Psychometric properties of the perceived stress scale in adults aged 20 to 35 years in the city of Chiclayo

Abstract

The main objective of this research was to determine the psychometric properties of the Perceived Stress Scale in
Adults aged 20 to 35 years of the city of Chiclayo, 2021. The study is of a quantitative type of instrumental design,
the sample consisted of 384 adults who They were selected through non-probability convenience sampling. The
results obtained for validity were developed using the Corrected Item Correlation method, the analysis factor,
extraction values and rotated components obtaining significant values, which is considered acceptable in this
investigation. Subsequently, the descriptive analysis of the items was carried out, which showed indicated indices of
the mean, standard deviation, variance, the coefficient of asymmetry and Fisher's kurtosis; which indicates that all the
reactants have a normal distribution. Furthermore, the reliability analysis was performed using Cronbach's Alpha
Coefficient of 0.806 and Spearman Brown's two-halves method of 0.867. Finally, the percentile scale parameters
were estimated in the following categories: Never or almost never stressed (2-24), occasionally stressed (28-47),
frequently stressed (52-72) and very frequent stressed (82-100), in which the measurement of the variable is
guaranteed. Thus concluding that the PSS-14 has adequate psychometric properties to evaluate the variable.
