The transferability of a Mediterranean diet (MedDiet) in non-Mediterranean populations is appealing. However, little is known about the perceived enablers or barriers toward adherence, particularly in Australia. This study aimed to investigate the perceived beliefs, barriers, and enablers toward adherence to a MedDiet in Australian adults. Barriers and enablers were assessed using a self-administered online questionnaire, which included questions aligned with the Theory of Planned Behaviour (TPB). The survey was completed by = 606 participants. Barriers and enablers toward adherence to MedDiet were grouped under the three core constructs of the TPB: attitudes (suitability, taste, restrictive, food waste); social norms (food culture); and perceived behavioural control (PBC) (motivation, affordability, time/effort, food access, knowledge, food outlets, natural conditions, cooking skills). PBC emerged as the most prominent construct influencing intention to follow a MedDiet. Perceived health benefits ( = 445; 76.5%) and improved diet quality ( = 224; 38.5%) were identified as major advantages. In contrast, dietary adherence ( = 147; 39.7%) was perceived as an important disadvantage. Future MedDiet interventions, in both research and clinical settings, should consider adopting strategies aimed at improving self-efficacy to reduce self-perceived barriers and facilitate dietary adherence.
地中海饮食（MedDiet）在非地中海人群中的可转移性很有吸引力。然而，人们对其在澳大利亚的可接受性的促进因素或障碍知之甚少。本研究旨在调查澳大利亚成年人对遵循地中海饮食的感知信念、障碍和促进因素。使用自我管理的在线问卷评估障碍和促进因素，该问卷包括与计划行为理论（TPB）一致的问题。该调查由 606 名参与者完成。遵循地中海饮食的障碍和促进因素被分为 TPB 的三个核心构念：态度（适宜性、口味、限制性、食物浪费）；社会规范（饮食文化）；以及感知行为控制（PBC）（动机、负担能力、时间/精力、食物获取、知识、食物来源、自然条件、烹饪技能）。PBC 是影响遵循地中海饮食意图的最突出的构念。感知健康益处（ = 445；76.5%）和改善饮食质量（ = 224；38.5%）被认为是主要优势。相比之下，饮食依从性（ = 147；39.7%）被认为是一个重要的劣势。未来的地中海饮食干预，无论是在研究还是临床环境中，都应考虑采用旨在提高自我效能的策略，以减少自我感知的障碍并促进饮食依从性。
