Efficacy of Mobile Instant Messaging-Delivered Brief Motivational Interviewing for Parents to Promote Physical Activity in Pediatric Cancer Survivors: A Randomized Clinical Trial.

ABSTRACT:

Importance

Physical activity has beneficial effects that mitigate cancer- and treatment-related late effects. However, children who survive cancer are often physically inactive. Brief motivational interviewing may be an effective approach for increasing children's physical activity levels.

Objective

To examine the effects of mobile instant messaging-delivered brief motivational interviewing for parents in promoting regular physical activity in children who have survived cancer.

Design, setting, and participants

An assessor-blinded randomized clinical trial was conducted at 2 Hong Kong pediatric oncology outpatient clinics from March 1, 2019, to January 29, 2021. A total of 161 children who had survived cancer, aged 9 to 16 years, and their parents were randomized (1:1) to an intervention or control group.

Interventions

The intervention group received a 6-month mobile instant messaging-delivered brief motivational interviewing using a strategy menu. Parent-child dyads in both groups received a health advice session and were directed to a physical activity website at baseline.

Main outcomes and measures

The primary outcome was the children's physical activity levels at 12-month follow-up, measured by the Chinese University of Hong Kong: Physical Activity Rating for Children and Youth (total sores: 0-10, higher scores indicate greater physical activity levels). Secondary outcomes were cancer-related fatigue levels, handgrip strength, peak expiratory flow rate, and quality of life. Intention-to-treat analysis was performed.

Results

Of the 161 children included in the study, 93 were boys (57.8%), and the mean (SD) age was 12.4 (2.4) years. Generalized estimating equation analyses showed a significant improvement in outcomes in the intervention group compared with the control group: physical activity levels (group-by-time interaction, 6 months: β = 3.09; 95% CI, 2.65-3.53; P < .001; 12 months: β = 3.91; 95% CI, 3.45-4.36; P < .001), cancer-related fatigue (6 months: β = -5.69; 95% CI, -8.03 to -3.35; P < .001; 12 months: β = -9.16; 95% CI, -11.31 to -7.00; P < .001), left handgrip strength (6 months: β = 2.69; 95% CI, 0.96-4.43; P = .002; 12 months: β = 5.52; 95% CI, 3.70-7.33; P < .001), right handgrip strength (6 months: β = 2.75; 95% CI, 1.01-4.50; P = .002; 12 months: β = 5.45; 95% CI, 3.62-7.27; P < .001), peak expiratory flow rate (12 months: β = 28.51; 95% CI, 16.10-40.92; P < .001), and quality of life (6 months: β = 5.01; 95% CI, 1.19-8.82; P = .01); 12 months: β = 14.19; 95% CI, 10.84-17.54; P < .001).

Conclusions and relevance

In this randomized clinical trial, mobile instant messaging-delivered brief motivational interviewing was effective in promoting the adoption and maintenance of regular physical activity and ameliorating cancer- or treatment-related adverse effects in children who survived cancer.

Project description:ImportancePsychoeducational interventions (PEIs), which provide both information and emotional and psychosocial support, may address the unmet needs of the caregivers of adolescent and young adult patients with cancer.ObjectiveTo explore the effects of an instant messaging-delivered PEI on anxiety, depression, quality of life (QOL), and coping and determine whether the intervention reduces caregivers' unmet needs.Design, setting, and participantsThis randomized clinical trial using an intention-to-treat protocol was conducted from April 1 to September 14, 2022, in a tertiary cancer hospital in China and included caregivers of patients diagnosed with cancer at age 15 to 39 years recruited using convenience sampling.InterventionCaregivers were allocated 1:1 using a randomized block scheme to the intervention or control group. The intervention group received a 5-week PEI and usual care, whereas the control group received only usual care. The PEI was delivered through articles and calls through an instant messaging application.Main outcomes and measuresThe primary outcomes were changes in the levels of caregivers' anxiety and depression, measured using the 7-Item Generalized Anxiety Disorder Scale and the Patient Health Questionnaire 9, respectively. The secondary outcomes were changes in the levels of caregivers' QOL, coping, and unmet needs.ResultsOf the 160 participants, 92 (57.5%) were male; mean (SD) age was 40.27 (8.33) years. Compared with the control group, the intervention group had significantly greater reduction in severity of anxiety (B = -3.231; 95% CI, -4.746 to -1.716; P < .001) and depression (B = -3.253; 95% CI, -5.052 to -1.454; P < .001), smaller reduction in QOL (B = 13.574; 95% CI, 0.488-26.661; P = .04), and greater reduction in unmet needs (B = -12.136; 95% CI, -18.307 to -5.965; P < .001) after the intervention. Twelve weeks after baseline, the intervention group demonstrated a significantly greater reduction only in severity of anxiety (B = -1.890; 95% CI, -3.382 to -0.397; P = .01).Conclusions and relevanceIn this randomized clinical trial of a mobile instant messaging-delivered PEI, caregivers' unmet needs, anxiety, and depression decreased significantly and QOL declined at a significantly slower rate immediately after the intervention in the intervention group compared with the control group. A sustained effect on anxiety was observed 12 weeks after baseline.Trial registrationChinese Clinical Trial Registry identifier: ChiCTR2200055951.

Project description:BACKGROUND:Advances in mobile communication technologies provide a promising avenue for the delivery of tobacco dependence treatment. Although mobile instant messaging (IM) apps (eg, WhatsApp, Facebook messenger, and WeChat) are an inexpensive and widely used communication tool, evidence on its use for promoting health behavior, including smoking cessation, is scarce. OBJECTIVE:This study aims to explore the perception of using mobile IM as a modality to deliver a proposed chat intervention for smoking cessation in community smokers in Hong Kong, where the proportion of smartphone use is among the highest in the world. METHODS:We conducted 5 focus group, semistructured qualitative interviews on a purposive sample of 15 male and 6 female current cigarette smokers (age 23-68 years) recruited from the community in Hong Kong. All interviews were audiotaped and transcribed. Two investigators independently analyzed the transcripts using thematic analyses. RESULTS:Participants considered mobile IM as a feasible and acceptable platform for the delivery of a supportive smoking cessation intervention. The ability to provide more personalized and adaptive behavioral support was regarded as the most valued utility of the IM-based intervention. Other perceived utilities included improved perceived psychosocial support and identification of motivator to quit. In addition, participants provided suggestions on the content and design of the intervention, which may improve the acceptability and usability of the IM-based intervention. These include avoiding health warning information, positive messaging, using former smokers as counselors, and adjusting the language style (spoken vs written) according to the recipients' preference. CONCLUSIONS:This qualitative study provides the first evidence that mobile IM may be an alternative mobile health platform for the delivery of a smoking cessation intervention. Furthermore, the findings inform the development of a chat-based, IM smoking cessation program being evaluated in a community trial.

Project description:BackgroundAlthough the most effective methods of contraception are available in Bolivia, unmet need for contraception among women aged 15 to 19 years is estimated to be 38% (2008), and the adolescent fertility rate is 71 per 1000 women (2016). Mobile phones are a popular mode to deliver health behavior support. We developed a contraceptive behavioral intervention for young Bolivian women delivered by mobile phone and guided by behavioral science. The intervention consists of short instant messages sent through an app over 4 months.ObjectiveThis trial aimed to evaluate the effect of the intervention on young Bolivian women's use of and attitudes toward the effective contraceptive methods available in Bolivia.MethodsThis was a parallel group, individually randomized superiority trial with a 1:1 allocation ratio. Women were eligible if they were aged 16 to 24 years, owned a personal Android mobile phone, lived in La Paz or El Alto, reported an unmet need for contraception, and could read Spanish. The target sample size was 1310 participants. Participants allocated to the intervention had access to an app with standard family planning information and intervention messages. Participants allocated to the control group had access to the same app and control messages. Coprimary outcomes were use of effective contraception and acceptability of at least one method of effective contraception at 4 months. Secondary outcomes were use of effective contraception during the study, acceptability of the individual methods, service uptake, unintended pregnancy, and abortion. Process outcomes included knowledge, perceived norms, personal agency, and intention. Outcomes were analyzed using logistic and linear regression. We also asked participants about physical violence.ResultsA total of 640 participants were enrolled, and 67.0% (429) of them contributed follow-up data for the coprimary outcome, the use of effective contraception. There was no evidence that use differed between the groups (33% control vs 37% intervention; adjusted odds ratio [OR] 1.19, 95% CI 0.80 to 1.77; P=.40). There was a borderline significant effect regarding acceptability (63% control vs 72% intervention; adjusted OR 1.49, 95% CI 0.98 to 2.28; P=.06). There were no statistically significant differences in any of the secondary or process outcomes. The intervention dose received was low. In the control group, 2.8% (6/207) reported experiencing physical violence compared with 1.9% (4/202) in the intervention group (Fisher exact test P=.75).ConclusionsThis trial was unable to provide definitive conclusions regarding the effect of the intervention on use and acceptability of effective contraception because of under recruitment. Although we cannot strongly recommend implementation, the results suggest that it would be safe and may increase the acceptability of effective contraception if the intervention messages were offered alongside the download of the app.Trial registrationClinicalTrials.gov NCT02905526; https://clinicaltrials.gov/ct2/show/NCT02905526.

Project description:Unintended pregnancy is associated with poorer health outcomes for women and their families. In Tajikistan, around 26% of married 15-24 year old women have an unmet need for contraception. There is some evidence that interventions delivered by mobile phone can affect contraceptive-related behaviour and knowledge. We developed an intervention delivered by mobile phone app instant messaging to improve acceptability of effective contraceptive methods among young people in Tajikistan.This was a randomized controlled trial among Tajik people aged 16-24. Participants allocated to the intervention arm had access to an app plus intervention messages. Participants allocated to the control arm had access to the app plus control messages. The primary outcome was acceptability of at least one method of effective contraception at 4 months. Secondary outcomes were use of effective contraception at 4 months and during the study, acceptability of individual methods, service uptake, unintended pregnancy and induced abortion. Process outcomes were knowledge, perceived norms, personal agency and intention. Outcomes were analysed using logistic and linear regression. We conducted a pre-specified subgroup analysis and a post-hoc analysis of change in acceptability from baseline to follow-up.Five hundred and seventy-three participants were enrolled. Intervention content was included on the app, causing contamination. Four hundred and seventy-two (82%) completed follow-up for the primary outcome. There was no evidence of a difference in acceptability of effective contraception between the groups (66% in the intervention arm vs 64% in the control arm, adjusted OR 1.21, 95% CI .80-1.83, p =?0.36). There were no differences in the secondary or process outcomes between groups. There was some evidence that the effect of the intervention was greater among women compared to men (interaction test p =?0.03). There was an increase in acceptability of effective contraception from baseline to follow-up (2% to 65%, p <?0.001).The whole intervention delivered by instant messaging provided no additional benefit over a portion of the intervention delivered by app pages. The important increase in contraceptive acceptability from baseline to follow-up suggests that the intervention content included on the app may influence attitudes. Further research is needed to establish the effect of the intervention on attitudes towards and use of effective contraception among married/sexually active young people.Clinicaltrial.gov NCT02905513 .
