The Relationship Between Time Perspective, Fear of Cancer Recurrence, Rumination, and Catastrophizing in Gastric Cancer Survivors

Primary outcomes

1. Time perspective

   Time frame: through study completion, an average of 1 year

   The Chinese version of ZIPI scale was adopted for the measurement of time perspective, ZIPI scale is the current international common measurement tool.ZTPI scale was developed by Zimbardo et al. in 1999, which is mainly used for assessing individual's time perspective, the scale has been translated by scholars from many countries, and has good cross-cultural applicability. The Chinese version of the ZTPI scale was Chineseized and revised by Wang Chen in 2016, and the revised scale can be divided into five dimensions of past negativity (7 entries), past positivity (6 entries), present impulsivity (4 entries), future (5 entries), and present predestination (3 entries), with a total of 25 entries after exploratory factor analysis.All questions are scored on a scale of 1 (strongly disagree) to 5 (strongly agree), with higher scores indicating a greater tendency towards certain time perspective.

2. Catastrophizing

   Time frame: through study completion, an average of 1 year

   Catastrophizing was measured using the 4-item Cognitive Emotion Regulation Questionnaire Catastrophizing subscale ( CERQ-CS ). Chinese scholars such as Zhu Xiongzhao (2007) revised the Cognitive Emotion Regulation Questionnaire (CERQ) to form the Chinese version of the Cognitive Emotion Regulation Questionnaire (CERQ-C) applicable to the Chinese version.Each item of the CERQ - CS has 5 responses ranging from 1 (almost never) to 5 (almost always). Higher total scores on this subscale indicate higher levels of catastrophizing, and this subscale has good reliability in the Chinese population, the minimum value is 4 points, and the maximum value is 20 points

3. Rumination

   Time frame: through study completion, an average of 1 year

   Intrusive rumination was measured using the Event-Related Rumination Rumination Questionnaire (ERRI). It is scored according to how many rumination the subjects have produced in the last two weeks and the number of scores is used to assess the degree of rumination of the individual. It was revised by Zhou Xiao et al. (2014) to Cann et al.'s (2010) Event-Related Rumination Questionnaire, which included two dimensions of intrusive rumination and active rumination, with a total of 20 questions. After the revision, the questionnaire had good internal consistency coefficients for the total and dimensions, and the validity indicators also reached a good level. Each item is rated on a 4 point scale, and the scores of the Intrusive rumination scales range from 0 to 30 points The higher the score, the higher the level of invasive rumination.

4. Fear of cancer recurrence

   Time frame: through study completion, an average of 1 year

   The Chinese version of the Fear of Disease Progression Simplified Scale (FoP-Q-SF) was used to measure the degree of fear of recurrence in cancer patients. Our researchers and scholars, Wu Qiyun et al. translated and Chineseized the FoP-Q-SF according to Chinese characteristics to form a version of the Fear of Progression of Disease Simplified Scale suitable for cancer patients in China. There are 12 questions in total, the higher the score, the higher the level of fear of recurrence. When the score is between 12 and 23, it indicates that the patient is at a low level of fear recurrence. When the score is between 24 and 36, it indicates that the patient is at a moderate level of fear recurrence. When the score is between 36 and 60, it indicates that the patient is at a high level of fear recurrence.
