Abstract:
Objective: This research investigated the psychometric properties of the Self-criticism Scale
(SCS) and Self-reassurance Scale (SRS) among the students in Tehran universities.
Methods: First, the original versions of SCS and SRS were translated into Persian and backtranslated
into English. Then, the scales were reviewed and revised by Psychology professors
and experts. Finally, the 22-item scale was presented to 300 students from Tehran universities.
Results: Using Explanatory Factor Analysis (EFA), three items were removed, and the 3-factor
structure of the questionnaire was supported. The reliability of each factor was also calculated
using Cronbach’s alpha coefficient and was at an acceptable level. Generally, stability and
reliability coefficients for SCR and SRS were satisfactory (P<0.05).
Conclusion: SRS and SCS, form a homogenous set with the appropriate factorial structure
qualified for psychological investigations and clinical application in Iranian society

The present study aimed to evaluate the factor structure, as well as the validity and reliability of the 8-Item Somatic Symptom Scale (SSS-8) in a non-clinical sample of Iranian society.
After obtaining their informed consent, the participants answered Beck anxiety inventory, general health, SSS-8, and somatic symptoms 12 questionnaires.
The present study aimed to evaluate the factor structure, as well as the validity and reliability of the 8-item somatic symptom scale (SSS-8).
Many comparative studies suggest the use of the SSS-8 as a more efficient alternative to the original PHQ-15, especially in clinical settings or in research set-tings with limited assessment time to reduce the measure-ment burden for study participants (Toussaint, Kroenke, Baye, & Lourens, 2017).
The scale of Somatic Symptom Disorder (SSD) The SSS-8 is an abbreviated 8-item version of the PHQ-15 developed by Gierk et al.
