Mindfulness Lowers Anxiety & Boosts Energy - Inside the 1,492-Person MAAS Study

A large study set out to answer a simple question - Does being more mindful actually improve mental, emotional, and physical health? The results are striking—and they might just change how you think about attention.

About one in three U.S. adults will experience an anxiety disorder at some point in their lives. NIMH Globally, around 4 in 10 adults report high stress on a given day. Gallup.com

That’s why a study published in Journal of Personality and Social Psychology, titled “The Benefits of Being Present: Mindfulness and Its Role in Psychological Well-Being”, becomes so important. It asks a very simple yet fundamental question:

Does being mindful actually improve mental and emotional health?

Note that the question is only about being “mindful”—not meditation, not breathing exercises, not a full body scan. Those practices can help, but this study is specifically about just being “mindful”. Brown and Ryan define mindfulness as “receptive, present-moment attention/awareness,” or simply, being present in the moment.

They explored whether mindfulness contributes to better emotional health, self-regulation, and overall well-being. Rather than asking people if they “felt mindful”—they created a robust psychological scale (MAAS) to measure how mindful people actually were in their everyday lives.

The Study

The study used a multi-part approach. First, they built a tool called the Mindful Attention Awareness Scale (MAAS). It’s a 15-item questionnaire that captures how often someone is attentive and present in daily life. They tested whether people found themselves running on autopilot, missing what’s happening around them.

They tested this with 1,492 individuals—including college students, community adults, and even Zen practitioners—ranging in age from 18 to 77.

To make it even more rigorous, they used experience-sampling methods (think mini check-ins throughout the day) and even ran a clinical trial with cancer patients undergoing mindfulness-based stress reduction.

And they found something remarkable.

Findings

Let me summarise their findings in 4 key points:

1. More mindfulness = better mental health.
People who scored higher on the MAAS consistently reported lower levels of anxiety, depression, and neuroticism (tendency to experience negative emotions such as anxiety, anger, and sadness, and to react strongly to stressful situations). They also had higher levels of optimism, vitality, and life satisfaction.

2. Mindful people weren’t just “reflective”—they were present.
Rather than ruminating or overthinking, mindful individuals reported less self-consciousness and fewer intrusive thoughts. Staying present appeared to support greater emotional stability and resilience. Think pop-up blocker for your runaway thoughts.

3. Mindfulness predicted physical health too.
Those who were more mindful reported fewer physical symptoms, less somatization (where mental distress is experienced as bodily discomfort), and even fewer medical visits.

4. Training matters.
Zen practitioners—especially those with longer meditation experience—scored higher on mindfulness. Interestingly what mattered most wasn’t how much they meditated—it was how much they brought that awareness into daily life. Just being present is all it takes.

In short, higher present-moment attention and awareness (as measured by the MAAS) is consistently associated with better psychological and physical well-being. This holds across diverse samples—even after accounting for personality traits and affective tendencies.

Why It Matters

In fast-paced work, mindless autopilot fuels errors and drain mood.

Higher mindfulness—simply paying attention to what you’re doing:

  • Aligns actions with goals
  • Improves emotion regulation,
  • Reduces depression and anxiety
  • Improves energy

Which translates to fewer rework loops, clearer decisions, and steadier leadership.

What It Means for You

Here are a few low-effort ways to apply this research in everyday life:

  • Notice when you’re on autopilot. Even catching yourself zoning out is a moment of mindfulness.
  • Try a 2-minute check-in. Pause during the day and ask: “What am I doing? How do I feel?”
  • Don’t overthink mindfulness. It’s not about emptying your mind. It’s about showing up for the moment you’re in, being present.
  • Focus on one task. Multitasking is the enemy of mindful attention—and often, of effectiveness.
  • Bring mindfulness into routine activities. Washing dishes, walking, or even drinking tea can be anchors for present-moment awareness.

Practitioner Tip: How can you try this?

  • 60-second “Attn-Reset” (3×/day): Pause before key tasks (email block, meeting, coding). Name three sensory cues (what you see/hear/feel), then state your single next action aloud. Tracks to MAAS’s focus on present actions. Do this for 2 weeks.

  • One-tab Work Sprints: 25-minute single-task intervals; close extra tabs/apps; jot distractions on a pad (address later). Reduces “automatic pilot” captured by MAAS items.

  • Mindful Transitions: Between meetings, take three breaths, scan for tension (jaw/shoulders), and decide the one outcome you want from the next block.

  • Weekly Autopilot Audit: Pick two MAAS items (e.g., “I rush through activities…”). For 7 days, tally occurrences; choose one ritual to slow down (e.g., mindful first sip of coffee, first minute of a call for silence + agenda).

Technical Summary

TL;DR

  • Study: Multi-study paper introducing the Mindful Attention Awareness Scale (MAAS) and testing links between mindfulness and well-being in college students, adults, meditators, and a clinical sample.
  • Finding: Higher mindfulness correlated with lower depression/anxiety, higher positive affect, life satisfaction, vitality, and basic psychological needs, with evidence holding after controlling for major personality and affective factors (see Table 4 and Table 5).
  • Why does it matter: Mindfulness—as simple present-moment awareness—relates to better day-to-day regulation and mood; practitioners and leaders can use brief, repeatable practices to improve focus and emotional balance.

This paper asks whether a basic skill—being present—is tied to better well-being. Brown & Ryan develop the MAAS and test if trait/state mindfulness predicts mood, self-regulation, and stress outcomes across multiple designs.

The authors define mindfulness as receptive, present-moment attention/awareness and distinguish it from reflective self-analysis.

They construct the MAAS via item reduction and factor analyses, yielding a 15-item, single-factor scale with solid internal consistency and test–retest stability.

Across convergent/discriminant tests (e.g., emotional intelligence, openness, self-consciousness, rumination), mindfulness shows the expected pattern:

  • Positively related to
    • clarity of emotions
    • needs fulfillment
  • Negatively to
    • rumination
    • social anxiety
    • neuroticism.

Critically, mindfulness correlates with well-being—lower depression/anxiety and higher positive affect, vitality, and life satisfaction—and these associations remain significant after adjusting for private self-consciousness, rumination, emotional intelligence, neuroticism, extraversion, and social desirability.

Mindfulness differentiates meditators from matched community members (medium–large effects). The program also includes experience-sampling and a clinical intervention (cancer patients) where increases in mindfulness tracked decreases in mood disturbance and stress.

Methods Overview

  • Scale development: 184 → 15 items via expert review, piloting, and EFA/CFA; single-factor solution; 6-point Likert (higher = more mindfulness). Reliability α≈.82–.87; ICC over 4 weeks =.81.
  • Correlational batteries (Study 1): Six samples (students + adults) completed MAAS and personality/affect/well-being instruments; incremental validity tested with partial correlations (Table 5).
  • Known-groups (Study 2): Zen practitioners vs matched community adults (age/gender); mindfulness higher in meditators; effects stronger among those actively practicing.
  • Other designs summarized in the paper: Experience sampling (trait & state mindfulness predicting self-regulation, positive emotion) and clinical intervention in cancer patients (mindfulness increases aligned with decreases in mood disturbance/stress). Details concise in abstract.

Key Findings

  • Mindfulness is measurable and stable: MAAS is single-factor, reliable (α ≈ .82–.87), and stable over 4 weeks (ICC =.81). CFA showed satisfactory fit in students and adults.

  • Mindfulness relates to better mental health and functioning: Higher MAAS linked to less neuroticism, depression, anxiety, negative affect, and more positive affect, vitality, life satisfaction, self-esteem, optimism, and need satisfaction (Table 4).

  • Effects are not just personality spillover: Associations remain significant after adjusting for private self-consciousness, rumination, emotional intelligence, neuroticism, extraversion, and social desirability (Table 5).

  • Mindfulness differentiates meditators: Zen practitioners scored higher than matched community adults; effect sizes medium to large; stronger among currently practicing meditators.

  • Clinical & momentary evidence (brief): Increases in mindfulness in cancer patients related to declines in mood disturbance and stress; state/trait mindfulness predicted self-regulated behavior and positive emotion in experience sampling.

Selected numeric results (bold = p < .05):

  • Reliability: α=.82–.87 (various samples); ICC=.81 over 4 weeks (ns change in means).

  • CFA fit (students): χ²(90)=189.57; GFI=.92; CFI=.91; RMSEA=.058 (all loadings p<.001). Adults: χ²(90)=179.14; GFI=.91; CFI=.92; RMSEA=.065 (all p<.001).

  • Correlations with well-being (Table 4): Neuroticism r=−.56; Depression (BDI) r=−.41 to −.42; Anxiety (STAI) r=−.40; Positive Affect (PANAS) r=.30–.39; Negative Affect r=−.39 to −.43; Life Satisfaction r=.26–.37; Vitality r=.35–.46 (all p<.0001–.01 across samples).

  • Incremental validity (Table 5): After controlling for covariates, MAAS still related to BDI (partial r≈−.29 to −.44), Positive Affect (partial r≈.25–.31), Self-Esteem (partial r≈.32–.42) (all p ≤ .05).

  • Known-groups (Zen vs matched controls): t(98)=2.45, p<.05, d=.50; among active meditators: t(82)=3.09, p<.005, d=.68; dosage: years of practice r=.36, p<.05.

Limitations Stated by Authors

  • Experience-sampling and clinical details are summarized briefly in this article segment; full protocols not provided here.

  • Social desirability shows modest correlation in some samples (Marlowe–Crowne), though effects persisted after control.

  • Group difference results could reflect self-selection into meditation; authors acknowledge this possibility.

My Notes

  • Measurement scope: MAAS targets attention/awareness, not acceptance or non-judgment; other facets of mindfulness aren’t captured—this may underestimate full construct effects.

  • Causality: Predominantly cross-sectional; associations are not causal. Clinical and ESM hints help, but RCTs are needed.

  • Generalizability: Many student samples; adult data help, but broader cultural/occupational diversity is limited.

What we can conclude confidently:
Higher present-moment attention/awareness (MAAS) is consistently associated with better psychological well-being across multiple samples, even after accounting for personality and affective tendencies. (Tables 4–5).

Glossary

  • Mindfulness (MAAS): Being attentive/aware of the present—what you’re doing, feeling, sensing—without getting lost in rumination or future worries.
  • MAAS: A 15-item questionnaire measuring frequency of present-moment attention/awareness; higher scores mean more mindfulness. Single-factor, reliable.
  • Incremental validity: Showing the MAAS predicts outcomes even after controlling for other traits (e.g., neuroticism, rumination).
  • Known-groups validity: A measure’s ability to distinguish groups expected to differ (e.g., meditators vs non-meditators).
