To do so, it relies on the descriptive approach to analyze the relationship between the dimensions of mental health and the criminal investigation. To collect data, a form was designed and distributed to a sample (snowball sample) of 38 individuals consisting only of criminal investigators in the state of Ain Temouchent. Then, the Spearman test and the Kruskal Wallis test were used, relying on the statistical package SPSS26. The results showed no statistically significant relationship between mental health in its dimensions (cognitive, physiological, social, functional, cultural and psychological) and criminal investigation. The results of studying the differences between personal variables and criminal investigation were mixed, while it was concluded that there are differences, there are statistically significant differences between the variables of professional experience, educational level, marital status, and the criminal investigation variable, and there are no statistically significant differences between the variables of age, job rank, type of training, and the criminal investigation variable.othermental health; Dimensions of mental health; criminal investigator; Criminal investigationالصحة النفسية،أبعاد الصحة النفسية،المحقق الجنائي،التحقيق الجنائيThesis
