This dataset provides information regarding a dataset of individuals exploring concepts of infidelity as they relate to personality traits, demographics, and concepts of personally socially appropriate behavior when in a closed relationship.

Within socially monogamous breeding systems, levels of extra-pair paternity can vary not only between species, populations and individuals, but also across time. Uncovering how different extrinsic conditions (ecological, demographic and social) influence this behavior will help shed light on the factors driving its evolution. Here, we simultaneously address multiple socio-ecological conditions potentially influencing female infidelity in a natural population of the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis. Our contained study population has been monitored for over 25 years, enabling us to capture variation in socio-ecological conditions between individuals and across time and to accurately assign parentage. We test hypotheses predicting the influence of territory quality, breeding density and synchrony, group size and composition (number and sex of subordinates), and inbreeding avoidance on female infidelity. We find that a larger group size promotes the likelihood of extra-pair paternity in offspring from both dominant and subordinate females, but this paternity is almost always gained by dominant males from outside the group (not by subordinate males within the group). Higher relatedness between a mother and the dominant male in her group also results in more extra-pair paternity — but only for subordinate females — and this does not prevent inbreeding occurring in this population. Our findings highlight the role of social conditions favoring infidelity and contribute towards understanding the evolution of this enigmatic behavior.

The data presented here contains information on cheating behaviour from experiments and general self-reported attitudes related to honesty-related social norms and trust, together with individual level demographic variables. Our sample includes 493 university students in five countries, namely Germany, Vietnam, Taiwan, China, and Japan.

The online couples therapy market is experiencing robust growth, fueled by increasing accessibility, affordability, and the rising prevalence of relationship issues. The convenience of virtual sessions eliminates geographical barriers and scheduling conflicts, attracting a broader demographic than traditional in-person therapy. While precise market sizing is unavailable, a reasonable estimation, considering the growth of the broader telehealth market and the increasing adoption of online therapy platforms, would place the 2025 market size in the range of $500 million to $750 million USD. A Compound Annual Growth Rate (CAGR) of 15-20% over the forecast period (2025-2033) appears feasible given current market trends and increasing consumer awareness of mental health resources. Key drivers include the increasing prevalence of relationship problems, the stigma reduction surrounding mental health, and technological advancements improving virtual therapy experiences. Trends indicate a move towards specialized platforms focusing on specific relationship issues (e.g., infidelity, communication difficulties), integration of technological advancements (AI-powered tools, virtual reality), and greater emphasis on preventative care and relationship coaching. However, restraints remain, including concerns about data privacy, the need for reliable internet access, and the difficulty in replicating the intimacy of in-person therapy. The market is segmented by therapy type (cognitive behavioral therapy, Gottman Method, etc.), platform features (individual vs. couples sessions, video vs. text), and demographics (age, income, location). Competition is intense, with established players like BetterHelp and Talkspace alongside niche providers catering to specific relationship dynamics or demographics. The future of online couples therapy hinges on addressing existing limitations. Improved security protocols and wider internet access are crucial for expanding reach. Further integration of technology, such as AI-driven chatbots for preliminary assessment and personalized support, can enhance the therapeutic process and improve efficiency. Greater emphasis on clinician training in online therapy modalities and stricter licensing regulations will boost consumer confidence and ensure quality of care. A focus on research and evidence-based practices will further solidify the efficacy and legitimacy of online couples therapy. Continued market growth will be propelled by increasing awareness campaigns, improved affordability and insurance coverage, and the ongoing evolution of technology to cater to the unique needs of couples seeking support.
