NexQuest Natural Frequency Technology (NFT ), intended to enhance biological function using naturally occurring frequencies, may be a nonpharmacological intervention to improve stress and health. The study purpose was to determine the effectiveness of NFT for improving stress, sleep quality, mood, and cognition in adults.
Using a double-blind placebo-controlled crossover design, participants with high perceived stress (N = 42, M age = 43.8) were assessed at baseline (BL) and assigned to either the Placebo Watch (PW) or Wellness Watch (WW) condition for 2 weeks, and then 2 weeks in the alternate condition. Participants completed the following self-report surveys of Perceived Stress Scale, Pittsburgh Sleep Quality Index, Insomnia Severity Index, Food Craving Questionnaire, and Profile of Mood States, as well as the CNS Vital Signs neurocognitive test at BL and following each condition.
The WW condition had significant improvements in sleep duration and Complex Attention compared to the PW group. Compared to BL, both conditions had significant improvements for perceived stress, food cravings, mood, sleep quality, and several cognitive tests, p's < .05.
Despite the placebo effect, NFT may be a natural alterative for improving stress and health. Research is needed examining the efficacy of NFT in a variety of populations and environments.
NexQuest 自然频率技术（NFT）旨在利用自然发生的频率来增强生物功能，它可能是一种非药物干预手段，可以改善压力和健康。本研究的目的是确定 NFT 对改善成年人压力、睡眠质量、情绪和认知的有效性。
采用双盲安慰剂对照交叉设计，高感知压力的参与者（N=42，M 年龄=43.8）在基线（BL）进行评估，并分配到安慰剂观察（PW）或健康观察（WW）条件下 2 周，然后在交替条件下 2 周。参与者在 BL 和每个条件后完成以下自我报告调查：感知压力量表、匹兹堡睡眠质量指数、失眠严重程度指数、食物渴望问卷和心境状态问卷，以及 CNS 生命体征神经认知测试。
与 PW 组相比，WW 条件在睡眠持续时间和复杂注意力方面有显著改善。与 BL 相比，两种条件在感知压力、食物渴望、情绪、睡眠质量和几项认知测试方面都有显著改善，p 值均<.05。
尽管存在安慰剂效应，但 NFT 可能是改善压力和健康的自然替代方法。需要研究 NFT 在各种人群和环境中的疗效。
