The Use and Know-how of ICT-technology in Different Age Groups

When developing various ICT solutions to support people’s well-being, the systems are quite often based on the use of computers or smart phones. However, in different age groups, the skills to use ICT can vary; therefore, not all people can use new technical systems. The aim of this paper was to investigate the selfreported use and know-how of the ICT-technology in different age groups and using the answers to the following questions: ‘how often do you use a desktop computer at leisure?’ and ‘how well do you know the desktop computer?’. The study was carried out as a cross-sectional study by posting the questionnaire to 15,000 working-age Finns. To the question ‘how well do you know the desktop computer?’, 22% of the 2030 age group answered ‘very well’ and 19.1% of the 31-40 age group also replied ‘very well’. In the 41-50 age group, the value was 15.7%, and in the age group 51-60, the value was 10.6%. In the future, when new well-being ICT technology is developed, it is important to take into account that older people do not know as much about ICT as younger people.


INTRODUCTION
With the advance of well-being ICT technology, a variety of new devices or internet solutions have entered the market.The use of computers and other mobile internet or communication devices has increased.For example, according to the Finnish Statistics Office (2008), in 2006, the percentages of computer users among people aged 18-64 years was 100% in upper-level, white-collar workers and students.According to the Finnish statistical office (in spring 2007), 79% of aged 15 to 74 used the internet.However, only 40% of people over the age of 60 used the internet.
The Tampere University of Technology (TUT) has investigated the health effects of new technical equipment using a questionnaire sent to 15,000 working-age Finns.The questionnaire included questions on the familiarity and usage of new technical devices, prevalence of physical and mental symptoms, accidents associated with mobile phone use and an open-ended question on health and new technology (Korpinen et al., 2009).
Our earlier article "Self-reported use of ICT (Information and communication technology) uptake in 2002 and discomfort amongst Finns aged 45-66" presented that less than 30% of Finland's middleaged population use daily desktop computers at leisure.The use of new technical equipment among the group of people who are outside working life was lower than the people's usage in general (4,9% of women outside working life and 13.1% of men outside workig life).(Korpinen and Pääkkönen, 2010).
The amount of daily internet use was 17.5% in all data of Finns aged 45-66, 4.9% of women outside working life and 8.0% of men outside working life.However, 72% of all Finns aged 45-66 used mobile phones on a daily basis, and 59.4% of female respondents outside working life and 60.3% of male respondents outside working life used mobile phones daily.(Korpinen and Pääkkönen, 2010).
The aim of this paper was to investigate the selfreported use of the ICT-technology in different age groups and using the answers to the questions 'how often do you use a desktop computer at leisure?' and "how well do you know the desktop computer?".In addition, some self-reported symptom's influence on the answers will be studied.

Study Population and Questionnaire
The cross-sectional study focused on the workingage population, and the questionnaire was sent to 15,000 Finns between the ages of 18 and 65.The names and addresses of the participants were obtained as a random sample from the Finnish Population Register Centre.The study design was approved by the Ethical Committee of Pirkanmaa Health District, Finland (decision R02099).
The questionnaire included six sections: (1) background information, such as age, gender, marital status, education, occupation, and home county; (2) the familiarity and use of given technical devices at leisure and at work; (3) physical loading and ergonomics; (4) psychological welfare; (5) accidents and close-call situations at leisure or at work and ( 6) an open-ended question regarding 'other observations concerning technology and health'.The details of the questionnaire have been published earlier (Korpinen et al., 2009).
The options for question 16) 'Have you suffered a) sleeping disorders/disturbances, b) depression, during the last 12 months?' was classified so that answers cannot say, not at all and sometimes were coded 0 (no symptoms), and quite often, often and very often were 1 (symptoms).
To compare differences between the age groups we used independent samples Mann-Whitney U-test analyses.

RESULTS
A total of 6,121 responses (3,486 women and 2,625 men) were received, and the average age of the respondents was 41 years old.The amount of the responses to the different age groups were: in the group 2 (21-30) 1229 answers, in the group 3 (31-40) 1305 answers, in the group 4 (41-50) 1375 answers and in the group 5 (51-60) 1479 answers.
Figure 1 shows the answers of all participants to the question 'how often do you use a desktop computer at leisure?' and Figure 2 shows the answers to the question 'how well do you know the desktop computer?'  Figure 3 shows results for the question 'how well do you know the desktop computer?' in different occupational groups.
Figure 3 shows that occupational groups "homework, students" and "upper-level white collar workers" know the desktop computers best.Altogether, 11% of the participants outside working life know desktop computers very well and 29 % of them know it pretty well (Figure 4).The answers of respondents outside working life.(Figure 4).Figures 6 and 7 show the answers of participants who self-reported sleeping disorders/ disturbances or depression, during the last 12 months, to the question 'how well do you know the desktop computer?'Figures 8 and 9 show the answers of participants who did not report sleeping disorders / disturbances or depression, during the last 12 months.To the question 'how well do you know the desktop computer?',22% of the age group 20-30 answered very well and 19.1% of the 31-40 age group also answered very well.In the age group 41-50, the value was 15.7% and in the 51-60 age group, the value was 10.6%.

DISCUSSION
In this questionnaire study, the population was 15,000 working-age persons in Finland, and the amount of responses was 6,121 (41%) (Korpinen et al. 2009).The data was quite large.However the non-response rate was over 50%.The main focuses of the questionnaire were the use of the new technical units (e.g., desktop computers, portable computers, hand-held computers, communicators, internet, mobile phones, electronic marketplaces/ commerce and teletext) and physical/mental symptoms.We asked many questions of the participants' know-how regarding new technology.Therefore, we cannot make any strong conclusions from the data.In addition, this questionnaire data is about 10 years old, which is a long time in consumer technology.For example, the use of the internet has increased in all age groups.However, there can still be differences between different groups.Typically, young persons are more active in using new technology.
In general, about 30% of all participants used desktop computers daily, and 16% of all know the desktop computer very well.Figures 3-8 show that younger persons and persons who typically use computers at work know desktop computers better than others.This is easy to understand.However, it is important to remember, when new well-being technology or technology as part of treatment will be developed, that older persons and persons outside of working life are not always experts in the use of technology.On the other side, older persons are typically persons who need medical treatment and the technology developed for the well-being area.Figures 6-9 show that persons who self-reported depression or sleep disorders / disturbances are as familiar as others with desktop computers and show in practise no difference.So those symptoms are not relevant in the development of the new well-being technology.

CONCLUSIONS
The daily use of desktop computers of all participants was about 30% at leisure in all the data, and 16% know desktop computers very well.To the question 'how well do you know the desktop computer?',22% of the age group 20-30 answered very well and 19.1% of the age group 31-40 also answered very well.In age group 41-50, the value was 15.7%, and in the 51-60 age group, the value was 10.6%.Altogether, 11% of the participants outside working life know desktop computers very well.In the future, it is important to take into account that older people do not know as much about ICT as younger people, and it can influence the use of the new well-being technology.
