Brief summary
Older adults (60+ years of age) who meet criteria for mild cognitive impairment and insomnia will be randomly assigned to cognitive training or trivia training and will complete measures of anxiety, sleep, cognition (objective, self-efficacy), and arousal at baseline, and post-intervention. For cognitive training, participants will be provided with login information to access the computerized training, and will complete 8 weeks (45 mins 3x/week) of cognitive training. For trivia training, participants will receive weekly emails that contain trivia assignments that they will complete for 8 weeks (45 mins 3x/week). We will evaluate short-term (i.e., post-training) effects of the two training conditions on subjective anxiety, sleep, arousal, and subjective and objective cognition.
Interventions
BEHAVIORALCognitive Training
The computerized training exercises and brain games help stimulate cognitive functions while providing real-time monitoring on the evolution of participants' skills.
BEHAVIORALTrivia Training
The computerized trivia training asks participants to answer general questions related to pop culture, science, geography, etc. Participants can use online sources to search for answers and will be provided feedback on their accuracy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Cognition - Computerized Cognitive Tasks | Up to 10 weeks | Complete computerized tasks. These tasks will measure cognitive functions (e.g., processing speed, attention, memory). |
| Subjective Cognitive Self-Efficacy. - Cognitive Failures Questionnaire | Up to 10 weeks | A 25 item questionnaire. Participants rate from 0 (never) to 4 (very often) frequency of cognitive errors. Higher scores indicate lower cognitive self-efficacy. |
| Subjective Behavioral Sleep- Electronic Daily Sleep Diaries | Up to 10 days | Electronic Daily Sleep Diaries. Online diaries completed each morning (\ 5 mins) during the study. Diaries measure sleep onset latency, wake time after sleep onset, total sleep time, and sleep quality. |
| Subjective Behavioral Sleep- Insomnia Severity Index | Up to 10 weeks | Brief self-report measure of current perception of insomnia symptom severity, distress and daytime impairment. Commonly used in insomnia treatment outcome research. |
| Objective Sleep-Watchpat | Up to 10 weeks | Single night objective sleep recording via a wrist worn device. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subjective Arousal- Arousal Predisposition Scale | Up to 10 weeks | Arousal Predisposition Scale is a 12-item inventory that has been designed to measure the degree to which an individual experiences arousal. Higher scores indicate greater predisposition to arousal. |
| Game Engagement Questionnaire | Up to 10 weeks | Questionnaire assessing the experience of the game. |
| Mood-Depression-Beck Depression Inventory-II | Up to 10 weeks | 21-item inventory that asks respondents to rate on a scale of 0 (no depressive feelings) to 3 (most depressive feelings) their feelings towards various aspects of daily living/situations. Higher total scores indicate worse depressive symptoms. |
| Physiological Arousal- Heart Rate Variability | Impact of game related experience will be measured at baseline | CorSense monitor assessed 5 min heart rate recordings both at rest. Time index variables: SDNN (standard deviation of normal to normal heartbeat intervals) |
| Physical Activity - International Physical Activity Questionnaire | Up to 10 weeks | 7- item questionnaire assessing the different kinds of physical activities that the participant does as pat of their everyday life. |
| Personality - Big Five Inventory | Baseline | 10 question assessment measuring personality |
| Computer Proficiency- Computer Proficiency Questionnaire | Baseline | This questionnaire asks about participants' ability to perform a number of tasks with a computer. Will be examined as a covariate. |
| Alcohol Use - Alcohol Use Disorder Test | Baseline | 10-item questionnaire that assess the frequency of alcohol use and problems associated with alcohol use over the past year. |
| Anxiety - State-Trait Anxiety Inventory | Up to 10 weeks | Inventory that asks respondents to rate how true 20 self-descriptive statements (e.g., I feel calm) are on a 4-point scale (1 = not at all, 4 = very much so). Typically, respondents are asked to rate statements according to how they generally feel (trait-anxiety scale) and how they feel in the current moment (state-anxiety scale). Total scores range from 20 to 80, with higher scores indicating greater maladjustment. |
| Game-related experience- Sessions and duration played | Up to 10 weeks | During the intervention phase the cognitive training group will play games and will need to log the days and duration played. |
| Circadian Rhythm- Morningness-Eveningness Questionnaire | Up to 10 weeks | 19-item questionnaire that assesses preference for morning, afternoon, and evening activities. Total score reflects degree of morningness or eveningness type. |
| Perceived Stress- Perceived Stress Scale Subjective Arousal- Perceived Stress Scale | Up to 10 weeks | Perceived Stress Scale is a self-report measure of how life situations are perceived as stressful. The scale consists of 15 items corresponding to everyday situation and participants are asked to rate on a scale from 0 (never) to 4 (very often) how often they felt or thought a specific way. Higher scores correspond to higher perceived stress. |
