Neurocognitive Enhancement Therapy, commonly shortened to NET, is a cognitive remediation program developed in the late 1990s and 2000s by Morris Bell and colleagues at the Yale School of Medicine and the VA Connecticut Healthcare System. It is one of the more carefully studied CRT variants and is distinctive for one specific design choice: NET is built to be delivered alongside paid work therapy. The cognitive training and the work happen in the same week, in the same program, supporting the same goal.
NET combines structured computer-based cognitive exercises, group strategy sessions, and concurrent supervised paid work to improve both cognitive functioning and actual job performance in people with schizophrenia.
The original problem NET was built to solve
By the late 1990s, vocational rehabilitation programs for schizophrenia had a recognised ceiling: even highly motivated participants in supported employment programs often plateaued in their job performance and tenure, and cognitive symptoms were the most-cited reason. Bell and colleagues hypothesised that the missing ingredient was direct, sustained cognitive training delivered alongside, not before, the work itself. NET was the resulting intervention.
What NET looks like in practice
A typical NET program runs for about six months. Each week includes:
- Computer-based cognitive training — usually three to five hours per week of adaptive exercises in attention, memory, and executive function. Programs such as PSSCogReHab and BrainHQ have been used.
- A weekly social cognitive group — typically 60 to 90 minutes, focused on translating cognitive gains into the social and problem-solving demands of work.
- Paid work therapy — typically 10 to 20 hours per week of supervised work in a real setting (hospital cafeteria, grounds, library, clerical office), at minimum wage or above.
The same therapist or coach often visits the work site, observes the participant in action, and brings real workplace examples into the cognitive training and group.
The signature evidence
The pivotal NET trials, published by Bell, Wexler, and colleagues over the 2000s and 2010s, found:
- Participants who received NET plus work therapy showed significant gains on measures of attention, working memory, and executive function compared with work therapy alone.
- The NET group worked more hours during the program and continued to work more hours and earn more after the program ended.
- Gains in cognition and work outcomes persisted at one-year follow-up.
- Effects were larger for participants who were lower-functioning at baseline — suggesting the combined cognition-plus-work intervention was particularly useful for those with the most need.
These trials are part of the wider body of evidence (summarised in Cochrane reviews of cognitive remediation) showing that CRT effects on real-world function depend on coupling with concurrent rehabilitation.
How NET differs from other CRT models
Versus NEAR
NEAR is delivered in clinical group settings with bridging to general life goals; NET is built specifically around concurrent paid work. Both are evidence-based; they target slightly different points in recovery.
Versus CET
Cognitive Enhancement Therapy emphasises social cognition and group-based skill development with longer treatment durations (often 18 months); NET is shorter and tighter around vocational outcomes.
Versus CRT-Wykes
CRT-Wykes is a paper-and-pencil therapist-delivered protocol focused on executive function, often delivered without integrated work. NET requires the work component.
Why the work component matters
Cognitive training improves test scores reliably across CRT models. The harder problem is transferring those gains to the messy demands of real life — particularly work, where the cognitive challenges (remembering a multi-step task, switching between customers, maintaining attention through a shift) are the actual barriers to staying employed. By training cognition and working at the same time, NET creates many opportunities each week for the trained skills to be applied in the place that matters. The transfer is built into the design rather than hoped for at the end.
Who NET fits
NET fits people who:
- Have a diagnosis of schizophrenia or schizoaffective disorder.
- Want to work or return to work.
- Can commit to several months of intensive scheduled programming.
- Have access to a program that offers integrated work therapy — historically most often a VA hospital, an academic medical centre, or a state psychiatric facility with a vocational program.
Who NET does not fit as well
NET is less suited to people in active acute psychosis, people who cannot commit to the schedule, and people whose primary goal is permanent competitive employment in a specific outside job — for whom IPS may be a more direct path. NET sits well as an intermediate stage for people who need to build cognitive capacity and a recent work history before pursuing competitive jobs in the open market.
How NET-style programs are organised today
The original NET trials were largely conducted at VA Connecticut and a small number of academic centres. Today, the broader principle — pair cognitive remediation with concurrent rehabilitation — has been incorporated into many Coordinated Specialty Care programs for first-episode psychosis, into VA programs serving veterans with serious mental illness, and into a growing number of community mental-health agencies. Few programs use the NET name directly, but the underlying combined model is increasingly common.
Practical access
If you are interested in NET-style intervention, ask:
- Whether your community mental-health agency offers cognitive remediation alongside supported employment or work therapy.
- Whether a nearby academic medical centre has a research program that includes CRT plus vocational rehabilitation.
- If you are a veteran, whether your VA has a Compensated Work Therapy or Therapeutic and Supported Employment Services (TSES) program — many of these incorporate cognitive remediation components.
- Whether your local Coordinated Specialty Care program for first-episode psychosis includes computerised cognitive training as part of its service package.
Like other forms of cognitive remediation, NET works best when symptoms, sleep, and medication are stable. If symptoms are acute, work with your treatment team on stabilisation first; cognitive remediation will deliver more value when the brain has the bandwidth to use it.
The contribution of NET to the field
NET demonstrated, more clearly than any preceding intervention, that the relationship between cognitive remediation and vocational rehabilitation is multiplicative rather than additive. Computer training alone produces score improvements; work therapy alone produces work hours; the combination produces both, and produces real-world gains that hold past the end of the program. Many of today's better cognitive remediation programs — including those embedded in NIMH-funded coordinated specialty care for first-episode psychosis — are direct intellectual descendants of NET. The principle is now mainstream: train the cognition, but train it in service of something the person actually wants to do.
