Counselors reported being the “heartbeat of the school” in supporting student wellness, yet needed better structural support. This work underscores counseling psychology practice in public education settings, illustrating counselors’ crucial (if challenged) role in addressing community trauma and student well-being in a public-sector context.

Social Psychology

Peer Influence to Reduce School Bullying (2016) – Elizabeth L. Paluck et al., Proceedings of the National Academy of Sciences. A field experiment in 56 schools assigned influential students to lead anti-conflict campaigns. Treated schools saw a ~30% drop in student conflict reports over one year

Developmental/Educational Psychology

Growth Mindset Intervention in U.S. High Schools (2019) – David S. Yeager et al., Nature. A nationally representative experiment with 12,000 students showed that a 50-minute growth-mindset exercise (teaching that intelligence can be developed) led to higher grades among lower-achieving teens and increased enrollment in advanced math the following year

pubmed.ncbi.nlm.nih.gov

Notably, schools with supportive peer norms saw the strongest effects. This study illustrates how educational psychology insights can be applied at scale in public schools to improve academic outcomes, especially for underserved students.

Community-Based Early Childhood Education in Indonesia (2017) – Sally Brinkman et al., Journal of Labor Economics. In a World Bank-supported trial across 310 villages, a package of low-cost, community-run preschool centers (with teacher training and parent engagement) produced sustained gains in children’s social, emotional, and cognitive development for those with 2–3 years of exposure

Disadvantaged children showed the greatest improvements. This research demonstrates developmental psychology principles applied in the public sector: government-sponsored early education programs can yield modest but meaningful developmental benefits in resource-limited settings.

Long-Term Impact of Social-Emotional Learning (SEL) Programs (2017) – Rebecca D. Taylor et al., Child Development. This meta-analysis followed up on 82 school-based SEL interventions (over 97,000 students). Months to years after program end, youth who received SEL curricula in primary or secondary school showed better social-emotional skills, positive attitudes, higher well-being, and even higher graduation rates, compared to controls

pubmed.ncbi.nlm.nih.gov

Benefits held across urban, rural, and diverse student groups. These findings affirm that educational psychology interventions (like SEL, often implemented district-wide or via nonprofit partnerships) can have lasting public-sector impact by promoting healthy development and life outcomes.

Behavioral Psychology

Text-Message “Nudges” to Boost Vaccination (2021) – Katherine L. Milkman et al., PNAS. A mega-study with over 600,000 participants tested various text reminders to encourage influenza vaccination. On average, reminder texts increased vaccination uptake by about 5% among patients due for a shot

The most effective messages prompted patients to plan a specific clinic visit nature.com

This large field experiment – led by behavioral scientists in collaboration with a public healthcare system – exemplifies how simple conditioning and prompt techniques can be applied at scale to improve public health outcomes (here, increasing immunizations).

Contingency Management for Substance Use Disorders (2017) – Nancy M. Petry et al., Psychology of Addictive Behaviors. Decades of research reviewed in this article show that contingency management (CM) – a behavioral approach offering tangible rewards for clean drug tests – dramatically improves treatment results in community clinics. In one national trial, patients receiving CM in addition to standard care achieved about 4.4 weeks of continuous abstinence vs. 2.6 weeks under standard care alone

pmc.ncbi.nlm.nih.gov

Despite initial skepticism, CM programs are now being adopted in public addiction clinics, illustrating applied behavior analysis techniques improving outcomes in real-world public healthcare settings.

Social Comparison Feedback for Resource Conservation (2018) – Opower energy reports, as summarized by J-PAL. Behavioral “nudges” are used by utilities and governments to encourage environmental conservation. For example, home energy reports comparing a household’s electricity use to neighbors’ use consistently lead to small reductions in energy and water consumption across diverse sites

povertyactionlab.org

Across 115 utility programs (8.6 million households), this intervention leveraging social norms yielded measurable savings at minimal cost

povertyactionlab.org

This demonstrates how behavioral psychology insights (like feedback and norm activation) are deployed by public-sector and nonprofit programs to influence citizen behavior for the public good – albeit as one piece of a larger policy puzzle in tackling climate change.

Psychiatry

Coordinated Specialty Care for First-Episode Psychosis (2015) – John M. Kane et al., American Journal of Psychiatry. The NIMH RAISE study compared a team-based early intervention program (NAVIGATE) to typical community care for young patients with first-episode schizophrenia. After 2 years, those in the NAVIGATE program stayed in treatment longer and had greater improvements in symptoms, quality of life, and work or school involvement than those in standard care

This underscores how psychiatry-led multidisciplinary teams in the public sector (often implemented in community mental health centers) can significantly improve recovery outcomes for serious mental illness by providing comprehensive, proactive care.

“Housing First” for Homeless Individuals with Mental Illness (2019) – Vicky Stergiopoulos et al., The Lancet Psychiatry. This study extended a large Canadian trial of Housing First (immediate housing plus mental health support, delivered by ACT-style teams). Over 6 years, participants who received rent supplements and psychiatric support had markedly higher housing stability (spending 86% of time in stable housing) than those in usual shelters, with the biggest gains for those with the highest support needs

pubmed.ncbi.nlm.nih.gov

Certain health outcomes also improved

These findings illustrate psychiatry in public service: addressing homelessness via integrated housing and mental-health programs (often run by government or nonprofits) yields lasting benefits for this at-risk population.

Telepsychiatry Collaborative Care for Rural PTSD (2015) – John C. Fortney et al., JAMA Psychiatry. This randomized trial deployed a telemedicine-based collaborative care model to reach U.S. rural veterans with PTSD. A specialized remote team (psychiatrist, psychologist, nurse) worked with local clinics to provide therapy and medication management via video/phone. The result: veterans in the telepsychiatry program were far more likely to engage in evidence-based PTSD therapy (55% vs 12% in usual care) and showed significantly greater symptom reduction

This study highlights how psychiatric expertise, when delivered through innovative telehealth programs in the public sector (the VA system), can overcome geographic barriers and improve mental health outcomes in underserved communities.

Each of these peer-reviewed articles exemplifies psychology applied beyond the traditional clinic – whether through community-based programs, schools, public health systems, or social services. Across subfields, the research demonstrates that psychological training and interventions can be tailored to serve public needs: improving disaster response, expanding mental health access via lay providers, informing education and youth programs, influencing healthy behaviors, and innovating service delivery for vulnerable populations. These studies collectively show the value of psychological insights in nonprofit and public-sector initiatives aimed at enhancing community well-being
