Trial summary

The ability to find one's way in the world is known as wayfinding. Many older adults who live in senior communities, such as independent living and assisted living residences, find wayfinding very challenging. Often times, these communities are not designed in a way that helps people find their way very easily. Read more about this study

About this study

Official title: A Randomized Controlled Trial of Visual Cues, Signage, and Spaced-Retrieval Education Within Long Term Care Communities to Assist With Wayfinding

The ability to find one's way in the world is known as wayfinding. Many older adults who live in senior communities, such as independent living and assisted living residences, find wayfinding very challenging. Often times, these communities are not designed in a way that helps people find their way very easily. When people cannot find their way, they can get lost, be dependent upon others for getting out and about, or even be afraid to leave their rooms. The purpose of this study is to find out if distinctive signs and decorative elements, along with a special type of education called Spaced-Retrieval education, help residents in these communities find their way more effectively. Twelve senior communities will be assigned by chance to one of three conditions, including: 1) control - no change (the community stays the same); 2) signs and decorative elements enhanced; and 3) signs, decorative elements, and special education added. After agreeing to be in the study, the participants will be asked to find their way to certain places in their community four times over a year. Some people will be asked to participate in educational sessions on wayfinding. In addition, some people will be asked to wear a location tracker, (like a fitness tracker), for four weeks during the year. How well people find their way, along with how much they travel about within the communities, will be compared between the three groups. It is hypothesized that those in the communities with special signs and decorative elements will find their way more effectively than those in the control communities. It is also hypothesized that participants in the communities with the special education intervention will find their way better than those without the education. Finally, it is hypothesized that participants in the communities with signs and cues and education will travel about further distances than those in the control communities. The results of the study can help people who have a tendency to get lost find their way more effectively in their community, and this could result in more independence.

Read the detailed description

The ability to locate and travel successfully to a destination, known as wayfinding, is a significant problem for older adults with cognitive disorders. Relocating to a new residence such as independent or assisted living is a time in which older adults with cognitive problems are most vulnerable to experiencing wayfinding problems. Often these communities are not designed to facilitate wayfinding as they are complex, confusing, and lack distinctiveness. Wayfinding problems can cause individuals' worlds to shrink, leading to a smaller life space (the spatial extent of travel within the community), decreased engagement, and dependence upon others for activities of daily living. The overall goal of the proposed project is to assess the contribution of salient visual cues and Spaced Retrieval (SR) on wayfinding ability and life space in older adults with wayfinding problems who live in senior communities. Salient cues, such as vivid pictures, statues and bright, distinctive signage can make senior residential communities more memorable and distinctive. This study has three specific aims: a) to examine the effect of salient cues with and without SR on wayfinding ability initially and over time in older adults who have wayfinding deficits in senior communities; and b) To determine the effects of salient visual cues and SR on life space; and c) to determine subject characteristics that are most amenable to the intervention; wand which subject characteristics place persons at risk for less responsiveness to the intervention so that the intervention can be appropriately targeted. There are three arms to the clinical trial to which nine care communities will be randomly assigned, including Arm 1 (control; no change to the care community); Arm 2 (colorful and familiar objects and signage placed within the care community); and Arm 3 (Arm 2 cues plus SR). Participants will be individuals within the communities who exhibit problems finding their way. They will be asked to find their way repeatedly to specific destinations over a period of a year. Wayfinding performance, including how fast the participants find the test location and the errors they make compared between study Arms. Life space will also be measured and compared between Arms. It is hypothesized that individuals who are in care communities which are enhanced with salient cues will improve wayfinding when compared to care communities without salient cues. In addition, Spaced Retrieval, which is an evidence-based memory strategy, is hypothesized to positively influence subjects' use of the cues and improve wayfinding performance. Finally, it is hypothesized that wayfinding ability will correlate with life space. The long term goals of this research are to test an evidence based intervention to enhance senior residences so that older adults who have wayfinding problems can more easily learn and remember their environments so that they can maintain independence.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Salient CuesBehavioural

    Salient cues are those that capture the individual's attention. Information that is complex, novel, and difficult to identify takes more processing resources than those that are simple and familiar. Cues such as pictures and wall hangings, along with bright and meaningful signs, will be placed at key decision points within the senior communities.

  • Spaced Retrieval EducationBehavioural

    Spaced Retrieval (SR) is an evidence-based memory strategy that is used to teach individuals with memory loss new or previously known information. In this study, participants in Arm 3 will receive twelve 30-minute educational sessions to help them use the salient cues to find their way.

Study groups in NCT03537729
Study groupRoleWhat they receive
ControlNo interventionThere will be no modifications to décor or signage in the existing care community, and no education on wayfinding. However, subjects will receive the same testing that is provided for the other arms at the designated time periods.
Salient CuesExperimentalSpecial signs and salient cues will be added to the community along the routes being measured for wayfinding. The cues will be comprised of pictures, objects, and signage.
Receives: Behavioral: Salient Cues
Spaced retrieval educationExperimentalThis condition will have signage and cues as in Arm 2 added to the care communities. In addition, a spaced retrieval (SR) memory intervention strategy will be implemented individually for each resident participating in the study to help them remember the presence and function of the environmental wayfinding cues.
Receives: Behavioral: Salient Cues; Behavioral: Spaced Retrieval Education

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adjusted Wayfinding Speed (Feet Per Second)

    Subjects walked three pre-specified routes in the senior living community (simple, moderate, and complex). They were timed as they walked the route using a computer application called DOTT. Rest periods, elevator wait times and errors (wrong turns) were indicated in DOTT as the participant traversed the route. The adjusted wayfinding speed was calculated as the length of the route in linear feet divided by time in seconds the subject took to walk the route, minus rest periods and elevator wait times, plus 120 seconds added per error.

    Measured: Average over months 1, 3, 6, and 12

  2. Wayfinding Accuracy on Simple Route

    Accuracy was measured via proportion of errors, calculated as number of errors made by a participant when walking a pre-specified route divided by number of possible errors on a route. Errors were defined as a subject making a wrong turn at a decision point, or a U-turn in a hallway the wrong direction. Higher value reflects lower accuracy (higher proportion of errors).

    Measured: Average over months 1, 3, 6, and 12

  3. Wayfinding Accuracy on Moderate and Complex Routes

    Accuracy was measured via proportion of errors, calculated as number of errors made by a participant when walking a pre-specified route divided by number of possible errors on a route. Errors were defined as a subject making a wrong turn at a decision point, or a U-turn in a hallway the wrong direction. Higher value reflects lower accuracy (higher proportion of errors).

    Measured: Average over months 1, 3, 6, and 12

Secondary outcomes (1)
  1. Life Space

    Tinetti's Nursing Home Life-Space Diameter scale measures life space on the scale from 0 to 100. Higher scores represent larger life space.

    Measured: Average over months 1, 3, 6, and 12
