evaluation of the impact of a comic-based programme to promote body confidence among adolescents in india

Conditions: Body Image; Eating Disorder Symptom

Summary: body dissatisfaction is a leading concern for young people and can have serious health consequences. emerging approaches for improving body image are effective among adolescents in the school setting. however, the majority of trials are conducted in high-income westernised countries, despite body dissatisfaction being increasingly recognised as a global concern. as such, it is important to develop and disseminate interventions to promote body confidence among adolescents in in low-to-middle income countries, too. one country where body image concerns are becoming an increasing issue is india. the investigators recently finished developing and evaluating a body image programme among adolescents in new delhi, india; which found immediate and 3-month improvements in body image, disordered eating, self-esteem, and other related outcomes. whilst these findings offer an effective body image programme for school students in urban areas of india, this may not be feasible for schools in more rural and lower socio-economic areas in india. the aim of the present study is therefore to conduct an acceptability study, followed by a randomised controlled trial (rct), of a comics-based body image programme among adolescents in a semi-rural area of india (rajasthan), in order to understand its acceptability, feasibility, and preliminary efficacy. this comic-based programme will be based on dove confident me, which was found to be effective among adolescents in delhi, india. to assess the acceptability of the comic-book-based programme, interviews and focus groups will be conducted with students and teachers. this in-depth feedback will be used to optimise the programme. next, an rct will compare body image and well-being of students who take part in the programme to students who do not take part (classes as usual) to examine the programme's efficacy. the investigators will recruit students and teachers from schools in a rural and lower socio-economic area of india (rajasthan). students will complete questionnaire assessments of body image and well-being before and after the 6-session intervention (across 4 weeks), and again at 3-month follow-up to assess longer-term benefits. it is hypothesised that students who receive the intervention will have better body image and wellbeing relative to the control group at both post-intervention and follow-up.

background: body image is a significant and prevalent concern for adolescents in high-income countries such as the uk, the usa, and australia. for example, a national survey of nearly 22,000 young people in australia found that 3 in 10 adolescent boys and girls are concerned about their appearance. this high prevalence of body image concerns is worrisome, given their serious negative physical and psychological health consequences, including unhealthy weight loss behaviours, eating disorders, depression and self-harm, substance use, and lower levels of academic engagement. there is increasing recognition that body dissatisfaction is a global issue. for example, in india, 57% of adolescents report being concerned with their appearance. further, girls across different regions of india have expressed concerns in relation to their weight and report dieting behaviours. skin colour has also been indicated as an additional source of appearance concern among young people in india. indeed, research indicated that 19% of indian undergraduate students had used a skin lightening product in the previous 12 months, strongly suggesting dissatisfaction with their natural skin tone, which may be pertinent to younger groups. collectively, these findings indicate the importance of developing and disseminating interventions to promote positive body image among adolescents in india. the investigators recently finished developing and evaluating a school-based body image programme, 'dove confident me', among adolescents in new delhi, india. immediate and 3-month follow-up improvements were found in body image, disordered eating, self-esteem, and other related outcomes. whilst these findings offer an effective body image programme for school students in urban areas of india, this may not be feasible for schools in more rural and lower socio-economic areas in india, where there is limited electricity and computers. therefore, the aim of the present study is to conduct an acceptability study followed by a randomised controlled trial of a comic-based body image programme among adolescents in a semi-rural area of india (rajasthan), in order to understand its acceptability, feasibility, and preliminary efficacy. this comic-book-based programme will be based on 'dove confident me'. it is hypothesised that students who receive the comic-based body image intervention will experience immediate and sustained improvements in the primary (i.e., body image) and secondary outcomes (i.e., eating pathology, internalisation of appearance ideals, body image-related life disengagement, self-esteem, positive and negative mood) relative to students in the control condition. there are no hypotheses in relation to the impact of the intervention on the exploratory outcomes (i.e., skin colour dissatisfaction, body hair dissatisfaction, appearance-based teasing, endorsement of traditional gender norms). study 1: acceptability study study design a qualitative approach will be adopted to explore students' and teachers' acceptability (i.e., thoughts and feedback) on the comics. online interviews will be conducted with students, whilst online focus groups will be conducted with teachers, both informed by a semi-structured interview schedule. all participants will also be asked a series of quantitative questions exploring acceptability of the comics. recruitment and participants the department of education in rajasthan will select one school which meets the inclusion criteria to participate in the research (see elsewhere). a total of nine teachers who teach across classes 6-8 (three teachers from each year group) will be invited to participate in an online focus group (five teachers in one focus group, four teachers in a second focus group). however, a total of 36 students across classes 6-8 (aged 11-14 years) will be invited to participate in online interviews, whereby the first nine interviews will help in theme identification and the remaining 27 interviews will contribute towards developing a greater understanding of each theme. this sample will be equally divided across the three years, genders, and reading and writing proficiency, which will be assessed by their teachers. this will lead to six girls and six boys in each year group, with three boys and three girls with a higher level of reading and writing proficiency, and three boys and three girls with a lower level of reading and writing proficiency. procedure on behalf of the authors, who are unable to travel to india due to the covid-19 pandemic, an international organization for standardisation-(iso)-certified research agency will collect data. once parents have provided consent for their children to participate in the study, students will provide informed assent. teachers will be provided with information about the study and a consent form. next, each participant will be sent a copy of the six comics to read at home. a week later, the research agency will conduct the online focus groups with teachers and online interviews with students. the interviews and focus groups will be audio-recorded and last between 45-60 minutes. participants will then be asked to complete the brief quantitative questionnaire. data analysis a data management plan will be prepared in line with requirements of university research governance. audio-recordings will be transcribed verbatim and anonymized. transcripts will be simultaneously analysed by two of the authors using qualitative codebook thematic analysis. questionnaire data will be entered into an spss file, and descriptive analyses will be conducted on the data. findings from both the qualitative and quantitative data will be used to optimise the comics and teacher guides prior to their evaluation in the randomised controlled trial (rct). study 2: rct trial design a parallel two-arm, cluster rct will be employed to evaluate the adhafull comic-based intervention. schools will be randomized before completion of t1 data collection. the study design comprises two independent groups with outcome data collected at three time points (t1, t2, t3). t1 is baseline (week 1); t2 is 1-week post-intervention (week 5) at the end of intervention; t3 is 12-weeks follow-up (week 16). the resulting data is amenable to standard analysis for two group comparisons including a 2 by 2 by 2 by mixed factorial design with randomized group as a two level between subjects fixed factor, trial phase (t2, t3) as a longitudinal two-level repeated measures factor, gender as a two-level fixed factor and with the commensurate baseline measure (t1) as a mean adjusted covariate. randomized school will be a random factor in the analyses. following t3 data collection, schools in the control condition will receive all intervention materials, including the training documents for teachers. recruitment and participants government schools in rajasthan will be recruited using stratified sampling based on two key sociodemographic factors: the degree of ruralness of the area within which the school is located, the school's exam results. the main recruitment sites will be identified by rajasthan's department of education, who will select schools that meet the inclusion criteria (see elsewhere). once the school principal provides consent to participate in the research, each school will be randomly allocated to either the intervention or lessons-as-usual control condition. students in classes 6-8 (aged 11 to 14 years) will be invited to participate in the study. sample size calculations the evaluation of 'dove confident me' in an urban indian setting indicated a range of effect sizes for outcome measures with standardized effects in the small to medium range and exceeding an effect size of d = 0.2, which would minimally be of interest to public health policy makers (lewis-smith et al., under review). for a lower bound of d = 0.2, a sample size of n = 540 boys and n = 540 girls per arm would have 95% power to detect an effect separately for each gender (two-sided, alpha = 0.05). to account for 10% loss, the sample size will be inflated by (540/10 =) 54 of each gender per arm, and to account for 10% loss within this additional recruitment, a further inflation of (54/10 =) 6 to give a target sample size of 600 boys and 600 girls per arm, totalling 1,200 per arm (intervention versus control). therefore, a total of 2,400 students will be recruited. students will be equally divided across years 6,7, and 8, and gender. randomization participants will be randomized to either the intervention or control arm at the school level. randomization will be conducted at the school level to avoid spill over effects due to communication about the intervention to the control group. eligible schools will be randomised in a target 1:1 ratio using minimization with a residual error. the minimization factors are (i) number of students at grade 6, 7 or 8 and (ii) proportion of boys at grade 6, 7, and 8. the first 8 schools will be allocated using blocked randomisation thereafter probabilistic minimization will occur with the probability of minimizing set to 0.8. outcome measures there are very few body image and related psychological outcome measures which have undergone rigorous validation in india, and those which have, tend to be in english. the outcome measures that will be used in this trial are currently being validated in hindi by the investigators, with rigorous steps employed (swami \& barron, 2019). the validation will be completed prior to commencing the present study. thus, the final items may differ from those in the original scales below and will be reported in the main trial paper (see outcome measures elsewhere). since the original protocol, concerns regarding the sample's ability to comprehend the measures led to the addition of more visual and less literacy-dependent exploratory measures, which are described under the 'outcome measures' section. other measures demographics demographic information will be collected from students in the t1 questionnaire, including age, gender, religion, language spoken at home, the family's primary wage earner's level of education, parents' occupations, number of bedrooms in the house, and whether certain electronic items are owned by the household (e.g., television, computer). the socio-economic status of participants will be estimated using india's new consumer classification system (nccs; kakati \& ahmed, 2016). intervention acceptability acceptability of the comic-based intervention will again be assessed among students in the intervention condition via the t2 questionnaire. they will be asked to indicate their degree of agreement or disagreement using a five-point likert scale (1 = strongly disagree to 5 = strongly agree) with statements concerning their perceptions of the intervention (e.g., "i enjoyed the lessons", "i understood what was being taught in the lessons", "i think adolescents would find the activities beneficial and interesting"). teachers will also be asked to complete a brief questionnaire to assess intervention acceptability. they will be asked to indicate their degree of agreement or disagreement using a five-point likert scale (1 = strongly disagree to 5 = strongly agree) with statements regarding their perceptions of intervention delivery and student engagement (e.g., "i enjoyed delivering these lessons", "students understood the key messages of these lessons", "i felt confident delivering these sessions"). a subgroup of teachers and students will be invited to participate in separate focus groups or interviews, to explore intervention acceptability in greater depth from both perspectives. attention checks to assess the degree of attention from participants whilst completing each questionnaire, attention checks will be embedded throughout at all three time-points. these items will instruct participants to select a specific response on a likert scale (e.g., please select 'strongly agree'). there will also be attention checks which are specific to each comic's storyline in the t2 survey. these will be used to assess participants' recall of the comics and to determine the number of participants that were present in each session. there will be a question about each comic (e.g., "why does seema's mother stop her from playing outside?"), to which participants will need to select the correct answer from four options (e.g., "she wants seema to study for school", "she says it's too dark to play outside", "i did not attend session 1/do not recognize the story"). intervention fidelity a proportion of sessions will be observed by researchers, and teachers will be asked to audio-record the delivery of their sessions. fidelity assessment will be based on previous school intervention evaluation studies (garbett et al., 2021; diedrichs et al., 2021), whereby a standardised checklist will assess three domains: perceived facilitator competence, the extent to which learning outcomes were met, and adherence to the intervention. sessions with both audio and live observation will be used to assess interrater reliability. procedure ethical guidelines for conducting anonymous public health research in india (indian council of medical research, 2018) indicate that parental consent is sought at the school's discretion. however, with the permission of department of education of rajasthan in india, parents will be given two weeks to provide opt-out consent. additionally, the children will be provided with information about the study and given the opportunity to ask questions before they indicate written assent. the research agency will liaise with each recruited school to decide on an alternative activity for the students without consent/assent. this will take place outside of the classroom where the intervention is being delivered or data collection is occurring. once all consent procedures have been completed, a team of trained researchers from an iso-certified research agency will administer t1 outcome assessments via a self-report paper survey with all students irrespective of randomized arm. all students will complete the surveys in a quiet classroom in the presence of a researcher and schoolteacher and will be encouraged to complete the questions independently (t1). further outcome assessments will be administered via paper questionnaires in the week following the final session of the intervention (t2) and at 12-weeks follow-up (t3). once outcome assessments have been completed by students, the data will be entered into a password-protected excel spreadsheet, and subsequently imported into an spss data file for analysis. a data management plan will be prepared in line with requirements of university research governance. this data will be stored on a secure encrypted network on the university system. with regard to intervention delivery, a 'train-the-trainer' approach will be adopted. this will involve having expert trainers (i.e, the authors, who are experienced in the train-the-trainer approach) teach non-expert providers (i.e., the research agency) how to subsequently train teachers in delivery of the intervention. the train-the-teacher approach has demonstrated efficacy in previous body image intervention evaluations and facilitates scalability and sustainability. the research agency will receive a two-day training course, and subsequently, teachers will receive a one-day training course. the teacher training will cover the theoretical basis of the intervention, including risk factors for body dissatisfaction, and the associated consequences. subsequently, the teachers will be familiarised with the comics and associated activities and will participate in role plays to practise delivering the intervention. finally, they will be given hints and tips for delivering the sessions and practise answering challenging questions that could be posed by the students. all schools in the intervention condition will begin the intervention in the week following t1 outcome assessment. teachers will deliver each session during a school lesson, and the six sessions will be delivered at a rate of two sessions per week. each session will begin with the teacher reading the comic with the class. when finished, the teacher will ask the students for their feedback on the comic and clarify any words/sentences that students struggled to understand. following this, the two activities (activity one being mandatory and activity two optional) associated with the respective comic will take place, with the teacher facilitating these. once discussed and completed, the session will come to an end. statistical analyses the full prospective statistical analysis plan is summarised. analyses will be conducted on an intention-to-treat (itt) basis. additional per protocol (pp) analyses will be performed. the per protocol analysis set will comprise those who provide outcome data and pass attention control checks requiring \>= 80% of all attention control questions to be correctly answered. missing data sensitivity analyses will be performed on both the itt analysis set and the pp analysis set. the primary outcome variable is the besaa. the analysis plan for the secondary outcomes of the ede-q, internalisation-general, bild-q, panas-c and rses, and the exploratory outcome of endorsement of traditional gender norms will be the same as the besaa. a linear mixed model will be used to examine the 2 by 2 by 2 factorial design (randomized arm \[control, intervention\], phase \[t2, t3\], gender \[male, female\]) using a hierarchically balanced model comprising all two-way interactions and two-way interactions with the baseline mean adjusted covariate. the model will additionally include school as a random factor, and a sensitivity analysis relating to the inclusion-exclusion of this effect will be conducted. underpinning model assumptions will be examined. ancova with mean adjusted baseline measure as covariate will be used to compare randomized arms at each of t2 and t3. the homogeneity of regression lines assumption will be assessed. in addition, separate sub-group analyses for boys and girls will be performed. cohen's d and partial eta squared will be used to quantify standardised effect size, along with unadjusted means and 95% confidence intervals. percentages reporting positive change, no change, and a poorer outcome, along with 95% confidence intervals will be reported. this study has multiple outcome measures (moms) at multiple time points. to limit serendipitous conclusions from moms, we will additionally report unadjusted p-values of the secondary outcomes at each of t2 and t3 along with results after controlling the false discovery rate (benjamini \& hochberg, fdr using 0.2) and commit to reflecting this in the conclusions. exploratory analyses exploratory outcome measures of skin colour dissatisfaction, body hair dissatisfaction, and appearance-based teasing, are single ordinal exploratory outcomes and will be compared between randomized groups at each of t2 and t3 using an ordinal logistic link controlling for baseline measures. gender sub-group analyses will also be conducted. additionally, mediation analysis will be used to investigate whether interventional changes in body esteem between t1 and t3, and body esteem at t3, are mediated by changes in internalisation of appearance ideals between t1 and t2, and whether mediation is gender dependent. extra analyses: exploratory visual-based outcome measures of body size satisfaction and skin colour satisfaction are single ordinal exploratory outcomes and will be compared between randomized groups at each of t2 and t3 using an ordinal logistic link controlling for baseline measures. gender sub-group analyses will also be conducted.
