Mental health outcomes in patients with cancer diagnosis: Data showing the influence of resilience and coping strategies on post-traumatic growth and post-traumatic symptoms

The presented data provide a panoramic concerning the influence of different coping strategies in the relationship between resilience and post traumatic growth or post-traumatic symptoms in patients with a cancer diagnosis. These expand the results presented in the related research article of Gori et al. [1], entitled “Pathways to post-traumatic growth in cancer patients: moderated mediation and single mediation analyses with resilience, personality, and coping strategies”. A sample of 154 patients completed a survey, where the Post-Traumatic Growth Inventory, Impact of Event Scale-Revised, Connor-Davidson Resilience Scale, and Coping Orientation to Problems Experienced were included. All the measures for the data collection were in their Italian versions. Data were elaborated by performing single mediation analyses, considering each time the different coping strategies as mediators. The dataset (.xlsx) includes the survey scores, while the tables and figures provide the analysed data, where the mediation models are shown. These data may provide useful bases for future research concerning mental health outcomes in patients with cancer and for tailored programs in preventive or intervention perspectives.

Value of the Data
• The presented data describe significant relationships between resilience, coping strategies and post-traumatic growth or post traumatic symptoms in subjects who received a cancer diagnosis. • These data highlight different mental health outcomes of patients with cancer and may be useful for researches and professionals working in the oncology sector. • The data will be useful for researchers who want to conduct comparative studies about the influence of resilience and coping strategies on post-traumatic growth and post-traumatic symptoms in populations with different traumatic life events. • In the sphere of an application perspective, these data may be useful as a theoretical support in the elaboration of interventions strategies for improving mental health of cancer patients.

Data Description
The survey includes the Post-Traumatic Growth Inventory ( [2] which was administered in its Italian version of Prati and Pietrantoni [3] ), Impact of Event Scale-Revised ( [4] which was administered in its Italian version of Craparo, Faraci, Rotondo, and Gori [5] ), Connor-Davidson Resilience Scale ( [6] which was administered in its Italian version of Di Fabio and Palazzeschi [7] ), and Coping Orientation to Problems Experienced ( [8] which was administered in its Italian version of Sica and colleagues [9] ). The dataset (.xlsx file) includes the questionnaires' total scores of 154 individuals (15 males and 139 females) with a cancer diagnosis and an age ranging from 18 to 79 years ( M = 51.35; SD = 11.25). Table 1 describes the models indexes of the mediations of different coping strategies in the relationship between resilience and post-traumatic growth.
Figs. 1-5 show the mediation models concerning the relationship between resilience and post-traumatic growth. Table 2 describes the models indexes of the mediations of different coping strategies in the relationship between resilience and impact of trauma. Fig. 6 -10 show the mediation models concerning the relationship between resilience and impact of event.  Relationship between resilience and post-traumatic growth with avoidance coping strategy as mediator.

Participants and procedure
A cross-sectional research design was implemented. A sample of 154 individuals with a cancer diagnosis filled the self-report measures in approximately 20 min. They were recruited in various Italian Associations for cancer research and for the support of people with cancer. Respondents were informed about the aim of the research; their participation was voluntary and anonymous and they signed a written informed consent before starting to complete the survey. The questionnaires were administered by qualified staff authorized to use psychological tests. The research was conducted in accordance with the updated ethical standards and the protocol was approved by the Ethical Committee of the Integrated Psychodynamic Psychotherapy Institute (IPPI) (ethical approval number 002/2019).

Measures
The Italian Post-Traumatic Growth Inventory (I-PTGI) [3] was used to assess positive outcomes reported by persons who have experienced traumatic life events [2] . The scale consists of 21 items scored on a 6-point Likert scale from 0 ("I did not experience this change as a result of my crisis ") to 5 ("I experienced this change to a very great degree as a result of my crisis"). Five subscales were identified: New Possibilities (5 items); Relating to Others (7 items); Personal Strength (4 items); Spiritual Change (2 items); and Appreciation of Life (3 items). In this dataset, the inventory showed good internal consistency, with a Cronbach's alpha ranging from 0.72 to 0.89 for the subscales and α = 0.94 for the total scale.
The Italian Impact of event scale -revised (I-IES-R) [5] was used to assess self-reported posttraumatic distress and symptoms [4] . The scale consists of 22 items scored on a 5-point Likert scale ranging from 0 ("not at all ") to 4 ("extremely "). Three subscales were identified: Intrusion (8 items); Avoidance (8 items); and Hyperarousal (6 items). In this dataset, the measure showed satisfactory internal consistency, with a Cronbach's alpha of 0.89 for the total score and α = 0.67, α = 0.85, α = 0.82 for the subscales.
The Italian 10-item Connor-Davidson Resilience Scale (I-CD-RISC-10) [7] was used to assess selfperceived resilience [6] . The scale consists of 10 items scored on a 6-point Likert scale ranging from 0 ("Not true at all ") to 5 ("True nearly all the time "). In this dataset, the measure showed good internal consistency, with a Cronbach's alpha of 0.85.

Statistical analysis
Data entry and analysis were performed using Statistical Package for the Social Sciences (SPSS) software (IBM-SPSS 25.0 version, IBM, Armonk, NY, USA) for Windows. The influences of the coping strategies in the relationships between Resilience and Post-traumatic growth or impact of event were explored by implementing several single mediations using model 4 in macro-program PROCESS 3.4 [10] . The indirect effects were estimated by implementing the bootstrapping technique with 95% CI at 50 0 0 samples.
