHC was confirmed to be a predictor of users’ civic participation, but the influence was somewhat weak and inconsistent across two subscales. Conclusions The proposed CE-OHC scale is a reliable and relatively valid instrument and serves as a good baseline to advance the measurement of collective empowerment in OHC contexts. This is the first scale developed for this purpose, and future research should focus on the development of a clear nomological network of the collective empowerment construct in relation to the OHC settings.

Objective: This study examined the construct validity of the Enfranchisement scale of the Community Participation Indicators. Design: We conducted a secondary analysis of data collected in a cross-sectional study of rehabilitation outcomes. Subjects: The parent study included 604 community-dwelling adults with chronic traumatic brain injury, stroke, or spinal cord injury. The sample had a mean age of 64.1 years, was two-thirds male, and included a high proportion of racial minorities ( n = 250, 41.4%). Main measures: The Enfranchisement scale contains two subscales: the Control subscale and the Importance subscale. We examined correlations between each Enfranchisement subscale and measures of participation, environment, and impairments. The current analyses included cases with at least 80% of items completed on each subscale (Control subscale: n = 391; Importance subscale: n = 219). Missing values were imputed using multiple imputation. Results: The sample demonstrated high scores, indicating poor enfranchisement (Control subscale: M = 51.7; Importance subscale: M = 43.0). Both subscales were most strongly associated with measures of participation (Control subscale: r = 0.56; Importance subscale: r = 0.52), and least strongly associated with measures of cognition (Control subscale: r = 0.03; Importance subscale: r = 0.03). The Importance subscale was closely associated with depression ( r = 0.54), and systems, services, and policies ( r = 0.50). Both subscales were associated with social attitudes (Control subscale: r = 0.44; Importance subscale: r = 0.44) and social support (Control subscale: r = 0.49; Importance subscale: r = 0.41). Conclusions: We found evidence of convergent validity between the Enfranchisement scale and measures of participation, and discriminant validity between the Enfranchisement scale and measures of disability-related impairments. The analyses also revealed the importance of the environment to enfranchisement outcomes.

Abstract Background Generalized Anxiety Disorder (GAD) is under-investigated in people living with HIV/AIDS from sub-Saharan Africa. In part, this is due to paucity of culturally appropriate measures for GAD which are psychometrically robust. This study aimed to evaluate the reliability, factorial structure, and validity of Swahili version of the 7-item GAD questionnaire (GAD-7) among adults living with HIV. Study design Descriptive cross-sectional study. Methods 450 adults receiving comprehensive care from an HIV specialized clinic in Kilifi County, coastal Kenya, were consecutively recruited. Swahili versions of GAD-7, Patient Health Questionnaire (PHQ-9) and a 12-item HIV stigma scale were administered alongside measures of psychosocial and health-related characteristics. Internal consistency, test–retest reliability, factorial structure, convergent validity, and discriminant validity of Swahili GAD-7 were examined using Cronbach’s alpha (α), intra-class correlation coefficient (ICC), Confirmatory Factor Analysis (CFA), Pearson’s correlation, and analysis of covariance (ANCOVA), respectively. Results Internal consistency of Swahili GAD-7 was good, α = 0.82 (95% CI 0.78, 0.85). Its test–retest reliability (2 weeks apart) was acceptable, ICC = 0.70 (95% CI 0.55, 0.81). A confirmatory analysis of a one-factor solution indicated an excellent fit to the hypothesized structure (RMSEA = 0.00 [95% confidence interval 0.00, 0.05], CFI = 1.00, TLI = 1.00). Multi-group CFA substantiated factorial invariance for sex and age for the one-factor structure of Swahili GAD-7. Scores of GAD-7, Swahili version, significantly correlated with those of PHQ-9 (r = 0.73; p < 0.001) and the HIV stigma scale (r = 0.36; p < 0.001) suggesting good convergent validity. Statistically significant differences were observed between participants on first-line antiretroviral therapy compared to those on second-line treatment (F [1, 441] = 5.55, p = 0.02) indicative of good discriminant validity of Swahili GAD-7. Conclusion GAD-7 Swahili version retained its original unidimensional latent structure with good psychometric properties among adults living with HIV from Kilifi, Kenya. It can be used to identify symptoms of GAD in similar research settings. However, to confidently identify those in need of mental health treatment or referral services in HIV primary care clinics, more research on the validity of Swahili GAD-7 is needed especially its discriminant validity and diagnostic accuracy at different cut-off scores.

Objective. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Dental Fear Survey (DFS), previously translated to the Brazilian Portuguese language and validated.Methods. A cross-sectional study with 1,256 undergraduates from the city of Belo Horizonte, Brazil, was carried out. The DFS and a questionnaire about previous dental experiences were self-administered. Data analysis involved descriptive statistics, principal components analysis (PCA), confirmatory factor analysis (CFA), internal consistency and test-retest reliability, and construct, discriminant, and convergent validity.Results. PCA identified a three-factor structure. CFA confirmed the multidimensionality of the Brazilian version of the DFS. A modified model of the Brazilian version of the DFS fits better than the hypothesized model. The Cronbach’s alpha coefficient for the total DFS scale was 0.95.Conclusion. The DFS demonstrated acceptable construct validity, convergent validity, and discriminant validity. These results supported the reliability and validity of the DFS among Brazilian undergraduates.

Abstract Background: Up to our knowledge, there is currently no psychometrically validated Hungarian scale to evaluate nurses’ knowledge about infection prevention and control (IPC) practices. Thus, we aim in this study to assess the validity and reliability of the infection control standardized questionnaire Hungarian version (ICSQ-H).Methods: A cross-sectional, multisite study was conducted among 591 nurses in Hungary. The original ICSQ including 25 items was translated into Hungarian. A panel of four experts assessed the content validity of the questionnaire by calculating the item content validity index and scale content validity index. Then, construct validity was evaluated using principal component analysis and confirmatory factor analysis. The goodness of fit for the model was measured through fit indices. Convergent validity was assessed by calculating the average variance extracted. Additionally, discriminant validity was evaluated by computing the spearman correlation coefficient between the constructs. Finally, the interitem correlations, the corrected item-total correlations, and the internal consistency were calculated.Results: Content validity of the questionnaire was established with 23 items. The final four-construct ICSQ-H including 10 items showed a good fit model. Convergent validity was met except for the alcohol-based hand rub (ABHR) construct, while discriminant validity was met for all constructs. The interitem correlations and the corrected item-total correlations were met for all constructs but, the internal consistency of ABHR was unsatisfactory due to the low number of items.Conclusions: The results did not support the original three-factor structure of the ICSQ. However, the four-factor ICSQ-H demonstrated an adequate degree of good fit and was found to be reliable. Based on our findings, we believe that the ICSQ-H could pave the way for more research regarding nurses’ IPC knowledge to be conducted in Hungary. Nevertheless, its validation among other healthcare workers is important to tailor effective interventions to enhance knowledge and awareness.
