This secondary analysis used data from the Just in TIME randomized controlled trial, including girls aged 9\u201313\u00a0years with FAPDs. Both girls and their parents completed the Children\u2019s Somatic Symptoms Inventory (gastrointestinal distress (CSSI-GI) and somatic distress (CSSI-nonGI) subscales) and answered questions about general health and mental health symptoms, measures at baseline and after 8\u00a0months. Agreement was assessed using intra-class correlation (ICC) and linear-weighted Cohen\u2019s kappa. Data from 121 girls (mean age 10.6\u00a0years) and their parents were analysed. For CSSI-GI, mean scores were similar at baseline (girls 6.98, parents 7.27; ICC 0.84,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u2009.001) and follow-up (girls 4.25, parents 4.16; ICC 0.91,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u2009.001).
