Purpose: This two-arm, randomized controlled trial was designed to evaluate a computerized cognitive speed of processing (SOP) training known as Road Tour in the generally older group of adults residing in assisted living (AL) and related senior housing. Study aims focused on depression-related outcomes that were observed in earlier SOP studies using Road Tour with younger, home-dwelling seniors. Study design and baseline outcomes are discussed.
Participants and methods: A community-based design engaged AL and related senior living settings as partners in research. Selected staff served as on-site research assistants who were trained to recruit, consent, and train a target of 300 participants from AL and independent living (IL) programs to use the intervention and attention control computerized training. Ten hours of initial computerized training was followed by two booster sessions at 5 and 11 months. Outcome measures included Useful Field of View, 9-item Patient Health Questionnaire, 12-item Centers for Epidemiological Studies Depression scale, 7-item Generalized Anxiety Disorders, Brief Pain Inventory, and SF-36 Health Survey. Assessments occurred before randomization (pretraining) and posttraining, 26 and 52 weeks.
Results: A total of 351 participants were randomized to the intervention (n = 173) and attention control (n = 178) groups. There were no significant differences between groups in demographic characteristics, with the exception of education and reported osteoporosis. There were no significant differences in study outcomes between groups at baseline. Participants in AL had significantly lower SOP and self-rated health, and significantly higher depression, anxiety, and pain when compared to those in IL programs on the same campus.
Conclusion: Compared to earlier SOP training studies using Road Tour, this sample of senior living participants were older, reported more health conditions and poorer overall health, and had lower Useful Field of View scores and greater depressive symptoms at baseline. Moreover, participants in AL had greater health challenges than those in IL.

Depression is a large, escalating public health problem that is the leading cause of disability worldwide, and a major contributor to the overall burden of disease.1 Depression among older adults is often related to other comorbidities including anxiety, pain, medical illness, cognitive decline, and functional impairment, which further contribute to a disability spiral that threatens independence and health-related quality of life (HRQoL).24 Late-life depression is also very costly to individuals and society, with health care costs for depressed elders exceeding that of nondepressed ones in every category.5

The prevalence of late-life depression among older adults who reside in assisted living (AL) and related senior living settings poses important challenges and concerns. Reports suggest 22%–30% of residents in AL and related settings have depressive symptoms,68 but recognition and treatment is often low.912 The homelike features of residential senior living settings have attracted an increasingly physically and mentally frail group of elders,1316 but services have not always kept pace with health-related demands. Many elders receive health care as if they were living at home, a model that relies on the older person to self-manage their health conditions with minimal oversight or assistance. Personal care attendants who provide most services are often not trained to recognize health problems or know what to do in response, especially for mental health issues.10,12 Although support for depression recognition and use of public health approaches like exercise and activity engagement are increasingly available,17 alternative depression prevention and treatment approaches are needed.1820

A computerized cognitive training intervention known as Road Tour has demonstrated considerable promise as a novel depression treatment alternative for older adults living at home. The training intervention, which plays like a game, was developed to improve cognitive function and delay cognitive decline in older adults. However, the Advanced Cognitive Training for Vital Elderly (ACTIVE) study also demonstrated that Road Tour provided protection against worsening depressive symptoms21 and the onset of suspected clinical depression.22 Moreover, data from the Iowa Healthy and Active Minds Study (IHAMS)23 indicated that Road Tour also reduced existing levels of depressive symptoms among community-dwelling participants aged 50–87 years old. Although the mechanism of action for speed of processing training (SOPT) on depressive symptoms is unclear at this time, psychological and biological processes are both possible. First, SOPT has also shown a positive impact on HRQoL,24 which may, in turn, improve mood. As the person feels and functions better, their mood also improves. Second, SOPT may alter neurological function in the brain that influences or controls mood, an explanation that is consistent with neuroplasticity theory and evidence.25 For now, the earlier studies provide considerable support for evaluating the effect of Road Tour on depressive symptoms among the generally older and more functionally challenged group of older adults who have chosen to live in supported residential living environments like AL.

As a self-directed, user-friendly computer “game,” Road Tour overcomes many of the challenges that impede detection and treatment of depressive symptoms in AL settings. There is no need to recognize depressive symptoms, find qualified providers, make referrals, or arrange transportation. The focus on “gaming” avoids potentially stigma-ridden discussions of depression or resistance to “getting help.” Road Tour has no known negative side effects, no known adverse “interactions” with other treatments, and can be used by anyone who has adequate vision and can use a keyboard and mouse. In short, the program offers an important opportunity to promote health and quality of living by interrupting the downward spiral of depression and related disability.

The purpose of this paper is to describe the study methods for a two-arm, randomized controlled trial (RCT) that evaluated Road Tour in AL and related senior living settings. Adaptations to planned approaches are described, along with participant characteristics and baseline outcomes for our three specific aims to evaluate the effect of Road Tour vs attention control on: 1) cognitive processing speed in the AL setting; 2) reducing depressive symptoms and the risk of onset of suspected clinical depression in the AL setting; and, 3) depression-related comorbidities including anxiety, pain, and HRQoL in the AL setting. In this paper we describe the study plan and relevant adaptations, and then describe baseline outcomes.

Materials and methods

The study, Improving Mood in Assisted Living Settings Using a Cognitive Training Intervention (R01 NR-013908; funded by the National Institute of Nursing Research, NINR) was a 5-year, two-arm, parallel, RCT comparing Road Tour training to attention control training using computerized crossword puzzles. Independent Review Board approval was obtained and maintained from the University of Iowa. Written informed consent was obtained from participants. The study was registered with Clinical (NCT 01763216).

Setting recruitment and engagement

A community-based research approach was used to engage AL settings as partners in conducting the research project. The goal was to engage up to 30 AL settings that would each recruit a minimum of 10 older adult participants to achieve the target of 300 total participants. As partners in the research, each organization identified one or more staff members who completed university-sponsored, online human subjects training and acted as on-site research assistants (RAs). These on-site RAs, called Study Liaisons, were trained to recruit, consent, and train participants to use the computer games, conduct computer-based assessments, and facilitate telephone assessments conducted by university team members. Study Liaison preparation used detailed training manuals and fidelity checks performed by the Study Coordinator to assure the integrity of study procedures at partner sites.

Adaptation to setting type

Although AL programs were plentiful, the vast majority were too small to identify 10 participants who would participate, and/or did not have staff resources to support the participatory study approach. Moreover, senior living leaders questioned the logic of involving only AL residents, noting that many residents on the same campus were “one service away” from being classified as “assisted” based on their age, health, and function. Others indicated that they had abandoned policies that required residents to relocate when they needed services. In turn, many older adults living in housing that was defined as “independent living” (IL) on their campus were receiving personal assistance similar to those living in housing defined as AL. As a result, older adults residing in IL apartments on senior living campuses whose AL services were also involved in the study were also invited to participate.

Study participants

All older adults living at partner sites were invited to enroll to maximize generalizability. Inclusion/exclusion criteria included being 60 years old or older, residing in a participating AL, speaking English (the language of Road Tour), and self-report having sufficient visual acuity (with glasses) to use a computer, physical ability to operate a computer keyboard and mouse, and capacity to provide informed consent. Written informed consent was obtained by Study Liaisons at each site using standard procedures that were modeled by university team members to assure both comfort with the process and fidelity to the methods.

Adaptation to participants

We adjusted the lower boundary of our inclusion criteria to 55 years to conform to admission policies in partner settings. This adjustment allowed the Study Liaisons to avoid a sense of discrimination against slightly younger adults living in their communities, and greatly simplified their advertising and recruitment approaches.

Experimental design

Figure 1 contains the CONSORT Flow Chart for the study. Eligible older adults who completed informed consent with Study Liaisons were scheduled for baseline telephone interviews conducted by university team members. All primary outcome measures were collected via telephone interviews, except for the speed of processing measure which was collected on-site by Study Liaisons. Randomization occurred after baseline interviews were completed. Participants were asked to complete 10 hours of training during the first 5–6 weeks, and 4 additional hours of training at 5 and 11 months for a total targeted dose of 18 hours.

Participants were randomized to training groups using block randomization within sites and types of care (AL and IL) to maintain balance across treatment conditions by senior living community and residence type (AL and IL). The study statistician determined the order of assignments using a computer-generated list of random numbers using block sizes of two and four. Participant IDs and assignments were concealed in sequentially numbered opaque envelopes stored in separate bins (one for each site) kept in a locked cabinet within the Study Coordinator’s office.

Assessment and data management

Computer-assisted telephone interviews were used to assess participant characteristics and outcome measures at baseline, and outcome measures again at posttraining (6–8 weeks post-randomization), and at 26 and 52 weeks post-randomization. The speed of processing assessment was administered at the four time points by Study Liaisons using study computers at partner sites. Usage information embedded in the intervention software was sent to research investigators over the internet using secure file encryption protocols. This included the number of minutes played, number of sessions, and the percentage of completing all available exercise sets.

All data collection was monitored by the Study Coordinator. Standard procedures were used for programming computer-assisted telephone interviews software, interviewer training, data entry and editing, as well as database management, updating, reconciliation, data retrieval, and statistical computing, and data security and confidentiality. Codes were written so that missing and implausible values were automatically flagged in real time during the interviews for verification when entered. On-site speed of processing assessments were saved using participant ID numbers and copied to encrypted flash drives that were mailed to the Study Coordinator. Results were printed first and then entered electronically, with the printed originals kept in secure storage. All data were stored on a secure university server that is backed up daily and uses a three-tiered authorization and strong password system to protect data.

Instruments and measures

Speed of processing measures (Aim 1)

Speed of processing was measured using the Useful Field of View (UFOV) PC mouse version. The UFOV is well established, has high reliability and validity, and is the gold standard for measuring visual processing speed.26 It is computer administered and takes 5–7 minutes to complete. Three subtests, stimulus identification, divided attention, and selective attention, are each automatically scored from 17–500 miliseconds (ms), reflecting the shortest exposure time at which the participant could correctly perform each subtest 75% of the time. A composite outcome score of the three subtests ranges from 51 to 1,500 ms, with lower scores reflecting faster speed of processing. Normative data for 2,759 participants aged 65–94 years in the ACTIVE clinical trial indicates that the baseline UFOV composite scores ranged from 86 to 1,500 ms, with a mean of 481.9 ms and standard deviation of 247.5 ms.27

Depression symptoms (Aim 2)

The frequency and severity of depression symptoms were assessed using two self-report scales that were used at each time point. The 12-item version of the Centers for Epidemiological Studies Depression (CESD) scale28 is a shorter version of the original CESD-2029 that has been a gold standard for screening for depression in epidemiological and public surveys, and has very high reliability and validity. The CESD-12 was used in both ACTIVE and IHAMS trials which allows comparison of depression outcomes among participants in this study and subjects in earlier studies. CESD-12 is composed of short statements scored from 0 = rarely or none of the time (<1 day per week) to 3 = all of the time (5–7 days per week) for a score range of 0–36, and has a cut-off score of ≥9 for suspected clinical depression.21,22,30

The 9-item Patient Health Questionnaire (PHQ-9)31 also has very high reliability and validity, is widely used in both research and clinical settings, and performs well in telephone assessments.32,33 The PHQ-9 items reflect the nine DSM-5 diagnostic criteria for major depression34 and are rated from 0 = not at all to 3 = nearly every day for a total score range of 0–27. Established cut-points are: 0–4 = minimal depression; 5–9 = mild depression; 10–14 = moderate depression; ≥15 = severe depression. Scores ≥10 indicate clinically significant depression.35 The PHQ-9 directly assesses two hallmarks of major depression (prominent dysphoria and anhedonia) and is described in a large body of late life depression research.

Depression-related health outcomes (Aim 3)

HRQoL, pain, and anxiety measures used in the study have well-established reliability and validity and age-specific national norms for comparative purposes. HRQoL was measured using the Short Form-36 (SF-36) Health Survey36 at baseline and 52 months to allow direct comparison of 1-year effects with IHAMS and ACTIVE studies. The shorter SF-1237 was used at 6–8 and 26 weeks to approximate SF-36 scores at these intermediate assessments while minimizing respondent burden. Both the SF-12 and SF-36 include the standard single item self-rated health question. Pain was assessed using the Brief Pain Inventory (BPI) that was developed for assessing cancer pain, validated for use in general populations, and is widely used.3840 The BPI includes four pain severity and seven pain interference items that are rated from 0 to 10, an open-ended pain severity item that is rated 0 to 10, two open-ended questions about use of medications and treatments used to treat pain, and one question about pain relief from treatments that is rated 0 to 10. Anxiety symptoms were assessed using the 7-item Generalized Anxiety Disorder (GAD-7) scale41 that rates the DSM-IV42 criteria for GAD on a scale from 0 = not at all to 3 = nearly every day. Cut-points for the GAD-7 are comparable to the PHQ-9, with 0–4 = minimal anxiety; 5–9 = mild anxiety; and ≥10 = clinically significant anxiety.


Personal and health-related characteristics were collected at baseline. Personal characteristics included sociodemographic data (age, race, sex, marital status, education, and income), social support (five items scored on a 5-point scale from 0 = none to 4 = all of the time), and presence of common chronic conditions like high blood pressure, arthritis, heart disease, diabetes, lung disease, as well as anxiety disorder, depression, and current use of depression treatments. Characteristics of partner organizations included number of older adults served, type of programs and services provided, type and number of staff employed, profit/ownership status, and years in operation.

Intervention and attention control training programs


Road Tour is the second-generation SOPT program that was evaluated in ACTIVE (in its MS-DOS format) and used in IHAMS (in its MS Windows format). The training was designed to improve the efficiency and accuracy of visual information processing and the ability to perform complex visual attention tasks. It focuses on improving the speed and accuracy with which users identify and locate visual information using a divided attention format. Over time, the difficulty and complexity of each task is systematically increased as users attain specified performance criteria. Difficulty is increased by reducing visual stimuli duration, adding visual distracters, increasing similarity between target and distracter stimuli, and presenting visual targets over a broader spatial expanse.

To initiate training, the user clicks on the start button. One of two vehicles, either a car or a truck, appears in the center of the screen. Seven distracter stimuli (rabbit crossing signs) and the target sign (Route 66) appear in the periphery. The stimuli (car vs truck, and rabbit crossing vs Route 66 sign) are presented for a specified time and then disappear briefly. A car and truck appear, and the user clicks on the correct target vehicle (car or truck). Then the user selects the circular location where the Route 66 sign had appeared. The training program is tailored to the participant’s performance by maintaining a 75% success rate before increasing the challenge level. As the user progresses, three changes increase the task difficulty: the visual field expands; an increasing number of distracters appear; and the vehicle pairs morph to become more similar and thus more difficult to differentiate.

Adaptation to the intervention

Posit Science Corporation’s CD-ROM based Road Tour training program was used until support was unexpectedly discontinued in August 2014, approximately 17 months after starting enrollment. The web-based replacement, Double Decision, ( was used from 2014 through the end of enrollment in 2015. The training features of Double Decision are the same as Road Tour (as described earlier) (Figure 2). The transition to Double Decision presented short-term delays as we developed new recruitment and training materials for Double Decision and negotiated support for participants already using Road Tour to assure use of one format or the other, but not both by a single participant.

Attention control

Boatload of Crosswords (http://www./ served as the attention control condition. Boatload of Crosswords is one of the oldest and most popular crossword puzzle games commercially available (Figure 3). The software offers the user a choice between three puzzle sizes, three levels of complexity, and varying font sizes. Boatload of Crosswords also provides optional help features, like filling in letters and words, showing incorrect letters or words in red, and solving the puzzle, that minimize frustration levels often associated with puzzle completion. Boatload of Crosswords was chosen for this study because, like Road Tour, it is computerized, very popular and easy to use; many older adults enjoy doing crossword puzzles; and it was successfully used as the attention control condition in IHAMS.

Descriptive statistics including Student’s t-tests and χ2 analysis were used to compare the intervention and attention control groups at baseline and to examine differences based on living setting (AL vs IL). The original analysis plan was to evaluate the three specific aims using each person serving as his/her own control in linear panel analyses43 with GEE to correct for clustering within sites, and, logistic regression GEE models for binary outcomes. Power estimates were based on the results from the earlier IHAMS and ACTIVE studies. Setting a one-tailed a at 0.05 and allowing for 10% attrition, we estimated ≥80% power to detect the improvements in UFOV, 73% power to detect changes in depressive symptoms, and 68% power to detect suspected onset of clinical depression. All analyses were conducted using IBM SPSS Software, v24.

Adaptations to the analysis

Because of the inclusion of participants from IL settings, the analytic approach was altered. We used random-effects general linear mixed models. The dependent variable was the outcome of interest at the time point of interest. The clustering (random-effects) variable was the AL or IL from each participating senior living community. The two main factors were intervention vs attention control and AL vs IL. The interaction between these two factors was included to test for heterogeneity of treatment effects between AL vs IL. Covariates included the outcome of interest at baseline, age, and sex.

Two ad hoc analyses for the first specific aim were also conducted. The first involved expanding the intervention vs attention control from a binary indicator to a trichotomous indicator of Road Tour vs Double Decision vs attention control to test for potential heterogeneity of treatment effects between two speed of processing platforms. The second involved opportunistic dosing testing based on whether the intervention participants completed 8 or more hours of intervention training vs <8 hours.


A total of 31 senior living communities were engaged as partners in the study, including stand-alone AL residences, senior living programs that provided both AL and IL, settings licensed as residential care that provided services similar to AL, and “affordable AL” programs licensed by the state that offer Housing and Urban Development supported housing complimented with services offered by an independent agency. A total of 351 older adults were enrolled in the study, including 178 randomized to the crossword puzzle attention control group and 173 to the cognitive training (Road Tour/Double Decision) intervention group.


Characteristics of participants by group assignment are presented in Table 1. There were no statistically significant differences between the two groups with the exception of education. Participants’ age ranged from 55 to 102, with mean age of 81 years. More than half (63%) were 75 years or older. The vast majority were white, non-Hispanic (98%) women (74%) who lived alone (>75%) and were widowed (53%). Most participants (60%) reported living in the residence two or fewer years, while 21% reported 3–5 years of residence, and 19% reported living in the residence 6 or more years. Overall, the sample was highly educated, with 68% reporting having attended or graduated from college/graduate school. In comparison of the groups, however, the attention control (crossword puzzle) group was significantly more educated. A third of participants did not know/were unsure of their annual income or opted to not report their income. Annual income ranged from $4,000 to $200,000, and more participants reported incomes of less than $25K/yr (23.6%) than incomes of $50K or more (16.6%). Scores for social support suggest participants felt supported most of the time as the overall mean was 14.0 for the five items, with median scores of 3.0 for each item.

Physical health history

There were no statistically significant differences between groups in the report of 16 common physical health conditions, with the exception of osteoporosis that was more frequently reported in the intervention group. Participants reported from 0 to 11 health conditions with an average of 4.5 conditions. Twenty one percent (21%) reported from zero to two, 69% reported three to seven, and 10% reported eight to 11 health conditions. The most commonly reported conditions were arthritis (63%), high blood pressure (61%), chronic pain (43%), back problems and headaches (39%), and problems with hearing and vision (43% each).

Depression and anxiety history

There were also no differences between groups in the report of anxiety and depression. Sixteen percent (16%) of participants reported having anxiety disorder and 23% reported depression or depressive disorder. Of those reporting depression (n = 80), 67.5% indicated they were taking a medication to treat depression and 26% reported other therapies to treat depression, such as self-help books or other supports. Depression and anxiety were highly comorbid (75.4% reported both) and thus correlated (p<0.001).

Study outcome measures

There were no statistically significant differences in study outcomes at baseline, with the one exception (Table 2). Mean scores and percent distributions between the attention control (crossword puzzle) and intervention (Road Tour/Double Decision) groups were comparable for speed of processing (UFOV), depression, anxiety, pain interference, and level of self-rated health. The single difference between groups was mean BPI pain severity scores for the average day (p = 0.005).

Study adaptations

Three changes in the study were also examined at baseline. First, reducing the lower age boundary to 55 resulted in 2.3% of the overall sample being 55 to 59 years of age. Second, comparisons of participants based on their living setting (AL vs IL) indicated that there were statistically significant differences for nearly all main outcomes, as shown in Table 3. Significant differences are observed on the means for UFOV composite scores, the PHQ-9, CESD-12, GAD-7, and levels of self-reported health, but not pain (not shown).

Three main themes related to the study implementation and baseline findings are notable. First, the successful use of a community-based design in which senior living staff were trained to function as RAs makes an important contribution to geriatric research methods. Several key advantages to the design are worthy of highlighting. The approach allowed the study to access residential care settings in a large geographic region that would have not otherwise been feasible to include due to the travel time demands. Engaging staff as RAs meant the “recruiter” already knew the older people in the setting; they did not need to build trust or establish their credibility. Finally, the successful inclusion of the “oldest-old” age group in a “computer study” addresses important biases related to the viability of persons over age 65 years in research studies, and persisting questions about older people’s interest and ability to engage in technology.

The second main theme is that characteristics of participants in the attention control (crossword puzzles) and intervention (Road Tour/Double Decision) group were comparable with three exceptions: educational level, frequency of osteoporosis in the person’s health history, and reports of pain severity for the average day. Thus, the randomization plan appears to have produced equivalent groups. Of equal importance, baseline characteristics of our sample provide important perspectives related to the composition of older adults that are attracted to senior living communities.

An important first consideration is that the average age of the sample (81 years) is considerably higher than earlier SOPT trials that report on depressive symptoms. Participants in the ACTIVE trial were an average of 74 years,22 and the average ages in IHAMS were 57 years (for the group aged 55–64) and 71 years (for the group >65 years) for an overall mean of 61 years for the sample at baseline.44 Consistent with being older, the current sample reported more health conditions (Means = 4.5 vs 2.2 in ACTIVE) and were more likely to report fair or poor health (24% vs 14% in ACTIVE).22

Depression scores on the CESD-12 were also somewhat higher (means = 5.6 vs 3.3 in ACTIVE).22 Overall, about a third of participants reported having depressive symptoms that are considered “subthreshold” as 28.8% experienced mild symptoms on the PHQ-9 and 23.1% had a score of 9 or greater on the 12-item CES-D. Although there is considerable variability in measures and definitions used, these findings are consistent with reports in the literature about depression in AL and other residential settings.8,45,46 Of interest, over a fifth of the sample (n = 80 or 23%) reported having depression, and many of these individuals reported taking medication (68%) or were engaged in a psychosocial intervention (59%). This finding is promising in light of challenges to depression detection and treatment in senior living settings.47

Depression-related factors were also generally low in the sample. The vast majority did not report current anxiety symptoms, and the 11% who did were in the mild range (5–9). Notably, 16% reported having an anxiety disorder, and 43 of 57 (75.4%) who reported anxiety also reported depression. This finding is consistent with reports emphasizing the clinical importance of comorbid anxiety and depression in older adults.4,48 Pain was also generally low; the mean score of 1.5 across the seven pain interference items (activity, mood, walking, normal work, relations with others, sleep, and enjoyment in life) suggests pain had little impact on daily life. Mean scores for the four severity items were consistently low, with the “worst day” being the highest with an average of 2.8 (where 10 is the worst possible pain). And while 24% reported their health as only fair or poor, the vast majority reported good, very good, or excellent health.

A third theme was that successful implementation of the community-based, partnership-style research project involved making changes in the design to best accommodate feedback and needs of partner organizations and “research in the field” challenges. Reducing the planned lower limit of age from 60 years to 55 years was particularly important to senior living communities classified as “affordable AL” that housed low income seniors aged 55 and older. As a result, only 2.3% were in the range not originally planned (55–59 years), and the diversity of participant characteristics was likely enhanced by inclusion of seniors in affordable AL settings. For example, the report of annual income in this sample suggests lower-income individuals were as well represented as the higher-income ones. Second, the change from Road Tour to Double Decision caused some short-term challenges as process issues were confirmed, but the impact on study outcomes appears inconsequential. Last, inclusion of IL programs resulted in differences in study outcomes at baseline that were not fully expected, but are important findings. Participants in AL settings had slower speed of processing (UFOV) scores, higher levels of depression and anxiety, and lower self-rated health compared to those in settings classified as IL, suggesting greater overall health challenges in this group. These findings will be further explored in study-related analyses by specific aim, will inform future research related to the composition of older adults in senior living communities, and hopefully will help shape both daily care practices related to health-related needs and use of cognitive training interventions.


To our knowledge, this is the first RCT to evaluate computerized SOPT in AL settings, and more specifically, the first to focus on depression and depressed-related outcomes associated with SOPT. Our study contributes to the growing body of literature about computerized cognitive training interventions for older adults, and most importantly, to the use of this training among the generally older individuals who have chosen senior living settings as their preferred housing option.
