Mapping the evidence base of positive psychology interventions: effectiveness, limitations, and future directions.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Positive psychology interventions (PPIs) have emerged as a scientifically grounded body of practice aimed at fostering wellbeing, resilience, and optimal human functioning. Over the past two decades, the empirical literature has expanded substantially, yet critical gaps remain regarding intervention fidelity, population specificity, moderating variables, and long-term efficacy. This systematic review aims to map the evidence base of PPIs by synthesizing findings from meta-analyses, randomized controlled trials (RCTs), and recent empirical studies; identifying effectiveness across diverse populations; delineating methodological limitations; and articulating future research priorities. Methods: A systematic search of PubMed, PsycINFO, Web of Science, and Scopus was conducted using Boolean search strategies. Studies published between 2000 and 2025 were included. PRISMA 2020 guidelines informed the review protocol. Sixty-three primary studies and 11 meta-analyses met inclusion criteria. Results: PPIs demonstrated consistently positive effects on subjective wellbeing (SWB), life satisfaction, and positive affect (mean Discussion: The evidence base for PPIs is substantive but uneven. Future research must address longitudinal effectiveness, cultural adaptation, personalized digital delivery, and integration with clinical practice.
