| Dyadic Acceptance and Commitment Therapy (ACT) for lung cancer patients and their spouse caregivers addressing FCR and routine care | Other | In addition to routine care provided to the control group, the ACT intervention will be delivered by researchers who have completed formal training in Acceptance and Commitment Therapy (ACT). The intervention will be conducted in a quiet and comfortable demonstration room within the department. The intervention will be delivered in a face-to-face, couple-based format. It will consist of six sessions, with two sessions per treatment cycle, each lasting 35-75 minutes, over a total of three treatment cycles. The intervention will incorporate techniques such as metaphor-based exercises, mindful breathing, body scan, the T-puzzle, and the Chinese finger trap. The preliminary structure is as follows: six fixed in-person sessions (Sessions 1-6), supplemented by online homework assignments completed between sessions. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in fear of cancer recurrence severity of lung cancer patients-The Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) | The scale consists of 9 items, each rated from 0 to 4. Zero is equivalent to "never" and 4 indicates "always". Total scores range from 0 to 36, where 0 indicates no fear of cancer recurrence and 36 indicates the highest possible fear. A score of 13 or higher is defined as subclinical fear of cancer recurrence. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in fear of cancer recurrence severity of spouse caregivers-Fear of Cancer Recurrence Inventory Short Form-Caregiver Version (FCRI-SF-C) | The scale consists of 9 items, each rated from 0 to 4. Zero is equivalent to "never" and 4 indicates "always". Total scores range from 0 to 36, where 0 indicates no fear of cancer recurrence and 36 indicates the highest possible fear. A score of 13 or higher is defined as subclinical fear of cancer recurrence. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in fear of cancer recurrence triggering factors-The Fear of Cancer Recurrence Inventory-Triggering factors (FCRI-T) | This 8-item dimension assesses how often daily triggers elicit fear of cancer recurrence. Each item is scored from 0 to 4. Zero is equivalent to "never" and 4 indicates "always". Total scores range from 0 to 32, where 0 indicates that none of the factors trigger fear and 32 indicates that all factors always trigger fear. |

| Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in psychological flexibility-Comprehensive Assessment of ACT Processes (CompACT) | The CompACT contains 22 items, each scored from 0 to 6. Zero is equivalent to "never" and 6 indicates "always". After reverse-scoring the values and committed action domain (plus four items of the mindfulness and self-as-context domain), total scores range from 0 to 132, where 0 indicates the lowest possible psychological flexibility and 132 indicates the highest possible psychological flexibility. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in illness perception-Brief Illness Perception Questionnaire (B-IPQ) | The B-IPQ includes 8 items, each scored from 0 to 10. Zero is equivalent to "no perception of that aspect" and 10 indicates "extreme perception of that aspect". Total scores range from 0 to 80, where 0 indicates a very benign illness perception and 80 indicates the most threatening illness perception possible. The ninth open-ended item asks participants to list the three most important causal factors. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in dyadic coping-Dyadic Coping Inventory (DCI) | The DCI consists of 37 items, each rated from 1 to 5. One is equivalent to "very rarely" and 5 indicates "very frequently". Total scores range from 35 to 75, where 35 indicates the lowest possible dyadic coping competence and 75 indicates the highest possible dyadic coping competence. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in intimate relationship-Unidimensional Relationship Closeness Scale (URCS) | This 11-item scale uses a 5-point scale from 1 to 5. 1 is equivalent to "strongly disagree" and 5 indicates "strongly agree". The mean of all item scores is calculated, ranging from 1 to 5, where 1 indicates the lowest perceived closeness and 5 indicates the highest perceived closeness. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in family care-Family Adaptation, Partnership, Growth, Affection, Resolve index Questionnaire (Family APGAR Questionnaire) | The Family APGAR has 5 items, each scored from 0 to 2. Zero is equivalent to "hardly ever" and 2 indicates "almost always". Total scores range from 0 to 10, where 0 indicates the poorest family function and 10 indicates the best family function. Scores of 7-10 indicate good family function, 4-6 moderate dysfunction, and 0-3 severe dysfunction. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |
| Change from baseline in quality of life of lung cancer patients-Functional Assessment of Cancer Therapy (FACT-L V4.0) | The FACT-L V4.0 consists of 36 items. Each item is scored from 0 to 4. Zero is equivalent to "not at all" and 4 indicates "very much". Positively worded items are scored 0-4; reverse-worded items are scored 4-0. The total score is the sum of five dimension scores (physical, social/family, emotional, functional, and lung-specific), ranging from 0 to 144, where 0 indicates the poorest possible quality of life and 144 indicates the best possible quality of life. | Baseline, after the third intervention (1.5 months), post-intervention (3 months), 1 month after intervention (4 months) |

| Withdrawal Rate: Percentage of Initially Enrolled Participants Who Voluntarily Withdraw or Are Lost to Follow-Up | Withdrawal rate is calculated as (number of participants who voluntarily withdraw from the study or are lost to follow-up after enrollment / total number of participants initially enrolled) × 100%. The rate ranges from 0% to 100%. | Post-intervention (3 months) |
| Number of Participants with Study-Related Adverse Events as Assessed by CTCAE v4.0 | The study uses a self-developed Adverse Event Form to document study-related adverse events (AEs) occurring during the study period. The incidence rate is calculated as (number of participants experiencing at least one study-related AE / total number of enrolled participants) × 100%. Severity grading follows the CTCAE v4.0. | Intervene in the whole process (3 months) |
| Satisfaction with the Intervention Program as Assessed by Qualitative Interviews | Semi-structured interviews are conducted by the investigator using a final interview guide developed through group brainstorming and revised by a nursing professor experienced in qualitative research. Sampling continues until no new themes emerge and meaning saturation is achieved. Thematic analysis is used to identify satisfaction-related patterns, and findings are reported with representative quotes. No predefined numeric threshold is applied. | Post-intervention (3 months) |
