结局指标
主要结局
Change in Protective Behavioral Strategies for Marijuana (PBSM-17) used
时间窗: 8 weeks
The French version of the questionnaire translated by Côté et al. (2021) will be used. The 17 items proposed in the scale, each representing a behavioral protection strategy, are measured in terms of frequency of use on a six-point Likert-type scale (never, rarely, occasionally, sometimes, often and always). As indicated by its developers, the total score of the PBSM-17 is obtained by calculating the total score of each item and then converting this raw score into a standardized form (T-score) ranging from 15 to 73.
