  1. CO: constipation; DY: dyspnea; FA: fatigue; FI: financial difficulties; PA: pain; PF: physical functioning; RCOPE (−): negative religious coping; SL: insomnia; SOC: sense of coherence.
  2. Coding of the independent variables: age (continuous variable), education (lower education: high school and lower levels; higher education: college and university), disease stage (mild: 0 to II or severe: III and higher), surgery type (mastectomy or conservation surgery), and treatment modalities at the 6-month follow-up (ongoing treatment or treatment ended).
  3. \( \widehat{\upbeta} \): Standardized regression coefficient.
