    Two-year treatment effects of the common elements treatment approach (CETA) for reducing intimate partner violence and unhealthy alcohol use in Zambia.

    BACKGROUND: Intimate partner violence (IPV) and unhealthy alcohol use are common yet often unaddressed public health problems in low- and middle-income countries. In a randomized trial, we found that the common elements treatment approach (CETA), a multi-problem, flexible, transdiagnostic intervention, was effective in reducing IPV and unhealthy alcohol use among couples in Zambia at a 12-month post-baseline assessment. In this follow-up study, we investigated whether treatment effects were sustained among CETA participants at 24-months post-baseline. METHODS: Participants were heterosexual couples in Zambia in which the woman reported IPV perpetrated by the male partner and in which the male had hazardous alcohol use. Couples were randomized to CETA or treatment as usual plus safety checks. Measures were the Severity of Violence Against Women Scale (SVAWS) and the Alcohol Use Disorders Identification Test (AUDIT). The trial was stopped early upon recommendation by the trial's DSMB due to CETA's effectiveness following the 12-month assessment. Control participants exited the study and were offered CETA. This brief report presents data from an additional follow-up assessment conducted among original CETA participants at a 24-month visit. RESULTS: There were no meaningful changes in SVAWS or AUDIT scores between 12- and 24-months. The within-group treatment effect for SVAWS from baseline to 24-months was CONCLUSIONS: The lack of change in levels of IPV and unhealthy alcohol use between the 12- and 24-month post-baseline timepoints suggests that treatment gains were sustained among participants who received CETA for at least two years from intervention commencement.

    WASH and learn: a scoping review of health, education and gender equity outcomes of school-based water, sanitation and hygiene in low-income and middle-income countries.

    School-age children in low-income and middle-income countries (LMICs) face health and educational challenges due to inadequate water, sanitation and hygiene (WASH) in schools (WinS). Evidence for the impact of WinS interventions is limited and inconsistent, and previous systematic reviews have faced challenges in synthesising data due to varied interventions, study designs and outcome measures, although most do not examine this variability in more detail. This scoping review identified 83 experimental studies from 33 LMICs measuring a primary or secondary health or educational outcome among pupils, published up to November 2023, using a systematic search of seven databases and searching of reference lists of previous systematic reviews and included articles. These included 65 studies (78%) not included in previous WinS reviews and encompassed 313 intervention effects across 14 outcome domains. Interventions comprised an array of WASH technologies and approaches, often combining infrastructure and behaviour change methods and frequently integrated with other school-based initiatives like deworming. 36 studies (43%) measured only behavioural or knowledge outcomes. Our comprehensive inventory of study outcomes identified 158 unique outcome measures, with 72% measured in exactly one study. Common outcomes included parasitic infections, anthropometric measures and school absence, but approaches to measurement varied widely even for similar outcomes. Only 7% of results were disaggregated by gender, limiting assessment of differential impacts. Our findings underscore the need for standardised outcome measures in WinS research incorporating a complete definition of the assessment and aggregation approach, greater attention to gender-specific impacts, and further exploration of modalities and functions of WinS interventions alongside novel meta-analysis methods to disentangle effects of diverse intervention components.
