Web-Based Video-Coaching to Assist an Automated Computer-Tailored Physical Activity Intervention for Inactive Adults: A Randomized Controlled Trial

Abstract

BackgroundWeb-based physical activity interventions that apply computer tailoring have shown to improve engagement and behavioral outcomes but provide limited accountability and social support for participants. It is unknown how video calls with a behavioral expert in a Web-based intervention will be received and whether they improve the effectiveness of computer-tailored advice.ObjectiveThe purpose of this study was to determine the feasibility and effectiveness of brief video-based coaching in addition to fully automated computer-tailored advice in a Web-based physical activity intervention for inactive adults.MethodsParticipants were assigned to one of the three groups: (1) tailoring + video-coaching where participants received an 8-week computer-tailored Web-based physical activity intervention (“My Activity Coach”) including 4 10-minute coaching sessions with a behavioral expert using a Web-based video-calling program (eg, Skype; n=52); (2) tailoring-only where participants received the same intervention without the coaching sessions (n=54); and (3) a waitlist control group (n=45). Demographics were measured at baseline, intervention satisfaction at week 9, and physical activity at baseline, week 9, and 6 months by Web-based self-report surveys. Feasibility was analyzed by comparing intervention groups on retention, adherence, engagement, and satisfaction using t tests and chi-square tests. Effectiveness was assessed using linear mixed models to compare physical activity changes between groups.ResultsA total of 23 tailoring + video-coaching participants, 30 tailoring-only participants, and 30 control participants completed the postintervention survey (83/151, 55.0% retention). A low percentage of tailoring + video-coaching completers participated in the coaching calls (11/23, 48%). However, the majority of those who participated in the video calls were satisfied with them (5/8, 71%) and had improved intervention adherence (9/11, 82% completed 3 or 4 modules vs 18/42, 43%, P=.01) and engagement (110 minutes spent on the website vs 78 minutes, P=.02) compared with other participants. There were no overall retention, adherence, engagement, and satisfaction differences between tailoring + video-coaching and tailoring-only participants. At 9 weeks, physical activity increased from baseline to postintervention in all groups (tailoring + video-coaching: +150 minutes/week; tailoring only: +123 minutes/week; waitlist control: +34 minutes/week). The increase was significantly higher in the tailoring + video-coaching group compared with the control group (P=.01). No significant difference was found between intervention groups and no significant between-group differences were found for physical activity change at 6 months.ConclusionsOnly small improvements were observed when video-coaching was added to computer-tailored advice in a Web-based physical activity intervention. However, combined Web-based video-coaching and computer-tailored advice was effective in comparison with a control group. More research is needed to ...

Tele-nursing in patients with chronic illness: a systematic review

“…Pero el soporte virtual, el seguimiento telefónico y los dispositivos electrónicos requieren un mínimo de destreza electrónica para el cual nuestra sociedad puede no estar preparada 15 . Hay estudios 25,51 que señalan que España se encuentra a la cola del uso de nuevas tecnologías en comparación con países que se encuentran más desarrollados en este aspecto, como pueden ser Estados Unidos o Australia. Los resultados encontrados en la presente revisión confirman que el perfil del paciente es una de las barreras para el uso de la tele-enfermería, y se relaciona con el incremento de la edad 27,49 ; los pacientes que en la actualidad conviven con uno o varios procesos crónicos son personas que no están familiarizados con las nuevas tecnologías (uso de dispositivos electrónicos y/o soportes virtuales).…”

“…Un 56% (n=19) de los estudios seleccionados 10,14,16,18,20,[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] identificaron el soporte virtual como una de las principales características de la tele-enfermería. Se caracteriza principalmente por el uso de páginas web o videos con fines educativos 25,27 , incluyendo formularios auto-evaluativos, enlaces a páginas web de interés y cursos de formación para fomentar un mayor automanejo y adaptación del paciente con el proceso crónico 30 . Existen también soportes virtuales que incluyen una plataforma para realizar video conferencias entre el profesional sociosanitario y el paciente 25 .…”

La mayoría de los estudios que identifican la video conferencia 20,25,27,34 aluden a la reunión online entre el profesional de enfermería y el paciente, favoreciendo una relación enfermera-paciente consciente, donde el paciente es el verdadero protagonista, convirtiéndose progresivamente en el experto de su proceso 10,26,27,[30][31][32][33] .…”

“…Los dispositivos electrónicos tienen como objetivo principal fomentar el cuidado de los pacientes mediante el uso de aplicaciones electrónicas, como Care4Life 27 o MedSentry 41 , que permiten al paciente adquirir mayor autonomía y desarrollo de habilidades de conocimiento sobre su proceso, logrando un mayor automanejo del paciente 20,47 . Dichas aplicaciones abordan aspectos tales como preguntas recurrentes, sintomatología específica de la enfermedad, medicamentos habituales, hábitos de vida saludables o prevención de complicaciones 8,10,25,36,39,45,48 e, independientemente del tipo de dispositivo, favorecen una relación enfermera-paciente constante y directa, ya que constan de chats, de llamadas y de vídeos 10,20,25,34 .…”

Increasing Physical Activity in Mothers Using Video Exercise Groups and Exercise Mobile Apps: Randomized Controlled Trial (Preprint)

“…Technology interventions have a growing evidence base for being effective at increasing activity, though this research is in its early stages [30][31][32][33]. Additionally, videoconferencing tools such as Google Hangouts and Skype have been tested for exercise video coaching but not as a way to bring participants, and mothers specifically, together for real-time exercise video groups [34].…”
