School environments can play a key role in improving young people\u2019s mental health. Learning Together for Mental Health is a whole-school intervention aiming to promote mental health and well-being among young people in secondary schools. Before progressing to a Phase III effectiveness evaluation of the intervention, it is critical to assess the feasibility of trial measures at baseline and follow-up.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To evaluate the feasibility of trial measures and procedures within a feasibility study of a whole-school intervention aiming to promote mental health and well-being among young people in secondary schools, including whether we met our progression criterion of survey response rates of 60% or more in two or more schools at baseline and follow-up.<\/jats:p>\n <\/jats:sec>\n \n Design and methods<\/jats:title>\n We conducted a feasibility study which included assessment of the indicative primary and secondary outcomes measures and procedures to be used in a future Phase III trial.<\/jats:p>\n <\/jats:sec>\n \n Setting and participants<\/jats:title>\n Setting for our feasibility study included five state, mixed-sex secondary schools in southern England (one of which dropped out after baselines and one of which replaced this). We recruited year-7 students to participate in the baseline survey and year-10 students to participate in the follow-up survey at 12-month follow-up. Baseline and follow-up participants were different groups, as the focus was assessing feasibility of measures for the age groups that would be surveyed at baseline and follow-up in a Phase III randomised controlled trial. Our study was not powered or designed to estimate intervention effects.<\/jats:p>\n <\/jats:sec>\n \n Interventions<\/jats:title>\n As part of our feasibility study, all schools received the Learning Together for Mental Health intervention for one academic school year.<\/jats:p>\n <\/jats:sec>\n \n Main outcome measures<\/jats:title>\n The indicative primary outcome measure trialled was the total difficulties score of the Strengths and Difficulties Questionnaire. Indicative secondary outcomes measures trialled were the: Warwick-Edinburgh Mental Well-being Scale; Short Moods and Feelings Questionnaire; Generalised Anxiety Disorder-7 scale; Eating Disorders Examination \u2013 Questionnaire Short, self-harm (single item from the Health Behaviour in School-aged Children study); bullying victimisation (Gatehouse Bullying Scale); cyberbullying (two items adapted from the Dose Adjustment for Normal Eating II questionnaire); substance use (National Health Service measure); and Beyond Blue School Climate Questionnaire.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Trial measures and procedures were feasible to implement and were acceptable to year-7 and year-10 students, teachers and parents. At baseline, response rates ranged from 58% to 91% between schools. Only two students were opted out by parents, and no students opted out in advance. Students refusing consent on the day of survey was rare (7%). Twelve per cent of students were absent. The follow-up survey had an overall response rate of 66%, ranging from 44% to 91%. Only two students were opted out by parents, and three students opted out in advance. Overall, 12% opted out on the day. Twenty per cent of students were absent. Variation in response rate reflected specific problems at certain schools. Surveys took 40\u201345 minutes at baseline and 30 minutes at follow-up. The trial progression criterion concerning response rates was achieved, with three of four schools at baseline and two of four schools at follow-up having responses rates above 60%.<\/jats:p>\n <\/jats:sec>\n \n Limitations<\/jats:title>\n Our study involved a small, purposive sample of schools and students which are not representative of those in England.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n With some minor amendments, trial measures and procedures should be applied in a future Phase III effectiveness evaluation of the Learning Together for Mental Health intervention.<\/jats:p>\n <\/jats:sec>\n \n Future work<\/jats:title>\n Survey response rates could be improved if baseline and follow-up surveys are not scheduled in the last weeks of term, on Fridays or near mock General Certificate of Secondary Education exams. Completion of some measures (such as Eating Disorders Examination \u2013 Questionnaire Short) among year-7 students may be improved if question wording is tailored to be age-appropriate.<\/jats:p>\n
