Participants were between 74 and 95 years old. Of all participants, ten identified as women and two identified as men (Table 2). Their living situations varied: Three participants lived in villages, six in small towns and three in one bigger town. Five participants lived together with their partner, two lived with their children and grandchildren and five lived alone. Eight participants used walking aids and seven of them were assigned to a care level of the German care insurance.

Note: Participants are listed in order from lowest to highest LSM-Score in ( )
ID = Pseudonym of participants; LSM = life-space mobility; LSM < 60 = restricted LSM (res); LSM > 60= unrestricted LSM; ADL = Activities of Daily Living; iADL= instrumental Activities of Daily Living; number of ADL/iADL limitations is given
Restricted LSM was reported by eight participants including the five who lived alone, and all participants with restricted LSM had four or more ADL/iADL limitations. Participants with balance confidence above 65% had unrestricted LSM except for participant 114. Another exception was participant 147 with the lowest balance confidence of 5% and unrestricted LSM.
We met the coding criterion by Gläser & Laudel as all in all 1045 codes were assigned to the twelve interviews (Gläser and Laudel 2009). Codes of the categories for barriers and resources for LSM overlapped 56 times. From the inductive analysis, a new theme about the ambivalence of social and environmental factors as resources or barriers for LSM emerged.
Resources and barriers for LSM
In total, we assigned more codes of barriers for LSM to six of the interviews whereas more codes of resources for LSM emerged from the other six interviews. Participant number 080, an 83-year-old woman who lives with her husband in a town, was identified as someone who spoke more about barriers than resources for LSM.
Analysis of her interview revealed that most of the barriers were worries about the future as she gave up driving one year ago. For some trips, e.g., visits to medical specialists, she is now dependent on her husband, but she worries about the time when he will have to quit driving too. Her thoughts about adaptive strategies reveal how the interplay of personal factors like knowing how to find information or environmental factors like distance inhibit LSM and the utilization of healthcare resources.
“I was at the station to get information about how the buses run, but they said I should go to the town hall and ask there and there […] you can´t get any information there either. […]. I don’t know where else you can get information about how the buses run. […] When my husband can’t drive a car anymore, […] then we’ll have to get a taxi, but the distance is too short for a taxi to take us there [to the dentist/urologist] […] and then we have to rely on the help of our neighbours.” (ID 080, ll. 43–46).
She is struggling to cope with a possible upcoming loss of independence and to accept the necessity to ask for help from others in the future. She cannot solve the problem of transportation by relying on her own personal abilities (i.e., personal resource) or on her husband (i.e., social resource) or use of public/private transportation services (i.e., environmental resource).
In contrast, participant 147, a 95-year-old woman living together with her grandchildren in a village, has eleven ADL/iADL limitations but an unrestricted LSM mainly speaks about resources for mobility. She sets a clear focus on the use of social and environmental resources like the help of her neighbours or the use of driving services from an association in her village where she is a long-term member. She said: “There are no barriers for me [to get to an event]. All the women who live further away […], they get picked up. […] I always get picked up. […] I just have to call [name of neighbour] in the morning and he says: Yes, I´ll pick you up, I´ll pick you up.” (ID 147, ll.134–137).
The interplay of personal, social and environmental factors for LSM
The following five examples highlight the synergistic interplay of personal, social and environmental factors that fosters LSM, but also how factors interfere, cancel each other out and emerge as a barrier for LSM. First, the importance of shopping as an essential task that also fulfils social needs synergistically is pointed out by participant 059, an 84-year-old man who lives alone in a village and uses a cane and a walker.“I often meet friends when I go out shopping, although there are fewer and fewer of them. We can talk a bit […]. That’s nice because nothing is worse than loneliness. I always need a little bit of companionship.” (ID 059, ll.43–47) His statement sheds light on how the synergistic interplay of his motivation, his environment (supermarket) and social contacts helps him to enhance his mobility outside his home and against loneliness. In a statement before he reveals a contrasting example of how personal attitudes can work as a barrier for LSM. “If necessary, I get into my car because I like to drive and I visit my friends. I built up new contacts after I was alone, and I go and visit them. Of course I don’t stay for too long, one cannot do that. Most of them are couples.” (ID 059, ll. 39–43). He is reluctant to spend too much time with befriended couples as he does not want to bother them, an attitude that hinders him from making longer visits although he can still drive a car to get there on his own as an important personal resource for his LSM.
Second, participant 057, a woman from a small town who lives alone and uses a walker, also highlights the value of shopping as an incentive for LSM outside the house. Her personal strategy to use an attractive environment as a goal for outdoor mobility is undermined by her personal financial situation.“Outside? Oh well, I don´t like that anymore. I need a [defined] goal. And there is a store nearby, where I can go by bus. But some things there are too expensive and I can´t afford to go there that often.” (ID 057, ll. 292–295).
Third, participant 145, a woman, 74 years old, living in a village, with a clearly restricted LSM, low quality of life, low balance confidence and five ADL/iADL limitations, gives the following response to the interviewer’s question about the quality of sidewalks in her village. “Yes, there are sidewalks [in the village]. They modernized the drains and will modernize the sidewalks too. But that is not exactly brilliant. You don´t go out if you don’t see anyone. […] Or you must have someone in mind […] I go out and visit Ms. [Name] to drink coffee and talk a bit, but that rarely happens.” (ID 145, ll. 56–65). This highlights how even a sufficient infrastructure does not automatically facilitate LSM, and social and environmental factors cancel each other out. If the need for social interaction in the form of seeing other people out on the street or visiting a specific person is not fulfilled, there is no other personal motivation to leave the house. Here the social element is the key component in the interplay of factors that foster the decision to stay home or go out and use the existing resource of modernized sidewalks.
Forth participant 005, an 82-year-old woman who lives in a town, is mobile with a walker, has low balance confidence and a highly restricted LSM describes, how her dependency on her care service limits her opportunities to go out: “You know…from breakfast, until the care service gets here the time is too short for me [to go out], it passes quickly […] and until they come back at noon [to take off the compression socks], the time is also too short, because I am busy preparing my lunch. There is always too little time.” (ID 005, ll. 29–32). The care service enables LSM outside the home as they assist the participant to get on her compression socks in the morning. Conversely, the time between the visit of the care service in the morning and the visit in the early afternoon is too short to get active outside her home, especially because the participant sets her personal priorities on preparing lunch.
Fifth, participant 080 demonstrates how a huge garden that needs a lot of care functions as a resource for activities and LSM in the near living environment, but on the other hand limits LSM because the couple is too lazy to extend LSM towards locations within the neighbourhood or town due to physical activities in their garden. “Why don’t we go out? Well sometimes it is the weather or we have something else to do […]. For example in the garden. When we have worked all day in the garden we think that we have spent enough time outside and we can relax.” (ID 080, ll. 138–140).
Ambivalence within social and environmental factors
Within the process of inductive analysis, one new theme about the ambivalence of social and environmental factors was derived. This theme of ambivalence comprises how the same factor can foster LSM as a resource and, at the same time, hinder LSM as a barrier. The following two examples reveal the found ambivalent perceptions within social and environmental factors for LSM.
First, participant 003 is a 78-year-old woman who lives together with her partner in a rural town and uses a walker and an e-mobile. She describes how her partner, who helps her to be mobile with her walker and assists in other ADLs, simultaneously undermines her motivation to go out shopping. “My husband scolds me. “Do you really have to go there?” Yes, sometimes I want to go out and buy some things on my own at [name of drugstore] or somewhere else, shampoo or body lotion or […]. But then I ask my husband to bring it along. [...] I don´t want to talk about it anymore.”
Another example of ambivalent social factors influencing LSM negatively and positively at once is the example of participant number 005, an 82-year-old woman. She stopped riding a bike after she fell once and broke her shoulder two years ago, although she recovered from the fall. She used to go shopping by bike before the fall, and it was a huge source of independence and well-being for her. Her son refuses to help her to ride a bike again. Instead, he takes his mother to the supermarket by car: “I always used go by bike […], but then I fell and broke my right shoulder [...] and then, I was not allowed to ride a bike anymore, but that was two years ago. […] It has no impact anymore. […] But when I ask my son to help me to get my bike ready again he says: “What do you want [with your bike]? Do you want to fall again?”. [...] Yes my son keeps me from riding my bike.” […]. I had a huge basket on my bike where I could put everything […]. And now, when we both go shopping [together] he always tells me to put the groceries in this huge bag. […] I envy everyone who rides a bike.” (ID 005, ll. 55–70). The son’s reaction might be understandable due to safety reasons, but on the other hand, alternatives like using a tricycle to address impaired balance seem not to be discussed, while at the same time, he is a resource for his mother’s LSM as he helps her to visit the supermarket and buy groceries.
Concerning environmental factors, participant 104, a woman with unrestricted LSM, describes how difficult it is to get a taxi in the small town where she lives. There are three different taxi companies in her small town and a taxi can be used as a resource for LSM, but it is almost impossible to get a taxi with only a few days of advanced planning, which makes them unavailable for spontaneous enterprises. “And it is difficult to get a taxi. If […] a woman wants to go to the hairdresser, for example […] you need to schedule it at least four weeks in advance. And then you have to ask them to see if they can fit you in between [other appointments]. […] Well, it is difficult because they [taxis] have a fixed schedule to drive patients to go to [name of two cities] for dialysis. Sometimes they also have to wait for the patient to return.” (ID 104, ll. 61–70).
