Screening of cannabis-related problems among youth: the CPQ-A-S and CAST questionnaires

<p>Abstract</p> <p>Background</p> <p>Cannabis use among young people is a significant problem, making particularly necessary validated screening instruments that permit secondary prevention. The purpose of this study was to analyze and compare the psychometric properties of the CAST and CPQ-A-S questionnaires, two screening instruments specifically addressing the youth population.</p> <p>Methods</p> <p>Information was obtained on sociodemographics, frequency of substance use, psychopathological symptoms and cannabis-use problems, and the CPQ-A-S and CAST were applied, as well as an infrequency scale for discarding responses made randomly. The sample was made up of 144 young people aged 16 to 20 that had used cannabis in the last month, of which 71.5% were boys. Mean age of the sample was 17.38 years (SD = 1.16).</p> <p>Results</p> <p>The results show that from the psychometric point of view both the CAST and the CPQ-A-S are good screening instruments.</p> <p>Conclusions</p> <p>The CAST is shorter and presents slightly better internal consistency than the CPQ-A-S. Both instruments show high sensitivity and specificity in the detection of young people dependent on cannabis according to the DSM IV-TR criteria. The CPQ-A-S appears to show greater capacity for detecting psychopathological distress associated with use. Both questionnaires yield significant odds ratios as predictors of frequent cannabis use and of the DSM IV-TR abuse and dependence criteria. In general, the CPQ-A-S emerges as a better predictor than the CAST.</p

Evolution of quality of life and health‐related behaviors among Spanish university students

Summary At the beginning of their academic studies (testing phase), the quality of life and certain health‐related behaviors were evaluated. Four years later (retest phase), they were reevaluated. Between the two evaluation periods, a health promotion (HP) program was applied. The battery of instruments included measures: health‐related quality of life (HRQOL), alcoholic and nicotine dependence, eating habits, physical activity, and sexual behaviors. It also included a number of sociodemographic data. The results show that, in general, the students reported adequate levels of HRQOL, and there were no important differences between the two evaluation moments. Regarding dietary behavior, no significant changes were detected in the pattern of adherence to the Mediterranean diet, which remained at an average level of adequacy. On the contrary, significant decreases were detected in relation to alcohol and tobacco dependence as well as significant increases in physical activity levels. Lastly, with regard to sexual behavior, although certain aspects of improvement were perceived, there is a need to increase awareness of the systematic use of condoms. In conclusion, this study provides relevant information that will serve as a starting point for monitoring changes in health behaviors and for the design and implementation of HP actions directed at university studentsThis study was partially subsidized with funds from the Vice‐rectory of the Ourense Campus (University of Vigo) and by the Social Council of the University of Vigo., Grant/Award Number: Fiscal year 2016‐2017
