OPEN-ACCESS ACADEMIC ARCHIVE • EST. 2017

Empirical Proceedings in Behavioral Medicine & Preventive Health

The European Health Psychology Research Consortium curates and disseminates open-access clinical monographs spanning occupational biomechanics, visual ergonomics, circadian chronobiology, oral-systemic inflammation, and preventive nutritional epidemiology.

"True preventive medicine does not wait for catastrophic end-organ failure to initiate therapy. By measuring and modifying the granular physiological stresses of daily life—the ciliary spasm of screen work, the vascular inflammation of subgingival dysbiosis, and the cellular insult of ultra-processed food matrices—we convert behavioral science into durable cardiovascular and neuro-cognitive longevity."

CLINICAL METHODOLOGY TOOL

Behavioral Intervention Effect-Size Calculator

Compute standardized mean difference (Cohen's d), small-sample bias-corrected Hedges' g, and Number Needed to Treat (NNT) from trial outcome means.

Load Trial Scenario Preset:

Intervention Mean (μ₁) Experimental group mean

Control Mean (μ₂) Control / baseline mean

Pooled SD (s_pooled) Root mean square SD

Control Event Rate (%) Baseline event rate (CER)

Sample Size N₁ Intervention cohort size

Sample Size N₂ Control cohort size

+1.27

Cohen's d

+1.26

Hedges' g

+0.93 to +1.60

95% Confidence Interval

2.3

Number Needed to Treat (NNT)

0.0 (Null) 0.2 (Small) 0.5 (Mod) 0.8+ (Large)

Large effect (|d| ≥ 0.80): Treating 2.3 participants achieves 1 additional favorable clinical outcome above baseline (CER = 30%).

CROSS-DISCIPLINARY META-SYNTHESIS

Pooled Effect Sizes Across Archive Proceedings

Summary DerSimonian-Laird random-effects meta-analysis quantifying the clinical magnitude of behavioral, ergonomic, and nutritional interventions across eight primary research tracks.

FIGURE: META-ANALYTIC FOREST PLOT

Consortium Meta-Synthesis: Multi-Component Behavioral & Preventive Interventions (k = 8 Trials)

Statistical Interpretation: Forest plot illustrates random-effects DerSimonian-Laird meta-analytic modeling. Blue squares designate individual trial effect metrics with area inversely proportional to standard error; horizontal whiskers denote 95% confidence intervals. The green diamond indicates the combined pooled summary vector and aggregate 95% CI boundaries.

Open-Access Repository Mandate

Founded in 2017 in Rotterdam, the European Health Psychology Research Consortium operates under the principle that clinical preventive science belongs in the public domain. All proceedings are freely accessible under Creative Commons CC BY 4.0 licensing with zero article processing charges or paywalls.

Rigorous Double-Blind Review

Every archived monograph undergoes structured double-blind evaluation by at least two independent methodological referees. Submissions require explicit statistical power calculations, raw data transparency, and pre-registered protocol validation to ensure reproducibility.

Translational Clinical Impact

We bridge academic behavioral psychology and bedside clinical practice. Our interactive calculators, standardized effect metrics, and evidence-graded protocol matrices equip practitioners with validated tools to optimize patient outcomes.
