Clinical Trial Summary

Determine if an intervention consisting of future-thinking improves different facets of memory/executive function and/or decision-making.

Description:

The aim of this study is to determine if a cognitive intervention is an efficacious method for improving medication adherence in adults with prediabetes or type 2 diabetes. Participants in this study will complete assessment sessions, as well as intervention sessions over a 15 week period. During this time, medication adherence will be monitored using a MEMS cap. The investigators hypothesize that, following the cognitive intervention, there will be improvements in participants' medication adherence, as well as in facets of memory.

Eligibility

Inclusion Criteria:

Adults over the age of 18 with prediabetes or Type 2 Diabetes currently prescribed at least one oral medication for blood glucose regulation, or for related comorbidities e.g., hypertension, hyperlipidemia, and are relatively non-adherent to taking them (< 80% of prescribed doses taken), but are motivated and/or have the intent to better comply with their medication regimen, will be studied. Prediabetes and Type 2 Diabetes: Participants must have a diagnosis of prediabetes or Type 2 Diabetes within the last 2 years or meet criteria for prediabetes or Type 2 Diabetes. The American Diabetes Association guidelines (Group, 2003) defines prediabetes and Type 2 Diabetes as Fasting Plasma Glucose (FPG) 100mg/dl or greater, 2h glucose 140mg/dl or greater after Oral Glucose Tolerance Test (OGTT), or hemoglobin A1c (HbA1c) of approximately 5.4% or greater. Exclusion Criteria: Pregnancy: Women who are pregnant or lactating will be excluded from participation. Substance use, abuse, or dependence: Individuals that currently have problems with substance dependence, addiction, or problematic substance use that would limit participation (e.g., binge drinkers, alcoholics, daily stimulant/opiate users) will be excluded. Conditions that affect adherence: Participants should not have a condition that would limit participation which include medical conditions that would affect individuals' ability to use the computer for prolonged period of time; leave the individual unable to ambulate; unmanaged psychiatric disorder (e.g., depression, anxiety, attention deficit hyperactivity disorder, schizophrenia), cognitive impairment that would impact memory (e.g., symptomatic concussion), or an intellectual impairment that would impact study adherence. Additionally, participants should be able to attend to all intervention sessions. If a participant is not able to make most sessions (e.g. participant is out of town during most of the study for work or vacation travel), they may be excluded from the study Prior participation in similar studies: Individuals who have recently participated in a laboratory study using similar methods may also be excluded. Use of medication adherence aids: individuals who currently use aids to assist with medication adherence (e.g., pill organizers, reminder apps)may be excluded

Intervention

Behavioral:
• Episodic Future Thinking
This intervention involves participants engaging in episodic future thinking in order to improve their medication adherence and overall prospective thinking ability. This intervention will be introduced following a 6-week, 8-week or 10-week baseline period.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Medication Adherence	The investigators will measure medication adherence using a medication event monitoring system (MEMS) that measured the frequency and time the medication bottle is opened. Percent adherence was calculated [(Quantity of pills dispensed - remaining)/(quantity prescribed per day*days since last refill)] *100. Percent change was calculated from the last week of baseline to the first week of EFT and the last week of EFT	15 weeks
Primary	Prospective Memory	Prospective memory ability will be assessed using an event-based version of the virtual week task. This is a computer-based task in which participants are asked to completed different events at specified times in the style of a board game. For the event-based task, participants were asked to complete an extra mouse click when certain words appeared on the screen. Possible scores ranged from 0 - 8 with higher scores being indicative of better prospective memory.	15 weeks
Secondary	Delay Discounting	Delay Discounting will be assessed using an adjusting amount task where choices will be present between a larger, delayed amount of money ($100) and a smaller, immediate amount. The smaller, immediate amount will begin at $50 on the first trial and will be adjusted following each trial. Participants cues created during treatment will be displayed during the task. To calculate discount rates area under the curve will be used, in which normalized values of delayed reward and normalized values of delay are used, resulting in values from 0.0 (all immediate choices) and 1.0 (all delayed choices) result. Units are proportion of maximum delayed reward x proportion of maximum delay.	15 weeks
