Subjective Cognitive Self-Efficacy- Cognitive Failures Questionnaire
A 25-item scale measuring subjective cognition. Participants rate on a scale of 0 (never) to 4 (very often) how often they experience cognitive mistakes and errors in daily tasks.
Time frame: Up to 15 weeks
Objective Cognition- NIH Toolbox Cognitive Battery
20-min computerized battery completed in single sitting on iPad.Domains tested include processing speed and attention, visuospatial ability and memory, verbal learning and memory, and executive functioning and working memory.
Time frame: Up to 15 weeks
Objective Behavioral Sleep - Actigraphy
Actiwatch 2 (Philips Respironics) is a watch-like device that monitors light and motor activity. Device is worn 24 hours a day for 7 days at each assessment, and during 6 weeks of intervention. Data analyzed by proprietary software using 30s epochs. Validated algorithm will be used to obtain sleep onset latency, wake time after sleep onset.
Time frame: Up to 15 weeks
Circadian Rhythm - Morningness-Eveningness Questionnaire
19-item questionnaire that assesses preference for morning, afternoon, and evening activities. Total score reflects degree of "morningness" or "eveningness" type.
Time frame: Up to 15 weeks
Physiological Arousal- Heart Rate Variability
Holter monitor assessed 5 min ECG recordings both at rest and during sleep (with PSG).Time index variables: SDNN (standard deviation of normal to normal heartbeat intervals). Spectral index variables: High frequency (0.15-0.4 Hz), low frequency (0.04-0.15 Hz), very low frequency (below 0.04 Hz).
Time frame: Up to 15 weeks
Subjective Arousal-Global Cognitive Arousal-Perceived Stress Scale
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
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 likert scale from 0 (never) to 4 (very often) how often they felt or thought a specific way. Higher scores correspond to higher perceived stress.
Time frame: Up to 15 weeks
Mood- Beck Depression Inventory (II)
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.
Time frame: Up to 15 weeks
Alcohol Use- Alcohol Use Disorder Test
10-item questionnaire that assess the frequency of alcohol use and problems associated with alcohol use over the past year.
Time frame: Baseline
Mood- State-Trait Anxiety Inventory
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.
Time frame: Up to 15 weeks
Subjective Arousal- Pre-sleep Arousal Scale
Pre-sleep Arousal Scale is a 16-item self-report questionnaire comprising both cognitive and somatic manifestations of arousal.
Time frame: Up to 15 weeks
Subjective Arousal- Arousal Predisposition Scale
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.
Time frame: Up to 15 weeks
Subjective Behavioral Sleep- Electronic Daily Sleep Diaries
Electronic Daily Sleep Diaries. Online diaries completed each morning (\~5 mins) during 1 wk assessment period and 6 weeks of intervention. Diaries measure sleep onset latency, wake time after sleep onset, total sleep time, and sleep quality.
Time frame: Up to 15 weeks
Subjective Behavioral Sleep- Insomnia Severity Index
Brief self-report measure of current perception of insomnia symptom severity, distress and daytime impairment. Commonly used in insomnia treatment outcome research.
Time frame: Up to 15 weeks.
Objective Sleep-PSG
Single night PSG measured sleep stages.
Time frame: Up to 15 weeks
Game-related experience
During the intervention phase for each group, participants will complete "gaming diary" measuring session duration, games played.
Time frame: Up to 6 weeks
