| dc.description | This study aimed to verify the practical construct and psychometric properties of the DASS-21 scale for measuring depression, anxiety and stress in the Palestinian environment, the study used the descriptive analytical apparoach, while the study population consisted of all members of Palestinian society whose ages range between 20-59 years old; the study sample was determined through convenience sampling, whereas the study tool was an online questionnaire that was sent out to 400 individuals of which 377 responded. The study concluded that the DASS-21 scale was both highly valid and reliable when applied in the Palestinian environment, where construct validity had scores ranging from 0.66 to 0.84, factorial validity was around 0.79 - 0.84, predictive criterion validity (DASS-21 against stressful events, Beck depression inventory) was medium to high, as it ranged between 0.57 to 0.70 for Beck depression inventory, and between 0.71 - 0.79 for stressful events, the scale's reliability scores were also high as the scores with the use of Cronbach's Alpha were as follows: depression 0.929, anxiety 0.914, and stress 0.924, values of the split-half method for the Spearman-brown formula and the Guttman scale were between 0.877 and 0.918 The study recommended the use of the DASS-21 scale in psychological clinics and centres in the West Bank for the purpose of diagonsing depression, anxiety and stress in memebers of Palestinian society whose ages range between 20-59 years old. | en_US |
