Inclusion criteria

Inclusion criteria: Insomnia diagnosis: Score above the cut-off on the Insomnia Severity Index (ISI) indicating clinical insomnia. Surgery type: Candidate for elective planned surgery (to ensure sufficient time to complete 4 to 6 sessions of the CBT-I protocol prior to surgery). Age: Adult age range (usually 18 to 65 years, depending on the type of surgery)Informed consent: Ability and willingness to provide written consent to participate in the study and adhere to CBT-I training sessions.. Cognitive ability: Ability to read, write, and understand Persian to complete questionnaires and understand the content of the training sessions. Medication stability: Having a consistent medication pattern (especially for sleep-related medications) for the past two weeks.000

Exclusion criteria

Exclusion criteria: Secondary sleep disorders: Diagnosed sleep disorders other than primary insomnia (such as obstructive sleep apnea, severe restless leg syndrome, or narcolepsy). Acute psychological conditions: History of severe untreated psychiatric disorders (such as schizophrenia, bipolar disorder, psychosis, or suicide attempt in the past 6 months). Substance use: Active abuse of alcohol or illicit substances.Severe underlying diseases: Uncontrolled systemic conditions that may directly affect inflammatory response or wound healing (such as uncontrolled diabetes, severe immunodeficiency, or long-term systemic corticosteroid use). Emergency or high-risk surgery: Change in surgical status from elective to emergency, or surgeries with very high risk disrupting the study protocol timeline. Concurrent interventions: Receiving other psychotherapies or behavioral sleep interventions simultaneously during the study period. Pregnancy or breastfeeding: Due to physiological changes in sleep and inflammatory responses during this period.

Design outcomes

Primary

MeasureTime frame
Rate and quality of surgical wound healing assessed by ASEPSIS scoring system and Southampton wound assessment scale. Timepoint: Day 3, Day 7, and Day 14 post-surgery. Method of measurement: Wound assessment by trained physician or nurse using the ASEPSIS scoring system and Southampton wound assessment scale; higher scores indicate greater impairment in wound healing.;> Level of systemic inflammatory response measured by serum CRP, IL-6, and TNF-a markers. Timepoint: Before CBT-I intervention, and 24 to 72 hours post-surgery. Method of measurement: Measurement of serum levels of CRP, IL-6, and TNF-a from patient blood samples in the laboratory.;Postoperative clinical outcomes including complication severity, recovery quality, and patient satisfaction. Timepoint: At discharge, Day 7, and Day 30 post-surgery. Method of measurement: Complications assessed by Clavien-Dindo classification, recovery by Postoperative Recovery Profile (PRP), and patient satisfaction by Surgical Satisfaction Questionnaire (SSQ-8).

Secondary

MeasureTime frame
Sleep quality including sleep latency, sleep duration, sleep disturbances, and daytime functioning. Timepoint: Before CBT-I intervention, day of surgery, and Day 14 post-surgery. Method of measurement: Pittsburgh Sleep Quality Index (PSQI) with 19 items and 7 subscales; total score 0–21; higher scores indicate poorer sleep quality.;Severity of difficulty in sleep onset, sleep maintenance, early awakening, and functional consequences of insomnia. Timepoint: Before CBT-I intervention, day of surgery, and Day 14 post-surgery. Method of measurement: Insomnia Severity Index (ISI) with 7 items on a 5-point Likert scale; higher scores indicate greater insomnia severity.;Level of anxiety and depression in patients before and after surgery as a mediating variable in the intervention pathway. Timepoint: Before intervention, day of surgery, and Days 7, 14, and 30 post-surgery. Method of measurement: Hospital Anxiety and Depression Scale (HADS); higher scores indicate greater severity of anxiety and depression symptoms.
