Attentional Bias

"Subjects will complete an attentional bias task. The number of inhibitory failures (i.e., commission errors) to no-go targets following methamphetamine-related stimuli will be used to evaluate attentional bias (range 0 - 1: greater values represent greater number of errors committed). Commission errors are when you response (i.e., press the corresponding key on a computer) when you were instructed not to respond." (NCT04178993)

Delay Discounting for Methamphetamine

"Subjects will complete a delay discounting task in 4 sessions following 4 days of medication maintenance. Subjects are presented a series of hypothetical choices between a smaller amount of methamphetamine offered now or a larger amount of methamphetamine offered a later times in the future (e.g., 4 hours, a day, 3 weeks). The discounting rate, 'k', is calculated and log10-transformed. Greater values of log-transformed 'k' correspond with greater rates of discounting (i.e., preference for smaller reinforcer provided now rather than larger, delayed reinforcers [e.g., smaller amount of methamphetamine given now as opposed to a larger amount given later]). The units for discounting rates are theoretical and not linked to a physical dimension (e.g., number of button presses) and the range is theoretically not bound (i.e., negative infinity to positive infinity)."

Lane Position Deviation

The reported lane position deviation indicates the position of the car relative to the center line in feet in the driver simulator. A deviation of 0 indicates no deviation from the center line (the car is positioned farthest from the road edge). Negative numbers indicate deviations to the right of the center line with the car positioned within the lane closer to the road edge. Positive numbers indicate deviations to the left of the center line with the car positioned in the lane of oncoming traffic closer to the road edge (NCT00515294)

Psycho-motor Vigilance Test (PVT)

Participants completed 10 test trials to assess their psycho-motor response using a hand held box that randomly starts a scroll of numbers in milliseconds and as soon as it starts to scroll the participant needs to press a button to stop the scrolling. The mean and standard deviations for the 10 tests were calculated as a single outcome score for each study arm. Response times were measured in milliseconds. The lower the number of milliseconds the faster the response to the random stimuli. (NCT00515294)

"Overall Proportion Saying Yes to Real Prism Glasses"

"At the end of each crossover period, participants were asked a yes/no question: If the study were to end today, would you want to continue with these prism glasses (i.e. the prism glasses worn in that period)? The primary outcome was the overall difference, across the two periods of the crossover, between the proportion of participants saying yes to real prism glasses and the proportion saying yes to sham prism glasses."

Mobility Change Score (All Participants Who Completed Crossover)

Perceived difficulties with mobility were quantified using a 5-point rating scale (no difficulty to extreme difficulty) for 7 situations (items) relevant to people with hemianopia, including at home, in stores, outdoors, in unfamiliar areas, in familiar areas, in crowded areas, and noticing objects off to the side when walking. The questionnaire was administered at baseline (without prisms) and after each period of the crossover. Interval scale measures of perceived difficulty with overall mobility for each participant were estimated using Rasch analysis of the responses to all seven items (Winsteps software, version 3.70.0.226). Rasch measures were expressed as logits (log odds ratios). Mobility change scores for real and sham prisms were defined as the difference in perceived difficulty relative to baseline (in logits).

Perceived difficulties with mobility were quantified using a 5-point rating scale (no difficulty to extreme difficulty) for 7 situations (items) relevant to people with hemianopia, including at home, in stores, outdoors, in unfamiliar areas, in familiar areas, in crowded areas, and noticing objects off to the side when walking. The questionnaire was administered at baseline (without prisms) and after each period of the crossover. Interval scale measures of perceived difficulty with overall mobility for each participant were estimated using Rasch analysis of the responses to all seven items (Winsteps software, version 3.70.0.226). Rasch measures were expressed as logits (log odds ratios). Mobility change scores for real and sham prisms were defined as the difference in perceived difficulty relative to baseline (in logits).

Photostress Recovery Time

Photostress Recovery Time is the time necessary to recover function (e.g., contrast discrimination) following exposure to a bright glare source. The subject fixated on an image (black and white grating) and underwent photostress (glare) for 5 seconds. Only 1 eye (study eye) was assessed. (NCT01938989)

Change in Braking Reaction Time From No-glare to Glare (ACRYSOF® IQ IOL + Placebo Filter; Clear IOL + BLF)

Braking reaction time (time to brake, in seconds) was assessed using a driving simulator in no-glare and glare conditions. The subject was presented with a driving scenario during which an obstruction (car pulling over from either side of the road in a random fashion) was presented. Subjects braked in an attempt to avoid colliding with the obstruction, and the braking reaction time was recorded. The experiment was repeated with a glare source present. Both assessments (no-glare and glare) occurred on the same day. Change in braking reaction time was calculated as glare minus no-glare. (NCT02219997)

"Subjective Effects as Assessed by Score on Feel Drug, Feel High, Like Drug, and Want More Subscales of the Drug Effects Questionnaire"

"The Drug Effects Questionnaire (DEQ) is a visual analog scale questionnaire that assesses the extent to which subjects experience four subjective states: Feel Drug, Feel High, Like Drug, and Want More. The Feel Drug, Feel High, Like Drug, and Want More subscales are reported. All subscales are scored on a visual analogue scale (scroll bar on computer screen) ranging from 0-100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome."

Effect of Entacapone on Methamphetamine-induced Mood

Profile of Mood States is a 65 item questionnaire using a Likert rating scale to assess transient, distinct moods. The questionnaire contains 65 words/statements that describe feelings people have. The test requires you to indicate for each word or statement how you have been feeling in the past week including today. A Total Mood Disturbance score is calculated by adding scores for Tension, Depression, Anger, Fatigue and Confusion and then subtracting the Vigour score. The Total Mood Disturbance scale ranges from -32 to 200 with lower scores indicative of people with more stable mood profiles. (NCT02058966)
Timeframe: Measurements acquired before drug ingestion (baseline) then hourly for 4 hours. The peak interaction effect of entacapone and methamphetamine occurs 1 hour after ingestion, therefore the reported values are from this timepoint.

Cognitive Function

Two computer tests were administered to measure how each medication intervention effects cognitive functioning. The tests administered included the Rapid Visual Information Processing Task (RVIPT), a 6 minute test of sustained attention in which participants are requested to detect target sequences of digits and the Digit Symbol Substitution Task (DSST), a 2 minute test of psychomotor speed and sustained attention consisting of digit-symbol pairs followed by a list of digits where the subject identifies the symbol that corresponds to each digit as fast as possible. The number of correct responses within the allowed time is measured. Higher scores on both tasks indicate better performance. (NCT02058966)

Effect of Entacapone on Subjective Effects of Methamphetamine

The subjective effects of the study drug were evaluated with the Addiction Research Center Inventory (ARCI-49), a 49 item questionnaire consisting of true/false items. True items receive a score of 1 if answer is 'True', false items receive a score of 1 if answer is 'False'. No points are given when answer is opposite to scoring direction. There are 5 subscales: Morphine Benzedrine group scale to measure euphoria (range: 0-16 with higher numbers indicating more euphoria), A Lysergic Acid Diethylamide group scale to estimate dysphoria and agitation (range: 0-14 with higher scores indicating more dysphoria), a Pentobarbital Chlorpromazine Alcohol group scale to measure sedation (range: 0-15 with higher scores indicating more sedation), and a Benzedrine group scale and an Amphetamine Scale to assess stimulant effects (range: 0-13 and 0-11, respectively, with higher scores indicating higher stimulant effects) .

Exotropia Control Score at Distance, Continuous Change Between Baseline and 8 Weeks

Control of the exodeviation was measured at distance using the IXT Office Control Score, (Mohney, 2006) which ranges from 0 (phoria) to 5 (constant exotropia). Control levels 3-5 were assigned based on the duration of manifest exotropia during a 30-second period before any dissociation. If no exotropia was observed, control levels 0-2 were assigned based on the longest time to reestablishing fusion after 3 consecutive 10-second periods of dissociation. Control was measured at the beginning, middle, and end (3 tests) of a 20- to 40-minute office examination, and the mean was used. The change in distance control from baseline to 8 weeks will be calculated. A negative value indicates improvement. (NCT03998670)

Fusional Convergence - Continuous Break Point

As an exploratory analysis, the distribution of fusional convergence amplitude (break point, blur point, and recovery) at 8 weeks will be summarized for each treatment group. Fusional amplitudes are a measure of how well a participant can converge their eyes using fusional vergence. It is measured by increasing base-out prism to the point that the participant is no longer able to control the deviation. The total amount of fusion is the magnitude of the base-out prism the participant was able to overcome plus the magnitude of the deviation. A higher number of prism diopters for break point is better than a lower number. A lower number for recovery point is better than a higher number. (NCT03998670)
