1. Cross-cultural adaptation and validation of the Slovenian version of the Core outcome measures index for low back painMatevž Topolovec, David Vozlič, Nejc Plohl, Rok Vengust, Miha Vodičar, Anne Frances Mannion, 2020, izvirni znanstveni članek Opis: Background:To conduct a cross-cultural adaptation and validation of the Core Outcome Measures Index (COMI) in the Slovenian language, for use in patients with low back pain.
Methods:The English version of COMI was translated into Slovene following established guidelines. Three hundredfifty-three patients with chronic low back pain were recruited from the Orthopedic clinic department of a tertiary care teaching institution. Data quality, construct validity, responsiveness, and test-retest reliability of the COMI were assessed.
Results: The questionnaire was generally well accepted with no missing values. The majority of items exhibited only mild ceiling effects (below 20.0%) and some what more prominent floor effects, which were similar to previousstudies (4.5-78.8%). Correlations with Oswestry Disability Index (ODI) were high (= 0.76 between overall COMI andODI scores), suggesting that the Slovene version of COMI had high construct validity. Additionally, the Slovene version of COMI successfully captured surgical patients' improvement in their low back problem after surgery(overall COMI score change: Z =9.34,p< .001, r =0.53) and showed acceptable test-retest reliability (ICC = 0.86).
Conclusions:The Slovene version of COMI showed good psychometric properties, comparable to those of previously tested language versions. It represents a valuable instrument for the use in future domestic and multicenter clinical studies.

2. Development and validation of the perceived deepfake trustworthiness questionnaire (PDTQ) in three languagesNejc Plohl, Izidor Mlakar, Letizia Aquilino, Piercosma Bisconti, Urška Smrke, 2024, izvirni znanstveni članek Opis: Exposure to false information is becoming a common occurrence in our daily lives. New developments in artificial intelligence are now used to produce increasingly sophisticated multimedia false content, such as deepfakes, making false information even more challenging to detect and combat. This creates expansive opportunities to mislead individuals into believing fabricated claims and negatively influence their attitudes and behavior. Therefore, a better understanding of how individuals perceive such content and the variables related to the perceived trustworthiness of deepfakes is needed. In the present study, we developed and validated the Perceived Deepfake Trustworthiness Questionnaire (PDTQ) in English, Italian, and Slovene. This was done in three phases. First, we developed the initial pool of items by reviewing previous studies, generating items via interviews and surveys, and employing artificial intelligence. Second, we shortened and adapted the questionnaire according to experts’ evaluation of content validity and translated the questionnaire into Italian and Slovene. Lastly, we evaluated the psychometric characteristics via a cross-sectional study in three languages (N ¼ 733). The exploratory factor analyses suggested a two-factor solution, with the first factor measuring the perceived trustworthiness of the content and the second measuring the perceived trustworthiness of the presentation. This factorial structure was replicated in confirmatory factor analyses. Moreover, our analyses provided support for PDTQ’s reliability, measurement invariance across all three languages, and its construct and incremental validity. As such, the PDTQ is a reliable, measurement invariant, and valid tool for comprehensive exploration of individuals’ perception of deepfake videos.

3. Frailty in community-dwelling older people and nursing home residents : an adaptation and validation studySergej Kmetec, Zvonka Fekonja, Adam Davey, Barbara Kegl, Jernej Mori, Nataša Mlinar Reljić, Brendan McCormack, Mateja Lorber, 2024, izvirni znanstveni članek Opis: Aim: The aim of this was to psychometrically adapt and evaluate the Tilburg Frailty Indicator to assess frailty among older people living in Slovenia's community and nursing home settings.
Design: A cross-cultural adaptation and validation of instruments throughout the cross-sectional study.
Methods: Older people living in the community and nursing homes throughout Slovenia were recruited between March and August 2021. Among 831 participants were 330 people living in nursing homes and 501 people living in the community, and all were older than 65 years.
Results: All items were translated into the Slovene language, and a slight cultural adjustment was made to improve the clarity of the meaning of all items. The average scale validity index of the scale was rated as good, which indicates satisfactory content validity. Cronbach's α was acceptable for the total items and subitems.
Conclusions: The Slovenian questionnaire version demonstrated adequate internal consistency, reliability, and construct and criterion validity. The questionnaire is suitable for investigating frailty in nursing homes, community dwelling and other settings where older people live.
Impact:The Slovenian questionnaire version can be used to measure and evaluate frailty among older adults. We have found that careful translation and adaptation processes have maintained the instrument's strong reliability and validity for use in a new cultural context. The instrument can foster international collaboration to identify and manage frailty among older people in nursing homes and community-dwelling homes.
Reporting Method: The Strengthening the Reporting of Observational Studies in Epidemiology checklist for reporting cross-sectional studies was used.
No Patient or Public Contribution: No patient or public involvement in the design or conduct of the study. Head nurses from nursing homes and community nurses helped recruit older adults. Older adults only contributed to the data collection and were collected from nursing homes and community dwelling.

4. The protective role of resilience in the development of social media addiction in tertiary students and psychometric properties of the Slovenian Bergen Social Media Addiction Scale (BSMAS)Mark Žmavc, Andrej Šorgo, Branko Gabrovec, Nuša Crnkovič, Katarina Cesar, Špela Selak, 2022, izvirni znanstveni članek Opis: With the onset of the COVID-19 pandemic, social media became one of the most utilized sources of information relating to the disease. With the increased reliance on social media, the risk of excessive use and the development of social media addiction emerges. The aim of the present study was to explore the psychometric properties of the Slovenian version of the Bergen Social Media Addiction Scale, and to explore how psychological resilience affects social media addiction symptoms directly and indirectly through symptoms of depression, anxiety and mental distress. A large online cross-sectional study was conducted in March 2021 among Slovenian tertiary students (N = 4868). The results showed the high reliability, unidimensionality and criterion validity of the Slovenian Bergen Social Media Addiction Scale. The proposed structural model fit the data well and showed a significant direct positive effect of depression and stress on social media addiction. Moreover, the majority of the negative effects of psychological resilience on social media addiction (87.2%) were indirect, through depression and stress symptoms, whereas resilience had a significantly smaller impact on social media addiction by reducing anxiety symptoms. The overall prevalence of social media addiction symptoms was 4.6%, with females exhibiting higher proportions than men. Additionally, female social media users reported a complete absence of social media addiction symptoms less often compared to males. Future research should further explore the mechanisms behind social media addiction, in order to gain a better understanding of the apparently different risk levels for both genders.

5. Development and validation of the scale for measuring biopsychosocial approach of family physicians to their patientsIrena Makivić, Zalika Klemenc-Ketiš, 2022, izvirni znanstveni članek Opis: Objective While other models focus more on disease and pathophysiology, the biopsychosocial approach emphasises the importance of human health and disease in their fullest contexts. If we are to gain an insight into physical and psychological health needs, and address them quickly and adequately, it is important that we recognise them already at the family practice stage. An approach that assesses needs at patient level could also be seen as patient-centred care, which is one of the key elements of high-quality care. To the best of our knowledge, no scale for measuring the biopsychosocial approach of family physicians has yet been developed.
Design The aim of this study was to develop and validate a scale that measures the biopsychosocial approach of family physicians to their patients through the Delphi and validation process.
Setting The scale was developed through the Delphi study and validated by means of significant statistical methods. Pearson’s correlation coefficient, Cronbach’s alpha, the intracorrelation coefficient, the Spearman-Brown coefficient and exploratory factor analysis were applied.
Participants Five family physicians took part in a brainstorming process and 24 family medicine experts took part in the Delphi study. For the first part of the validation process, there were 31 family medicine trainees in the first group and 32 in the second group. For the last part of the validation process, 164 family physicians completed the scale.
Result Through the Delphi study, 39 final items covering three areas within the biopsychosocial approach were identified. Construct validity was high, with positive linear correlation and good face validity. The intraclass correlation coefficient for test–retest reliability was 0.862. The Spearman-Brown coefficient was the highest (0.931) on an even and odd division. Factor rotation showed that three factors on 35 items explained 39.5% of variances. The final internal consistency on 35 items was 0.911.
Conclusion The developed scale measures the biopsychosocial dimension of family physicians’ work with high Cronbach’s alpha measures and good validity.

6. Measuring young individuals’ responses to climate change : validation of the Slovenian versions of the climate anxiety scale and the climate change worryNejc Plohl, Izidor Mlakar, Bojan Musil, Urška Smrke, 2023, izvirni znanstveni članek Opis: Introduction: While increasing awareness of climate change is needed to address this threat to the natural environment and humanity, it may simultaneously negatively impact mental health. Previous studies suggest that climate-specific mental health phenomena, such as climate anxiety and worry, tend to be especially pronounced in youth. To properly understand and address these issues, we need valid measures that can also be used in non-Anglophone samples. Therefore, in the present paper, we aimed to validate Slovenian versions of the Climate Anxiety Scale (CAS) and the Climate Change Worry Scale (CCWS) among Slovenian youth. Method: We conducted an online survey in which 442 young individuals (18–24 years) from Slovenia filled out the two central questionnaires and additional instruments capturing other relevant constructs (e.g., general anxiety, neuroticism, and behavioral engagement). Results: The confirmatory factor analyses results supported the hypothesized factorial structure of the CAS (two factors) and the CCWS (one factor). Both scales also demonstrated great internal reliability. Moreover, the analyses exploring both constructs’ nomological networks showed moderate positive associations with similar measures, such as anxiety and stress (convergent validity), and very weak associations with measures they should not be particularly related to, such as narcissism (discriminant validity). Lastly, we found that the CAS and, even more so, the CCWS have unique predictive value in explaining outcomes such as perceived threat, support for climate policies, and behavioral engagement (incremental validity). Discussion: Overall, Slovenian versions of the CAS and the CCWS seem to be valid, reliable, and appropriate for future studies tackling young individuals’ responses to climate change. Limitations of the study and areas for future research are discussed.

8. Development and validation of the Work-home-integration questionnaire (WHIQ)Andrea Noja, Bettina Kubicek, Nejc Plohl, Sara Tement, 2022, izvirni znanstveni članek Opis: The boundaries between work and private life are gradually blurring. More and more employees are involved in work during leisure time through cognitions, emotions or behaviours, in both negative and positive ways. This so-called work-home integration (WHI) can, on the one hand, hampers the necessary recovery from work and result in strain but, on the other hand, also restores resources and result in beneficial outcomes. In order to enhance our understanding of WHI and capture all its different forms, we suggest a new conceptualisation and measure of WHI. We therefore developed and validated the Work-Home Integration Questionnaire (WHIQ) in English, German and Slovene simultaneously using two cross-sectional studies (Study 1: N = 848; Study 2: N = 555) and a two-wave longitudinal study with a time lag of 1 month (Study 3: N = 379). Confirmatory factor analysis confirmed a three-factor structure with (1) negative cognitive-affective involvement, (2) positive cognitive-affective involvement and (3) behavioural involvement. Moreover, the WHIQ showed measurement invariance across the three languages and the results provide evidence for convergent, discriminant and incremental validity. Overall, the WHIQ is a reliable, valid and short measure to assess the extent to which employees are involved in work during leisure time.
