The current research was carried out to study the impact of psychological capital on mental health. Taking this perspective in mind data was conducted on a sample of 200 college students of Haryana within the age group of 18 to 25 years. To measure the mental health and psychological capital of the subjects GHQ-12 (Goldberg & Hillier, 1979) and Psychological Capital Questionnaire (Luthans, 2007) was used. Descriptive statistics, t-test and correlation were implemented by using SPSS20.0. It was found that there is a non-significant gender difference in mental health, psychological capital and mobile usage. A significant correlation was found between psychological capital and Mental Health. In conclusion this can be said that psychological capital variables like resilience, optimism, hope and efficacy influenced the mental health issues in the population of the youth.

We deal with a fractional‐order nonlinear financial model with time delay in this paper. The quantitative analysis of the model has been done in which the asymptotic stability of the equilibrium points of the model have been discussed. Furthermore, the Hopf bifurcation analysis of the model has been done under the impact of time delay. The stability of the model has been studied with the reproduction number less than or greater than 1. The analysis of the model has been done by using the Laplace transformation technique. The analysis shows that the fractional‐order model with a time delay can adequately enhance the elements and fortify the results for either stable or unstable criteria. All unstable cases in the nonlinear financial system are converted to stable cases for fractional order under neighborhood points. The reproduction ranges of all parameters have been discussed. The paper examines the impact of time delay and the importance of determining essential parameters such as saving amount by using Hopf bifurcation. Finally, numerical simulations have been carried out by MATLAB to illustrate our derived results. The financial system is verified under the theoretical outcomes from parameter estimation.
