Translation and Cultural Adaptation of an E-Health Program to Promote Positive Mental Health Among Family Caregivers in Portugal

<b>Introduction:</b> Caring for a dependent individual, particularly over an extended period, places significant strain on family caregivers, often leading to adverse physical, mental, emotional, social, and economic outcomes for both caregivers and those they care for. Common challenges include anxiety, depression, loneliness, and diminished overall well-being. E-health applications have emerged as effective tools to support family caregivers by promoting positive mental health through online interventions, enhancing problem-solving skills, autonomy, interpersonal relationships, self-control, and a prosocial attitude. <b>Methods:</b> This study aimed to translate and culturally adapt the Spanish "Program to Promote Positive Mental Health through the Cuidadoras Crónicos Manual" into the Portuguese context, supporting its implementation as a smartphone application. The process involved translation, back-translation by two native experts, and refinement through a focus group with eight participants. The study adhered to the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines. <b>Results:</b> The translation and back-translation processes identified several adjustments, which informed discussions in the focus group. Three key themes emerged: (i) conceptual and semantic equivalence, (ii) optimisation of content, and (iii) relevance and timeliness of the manual. <b>Conclusions:</b> The Spanish manual for promoting positive mental health among family caregivers was successfully translated and culturally adapted into European Portuguese. Validated through expert input, this marks the first version of the manual tailored to Portuguese caregivers, using Positive Mental Health models to support caregivers of individuals with chronic conditions.
