Randomization description
This is a two-arm parallel randomized controlled trial. The unit of randomization is individual. After eligibility assessment, written informed consent, and completion of the pre-test, participants are randomly allocated to the intervention group (n=40) and the control group (n=40) with a 1:1 allocation ratio. Simple randomization was used; no quasi-random methods such as hospital sequence, day of week, or file number were applied. No stratified or blocked randomization was used, and the study is not cluster-randomized. The random sequence is generated using random number generation software (SPSS/R or Random.org) with a 1:1 ratio for 80 participants. For allocation concealment, the generated sequence is placed in opaque, sealed, sequentially numbered envelopes by a research collaborator independent of recruitment and screening. Each envelope is opened only after participant registration and completion of the pre-test, in sequential order. Group allocation is performed by a person not involved in screening or intervention delivery. The study is open-label; participants and the intervention facilitator are aware of group assignment, and no blinding was performed. To reduce bias, data analysis will be conducted using group codes without revealing group labels and based on the intention-to-treat principle.

Other design features
This study is a parallel two-arm (intervention and control) randomized controlled trial (RCT). Its unique design feature is the application of a mixed-methods approach, specifically a Sequential Explanatory Design. Accordingly, the research is conducted in two consecutive phases: the first phase comprises a randomized controlled trial with repeated measures (pre-test, post-test, and one-month follow-up) for quantitative data collection and analysis. In the second phase, following the analysis of quantitative data, qualitative data are collected through semi-structured interviews with a subsample of the intervention group to provide a deeper explanation of the findings and to understand the participants' lived experiences. These qualitative data will be analyzed using thematic analysis. This mixed-methods design enables a more comprehensive understanding of how and why the intervention works.

Intervention groups

1

Description
Intervention group: 9 sessions of integrated logotherapy and life coaching intervention delivered in a group format, twice a week (each session 60-75 minutes). The first 4 sessions focus on logotherapy principles including "Will to Meaning," freedom and responsibility, creative values (meaningful creation), experiential values (depth of life moments), and attitudinal values (suffering as an existential task), culminating in the development of a personal "Meaning Statement." The next 4 sessions utilize the T-GROW model (Topic, SMART Goal setting, Reality assessment using the CIA model, Options exploration, and Will/Action planning) to translate existential insights into practical goals and actionable plans. The final session (9th) is dedicated to integration, reflection, and designing a maintenance plan. The intervention is delivered by a trained researcher in logotherapy and coaching.
