Abstract

In dieser Arbeit wird die Markenkommunikation Boschs auf seinem Instagram-Account @boschhomede untersucht. Diese Arbeit versucht folgende Forschungsfragen zu beantworten: 1. Wie nutzt Bosch Elemente der Markenkommunikation auf seinem Instagram-Account? 2. Wie wird die Markenidentität kommuniziert? 3. Wie wirkt sich die Markenidentität auf Boschs strategische Markenkommunikation aus? Ziele der Untersuchung sind zu verstehen, wie Markenidentität durch die Elemente der Markenkommunikation aus sprachwissenschaftlicher Sicht umgesetzt wird, und durch funktionale Analyse der Kommunikationselemente zu untersuchen, welche Möglichkeiten die Kommunikationselemente für Boschs Branding eröffnen. Die Analyse basiert auf der im Theorieteil verwendeten Literatur, insbesondere den dort behandelten drei Ebenen des wirtschaftlichen Corporate Identity Mix-Modells: Symbolik, strategische Kommunikation und Markenverhalten. Während in der Wirtschaft die drei Ebenen leicht zu klassifizieren sind, ist die Klassifizierung in den Sprachwissenschaften nicht eindeutig. Aus sprachwissenschaftlicher Sicht ist strategische Kommunikation der systematische und bewusste Einsatz von Elementen, die zusammen mit ihren unterschiedlichen Funktionen und Zwecken eine Botschaft übermitteln. Daher besteht die Analyse darin, diese Funktionen zu analysieren. Die Analyse besteht aus drei Teilen: Erstens wird die Werbefunktion analysiert; zweitens wird die Kontaktfunktion untersucht und im Anschluss wird die Instruktionsfunktion analysiert. Alle diese Funktionen spielen eine wichtige Rolle für die Forschungsfragen der Arbeit. Das in der Analyse untersuchte Material (Korpus) besteht aus 10 Bildbeiträgen vom Zeitraum 17.10.2022 bis 03.11.2022 und sie werden qualitativ mit einem quantitativen Blick durch die wiederkehrenden Kommunikationselemente untersucht. Als Analysekriterien dienen die drei Textfunktionen und die wiederkehrenden Kommunikationselemente, wie Hashtags, Emojis, Markenname, Bildunterschriften, Textarchitektur (bzw. Posting-Struktur), Slogan und Logo. Die Ergebnisse der Untersuchung zeigen, dass Bosch die drei Funktionen (Werbe-, Kontakt- und Instruktionsfunktion) in seinen Posts nutzt, um zweckgebunden zu kommunizieren, was zusammen mit der strategischen Nutzung der wiederkehrenden Kommunikationselemente darauf abzielt, Kohärenz in den Posts — auch in Bezug auf die gesamte Kommunikationsstrategie der Marke — aufzubauen und letztlich eine starke Markenidentität zu entwickeln. Strategisch setzt Bosch die drei Funktionen u.a. durch die Wiederholung der Kommunikationselemente um, wie z. B. beim umfangreichen und vielseitigen Einsatz von Emoji-Features, insbesondere bei der Aktivierung von Stakeholdern (Kontaktfunktion), bei der Aufwertung durch Werbendes (Werbefunktion) oder bei der Erteilung von Anweisungen (Instruktionsfunktion). Andere Ergebnisse der Arbeit sind es, dass die Marke Bosch strategisch und zweischrittig Hashtags nutzt, um ein möglichst großes Publikum zu erreichen: einerseits markenspezifisch in der Bildunterschrift und andererseits themenspezifisch im Kommentarfeld. Strategisch wird Bosch auch weniger direkte Werbung (Werbefunktion) in seinen Posts nutzen und mehr die Aktivierung von Stakeholdern (Kontaktfunktion), z. B. durch direkte Fragen, Anreden oder Aufforderungen, sowie die Fokussierung auf nicht direktes Marketing, in Form von Ratschlägen (Instruktionsfunktion). Dies dient vorwiegend der Generierung von Aufmerksamkeit, insbesondere solcher, die langfristig durch hilfreiche Tipps dem Verbraucher (Zielgruppe) im Gedächtnis bleibt. Das kommunizierte Kernziel in der Unternehmenskultur der Marke Bosch, die Lebensqualität der Menschen zu verbessern, wird durch die Veröffentlichung von Tipps und Ratschlägen unterstrichen, was als markenbewusste Marketingmethode angesehen werden kann, um dauerhafte und zukunftsorientierte Stakeholder zu gewinnen.

Abstract

BACKGROUND: Body mass index (BMI) shows strong continuity over childhood and adolescence and high childhood BMI is the strongest predictor of adult obesity. Genetic factors strongly contribute to this continuity, but it is still poorly known how their contribution changes over childhood and adolescence. Thus, we used the genetic twin design to estimate the genetic correlations of BMI from infancy to adulthood and compared them to the genetic correlations of height. METHODS: We pooled individual level data from 25 longitudinal twin cohorts including 38,530 complete twin pairs and having 283,766 longitudinal height and weight measures. The data were analyzed using Cholesky decomposition offering genetic and environmental correlations of BMI and height between all age combinations from 1 to 19 years of age. RESULTS: The genetic correlations of BMI and height were stronger than the trait correlations. For BMI, we found that genetic correlations decreased as the age between the assessments increased, a trend that was especially visible from early to middle childhood. In contrast, for height, the genetic correlations were strong between all ages. Age-to-age correlations between environmental factors shared by co-twins were found for BMI in early childhood but disappeared altogether by middle childhood. For height, shared environmental correlations persisted from infancy to adulthood. CONCLUSIONS: Our results suggest that the genes affecting BMI change over childhood and adolescence leading to decreasing age-to-age genetic correlations. This change is especially visible from early to middle childhood indicating that new genetic factors start to affect BMI in middle childhood. Identifying mediating pathways of these genetic factors can open possibilities for interventions, especially for those children with high genetic predisposition to adult obesity.

Abstract

Genetic and early environmental differences including early health habits associate with future health. To provide insight on the causal nature of these associations, monozygotic (MZ) twin pairs discordant for health habits provide an interesting natural experiment. Twin pairs discordant for leisure-time physical activity (LTPA) in early adult life is thus a powerful study design to investigate the associations between long-term LTPA and indicators of health and wellbeing. We have identified 17 LTPA discordant twin pairs from two Finnish twin cohorts and summarize key findings of these studies in this paper. The carefully characterized rare long-term LTPA discordant MZ twin pairs have participated in multi-dimensional clinical examinations. Key findings highlight that compared with less active twins in such MZ twin pairs, the twins with higher long-term LTPA have higher physical fitness, reduced body fat, reduced visceral fat, reduced liver fat, increased lumen diameters of conduit arteries to the lower limbs, increased bone mineral density in loaded bone areas, and an increased number of large high-density lipoprotein particles. The findings increase our understanding on the possible site-specific and system-level effects of long-term LTPA.

6. Lapsen aistitiedon säätelyn tukeminen varhaiskasvatuksen 1–3-vuotiaiden ryhmässä

Author

Aaltonen, S. (Sinikka)

Abstract

Tiivistelmä. Tämä tutkielman tarkoitus oli, selvittää mitä on sensorinen integraatio ja millaista tukea voidaan antaa 1–3-vuotiaiden ryhmässä aistitiedon säätelyn tukemiseen. Sensorinen integraatio kehittyy ihmisille automaattisesti, mutta kehityksen eri osa-alueille voi muodostua ongelmia. Aistitiedon käsittelyn eri osa-alueita voidaan lasten kohdalla tukea. Paras tuki, jonka lapsi saa on hänen luonnollisessa ympäristössä annettavat tuki keinot. Lisäksi kaikkien lasten kohdalla on syytä tukea aistitiedon kehittymistä, sillä se vaikuttaa monilta osin oppimiseen ja arjen toimintoihin. Kandidaatin tutkielmani käsittelee aistitiedon tukemista 1–3-vuotiaiden lasten ryhmässä. Tutkielma on kuvaileva kirjallisuuskatsaus. Tutkimuksen teoreettisena lähtökohtana on A. Jean Ayresin sensorisen integraation teoria. Teoreettisen viitekehyksen keskeiset käsitteet ovat sensorinen integraatio, sensorisen integraation tukeminen ja inkluusio. Tarkastelen sensorisen integraation tukemista 1–3 vuotiailla päiväkoti ympäristössä inkluusion näkökulmasta. Näitä asioita tarkastelemalla syntyi käsitys siitä, miten tärkeä asia sensorinen integraatio ja sen tukeminen ovat. Sensorinen integraatio eli aistitiedon käsittely tapahtuu aivoissamme tiedostamatta. Tämä tarkoittaa sitä, että osaamme käsitellä ja jäsentää kehostamme ja ympäristöstä aistien kautta tulevaa tietoa. Sensorinen integraatio muodostaa perustan älylliselle oppimiselle ja sosiaaliselle käyttäytymiselle. Sensorinen integraation kehittyminen alkaa jo kohdussa ja jatkuu koko elämän. Se muodostaa perustan kaikelle oppimiselle. Tutkielmallani oli kaksi päätavoitetta. Ensimmäisenä halusin kirjallisuuden avulla tuoda tietoutta siitä, mitä sensorinen integraatio on. Toisena tavoitteena oli esitellä konkreettisia tapoja tukea sensorista integraatiota 1–3-vuotiaiden lasten ryhmässä. Kirjallisuudesta nousi esille, että 1–3-vuotiaana luodaan pohja sensoriselle integraatiolle. Varhaiskasvatuksen opettajan yksi tärkeä tehtävä on havainnoida ja arvioida lasten kehitystä ja oppimista. Siten voidaan taata jokaisen lapsen yksilöllisen tuki oppimiseen. Inkluusio tulee tulevina vuosia näyttäytymään tärkeänä osana päiväkoti arkea. Opettajan tärkeä rooli kasvattajana on tiedostaa sensorisen integraation tärkeys ja muodostaa lapselle myönteinen kuva itsestään niin henkilönä, kuin oppijanakin. Lapsen konkreettinen tukeminen pitäisi tapahtua lapsen tutussa toiminta ympäristössä. Keinoina esittelen tutkielmassani muun muassa tuntoaistin tukemisesta sormivärimaalaamisella, tasapainoharjoitukset jumppapalloilla, motoristentaitojen harjoittelu esteradoilla, hienomotorisiaharjoituksia pujottelemalla, kuulonvaraisten taitojen harjoitteleminen kuunteluharjoituksilla ja näönvaraisten taitojen harjoittelua palapelejä tekemällä. Tutkielman aihe on kiistanalainen, mutta tutkielmassa käy ilmi, että sensorisen integraation kehityksen tukeminen on tärkeämpää, kuin tukematta jättäminen. Jatkotutkimushaasteena näen tarvetta tutkia, kuinka hyvin sensorinen integraatio tunnetaan päiväkodeissa ja miten hyvin päiväkodit vastaavat sensorisen integraation tukemiseen ja sen haasteisiin.

Abstract

Learning anatomy in the University of Oulu: Influential factors to success during 2010–2017. Our research covers population of 1398 students from eight different medical and dental courses. We collected exam results from 21 anatomic and 14 histologic practical works and combined them with students’ background information received from the student register of our medical and dental faculties. The background information included students’ name, gender, year of birth, hometown, starting year of medical/dental studies, programme and previous degrees. This research was performed in priority to find possible connections and correlations between the practical work results and the background data. The main purpose was to see if the increasing group sizes have affected on academic performance. We executed statistical analysis by using nonparametric tests Mann-Whitney U-test and Kruskal-Willis’ test for the distributional analysis and for the correlations we used Spearman’s correlation coefficient while our result data was not normally distributed (tested with Kolmogorov-Smirnov). The program we used was IBM SPSS Statistics 22. We found no correlation between the annual student population and the practical work exam results so the increasing group sizes has not affected on academic performance. A good performance in the histologic practical works correlated significantly with similar performance in the anatomic practical works (ρ = 0.409, p

Abstract

The COllaborative project of Development of Anthropometrical measures in Twins (CODATwins) project is a large international collaborative effort to analyze individual-level phenotype data from twins in multiple cohorts from different environments. The main objective is to study factors that modify genetic and environmental variation of height, body mass index (BMI, kg/m(2)) and size at birth, and additionally to address other research questions such as long-term consequences of birth size. The project started in 2013 and is open to all twin projects in the world having height and weight measures on twins with information on zygosity. Thus far, 54 twin projects from 24 countries have provided individual-level data. The CODATwins database includes 489,981 twin individuals (228,635 complete twin pairs). Since many twin cohorts have collected longitudinal data, there is a total of 1,049,785 height and weight observations. For many cohorts, we also have information on birth weight and length, own smoking behavior and own or parental education. We found that the heritability estimates of height and BMI systematically changed from infancy to old age. Remarkably, only minor differences in the heritability estimates were found across cultural-geographic regions, measurement time and birth cohort for height and BMI. In addition to genetic epidemiological studies, we looked at associations of height and BMI with education, birth weight and smoking status. Within-family analyses examined differences within same-sex and opposite-sex dizygotic twins in birth size and later development. The CODATwins project demonstrates the feasibility and value of international collaboration to address gene-by-exposure interactions that require large sample sizes and address the effects of different exposures across time, geographical regions and socioeconomic status.

Abstract

OBJECTIVE: The objective of this study was to analyze how parental education modifies the genetic and environmental variances of BMI from infancy to old age in three geographic-cultural regions. METHODS: A pooled sample of 29 cohorts including 143,499 twin individuals with information on parental education and BMI from age 1 to 79 years (299,201 BMI measures) was analyzed by genetic twin modeling. RESULTS: Until 4 years of age, parental education was not consistently associated with BMI. Thereafter, higher parental education level was associated with lower BMI in males and females. Total and additive genetic variances of BMI were smaller in the offspring of highly educated parents than in those whose parents had low education levels. Especially in North American and Australian children, environmental factors shared by co-twins also contributed to the higher BMI variation in the low education level category. In Europe and East Asia, the associations of parental education with mean BMI and BMI variance were weaker than in North America and Australia. CONCLUSIONS: Lower parental education level is associated with higher mean BMI and larger genetic variance of BMI after early childhood, especially in the obesogenic macro-environment. The interplay among genetic predisposition, childhood social environment, and macro-social context is important for socioeconomic differences in BMI.

Abstract

Background: Genes and the environment contribute to variation in adult body mass index [BMI (in kg/m2)], but factors modifying these variance components are poorly understood. Objective: We analyzed genetic and environmental variation in BMI between men and women from young adulthood to old age from the 1940s to the 2000s and between cultural-geographic regions representing high (North America and Australia), moderate (Europe), and low (East Asia) prevalence of obesity. Design: We used genetic structural equation modeling to analyze BMI in twins ≥20 y of age from 40 cohorts representing 20 countries (140,379 complete twin pairs). Results: The heritability of BMI decreased from 0.77 (95% CI: 0.77, 0.78) and 0.75 (95% CI: 0.74, 0.75) in men and women 20-29 y of age to 0.57 (95% CI: 0.54, 0.60) and 0.59 (95% CI: 0.53, 0.65) in men 70-79 y of age and women 80 y of age, respectively. The relative influence of unique environmental factors correspondingly increased. Differences in the sets of genes affecting BMI in men and women increased from 20-29 to 60-69 y of age. Mean BMI and variances in BMI increased from the 1940s to the 2000s and were greatest in North America and Australia, followed by Europe and East Asia. However, heritability estimates were largely similar over measurement years and between regions. There was no evidence of environmental factors shared by co-twins affecting BMI. Conclusions: The heritability of BMI decreased and differences in the sets of genes affecting BMI in men and women increased from young adulthood to old age. The heritability of BMI was largely similar between cultural-geographic regions and measurement years, despite large differences in mean BMI and variances in BMI. Our results show a strong influence of genetic factors on BMI, especially in early adulthood, regardless of the obesity level in the population.

Abstract

Human height variation is determined by genetic and environmental factors, but it remains unclear whether their influences differ across birth-year cohorts. We conducted an individual-based pooled analysis of 40 twin cohorts including 143,390 complete twin pairs born 1886-1994. Although genetic variance showed a generally increasing trend across the birth-year cohorts, heritability estimates (0.69-0.84 in men and 0.53-0.78 in women) did not present any clear pattern of secular changes. Comparing geographic-cultural regions (Europe, North America and Australia, and East Asia), total height variance was greatest in North America and Australia and lowest in East Asia, but no clear pattern in the heritability estimates across the birth-year cohorts emerged. Our findings do not support the hypothesis that heritability of height is lower in populations with low living standards than in affluent populations, nor that heritability of height will increase within a population as living standards improve.

Abstract

Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based pooled analysis of 45 twin cohorts from 20 countries, including 180,520 paired measurements at ages 1-19 years. The proportion of height variation explained by shared environmental factors was greatest in early childhood, but these effects remained present until early adulthood. Accordingly, the relative genetic contribution increased with age and was greatest in adolescence (up to 0.83 in boys and 0.76 in girls). Comparing geographic-cultural regions (Europe, North-America and Australia, and East-Asia), genetic variance was greatest in North-America and Australia and lowest in East-Asia, but the relative proportion of genetic variation was roughly similar across these regions. Our findings provide further insights into height variation during childhood and adolescence in populations representing different ethnicities and exposed to different environments.

Abstract

We analyzed birth order differences in means and variances of height and body mass index (BMI) in monozygotic (MZ) and dizygotic (DZ) twins from infancy to old age. The data were derived from the international CODATwins database. The total number of height and BMI measures from 0.5 to 79.5 years of age was 397,466. As expected, first-born twins had greater birth weight than second-born twins. With respect to height, first-born twins were slightly taller than second-born twins in childhood. After adjusting the results for birth weight, the birth order differences decreased and were no longer statistically significant. First-born twins had greater BMI than the second-born twins over childhood and adolescence. After adjusting the results for birth weight, birth order was still associated with BMI until 12 years of age. No interaction effect between birth order and zygosity was found. Only limited evidence was found that birth order influenced variances of height or BMI. The results were similar among boys and girls and also in MZ and DZ twins. Overall, the differences in height and BMI between first- and second-born twins were modest even in early childhood, while adjustment for birth weight reduced the birth order differences but did not remove them for BMI.

Abstract

Small craft sector firms are struggling to survive in an environment where large multinational\ud companies produce similar kinds of products in higher volumes and cheaper prices. The\ud surviving of small firms calls for creative thinking. There are many different ways to react to\ud these challenges.\ud Those of them that have been trading for decades have a quality that no newcomer has: their\ud history and knowledge. This quality is seldom fully valued or exploited by the companies.\ud However, more efficient exploitation of the enterprise cultural heritage could enhance the\ud competitiveness of long established small businesses - especially today, when sustainability,\ud authenticity, innovativeness and traditions are highly valued among many consumers\ud worldwide (Feagan, 2007, Sedera et al., 2004, Halweil, 2002). These assets can be vital for\ud surviving for long established companies.\ud Heritage can be used as an asset, which can have new meanings in new contexts and eras.\ud Therefore, it can be used to serve contemporary purposes. Enterprise cultural heritage’s both\ud cultural and economic values have become more visible recently. The concepts of heritage\ud production and heritage as commodity have been introduced. First venues for this\ud commercialization have been museums, travel and food industry. (Nic Craith, 2007, Kockel,\ud 2007). The cultural heritage includes both the intangible assets, such as the practices,\ud representations, expressions, knowledge and skills - as well as the tangible assets which\ud includes objects, artefacts and cultural spaces associated therewith (Unesco, 2003, Nic Craith,\ud 2007). The concept of ECH aims to bring the concept of cultural heritage now closer to the\ud everyday business practices. ECH is an innovative and complex concept combining the\ud company’s own history and creations with the potential to transform information and\ud materials into “extended products & services”.\ud The aim of the paper is twofold - both empirical and theoretical. On one hand, the\ud applicability of the resource-based view is tested with case studies and on the other hand, the\ud theoretical foundations of this novel concept of ECH are consolidated. This paper aims to\ud answer the questions: how is the Enterprise Cultural Heritage exploited in the companies\ud studied and does the exploitation of ECH create sustained competitive advantage for these\ud companies (evaluated with the VRIO framework). In the conclusions and implications both\ud the theoretical and policy implications of the study are discussed, as well as how a conscious\ud use of ECH might help the long established companies to survive.

Abstract

Objectives: This paper aims to introduce a novel concept of Enterprise Cultural Heritage (ECH) which combines the company’s own history and creations with the potential to transform information and materials into “extended products & services”. Firstly, the objective is to explore the skills needed in established craft sector Small and Medium sized Enterprises (SMEs) to fully exploit the potentials of ECH and thus gain a competitive advantage. Secondly, we’ll investigate the ECH Skills Gap and how it could be closed.\ud \ud Prior Work: The concept of ECH draws insight from a broad range of literature including: Marketing, Product Development & Innovation, Organisational Culture and Knowledge Management. However, to date, this has achieved precious little attention in the academic literature as well as practitioners focused training courses. ECH can be regarded as part of company’s knowledge capital, but as it has been argued the exploitation of knowledge of an organisation, resides not in the knowledge itself, but in the ways that knowledge is used and re-used.\ud \ud Approach: The study is exploratory in nature. It introduces a new concept and reveals its potentials and usage in everyday business. It is based on telephone surveys of established (over 40 years old); craft sector SMEs in five EU countries. Some 370 companies, identified using standard commercial directories, were approached. A total of 77 interviews were completed.\ud \ud Results: The results of the survey reveal that almost half of the companies interviewed were lacking ECH skills. The survey identified particular ECH related subject such as: brand management, heritage management, change management and Intellectual Property Rights (IPR) as the most vital for effective ECH management. There was a lack of skills mostly on the areas of ICT/heritage management and marketing\ud among the interviewees.\ud \ud Implications: Both the training and policy implications of the study are discussed, e.g., how to promote more effective usage of ECH in established craft sector SMEs. The study is part of a European project, which explores and establishes the field of Enterprise Cultural Heritage (ECH). Practical implications include training material development to better enable SMEs in exploiting their ECH and improving the quality of vocational education and training practices.\ud \ud Value: The ECH concept is important as it is relevant to large number of SMEs, especially to older craft sector\ud companies. Sustainability, authenticity, innovativeness and traditions are highly valued among many consumers worldwide.

Abstract

Objectives: Identifying a truly unique source for innovation and differentiation in order to sustain competitive advantage is a major challenge for managers of enterprise when designing and developing their product/service range. The objectives of this paper are to a) explore the concept of Enterprise Cultural Heritage (ECH) Management as a source of competitive advantage and b) illustrate how it can be utilised using three examples of ECH use in Small and Medium-sized Enterprise (SME). \ud \ud Data and Methods: Through an international and multidisciplinary research team from five European countries (the Czech Republic, Finland, Greece, Italy and the UK) an action research study was conducted. The target sample was craft sector enterprises, which have been in existence for over 40 years. At the diagnostic stage of action research, training needs analysis of 60 Small and Medium-sized Enterprises (SMEs) based in the five countries was conducted. At the therapeutic stage of research, the survey results were translated into SME training needs and free online training material was developed and tested with targeted SMEs.\ud \ud Results: The results of the diagnostic stage of our action research indicate a strong need for training towards utilisation of enterprise cultural heritage within SMEs in order to innovate and differentiate. Several exemplars of good practice were highlighted and a strong correlation between a high level of heritage management and the competitiveness of an enterprise was identified. As part of the therapeutic stage of research, a management method has been proposed and used for the development of online training material in the areas of brand management, change management, heritage management and Intellectual Property (IP) management. \ud \ud Conclusions: Enterprise Cultural Heritage management is recognised as an important practice for enterprises that wish to sustain their competitive advantage based on their heritage. Enterprise Cultural Heritage comprises both tangible and intangible cultural assets, these offer an emotional connection with customers and hence require preservation and optimisation in order to gain commercial as well as historic benefits for the enterprise. There is a need for both management as well as heritage disciplines to recognise the need to work together and educate enterprises about the opportunities and options of innovations.

Abstract

Enterprise Cultural Heritage (ECH) is an innovative and complex concept combining the company’s own history and creations (technical contents, industrial design, organization, marketing, etc.) with the potential to transform information and materials into “extended products & services”. This paper drawing on the results of a review of the literature and a survey of 60 Small and Medium-sized Enterprises (SMEs) based in four European Union (EU) countries argues that effective ECH management can increase creativity in production and innovate knowledge management skills. The current study makes two distinct contributions: Firstly, it introduces the ECH concept and embeds it in a broad body of literature. Secondly, it provides evidence-based insights into the potential impact of using ECH in order to enhance competitiveness.

Abstract

Provision of medication information may improve adherence and prevent medication related problems. People with mental health disorders commonly receive less medication counselling from pharmacists than people with other common long term and persistent disorders. Objective: The objective of this study was to compare and contrast barriers pharmacy students perceive toward providing medication counselling for people with mental health disorders in Australia, Belgium, Estonia, Finland, India and Latvia. Methods: Barriers identified by third-year pharmacy students as part of the International Pharmacy Students´ Health Survey were content analysed using a directed approach. Students´ responses were categorised as pharmacist related, patient related, health-system related, or social or cultural related. Quantitative data were analysed using SPSS version 14.0. Results: Survey instruments were returned by 649 students. Of the respondents, 480 identified one or more barriers to medication counselling for people with mental health disorders. Patient related factors accounted for between 25.3% and 36.2% of barriers identified by the pharmacy students. Pharmacist related factors accounted for between 17.6% and 45.1% of the barriers identified by the pharmacy students. Students in India were more likely to attribute barriers to pharmacist and social and cultural related factors, and less likely to health-system related factors, than students studying in other countries. Conclusion: The nature of barriers identified by pharmacy students differed according to the country in which they studied. Undergraduate and postgraduate pharmacy education programs may need to be amended to address common misconceptions among pharmacy students. La provisión de información sobre medicamentos puede mejorar la adherencia y prevenir problemas relacionados con los medicamentos. Las personas con desordenes mentales normalmente reciben menos consejos sobre medicación de los farmacéuticos que la gente con otras enfermedades comunes de larga duración. Objetivo: El objetivo de este estudio fue comparar y contrastar las barreras que los estudiantes de farmacia perciben hacia proporcionar consejos de medicación para personas con desordenes mentales en Australia, Bélgica, Estonia, Finlandia, India y Letonia. Métodos: Se realizó un análisis de contenido de abordaje directo de las barreras identificadas pro estudiantes de tercero de farmacia como parte de la Encuesta de Salud de los Estudiantes de Farmacia. Las respuestas de los estudiantes se categorizaron como relativas al farmacéutico, relativas al paciente, relativas al sistema de salud, o relativas a aspectos sociales o culturales. Los datos cuantitativos se analizaron utilizando un SPSS versión 14.0. Resultados: Las encuestas fueron retornadas por 649 estudiantes. De los respondentes, 480 identificaron una o más barreras al consejo sobre medicación para personas con desordenes mentales. Los factores relativos al paciente representaron entre el 25,3% y el 36,2% de las barreras identificadas por los estudiantes. Los factores relativos al farmacéutico alcanzaron el 17,6% a 45,1% de las barreras identificadas. Los estudiantes de India eran más proclives a atribuir barreras al farmacéutico y a los aspectos sociales y culturales, y menos a los factores del sistema de salud que los estudiantes de otros países. Conclusión: La naturaleza de las barreras identificadas por los estudiantes de farmacia difirió entre los países estudiados. Los programas de formación pre y postgraduados en farmacia podrían tener que corregirse para encarar los malos entendidos comunes entre los estudiantes de farmacia.

Abstract

Background: Healthcare professionals commonly exhibit negative attitudes toward people with mental disorders. Few international studies have sought to investigate the determinants of stigma. Objective: To conduct an international comparison of pharmacy students' stigma towards people with schizophrenia, and to determine whether stigma is consistently associated with stereotypical attributes of people with schizophrenia. Method: Students (n = 649) at eight universities in Australia, Belgium, India, Finland, Estonia and Latvia completed a seven-item Social Distance Scale (SDS) and six items related to stereotypical attributes of people with schizophrenia. Results: Mean SDS scores were 19.65 (± 3.97) in Australia, 19.61 (± 2.92) in Belgium, 18.75 (± 3.57) in India, 18.05 (± 3.12) in Finland, and 20.90 (± 4.04) in Estonia and Latvia. Unpredictability was most strongly associated with having a high social distance in Australia (β = -1.285), the perception that people will never recover in India (β = -0.881), dangerousness in Finland (β = -1.473) and the perception of being difficult to talk to in Estonia and Latvia (β = -2.076). Unpredictability was associated with lower social distance in Belgium (β = 0.839). Conclusion: The extent to which students held stigmatizing attitudes was similar in each country, however, the determinants of stigma were different. Pharmacy education may need to be tailored to address the determinants of stigma in each country. [ABSTRACT FROM AUTHOR]
