Abstract

Purpose

Adolescents need at least 60 min of physical activity (PA) every day. Yet, the number of minutes of daily PA steadily decreases from childhood through adolescence. This occurs despite evidence that high levels of PA and limited minutes of sedentary behavior (SB) decrease the incidence of heart disease, type 2 diabetes mellitus, obesity, and cancer. Motivational interviewing (MI) is a behavioral counseling technique that focuses on behavior change areas, such as diet and PA. This research aimed to evaluate a brief nurse-led virtual MI (vMI) intervention to guide youth toward increased PA compared to an attention control group.

Design and Methods

Participants completed the Behavioral Regulation in Exercise Questionnaire (BREQ-2) and wore an ActiGraph GT3X+ accelerometer on their dominant wrist for 8 days to operationalize SB and PA. Participants in the treatment group rec an individual vMI session, while attention-control group participants received an individual education session. All participants received follow-up calls from the researcher or assistant at Weeks 4 and 8. During the calls, those in the treatment group received follow-up MI, while the control group asked follow-up questions about information received during the education session. At 12 weeks, all participants repeated the BREQ-2 survey and wore the accelerometer again for 7 days.

Results

The total number of participants was 19. At post-intervention, the treatment group had a significant decline in the frequency of prolonged SB > 60 min (p = .001) and a nonsignificant increase in the average length of moderate-to-vigorous PA bouts >10 min (p = .058). The treatment group had significant increases in two levels of autonomous motivation—identified (p < .001) and intrinsic (p = .003). The overall autonomous motivation score for the BREQ-2 significantly increased in the treatment group (p < .001).

Practice Implications

The study revealed promise for vMI to positively impact PA among adolescents. However, for a novice in performing MI, a nurse-led MI session elicited change talk in participants toward individualized changes to improve health behaviors.

提高青少年体育锻炼的自主积极性

目的青少年每天至少需要 60 分钟的体育活动（PA）。然而，从童年到青春期，每天体育锻炼的分钟数在稳步减少。尽管有证据表明，高水平的体育锻炼和有限分钟的久坐行为（SB）可降低心脏病、2 型糖尿病、肥胖症和癌症的发病率，但这种情况还是出现了。动机访谈（MI）是一种行为咨询技术，主要针对饮食和 PA 等行为改变领域。本研究旨在评估一种由护士主导的简短虚拟动机访谈（vMI）干预方法，与注意力对照组相比，该方法可引导青少年增加体育锻炼。设计与方法参与者填写运动行为调节问卷（BREQ-2），并在主要手腕上佩戴 ActiGraph GT3X+ 加速计 8 天，以测定 SB 和 PA。治疗组的参与者接受了一次单独的 vMI 培训，而注意力控制组的参与者则接受了一次单独的教育培训。所有参与者在第 4 周和第 8 周都会接到研究人员或助理的后续电话。在电话中，治疗组的参与者接受了后续管理信息系统，而对照组的参与者则就教育课程中获得的信息提出了后续问题。在第 12 周，所有参与者都重复了 BREQ-2 调查，并再次佩戴加速度计 7 天。结果参与者总数为 19 人。在干预后，治疗组的长时间SB >60分钟的频率显著下降（p = .001），中度到剧烈运动的平均时长增加了10分钟（p = .058）。治疗组的两个自主动机水平--认同（p = .001）和内在（p = .003）都有明显提高。治疗组的 BREQ-2 自主动机总分也有明显提高（p <.001）。实践启示研究表明，vMI 有望对青少年的体育锻炼产生积极影响。然而，对于一名实施多元智能的新手来说，由护士主导的多元智能课程会引起参与者的改变言论，从而进行个性化的改变以改善健康行为。

期刊介绍： Linking science and practice by publishing evidence-based information on pediatric nursing and answering the question, ''How might this information affect nursing practice?'' The Journal for Specialists in Pediatric Nursing (JSPN) is the international evidence-based practice journal for nurses who specialize in the care of children and families. JSPN bridges the gap between research and practice by publishing peer-reviewed reliable, clinically relevant, and readily applicable evidence. The journal integrates the best evidence with pediatric nurses'' passion for achieving the best outcomes. The journal values interdisciplinary perspectives and publishes a wide variety of peer-reviewed papers on clinically relevant topics.
